00:12 < monteslu> vim plugin? I'm looking for the eclipse plugin and
debugger :)
00:12 < daganev> when you compare it to javascript, you make people think
its a RIA language
00:12 < kingfishr> iant, bingo thanks
00:12 <+iant> Suhail: sure, we're aiming for both, we'll see
00:12 <+agl> monteslu: misc/vim/go.vim
00:12 < Suhail> iant: i guess I am assuming too that development in Go is
not as fast =\
00:13 <+iant> monteslu: no eclipse yet
00:13 < jcgregorio> agl: thanks, let me know if there's patches or tests you
want me to run, since the error seems to not appear consistently across all 9.04s
00:13 < monteslu> daganev, when you compare syntax?

00:14 <+iant> Suhail: thx, two of the creators of Go invented UTF-8

00:22 < Kniht> should I have checked out go into $GOROOT? (or should I set
GOROOT to where I checked it out instead of ~/go?)
00:22 < MarkBao> would it be a good idea to refer to things Go-related as
golang?

user package repository
00:23 < dsal> thiaguetz: I did it wrong initially. It's going for me now.

00:24 < vhold> 6g's default behavior on things that seem like warnings is
interesting.. declaring and not using a variable is fatal
00:24 < vhold> Google's hard line attitude towards wasted variables!
00:24 < sstangl> hm, I wonder why rpike chose names that conflict with the
plan9 C compiler.
00:24 < kuroneko> iant: does it still ignore ABIs? :P
00:24 <+iant> kuroneko: yes
00:24 <+iant> sstangl: they're the same names
00:25 < kuroneko> *sigh*
00:25 < sstangl> iant: I noticed. is anyone working on a plan9 port?

00:29 <+agl> thiaguetz_: you need $GOBIN in your path.

00:34 <+agl> joeyadams: you have a bad value for GOARCH
00:35 <+agl> vhold: party that's a result of all the UTF-8 processing that
you don't see and partly that 6g generates good code, but not great code.
00:35 < thiaguetz> agl: ohhhhhhhhh i got it! i was reading how all.bash
works
00:35 < joeyadams> ah, thanks

00:38 < joeyadams> Is arm a big-endian platform?
00:39 < vhold> agl: is the utf8 aspect only being introduced by bufio? Or
is that happening down at the byte level before stringification ?
00:39 <+agl> joeyadams: typically yes
00:39 < sstangl> opensourcenut: it's true :)
00:39 < kaib> joeyadams: bi-directional but 5g is little endian.
00:39 < sstangl> opensourcenut: I'm writing a driver for it now, actually.
00:39 -!- thiaguetz [n=thiaguet@189.96.212.96] has quit ["[]'s"]
00:39 < joeyadams> So go hasn't been tested on big endian, then?
00:39 <+iant> vhold: the source code is UTF-8
00:39 < opensourcenut> sstangl: Plan9 is quite a difficult operating system
to learn.
00:39 < sstangl> rsc9: I will look into porting Go to plan9 after I have
some more free time to become familiar with the language.
00:40 < kuroneko> opensourcenut: dunno about that - it's different - if you
go in thinkings it's unix, you just make it harder for yourself.
00:40 < sstangl> opensourcenut: there aren't enough resources available, and
most people in my experience are afraid to ask questions.
00:40 < kaib> joeyadams: negative, all the work has been on little endian
configurations.

friendly :)
00:40 < opensourcenut> sstangl: is it?
00:40 <+agl> vhold: certainly it's not happening at the byte level, I
suspect it's happening somewhere in there, but I would have check the sources to
be sure.
00:40 < sstangl> opensourcenut: yes, very.
00:40 < opensourcenut> sstangl: would you use plan9 on a server ?

00:40 < opensourcenut> *production, I mean
00:41 < kaib> joeyadams: at some point part of 5l was in big-endian but we
switched to little endian.
00:41 < sstangl> opensourcenut: I would not trust it to be secure enough to
run facing the world.
00:41 < sstangl> for internal things, it can be nice.
00:41 < opensourcenut> sstangl: but it has such interesting security
features
00:41 < opensourcenut> sstangl: the namespaces and such
00:41 < sstangl> opensourcenut: it's basically a special version of
Kerberos.
00:42 < joeyadams> I got this compiling go: --- FAIL: net.TestDialError

impossible.

00:54 < opensourcenut> agl: Go has the ability to use assembly?

01:43 < gcarrier> lol, that's strange!?
01:43 <+agl> gcarrier: if so, we would be interested to know why :)
01:43 < gcarrier> agl: let me have a look
01:43 < opensourcenut> what causes this?
01:43 <+rsc9> os x firewall assumes all dns requests go through the system
libraries, and ours don't
01:43 <+rsc9> we use udp directly which the firewall does not allow. maybe
it thinks we are some scary p2p app
01:44 < gcarrier> ok, the firewall does open a window to ask for permission
01:44 < gcarrier> but it closes extremely fast
01:44 <+agl> rsc9: there's probably a Mach-port to talk to the local DNS
cache.
01:44 < Go-Nuts> Yeah I saw that and was wondering what happened. was
typing at the time so thought that's what did it
01:44 <+robpike> i've seen that window flash. any idea how to deal with it?
01:44 <+rsc9> even if you grant permission i think it doesn't work. i don't
remember.
01:44 < gcarrier> i had time to allow one, not the other, and now one of the
2 tests run ok
01:45 < harryv> you rendered go! un-googleable :/
01:45 < kuroneko> there should probably be a thing up somewhere that says
that the tests assume internet connectivity.
01:45 <+rsc9> agl: i know, but i've been ducking the implementation of true
mach rpc

01:53 < opensourcenut> I've pulled like 5 times in the last hour haha
01:53 < gcarrier> rsc9: i don't think so. osx just waits for an answer to
bind the socket, so if you timeout and give up it's normal to stop asking for
permission
01:53 <+agl> opensourcenut: you issue has been fixed by a check in. You can
run `hg pull -u` to sync your tree to the tip of trunk.

01:54 < Eridius> err, agl, that page gives erroneous information. It says
to run `hg change` when you're ready to send a change out for review, but that
tells me hg: unknown command 'change'

bug at code.google.com/p/go
01:54 <+rsc9> Eridius: you did not enable the code review extension
01:54 < Jerub> well, basically, there's no way at all to implement a DNS
resolver that matches the rest of the system without loading and calling a library
because nsswitch.conf allows you to provide loadable shared object files as
resolver plugins, which is how mdns works.
01:54 <+ian1> Eridius: you need to add the codereview plugin to your .hgrc
01:54 <+agl> Eridius: you need to install the codereview extension.

01:55 * Eridius has zero familiarity with mercurial
01:55 <+agl> Jerub: yes, this is unfortunate. OS X and (even) Windows are
much better in this regard.
01:55 < Eridius> ahh, I see where it tells me to add that now
01:55 < joeyadams> Reminds me of what happened in #gsoc when people were
waiting for students accepted to be announced.
01:55 < Eridius> silly me, I clicked on the "Make a change" hyperlink at the
top
01:55 <+ian1> Eridius: that's good, because Go's code review plugin is
somewhat different from standard Mercurial
01:55 < Jerub> agl: dns on osx is also weird. there are two resolvers on
the system, and some tools use one, or the other.
01:55 <+agl> opensourcenut: wait, you might be right. You might have a

01:56 * Eridius installed go on two different 10.6.2 systems and had no net issues
01:56 < benno> anyone know if the current build system supports
cross-compiling for arm?
01:56 < brianmacdonald> In
http://golang.org/doc/effective_go.html#web_server line 16 template.HtmlFormatter
01:56 < brianmacdonald> should be template.HTMLFormatter and 33
template.HtmlEscape should be HTMLEscape. See http://golang.org/pkg/template/
01:56 < benno> it doesn't seem to, although it suggests that ARM is support?
01:56 < defectiv> anyone know off hand whot a recent core 2 duo is,
architecturally? 64-bit?
01:56 < opensourcenut> rsc9: okay what information do you need?
01:57 <+agl> Jerub: Linux distros should include a local DNS cache. I have
a NetworkManager patch for that, but it's very hard to get patches into NW.
01:57 <+agl> benno: yes, but some things don't work yet. (Like floats.)
01:57 < Jerub> agl: I'm not trying to say, "you're wrong" - far from it, DNS
resolution by software sucks in huge ways, and the libc resolver is indeed crap
(no way to do an async query for one)
01:57 < antarus> agl: we might have some staff to work on that later this
year
01:57 <+agl> defectiv: Core 2 is typically amd64
01:57 < benno> agl: I don't want floats on arm anyway :)

02:38 < witeness> soul9: you mean in the terminal?
02:38 < soul9> (it's the stuff behind the 4 that counts ;)
02:38 < mrd`> flea__: Have one goroutine manage the map, and have others
send messages and get responses from it.

02:39 < flea__> ok, and so the processing goroutines have a channel to/from

02:39 < soul9> you wrote export PATH=$

02:42 <+rsc9> but if you are sharing something at the granularity of a map,
it's not required to use a channel. for small things sometimes a lock is just
what you want. channels are better for managing overall program structure than

05:01 <+iant> Jerub: it will be \xe1; a string is a sequence of bytes; a
string literal is encoded into UTF-8; you can use range over a string to get UTF-8
characters
05:01 < Jerub> i'm reading the documentation and I don't see this clearly
defined.
05:01 < NelsonLaQuet> That's odd. The only way that I could figure out how
to consume the first return value was to do this:
05:01 < NelsonLaQuet> bytes, errors := io.ReadFile(file);
05:01 < NelsonLaQuet> then write an empty "if errors != nil" statement to
supres the unreferenced variable error.
05:01 <+iant> antarus: that would be a library issue, we'd love to have help
with the libraries
05:01 <+iant> NelsonLaQuet: Use the blank identifier
05:02 <+iant> bytes, _ := io.ReadFile(file)
05:02 <+kaib> harryv: specifically, the android reference platform (and a
large number of the actual deployed arm cores) don't have hardware floating point
support.
05:02 <+iant> Jerub: which part is not well defined?

05:02 < NelsonLaQuet> is there any way to consume a single return value in
the same line? Like: functionCall(multiReturnFunction()[0]) ?
05:02 < shardz> Are there any vim syntax files for Go yet?
05:02 <+robpike> Effective Go covers a lot of this material.
http://golang.org/doc/effective_go.html
05:03 <+robpike> NelsonLaQuet: not smoothly.
05:03 < abbyz> should it not be valid to use [...] as the array size in a
function parameter list?
05:03 < NelsonLaQuet> I read the *very* short section on return values and
it didn't mention any way to do what I want.
05:03 < NelsonLaQuet> shardz: yeah, it's in the repo
05:03 <+iant> NelsonLaQuet: interesting idea, but no
05:03 < Jerub> iant: the unicode/utf-8/string definition. it's clear that
unicode string literals are in the language, but not that the data will be stored
and accessed as utf-8
05:03 <+iant> shardz: misc/vim/go.vim
05:03 <+robpike> arrays are statically sized. ... implies dynamic in that
context
05:03 < shardz> Excellent, thanks.
05:04 < Jerub> iant: I assume that if I have a byte sequence that contains
an invalid utf-8 sequence and I cast it as String, there aren't any possible
errors?
05:04 <+iant> a []byte will convert to exactly that sequence of bytes in a
string
05:04 < _Hicham_> for linux people, put ur environment variables in
/etc/profile.d
05:04 <+iant> they don't have to be valid UTF-8 in that case
05:04 < Jerub> okay, good.
05:04 <+iant> a []int sequence will convert to that sequence of characters,
encoded in UTF-8
05:04 < wcn> Jerub: it returns aninvalid token, but will let you iterate and
recover the rest of the data.
05:04 <+iant> I mean, string([]int)
05:05 < Jerub> wcn: not utf-8 doesn't mean invalid.

the scope of the programming language.
05:11 < bnijk_> there's no way that's true
05:11 < sanxiyn> Strings shall be immutable
05:11 <+iant> bnijk_: if you want a mutable string, use []byte

05:13 < bnijk_> or do you mean, explicit string copying on the part of the

05:13 < dw> hi there. is there a specific part of the language spec that
mentions introspection features? i can't find anything in the docs at all
05:13 < uriel> Jerub: it can be, but dynamic linking is no fun at all, it is
pain and missery all the way
05:13 <+iant> dw: see the docs for the reflect package
05:13 < Jerub> before go gets too big, are there any concrete plans for
package management or a software index?
05:13 < kuroneko> bnijk_: if strings are mutable, you need a distinct copy
reference vs copy contents. immutable strings are always copy reference, but
modifications must yield a new string.

05:39 < dj_ryan> otherwise you cannot write data-intensive database type
systems programming without suffering somewhat
05:39 <+iant> msw: ah, you have a sed which doesn't match centered-dot--that
seems quite likely
05:39 < dj_ryan> Erlang avoids this by having thousands of tiny heaps, each
process is GCed independetly
05:39 < uriel> harryv, iant: thanks, lets see how much code I can get
written once I wake up :) (just moved to a new flat, so Go is going to compete
with actually unpacking my stuff...)

05:40 <+iant> msw: yes, maybe
05:40 < dj_ryan> except they call them 'references'
05:41 <+iant> justinvh: sorry, no syntax for that, have to write a loop or
call a function
05:41 < ajray> dj_ryan: i love watching the CS professors here try to
explain why references are not pointers and how java doesnt have pointers ('unlike
that ugly c')

05:42 < mrd`> Jerub: I think so; it's also process specific because each
process gets its own dedicated heap.
05:42 < NelsonLaQuet> I come from a C++ background - references are typesafe
and don't allow pointer arithmetic.
05:42 < dj_ryan> so are go's pointers pointers or references?

conversation willn ot end well ;)
05:42 < uriel> iant: I got it right though that because Go has no pointer
arithmetic, it could run without an mmu, like Limbo, right?
05:42 < kuroneko> and you can't diddle a reference. :)

05:43 < codedread_> so it was said that go links statically - is that by
default? is there a way to link a go program to libraries built in go?
05:43 < kuroneko> uriel: hey, we had pointer arithmetic before we had MMUs
05:43 < uriel> iant: because that is one of the coolest things about
Inferno, to be able to run reliably and fast on things like the Nintendo DS
05:43 <+iant> codedread_: 6g/8g link statically
05:43 < kuroneko> :P
05:43 < dj_ryan> once you remove arithmetic you cant create arbitrary
pointers, now you have 'references' in the style of java. Aka pointers that have
more working behind the scenes (ie: for compacting GCs)
05:43 <+iant> msw: same error?
05:43 < msw> iant: yea
05:43 < uriel> kuroneko: yes, but I mean safely running multiple programs

05:45 <+iant> NelsonLaQuet: the http library is more aimed at a standalone
server, running under CGI is simpler but I don't know that there is any direct
support for it
05:45 < NelsonLaQuet> nevermind, that's a stupid question... I guess my
question is that are there any nice wrappers for using go as a CGI module under
apache?
05:45 < kuroneko> and it's been done with half-an-MMU (80286 protected mode
lacked the virtual addressing modes, but did have page protection)

05:45 < codedread_> iant: ok, that was how i built my helloworld app, but
would it be possible to link dynamically to libraries built using go?
05:45 < mrd`> _Hicham_: I suspect the Go compiler just uses static linking
because it's simpler, and it's based on the Plan 9 toolchain, which I don't

05:50 < dj_ryan> here's another question, will go be domantly CSP for
multiprocessing? I'm not sure that fits all needs (imagine databases)
05:50 < NelsonLaQuet> I wrote a neat little web server thing that serves out
html templates in a folder; using the request path to locate them. Pretty
neat.... Though am now trying to figure out how I would implement a nice
web-centric MVC framework and OR/M over this. It's architecture is really
different then other languages...
05:51 < javarants2> there is an http server in the http library
05:51 < javarants2> i think it is the one that is serving their site
05:51 < DJCapelis> databases are not worth designing for I think... they
always mess things up and the hacks you have to put in to support them seem to be
rarely helpful to anything else.
05:51 < NelsonLaQuet> yeah, I cheated and used that. But I would prefer to
expose any application over fast CGI so that I can take advantage of apache's
other features and stability.
05:51 < antarus> dj_ryan: It may be that go is not a good language to write
certain kinds of applications in.
05:51 < mrd`> [absolutist argument with zero support]
05:52 < dj_ryan> antarus: uh, then wtf is it for?!
05:52 < no_mind> DJCapelis, but you still need databases.. they are
necessary evil in comp applications
05:52 < dj_ryan> if you cant write a database in a systems programming
language, what kind of systems programming language is it
05:52 < javarants2> i didn't see native support for C libraries, is that in
there somewhere?
05:52 <+iant> dj_ryan: go uses goroutines and channels, yes, it's the ideas
from CSP plus a bit more

writh in go.
05:52 < codedread_> i think i would really like to see dynamically linked go
programs (with the 'go' standard libraries available as shared object libraries)
05:52 < dj_ryan> so with CSP you just bottleneck for certain things
05:52 < DJCapelis> NelsonLaQuet: Use databases with go all you want.
05:52 < dj_ryan> eg: ETS tables in erlang are bottlenecks
05:52 < no_mind> DJCapelis, so we should drop go for db related apps ? that
means 90% of web apps
05:52 < mrd`> dj_ryan: Not true.

05:53 < DJCapelis> no, I just said the actual databases themselves.
05:53 < joeyadams> I guess go doesn't have DB packages yet?

05:53 -!- Robdgreat [i=rob@unaffiliated/robdgreat] has joined #go-nuts

05:53 < dj_ryan> DJCapelis: right, writing data storage systems in go might
be interesting, since your choices are mostly Java and some C++ (sorta)
05:53 < DJCapelis> no_mind: using a database maps nicely into goroutines.
05:53 < joeyadams> Does it have good reflection support for tasks like

05:54 < antarus> joeyadams: I suggest you check out the unsafe module
05:54 < NelsonLaQuet> I'm assuming that we can link go with C code, though,
right? With the gogcc compiler? In that case you could re-build the C libraries
for mysql and whatever, then build a nice OR/M over that.
05:54 < antarus> joeyadams: (which is where all the reflection is, afaik)
05:54 <+iant> Go is definitely not Erlang
05:54 < javarants2> iant: how would you compare goroutines to libdispatch +
blocks? i have been looking at that and it solves quite a few of the annoyances
in writing concurrent C code.
05:54 < DJCapelis> NelsonLaQuet: you can, it's unsafe though, generally...
05:55 < NelsonLaQuet> true
05:55 < no_mind> where do I find db packages for go ?
05:55 < joeyadams> Hmm, I wonder manually implementing a "work queue" is
typically necessary in go
05:55 < dj_ryan> there is this strong trend in the open world for large data
scale things to be written in Java (see: hadoop, et al)

05:55 < ajray> if i wanted to contribute the bash completion file to

non-existent. It is only used in terms like "compatibility" and "community".

make calls outside of your own internal ABI

cores dynamically, which some power management tools might want to do)

06:48 < chrome> ah hmm.
06:48 <+robpike> there is already runtime.GOMAXPROCS(int)
06:48 <+agl> scriptdevil: it's a little odd, but you can probably ignore it.
06:48 < joeyadams> I just ask because runtime.GOMAXPROCS(int) looks kinda
hackish (with the capital letters)
06:48 < scriptdevil> agl: :) Thanks
06:48 < antarus> It looks hackish because commented above it says "this
should go away when the scheduler is improved" :)
06:49 < joeyadams> and if the num cpus function doesn't need to go in
runtime because syscall exists, we'd have two similar-purpose functions in two
different modules
06:49 <+robpike> joeyadams: it's spelled like that because of the env var.
you're right it looks hackish.
06:49 < drusepth> I just read about Go on /. and am considering looking
into it tomorrow (it's a bit late tonight), but I'm curious whether it has

making it based on the repo would be fine, but you still have the env var issues

different types, no. see the language design faq

07:45 <+robpike> jdp: no plans. are they a problem other than the initial
setup? we crosscompile all the time and being able to flip builds is very handy
07:46 < jdp> no they aren't, you're right
07:46 < scriptdevil> sjbrown_: Can Google ever go wrong is the question. I
dont wanna sound like a fanboy. But I am positively amazed at the maturity and
completeness of a 2 day old language. (Forget the 2 years of development)
07:46 <+robpike> you need asn1 for x509 for SSL
07:46 < Eridius> robpike: I'm of the opinion that crosscompiling should be
achieved by passing -arch flags to the compiler
07:46 < Eridius> and with that, I'm going to sleep. g'night
07:46 < uman> when (if ever) will Go be available for Windows?
07:46 < KiNgMaR> <- wondering about Windows support as well
07:47 < mjard> heh
07:47 < epalm> windows isn't mentioned anywhere in the faq
07:47 <+robpike> Eridius: that means different makefiles and all that, or
else some other configuration management setup. env vars work great
07:47 < sjbrown_> scriptdevil, are you waiting for the Google Bob?
07:47 < mrd`> Pft, use a real OS. :P
07:47 < uman> also, my humble recommendation is that you put this in the FAQ
07:47 < uman> mrd`, that's a useless answer
07:47 < theatrus> oh I missed the whole ssl library, last I dealt with asn1
was with SNMP on embedded microcontrollers
07:47 <+robpike> uman: you're right
07:47 < mjard> uman: you have to respect the fact that it's very very rare
that the tables are turned this way
07:48 < eydaimon> Eridius: I'll email you the ticket

prediliction for unxstyl names
07:48 < eydaimon> Eridius: I'll file it as per usual
07:48 < antarus> Eridius: meh, I dunno when I cross-compile I typically set
CHOST, CTARGET, etc...and my build system handles talking to the compiler for me;
I don't see how this is conceptually different?

are advantageous mostly when *reading*
07:54 <+robpike> Morphius: have you done hg pull -u recently? some network
bugs were fixed tonight
07:54 < epalm> should go code be written with the number of available

10:46 < voxadam> I just watched Pike's Go presentation at Google on YouTube.
He mentioned that there was work underway (or maybe scheduled) to replace the
current mark-and-sweep GC with something more advanced. Specifically, he
mentioned The Recycler from IBM. IBM claims a maximum pause time of 2.6 ms. If
this is true what are the chances of Go being suitable for real-time/deterministic
programming?

things.

E.g. Ubuntu generic kernel peaks 50-100 ms latency spikes all the time, while
many other distributions (and Ubuntu rt kernel) can keep latencies under a few

11:41 < deafmetal> i have a rather noobie question...
11:42 < deafmetal> I'm getting an error when i try and run all.bash
11:42 < deafmetal> liek so: $GOROOT is not set correctly or not exported
11:42 < npe> deafmetal: did you add GOROOT to your bashrc and export it?
11:42 < deafmetal> GOBIN=/Users/deafmetal/bin
11:42 < deafmetal> GOARCH=386
11:42 < deafmetal> GOROOT=/Users/deafmetal/go
11:42 < deafmetal> GOOS=darwin
11:42 < deafmetal> yes.
11:43 < deafmetal> that's the result of my env } grep
11:43 < Element14> did you explictly export it?
11:43 < npe> bash -c 'echo $GOROOT'
11:43 < npe> see if you're successfully exporting it.
11:43 < deafmetal> ok
11:44 < deafmetal> deafmetal-2:~ deafmetal$ bash -c 'echo $GOROOT'
11:44 < npe> and nothing?
11:44 < deafmetal> no, it gives me the path
11:44 < madac> Put export in front of everything, e.g.:
11:44 < madac> export GOBIN=...
11:44 < alt^255> deafmetal: in the same terminal where you're running

however small, on my Linux machine. Maybe then getting into the coolness of Go
once I understand it better. In this case I'm coming from a sysadmin role, not
really a programmer yet.
11:53 < blasdelf> it's more about trying the kind of toy problems that lend
themselves to CSP

11:56 < alt^255> what about plan9 and inferno, how they relate to Go?
11:56 < Innominate> leitz: Can't hurt to try, but an experimental language
is probably not the best place to start
11:57 < blasdelf> alt^255: written by the exact same authors, espousing many

11:57 < hnsr> anyone know what I might be doing wrong here?
http://pastie.org/693501 it fails to find quietgcc even though it is in my PATH,

11:57 < leitz> Innominate, I'm rather slow sometimes, so the language will
mature faster than my programming. :)

12:01 < nacerix> hi all
12:01 < alt^255> madac: I already like this.
12:01 < blasdelf> madac: It has interfaces
12:02 < blasdelf> It seems that they've avoided GADTs, possibly because they
don't mesh with Protocol Buffers
12:02 < madac> blasdelf: Interfaces and generics are orthogonal concepts.
Yes, they both support polymorphism, but in very different ways.

