08:08 < araujo> can I dynamically allocate space for an array?
08:08 < araujo> something like: var d [len(t)]int ?
08:09 < rsaarelm> Yeah, use make.
08:11 < araujo> ooh right, thanks rsaarelm
08:16 -!- dacc [~dan@c-67-171-32-251.hsd1.wa.comcast.net] has joined #go-nuts
08:18 < dacc> how does casting work in go?
08:18 < dacc> can't seem to find any docs
08:18 < KirkMcDonald> dacc: Go doesn't have casts as such.
08:18 < KirkMcDonald> It has type conversions.
08:19 < dacc> e.g.  i have a byte i read from a binary file that's a uint8
08:19 < dacc> ah ok
08:19 < KirkMcDonald> dacc: And what do you want to do with it?
08:19 < araujo> type T struct {}; t := new(T); v, ok := t.(*T) // is this a
valid type assertion?
08:19 < dacc> KirkMcDonald: i'm writing a parser for a binary file format
08:20 < KirkMcDonald> araujo: You're asserting that something is already its
static type?
08:20 < dacc> KirkMcDonald: so i'd just like to get the byte value
interpreted as a uint8
08:20 < KirkMcDonald> araujo: And, I think the answer is no.  't' would have
to be of an interface type.
08:20 < araujo> KirkMcDonald, that only makes sense to do with for example..
interfaces right?
08:20 < araujo> aha
08:20 < KirkMcDonald> dacc: byte and uint8 are actually the same type.
08:21 < KirkMcDonald> dacc: But if they weren't, it would look like: byte(x)
08:22 < KirkMcDonald> dacc: Er, uint8(x).  Whatever.
08:22 < dacc> KirkMcDonald: ah ok, cool
08:22 < araujo> type T struct{}; type Any interface{}; t := new(T); v, ok :=
t.(Any)
08:22 < araujo> what about that one?
08:22 < KirkMcDonald> dacc: http://golang.org/doc/go_spec.html#Conversions
08:22 < dacc> feels like python =)
08:22 < dacc> KirkMcDonald: thanks much
08:22 < KirkMcDonald> dacc: It is, in fact, very much like Python, given
that Python doesn't have type casting, either, but conversions.
08:23 < KirkMcDonald> araujo: Also no, since t is still not of an interface
type.
08:24 < KirkMcDonald> var t Any = new(T); v, ok := t.(*T)
08:27 < araujo> KirkMcDonald, even though the Any is the empty interface?
08:27 < KirkMcDonald> Why would that make a difference?
08:28 < araujo> well, because t implements the empty interface too?, so the
type assertion is true?
08:29 < KirkMcDonald> Type assertions on non-interface types are known to
fail or not at compile-time.
08:29 < KirkMcDonald> They are pointless.
08:29 < KirkMcDonald> And they are disallowed.
08:30 < araujo> mm I see
08:31 < KirkMcDonald> If you merely want to get an Any which refers to t,
you can just say: Any(t)
08:31 < araujo> I see now, thanks :)

15:21 < allengeorge> I keep getting "syntax error: unexpected {, expecting

15:22 < exch> the 'var foo []string' defines the variable.  it's not
supposed to do initialization, unless you follow it with '= []string{"foo",
"bar"}'
15:23 < allengeorge> Oh...thanks.  For some reason I keep forgetting and
getting hit by this
15:24 < allengeorge> I usually do the :=, and often the var <var_name>
<type> for simple types
15:24 < allengeorge> But for some reason the arrays & maps always trip me up
15:24 < allengeorge> Thanks exch
15:24 < exch> heh it's not very intuitive having so many different ways to
declare/initialize stuff
15:28 < allengeorge> Yes, it can be confusing.  It'd be nice if the language
were pared down a bit wrt.  initialization
15:28 < jessta> 2 ways to declare stuff and 3 ways to initialise it
15:28 < exch> Rob Pike acknowledged that in a recent ML thread.  it seems
they are open to improvements on that part
15:30 -!- visof [~visof@unaffiliated/visof] has joined #go-nuts
15:30 < allengeorge> Actually, aren't there 3 ways to declare stuff?  The :=
does declaration/initialization, you can do var <var_name> <type_name>
= <init_statement>, or var <var_name> = <init_statement>
15:30 < allengeorge> Of course, if you do var <var_name>
<type_name> you can omit the <init_statement> there
15:31 < jessta> you can't do the third one, it needs a type

