00:36 < str1ngs> output of my build system after building gcc
00:36 < skelterjohn> it took longer to build go than gcc?
00:37 < str1ngs> 33 minutes to build gcc barebones
00:37 < str1ngs> go takes 40s
00:37 < skelterjohn> oh minutes
00:37 < skelterjohn> one thing to remember
00:37 < skelterjohn> is that go can compile only one language
00:37 < str1ngs> this is a barebones gcc not libs even :P
00:37 < skelterjohn> gc, i mean
00:38 < skelterjohn> gcc does a lot of stuff
00:38 < str1ngs> I'm not knocking gcc just a pain to build
00:39 < str1ngs> anyways when I"m done I'll be able to produce a system
agnostic go toolchain including gccgo ..  hopefully
00:39 < str1ngs> gccgo might not be that easy
00:40 < str1ngs> what that means is you can download a binary packaget with
gcc gccgo with make etc.  and get going

02:15 < Emmental> Go is cool.  I started learning it a couple of days ago,
and I have a small program working already.
02:16 < steven> oh?  nice.
02:16 < steven> Emmental: sweet, whats it do?
02:16 < Emmental> Fetches some data over http, does some analysis.  I have a
few questions.
02:18 < steven> cool
02:18 < steven> shoot
02:19 < Emmental> out of 4 different sqlite bindings, what do I miss out on
if I just go with Russ Cox's one?
02:19 < steven> i just went with russ's when i made gorm
02:19 < steven> which you may find useful, but probably not yet
02:19 < steven> its in development

02:22 < Emmental> sweet, gorm is basically what I needed

02:45 < skelterjohn> steven: my paper deadline has passed - i'd like to hear
a bit about what you plan for your framework
02:46 < steven> skelterjohn: perhaps it should be a mailing list thing
instead?
02:46 < skelterjohn> that's up to you
02:46 < steven> although im afraid of sounding stupid by posting on there,
perhaps someone already thought of this and ill get a big fat "if you would have
searched the ML you would have seen this has already been done you idiot" in
response
02:47 < skelterjohn> some MLs are like that
02:47 < skelterjohn> i haven't noticed gonuts to be like that
02:47 <@adg> have you searched the mailing list?
02:47 <@adg> if you have, and haven't found anything, then nobody can say
that ;)
02:48 < steven> adg: im not sure what to search for honestly
02:48 < steven> on a related note: i suck at figuring out a good google
search phrase when im stuck on whatever
02:48 <@adg> orm, template, rails, framework
02:48 <@adg> that kind of thing
02:49 < steven> hmm yeah

02:50 < skelterjohn> is there a way to switch the branch of one directory in

old branch perhaps?  I don't really know anything about hg
03:03 < skelterjohn> i switched to release, rebuilt http, and switched back
to tip
03:03 < skelterjohn> because not being tip broke other stuff
03:04 < skelterjohn> i should probably stick to weekly or something

06:29 < pingveno> I'm looking at writing something to create the beginnings
of an Arch Linux package based on goinstall.  What is the best way to deal with
installing into the package build directory?
06:30 < pingveno> The package build directory being the place where files go
that will later be tarred together.
06:31 < KirkMcDonald> pingveno: It might be simplest just to put it under
opt or something.
06:32 < KirkMcDonald> But I know nothing about Arch's package manager.
06:33 < pingveno> An example on how it's done:
http://aur.archlinux.org/packages/python2-blist/PKGBUILD
06:34 < pingveno> build() {...} is the important part.
06:35 < pingveno> So with Python's setuptools system, the Arch system tells
it to install into $pkgdir
06:35 < pingveno> it = "python2 setup.py install"
06:39 < KirkMcDonald> The trouble is that, as far as I can tell, Go doesn't
play that nicely with being installed under a prefix.
06:39 < KirkMcDonald> Though you can arrange things so that it works.
06:39 < KirkMcDonald> But you have to wrangle the environment variables
somehow.
06:40 < pingveno> Oh, the joys of environmental variables...
06:40 < pingveno> I'll do some more work on it...  later...

07:39 < pingveno> ah
07:39 < str1ngs> each distro can do what they want.  but most try to keep to
FHS where they can
07:40 < pingveno> I want to keep as close to what other people do as
possible.