14:56 < watermind> engla, temoto: is there any obvious reason why it's
inclusive on left and exclusive on right??
14:56 < Cool_Fire> 1. Is there (any plans) for a IDE for go?
14:56 < nc> _dr: i came across a new error though, much further down the
line of execution... so if you're gonna build on OpenBSD or a system that doesn't
use gmake by default, just make sure you change 'make' to 'gmake' in *make*.bash
14:57 < temoto> watermind: i actually find it useful in some cases. I need
to provide good example, but i don't have one in mind right now.
14:57 < Cool_Fire> 2. What about GUIs?
14:57 < engla> watermind: there are two good reasons. 3-1 = 2, so we should
make the interval halfopen. and -1:2 to include 0,1,2 would suck so 0:3 for 0,1,2
is better
14:57 < scriptdevil> Cool_Fire: It has good support for vi, emacs, xcode
14:57 < Cool_Fire> ok
14:57 < _dr> ok thanks nc, alias make=gmake should do
14:57 < engla> watermind: you should ask dijkstra about this

interval of indices. ewd suggests that experiment shows that other conventions
than [,) are confusing. I think that [a,b) with len = b -a is very logical.

obvious that the cost is proportional to the length of the slice.

16:12 < mmu_man> $BASH stuff shouldn't actually be needed, but it wouldn't

16:13 <+agl> me__: well, we don't link again libc so using pthreads wasn't
an option

16:21 < Associat0r> iant also the lack of operator overloading or at least
defining bothers me

just an alternative
16:21 < me__> hmm, when using limbo, i found i wanted weak refs; have there
been any thoughts towards that?
16:21 < monov> iant: ok
16:21 <+iant> Associat0r: the language is not fixed in stone but I doubt Go
will ever get operator overloading
16:22 <+iant> me__: I have not heard any discussion of weak refs
16:22 < Associat0r> iant the thing is I do a lot of numerical stuff and
having to have method names for math operetors is not so nice
16:22 <+iant> Associat0r: understood; language design is always a tradeoff

16:22 < mpowers> I'm curious about how Go achieves such awesome compile
times relative to C/C++. Is there a quick answer for this, or a writeup of the
techniques used to improve compile speed?
16:22 < Wezz6400> Being a fan of C++ I don't mind Go being different, C++
already exists so to create something very similar would be pointless imo
16:23 <+iant> mpowers: the main reasons are the simple syntax and the
package system
16:23 < ag90> I'm curious. Go has some amount of C interoperability. Am I
right?
16:23 -!- blackmagik [n=blackmag@unaffiliated/blackmagik] has joined #go-nuts
16:23 <+iant> ag90: limited but yes, see misc/cgo for an example; it's not

16:23 < Associat0r> iant that I understand, OCaml also made that tradeoff
16:23 <+aclements> me__: Russ and I did discuss weak refs a while back. I
believe the conclusions was that Go needs something like weak refs.
16:23 < pbunbun> iant: So you're saying it's the language itself being easy
to compile, not just the compiler being good?
16:23 <+iant> pbunbun: the compiler is good, but, yes, the language is the
key
16:23 < thotypous> does anyone have an example using closures please?
16:24 < Associat0r> Wezz6400 well I don't want Go to be similair to C++, but
at least do what C++ can do
16:24 < mpowers> so there is no preprocess step in Go, i guess?
16:24 <+iant> thotypous: there are some examples in the course slides, I
think on day 2
16:24 < pbunbun> iant: So the gcc-based compiler is (or should/could be) far

16:24 < pbunbun> Ok cool, (haven't actually downloaded it yet, when I get

16:24 < ag90> So does that mean it is possible to bind libraries like GTK to

16:25 < albertito> iant: thanks!
16:25 <+iant> Associat0r: gccgo does it, I don't know offhand whether 6g/8g
do it

16:25 < Associat0r> Wezz6400 who said it's little functionality?

16:27 < mpowers> out of curiosity, besides preprocessing, what are the
language features of say, C, which cause the most amount of "work" for the
compiler, and how does Go fix that? Do these improvements come "free", or is
there a cost paid in complexity/readability of code?
16:27 < Associat0r> Wezz6400 well it's not just C++ that does op overloading
also asking about GC is a valid question since it's a systems language
16:28 < ment> mmu_man: hmm s/waidpid/waitpid/ maybe?

slower than reading in compiled package information

parse, notably the declaration syntax

18:21 < three-f-jeff> kaib: one of my first thoughts when reading the docs
on golang.org was "how would this work for implementing a kernel", and you would
want to do the entire thing in go, but you'd have to customize the gc to work at
the kernel level (eg, being mindful of page tables and segments)

18:33 < NfNitLoop> bear: Oh, huh. trying the pull now.
18:33 * techknowlust checks zsh command history
18:33 < techknowlust> one sec
18:33 < techknowlust> bear: hg clone
18:33 < musty> jvogel_, *shrug*
18:33 < musty> hg clone -r ?
18:33 < swamytk> the compilation of go took around 2 to 3 mins in AMD Quad
core machine with 4GB RAM on ubuntu 9.10
18:33 < bear> techknowlust, yea, try: hg pull -u now and see if you get some
new updates
18:33 < techknowlust> I'm not familiar with mercurial, could this be the
cause of my problem?
18:33 < techknowlust> ok
18:33 < PHG> after you pull, you have to update
18:33 < PHG> iirc?
18:33 < NfNitLoop> techknowlust / bear: ah, yep, I see changes.
18:34 < musty> that's what -u does
18:34 < musty> iirc
18:34 < PHG> i'm sorry
18:34 < NfNitLoop> seems strange to have to pull immediately after cloning.
18:34 < NfNitLoop> (coming from bzr) :p
18:34 < temoto> Hey, BTW, shouldn't ./all.bash run some make with some -jN?

right now
18:34 < musty> jvogel_, your wish has been answered.
18:34 < techknowlust> bear: if I clone would the .hg directory be included ?
18:34 < JakeSays> so no go for windows? :(
18:34 < musty> Did anyone have qualms when installing with bash?
18:34 < emet> this web server code example is pretty cool
18:34 < temoto> I see MAKEFLAGS=-j4 in make.bash. Great.
18:34 < jvogel_> musty: hehe
18:35 < emet> no I got it to compile and install
18:35 < bear> techknowlust, after running hg clone you should see a .hg dir
as part of the new files - yes
18:35 < emet> it was necessarily hard IMO, maybe use autotools next time?
:o
18:35 < PHG> i have a question though, why so many gotos in the source?
18:35 < PHG> though i havent looked through much.
18:35 < weggpod> how to convert string in int when is it possible
18:35 < weggpod> ?
18:35 < musty> jvogel_, Going to /QUERY him now? :)

required argument to the hg pull command

18:36 < olegfink> silly question: I'm trying to call an anonymous func from
itself. The first idea was to just generate an OCALL with curfn->nname, but of
course anonymous funcs don't have ->nname. Is the only possible way to do this
is to add OCALLSELF in addition to OCALLFUNC and implement that in the backend?
18:36 < pancake> musty: yeah sorry im just busy at work
18:36 < bear> emet - it's a bootstrap compiler environment that is in flux -
i'm sure once they get the crosscompiler set for each environment i'm sure the

18:57 < charles_> iant, I know tradition and all, just a little easier than

18:57 < temoto> compared to nonexisting python optimizer
18:57 < bobappleyard1> emet: yeah, pretty much. an object implements an
interface if it has the required methods

18:57 -!- mode/#go-nuts [+v agl] by ChanServ
18:57 < emet> but the object doesn't need to even know about the interface
right?
18:57 < tetha> temoto: you do know that there are optimizing python
implementations around?
18:57 < bobappleyard1> emet: no it doesn't
18:57 < fynn> temoto: ... that's comparing apples to oranges.
18:57 < emet> that's awesome
18:58 < grawity> I just tried building Go on a Debian 5 VPS, and all the
final tests fail with "cat: /tmp/gotest1-1247-grawity: No such file or directory"
(http://phoenix.binaryhex.com/~grawity/all.bash.log)
18:58 < emet> that is really cool
18:58 < temoto> emet: no objects. The best implementation of object model.
18:58 < engla> temoto: google is working on optimizing python ;-) among
others
18:58 < charles_> inat, BTW very good job so far, it is at the right place a
the right time, (25 year C programmer here). ;)
18:58 < temoto> tetha: do you mean unladen?
18:58 < saml> can i build using mingw?
18:58 < emet> unladen swallow
18:58 < olegfink> iant, I was trying to call an anonymous func from itself.
The mst obvious (and wrong) idea was to generate an OCALL with curfn->nname,
and the only other option I see is to add OCALLSELF in addition to OCALLFUNC and
implement that in backend, but that look awful. Do I miss anything else?
18:58 <+iant> grawity: I don't see that in yoiur log
18:58 < three-f-jeff> emet, temoto: the 'no objects' OO is what blew my mind
when I read the specs.
18:58 < tetha> temoto: unladen, pypy, jython, ironpython, w/e

there's no bin ...
18:59 < e2d2> musty, i had that when i didn't have $GOBIN in path

users...
19:02 <+iant> well, we're not distro maintainers

19:04 < bobappleyard1> travisbrady: members?
19:04 < phoodle> three-f-jeff: no, i'll add it
19:04 <+iant> You need to do for p := range f.Iter() { e := p.(string);
19:04 < bear> charles_, the issue of app installs is moot with a single
binary generated by the compiler - you just have to ensure you have binaries for
all target platforms
19:04 < eno> iant: besides pkg and GOBIN/*, what need to be in distribution
for a golang package?
19:04 < bear> charles_, but if the language starts generating traction and
libraries become common, then package management becomes an issue and that's a
whole other pain in the tuckus

19:05 < delza> phoodle: I had the same problem. You $GOBIN has to be in
your path, has to exist, and it can't be in your path as "~/bin" but works as
"$HOME/bin"
19:05 < bear> charles_, not yet as the compiler generates very specific
instructions - you could try the gccgo frontend but even that would generate
specific arch targeted binaries
19:05 < ment> iant: works, thanks
19:05 < phoodle> three-f-jeff: thanks, adding to path seems to work, is now
compiling, delza: thanks as well
19:05 < charles_> bear, I only mention it because it is hard, if it was
easy, I'de have the solution
19:05 < travisbrady> bobappleyard1: the number of people in this channel
19:05 <+iant> eno: I think that's it
19:06 < ajray> is there a Go book yet?
19:06 < bobappleyard1> travisbrady: oooh i see
19:06 < Selar> geez
19:06 < charles_> bear, need to think ahead if possible
19:06 < bear> charles_, hehe - true - but I think the golang guys are
working on the "crawl" phase before they can get to the "sprint" phase that is
what distro packages are (IMO)
19:06 < Selar> it just came out
19:06 < Selar> the tutorials and videos are awesome right now
19:06 < KillerX> why can I not do this: http://pastebin.com/m5d74a6df (using
a struct type as values in a map)?
19:06 < bear> charles_, yea, the issue will become important as soon as they
allow for linking to outside libraries
19:06 < charles_> bear, the key to a system is design and getting that
right, MUCH hard to re-design than the other way around

20:04 < ajhager> agl: I've seen this possible in Python's ctypes, but I've

20:04 < temoto> Yeah, i'd like to see 1_000_000 too.
20:04 < KirkMcDonald> So 1_000_000 is a valid literal in D.
20:04 < Dreamr_3> so is there a textmate syntax? :)
20:05 < glewis> In D, you can also use $ with an expression, like buf[1:$-1]
20:05 <+agl> ajhager: what you can't do is pass a pointer to a Go function
into C. I don't know the specifics of the GL libs however.

think go does it better.
20:16 < ajray> also, i'd like to add my voice to the templating question.

20:16 < diabolix> I think if you need a complex feature, the language should
provide a means to add it, not depend on it.

20:17 < kmc_> with nulls, unless you have some way to structure computation
(e.g. monads), you end up writing "if (x == NULL) return NULL" every other line
20:17 < diabolix> like, why can't the 'go' keyword be a function that takes
a closure as an argument?
20:17 < ajray> diabolix: would templating qualify as a complex feature?

20:22 < aaront> check the permissions on bin
20:23 < Dreamr_3> string#Join
20:23 < ajray> Dreamr_3: strings are immutable, byte arrays are not.
20:23 < danderson> diabolix: goroutines, due to their form, need support
from the runtime to be able to multiplex several goroutines on a single thread.
So from that point, they must be in the runtime. As for why the syntax is a
keyword rather than a function, I don't know and defer to the creators of the
language for widsom.

22:26 <+iant> I do not have any idea, we aren't working on one ourselves
22:26 < timmcd> iant: How many people are currently working on the Go
source, improving the language? (as we speak, that is.)
22:26 < KirkMcDonald> I am still not sure what to think of the fact that a
package implies nothing about the source files which comprise that package.
22:26 <+iant> the team at Google is five or seven people, depending on how

22:27 <+iant> keithcascio: yes, all files in a package must be passed to 6g

specific niches, and that it's clear Go has application beyond those niches.
22:30 < hhg> fynn: Go should also be useful for writing massively scalable

22:33 < hhg> fynn: you would write goroutines that block on i/o, like a unix
process dealing with a single client, and you can use all the structured
constructs (loops, etc.) and it just blocks when it needs to and the state is on
its stack. you don't get into the awkward model where you have inversed all the
control with a "reactor" like event structure, where things subscribe to be called
22:33 < keithcascio> +iant, +robpike: all of java's most important packages

copy/pasting the body of the embedded object into the embeddee
22:58 <+iant> that is, given []SantasHelper, where SantasHelper is an
interface, you can assign a Reindeer to an element of that slice

the embedded object too

runtime.Goexit(); then you don't have to pass errors up a chain

multiple changes in one tree
01:24 <+iant> ajray: otherwise, yes, different checkouts or different
branches or whatever seems best
01:24 < ajray> is that how i keep the different files separate then (remove
lines from submission file)?

for them
01:33 < ajbouh> i have some simple ideas, half-baked ideas on the subject -
is this the right forum for that?
01:33 < ajray> is there any code-diving tools for go? (like go-scope
instead of cscope?)
01:33 <+iant> droid0011: right, it's not in libc-dev, it's in linux-libc-dev
01:33 <+agl> droid0011: I don't believe that files in /usr/src are in the
search path for includes.
01:33 <+iant> which is a different package
01:33 <+iant> agl: droid0011 is trying to build gccgo
01:33 <+agl> iant: ok, I'll let you handle it then :)
01:34 <+iant> ajbouh: the mailing list may be more useful, unless they are

01:36 <+iant> ank3but_: at the moment, I think so, but as other people learn
the system and show good work we plan to add them
01:36 < ajbouh> iant: any reason you guys haven't gone with something like
"go func () { .. }, chan os.Error"
01:36 <+iant> like other open source projects
01:37 < ank3but_> iant: Okay...
01:37 <+iant> ajbouh: we've considered that and it may happen at some point,
but no promises
01:37 < ank3but_> go is interesting.
01:37 < ajbouh> iant: and you're suggesting that building something like
that would involve a lot of runtime hacking?
01:38 < ank3but_> i search for a while an other language but C was the best
for me.
01:38 < ank3but_> go looks cool
01:38 -!- Ruonkrak [n=john@74-140-218-7.dhcp.insightbb.com] has joined #go-nuts
01:38 <+iant> ajbouh: I don't think it would take that much hacking, it's
more a question of whether we think it is a good fit for the language
01:38 <+iant> we're trying to be very careful not to add unnecessary
features
01:38 <+robpike> ajbouh: the idea of getting a channel from a go f()
invocation makes sense. i've thought about it a lot, though, and worry that it
may be more complicated to do than it's worth. but we are still talking about it

for error handling - it turned out much simpler + robust than we expected
01:42 < nutate> Eridius: I just want to see if I can make sense of this from
the multicore standpoint... I know enough to be dangerous with pthreads, openmp,
cuda, etc...

01:42 <+robpike> ajbouh: is it written up?
01:42 < engla> since it would be hard to implement map(func, array)
correctly in the type system, what about list comprehensions ala Python; can
syntax support solve this;perhaps: a := [f(x) for _, x := range otherarray]
01:43 < kfx> droid0011: check libc6-dev
01:43 <+iant> engla: we do have range

01:43 < SRabbelier> is it possible in one line?

01:43 < rando> iant: ah, OK. that makes sense. I do like the direction of
this language. I think rob hit it on the head, programming became 'not fun'
unless you used a dynamically typed language. I'll be watching. As soon as I
think it's solid enough I'll try to use it in my production environment.
01:44 < SRabbelier> robpike: what's the goey way to do it?
01:44 < KirkMcDonald> robpike: So the elements of this dynamic struct have a
static type of reflect.Value. If I wanted to pull a static S out, I would say:
(*S)(unsafe.Pointer(field.Addr()))

01:44 <+iant> SRabbelier: I'm not sure just what you are trying to do,
actually
01:44 < KirkMcDonald> robpike: (After confirming that the type is, indeed,
that.)
01:44 <+robpike> SRabbelier: does foo() return a pair?
01:44 < rando> Eridius: I looked at it.... my head hurt.
01:44 < SRabbelier> robpike: yes, the usual 'value, err' pair
01:44 < Eridius> rando: hehehe
01:44 < SRabbelier> I'm implementing fibonaci to practice
01:45 < KirkMcDonald> robpike: Since unsafe.StructValue doesn't have a Get
method.
01:45 <+robpike> KirkMcDonald: you do not need package unsafe. you should
almost never need it.
01:45 < danopia`> rando, lisp is fun
01:45 < SRabbelier> and I see no elegant way to do the fib(n-2) + fib(n-1)
01:45 < KirkMcDonald> robpike: Er. reflect.StructValue, I mean.
01:45 < SRabbelier> (with fib returning value,err)
01:45 <+robpike> KirkMcDonald: reflect.StructValue has a Field(int) method
and NumField()

when you are caught fooling around
01:48 < droid0011> kfx: yes sure, it is in

02:03 < JBeshir> foo[0:len(foo)] seems... long.

02:04 < JBeshir> KirkMcDonald: So I can add it to an array.
02:04 < danopia`> gointrigue, did you use double quotes
02:04 <+robpike> JBeshir: if foo is an array and you want to promote it to a

02:05 <+robpike> KirkMcDonald: which is weird?
02:05 < Eridius> the biggest issue with making a git mirror is you can't
participate in the code review process
02:05 < SRabbelier> danopia`: I'm pretty sure that the github guys are
working on that regardless using hg-git
02:05 < KirkMcDonald> robpike: That &array gives a slice over the array.
02:05 < JBeshir> "cannot use &main_parameters[i] (type *string) as type
[]string" <-- Doesn't seem to work?
02:05 < KirkMcDonald> robpike: Maybe I am too used to C.
02:05 <+robpike> KirkMcDonald: actually it makes a lot of sense. a slice is
a reference to an array. &array doesn't become a slice, but it can be assigned to
one

03:06 < Ycros> Rob_Russell: ReadString only exists on bufio.Reader, not on
io.Reader, and it takes a delimiter to stop on - I just want to read the whole
thing into a string
03:06 < dgnorton> chrome: also had to "hg pull -u" before ./all.bash would
run clean
03:07 < ajbentley> anyway, i got it to build as far as it did by specifying
bash and gnu make instead of the defaults, but it dies building gopack
03:07 < Ruonkrak> was pleasantly surprised that ./all.bash ran clean (second
time) on Ubuntu after all prereqs were installed (386)
03:07 < Ycros> Rob_Russell: I mean, it works, if I pass in null as a
delimiter byte, and work on err == EOF. But I have to create a buffered reader in
between as well. It feels too verbose, and like there should be a simpler way of
doing it
03:07 < bobappleyard1> Ycros: io.ReadAll ??

There is struct B having an anonymous field A. stuct A has two methods attached:
A1, and A2. all that A1 does is call A2. B overrides the method A2. if i call
binstance.A2 then i get B.A2. If i call binstance.A1 then i get A.A2. is there a
way that i could get B.A2 in both cases?
04:38 < kmc> so is the conversion from my-concrete-type to interface{} and

04:42 < Ycros> gointrigue: yeah, it seems like there are issues with gccgo -
do you need gccgo as opposed to the default compiler?
04:42 < kmc> NfNitLoop, aren't interface methods basically virtual?
04:42 < NfNitLoop> and in fact, all those methods still seem to operate on a
struct that is the "superclass" equivalent.
04:42 < gointrigue> No, I was merely curious about using itt.
04:42 < ablegreen> what do you guys think of the language so far? I am
looking at the sample code and it doesn't seem to be simpler than C

04:42 < NfNitLoop> kmc: In a way, but not like virtual methods in C++ or
Java.
04:42 < pandrew> NfNitLoop: the way i see it each method is both virtual and
static. depending on how you call it. if you call it trough an interface it is
virtual. What i'd like to see is the ability to have a method with an interface
receiver, or something like that.

Library to be used with Go? ie, Ncurses?
05:09 <+iant> timmcd: do you mean to rewrite it in Go? Or do you mean to
call the C/C++ library directly from Go?
05:09 < kuroneko> libgo is good so far
05:09 < KirkMcDonald> Hmm. Not certain how to narrow down this segfault.
05:09 < chrome> timmcd: see misc/gmp

reflect.Value.