15:33 < taruti> := seems hard to get right when combined with multiple

15:34 < allengeorge> Although the := with multiple scopes has hit me, I
don't find that so annoying - I can easily see and address the problem

15:34 < exch> That's not been a problem for me personally.  I had to
condition myself to pay attention to it though
15:34 < allengeorge> I like the := the most since I don't have to keep
re-typing-out :) the type
15:35 < allengeorge> Yes, you do have to pay attention
15:36 < allengeorge> I think the var <var_name> =
<init_statement> should be dropped.  I like var <var_name>
<type_name> because I can declare a var ahead of type and assign it later
15:36 < allengeorge> (If dropping one of the initialization is going to
happen)
15:36 < jessta> allengeorge: yeah, good point
15:36 < taruti> so how should global variables be defined?
15:37 < allengeorge> taruti: I don't see the problem?
15:38 < taruti> allengeorge: they typically are of the form "var foo = bar"
and "foo := bar" is not allowed for them
15:39 < allengeorge> Hmm.  That's true - and annoying.  I remember typing :=
in the global scope and being surprised that it didn't work
15:39 < bartbes> that is weird
15:39 < bartbes> wait
15:39 < bartbes> can you execute functions in global scope?
15:39 < bartbes> as in, running stuff, instead of declaring stuff
15:40 -!- Sacho [~sacho@90-154-149-17.btc-net.bg] has quit [Remote host closed the

15:41 < allengeorge> I don't know.  I know you can run functions in the
package init()
15:41 < allengeorge> Which is run in package dependency order
15:42 < allengeorge> I vaguely recall that you can assign the results of a
func call to a const
15:42 < exch> var foo int = calcFoo() in global scope works
15:43 < allengeorge> Ah...interesting
15:43 < allengeorge> BTW, is there a way to pass a type around?
15:44 < allengeorge> I have an unmarshaled JSON object and I'd like to write
a generic function to convert an interface{} into the type I specify
15:45 < allengeorge> The func specification would be something like
getFIeld(jsonMap map[string]interface{}, fieldName string, fieldType ???)
(fieldVal ???, err os.Error)
15:45 < allengeorge> I'm guessing that's not possible without generics
15:47 < exch> You can do it with the reflect package.  the ???  bits wuold
except something like reflect.IntValue or reflect.StructValue
15:47 < exch> It'll require a fair bit of typeswitching and assertions to
get convert your interface{} to the right type though
15:48 < exch> This may be what you are looking for.  My script thingy uses
something similar to resolve struct fields and get/set their values.
http://github.com/jteeuwen/Tinyscript/blob/master/tinyscript/util.go#L35
15:48 < exch> there's a setStructField() and getStructField() function there
15:49 < allengeorge> Thanks exch - I'll take a look at it
15:49 < allengeorge> Yeah, the typeswitching and converting from interface{}
to a concrete type and figuring out what's in an interface{} is not my favourite
part of Go
15:50 < allengeorge> I'm not a fan of that although I haven't worked enough
with Go to see a better alternative
15:51 < exch> It works, but it's a lot of work, if there are a lot of
different possible types it can hold.  They did greatly simplify the reflect
package recently though.  There used to be a reflect.xxxValue for every type
explicitely.  Which made for a very lenghty switch statement :p

