00:17 < |Craig|> You get issues like that if you have some object files from
an old version of go
00:18 < nsf> has anyone tried using new cgo in gc tip?  is it ready to use
or should I wait for the release?

01:56 < uriel> ah, seems neat, but I'm not sure that belongs to gocode

04:15 * TheSeeker works on maintaining a small MMO game client written in C/C++ (I
shouldn't be let near code, but I'm willing to work for almost nothing, so...)
04:16 < TheSeeker> it was poorly written in teh first place, so everyhting's
interconnected.  can't change much of anything without 30+ minutes recompiling :|

04:20 < TheSeeker> Once I finally get done adding/debugging the features
I've been working on for months now, I'm tempted to try and make a Go clone of the
client with Go-OpenGL >_>
04:21 < nsf> Go-OpenGL is broken for some nvidia drivers on linux
04:21 < nsf> well..  kind of broken
04:21 < TheSeeker> And I'm on windows :)
04:21 < nsf> http://code.google.com/p/go/issues/detail?id=1262
04:21 < nsf> maybe in windows too, I don't know
04:22 < nsf> i'm just saying
04:22 < nsf> if people will annoy you with bug reports later :) keep in mind
that there is an issue
04:22 < TheSeeker> I've only barely started trying to get go-SDL to compile,
haven't even really tried Go-OpenGL yet...  need to figure out howtf to get my
environment set up.  :)
04:24 < TheSeeker> Biggest issue is that I don't have access to net layer
sources for the client, just dlls and header files.  so I'll need to learn how cgo
and/or swig works if I want to actually talk to the server...
04:26 < nsf> cgo is pretty simple
04:27 < nsf> swig is much worse (imho)
04:27 < nsf> it's not like the support for Go is bad, using it is much
harder

11:08 < KBme> how do you call it?  can you paste it?

11:09 < xash> That's the call

11:09 < xash> No
11:10 < xash> func (f *Field) addCounter(x, y int) {
11:11 < Namegduf> That's not called "f.addCounter"
11:11 < Namegduf> It's called "addCounter"
11:11 < Namegduf> Or possibly something else, I'm not sure how it works with
methods.
11:11 < KBme> yeah, the issue is probably the fact it's a method
11:11 < Namegduf> At any rate, receiver.method is not passing the method.
11:12 < KBme> i don't know either :-/
11:12 < xash> Ah, yes, makes sense
11:12 < Namegduf> Since it's lower case and internal to a package as a
result, I'd suggest just using a function.
11:12 < KBme> maybe you'd need func myfunc(foo int, recv thereceiver, f
func(..))
11:12 < xash> Well ..  but gives "addCounter undefined" error
11:13 < Namegduf> KBme: As it itself is a method on *Field, I assume it
already has the receiver
11:13 < KBme> oh right so you do f.f ;)
11:13 < Namegduf> xash: There's probably some way to use it, but I don't
know what the syntax is.
11:14 < Namegduf> A cheap solution is to just use a function.

11:39 < hokapoka_> I'm trying to unmarshal some json, from one of the google
apis.  There's a datetime property that contains : 2010-12-15T03:56:26.650Z when I
use time.Time as the propery type causes the json Unmarshal to error.
11:40 < hokapoka_> Any suggestions on how I should overcome this?  The only
solution I can think of is to create a func to parse the value whenever I need to
reference it.
11:40 -!- Jurek [~Administr@46-129-41-134.dynamic.upc.nl] has joined #go-nuts
11:41 < KBme> yeah, i think unmarshaling only works with builtin types
11:41 < hokapoka_> Well, rather than everytime I reference it, more after
the parsing has compleated run through and re-parse all the dates.
11:41 < KBme> you could also post-process it
11:41 < KBme> yep
11:42 < KBme> maybe you can modify the codec or whatever but i don't know
how that works
11:42 < hokapoka_> IIRC there's no get/set in go right?
11:43 < KBme> for what?
11:45 < hokapoka_> If I had a property Date_ of type time.Time and then Date
of type string.  Date_ could be a get{ return parse(Date) } where parse returns
the Date in time.Time format.

11:48 < Jacek> ...  or err1.(Error).Timeout()
11:48 < Namegduf> That's not a method name.
11:48 < Namegduf> It's a type assertion.
11:49 < hokapoka_> KBme: rather than passign all the date after the json has
been unmarshalled It oculd be done on demand.  of couse I would cache the value
once it had been passed so the next time it used the prev value is returned.
11:49 -!- wrtp [~rog@92.17.39.62] has joined #go-nuts
11:49 < Jacek> Can I use to to convert os.Error into os.Errno?
11:49 < Namegduf> someinterface.(type) == Convert that interface value to
<type>, where <type> is the type inside it.
11:49 < Namegduf> You can use x, ok := someint.(type) notation to see if
(type) is what is inside it.
11:50 < hokapoka_> KBme: Just wondering waht my options are reeally.  I
think like you said tho, parse the data values after it's been unmarshelled is the
best option.
11:50 < Namegduf> Assuming os.Errno is a type implementing os.Error
11:50 < Namegduf> Yes
11:51 < Jacek> Thank you.  I need some time to think about what you've told
me.
11:52 < Namegduf> It's basically a way to extract the original value from an
interface.
11:52 < Namegduf> The version without ",ok" panics if the interface does not
contain a value of that type.
11:52 < Namegduf> The version with ",ok" can be used as a test.
11:56 < wrtp> can anyone see why this program doesn't catch the panic?
http://pastebin.com/HPw940y0
11:56 < wrtp> at least, it doesn't for me
11:57 < wrtp> it works ok for catching a divide by zero error or another