05:31 <+iant> easiest is make([]byte, 24)
05:31 <+iant> or you can do "var buf [24]byte" and pass "&buf" to Read
05:31 < Jerub> my brain parses [24]byte as a pattern matching 2byte and

05:32 < xor> Hi there.
05:32 <+iant> ArekZB: not really; taking the address of thing will make the

05:33 < ajray> is anyone working on git tools for go?
05:33 < dsal> iant: passing &buf doesn't compile. Nor does make: cannot use
make([]uint8, 24) (type []uint8) as type *[24]uint8 :/
05:33 < xor> Where can I find tools to help develop with go? I mean, is
there an Eclipse plugin, emacs plugin, something?
05:33 < ajray> xor: check the misc dir

05:33 <+iant> dsal: read doesn't take *[24]uint8, it takes []uint8, doesn't
it?
05:33 < dsal> Correct.
05:34 < xor> ajray: Thanks, will do.
05:34 <+iant> dsal: so where does *[24]uint8 come from in the above
05:34 < ajray> xor: i thats vim/emacs
05:34 < dsal> var hdrBytes *[24]byte = make([]byte, 24);
05:34 < ajray> i dont know about eclipse, but i'd love an eclipse plugin
05:34 < chrome> dsal: you can just do hdrBytes := make ([]byte, 24);
05:34 <+iant> dsal: ah, no, it has to var hdrBytes []byte = make([]byte, 24)
05:34 < ajray> xor: i'm also playing with the idea of making a cscope-like
goscope for code-diving in go
05:35 <+iant> or just hdrBytes := make([]byte, 24)
05:35 < ArekZB> xor: i don't think there is an eclipse plugin yet . as far

05:35 < Rob_Russell> weird that for a:=0, b:=10 ; a < b ; a++ {} is

05:58 < kmc> object casting is the best part of java?
05:59 < Jerub> kmc: uh, the lack of object casting brought in by generics
and auto-boxing i think he means.
05:59 < chrome> from what I can see, go doesn't *need* generics; it does
essentially the same thing with interfaces, but without the clumsy syntax.
05:59 < itrekkie> hi everyone, can someone clue me in on the -I flag for
6g? I'm trying to use a makefile to build .6 files (objects?) in a directory
sitting next to a src directory, but I cannot fix this "cannot find import"
problem. Are there some docs I'm missing; does anyone have a Makefile or similar
solution they'd be willing to share?
06:00 <+robpike> chrome: not quite. the unboxing is annoying and it's not
trivial to create a type-safe container. there are subtler advantages of generics
too. but they are tricky to get right
06:00 < KirkMcDonald> itrekkie: .6 files are both object files and header
files.
06:00 < tetha> chrome: I'd argue that no one needs that akward hack generics
are ;)
06:00 < KirkMcDonald> itrekkie: You use -I to point the compiler at the .6
files required by the package you are compiling.
06:01 -!- Speciak [n=kevinbum@c-98-213-173-184.hsd1.il.comcast.net] has joined
#go-nuts
06:01 < kmc> chrome, with generics you could write "map" without the
unnecessary runtime cast
06:01 < KirkMcDonald> itrekkie: Or, rather, to point the compiler at the
directories in which the .6 files are contained.
06:01 < Speciak> anyone want to give a beginner a quick run down on the go
language?
06:01 < wcn> robpike: as an implementer, what are some of the tricky
aspects?
06:01 < gointrigue> that command is borked
06:01 < itrekkie> KirkMcDonald: and the syntax for the flag is -I dir/,
-Idir/ or does it matter?
06:01 < ment> Speciak: http://golang.org/doc/go_tutorial.html
06:01 < chrome> kmc: coming from C that cast doesn't seem burdensome to me
06:02 < gointrigue> but it compiles now...
06:02 < KirkMcDonald> itrekkie: Both should work.
06:02 <+robpike> itrekkie: there's a subtle issue. if you don't install the
.a file into the pkg directory, like the makefiles in the existing pkg dirs, then
you probably want to write your imports as ' import "./file" ' so it finds them in
the current directory
06:02 < KirkMcDonald> itrekkie: But it must go first, before any of the .go
files.
06:02 < Speciak> I read the tutorial... is there any way to program in go
on windows?

07:48 < Ycros> it is relevant, because you're pointing out how long your
program is, and claiming it shouldn't be using that amount of ram for its length
07:48 < zeebo-> the real question is, what does number of lines have to do
with ram usage of the program, and the answer is nothing
07:48 < kmc> it's maybe a little correlated to the code size, but that's
probably a small component of overall RAM usage
07:48 < Ycros> JBeshir: I never saw your core - do you have a link to it?
07:48 < JBeshir> Ycros: No, I'm saying "Should a fairly typical small
program use 6MB of RAM in Go?"
07:49 < kmc> JBeshir, what does it do?
07:49 < zeebo-> it depends on how much memory it allocates in the program
07:49 < kmc> if you answer that question it will be much more useful than
knowing how many lines of code it is
07:49 < JBeshir> kmc: It opens a socket connection and reads from it.
07:49 < kmc> reads into a buffer of bounded size?
07:49 < JBeshir> Does stuff on each received line then forgets about it.
07:49 < JBeshir> Yes; 512 bytes
07:49 < kmc> are you sure it's forgetting about each line?
07:49 < JBeshir> It's garbage collected and only has so many variables.
07:50 < JBeshir> It's also not receiving anything near that amount of data.
07:50 < JBeshir> A few KB would be a pretty big overestimate

08:29 < Ycros> zeebo-: yeah, I just searched my IRC backlog - apparently you
can set GOMAXPROCS as an env var
08:29 < zeebo-> mike_storm: my guess would be threads
08:29 -!- Fish- [n=Fish@78.238.225.114] has joined #go-nuts
08:29 < zeebo-> from the docs: "GOMAXPROCS sets the maximum number of CPUs
that can be executing simultaneously. This call will go away when the scheduler
improves."

08:29 < mike_storm> zeebo: Oh, that's not threads then. Huh.
08:29 < yorick> what exactly are the differences between gccgo and gcc, what
do I need to rebuild?
08:30 < zeebo-> it is threads.
08:30 < Ycros> mike_storm: it is threads
08:31 < zeebo-> it has n+1 threads when i run the program no matter what n
is
08:31 < Ycros> mike_storm: but you can end up with more threads than
GOMAXPROCS
08:31 < zeebo-> yeah that too
08:31 < Ycros> because any goroutine blocking on an external call will get
pushed onto another thread
08:31 < mike_storm> Yrcros and zeebo: But it seems to set "maximum
processors". As in cores. Not the same as threads.
08:31 < Ycros> mike_storm: yes, but how do you run code on multiple cores
08:32 < mike_storm> yorick: My understanding is that gccgo is a front-end to
gcc. Look into gcc front-ends. Don't know more than that.
08:32 < zeebo-> mike_storm: test it out. i ran the sample sieve program
they gave in the tutorial and changed the value in the function call and looked at
the thread count of the program
08:32 < zeebo-> it spawns threads
08:33 -!- danmarner [n=dan@rrcs-24-227-222-36.sw.biz.rr.com] has joined #go-nuts
08:33 < mike_storm> zeebo: I'm not saying it doesn't. I'm saying that
GOMAXPROCS is independent of the thread count.
08:33 < mike_storm> You can have a lot of cores and few threads, or lots of
unused cores and 1 thread.

08:33 < Ycros> why's everyone going for gccgo, the thing has issues -_-
08:34 < zeebo-> correct. the go runtime will have GOMAXPROCS threads
running for cpu bound goroutines
08:34 < mike_storm> Ycros: Set GOMAXPROCS greater than 1 and let Go do the
rest. I haven't read anything about finer-grained thread control.
08:34 -!- sg [n=sg@83.231.11.70] has quit []
08:34 < yorick> because people already have gcc
08:34 < yorick> less change :)
08:34 < mike_storm> zeebo: I believe that's incorrect. The Go runtime will
have GOMAXPROCS *cores* available to run threads on.
08:34 < mike_storm> You can have a lot of threads running on one core.
08:34 < Ycros> yorick: except you still have to build either compiler
08:34 -!- nahojkap [n=chatzill@yggdrasill.compukos.nl] has quit [Remote closed the

08:35 < zeebo-> i dont have 40 cores
08:35 < mike_storm> zeebo: Did it really do that?
08:35 < Ycros> yorick: and the default compiler is faster and works better
at the moment
08:35 < zeebo-> yes

08:36 < mike_storm> yorick: Considering it was released... yesterday?
08:36 < mike_storm> When was it released? I read about it on /.
08:36 < zeebo-> the go day 3 course says this too: "GOMAXPROCS tells the
runtime scheduler how many non-syscall-blocked goroutines to run at once."
08:36 * yorick thinks today
08:36 < Ycros> yeah
08:37 < zeebo-> and that seems accurate so thats probably the better doc for
it
08:37 < Ycros> zeebo-: the document also mentions that in the future the Go
runtime will self-regulate the number of cores thing
08:37 < zeebo-> right.
08:37 < Ycros> yorick: feel free to try - a mingw or cygwin port would be
better than nothing
08:37 < Ycros> yorick: still, people have been complaining about gccgo, so I
suspect you'll have much trouble down that pat
08:38 < mike_storm> yorick: Seriously, look up how GCC front-ends work on
MinGW and give it a go.
08:38 < mike_storm> Ycros: From what I've heard about GCC internals, I'm not
surprised.

10:06 < JBeshir> Apologies for harping on about this, but now one of the
devs seems to be around... I'm trying to figure if I should leave stuff alone to
be optimised for a while, or keep playing with Go now; is it expected for the
Hello World app (plus a "for true { }" at the end to keep it running) to have an
RSS of ~5684KB on linux/amd64?
10:06 <+danderson> sorry, not a dev, I just work here
10:06 < JBeshir> Ah, okay.
10:06 <+danderson> that said
10:06 <+danderson> I may be able to offer non-authoritative thoughts
10:07 <+danderson> you're using 6g/8g to build this I assume?
10:07 < JBeshir> Yeah.
10:07 < JBeshir> That's the detail I forgot.
10:07 < JBeshir> 6g and 6l.

10:07 <+danderson> okay, so the large binary size is not a feature of the

10:08 <+danderson> the 6* compilers are based on the plan9 compiler
architecture, which can only generate static binaries
10:08 <+danderson> (and references to existing dynamic libs, but no new
dynamic libs)
10:08 < andguent> halleluja for that
10:08 < JBeshir> Hmm, the binary is 'only' 634KB
10:08 < JBeshir> Er, 624KB
10:08 < UKRep547> is it possible to link Go binaries/object files to object
files from other languages?

good part of it might be inefficiencies in the runtime

10:10 < JBeshir> Okay.
10:10 <+danderson> another part could be constant overhead of the runtime,
which looks rather bad on hello world but might be bearable for larger apps
10:10 <+danderson> bottom line, I'm talking out of my ass, and I don't know
:)
10:10 < lotrpy> Snert, It's great
10:10 < JBeshir> Maybe, but that's some constant overhead

11:30 < defectiv> uriel: that's where i'm at in the video.
11:30 < blasdelf> If you want to have some idea of what OO really is, read
the first half of "A Theory of Objects" by Cardelli and Abadi
11:31 < uriel> blasdelf: I fear the battle for the proper deffinition of OO
has been lost long ago
11:31 < blasdelf> Luca Cardelli even wrote CSP languages with Rob Pike at
Bell Labs
11:31 < uriel> blasdelf: indeed http://doc.cat-v.org/bell_labs/squeak/
11:31 < garbeam> uriel: not necessarily
http://en.wikipedia.org/wiki/Object-oriented_programming#Formal_definition
11:31 < dRiZzle> amar, i have it on ubuntu 9.10
11:32 < blasdelf> "A Theory of Objects" takes a different approach,
describing the possibilities and what implements them (and what is untouched)
11:32 < garbeam> uriel: since Go has interfaces that's enough to fulfill the
polymorphism criteria
11:32 < uriel> garbeam: again, nobody uses that definition, and English
words are deffined by usage, not by authority/decree
11:32 < garbeam> uriel: am I nobody? ;)
11:32 < uriel> yes ;P
11:32 < int-e> uriel: there are delegation based approaches as well
(prototype based languages), and there's the whole type based dispatch idea (which
golang seems to subscribe to)
11:32 < Associat0r> garbeam yes
11:32 < blasdelf> I wish Cardelli worked at google -- then Go would have
user-accessible parametric polymorphism
11:33 < uriel> if you take the original deffinition of OO, as rob points in
the presentation, Go is much more OO than java or c++, but nobody remembers that
stuff

and just install again or ... ?
11:35 < uriel> blasdelf: yes! once Go has a gui system, we need to write
something like crabs somehow! ;))
11:35 < garbeam> Let me rephrase: inheritance is one of the main causes for
totally baroque OO design
11:35 < uriel> garbeam: probably the main cause
11:35 < Associat0r> agreed
11:35 < amar> dRiZzle: yeah..did all that and right now installing
again....wait please.....i shall get beack to you as soon as i complete ..success
or failure...
11:36 < uriel> everything else in OO is quite sane, tying up the data
structure design, the type system and the behavior using inheritance just creates
an huge mess

12:45 < Wiebe> I was thinking in the Python / PHP way of OOP..
12:45 < vegai> not even that much
12:46 < vegai> of the languages I know, it reminds me of Haskell's "OOP" the
most
12:46 <+danderson> vegai: that's because Go interfaces are very nearly
Haskell type classes.
12:46 < vegai> the interface inferring is quite nice
12:46 <+danderson> there are a couple of nuances, but they're close cousins

12:47 < ptrb> Can one have multiple packages in the same .go file?
12:48 < ptrb> Specifically, including a main package in a library package
for testing purposes
12:48 <+danderson> vegai: the general idea is not completely new, other
languages in the past have had similar OO setups, and haskell has type classes
today
12:48 <+danderson> but the details of how the object model works are
probably "new"
12:49 < wollw> ptrb: that is what foo_test.go are for
12:49 < vegai> danderson: haskell either doesn't infer instances, though
12:49 < vegai> like go seems to
12:49 < ptrb> wollw: ah yes, I remember reading about that
12:49 < ptrb> thanks
12:50 <+danderson> vegai: right. As I said, cousins, not identical concepts
12:50 < pkrumins> danderson, and who is the artist? thompson? :)
12:50 <+danderson> haskell also has default implementation for type class

12:51 <+danderson> eg. in the haskell type class Eq, == and /= are defined
in terms of each other
12:51 <+danderson> so each implementation of the type class need only
implement one of the two, and it gets the other "for free" if it doesn't need
fancy logic

12:52 < jaxdahl> does ~/go/doc/progs/helloworld3.go compile for you guys?
(make a file called ./file)
12:52 <+danderson> my personal feeling is that automagic matching of
interfaces to objects is much cooler, but both languages are neat in my book.

nothing

14:01 < alus> ptrb: why is immaturity in library support an indication of
design goals?
14:01 < JBeshir> My point with the HTTPD thing was that it was good for
complex (but not essentially vast) applications; sticking an interface on it
doesn't really affect the appropriateness of the language for the role, IMO.
14:02 < alus> syd: boo QT. yay native.
14:02 -!- m-takagi_ is now known as m-takagi
14:02 < eekee> maruel: it's often used directly to build user interfaces, is
it not?
14:02 < Kniht> alus: what?
14:02 < ptrb> alus: immaturity isn't -- but the support that exists in the
language today indicates the designers' (at least initial) concerns
14:02 < syd> native..what? :)
14:02 < syd> and where
14:03 < alus> Kniht: native interface APIs are great. no toolkit I've ever
used has been as easy and flexible to make a real UI
14:03 < Kniht> alus: in other words, "I want to use something other than Qt,
therefore I must use something other than Qt."?
14:03 < saati> alus: native interfaces are by definition not portable
14:03 < saati> Qt runs on everything that has a gui
14:03 < alus> ptrb: sure. I think their concerns are well-placed too. I
don't want a new UI system, just some hooks to call the existing API.
14:03 < alus> Kniht: basically

wrong :p

15:31 < JBeshir> C pointers are dangerous things in a way, so whenever
you're passing them around you need a memory management/pointer validity plan.
15:31 < JBeshir> Go could probably safely use pointers everywhere.
15:31 < alus> pointer validity plan?
15:31 < alus> don't screw up :P
15:31 < MattCampbell> Would Go be a good language for desktop applications?

15:36 < JBeshir> I don't think it has references.
15:37 < Cameron> if I pass a struct value to a function, does it get coppied

15:37 < JBeshir> Yes.
15:37 < Smari> The EBNF parser module ("ebnf") supports loading and
verifying a grammar, but doesn't seem to be able to actually parse input according
to the grammar. Am I misunderstanding something or is this simply not implemented
yet?
15:37 < jaxdahl> what would the equivalent of printf("%d",5) be in

15:39 < JBeshir> WriteString looks to be "plain" I/O, while Printf is for
complex formated I/O, if they follow the typical pattern (not at all guaranteed
with Go)
15:39 < JBeshir> So for jobs actually calling for formatting multiple things
into a string, Printf might be the right tool, while WriteString is useful to just
output a damn string.

16:53 < UKRep547> Thorn, in java, let's say you define two object
"references". A and B. Then you say A = B, all you have is A pointing to B. The
dot (A.method) is the deferencer, and deferencing is an operation you do on
pointers.
16:54 < UKRep547> sorry, I mean A points to what B was pointing to.

16:57 < UKRep547> but foo can = null, Thorn. How is foo a reference?
16:57 < Athas> Is there a collection of simple Go programs (so I can learn
how to deal with command line arguments and file I/O) somewhere?
16:58 < Thorn> UKRep547: if you consider null to be an instance of Foo it is
a reference
16:58 < UKRep547> what? Thorn? Are you seriously saying null is an object?
16:58 < Thorn> and null is an instance of Object which is a superclass of
Foo

17:31 < RadSurfer> Fortunately Delphi out performs VB

17:50 < Zaba> personally I think that things like where a capital letter
should go and where it shouldn't should be mere conventions of the language, of
its community.
17:50 < sstangl> exch: if you've made a design choice that complicates the
language for a certain base of your users, that's an issue of the language.
17:50 < UKRep547> Zaba, I agree with you; it would be nice if it was a
convention, not a restriction
17:50 < exch> true, but is this really that much of an issue?

17:51 < UKRep547> asonge, particularly given how much go has opened the door
to UTF-8 and, in spirit, is designed to be foreigner friendly as much as possible
17:51 < uriel> people using foreign languages in variable names should be
burned at the stake
17:51 < eno> so, what is the syntax for map of string to map of string to
int?
17:51 < Zaba> it's not about extensible, but hey, what if I want _my_ code
to use underscores_between_words rather than camelCase or MixedCase? No dice, I
need 'em capital letters if I want things public...
17:51 < sstangl> asonge: I don't see what that has to do with the merits of

were subtly wrong.

annoying at first but soon realize the advantage of being able to glance at a
piece of code and be able to identify the private and exported pieces

net.Conn has Read(b []byte) (n int, err os.Error) and io.Reader is Read(p []byte)
(n int, err os.Error)
18:13 < Thorn> what would it take to write a Qt adaptation layer for go? is
it even feasible?
18:14 <+iant> Thorn: it is feasible; see misc/cgo for a small example
18:14 < saati> the site mentions an ffi for 6g if i am not mistaken
18:14 < slide_rule> i've been playing around with implementing a binary
search tree in go (just to get familiar), and I've run across some stumbling
blocks. Is there an implementation out there I could peruse?
18:14 <+robpike> dsal: i know what's confusing you. net.Conn is an
interface, not a struct. there's likely no need to take its address/make a
*net.Conn
18:14 < saati> where can i find it's docs?

18:16 < JBeshir> Hmm, so, it's the right time of day to ask now. There's
some mention in the FAQ about the implementation of the runtime of concern for the
footprint. I'm wondering if it's expected at current for it to be a bit over
5600KB using 6g and 6l on linux/amd64, and if so, whether that's planned to be
improved, and if so, whether that's "slight longterm optimisation" or "drastic
optimisation relatively soon".

19:16 < rog> when converting between interface types, or struct to

19:16 < amacleod> uriel, ok.. I'll look there.
19:16 <+robpike> dho: cov and nm can wait although i think gotest needs nm.
gopack cannot, unfortunately
19:16 <+iant> rog: it does do an allocation
19:16 < wcn> What exactly is the runtime cost of a goroutine? The segmented
stack initially starts off how large? If I have thousands of goroutines sitting
on a channel to serialize access to an struct, is this going to cost memory much
larger than the size of the structs themselves?
19:17 < wcn> Clarification: each goroutine sits on its own channel.
19:17 <+iant> rog: I think the time depends on the number of methods in the
interface
19:17 <+robpike> rog: first time a pair of types gets together, a data
structure is built for that pair. after that, it's O(1)

guaranteed to implement all the methods for both interfaces)
19:41 <+iant> braims: type I3 interface { I1; I2; }
19:42 < braims> thank you
19:42 < amacleod> How do I build experimental packages? I tried 'make' and
'make install' in pkg/exp/draw, but neither fixed the "can't find import" error.
19:42 < ambv> iant: I9 interface ;)
19:42 <+iant> amacleod: you might have to use a -I option or move the .a
around or something; the exp Makefiles are not clean, as you've discovered
19:43 < amacleod> Indeed.
19:43 < amacleod> I'll try putting the .a right in exp/draw

install. It put draw.a in exp/draw/_obj

$GOROOT/pkg/$GOOS_$GOARCH
19:44 <+iant> amacleod: you can add -I options to tell 6g/8g to look
elsewhere; -I takes a directory
19:44 < poucet> danderson: are goroutines gc'd if there's no reference to

anyone remember how?
21:04 < adam_godev> Is &string[k] the only illegal use of the '&' operator?
What I had in mind is an array of T (being struct, int, string etc.). So, fill an
array of T to amount k, then get &T[k] and fill another array of pointers to &T[k]
for respective k's. (so long as all k are of the same type)

you also import math. and the math package initializer has a few floating point

22:25 < voxadam> I recently watched Pike's Go presentation at Google on
YouTube. He mentioned that there was work underway (or maybe scheduled) to
replace the current mark-and-sweep GC with something more advanced. Specifically,
he mentioned The Recycler from IBM. IBM claims a maximum pause time of 2.6 ms.
If this is true what are the chances of Go being suitable for
real-time/deterministic programming?
22:25 < nmichaels> Does Go do ada-style array re-bounding and bounds
checking? For example, can I declare a slice with indices 7-12?

etc.
22:58 -!- dchest [n=dchest@81.5.81.249] has joined #go-nuts
22:58 <+robpike> dho: are you grubbing around the runtime code (C) or some
place in Go?
22:59 < only482> i'm guessing i need to read to a byte array?
22:59 < dho> robpike: runtime code, porting to freebsd
22:59 < dho> thr_new wants the size of the stack you're passing it
22:59 <+iant> only482: Read expects a slice
22:59 <+robpike> dho: runtime.h declares the fields in G
23:00 <+robpike> only482: you probably want to wrap os.Stdin using bufio.
there's a version doing this with Stdout and Write in the tutorial. should be
easy to adapt
23:00 < ojm> only482: Here's a demo asking for a letter and printing it
http://pastebin.com/m7cb73c6
23:00 <+robpike> only482: then you can read lines using ReadBytes etc.
23:00 <+robpike> ojm: yes that's the way

23:01 < harryv> hm. a slice can't just have variable length?
23:02 <+iant> harryv: a slice can have variable length but it can't have
variable capacity
23:02 < dho> robpike: Right, but the size would effectively be
G->stackbase - G->stackguard + StackGuard, right?
23:02 < harryv> iant: so, in a struct, how do I specify the capacity?
23:02 < dho> robpike: but StackGuard is in an enum in proc.c
23:02 <+robpike> i think so. that was a long time ago.
23:02 < dho> (so is it cool to move it?)
23:02 <+iant> harryv: the capacity of a slice is defined when you make() it
23:02 <+robpike> dho: if that fixes the problem,, sure
23:02 < dho> okydoke
23:03 < harryv> right.
23:03 <+iant> harryv: so it comes from the struct initializer

23:18 < tunnuz> robpike, I'm taking a look to the go tutorial, I just

23:18 < ni|> the suggested way is to use the plan9 style compiler right
23:18 < ni|> with 6g and 6l as opposed to gccgo
23:19 < chrome> robpike: any reason why this wouldn't work as expected to
remove 2 characters off the end of a byte array and then convert it to a trimmed
string? line = strings.TrimSpace(string(bytes[0 : len(bytes)-2]));
23:19 <+kaib> eno: are you still around?
23:19 < harryv> hm. I can't pass a channel in its own right through a
channel? it has to be encapsulated in a struct?
23:19 < tunnuz> robpike, I'd love to love Go, in the meanwhile tank you
23:19 <+iant> ni|: depends on your goals
23:20 <+iant> harryv: you can pass a channel on a channel
23:20 < jaxdahl> ie, foo chan chan ?
23:20 <+robpike> the two compilers are packaged separately. 6g etc. are
faster at compiling, don't generate quite such good code, have more advanced
runtime. gccgo is slower at compiling (but not bad), generates better code, is a
little behind on runtime but catching up fast. it's up to you
23:20 <+iant> chrome: that looks right to me
23:20 < harryv> foo := make(chan chan); gives syntax error
23:20 < jasom> From the tech-talk slides, it looks like 6g should be
parallel on an SMP machine?
23:20 < ni|> robpike: thanks!
23:20 <+iant> harryv: well, you need to say the full type of the channel, as
in foo := make(chan chan int)
23:20 <+robpike> jasom: 6g is the compiler. it's a c program, doesn't run
in parallel
23:20 < harryv> ah.