15:53 -!- ronnyy [~quassel@p4FF1DC5C.dip.t-dialin.net] has quit [Remote host

15:54 < allengeorge> Doesn't that create problems when you want to convert
into a concrete type though?
15:55 < exch> I haven't gone through all the changes in the reflect
packages, but I believe there's now a Type field somewhere in there that holds an
integer constant telling you exactly what you are dealing wit..  int8, int16, etc.
You can use that to further finetune the type assertion
15:55 < taruti> reflect.Typeof(foobar) -> Type
15:55 < allengeorge> Ah, ok.
15:56 < exch> Which basically requires even more typing cos now you have to
deal with nested switch statements, but I guess there was a reason for that :p
15:56 < allengeorge> Yeah :)
15:56 < allengeorge> See, in my case I'm writing a state machine that has to
deal with multiple message types that share a common interface
15:56 < exch> That would mean a typeswitch then..  with a case for each
possible message type
15:57 < allengeorge> Yeah.
15:57 < allengeorge> Now that I say it, a better approach might be the
"Command Pattern" (!)
15:57 < allengeorge> Each message has a handle func that does the
appropriate dirty work, but then each message would have to know about the data
inside my state machine
15:58 < allengeorge> I'm also doing JSON marshaling and unmarshaling, and I
don't want to use the stock unmarshal/marshal representation

18:15 < araujo> exch, there?
18:16 < exch> yes
18:17 < araujo> exch, I have a variable of type interface{} , but seems that
the type assertion is not working with it
18:18 < exch> is there a prticular error you are getting?
18:18 < araujo> it is actually a value returned from the (p *Vector) Pop()
interface{} , method
18:18 < araujo> nothing at all, just the "ok" clause is not executed
18:18 < araujo> ...
18:19 < araujo> oh, and the var contains a pointer type of a user defined
type
18:20 < exch> You need to cast it to a pointer type.  if v, ok :=
myvar.(*MyType); ok { }
18:20 < exch> MyType and *MyType are 2 distinctly different types
18:22 < araujo> correct, correct
18:22 < araujo> mm...
18:22 < exch> http://go.pastebin.com/xMa1xTEM
18:22 < araujo> it is what i doing here...
18:23 < temoto> When two goroutines access same int variable, like go func()
{ shared += 1 } ; go func() { shared -= 1 } is that uhm..  safe?
18:23 < exch> araujo: it's still not working?
18:23 < araujo> exch, yeah :(
18:25 < exch> hmm.  it should really.  Can you put something like
'fmt.Printf("%T\n", val)' in there somewhere?  it'll print the actual type, so you
can make sure you are trying to cast to the correct one..  Just for debugging that
is

18:30 < exch> temoto: not entirely sure, but i'd say that is not safe.  Go
uses channels for synchronized access to data between goroutines.  You can also do
manual synchronisation by using a sync.Mutex
18:31 < jhh> not even "foo = bar" is safe if they are larger than one 32 bit
i think
18:37 < temoto> exch, the thing here is that i don't need synchronization
(as in someone waits another), i need atomic increment/decrement.
18:37 < KirkMcDonald> temoto: In what sense are these different?
18:40 < temoto> KirkMcDonald, well, i don't care on operations order to the
line that parallel is fine, as long as i observe correct (not garbage) value at
any point in time.
18:40 < KirkMcDonald> The purpose of a mutex is to ensure that an operation
is atomic.

18:41 < KirkMcDonald> temoto: Go does not necessarily guarantee this.
18:42 < temoto> KirkMcDonald, okay, thanks.
18:42 < temoto> I wonder shouldn't compiler issue a warning about it, then.
18:43 < KirkMcDonald> You want the compiler to detect when multiple
goroutines access the same memory?
18:44 -!- allengeorge [~allengeor@74.12.150.7] has joined #go-nuts
18:46 < temoto> Well at least same name would be helpful.
18:47 < temoto> Doing it for same memory is hard, i guess.
18:49 < KirkMcDonald> I think that the "multiple goroutine" part is hard,
too.
18:50 < KirkMcDonald> for { go foo(); if rand.Intn(2) { break; } }
18:54 < temoto> If compiler can prove that foo is only used with 'go', then
anything in it is "in different goroutine from any other code".
18:55 < temoto> And for this warning, it only needs one 'go'.