11:32 < jnwhiteh> alternatively, use gofix =)
11:32 < jnwhiteh> if its a recent change
11:35 < xyproto> jnwhiteh: Now I understand my confusion.  The latest
changes in the link you give me, does not correspond to the source that appears in

11:35 < jnwhiteh> well what release are you using

11:36 < jnwhiteh> as in tip, or latest release?
11:36 < jnwhiteh> well it matters, as golang.org only shows the latest

11:47 < jnwhiteh> http://gonuts.org/ has the documentation on tip
11:47 < jnwhiteh> or you can use godoc to spawn your own http server/view
the docs
11:47 < jnwhiteh> then you have the docs for teh version you're using =)
11:48 < xyproto> nice, thanks :)

13:05 < xyproto> I'm trying to follow the tutorial at
http://cheesesun.blogspot.com/2009/12/basic-cgo.html, in order to learn how to
call C-functions from Go. After finding a workaround for why the Makefile didn't
work, I've stranded at this error: _obj/_cgo_gotypes.go:59: invalid recursive type
_Ctypedef_WINDOW
13:06 < xyproto> What could it be?

depends on itself

14:03 < steven> how do you disable certain packages like goplay does?
14:04 < xyproto> skelterjohn: true.  The float64 value of the same

find a math.Round() function either.  How can I make it go from 0.9999...  to 1?

14:05 < exch> Presumably something really obvious is going on here, but I'm
not sure I get it.  http://pastie.org/1695964
14:05 < exch> the a < b check on line 24 fails when both are 0.1
14:06 < exch> I would guess that, since amount is the result of a
calculation, it isn't exactly 0.1.  Strangely, it works properly when you input
'0.17' to the routine instead of '0.16'
14:07 < steven> i cant find anything on the mailing list about how to
disable system calls when compiling go
14:07 < steven> snap.
14:08 < skelterjohn> it is impossible for a floating point to be exactly 0.1
14:09 < exch> mm
14:09 < skelterjohn> it needs to be some combination of powers of 2
14:09 < skelterjohn> otherwise you don't have it exactly
14:09 < exch> So it's just a fluke then that 0.17 as input works
14:09 < skelterjohn> yes
14:09 < exch> righty
14:10 < skelterjohn> well, i haven't examined your source
14:11 < skelterjohn> for that app i'd suggest counting in cents rather than

was only added a release or two ago.
15:00 < monokrome> The library that I am trying to build seems to not tell
me all of it's dependancies :)
15:00 < monokrome> oh okay
15:01 < monokrome> How can I see what version I have?
15:02 < exch> monokrome: go into $GOROOT and type hg indentify
15:02 < xyproto> monokrome: 6g -v may also be helpful
15:02 < exch> or that
15:02 < monokrome> $GOROOT isn't a mercurial repository

15:03 < monokrome> I just used the go package
15:04 < monokrome> http://paste.pocoo.org/show/357159/

15:07 < monokrome> xyproto: I guess that I need to learn how to set up AUR
first :)
15:07 < xyproto> monokrome: of course, it's not so fancy as yaourt, where
loads of packages can be installed without confirmation with a single command.
But, it's more scary.
15:07 < xyproto> (yaourt)
15:08 < xyproto> (Since all AUR packages are user-submitted).
15:08 < xyproto> monokrome: you don't need to set it up, you just need an
AUR helper.  It's also possible to download a PKGBUILD text file manually, and
just run "makepkg" in the same directory.
15:09 < xyproto> It's just a fancy framework for text-files, really.
15:09 < monokrome> xyproto: Yeah, figured it out.  I guess it just generates
pacman packages?
15:09 < xyproto> yes
15:09 < monokrome> Cool :)
15:09 < xyproto> yeah :)
15:09 * monokrome has been building/installing everything manually :O
15:10 < xyproto> If you install go-hg, mind that you probably have to run
/etc/profile.d/go.sh manually (or log out and in again)
15:10 < xyproto> to get GOROOT and friends
15:10 < monokrome> yeah
15:10 < monokrome> and I have to set GOARCH
15:10 < monokrome> because I don't think it's there by default :(
15:11 < xyproto> yes.  I commented on the go-hg package today, asking the
author to add GOARCH.
15:12 < xyproto> I see now that he's answered too.  He doesn't think it's
needed anymore, as "OROOT is the only thing
15:12 < xyproto> that needs to be set to build packages with default
15:12 < xyproto> makefiles."
15:12 < xyproto> *GOROOT
15:12 < monokrome> :(
15:12 < xyproto> So, if he's right, GOARCH isn't needed anymore (?)
15:13 < monokrome> Well, this library was pretty mad without it!  :)
15:13 < monokrome> ack
15:13 < monokrome> It didn't set up GOBIN either?
15:13 < steven> where do you guys put $GOROOT ?
15:13 < steven> i have it = $HOME/.go
15:14 < xyproto> steven: /opt/go here