01:34 < Eridius> blasdelf: right
01:34 < huntertehawesome> @blup still wont work
01:34 < Eridius> mainman__: because there's too many 32-bit kexts out there,
including some that ship with the OS, so Apple is defaulting the kernel to 32-bit
01:35 < scandal> trying to use this: for _, s := range tags.Data() {
println(s) }
01:35 < Petein> bogen: aha
01:35 < Eridius> they default to 64-bit on the servers because those are far
less likely to need 32-bit kexts
01:35 < Eridius> you can instruct your system to boot the 64-bit kernel
instead by holding down the 6 and 4 keys during startup

02:03 < alus> petercooper: you know I always thought that would be a good
thing to have - even just C/C++. turns out python and ruby are so slow you have
to write all the interesting parts of you app in C/C++, and you're left with a
command line options parser in python
02:03 < petercooper> Once I get a hang on the interface, writing the inliner
is pretty easy (for Ruby, at least).
02:03 < kuroneko> I think the point is that you don't really need Python and
Ruby when you have Go
02:03 < alus> petercooper: that said. Go on Rails, plskthx
02:04 < kuroneko> yeah, I'm thinking Go on Rails too actually :)

05:14 <+iant> &v is a pointer to v
05:14 <+iant> if you say p := &v
05:14 <+iant> then later you can say *p = 1
05:14 <+iant> and that will set v to 1
05:14 <+iant> that's pretty much it
05:14 < KirkMcDonald> If v is an int, then p will be a *int.
05:15 < jchico> anybody already made a syntax highlighter for Go in a text
editor?
05:15 < keeto> yeah, I kinda get the & to return the address and * to get
the value thing.
05:15 <+iant> the main reason to have pointers in a language like Go is that
it lets you pass large values by reference, i.e., efficiently
05:15 < keeto> but why the need for them in go?

05:18 < KirkMcDonald> keeto: Whereas if you say "x = 12" in Python, that

automatically passed as a reference?
05:21 <+iant> well, Go does allow multiple return values
05:21 <+iant> keeto: right
05:21 <+iant> which means that if the function changes a value in the slice,
the caller will see the change after the function returns

06:26 < Quadrescence> Does this channel support 90s karaoke?
06:26 < anticw> iant: well... i should maybe ask why it's the way it is,
clearly you more than most people would understand subtleties here
06:27 <+iant> I haven't done much work on that compiler; a big part of the
way it is is because, as I understand it, it does register allocation on a
statement by statement basis
06:27 <+iant> that is fast but obviously limits optimization
06:27 <+iant> and it means that it's hard for it pass registers in
parameters because it would mean that it has to reserve those registers when
computing the other parameters to pass
06:28 < Quadrescence> Come on, Go team, step up to the power of Aldor or
MLton
06:28 <+iant> that is, after computing the first parameter, where do you put
it, if you aren't doing global register allocation?
06:28 < KirkMcDonald> iant: And this can't be helped by the limited number
of registers on x86.
06:28 < anticw> iant: but all that seems more specific to the 6g
implementation, not something more intrinsic
06:28 <+iant> right, well, on 32-bit x86 stack passing is standard anyhow
06:28 < bogen> yeah, that is why the x86_64 one is more mature I think

06:39 < fgb> anticw, it's also crappy code and header bloat as well
06:40 <+iant> dejones: you can create a closure which refers to variables in

06:40 < Eridius> iant: err yes, that's kind of the definition of a closure

a big difference :)
06:40 < Eridius> iant: Blocks can do that
06:40 < dejones> blasdelf: Ha, definitely. :)
06:40 <+iant> Eridius: my understanding is that they can not refer to
variables in the enclosing function after the enclosing function has returned
06:41 < Eridius> iant: sure they can - the compiler moves those variables
into heap storage when the block is copied
06:41 < blasdelf> iant: unless they are objects
06:41 < bogen> Null-A: hmmm.... ok, I'm confused on that lock/unlock, I

06:41 <+iant> Eridius: can you just return the block?
06:41 <+iant> If so, I am mistaken; sorry
06:41 < Eridius> iant: no, the block is a stack object by default. But you
can return a copied version of the block
06:41 < Eridius> return [myBlock copy]
06:41 < Eridius> or return Block_copy(myBlock)
06:41 <+iant> so similar but not the same
06:42 < bogen> Null-A: Oh, the expression is partially evaluated
06:42 < Eridius> teh copy takes it off the stack, puts it in the heap, and
moves all referenced __block variables into the heap
06:42 <+iant> and are the __block variables in the heap shared with other
closures in the same enclosing function?
06:42 < Null-A> bogen: it has to evaluate the inner arguments of the
function, since, the expression might not be valid during function return
06:42 < bogen> yeah
06:42 < Eridius> iant: yes
06:42 <+iant> ok

06:45 < Eridius> well, it prevents a lot of accidental state-sharing
06:45 < Eridius> having everything be mutable would let you easily shoot
yourself in the foot when using GCD
06:46 <+iant> since I used to use Scheme, I tend to think of the state
sharing as the point
06:46 <+iant> maybe that is just me
06:46 < Eridius> iant: it would be like in Go, having all your goroutines
trying to write to the same map. That's not exactly a good idea
06:46 < kongtomorrow> iant: if the point is to grab a block and throw it
over to another thread to be performed, it's often a snapshot that you want.
06:46 < Null-A> When are you passing mutable data through channels, when are
you not? maps are mutable?
06:47 <+iant> we're still talking about closures, right? If I name a
variable, I want that variable. If I want a copy of that variable, I make a copy
of it. That is just how variables work
06:47 <+iant> to me
06:47 < Eridius> iant: except if you want the variable to be mutable within
the block, this also changes the storage characteristics of the variable in the
function, it's no longer a stack-based object (assuming you copy the block) and
accesses have to go through one layer of indirection
06:47 <+iant> Null-A: maps are mutable, yes, and they can be passed on
channels, yes
06:47 < Eridius> so making them mutable by default has performance
implications
06:48 <+iant> Eridius: What happens in Go is that they move onto the heap if
a closure refers to them, otherwise they stay on the stack
06:48 -!- DeFenderm`n is now known as DeFender|Sleep
06:48 <+iant> this could be better optimized, of course, but currently isn't
06:49 -!- KurtKraut [n=Kurt@unaffiliated/kurtkraut] has joined #go-nuts
06:49 <+iant> the variable only has to be moved on to the heap if the
closure is captured or escapes
06:49 < Eridius> yeah that's what happens with blocks
06:49 < Eridius> but my point is that mutability is usually not required for
the captured variables
06:49 <+iant> sure
06:49 <+iant> it's easy to look at the code and see whether the function
changes the variable
06:50 * Eridius wouldl ike to keep discussing this, but must tank an instance in
WoW now ;)
06:50 <+iant> k
06:50 < Null-A> iant: So can you pass a map by value?
06:50 <+iant> my point is just that people are accustomed to how variables
work, and in Go closures they work in the accustomed way

07:12 < Null-A> *nods*
07:12 < Null-A> Sure on the single-node concurrency, they're pretty
equivilent
07:13 < Null-A> They'd have to change the primitives in a fundamental way to

07:14 < dejones> Null-A: I think you could define the channel type as a
TCPConn or something related.
07:15 < Null-A> ? The channel type is the data being passed around

large software systems
07:44 < dejones> Glao: I suggest reading the link I gave, they can explain
better than I. :)
07:45 < erikc> learning haskell may also make you a better programmer in

07:45 < erikc> certainly made me a better c++ programmer
07:45 < dejones> erikc: Yep! More tools in the toolbox! ;)
07:45 < Null-A> Plus you can use it as a specs language
07:45 < Null-A> or prototyping language
07:45 < Null-A> C++ will never be a prototyping language ^^
07:45 < mkanat> Null-A: Python has types--just not at compile time.
07:45 < Null-A> *nods* I was waiting for some to correct me
07:46 < mkanat> :-)
07:46 < Null-A> Still, compile time type support is a huge aid
07:46 < Jerub> python either has one type, or many, depending on what part
of the type system you're reasoning about.
07:46 < mkanat> Null-A: Agreed.

08:53 < chrome> Much like you can get an awful lot of things done in C right
now, go is trying to build on that by extending the language where it makes sense,
improving the runtime and getting rid of some things that are bad.
08:53 < chrome> the tools are fresh, I totally don't care about performance
right now, I'm more interested in how easily I can get stuff done in it.
08:54 <+danderson> given Go's feature set and general sanity, I'll take a
10-20% hit compared to C, but not the 2-29x hit currently :)
08:54 < JBeshir> danderson: Exactly.
08:54 <+danderson> but as I said, work in progress and all that.
08:54 < hd_> chrome, have you written anything in go yet ?
08:54 < chrome> hd_: yes
08:54 < leadnose> what is the plan on generics? is it going to be included
at some point or is it considered unimportant for this kind of language?
08:54 < JBeshir> leadnose: I think it's kinda being thought on.
08:54 < chrome> hd_: a telnet talker:
http://www.stupendous.net/archives/2009/11/12/google-go/
08:55 <+danderson> leadnose: see the language design faq: both generics and
exceptions are being considered, but they're not quite sure how to get them in
cleanly.
08:55 < chrome> leadnose: rob mentioned generics will be addded at soe
point, but they are still working on the details.
08:55 < mainman__> my hope about go is to have a smarter multi-thread
replacement for my python stuff, instead have to extend in c++ (but that with
boost is quite simple). and also working with pointers is a plus for me.
08:55 < JBeshir> Good exceptions would be nice, but cleanness is a must.

current timelines terminated at the open source release
08:56 <+danderson> they now have to make a plan for the next steps
08:57 < chrome> for me, I've always wanted a few things in C that go does
well; 1) method sets in go, give you a level of OOP without making it overbearing.
2) goroutines simplify concurrency without having to mess with posix threads
manually 3) channels make message passing between threads simple. Its not like
you can't

08:57 < leadnose> somehow it seems that generics would be pretty big thing

08:58 < sfuentes> is there a vim syntax hl for go?
08:58 < KirkMcDonald> I am finding myself missing generic functions.
08:58 <+danderson> leadnose: that's the thing. The Go language designers
have worked hard to keep features orthogonal to each other. Generics complicate
this somewhat.

fine, even though it's GCd.
09:00 < KirkMcDonald> D's templates are probably the strongest part of that

10:26 < JBeshir> The problem is that all the alternatives suck here.
10:26 < uriel> anyway, the issue is addressed on the design faq
10:26 < JBeshir> Explicit checks everywhere for errors are ugly.
10:26 < uriel> JBeshir: not really
10:26 < GeDaMo> Is there a wiki for Go code yet?
10:26 < wollw> http://golang.wikia.com/
10:27 < JBeshir> Yeah, really; five lines of "if" after any one-line
instance of I/O is pretty ugly
10:27 < GeDaMo> THanks :)
10:27 < wollw> other than that I don't know
10:27 < JBeshir> Exception handling requires careful design everywhere and
lets errors which don't need to, crash the whole program, because it's not obvious
which functions may return them.
10:28 < JBeshir> What would be need would be some kind of "call this
function, allowing these exceptions" syntax, so it's obvious and explicit in a
call.
10:28 < GeDaMo> So is 'golang' the official search term?
10:28 < JBeshir> But that'd be horribly long.
10:28 < garbeam> just do classic error handling, Go is not Java

prefer writing something like this regularly to defer errors: if((result =

10:39 < JBeshir> I guess in order to replicate an equivalent exception usage

10:41 < GeDaMo> Have you looked at exp/draw?
10:41 < JBeshir> Which is at least a lot cleaner than C, in which you do
need to figure a way to merge it into the return values at each level.
10:41 < garbeam> nsz: in C yes, then using local goto's depending on the
complexity
10:41 < dpb> alus :)
10:41 < slava> exception handling makes resource cleanup much easier. this
is one of the main benefits
10:41 < JBeshir> slava: Deferred statements are better.

implementation

complicate gaining of the resources and usage.

sense?
12:00 <+danderson> either way, I think the answer is no, although the C
preprocessor could be run on the go source, it's just text substitution. Go
should hopefully make many uses of the preprocessor unnecessary though.

12:13 < jetienne> ok :) so i will answer to myself yes

12:14 <+danderson> alus: dunno, I'm not on the go team, I just remember
answers that the experts give :)
12:15 <+danderson> saati: no idea. llvm was rejected way back when, but I
don't think that the go team would oppose an llvm compiler if one were developed.
12:15 < alus> goclang!
12:15 <+danderson> also, note that gccgo could be set up to use the
experimental llvm backend, and voila! Go frontend, LLVM backend.
12:15 < alus> or what have you
12:15 <+danderson> although that would imply having a complete runtime for
gccgo, which is currently not the case

using it?
13:43 < me___> (lwp_create is what libthread_xu uses here, so i used it. i
don't know the tradeoffs between it and rfork)
13:43 < me___> but if we stuck to rfork, we could share a little code there.
13:44 < me___> also we can probably share our libmach bits.
13:44 < dho> yeah.

13:45 < me___> how does the TLS work on fbsd?
13:45 < dho> definitely more plan 9-ish
13:45 < dho> I don't know how that works with rfork. with thr_new, you pass
it a pointer and size to your tls

i.e. it can observe either write. Ok, maybe my understanding of 'observe' is

18:27 < dmz1> iant, did I get it right that Go does not use intermediate C
source code generation but implements a frontend to gcc ?
18:27 < mbt> ajray, I don't, but if it's public I can use bzr to fetch a
copy.
18:27 < WalterMundt> dmz1: that's one option
18:27 <+iant> dmz1: there are two compilers
18:27 <+iant> dmz1: one is a new frontend to gcc
18:27 <+iant> dmz1: the other is not
18:27 < WalterMundt> dmz1: then there's a completely separate toolchain from

intermediate C code

19:53 < fincher> iant: in particular, I'm curious how it interacts with
separate compilation. If types I write now can match interfaces defined later, it
would seem that the packages with those types must be recompiled if they are to
implement the new interface.

can't attach methods to types defined outside your package.

20:47 < yetifoot> port it to .NET
20:48 < atsampson> diabolix: doing lightweight concurrency on the JVM is a
nontrivial problem...
20:48 < ericfode> i would say .net
20:48 < diabolix> and doing it in x86 assembly isn't?
20:48 < ericfode> but i think that a native port would be good
20:48 < atsampson> yes, it's relatively easy in x86 assembler ;)
20:48 < dho> the concurrency aspects are mostly implemented on top of
existing kernel interfaces.
20:49 < dho> the only reason there's any assembler is to get at the
syscalls.
20:49 < ericfode> yes it is
20:49 < diabolix> oh, so it actually uses something like epoll under the
hood?
20:49 < dho> i think you're confused

, if you really want...
20:59 < alphazero> @iant: perfect. tnx a lot!
20:59 < dho> Snert: any chance i can take a look at your 8c/8l changes?
20:59 < Adraen> you can use wget and create a recursive bash script to
download the source :)
20:59 < Snert> Ain't going to install mercurial / python on my boxes;
already have enough SCM systems
21:00 < mightybyte> iant: That demonstrates the problem. I was wanting to
define my own interface instance on net.IP, so I had to make the synonym, but then
I was hoping it would keep the original String implementation.
21:00 < mightybyte> iant: I guess I can't have my cake and eat it too.
21:00 < Snert> dho: no 8c change; one minor 8l change to recognise openbsd
21:00 <+iant> mightybyte: Oh, I see, yes the original String is lost; we
have considered ways to keep it but right now there is no way
21:00 < engla> Snert: installing something like hg2git is not much different
git-svn depends on svn for example, no idea about hg plugins
21:01 <+iant> mightybyte: your new String method can call the old one by
using a type conversion
21:01 < mightybyte> Ok. Seems like it might be nice to address that in the
future.
21:01 <+iant> yeah, it's an open issue
21:01 < mightybyte> iant: Ok, good point. But it's still unnecessary
boilerplate IMO.
21:01 <+iant> agreed
21:01 < diabolix> so, a goroutine will only get swapped out when
writing/reading a channel? and the context switch logic is designed to prevent
race conditions? or can a context switch happen anytime?
21:01 < me__> dho: when you get a chance, can you post you runtime bits so
far?
21:02 < dho> me__: will do when i get home
21:02 < mightybyte> I think allowing interfaces to be defined on non-local
types would be an alternative way of fixing the problem.
21:02 < me__> awesome, thanks.
21:02 <+iant> diabolix: goroutines only context switch when they block on
something, but you can have multiple goroutines running simultaneously
21:02 < dho> Snert: my 8l changes don't generate something that runs so if i
could take a look at that, could possibly be helpful

never use for anything else. I try to keep my systems free of junk.
21:02 < diabolix> iant, right, but I was talking about the userspace context
switch they do when many are mapped to a single thread.
21:03 < blup> well i could tarball it and send it to you

make some system call, there is no timer, at least not currently

that they stay cooperative.
21:03 < mightybyte> iant: Seems like doing either non-local interface
implementations or interface passthrough for type synonyms would have the same
resultant reduction of boilerplate.
21:04 < diabolix> sounds reasonable, probably reduces overhead. and I'd
imagine some debugging implementation of a schedular could very easily allow you
to debug deadlock.
21:04 < mightybyte> iant: Is one easier to implement than the other?
21:04 < engla> Snert: every git tool for working with hg that I've seen uses
python. but I use none now, and don't know what is available
21:04 <+iant> me__: in general yes but there is the issue of CPU-bound code
blocking everything else from doing anything
21:04 <+iant> mightybyte: interface passthrough for type synonyms is the one
we may implement in the future
21:04 < dho> Snert: you could also just grab another copy and diff -u :P
21:05 <+iant> mightybyte: either is easy to implement, the question is the
effect on the rest of the language

21:33 < diabolix> you know, its not just helpful, its required. someday

gonna need the ability to spawn a real thread for that.
21:33 < atsampson> Ycros: dunno...
21:34 < atsampson> diabolix: provided you have a way of making a call into
the library that uses the blocking syscalls mechanism, you generally don't need to
be able to create a dedicated thread

21:34 < alphazero> @Amaranth: you're right: v :=

21:35 < Amaranth> Ycros: GCD is a globally managed thread queue
21:35 < diabolix> Ycros, afaik, GCD is taken into account in the main
scheduler, but each process has issolated contexts for its own tasks, so the
kernel can easily context switch a long running GCD task.

load, or you intend to make external library calls.

22:36 < ehird> Why doesn't `6g -o /dev/stdout ... | 6l /dev/stdin` work?
22:36 < Gracenotes> interesting.. specification says "Arrays and structs
may not be compared to anything.", but you can compare them to nil
22:37 <+iant> Gracenotes: if you can compare them to nil, that sounds like a
minor bug in the compiler
22:37 < KirkMcDonald> Gracenotes: I would naïvely expect that comparison to
always be false.
22:37 < ehird> It results in:
22:37 < ehird> ??none??: truncated object file: /dev/stdin
22:37 < ehird> mainstart: undefined: main·init
22:37 < ehird> mainstart: undefined: main·main
22:37 < Gracenotes> yes, it should be.. though with pointers to either,
that /would/ seem to be a valid comparison..
22:37 < WalterMundt> is there any documentation of the recommended way to
build Go programs and libraries beyond the scale of the tutorial stuff?

22:39 < ehird> Actually, I don't see why 6l would complain about a truncated
file before reaching EOF, so...
22:39 < ehird> the 6g to /dev/stdout works fine, redirected it to a file and
6l is happy with it — so the issue is getting 6l to read from stdin

23:00 <+iant> ajray1: you could open an issue on it, but don't expect a fix
any time soon
23:01 < Gracenotes> so, it seems the 'type' keyword is nearly anything but a
synonym.
23:01 < ajray1> okay. i wish there were a way to have another compiler,
slightly slower, that would check for those things. (youd only need to use it
when you start getting random stacktraces)
23:01 < Gracenotes> in comparison to true synonymity, it is very fascist
23:01 < Gracenotes> more of an irreversible newtype
23:02 < olegfink> iant, i know i'm beyond annoying, but is there some
(secret) documentation on gc's idea of go's AST? i'm having trouble understanding
go.h's struct Node, and pkg/go/ast doesn't seem close enough. i've already
annoyed Russ to the point when i need another victim. :-)
23:02 <+iant> ajray1: you could try gccgo
23:02 < yaroslav> Hey. Have a question on Go language design. I can see
why exceptions are not thare, but why is there GC if Go designers are aiming for
high execution speed? Aren't GC and exeption two things that slow down OO
programs the most?
23:02 < yaroslav> * there
23:02 <+iant> olegfink: there is no secret documentation. I also find it
rather mystifying

23:03 <+iant> yaroslav: GC is really important for correct multithreaded
programs
23:03 < rbancroft> yaroslav: I think that the gc will operate concurrently
so there should be less of a slowdown

pains involved with using C APIs. One function call followed by an if block,

or being silly when i had a clock channel back when i did something with
libthread...
23:35 < blackmagik> ##cobra only about 5 of us on there avg :)
23:35 < Ibw> Ah, so the real innovation in Go is libraries and dependencies.
I was having trouble understanding what was so different from what's out there
23:35 < KirkMcDonald> This channel is going to catch up to #python, at this
rate.
23:35 < me__> though i'd have liked a chan_broadcast() in addition to a
chansend... perhaps i was Doing It Wrong?

23:36 <+danderson> measuring language popularity by IRC channel size is
rather incorrect
23:36 < Gracenotes> I get the feeling it's different from what's out there
partly because of what's out there
23:36 <+danderson> see the relative sizes of ##c, ##java and #python for
proof
23:36 < Ibw> This is fantastic; lots of opportunity for creating Go bindings
to everything out there
23:36 < Ibw> Gtk comes to mind
23:36 < ilaksh> well, I also think that popularity is not necessarily a good
indicator for merit

23:36 < blackmagik> danderson, i've been bashed for doing that before it to

23:36 < ajray1> Ibw: exactly (i've jumped on Postgres) :-) its exciting
23:36 < Ycros> this channel has a newbie-hose pointed at it at the moment,

23:37 < ilaksh> I am not going to die
23:37 < KirkMcDonald> However, writing Python extensions in Go is not yet
possible.
23:37 < ajray1> it got huge after it was slashdotted
23:37 < Gracenotes> Go obeys the C calling conventions, right?
23:37 <+danderson> blackmagik: not really. It reflects how many IRC users
are interested, but a language community extends way beyond that.

23:41 < xorl> hmm
23:41 < Ibw> thanks for the pointer iant
23:41 < Gracenotes> hm. if the supposed speed keeps up, Go interpreters
could be implemented by compiling on the fly. (with some form of intermediate

editor as good as emacs, then get back to us.
23:48 <+iant> Chandon: well, you can't allocate it in one swoop, you have to
allocate the top level slice and then loop to allocate the inner slices

on the toilet.