19:20 < allengeorge> Maybe (probably) there's something I'm not
understanding
19:21 < temoto> allengeorge, like a, err := foo(); b, err := bar() ?
19:21 < allengeorge> temoto: Yeah.  I have an example here:
http://gist.github.com/502514
19:21 < allengeorge> The err returned back to the main function is nil, even
though an actual err is returned by getUint64MessageField
19:21 < temoto> allengeorge, you can't declare (:= is implicit declaration
and definition) a variable twice.
19:22 < allengeorge> Well heartbeatVal wasn't declared before
19:22 < allengeorge> I thought that you can do multiple left-hand vals and
only the ones that have _not_ been declared before will be declared
19:22 < temoto> allengeorge, ah that, you have different issue.  It's
related to named function return values.
19:22 < exch> allengeorge: that rule does not apply when you are inside a
new scope
19:23 < allengeorge> Seriously?!
19:23 < exch> the switch case is considered a new scope in this case.  Which
means it's perfectly valid to redeclare err
19:23 < exch> Not sure what the logic in that is, but it's been covered a
few times before
19:23 < allengeorge> Ouch
19:23 < allengeorge> I totally didn't expect that
19:24 < allengeorge> I'll search the ml for this, but IMO that's really
surprising
19:24 < exch> same goes if you do this: if v, ok := foo(); ok {} where ok or
v has been defined before..  the if statement constitutes a new scope level
19:24 < temoto> allengeorge, your case is funny because for correct work you
should expect error at , err :=
19:25 < allengeorge> Yeah - maybe a warning like "redefining function return
variable" would be useful
19:25 < temoto> allengeorge, so to fix it, you could declare first value and
use foo, err = get...()
19:25 < allengeorge> exch: I didn't think about that
19:26 < temoto> allengeorge, or foo, err1 := ...
19:26 < allengeorge> temoto: Yeah.  Hmm.  I'll have to be more careful about
my use of := now
19:26 < exch> what temoto says should work.  I always declare any such vars
either in the return value of the func, or at the top of the func as var err
os.Error..  And then only use = instead of := in function calls
19:27 < exch> Granted though, this is not very intuitive behaviour and I'm
hoping it'll get addressed at some point..  or at least yield compiler warnings
19:27 < allengeorge> exch: I did that, except one of my variables on the
left hand side wasn't declared in advance, so I assumed that only it would be
affected by the :=
19:27 < exch> Yea, outside a new scope level that would be true
19:27 < exch> Which is what makes this confusing :p
19:28 < allengeorge> Which, as I'm finding out now is not the case :)
19:28 < temoto> goinstall code.google.com/p/goconc what's wrong with it (hg
repo)?
19:28 < temoto> says unknown repository
19:29 < exch> allengeorge: in the immortal words of General ackbar: It's a
Trap!
19:30 < allengeorge> exch: ! That explains where I got that idea from; when
I wrote some early code I got a warning saying (I'm paraphrasing) that "at least
one variable to left of := must be new"

19:31 < allengeorge> temoto: it's working for me (a straight hg pull)
19:31 < allengeorge> I mean, clone
19:32 < allengeorge> exch: Yeah - a pretty scary trap.  I realize it's tough
when designing a language, but this seems like a serious issue
19:32 < temoto> allengeorge, i'm trying to use goinstall from the point
where they told me it can handle clone/make/install boilerplate for any url.