though :P
15:51 < xyproto> str1ngs: you still have to do the work of actually
verifying everything, for both yaourt and cower, to be safe.  And with yaourt, you
are asked to edit each and every PKGBUILD unless you provide --noconfirm
15:52 < xyproto> str1ngs: yeah, haskell packages, that's another thing.  I
truly wish there was a system-wide database that had a list of all functions for
all libraries installed, including a checksum of the sourcecode for each and every
function.  That way, applications could depend on function signatures + checsums
instead of the fallible library version numbers.
15:52 < str1ngs> xyproto: yes but..  with cower I get to keep all the
PKGBUILD in a place of my choosing
15:53 < str1ngs> xyproto: with linux best you can do is /usr/include.  the
dependancy hell is not going away antime soon.  one of the appeals for Go
15:54 < xyproto> str1ngs: you can choose a directory for yaourt to store
PKGBUILDs as well, though
15:54 < xyproto> str1ngs: also, I think one can do better than /usr/include.
I'm a slight optimist.  :)

package.  use something like go-hg as dependancy.  but because its in /opt.  for
cmd packages it would still have dependancy on go-hg even though in reality its
only a make depend.
17:06 < str1ngs> pingveno: then you need figure out how to pass DESTDIR as
$pkgdir DESTDIR is not a goterm.  I would imagine it can handle something like

17:32 < steven> Jesus!
17:33 < skelterjohn> ok
17:34 < steven> do you happen to know of a way to compile Go to disallow
system-level operations?
17:34 < steven> im trying to reproduce http://golang.org/doc/playground.html
in a safe manner.
17:35 < skelterjohn> you can't - you can just remove all syscalls from
libraries
17:35 < skelterjohn> but people can still bring in their own .s files
17:35 < skelterjohn> and call them anywya
17:35 < skelterjohn> that being said, i don't know exactly what they did for
the playground
17:37 < xyproto> is using gofmt with any particular settings the "blessed"
way of formatting source code?
17:38 < skelterjohn> the setting i use is -F

17:42 < steven> theres a textmate keyboard shortcut to do it in your open

17:42 < skelterjohn> well, what i actually use is gb -F
17:42 < skelterjohn> but that's another issue
17:43 < xyproto> What are the requirements for a go-application to be
ultimately "blessed"?  Source code formatted with gofmt, tests in *_test files,
Makefiles that include the Go makefiles, godoc?  what else?
17:43 < skelterjohn> depends on what you mean by "blessed"
17:43 < skelterjohn> blessed by whom?  for what?
17:44 < xyproto> By the Go-crowd.  For showoff-purposes.  :P
17:44 < skelterjohn> then don't worry about it, because no one cares :)
17:44 < skelterjohn> but if you want to get something into the core,
standards are higher
17:44 < xyproto> Okay, okay.  By the strictest, most fanatic Go-programmer

possible.
17:45 < xyproto> *the purpose of the utility
17:46 < xyproto> I wanted to learn the full-cycle process, from coding to a
little Arch package, before creating anything larger
17:46 < xyproto> addinclude.roboticoverlords.org
17:46 < xyproto> I realised today that I should use gofmt, the fancy *_tests
and perhaps also godoc.
17:47 < skelterjohn> godoc is just commenting your code well
17:47 < skelterjohn> gofmt should be run, yes
17:47 < skelterjohn> and if it makes sense, tests are good
17:48 < xyproto> yes, I agree

18:05 < eaburns> hello
18:06 < eaburns> I am curious about the append() function for slices.  If I
append 1 element at-a-time, when it comes time to grow the array that is backing
the slice will the capacity grow by only 1 or will it grow by doubling?
18:06 -!- artefon [~thiago@dhcp19.usuarios.dcc.ufmg.br] has quit [Quit: bye]
18:08 < skelterjohn> doubling
18:09 < hypertux> eaburns, the only thing the language spec says is that it
will allocate a "sufficiently large slice"
18:09 < hypertux> but in practice, it's usually doubling
18:09 < eaburns> thanks
18:10 < skelterjohn> and if you examine the implementation, go does this by
doubling
18:11 < eaburns> I guess that I am trying to decide when to use a slice and
when I should use containers/vector.  Is the advantage of the vector just that it
provides a slightly higher-level set of functions?
18:11 -!- sauerbraten [~sauerbrat@p508CD7AD.dip.t-dialin.net] has quit [Quit:

18:11 < skelterjohn> you should just use slice
18:11 < pharris> eaburns: containers/vector mostly dates back to the dark
ages when we didn't have append() yet.
18:11 < skelterjohn> containers/vector was an experiment that never really
caught on

18:19 < skelterjohn> the vector stuff works perfectly well
18:19 < skelterjohn> it just has dubious value
18:20 < eaburns> sure but I guess that I would like to avoid packages with
dubious value.  Especially if there is an alternative convension like
slices/append()