23:49 < ilaksh> don't think its that awesome but it works

23:49 < blackmagik> I've been comfy with vim but i only started at about 13

01:35 < ehird> btw, is including the $GOROOT/src/Make.* files in a Makefile
ok?
01:35 < ajray1> can i do inline anonymous byte slices (byte slice literals?)
01:35 < ehird> like just doing "include $(GOROOT)/src/Make.$(GOARCH) \n
include $(GOROOT)/src/Make.cmd" to take advantage of the

Quick "go philosophy" question: What's the "right" way to create type-safe

particular struct. As far as I can tell thus far, my options are to roll my own
MyStructVector by copy/pasting, or to use the generic Vector class and suck it up
that a mis-use can throw an object of a bad type in there. Am

02:16 <+iant> flea__: no, I meant that it has iterators, which you can use
via range
02:16 < dga> On a related note: Is there a best practice yet for how to
write iterable objects where I can easily swap between, e.g., a native Go array, a
Vector, and something else? (Context: I was writing some code that used an array,
and then decided I'd rather not reinvent the wheel, and moved over to Vector, but
then had to abandon my use of the range idiom. Or, at least, thought I did...)
02:16 < ehird> the containers are only type safe because the compiler lets
them be
02:16 <+iant> flea__: one could write those methods, given a comparator
02:16 < ehird> no parametric(sp?) types
02:16 < ehird> apart from built in stuff and maps and the like

complexities, though -- eg, optimized IPC by page-flipping; lots of places where
you have to allocate page-aligned memory; wanting very tight control over when and
where the memory was deallocated. You could certainly use GC more easily in a
microkernel-style OS for things not involved with low-level memory management.

02:33 < KirkMcDonald> Oh. So he did.
02:33 < dga> cmarcelo: if you want to dig further, look at how Microsoft's
Singularity OS is structured (type-safe, garbage collected, language-based).
There were several Java-based OSes that people played with that used GC at various
places, though none ever really went very far. The SPIN OS is a classic one,
based on Modula-3 (which looks a lot like Go in many ways. :), but I don't
remember where they drew the line between GC and explicit manageme
02:33 < Gracenotes> just what is the means to get substrings?
02:33 < JBeshir> Slicing.
02:33 <+iant> diltsman_: there isn't any special support in the current
libraries, you could probably use binary/encoding in some way
02:33 < KirkMcDonald> iant: For now I can stick some "return nil" statements

03:02 < diltsman_> jinho: go/misc/vim/go.vim
03:02 < Gracenotes> I suppose you could make a goroutine and then kill it

again and send you the error
03:04 < antarus> Ibw: the IRC protocol is defined in a number of RFCs (1459,
2810, 2812)

03:04 < JBeshir> Gracenotes: You should.
03:04 < antarus> Getting the changes adopted is always the tough part ;)
03:04 < jA_cOp> I know I can use named fields for composite initialization,
but can I use named parameters when calling functions?
03:04 < Gracenotes> the last one is the most important for clients who are

03:04 < Amaranth> hrm
03:04 < JBeshir> Gracenotes: NOT in this case.
03:04 < jA_cOp> I guess that wouldn't make sense anyway

03:05 < dgnorton> diltsman_, <--vim noob ... what can I do with go.vim?
03:05 < Amaranth> the go binaries should really have the path for GOROOT
compiled into them instead of relying on an environment variable
03:05 < ehird> easy enough to restructure the existing docs into it
03:05 < Ibw> I mean how W3 manages a lot of the www standards, like svg and
html. Is there a single entity in charge of IRC?
03:05 < JBeshir> THe last few are not practically implemented by most IRC
server software, and are largely considered as representing only the viewpoint of
a single network, now a very old network not representing current development.
03:05 < dgnorton> oops
03:05 < JBeshir> Er, two.
03:05 < ehird> and I'm tired of futzing around with the html docs

03:05 < Gracenotes> JBeshir: anyhow, if you are implementing a client, the
most important thing is to look at what servers implement
03:05 < Amaranth> or maybe have a default that is whatever GOROOT was when
you compiled and allow GOROOT to be an override
03:05 < dgnorton> diltsman_, not calling you a noob...calling myself a vim
noob :)
03:05 < JBeshir> The first defines the standard subset (roughly) of IRC.
03:06 < JBeshir> Gracenotes: Right. That's what I'm talking about
03:06 < Gracenotes> JBeshir: which goes beyond the RFCs, does not include
some things from the RFCs, and outright violates them in places

03:07 < Ibw> Amaranth: I think you just solved my problem with that comment
about GOROOT. I hadn't put the GOROOT var into bashrc and was only setting it by
hand in a single bash session, as I didn't realize that the binaries relied on it
03:07 < diltsman_> dgnorton: It is a syntax highlighting file. Copy it to
~/.vim/syntax/go.vim. After that edit your ~/.vimrc file and add "augroup
filetypedetext <newline> au BufNewFile,BufRead *.go setf go <newline>
augroup END"

03:08 < Amaranth> Gracenotes: got anything working yet?
03:08 < wobsite> I can't find anything in the standard packages that will
either read a non []byte value, nor convert one to a uint32. I guess I could
write something with bit shifting, but like I said, that seems rather ugly.
03:08 < diltsman_> dgnorton: Restart vim and whenever you open a .go file it
will apply Go highlighting.
03:08 < Ibw> Gracenotes: actually, I was thinking that it would be
interesting to see an IRC server/client that would allow images to be posted in
the classic imageboard fasion
03:08 < Gracenotes> Amaranth: well, I am mostly learning the language as I
go :) But I've connected to a server, joined a channel, and am receiving messages

03:09 < ehird> Anyone feel like restructuring the Go docs as manpages?
03:09 < ehird> Didn't think so.
03:09 < Gracenotes> antarus: I thought of that as well, but that assumes the
bytes are ASCII values

03:09 < Gracenotes> in reality, there are good old fashioned bytes
03:09 < JBeshir> Ibw: For that, you would need to either break compatibility
with existing IRC servers and clients, or implement it via an opt-in feature.
03:09 < Gracenotes> *they
03:09 < JBeshir> Ibw: In which case, it could be implemented as a module in
existing servers and with client modifications to work with it.

parser and the like

a []byte, not a string.
03:11 < Ibw> actually, no. The way it's implemented now I can change the
filename of GOROOT without having to recompile everything...
03:12 < Amaranth> ehird: pkg-config is awesome man
03:12 < dgnorton> diltsman_, do i have to create ~/.vim or should it already
exist?
03:12 < ehird> Amaranth: Please check in to your nearest mental hospital...
03:12 < JBeshir> Gracenotes: Anyways, big omissions in all those RFCs is the
CTCP command, PREFIX, and NAMESX
03:12 < JBeshir> Er, commands.
03:12 < Gracenotes> I've written IRC clients in 3 other languages, which is
hardly as impressive as an ircd, but I like to try to adapt the abstractions in
the client to the language itself. and in the case of Go, I am definitely still
learning
03:12 < diltsman_> dgnorton: It probably doesn't exist, so you will likely
have to create it.
03:12 < JBeshir> Ah.
03:12 < dgnorton> diltsman_, thanks
03:12 < antarus> wobsite: you will likely have to convert it
03:12 < Gracenotes> oh, yeah, you basically have to have CTCP parsing of
some kind

03:13 < ehird> Amaranth: Congratulations, I didn't even think people were

03:13 < Gracenotes> Ibw: I actually did work on a GUI client in Java with

03:13 < Amaranth> ehird: Well the other choice is for every package to
require env variables :)

PREFIX.
03:16 < Amaranth> ehird: How do I install go to /usr/local or /usr or

04:07 < theshadow> Amaranth: wait... I'm really confused here. I'm trying

05:09 < Gracenotes> that is quite unfortunate, since binary resizing isn't

capability

05:18 < dgnorton> scandal, i thought the same thing earlier but didn't go

05:18 < Ycros> you should be able to explicity set the capacity at the

05:18 < Gracenotes> you can make slices of vectors
05:18 < dgnorton> Gracenotes, how?
05:18 < Gracenotes> but if you don't know the logical size, that won't
provide you too many abstractions
05:18 < Ycros> ie. if you know vaguely how amyn elements you're going to
have
05:19 < Gracenotes> for the generic one, func (p *Vector) Slice(i, j int)
*Vector
05:19 < scandal> Gracenotes: well, i'm talking about in the "go" sense of a
slice where it refers to a portion of some other container
05:19 < Gracenotes> backed by the one whose method you're calling
05:19 < scandal> Slice returns a new Vector by slicing the old one to
extract slice [i:j]. The elements are copied. The original vector is unchanged.
05:19 < scandal> not quite the same thing

05:27 < Gracenotes> you could easily export a (properly implemented) Vector
as an array slice. For the growability itself... not so good
05:27 < quag> Simple, but does http fetch and xml parsing.
05:27 < quag> would have been somewhat more difficult in C :)

05:32 < Gracenotes> uh. sure.
05:32 < Gracenotes> :|
05:32 < me__> dho: that was really fast.

05:32 < dho> me__: it's still not done
05:32 < dho> but it's something
05:32 < Ycros> Gracenotes: the vector could hold weak pointers to all the
slices - so if the vector's internal array gets recreated, you can update all the
slices. But they still get GCd

05:50 < ehird> the _, and the {...}, clearly show this isn't just a simple
assignment involving a variable
05:50 < ehird> *looked more
05:50 < jessta> ehird: it's only in const scope and the behavoiur is obvious
after using it once
05:50 < ehird> yes. it's still ugly
05:51 < Gracenotes> http://golang.org/doc/go_spec.html#Type_assertions <-
from the specs
05:51 < jessta> ehird: if you want enum beahviour you need something that
increments
05:51 < glewis> cd ~/go/doc/progs ; 8g cat.go => "cat.go:8: fatal error:
can't find import: ./file" ... 8g -I. cat.go does the same thing. How to fix?
05:51 -!- diltsman [n=diltsman@64.122.18.77] has quit [Client Quit]
05:52 < jessta> ehird: so you either have a bunch of extra typing where you
increament it manually, which you might forget to do causing weird bugs
05:52 < ehird> jessta: yes, but not something that otherwise acts like a
variable and creeps strangeness into otherwise mundane assignmented
05:52 < ehird> *assignments
05:52 < Gracenotes> one type assertion that is causing people pain is
"arr[i] = v.(string)", where arr is an array of strings, and v is an interface{}
(like void*, exists a. a). There is a possibility for v to be null, which causes
things to throw a builtin exception
05:52 < dho> yeah so
05:52 < dho> i'm happy with this so far
05:52 < ehird> just change the syntax from KB ByteSize = 1<<(10*iota)
to KB ByteSize = 1<<(10*_) and I'd be fine
05:52 < Gracenotes> *nil
05:52 < dho> good night all
05:52 < ehird> even happier with KB ByteSize { 1<<(10*_) }
05:53 < KirkMcDonald> Gracenotes: So check for an error.
05:53 < ehird> oh, of course; generics should be able to restrict the type
they get based on type assertions
05:53 < jessta> ehird: if looks like a function in C and nobody complains
05:53 < ehird> well that solves that problem
05:53 < ehird> jessta: iota() would also be fine ofc
05:53 < Gracenotes> KirkMcDonald: that would be nice, were it not in the
stdlib

05:56 < ehird> jesus christ! well then that's a clear advantage to mine.
05:56 < jessta> it increments with every ; but also you can increment it
05:56 < zeebo-> Gracenotes: yeah the specs didn't really make it clear to me

full before you convert it back

07:45 < KragenSitaker> jabb: so that you can change its size in future
versions of the library. C++ people call the pattern "pImpl".
07:45 < glewis_> invalid operation: newGoal % prime (type uint64 % int) ...
how do I cast 'prime' to uint64 ? I've read through the docs... am I missing a
document somewhere that covers this?
07:45 < KragenSitaker> ehird: I think that is the opposite problem
07:46 < KragenSitaker> glewis_: maybe uint64(prime)?

btw

08:43 < KragenSitaker> ehird: a really simple approach would read into
successive 4096-byte buffers in a linked list until you ran out of input, then
allocate another buffer of the right size to copy them into, copy them into it,
and then make a string out of it
08:44 < Gracenotes> that's the last step
08:44 < ehird> KragenSitaker: think that's what gracenotes is proposing

08:44 < ehird> Gracenotes: why
08:44 < ehird> you access it in order

08:45 < KragenSitaker> avoiding reallocation isn't that important or
feasible I think
08:45 < Gracenotes> you could do linked list if you like. the
cache-friendliness you sacrifice probably doesn't matter, since you need it much
more for copying the strings than iterating through the collection
08:45 < Gracenotes> jb55: not quite asynchronous, but you can make a
goroutine that does the same, right :)
08:45 < KragenSitaker> if you had strallocs, you could read into a stralloc
instead
08:46 < Gracenotes> the more temporal chans people are passing around, the
better surely
08:46 < KragenSitaker> temporary chans?
08:46 < jb55> Gracenotes: the api call launches a goroutine and returns a

08:51 < ehird> KragenSitaker: perhaps
08:52 < Gracenotes> I'm still trying to figure out if it's possible to
implement timeout for a chan call. the only thing I can think of is making a
goroutine on the fly to pass a poison pill (maybe nil). actually sounds pretty
good.
08:52 < KragenSitaker> surely they will be replaced with exceptions in Go
2.0 ;)

means it's hard to write a generic send-timeout goroutine, doesn't it?

until one comes up with a value?
08:54 < KragenSitaker> Gracenotes: I do not believe select busy-loops
08:54 < Gracenotes> KragenSitaker: perhaps, but I don't need a generic one
here, with my function addEventCheckTimeout :)
08:54 < KragenSitaker> but I haven't tested it
08:54 < Gracenotes> KragenSitaker: so it peruses all values simultaneously?

that it checks to see if any channel is readable, and if none are, it enqueues the

the scheduler

09:43 < ehird> I would choose C.
09:43 < KragenSitaker> I don't think there really are any other choices
other than those two.
09:44 < KragenSitaker> I mean, what? Forth? Delphi? FORTRAN?

11:41 < olegfink> then it becomes somewhat like (syntactically, but maybe
ideologically too) akin to a static class method in oop

11:43 < oklofok> wait why can you now call it as bufio.ReadByte()?

15:34 <+iant> thanks for contributing, by the way
15:37 < MvdS> I think I forgot to do "hg gofmt", it gives a warning, what
should I do about it?
15:37 <+iant> hg gofmt gives a warning?
15:37 < MvdS> http://codereview.appspot.com/152141 < here it is by the
way
15:37 < MvdS> ne
15:37 < MvdS> *no
15:38 < MvdS> it printed "warning: gofmt needs to format these files (run hg
gofmt):"
15:38 < MvdS> when I did "hg gofmt", it printed the file paths
15:38 <+iant> now run hg upload 152141
15:38 <+iant> to upload the modified files
15:38 < engla> iant: yes exactly, and that doesn't work, I already tried.
the error I found (previously mentioned) is this: "-fsplit-stack" is not supported
by this compiler configuration (whew took a while to find)
15:39 <+iant> engla: ah, sorry, that is a problem
15:39 <+iant> engla: I don't know what to recommend except the bootstrap
15:39 < engla> problem is that it seems to automatically re-bootstrap all
the time
15:39 <+iant> engla: once your system is stable, the bootstrap won't rebuild
the first two stages
15:39 <+iant> I'm not sure why that would happen if you don't rerun
configure
15:39 < engla> go is designed to solve this madness of course, I don't know
what it would do to these overnicht compile times

15:40 < engla> ok
15:40 <+iant> that is, it will invoke make on stage 1 and stage 2, but it
shouldn't actually build anything
15:40 <+iant> a bootstrap takes about 30 minutes on my system, it speeds up
a lot if you use "make -j2"
15:40 < engla> thank you for your input
15:41 < MvdS> How can I see what hg gofmt changed? Looking at the code, I
don't see any changes
15:41 <+iant> MvdS: I don't know, unless you saved a copy of the old file
15:41 <+iant> it may have just changed spaces to tabs, or something like
that
15:41 < Jooon> on http://codereview.appspot.com/152141 there is a delta from

17:05 < Gracenotes> that is annoying, that there are no unbounded chans

17:09 < Gracenotes> even a linked chan would be good. unbounded means, if I
am receiving events asynchronously, I don't have to worry liveness bugs, and
people receiving them in time in the case of a period of rapidfire receiving
17:09 <+danderson> in a pathological case, with bounded channels, your
program will deadlock. With unbounded channels, your program will consume all
available memory and then crash. Which is best?

17:10 <+iant> Gracenotes: a bounded channel doesn't drop messages, it just
blocks the sender when the channel is full
17:10 <+danderson> for a systems language, I think that it's best to remain
in control of the resources consumed by the program, at the expense of being
responsible for allocating correctly.
17:10 < Gracenotes> so I see the value of having a limit -- namely, to avoid
cases where someone tells me to fill up a chan and then forgets about it -- but
putting a hard numerical limit, such that I have to allow a certain percentage of
liveness bugs, is not really a position I want to be in
17:10 <+danderson> (that said, iant is more authoritative here, since he's
actually on the go team, as opposed to being just a random observer)
17:10 <+iant> danderson: I agree with you
17:10 < Gracenotes> iant: that is not acceptable behavior in my case

17:11 <+danderson> hmm, I appear to be unable to devoice myself. That

17:12 < Gracenotes> perhaps I should clarify what I mean by acceptable
behavior. in this case, blocking isn't :) Because I am receiving events from a
networking and dispatching them to a list of chans, all of which need it to
operate okay

17:12 < Gracenotes> I am aware, kirk
17:12 < Gracenotes> oh. lol, sorry. damn scrolling :P
17:13 <+danderson> Gracenotes: so, all your channels have locked up and
you're trying to dispatch more. In your opinion, what should happen?
17:13 <+danderson> I see three options: block until channel is available,
consume all memory and crash, or fail-fast and return an error from the channel
send operation
17:13 < clip9> maybe a way to check and see if a buffered chan is full?
17:14 < Gracenotes> you can do that via ok-checking
17:14 < Gracenotes> and non-blocking receive
17:14 < clip9> ok
17:14 < conra> i looking for polish person ;)
17:15 < Gracenotes> danderson: anyway, that is the problem I'm faced with
with bounded chans. Perhaps I should clarify my situation more: events are going
to be received, and they need to be dispatched pronto, before the next one comes.
if any blocking happens, it happens in the chans that receive the network event.
17:15 < diltsman_> I'm not finding any consistency on Google about where to

17:15 <+iant> rajeshsr: no, no implicit conversions
17:16 < rajeshsr> iant, > int(val[i]) - '0'
17:16 < rajeshsr> how that wpuld work, then?

17:16 < diltsman_> iant: I found them in the misc directory, I'm more
worried where to put them to get them to do any good.
17:16 < Gracenotes> danderson, iant: so if one of those receptive chans is
irresponsible and takes too long to do something (I'm handing them out at will), I
can't let it hold up everything. at the same time, its correctness depends on
receiving every single event. The specific bounding I have to give a chan
provides some protection against this, but it is very unquantifiable
17:16 <+iant> diltsman_: oh, sorry, I don't know
17:16 < rajeshsr> '0' is uint8 type, if am not wrong
17:16 <+iant> rajeshsr: constants are untyped
17:17 <+iant> rajeshsr: see pkg/strconv to convert string to integer
17:17 < rajeshsr> so '0' is inferred to be int in this case?
17:17 <+iant> rajeshsr: essentially, yes
17:17 < rajeshsr> wow, lots of beautiful consequences!
17:17 < Shihan> grace, why not just create a go routine for the send
operation...?
17:17 < Gracenotes> so it's possible that for a 50-length queue, I can avoid
95% of incorrectness bugs. or for 100-length queue, 99.9% of incorrectness bugs.
there is always some amount, though.. eh. I suppose I'll just do non-blocking
add

17:18 <+danderson> Gracenotes: I'm confused. It seems you'd like to assume
a perfect world with infinite memory where everything always works even when it
doesn't. Assume that the channel receiver has deadlocked for some reason. Maybe
temporarily, maybe permanently. What should happen?
17:18 < Gracenotes> Shihan: I thought about that. at least *that* can grow
unbounded.. but it's not like you wouldn't run into the same memory problems as
if you had unbounded queues, in the case of an irresponsible receptor
17:18 < rajeshsr> val[i] has type uint8, right? or is it variable because
of unicode?
17:19 < rajeshsr> val is a string
17:19 < Gracenotes> strings are always bytestrings
17:19 < rajeshsr> oh, ok
17:19 < rajeshsr> so, how then unicode comes for strings?
17:20 < soul9> what about doing duplex chans and negociating wether the
receiver can receive or not?
17:20 < Shihan> i could have sworn i read somewhere if a channel operation
would block, you can do something like "if ch <- data ..." and rather then
blocking it continues on if the operation would block... but i cant find that now
17:20 < Gracenotes> danderson: if the memory runs out, it's the receiver's
fault.

17:21 <+danderson> the ideal solution imho is to fail-fast and return a

17:21 <+danderson> but that assumes you've allocated the channel buffer with
enough headroom to compensate for temporary blockage.
17:21 < Shihan> oh right... yes, that was the one
17:21 < Gracenotes> a channel send error is basically equivalent to program

18:02 < exch> go is pretty cautious about unused resources
18:03 < dga> the rationale I heard for it is that it helps avoid accidents
with := and mistyped variable names on the left.

20:37 < exch> or any value for that matter. it gives that error with ints,

20:37 < me__> write a simulator for one, perhaps a thread per car entering
the circle?
20:37 < clip9> rajeshsr: why? the protocol is public

20:38 < XniX23> someone should write a in-depth tutorial :P to get people
coding stuff
20:39 < MarkAtwood> because the mysql wire protocol is fundamentally broken,
and as many opportunities for improvelment. since drizzle has no commitment to
backward compatability with mysql, we decided this was a good time to design a new

- how do you know what's bigger?
20:55 < steampunkey> If it's unproven.
20:55 < KirkMcDonald> steampunkey: "Bigger" in the sense of the size of the
language.
20:56 < KirkMcDonald> steampunkey: Not the number of people using it.
20:56 < scandal> and concepts
20:56 < steampunkey> KirkMcDonald: define size.

20:56 < steampunkey> i can't believe someone would say something like that
before anyone ever started programming in it.
20:56 < conra> err: if u have teste.8: in console: ./8.out
20:56 < KirkMcDonald> steampunkey: It is a fairly nebulous concept. But the
fact that C++ is more or less a superset of C would imply that C++ is larger than
C.

21:03 < KirkMcDonald> steampunkey: This is not what he is talking about.
21:03 < clip9> No it's not. I've seen the video he is talking about
complexity.
21:03 < steampunkey> KirkMcDonald: If that's the case, he's a poor speaker.
21:04 < huf> or maybe you fail at understanding
21:04 < soul9> steampunkey: no it isn't, your english skills are
insignificant i'd say. A colon separates thoughts usually, except if there is a
backreference, like here to your english skills.
21:04 < xorl> KirkMcDonald: cause, for instance change that useradd remove
the -m and change -m to 'test' and replace useradd with /bin/echo
21:04 < huf> as we had no problems with the video at all :)

about significance.

time than to explain c++.
21:15 < xorl> Since it's treating them as args passed directly to?
21:15 < no_mind> is it possible to wrap a C++ library in go ?
21:15 < tuples_> engla: I think I understand. I will look in that
direction, thanks!