19:34 < allengeorge> temoto: it works if I do goinstall
goconc.googlecode.com/hg/
19:35 < allengeorge> Or at least it appears to work; puts the objs etc.  in
$GOROOT/src/pkg/goconc.googlecode.com/hg/
19:35 < allengeorge> I don't really use goinstall; haven't been using a lot
of 3rd party libs yet - I'll have to do that soon though
19:35 < temoto> allengeorge, thanks.
19:37 < allengeorge> np
19:37 < exch> goinstall still needs some work imho.  it doesn't use
makefiles that come with the project.  It makes most of my own packages useless in
a goinstall context
19:37 < allengeorge> Hmm.  That sounds broken
19:37 < exch> yes
19:38 < exch> It builds it's own makefile by scanning all .go files in the
projects base directory.  That doesn't really work for my stuff
19:39 < exch> It also makes the usage of goinstall for cgo projects a bit of
a pain.  They usually have extra stuff defined in the makefile required for proper
linking of c libs
19:39 < allengeorge> Yeah - what happens if you have subdirectories, and the
files in the main dir have dependencies on those in the subdirectories?
19:39 < exch> allengeorge: the build fails
19:40 < exch> you'll have to go into the project dir and run make anually
19:40 < allengeorge> Again, doesn't seem like expected behaviour; I guess
it's only for simple packages, which is fair

20:47 < exch> The scoping behaviour with := seems to have an additional
oddity.  Pay attention to the definition of v in the if-statement at line 18.  v
should go out of scope when exiting the if blocks, yet it's used without problem
at line 23.  http://github.com/kless/freecrypto/blob/master/twofish/math.go#L18

20:56 < allengeorge> In Ruby AFAIK there are no if-block scopes etc.  - I
think the smallest you can go is method level and then {...} level
20:58 < exch> I don't mind of Go is very particular about it's scoping, but
if it considers if blocks a new scope, the bahaviour in the file above should not
be allowed

21:01 < KirkMcDonald> exch: D addressed this problem by defining blocks that
introduce a new scope and blocks which do not as separate productions in the
grammar.
21:03 < exch> It seems go blocks are now behaving as both simultaneously

whatever the language designers pick, be it Ruby or Go or whatever
21:08 < exch> exactly
21:08 < allengeorge> But I think these weird corner cases introduce subtle
bugs and detract from the overall feel of the language

#go-nuts
21:16 < exch> ha!  As it turns out, the code in that particular github repo
will not compile.
21:17 < exch> for exactly the reason we expect it to fail.  the v
definitions are considered independant of the toplevel scope and this the usage of
v after the if blocks is invalid.
21:17 < exch> That's a relief really.  Turns out Go is consistent afterall
21:18 < allengeorge> My world makes sense ;)
21:18 < exch> yay :)
21:18 < exch> Shame though.  i was about to post a mailinglist thread on it
with a beautiful analogy to schrodinger's cat :(
21:19 < allengeorge> I'm sure there will be plenty of opportunities; Go is
still young
21:20 < exch> perhaps I should just try to run any questionable code next
time, before I start writing rants about it :p
21:20 < exch> true
21:20 < allengeorge> Well, it's tough - I generally assume that code on a
public repo is compilable
21:21 < allengeorge> With git, I have private local branches that aren't,
but I don't push anything to origin/master unless it compiles
21:22 < exch> I try to make it usable, but with go's rapid development that
can be a challenge.  You have to keep updating existing repos with any API or
language changes.  But I guess that's the price we pay for using something that
isn't finished yet :)
21:22 < exch> I also don't have access to private repos, so anything I put
on their for personal use is available to everyone
21:23 < allengeorge> You can have a private branch on your local machine
21:24 < allengeorge> So you may be developing a lot locally but only push to
the master when it's compilable
21:24 < exch> true, but I switch computers regularly.  I use github as a
remote harddrive :p
21:24 < allengeorge> Ah - I understand.  I usually just add my other
computer as a remote in git
21:25 < allengeorge> As long as the machine is up I fetch from the remote
(aka the machine I was working on) and continue developing
21:26 < exch> hmm haven't considered that yet.  I do have a server running
at home.  I could try configuring that as the repository for private stuff
21:27 < allengeorge> Yeah.  It's very simple.  You don't even have to set up
a server per-say.  If it's a linux box and the dir with the git repo is shareable
you could do git remote add <box_name>:/<path_to_repo>
21:27 < exch> nice
21:27 < allengeorge> As long as it's ssh accessible you're good to go
21:27 < exch> it is
21:28 < temoto> erflhtvktn
21:28 < allengeorge> Cool - then you should give it a try some time

there as well.