21:15 < nickjohnson> From the tutorial: "There is also a byte synonym for

21:15 < scandal> no_mind: it doesn't appear so. somewhere it's mentioned

21:16 < nickjohnson> Does that mean that strings in Go are byte strings, not
unicode strings? ;/
21:16 < KirkMcDonald> xorl: So of course it can do switches.
21:16 < xorl> hmm

use non-ambiguous words if you can. it'll take some effort, but I'd appreciate
it.

get ints, not bytes

21:19 < bigmac> many thanks
21:19 < steampunkey> KirkMcDonald: ok, but "complexity" is still ambiguous.
21:19 < nickjohnson> But there's no reason it couldn't be stored internally
in, say, UTF-16
21:20 < KirkMcDonald> steampunkey: That's fine.
21:20 < steampunkey> KirkMcDonald: that's what I'm asking then. How is it
less complex than C?
21:20 < JBeshir> nickjohnson: Except efficiency.
21:20 < steampunkey> sry. c++
21:20 < clip9> steampunkey: Go has more core concepts (interfaces, slices,
built-in concurrency stuff, etc) than C while C++ has more (friend classes, lol).
Thats my understandig of what he is saying.
21:20 < engla> rajeshsr: no, you can't index unicode chars in UTF-8. But
you can resync and find character boundaries even in the middle of a byte stream
21:20 < JBeshir> nickjohnson: UTF-16 doesn't make it more efficient.
21:20 < nickjohnson> engla: Unless you mean PYthon 3, I'd go further and say
.NET and Java's approach is better - no implicit conversions at all.

21:20 < nickjohnson> JBeshir: Admittedly you do have to deal with codepoints
>64k, yes
21:20 < rajeshsr> nickjohnson, well, python seems to handle it well by
separating representation and making unicode more abstract. May be Go has
something like that?
21:21 < JBeshir> Personally, I think the way Go does it is good.
21:21 < wollw> steampunkey: I took it to mean something along the lines of C
being less confusing than Go and Go being less confusing than C++.

21:25 < xorl> KirkMcDonald: still get the same result.
21:25 < engla> rajeshsr: since the string's internal storage is []byte..
21:25 < nickjohnson> Having your stored string change because the thing that
passed it in mutated it is problematic. As is trying to use something mutable as
a dict key
21:25 < nsz> i like immutable strings, but i like mutable ones better :)
21:25 < nickjohnson> rajeshsr: I think the preferred way is to accumulate a

22:19 < groceryheist> @fracture good question
22:20 < groceryheist> I don't know.
22:21 < dho> mmmm
22:21 < dga> Answer: Sprint is hideously slow. Extracting the putint() code
from fmt and calling it directly, including the string alloc, reduces the runtime
of that program by a factor of almost five.
22:21 < fracture> lang spec says it is an "unordered collection", which
suggests if it is an rb tree they aren't exposing that to the user as part of the
language....
22:21 * trost saw an interview saying their based on hash tables ;(
22:22 < trost> s/their/they're/ :p
22:22 < Ibw> hmm, do you think naming a Go downloading tool wget would be a
bad idea?
22:22 < fracture> Hm.
22:22 < trost> "goget" is a much better name
22:22 < fracture> can you change the hash function?
22:22 < sladegen> wgot
22:22 < Ibw> heh
22:22 < FxChiP> Why "wget"? :P
22:22 * trost suggests radix trees
22:22 < Ibw> web-get, it's short so it's easy to repeat over and over as a
package name, and there is a GNU command line tool called wget
22:23 < FxChiP> ah
22:23 < Ibw> the last point is the reason I think it may be a bad idea
22:23 < huf> yep
22:23 < nsz> plan 9 calls it hget (http get)
22:23 < trost> nearly as bad as naming a language Go when there's already a
Go! language that's been around for a decade
22:24 < Ibw> does hget support ftp?

itself to primitive types like string/int/bytes or are structs and/or pointers
also possible?
00:31 < bthomson> well go has GOTO but not exceptions
00:31 < uriel> exch: you can send pretty much anything, including channels
00:32 < exch> hmm cool
00:32 < uriel> structs and pointers can certainly be sent over channels too
00:32 < exch> was worried there for a second I had to build elaborate
serialization mechanisms
00:32 < Ycros> channels are awesome.
00:32 < Ycros> I like how the for loop's range keyword operates on a channel
00:32 < uriel> sending channels over channels can be really useful in some

that there are several popular implementations that still stack the main language

02:29 < jeffhill> limec0c0nut: the bug is that members that take a T* this

02:31 < limec0c0nut> jeffhill: My understanding is that's by design. You
defined a T* as a receiver, not a T. Therefore you can call (*T).func() but not
(T).func().

02:32 < hagna> maybe crypto
02:32 < limec0c0nut> jeffhill: Let me find it in the spec.
02:33 < jeffhill> limecoconut: Nope. Defining *T as the receiver lets you
call the method via a T or a *T. Same for defining T as the receiver. This is
what 6g actually does today, it's just the reflection disagrees.

02:38 < jeffhill> limec0c0nut: Please do, let me know what you find. I've
tested it, but I've only been hacking with Go for a day and any guidance is
helpful.
02:38 < __mikem> I am looking at the instructions right now, and they are
not that obvious
02:38 < __mikem> http://golang.org/doc/install.html#tmp_57
02:39 < Ibw> __mikem: They are the same for mac
02:39 < jeffhill> __mikem: There's no .pkg or disk image, if that's what
you're looking for. You need to build from source.
02:40 < __mikem> jeffhill: i am not looking for .pkg or disk images. I am
looking for the .tar.gz file or a source control check out url
02:40 < chupish> are you reading the doc?
02:40 < hans_stimer> when you declare var a [10]int you don't need an
initializer but you still have values so why does a := 10[int] require it?
02:40 < chupish> hg clone -r release https://go.googlecode.com/hg/ $GOROOT
02:40 < s_mosher> hans_stimer, it's a subtle nuance with the way automatic
declarations are done, basically you have have to imply the actual data (even if
it's empty)... you don't need to do it if you declare it explicitly (var a =
[10]int)
02:41 < s_mosher> := is basically saying declare a type for the data I'm
giving you where [10]int is lacking any hint at the data
02:41 < jeffhill> __mikem: The hard part for me there (I'm on a Macbook Pro)
was getting Mercurial installed. http://mercurial.selenic.com/wiki/Download

02:42 < Eridius> bogen: nLines can't be a variable
02:42 < chupish> you need Python 2.6
02:42 < Eridius> bogen: the size of the array is part of its type
02:42 < bogen> Eridius: ok
02:42 < bogen> hmm
02:42 < jeffhill> __mikem: Yeah, it's the source control they use. Once you
get that working, it should be cake.
02:42 < hans_stimer> hmmm.... a := int[10] seems like a pretty strong hint
02:42 < bogen> yeah
02:43 < scandal> hans_stimer: [10]int is a type, not a literal.

03:19 < __mikem> wow, quietgcc aint so quiet
03:19 < Rob_Russell> s_mosher, jlouis: but in general, i think there's an
issue there... i had to look at the constants and decide what the compiler would
do with them
03:19 < __mikem> by the way is go self hosting yet?
03:19 <+kaib_> evening everyone
03:19 < jlouis> Rob_Russell: a constant is of boolean, integer, fp or string
type

03:20 < Rob_Russell> s_mosher: hehe, it's not the looking at that bothers
me, it's the figuring out (since const doesn't need the type specified)
03:20 < jeffhill> limec0c0nut: I've been digging around in the language
spec, but I'm not seeing anything about T and *T vs. interfaces, other than T and
*T are interchangeable for method invocation purposes.
03:21 < limec0c0nut> jeffhill: Well I guess my last statement about the
reflection package was wrong. But please see the reply to your patch.
03:21 < Rob_Russell> jlouis: yeah, "Constants may be typed or untyped" so
the type could be specified where the const is declared
03:21 < jlouis> Rob_Russell: there is a silent coercion that is happening.
03:21 < limec0c0nut> jeffhill: Yeah, I wish it were better-documented too.
03:21 < jlouis> basically, it will fail if your int is not big enough to
contain the value
03:22 < Rob_Russell> jlouis: right, exactly my issue
03:22 < jlouis> and since it is constant I expect it to figure it out
staticly at compile time
03:22 < s_mosher> Rob_Russell, ah. well it's the same thing with := and the
like. you'll see a bit of that. once you're familiar with which types are which
it won't take much figuring
03:22 < jlouis> statically even
03:22 < __mikem> I guess "0 known bugs; 0 unexpected bugs" is a good thing?
03:22 < limec0c0nut> jeffhill: Their theory is that method invocation is a
special case, so that part is explicitly stated.
03:22 < limec0c0nut> jeffhill: Otherwise normal typing rules apply.
03:23 < Rob_Russell> s_mosher: no, i mean, i knew from looking at it that
these consts will be ints. the issue is more about the generalized case
03:23 < s_mosher> Rob_Russell, think of them as macros and you'll be fine,
more or less
03:23 < __mikem> jeffhill: okay, am I done yet or is there more i have to
do?
03:23 < s_mosher> func foo(bar int) {}; will take foo(404); just fine
03:24 < Rob_Russell> right, it's all compile-time, so at least it's
determineable (the error message even tells the type of the const)

03:24 < __mikem> thanks for your help
03:25 < Rob_Russell> just seems that it should be possible to tell the

declaration - that would protect the function declration code from changes to the
const declaration

03:25 < Rob_Russell> jlouis: i like the not needing to declare a type on the

03:26 < jeffhill> __mikem: I had problems even trying D. I clearly have

03:26 < jlouis> Rob_Russell: yeah. But the type system of Go is pretty weak
03:26 < __mikem> jeffhill: you had trouble with D?
03:26 < jlouis> it is almost non-existant
03:26 < ajray> how do i remove a leading ':' character from a string neatly?
03:26 < __mikem> which compiler were you using, the Mars one or gcd?
03:26 < s_mosher> Rob_Russell, but if you did that, then how would you
handle this mystery type in the future? how would you know what you could pass it
to inside your function?
03:27 < ajray> i could cast it to a []byte and index into that and then cast
it back to string
03:27 < s_mosher> I think the implicit conversion there saves a lot more
trouble
03:27 < s_mosher> accept an int, it looks like an int, you know what you
have -- you're good
03:27 < jlouis> s_mosher: it is no problem if you have general type
inference, but that is probably going to be against the "fast compilation" idea.
03:27 < Rob_Russell> s_mosher: well in this case it's the consts defined in
http. in C++ i'd use an enum and the name of that enum would be the type of my
function parameter
03:27 < jeffhill> __mikem: I couldn't figure out how to install it when I

03:28 < s_mosher> jlouis, I actually *like* being beaten over the head with
types. I mean, so long as there's an out. void pointers or interfaces or
whatever.
03:29 < jeffhill> __mikem: Yeah, my problem is that when I hack on stuff,
I'm on MacOS.
03:29 < __mikem> jeffhill: yeah, it might be in macports or fink though
03:29 < uriel> btw, anyone has packaged go for debian yet?
03:29 < limec0c0nut> jlouis: Weak types? What do you mean? I think it's
very strongly typed.
03:30 < jeffhill> __mikem: No doubt, I just couldn't be bothered at the
time.
03:30 < uriel> (I think somebody did add Go to macports)
03:30 < s_mosher> Rob_Russell, gotcha. That's alright, but unless you
already know what that enum is (e.g. that it is an enum) you still don't know how
to work with it.
03:30 < limec0c0nut> jlouis: For one, no implicit conversions, even between
ints.
03:30 < JBeshir> Go is strongly typed.
03:30 < jlouis> limec0c0nut: it is strongly typed. I should have used puny
instead of weak. Sorry.

safety.

03:30 < Rob_Russell> s_mosher: that's true
03:31 < limec0c0nut> jlouis: You always have to either convert an object or
make a type assertion before using it as anything other than its static type.
03:31 < limec0c0nut> jlouis: That's more strongly typed than any language
I've personally used.
03:31 < reubens> if i do 'func (self * myType) function {}', can i only
operate on things allocated with 'new'? but 'func (self myType) function{}' works
with both 'new' and 'var' allocation?
03:32 < jlouis> limec0c0nut: I mean puny here because it lacks almost
everything type theory has added the last, say 30 years or so.
03:32 < KirkMcDonald> reubens: It has nothing to do with how it was
allocated.
03:32 < limec0c0nut> jlouis: Please elaborate.

the object itself/

03:33 < JBeshir> Oh, high level types?
03:33 < jlouis> that is, recursive sum types, e.g. recursive types of
tagged unions
03:33 < reubens> kirk, when i do func (self myType) it seems to work if i
have a pointer
03:33 < JBeshir> Why would you need that in an imperative programming
language?
03:34 < ajray> string(strings.Bytes(wd[1])[1:len(wd[1])])
03:34 < KirkMcDonald> reubens: Yes, the method set of *T includes the method
set of T.
03:34 < JBeshir> Lazy evaluation is "cool", but not at all explicit.
03:34 < limec0c0nut> jlouis: I agree with JBeshir. This isn't a functional
language.
03:34 < ajray> is there a better way to remove the leading character of
wd[1] than that?
03:34 < jlouis> JBeshir: to make the JSON library nice for instance.
03:34 < jlouis> Right now, it looks like a kludge
03:34 < limec0c0nut> jlouis: That would mean run-time evaluation of the type
of an object.

03:36 < jlouis> limec0c0nut: http://golang.org/src/pkg/json/generic.go#L197
03:36 < jeffhill> limec0c0nut: The magic reason why having T not inherit *T
methods for interface reasons is that a T is conceptually const with respect to
methods, while a *T is non-const. Having a T "decay" into a *T interface leads to
badness. That's the essence of rsc's explanation.
03:37 < jlouis> That is the Equal method. It switches on a.Kind()
03:37 < jlouis> it could have been a pattern match instead

03:38 < jlouis> select is almost equivalent, but it is substantially harder
03:39 < jlouis> you could match directly on what comes out of a select
03:39 < jlouis> out of a channel in a select, even
03:39 < jlouis> the select also sorely misses a NACK
03:39 < JBeshir> NACK?
03:39 < jlouis> and a channel mapper
03:39 < jlouis> Look up Concurrent ML.. This was done in the 90'es
03:40 < limec0c0nut> jlouis: NACK as in Not ACKknowledged?
03:40 < jlouis> JBeshir: cleanup if a given channel is NOT the one that is
selected
03:40 < jlouis> otherwise you need to have each case in the select take care
of that with code duplication to follow
03:41 < JBeshir> Or have it after the select?
03:41 < jlouis> then you do not know what channel was selected
03:41 < JBeshir> You can record it.
03:41 < jlouis> and it might be chan-specific
03:41 < JBeshir> With a variable 'n all.
03:41 < jlouis> yeah, it still hurts to switch on that
03:42 < jlouis> anyway, the reason all this is left out is because it is a
bitch to get right
03:42 < limec0c0nut> So basically ML has sort of a combination of switch and
select, and Go separates them.
03:42 < limec0c0nut> But select is still a demultiplexer, not a
pattern-matcher.
03:42 < jlouis> limec0c0nut: no, Erlang has it basically as the same thing.
But it has a dynamic type system, so it can do that.

is bound to a case in the select. It gets executed if another channel is chosen

04:01 < Amaranth> __mikem: although I'd say it's an interpreter for a crappy

04:48 < esm> *Nod* The problem is a bare break inside a switch, inside a

loop, you need a label.

05:05 < timmcd> so you can use Any for pseudo dynamic-typing?
05:05 < timmcd> well, maybe not so pseudo ;)
05:05 < scandal> well, its more like a safe array of void*
05:05 < Ycros> "safe"
05:05 < timmcd> safe array of void?
05:06 < timmcd> (not a c/c++ user, so you may need to explain)

library
05:06 < Gracenotes> often at times when parametric polymorphism would be

05:06 < scandal> timmcd: in Go you have to do a type assertion on soemthing
that is an interface{} to actually use it

05:08 < timmcd> scandal: Basically what I used to do in Ruby ;)
05:08 < timmcd> lol
05:08 < jeffhill> Style question: The language forbids declaring two
functions with the same name in the same package. However, it seems like you can
declare a method version of a function and a non-method version in the same
package and the compiler is happy. Is this bad form?
05:08 < Gracenotes> scandal: yep. I still strongly agree with what Pike
said in the tech talk, that it shouldn't be rushed out -- it should be implemented
carefully
05:08 < scandal> timmcd: i'm not familiar with ruby (i use python), but i'm
guessing you don't need to convert the elements, you can just try to call a method
on it?
05:09 < Gracenotes> jeffhill: if you take the C++ analogy, it's like
declaring an int foo() in a class, and an int foo() outside of it. the class call
will always require an object of that class, so there's no ambiguity. afaik the
analogy holds for Go
05:09 < jeffhill> scandal: Ruby and Python have basically the same object
model, from what I recall. They're both "duck typing".

05:09 < Gracenotes> jeffhill: of course, the ethics of Go seems to be
avoiding name overloading in /any/ form, but YMMV
05:10 < scandal> so in python if you have a list of some objects, you can
just do: [x.method() for x in some_list]
05:10 < Gracenotes> >_>
05:10 < scandal> whereas in Go, you have to use a type assertino prior to
calling a method
05:10 < timmcd> scandal: Yeah, basically I was saying that in Ruby, you can
do a:
05:10 < timmcd> def something(this, that)
05:10 < timmcd> …
05:10 < timmcd> end
05:10 < timmcd> You can use this/that, but you don't REALLY know what it is

know whats going to be passed to it (if everything goes right) ;)

My guess is that it's best avoided for clarity.

is that, unlike C++, 6g requires dependencies to be built before you can compile

07:25 < NickPresta> KragenSitaker: thanks for that catch. scandal: thanks.
That makes things much easier to deal with (and look at).
07:25 < scandal> oh wait, i see what you mean. that should just be return;

07:28 < LinuxMercedes_> xed: looks like it
07:28 < NickPresta> KragenSitaker: :-)
07:28 < xed> LM: I think, if I'm reading it right, it simply cant decrypt
the thing it encrypted to test that functionality.
07:28 < scandal> NickPresta: since you have named return parameters in
shortenURL there are a few chanegs you can make
07:28 < KragenSitaker> NickPresta: you might also want to print the error
message to stderr instead of stdout
07:28 < jeffhill> Ok, so I've got a .go file that will scan .go files and
kick out .d files with the appropriate dependencies, assuming you always use
file-relative includes for project imports (e.g. import "./foo" ).
07:28 < LinuxMercedes_> xed: from my limited knowledge of crypto that's what
it looks like
07:29 < scandal> NickPresta: on line 38 you can just say: return;
07:29 < xed> LM: All I can think of is permissions problems maybe. Don't
know.
07:29 < scandal> except that you should use err instead of error so you
assign to the return var
07:29 < KragenSitaker> jeffhill: that is awesome
07:29 < KragenSitaker> scandal: only if he assigns to shortURL first
07:29 < LinuxMercedes_> xed: hmm what kind of permissions problem?
07:29 < scandal> KragenSitaker: it defaults to an empty string, no?
07:30 < NickPresta> scandal: Ah, I see.
07:30 < LinuxMercedes_> xed: it is possible; I'm installing go to a
non-standard directory
07:30 < NickPresta> And I thought I read that all values were initializes to
their "zero" values (false, "", 0, etc)?
07:30 < xed> LM: Don't know. Maybe it never writes the stuff so shouldn't
even be a problem.
07:30 < scandal> NickPresta: yes
07:30 < KragenSitaker> scandal: oh, does it? awesome!
07:31 < LinuxMercedes_> xed: yeah, looks like it just stashes it in a
variable
07:31 < LinuxMercedes_> only problem would be /dev/urandom permissions wise

07:34 < scandal> NickPresta: one more issue. at line 49 do this:
shortURL=string(b); then just return;
07:34 < LinuxMercedes_> xed: what source file is the code you pastied from?

07:53 < NickPresta> scandal: I have. I am talking about features like,
reversing characters in a string from positions i to j. I'm not exactly sure how
to go about doing that given Go's immutable strings and such. Do I convert to a
byte array, make the modification and convert back?
07:53 < scandal> NickPresta: pretty much
07:53 < scandal> I'm sure the std library will get filled out in time.
ALthough I'm not sure what the process will be.

11:22 < jessta> diltsman: looked at bytes package?
11:22 < jA_cOp> anders_, the _obj dir should have an object file

11:24 < anders_> maybe theres something wrong with the file it is compiling,
but it should give me some kind of errormessage then?

11:28 < anders_> ok
11:29 < anders_> thats not necessary for now, i was just trying to compile
one single file with make. tired of writing 6g .. && 6l .. all the time:)
11:29 < jessta> diltsman: you could do that in a loop, tmpslice :=
myslice[i:i+3]
11:29 < anders_> but i need a main package, right?
11:29 < jA_cOp> if you want an executable, you need a main package with a
main function (main.main)
11:29 < diltsman> jessta: Yeah, I figured that out, but I was wondering if
there was a more Go-esque way of doing it.
11:30 < anders_> probably that's why it went wrong:)
11:30 < anders_> i only had one file. containting "package httpclient"
11:30 < jessta> diltsman: a slice is just a pointer and the length, so it's
cheap to make them
11:30 < jA_cOp> and capacity :V
11:31 < diltsman> jessta: Right, I read that in the documentation. I just
wanted to make sure I wasn't writing ugly code because I can't figure out how to
do it any way but the C way.

12:26 < __gilles> is another issue :)
12:26 < Snert> i figured that after i got it to compile and run some go
programs i could refine and correct
12:26 < __gilles> yup that's what i want to do
12:26 < __gilles> but after a first read
12:26 < __gilles> i realized that most of the file is unportable because it
relies on linux specific stuff
12:26 < Snert> i'm pretty much there, but my 8.out won't run
12:26 < Snert> :(
12:26 < __gilles> the /proc being one
12:27 < Snert> nah!
12:27 -!- m-takagi_ is now known as m-takagi
12:27 < Snert> /proc is a poor man's toilet
12:28 < __gilles> :)

12:28 < __gilles> i don't know if everything that the debugger needs can be
fetched from sysctl though

15:08 <+danderson> That is not quite exact. Go can do indexed access, which
the compiler can transform into pointer arithmetic for efficiency.

15:09 < blup> oui
15:09 < blup> i think i might have come off as rude :/
15:10 <+danderson> not at all, I'm just mildly disagreeing :)
15:10 <+danderson> well, I agree that there is no pointer arithmetic
available to the programmer
15:10 <+danderson> but you seem to imply that it leads to loss of
functionalit
15:10 <+danderson> +y
15:10 < blup> i was thinking embedded systems
15:10 < blup> but i believe that you can jsut use C there
15:11 * trost thinks erlang concurrency and go concurrency are actually fairly
similar
15:11 < blup> *go on using C there without it being much as a problem since
the hardware is gonna be way more of a problem than the programming language you
are using
15:11 <+danderson> very small embedded systems are a problem for a different
reason, because the runtime is quite large
15:11 < GeDaMo> If you're talking about accessing arbitrary address, you
could add a package to Go for that
15:11 <+danderson> compared to C's minimal "set up the stack pointer"
runtime
15:11 < trost> It's both about sending messages between
tasks/processes/whatevers
15:12 < blup> i think the go runtime is a very desiurable thing to have
15:12 <+danderson> trost: sure, but Erlang has a few different approaches on
the subject
15:12 < trost> fer sure
15:12 < jessta> for embedded systems you should probably just use C
15:12 <+danderson> by default Go channels use CSP semantics, where
goroutines have to rendezvous to transmit a value
15:12 * trost programs embedded systems with 4 GB RAM
15:13 * danderson programs embedded systems with 128 bytes of RAM :)

16:34 < Amaranth> XniX23: No, it doesn't have a behind the scenes cookie
store

request?

16:35 < Shihan> stupid question.. if your passing data into a c library,
what would be the difference between myfunctioncall("somedata") and

16:35 < Amaranth> Shihan: The second one is a somewhat slow way of making a
copy of the string
16:36 < XniX23> Amaranth: oh right, i forgot about that :)
16:36 < Shihan> for some reason, the first one works, the second does not...
its got me quite weirded out
16:36 < Amaranth> Shihan: I suppose the first one would also be a const
string
16:37 < XniX23> Shihan: try myfunctioncall(v:=fmt.Sprintf("somedata"))
16:37 < XniX23> omg what did i just write
16:38 < Amaranth> XniX23: I think that'll pass true to the function
16:38 < Shihan> yeah, i figured it might be going back to a const and thats
messing with it...
16:38 < Shihan> xni, yeah i tried that one already too
16:38 < XniX23> Amaranth: yes, dummie me
16:38 < Shihan> or at least, v:= fmt.Sprint...; myfunctioncall(v);
16:40 < XniX23> Shihan: i dont think you can do it that way, unless

tree just to strip out the use of fmt
16:41 < Shihan> i.e. v:= fmt.Sprintf("somestring: %s", mystring) would
rturn as a string what fmt.Printf("somestring: %s", mystring) would print to

17:22 < JBeshir> Python is a decent language. lack of type safety and clean
declarations makes kittens die, though.

20:25 < Amaranth> JPascal: You can make go programs that are in multiple
files
20:25 < jessta> exch: and you don't explictly implement an interface
20:26 < Amaranth> JPascal: You just compile them to *.8 files then call the
linker to link them all together into one binary
20:26 < Amaranth> JPascal: But you can't make a library using go
20:26 < KirkMcDonald> A dynamic library.
20:26 < jessta> exch: you implement an interface it the object happens to
have the methods required to implement the interface
20:26 < jessta> *if the object
20:26 < exch> hmm
20:27 < uriel> note: gccgo can do dynamic linking, and (if I got it right)

fields twice. Once for each struct (Rect and Circle)
20:42 < exch> for 2 fields thats hardly an issue, but for complex models
this can become tedious quite fast
20:43 < KirkMcDonald> annodomini: Spin off a goroutine for each channel

22:44 < facemelter> sladegen, jlouis, oh it seems as tho bison outputs to
cc.out instead of y.tab.h
22:44 < wimpog> is this correct: for number := start; number < start +
count; number++
22:44 < dga> Not sure. The challenge is that protobufs actually produce c++
code, and I'm not sure how well that would work. I think there's a third-party c
impl of protobuf that might do the trick, though, if needed.
22:44 < wimpog> for some reason it does not add start and count
22:45 < KirkMcDonald> Man, this library isn't even a thousand lines of code.
22:45 < KirkMcDonald> Though it probably will be by the time I'm done.
22:45 < facemelter> sladegen, jlouis, no sorry im mistaken.. it would have
to output both a .c and .h file, rite?

long computation, but for some reason it turns out that I don't need that value
any more, is there any way to just kill it off, without having to thread
throughout the entire computation a check on a channel which returns all the way
up to the top level if the computation has been cancelled.

23:43 < engla> annodomini: a goroutine started in a goroutine will not nest?
if it nests, and Goexit kills both, you have a solution, but it's unlikely
23:44 < yuanxin> annodomini: I've never looked at Erlang
23:44 < kuroneko> I like erlang. I just dislike the runtime.

of typed channels like Go, it has one message inbox per process, which is an

solved in Erlang
23:52 < ehird> The story is pretty simple I would think
23:52 < ehird> "Goroutines are distributed across machines".
23:52 * kuroneko cringes
23:52 < penguin42> ehird: I thought it defines them as being shared memory
23:52 < eno> i don't think it's that simple
23:52 < quag> ehird: depends if such a solution is needed
23:53 < dga> sure it does, eno - but you have to look behind the design. :)
"Deal with it at the application level, because that's how you do things in a
cluster environment."
23:53 < ehird> basically the same as GOMAXPROCS=cores*machines, and having
cores=all the cores of every machine
23:53 < ehird> of course it wouldn't be implemented like that
23:53 < ehird> but that's a simple, dumb, and possibly working strategy
23:53 < dga> (because in a cluster environment, there's no one-size-fits-all
when it comes to dealing with fault tolerance.)
23:53 < ehird> otherwise? The same as Plan 9 clusters.
23:53 < scandal> penguin42: after you call flag.Parse() your options will be
valid
23:53 < ehird> Same people, after all.
23:53 < quag> ehird: sockets + serialization :)
23:53 < ehird> ...and go is so plan 9 already.
23:53 < quag> ehird: what are plan 9 clusters like?
23:54 < penguin42> scandal: How does it actually achieve that - in the
statement var width = flag.Int() how does the assignment get deferred?
23:54 < ehird> quag: Hard to explain. Basically even single-machine
installations are multi-machine installations with only one member.
23:54 < ehird> quag: It relies heavily on 9P, the networked filesystem
protocol.
23:54 < ehird> (Since everything really is a file on Plan 9.)
23:54 < ehird> ((Evil offloading answer: Ask uriel!))
23:54 < kuroneko> hhahaha.
23:54 < kuroneko> or me.
23:55 < eno> can 9P be used on unreliable network?
23:55 < ehird> Or you, mysterious person.
23:55 < kuroneko> plan 9 is oriented around user-specific namespaces
23:55 < ehird> Distributed computing over an unreliable network? Awesome,
that sounds basically like, uh, a really fun thing.

23:55 < eno> why not
23:55 < scandal> penguin42: the flag package internally keeps pointers to
those options and fills them out when you call flag.Parse()
23:55 < dga> distributed computing over an unreliable network: sounds like
the real world. :)
23:56 < penguin42> ehird: If you're going to do bigscale distributed you
have to - after all on a BIG system something is bound to fail
23:56 < kuroneko> plan9 doesn't do much in the way of distribution though

23:56 < ehird> well, whatever
23:56 < ehird> cpu farm is close enough for me
23:56 < kuroneko> where you had a few expensive big machines, and lots of
cheap terminals
23:56 < mycroftiv> quag: plan 9 basic design is modular, a modern plan9
cluster schematically is a venti deduplicative data server backend, fossil file
server backed by the venti, and multiple CPU servers booted from the fossil, which
can all import each other's resources including synthetic filesystems
23:56 < scandal> penguin42: yes, see funcs like VisitAll and Lookup

you expect?
23:57 < kuroneko> well, yeah. :)
23:57 < ehird> in typical mycroftiv style you have to prod him for

23:57 < quag> so go is Plan 9's evil plan to take over the world, right?

23:57 < kuroneko> quag: or at least show the unix-users the error of their
ways :)
23:57 < mycroftiv> quag: there are definitely some connections in the
language to limbo, which is what the plan9 spinoff inferno is written in
23:58 < ehird> quag: ha, basically what i was saying!
23:58 < insane_coder> ehird: true, and ideally more Plan 9 ideas should be
brought to Linux, not just the proc filesystem
23:58 < ehird> linux /proc is crappy compared to plan 9's
23:58 < kuroneko> the main ideas from 9 I'd like to see is real, per-user
namespacing
23:58 < ehird> really crappy
23:58 < insane_coder> I'd like to see better file based hardware access like
Plan 9 had

--- Day changed Mon Nov 16 2009
00:00 < kuroneko> quag: sort of - each process inherits the namespace from
the parent
00:00 < quag> s/it/itself/
00:00 < kuroneko> but can add its own stuff which only it and it's children
will see
00:00 < kuroneko> so, on a 9 box, I can log in, and then mount some
filesystem which is private to me from somewhere else
00:00 < quag> would things like tcp sockets be handled as a file under a
specific location?
00:00 -!- petr_ is now known as petr
00:00 < dga> which gets amazingly awesome when you can easily lock your

00:00 < ehird> quag: yep! they are
00:00 < kuroneko> and only direct subchildren of my shell will see it
00:00 < ehird> /net

00:01 < dagle2> quag: each process has it's mount table.
00:01 < quag> does sound nifty
00:01 < quag> does Plan 9 have a path forward?
00:01 < kuroneko> it's open sourced.
00:02 < kuroneko> but it's not really going anywhere these days.
00:02 < dga> its creators are taking over google? :)
00:02 < dagle2> And you can see mount table for a process in /proc

00:57 < quag> what if there are more than 10 target arches? :)
00:58 < ehird> quag: do what plan9 does, use names
00:58 < wimpog> so really gccgo is having memory leaks, otherwise it's ok?

00:58 < quag> ehird: that is what utf8 is for :)
00:59 < ehird> wimpog: it leaks memory, it is worse at goroutines, it's much
(much! much!) slower, it lacks the nice plan 9 toolchain, and development is
focused on gc
00:59 < ehird> quag: :-D
00:59 < ehird> ég
00:59 < scyth> ehird, well, true parallelisation can come only with
threads/forks. Is it based on threads or?

00:59 < ehird> wimpog: the only advantage of gccgo is that the output
programs are a bit faster. I strongly recommend using gc + the plan 9 toolchain
(*l)
01:00 < engla> scyth: threads
01:00 < scyth> ehird, forks can't share a same memory space
01:00 < ehird> scyth: yeah, true
01:00 < ehird> i was just guessing without thinking
01:00 < engla> scyth: although goroutines are not 1 to 1 with threads
01:00 < wimpog> ehird: which gc and 9 toolchain?
01:00 < wimpog> ehird: I'm using 8g and 8l to compile
01:00 < ehird> wimpog: that's the [568]g and [568]l

01:00 < ehird> wimpog: then continue doing so

01:01 < ehird> Nope
01:01 -!- Manan [n=truthlim@142.46.164.30] has quit []
01:01 < ehird> You need gc
01:01 < ehird> cgo is gc-only
01:01 < ehird> (It uses gcc, though, but not gccgo)
01:02 < ehird> (In fact it uses both gcc and the Plan 9 C compiler (*c))
01:02 < Manish_mah> but the website says.. golang.org .. gccgo is the best
compiler u can use...6g..8gg can also be used but dont give u less efficient code
01:02 < ehird> Manish_mah: It's not the best.
01:02 < ehird> It just produces slightly faster code.
01:02 < penguin42> holy fuck - that worked!
01:03 < scyth> engla, so is is it just one thread per CPU core and then
async code withing each thread?
01:03 < ehird> But it compiles and links much much MUCH slower than gc,
doesn't let you interface to C, implements goroutines worse than gc, has no GC...
01:03 <+iant> ehird: wait, gccgo does let you interface to C
01:03 < sladegen> ehird: what does gc mean in the versus gccgo context?
01:03 < ehird> iant: hmm was cgo support added?
01:03 < ehird> sladegen: the (number)g/l tools
01:04 < ehird> sladegen: the name of (number)g collectively is gc, I guess
because it's the g commands, written in C
01:04 <+iant> ehird: it's simpler in gccgo, you can use an asm declaration
on a function declaration to give the C name of the function
01:04 < ehird> sladegen: (number)l is the linker you use with them; from
Plan 9
01:04 <+iant> see the bottom of http://golang.org/doc/gccgo_install.html
01:04 < ehird> the naming convention is from plan 9. gc is confusing though
01:04 < jlouis> this is perhaps a more idiomatic string reverse:
http://pastie.org/700404 -- I don't know if it is O(n^2) though :/
01:04 < ehird> since gc is the one with the GC :-D
01:04 < Manish_mah> see..i believe abt less efficient code...from 6g or 8g
...so if gccgo is avail y dun we use it ?
01:04 < ehird> iant: super-ugly!
01:04 < ehird> Manish_mah: [01:03] ehird: But it compiles and links much
much MUCH slower than gc, […], implements goroutines worse than gc, has no GC...
01:04 <+iant> it's not that much worse than the cgo dance in practice

03:57 < Amaranth> ah, http.ReadResponse blows up on "CONNECT
mail.google.com:443 HTTP/1.1" due to the lack of / and the :
03:58 < hstimer> I'm assuming that locals are just sitting on the stack
under normal conditions. But when you return the address of a local then it can't
be there. Was it marked by the compiler to be on the heap?
03:58 < Amaranth> It tries to say that is invalid and redirect to /443
03:58 < Ycros> hstimer: I'm pretty sure that's what happens, yes
03:58 < Ycros> hstimer: but we don't have normal stacks anyway
03:58 < hstimer> Or are they moved when the address is taken?
03:59 < hstimer> Same issue as lambda
03:59 < Amaranth> so then the browser says "CONNECT mail.google.com:443
HTTP/1.1" again since paths aren't used at all in this call and it just keep
repeating until the browser gives up due to excessive recursion
03:59 < Manan> hm guys, quick Linux nub question here, how do I log out of
sudo in a terminal?
03:59 < harryv> ctrl-d or exit(1) or whatevz.
03:59 < uriel> hstimer: if you return the address of a variable, IIRC the
compiler makes sure to allocate it in the heap
03:59 < Amaranth> so it's actually http.ParseURL that is failing

they are only slightly tuned at present; I guess we'll see over time
04:39 < engla> uriel: really? superficially they allow parting of work in

the golang.org one
04:40 < squirrelmetal> Innominate: good to know, thank you very much
04:40 < uriel> engla: again, I mentioned this in backlog: among other things
with tasklets you can't 'select' (nee alt) on multiple channels and more
importantly: if one tasklet blocks, they all block!
04:41 < engla> that I know. I can't find it in the backlog though
04:41 < uriel> engla: so stackless is basically doing *zero* concurrency,
and can't handle blocking io at all, while in go, if your goruoutine does
something that blocks, the other goruoutines will keep going just fine
04:42 < engla> without blocking IO goroutines are scheduled just like
tasklets
04:43 < uriel> engla: that is like saying MS-DOS and Unix schedule processes
the same as long as you have a single process

05:28 < ericmoritz\0> when would I want to use an array over a slice of that

05:28 < hansstimer> you need an array to start with

to pass slices into functions as arguments, but allocate arrays.

06:25 < dgnorton> Dreamer3_MBP17, for type assertion I think it's

07:36 < Dreamer3_MBP17> since the way to get the big disivor is divide by
the small divisors

09:08 -!- petr [i=uyawo@rzstud3.stud.uni-karlsruhe.de] has left #go-nuts []
09:08 < fabled> me___: mostly x86
09:09 < fabled> but i guess the same principals apply to all platforms
09:09 < sliceofpi> What's everybody's language backgrounds?
09:09 < KirkMcDonald> sliceofpi: I've spent the most time in C, C++, Python,
D.
09:09 < KirkMcDonald> sliceofpi: Dabbled in others.
09:09 < sliceofpi> KirkMcDonald: so you are a systems programmer, mostly?
09:10 < wobsite> C, Java mostly, but a bit of everything
09:10 < me___> okay. in linux/386, newosproc() (in
src/pkg/runtime/thread.c) creates host threads onto which coroutines are
multiplexed. these host threads don't go away atm.
09:10 < KirkMcDonald> I am actually paid to write Python. :-)
09:10 < me___> pkg/runtime/proc.c contains the go-level scheduler, which
takes coroutines and muxes them onto host threads (called Ms. yay single letters).
09:10 < wobsite> I mess around with a lot of languages, but most of what I
end up actually seriously writing stuff in is C/Java

development for my consulting company (Slice of Pi) but I also dabble in
customized PLM/CRM implementations using C#/VB.NET/Java/Javascript/whatever's
available.
09:11 < me___> there is a runqueue in proc.c, on which coroutines are
enqueued.
09:12 < me___> each M is inside scheduler(). we take one off, dispatch.
09:13 -!- cankoy [n=cankoy@94.54.13.77] has joined #go-nuts
09:13 < me___> any more particulars you were interested in?
09:13 < fabled> me___: proc.c looks the interesting bits. is scheduler run
on single thread, or multiple threads concurrently?
09:13 < me___> multiple afaik. each Mach (M) runs mstart at spinup.
09:14 < me___> a lock in the sched structure protects the coroutine queue.
09:14 < fabled> oh
09:15 < fabled> so it'll likely perform better when there's fewer goroutine
context switches
09:15 < fabled> since scheduling is not lock free
09:15 < fabled> how about the stack management?
09:15 < me___> i don't know, haven't looked into it..
09:16 < fabled> sounds like it just has custom epilogue and prologue code
for generated functions that alloc more stack from heap
09:16 < KirkMcDonald> I am given to understand that the current scheduler
(as well as the GC) are far from the final desired implementations.
09:16 < fabled> GC is to be rewritten according to web page
09:16 < me___> the GC is a mark/sweep that's marked 'NOT FOR PRODUCTION'.
09:16 < fabled> did not find anything about scheduler
09:17 < KirkMcDonald> I remember hearing something about the scheduler using
a single global lock for context switches or something. I forget.
09:17 < me___> re GC: i hear that they're looking into IBM's Recycler
project.
09:17 < KirkMcDonald> me___: Yes, I heard this, too.
09:17 < me___> KirkMcDonald: yes, that's case currently.

09:30 < UKRep547> the argument was you declare "var <names>
<type>", the argument being that in C "int* a,b" was confusing. Well of
course it's confusing. That's the wrong way of declaring variables in C. You
should put the asterisk next to the variable name, not the type name. Really, I
talk about comparing oranges to apples. Nothing confusing about "int a, *b, c;"
in C.

it will be available directly from your package too. Not sure though

it possible to have a go version of c extensions for python?
12:14 < mitsuhiko> my experience with go is that it's quite slow
12:14 < engla> what in gtk needs to be fast?
12:15 < mitsuhiko> gtk apps in python are as responsive as gtk apps in c, i
would not notice the difference
12:15 < jessta> the problem with gtk is callbacks

GTK+ bindings for Go; it'd be easier to knock together a generic

13:30 < dho> Snert: M is a `machine', G is a goroutine
13:30 < dho> remy__: string()
13:30 < dho> .String()
13:31 < remy__> damn, thanks
13:31 < dho> and something else i'm sure

13:32 < sladegen> conra|afk: do you have any connection with google or are

13:32 < Snert> dho: how does the goroutine relate to fn then?
13:32 < depood> oh, well .. thanks sladegen
13:32 < dho> Snert: fn is always mstart
13:33 < Snert> mstart?
13:33 < dho> defined in runtime/proc.c
13:33 < me___> mstart setups up the mach, then has it enter the scheduler.
13:33 < dho> Snert: Ms can have multiple Gs
13:34 < Snert> yes, I know
13:34 < dho> it's like thread pools or whatever.

13:35 -!- asmo [n=asmo@c-f6c5e055.1155-1-64736c11.cust.bredbandsbolaget.se] has
joined #go-nuts
13:35 < rog> hey dho
13:35 < me___> btw, that part makes me vaguely nervous. they aren't really
coroutines when its possible for them to be executing at once on more than one
Mach
13:35 < me___> rog: hi
13:35 < Snert> what I'm having trouble with is the invocation; how to factor
in G and fn; I'm implementing using rfork(RFTHREAD|RFMEM|RFNOWAIT)
13:35 <+danderson> conra|afk: yes? Why the ping?
13:35 < me___> Snert: after the rfork, you need to switch stacks in the
child to stk, then jmp to fn
13:35 < dho> Snert: the linux implementation is more accurate
13:36 < me___> look at the implementation of rfork_thread in the openbsd
libc_r (if that's what you use?)
13:36 < dho> me___: Gs don't jump Ms
13:36 < me___> dho: i'm working from memory, but there was only one runqueue
iirc?
13:36 < Snert> me__ doesn't rfork already assign a separate stack ?
13:37 < me___> iirc rfork just gives you more registers, it doesn't do the
stack stuff for you.
13:37 < dho> Snert: take a look at runtime/linux/$ARCH/sys.s
13:37 < dho> see the clone implementation
13:38 < dho> that's vaguely what you'll want to be using if you are rforking
13:38 < me___> dho: clone (and thr_create and lwp_create) take stacks.
clone and thr_create even take TLS params.
13:38 < dho> sure
13:39 < dho> but clone returns very differently from my thr_new
13:39 < dho> and works more like rfork in that regard in that it returns
twice
13:39 < me___> mm, yea.

13:39 < me___> whereas thr_create and lwp_create don't, fair.
13:40 < dho> right, they execute fn
13:40 < dho> but fn's always mstart, so i ignore it
13:40 < me___> i don't set fn to mstart, i have a wrapper to setup TLS
here...

13:40 * dho working on amd64
13:40 < dho> so i don't really have to deal with tls
13:41 < me___> how does that work on amd64?
13:41 < dho> also, youu don't set fn to mstart
13:41 < dho> but it is always mstart when newosproc is called
13:41 < dho> so
13:41 < me___> sure, 'fn'. my mind was constant propagating.
13:41 < me___> :)
13:42 < dho> 1 sec
13:42 < me___> on amd64, how does tls-equivalent work?
13:43 < dho> i believe you get it automagically
13:43 < dho> so you don't have to fake it or something; it's handled by the
kernel
13:44 < me___> okay; is GS still used?
13:44 < me___> or is segmentation dead on amd64?
13:44 < dho> you do have fsbase and gsbase in regs
13:44 < dho> but there's no user ldt
13:45 < dho> well, you can emulate it
13:45 < dho> and obviously amd64 has x86 compat

around rfork that does the fiddly stuff for you.
13:51 < Snert> i have been
13:52 < Snert> i see that, i found teh kernal code
13:52 < Snert> but doesn't appear to be exported in libc
13:52 < me___> doesn't matter for this exercise, since you're not linking
libc...
13:52 < dho> you're just reimplementing
13:52 < dho> don't try to do this portably -- it isn't

13:52 < dho> :)
13:53 < dho> the problem with the BSDs is that porting it is very

has joined #go-nuts
13:54 < dho> you can't, this is not portable by definition
13:54 < me___> Snert: good luck. i imagine you could construct this to be
portable between the BSDs, but even that'd be a stretch...
13:54 < dho> not unless we all use rfork, and i don't think that's a good
idea
13:54 < dho> i'd rather use the kernel threading interface
13:54 < me___> i don't either. these are nicer :)
13:55 < alexsuraci> oh good, gopaste is still up.
13:55 < me___> also #dragonflybsd notes that the lwp_create* here shares
signal properties that rfork doesnt
13:55 < dho> also syscall conventions are different
13:55 < Snert> the thing is that kernal threading in OBSD is based on rfork
13:55 < dho> that makes sense.
13:55 < Snert> along with a few other bits and bobs
13:56 < Snert> I found this yesterday
http://www.openbsd.org/papers/eurobsd2005/tedu-rthreads.pdf
13:57 < Snert> of course teh switch to kernel threads on OBSD hasn't been
completed yet; FreeBSD and NetBSD 5 have
13:57 < Snert> but for teh purposes of Go, I think the what's there is
enough
13:57 < dho> ok
13:57 < dho> have you looked at the linux clone implementation in Go yet?
13:57 < dho> I'm pretty sure that's very similar to what you're goign to
want to do
13:58 * Snert one day has to explore the internels
13:58 < dho> Snert: take a look at the syscalls section of the paper you
just linked
13:58 < dho> Snert: that's pretty much all the information you need.
13:59 < Snert> i know :) I've been studying it
13:59 < dho> then the MD code section describes rfork_thread.
13:59 < dho> you just need to re-implement that in assembler
13:59 < Snert> obsd has a copy of teh freebsd rfork_thread code
14:00 < Snert> just be nice if I could just link to it
14:00 < dho> you can probably use my thread.c semaphore locking
implementation
14:00 < dho> you can't just link to it
14:00 < me___> dho: thanks for the offer for amd64; i've some stuff i need
to get done in the next few days, but then i'll come back to dealing with this..
i'd like to finish i386 first though.
14:00 < dho> np
14:01 * dho needs to sync up with reppie and see how his freebsd/i386 work is
coming
14:01 < depood> is there any better dok than
http://golang.org/pkg/syscall/#tmp_502 ?
14:01 < me___> hmm, would it be worth having a wiki page or some other
synchronization tool for go-bsd work?
14:02 < dho> me___: i was considering writing a document on what i did
14:02 < dho> depood: what are you trying to do?
14:02 < dho> depood: that interface is very non-portable
14:03 < me___> okay, i think it'd be nice to have shared editable thingy, so
we'd be able to update port statues and what's shared and how each of the other
ones work?
14:03 < me___> *have a ...
14:03 < depood> understanding some of the basics in the go tutorials ^^
14:03 < me___> would be pretty cool if you wrote something up though.

14:18 < etianen> A pretty major thing I've noticed (although I may be
missing something) in the standard library, is that there seems to be a lot of
passing byte arrays around for strings. This looks to be a step backwards from
the language-level unicode handling of something like Python.

14:52 < etianen> iant: calling RuneCountInString whenever a string length is
needed
14:53 <+iant> If that is too many characters for you to type, write a helper
function
14:53 < sladegen> you mean typing it?
14:54 < etianen> It essentially means that any code that deals with strings
needs to import the utf8 library and then call a massive method name each time a
length is required. Seems to go against the 'terse' aim of the language.

UTF-8, UTF-8 is built into the language in very minimal ways; the main exception
is using range over a string; everything else is library code
14:57 < dho> flags and offset or something, I don't remember
14:57 < hstimer> etianen: in java (don't ask why I was writing a server
java; complete mistake) I got around this by keeping the characters as bytes and
not strings. a little bit of a pain, but I didn't pay the unicode overhead which
is larger in java than Go I believe

14:59 < etianen> I've grown pretty fond of the Python approach of dealing
with 'bytes' and 'str' objects completely separately. If you want to treat bytes
as a string, then decode them. If you want to treat a string as bytes, then
decode it. It means that at any point in your code, you know whether your data is
suitable for string manipulation.

19:10 < KirkMcDonald> XniX23: Your regex contains no groups.
19:11 < scyth> can someone explain to me, what are goroutines, if not
threads? I mean, I know they're threads but I'm not sure if this is just a
highlevel api on threads or there something else?
19:11 < nickjohnson> Do channels support multiple senders and/or receivers?
19:11 <+iant> scyth: they are coroutines multiplexed onto OS threads
19:11 <+iant> nickjohnson: yes
19:11 < Amaranth> nickjohnson: sure but once you read something from a
channel it's gone
19:11 <+iant> yes
19:11 < KirkMcDonald> XniX23: Do you want to retrieve all of the matches of
the regex within the string?
19:11 < XniX23> KirkMcDonald: even if i group that regex (a.b) then i get as
output "acb acb "
19:11 < XniX23> yes
19:11 < nickjohnson> Amaranth: fine with me
19:11 < Amaranth> Which is the reason I don't think I can actually do what
I'm trying to accomplish
19:11 < KirkMcDonald> XniX23: That would be the AllMatchesString method.
19:11 < XniX23> but if im not mistaken i should get also the "adb"
19:12 < XniX23> ohhh
19:12 <+iant> Amaranth: if you want many receivers for a channel, put in a
goroutine which reads one value and writes multiple values
19:12 < KirkMcDonald> XniX23: MatchStrings matches once, and then returns
the values of all of the groups in that match.
19:12 < Amaranth> iant: eh?
19:12 < XniX23> KirkMcDonald: thanks, dunno how i missed that func ˇ_ˇ
19:13 < Amaranth> iant: So if I have 2 things that want that message I
should make a goroutine that waits for that message then shoves two copies of it
back into the channel?
19:13 < hagna> how many goroutines are multiplexed onto one OS thread?
19:13 <+iant> well, I was thinking that it would shove the value onto
different channels
19:13 < Amaranth> I think I'm just doing this wrong
19:13 <+iant> Amaranth: in fact, it would have to use a different channel
19:13 < XniX23> works like a charm now

covered somewhat in the course slides
19:15 < Amaranth> iant: wait, select {} can work on more than channels?
19:15 < dho> hm
19:15 < uriel> Amaranth: what else would it work on? uh?
19:15 < dho> timeout_test.go will always fail with a kernel that supports
ipv6.
19:15 <+iant> Amaranth: no, just channels, but you should be able to use a
goroutine to turn any other input source into a channel
19:15 < Snert> dho: did you ever hit this: ./8.out: Cannot allocate memory
??
19:15 < dho> it seems
19:15 < dho> Snert: no
19:15 < KirkMcDonald> This fails to compile with the error: cannot assign to

19:16 <+iant> hagna: a single goroutine lives on a single OS thread at a
time, I'm not sure how anything else would be possible; a single goroutine can
move to different OS threads as need arises
19:16 < Amaranth> *facepalm*
19:16 < KirkMcDonald> I'm trying to see if this behavior is described in the
docs somewhere.
19:16 < Amaranth> I can spawn goroutines that do nothing but read and use
select to get data from them on the main thread and write it to the other
connection

19:17 < Amaranth> but wait, then the goroutines will keep running...
19:17 <+iant> Amaranth: sounds plausible, if your communication permits

19:17 < Amaranth> iant: Well I'm just shoving a struct down the channel so I
can add an error bool to it
19:17 <+iant> makes sense
19:18 < Amaranth> but how can I signal to the other goroutine that it needs
to stop...
19:18 < scyth> uriel, so new thread is created whenever comes a call to
start new goroutine, but there's already existing goroutine running (blocking or
not)

19:19 < KirkMcDonald> XniX23: It gives the complete match.
19:19 < uriel> (that usually means, when a goroutine is blocked on a syscall
for example)
19:19 < KirkMcDonald> iant: I will file an issue, although I don't even know

19:19 < XniX23> KirkMcDonald: so i can't get only groups with
AllMatchesString?
19:20 < KirkMcDonald> XniX23: Are you trying to get all of the groups in all
of the matches across the string?
19:20 < XniX23> KirkMcDonald: yes
19:20 < scyth> uriel, "only when needed" is what I'd like to know in more
details. I understand the obvious example is blocking syscall, but there are also
other scenarios
19:21 < KirkMcDonald> XniX23: You get to write a loop to do this.
19:21 < XniX23> KirkMcDonald: so there is no fast way like in python?
19:21 < KirkMcDonald> XniX23: Successively use MatchStrings, and also do: s
= [len(groups[0]):len(s)]
19:21 < KirkMcDonald> XniX23: It's about a three-line loop.

execution of nonblocking code, unless I put GOMAXPROCS(>2), which overrides
default. However, on blocking threads.. there's obviously no language limit on
number of threads

derived from an untyped constant becomes typed when it is used within a context
that requires a typed value."
20:24 < Baylink> Do they mean "is evaluated as typed"? Or does the constant
suddenly acquire a type, which it then carries around with it?

worry about who owns a reference to a string before mutating it. (Since you can't
mutate it at all.)
20:28 < KirkMcDonald> Or worry about someone else mutating a string which
you have a reference to.
20:28 < Baylink> Making it *possible* is useful. Making it *mandatory*
always seems to me to force people to figure out how to *actually* get their work

22:01 < pure_x01> rover: yes that would probably be possible but with this
it would be possible to easily add and remove filters by just adding them to the
list of filters.. but i see your point ..
22:02 < SRabbelier> iant: just not sure how to figure out what to do when

22:02 < scandal> penguin42: hrm, one problem is callbacks aren't supported.
is there way way to synchronously poll gtk+ events?
22:02 < jlouis> pure_x01: the ability to pre and post-process a channel is

Writing a goroutine that handles that for you does not look complicated to me, and
more customizable...
22:16 < pure_x01> korfuri: i guess you would have to connect a channel on
the remote computer on a specific port and when a connection occurrs both parties
can read and write to that channel.. so

do that way. What if the ports can't be fixed ? What if some process need to

somehow. Maybe setting up a callback... but that's more like a library's job

22:38 < SRabbelier> What does "import ( pathutil "path"; )" mean?
'pathutil' is not in the language spec
22:39 <+iant> SRabbelier: it means to import the package path, but to refer
to it as though it were named pathutil
22:39 < scandal> SRabbelier: it sets the namespace you use in your code for
accessing items in that package
22:39 < KirkMcDonald> It is roughly equivalent to "import path as pathutil"
in Python.
22:39 < SRabbelier> aaaah, I see, I thought 'pathutil' was special, it's
just the notation that is
22:39 < SRabbelier> thanks

project already?
22:44 < scandal> Not that I've seen.
22:44 < KirkMcDonald> I've just been working on my own project.
22:44 < delsvr> is there a reason why the shorthand initialization operator
(:=) can't be used at the top-level, outside of a func?
22:44 < XniX23> KirkMcDonald: care to share details? :)

http://www.cs.hmc.edu/~me/go/go-nuts-faq.html#short-decl
22:44 < KirkMcDonald> XniX23: A command-line option parser.
22:45 < pure_x01> When working with C++ for example isnt it more common to
put the objects on the heap and then pass around pointers (example via
smartpointers) .. Java as an example has no other option but to send around
pointers to objects.. So in Go wouldnt it be better to not have to write
*MyStrunct in each method declaration and let the default behavior for struct to
be pointers to structs.. since pass by value is not so comonly used when working
w
22:45 < pure_x01> ith structs.. ?
22:45 < delsvr> scandal: thanks
22:45 < rovar> KirkMcDonald: way to go work on something useful.. I've been

22:46 < rovar> pure_x01: D kind of does this. Classes are always passed by
reference, and structs are passed by value.. it was moderately annoying, imo
22:47 < SRabbelier> iant: any way to turn "my/file" into an absolute path
(other than prepending os.Getwd)?
22:47 < pure_x01> rovar: but isnt that the most common usage scenario with
classes.. to pass pointers around?
22:47 < KragenSitaker> pure_x01: not in general. consider structs such as
complex, interval, vector3, that kind of thing
22:47 < SRabbelier> since exec.Run seems to work only if you give it an
absolute file
22:47 < rovar> pure_x01: yes.. my goal is to make the data streams be
analogous to channels.. there might be some issues in practice though.. because
a data stream in OpenCL implies much more..
22:48 < KirkMcDonald> D's reference semantics are actually very similar to
Go's.
22:48 <+iant> SRabbelier: not that I know of
22:48 < rovar> specifcally.. an opencl kernel must process all data that is
sent to it.. it can't decide to stop early.
22:48 * SRabbelier adds to TODO list
22:48 < pure_x01> rovar: cool .. looking forward to it.. OpenCl is one of
my favourite topics to look in to more
22:49 < uriel> scandal: posted gotags to http://reddit.com/r/golang/
22:49 < rovar> KirkMcDonald: I really wish they'd have used D's invariant
arrays instead of their by-value arrays
22:49 < KirkMcDonald> rovar: I haven't really used D2.
22:49 * uriel doubts rovar has used Go much either...
22:49 < KirkMcDonald> rovar: But I much prefer Go's array types to D's
weird-ass static arrays.

23:25 < uriel> KragenSitaker: they are still hideous, and many of the api
details are not portable
23:25 < nmichaels> KragenSitaker: Yeah, I think all those operating systems
use the same tcp stack code.
23:25 < uriel> KragenSitaker: there are even portability issues between
differnt *nix systems
23:25 < KragenSitaker> nbaum: well, there's some code that has to be written
to bridge the gap between platform-specific APIs and the portable API you actually
want to use. do you want that code to be written in Go or in C?
23:25 < uriel> nmichaels: no they don't
23:25 < KragenSitaker> nmichaels: no, they have widely divergent TCP stack
code
23:25 < KragenSitaker> uriel: yes, I know
23:25 < nbaum> Go, I would say.
23:26 < nmichaels> uriel: What's etc/hosts doing on windows machines then?
23:26 < KragenSitaker> nbaum: that preference leads to my suggested solution
23:26 < blasdelf> there was once a time when they were all forks of BSD's
code
23:26 < uriel> nmichaels: who cares? the code is all different, and the
semantics of many things are different too
23:26 < vsmatck> One big annoyance of mine with portability of sockets is
how to do half-open sockets. Or async connections. With goroutines that doesn't
matter because you can just block while you connect.
23:26 < uriel> nmichaels: linux and bsd also have totally unrelated ip
stacks
23:26 < nbaum> nmichaels: etc/hosts isn't a TCP/IP stack thing.
23:26 < halfdan> is there anyone working on an plugin for netbeans?

23:29 < vsmatck> Like the macros for address family? It shouldn't matter
what those are because they're macros?
23:29 < nbaum> I don't know that that's true. I know that on Linux,
gethostbyname() happens in the C library, not the kernel, where the TCP/IP stack
happens. Specifically, it happens in the "name service switch". One can
configure whether to use /etc/hosts by editing /etc/nsswitch.conf.
23:30 < nbaum> OTOH, Windows might well access its hosts file from the
kernel, and maybe other Unices.
23:30 < vsmatck> gethostbyname() is legacy now that we have getaddrinfo
isn't it?
23:30 < uriel> iant: I know you are probably not in charge of those things,
but I was thinking that some kind of roadmap similar to what the Unladen Swallow's

expectations about what go can do now and what it is expected to be able to do...

23:59 < jimi_hendrix> \o/
23:59 < blasdelf> and because it never uses spaces or internal alignments,
your tabstop is not much of an issue

(4-space indent with 8-space tabs so the code looks right in Notepad et al)

00:00 < WalterMundt> I will, just haven't gotten around to it
00:00 < nbaum> WalterMundt: Perhaps you could configure your editor to
replace tabs with spaces upon loading a go file, and then run gofmt on it upon
saving. ;-)
00:00 < jimi_hendrix> YEAY FOR BRACES LANGUAGES
00:00 < hnsr> ts=8? infidel!
00:00 < fgb> every other language generally make people to write really,
really long times
00:00 < Ycros> iant: have you used 6cov?
00:00 < nbaum> Probably some surprises in store, of course.
00:00 < fgb> s/times/lines/
00:00 < hnsr> 4 is superior clearly
00:00 <+iant> Ycros: No, I haven't
00:00 < nmichaels> The only difference tabstops make is where you wrap your
lines.
00:00 < bthomson> ts=2!
00:00 < WalterMundt> hnsr: *shrugs* I really like my code to look the way I
write it when I load it in some arbitrary text editor. ts != 8 breaks that
00:01 < Ycros> iant: mm, okay, nobody in here seems to have tried it. I'll
write a post because it's not working correctly for me.
00:01 < jlouis> jimi_hendrix: it is easy to write compilers for any language
in the LALR(1) class. I expect Go is
00:01 < WalterMundt> or in less etc
00:01 < fgb> ReallyLongType longVariableName =
MyReallyLongClass->reallyExplicitFunctionName()->result()
00:01 < nbaum> WalterMundt: Indeed. That's why tabs are, in fact, evil.
00:02 < ehird> nbaum: no, srsly
00:02 < WalterMundt> if I remember to I configure my editor to expand them
by default, but again, the Go convention goes against that

00:02 < ehird> tabs are more semantic and give the reader more power with
less funging, plus 8-space default is good for reducing nesting
00:02 < nbaum> I do wonder why gofmt uses tabs instead of 4 spaces.
00:02 < jimi_hendrix> is there an option to have gofmt replace all the
current file with the correct one?
00:02 < WalterMundt> ehird: that only works when tabs are used consistently
throughout
00:02 < ehird> dude, ken thompson, rob pike — c, unix, plan 9 people. these
guys have never indented with spaces in their life
00:02 < nbaum> Google seem to use 4 spaces everywhere, though.
00:02 < nmichaels> fgb: I once worked in a shop that mandated
LongPackageName_hungrydribbleLongVariableNameSoAsToBeSufficientlyDescriptive.
Static as a storage class was not allowed.
00:02 < ehird> WalterMundt: no duh?
00:02 < blasdelf> WalterMundt: so what? since it never uses spaces, just
set your fucking tabstop
00:02 < ehird> WalterMundt: So do that.
00:03 < nmichaels> jimi_hendrix: yes...-f? I forget what it is.
00:03 < fgb> ok, basically in the text editors I use <tab> == \t
00:03 < WalterMundt> the number of files with semantic tabs I've run into is
maybe 1/100 of the number I've seen with mixed tab/space indents or no tabs at all
00:03 < nbaum> In fact, I assume the 4-space tab is godoc's choice?
00:03 < ehird> WalterMundt: blame emacs
00:03 < blasdelf> WalterMundt: which is why gofmt exists!
00:03 < ehird> nbaum: no, your browser's
00:03 < fgb> it displays as 4 ' ' in text editor
00:03 < nbaum> I see from godoc that it is.

ever.

00:05 <+danderson> (I think this has already happened a couple of times)
00:05 < nmichaels> WalterMundt: So you have seen some files with 100% tabs?
00:05 < nbaum> Hey, it only requires my changing my copy. :p
00:06 < ehird> nbaum: go's repository mandates calling gofmt beforehand
00:06 < ehird> pretty sure that's as close as damn it you can get to having
an opinion
00:06 < ehird> also, effective go tells you to use gofmt's conventions
00:06 < nmichaels> It's easy to change my copy of gofmt then run the real
gofmt before submitting code to anyone else's eyes.
00:06 * nbaum nods.
00:07 < nbaum> That's what I'd be inclined to do. Then nobody needs to get
hurt.
00:07 < WalterMundt> nmichaels: I have, once in a while. It's actually
tolerable, though it requires reconfiguring my editor because my default config is
set up for braindead-mixed-tabs mode that is the status of most files I open from
random sources
00:07 < fgb> nmichaels, I guess that's the whole point on having a gofmt
after all...
00:07 < kuroneko> Ycros: 6cov is demonstrating similar brokeness
00:07 < fgb> so noone bitches about conventions
00:07 < nmichaels> Heck, I could have emacs run fake-gofmt before opening
files and gofmt right before saving them.
00:07 < Ycros> kuroneko: aha! someone else who's tried it

00:07 < SecretofMana> Some guy linked it to not having usr/bin/time
00:07 < SecretofMana> but apparently I do have it
00:08 < SecretofMana> I mean when installing Go, sorry
00:08 < ehird> i think the thing is that gofmt is tailored according to the
structure of go
00:08 < nmichaels> fgb: yeah, it seems sane enough to me
00:08 < ehird> so going against it will make it harder for you to write go
that "flows" naturally
00:08 < nbaum> The Emacs-mode indentation is All Wrong...
00:09 < SecretofMana> It installs for like five minutes, then a bunch of
those errors occur, then eventually I get:
00:09 < SecretofMana> > panic PC=xxx
00:09 < SecretofMana> 0 known bugs; 0 unexpected bugs; test output differs
00:09 < ehird> and indeed, the existence of gofmt and the fact that the
makefiles included make all the decisions for you is very indicative that this is
to avoid holy wars and to have One Standard To Rule Them All
00:09 < blasdelf> Go is the only extant language where all the code is
\t-only
00:09 < ehird> SecretofMana: on os x? had the same problem when upgrading
to latest -r release
00:09 < ehird> blasdelf: some c code.
00:09 < nmichaels> ehird: Not that anyone has to care what I see, but it's
very hard for me to read code when curly braces don't line up. Instead of being
lazy, I just fix it while I'm looking at code and un-fix (or fix, depending on
your perspective) it when I'm done looking.
00:09 < bogen> ehird: yeah, I just gave up on fighting with gofmt (it won):
gofmt -w -tabwidth=2 -spaces=true -comments=true
00:09 < blasdelf> don't ruin this exciting possibility for the rest of us

to go and how expensive is it if you need to create a huge of these channels?

didn't get it. Why is this language interesting? What is it trying to fix that
other languages do incorrectly?
02:15 < JordiGH> What is it meant to be used for?
02:15 < KirkMcDonald> Either way, you need to unbox the values when you pull
them out.
02:15 < KirkMcDonald> JordiGH: interface{} is sort of like a void* in C, or
perhaps an Object reference in Java.
02:15 < Jerub> JordiGH: easy concurrency, nonsuck string handling, reasonble
built in types.
02:15 < sladegen> world domination!
02:15 < uriel> alphazero: you need a goroutine to notify when the timeout
happens, and then the gorroutine that receives the timeout needs a way to listen
on whatever channel you want, plus be able to get the timeout notification
02:15 < JordiGH> Jerub: Built-in thread handling? Hm.
02:16 < KirkMcDonald> (Except an interface{} can refer to any type.)
02:16 < JordiGH> Does it have reflection?
02:16 < Ycros> jimi_hendrix: please don't use ints to store pointers
02:16 < Jerub> JordiGH: no, i said concurrency. it's more complicated than
thread handling.

02:17 < KirkMcDonald> jimi_hendrix: To get the int back out: i.(int)

02:55 <+agl> jgoebel: combining chars -> consider q̂, it's two code
points: q and ^. If you reverse the code points you get ^q which is quite
different because ^ will combine with the previous character.

03:51 < scandal> currently, yes
03:51 < jgoebel> is there any good reason i can't branch?
03:51 < scandal> there was a reason on the contributor page
03:51 < uriel> hg clone is fast

03:53 < scandal> The Go repository is maintained as a single line of
reviewed changes; we prefer to avoid the complexity of Mercurial's arbitrary
change graph.
03:54 < jgoebel> not sure what that means
03:55 < jgoebel> i only meant local branches for my convenience
03:55 < jgoebel> or can hg not do that?
03:55 < jgoebel> i do that in git all the time
03:55 < scandal> i don't believe so. if you create a branch, and then push
it goes along for the ride
03:55 < jgoebel> well i'm not a commiter
03:55 < jgoebel> i can't push anyways
03:56 -!- Garibaldi [n=adalton@173-16-117-14.client.mchsi.com] has quit

03:56 < scandal> well, if you want, make a clone without the code review
extension and you can branch in there
03:56 -!- marciofss [n=marciofs@189.105.58.191] has joined #go-nuts
03:57 < jgoebel> or i can hack code review :)
03:57 < scandal> i think they would be happy to include a patch that allowed
local branches without messing up the main line
03:58 < jgoebel> again, if you aren't a commiter you can't mess up the main
line... or maybe i don't understand hg at all
03:58 < scandal> you dont need the code review extension enabled then
03:58 < jgoebel> hmmm
03:58 < jgoebel> that is how non-commiters contribute, is it not?
03:59 <+agl> jgoebel: hg doesn't do multiple branches in the same working
directory
03:59 < jgoebel> agl: it doesn't?
03:59 <+agl> jgoebel: it does have a concept of multiple heads in the same
branch, but they're not the same.
03:59 < jgoebel> i was almost positive it did

04:02 < jgoebel> what would be so difficult about it?
04:02 < jgoebel> just run them side by side
04:02 < kuroneko> agl: probably easier to start a revolt in G and switch
everybody over to git >_>
04:02 < kuroneko> *cough*
04:02 < jgoebel> just have to double commit
04:03 < kuroneko> "ew"
04:03 < jgoebel> but i you were working on a patch per branch you could make
tons of git commits then squash those into one changeset for hg
04:03 < Jerub> http://mercurial.selenic.com/wiki/ShelveExtension
04:03 < Ycros> at least I'm happy to work with and learn new version control

04:12 <+agl> kuroneko: hg-git is for git upstreams sadly.

04:12 < kuroneko> make your local git tree an "upstream"