11:57 < wrtp> i think it's probably a bug, but i wanted to check before

11:58 < Namegduf> Is a panic occurring?
11:58 < wrtp> yeah, i just get a traceback

14:35 < hokapoka_> From here: http://golang.org/src/pkg/time/format.go#L48
14:35 < hokapoka_> oic
14:37 < hokapoka_> The time format is comming from one of google's apis,
they all appear to have that time format in their JSON data.
14:37 < wrtp> go time format doesn't currently support sub-second times
14:37 < wrtp> that's interesting
14:37 < wrtp> that's a good use case
14:37 < hokapoka_> yes, I thought that was the case.
14:37 < hokapoka_> indeed
14:38 < hokapoka_> I just wanted to beable to pass the string and tell it to

14:40 < wrtp> it would be better if it parsed it

14:43 < hokapoka> ATM I'm having to unmarshal the data and then reparse the

14:45 < Namegduf> hokapoka: time.Time would need to implement the

14:46 < Namegduf> From your perspective, an option would be to wrap
time.Time in your own type, which does implement that interface.
14:46 < wrtp> yup
14:46 < wrtp> it's easy to do
14:47 < Namegduf> Maybe you could make time.Time an anonymous field of your
type, which should make your type behave like it but extended.
14:47 < Namegduf> I think.

17:40 < exch> If you want unbuffered stdin/out, you will probably have to do
some syscall magic
17:40 < temoto> I want line-buffered mode.
17:41 < exch> stdin is line buffered by default
17:41 < temoto> stdout?
17:42 < exch> should be as well, but tbh, I have never checked of it is
17:43 < exch> If it isn't, you will probably have to direct output to your
own buffering routine and only flush to stdout when a line is complete
17:44 < temoto> Can't i control buffer size as well?
17:45 < exch> In your own buffer routine, sure.  have a look at
http://golang.org/pkg/bufio/
17:45 < temoto> No, i mean in os.Stdout.Write
17:46 < exch> Write() just writes whatever you give to it

18:02 < nsf> yes
18:02 < exch> it's possible.  I really have no idea
18:03 < nsf> os.File's Write calls syscall.Write directly
18:04 < nsf> and if one wants it buffered, you use bufio
18:04 < nsf> although it doesn't call Flush automatically
18:04 < nsf> on line breaks etc.

20:40 < temoto> Is for _ = range ch {} a proper idiom to wait until channel
is exhausted?
20:41 <+iant> that will wait until the channel is explicitly closed
20:41 <+iant> it is fine for that
20:42 < temoto> Oh that explains why i had some deadlocks before.
20:43 < kimelto> you still have to manage the closed() logic in a select()
right?  or is select aware of closed channels and does not re try to read from
them?
20:43 -!- Fish- [~Fish@9fans.fr] has joined #go-nuts
20:44 <+iant> there can't be anything to read from a closed channel in a
select, so that case will never be selected
20:44 <+iant> I mean, assuming you have read all the buffered data
20:45 < temoto> How to properly write this: spawn N threads, wait until all
are completed?
20:45 < nsf> temoto: in Go there are no threads :)
20:45 <+iant> have each goroutine write to a channel, wait until you have
received N pieces of data
20:46 < temoto> for done_count < N { <-done_ch } ?

20:47 < temoto> nsf, is there a conceptual difference?
20:47 < nsf> yes

20:47 < nsf> well, conceptual no
20:47 < temoto> Okay.
20:47 < nsf> practical - yes
20:47 < temoto> What is practical one?
20:48 < nsf> goroutines are scheduled by go runtime and not by underlying OS
20:48 < temoto> Well i didn't say OS threads either.
20:48 < nsf> ok then
20:49 < kimelto> what is the proper strategy to exit a for{} loop in case
that all channels of a select have been closed?
20:49 < temoto> O_O
20:50 < kimelto> iant: the spec talk about nil channel, not closed channel.
20:50 < temoto> kimelto, break?
20:50 < kimelto> and closed channels return zero...
20:51 <+iant> kimelto: you're right, I may be confused
20:51 < kimelto> temoto: right, but the question is on which condition to
break
20:51 < temoto> kimelto, select {...} break
20:52 <+iant> kimelto: select does return closed channels as ready
20:52 <+iant> so I guess the case has to consider that possibility
20:52 -!- dju [dju@fsf/member/dju] has quit [Quit: Quitte]
20:52 < kimelto> iant: so I wonder if you have to test for closed() in a

20:52 < temoto> kimelto, with continue in each other select branch
20:52 < InaVegt> Hrm...  is Go interoperable with GWT?
20:53 <+iant> kimelto: yes, something like that
20:54 < kimelto> temoto: you mean for { select {...} break } ? that's a do
{..} while(0) loop!

21:02 < kimelto> :/
21:03 < temoto> kimelto, i don't think you need to nil channels in

21:04 < kimelto> the point is that a closed channel always return zero.
21:04 < temoto> Don't close then?
21:04 < temoto> http://pastebin.com/3dAWT70Q

21:26 < kimelto> that works like a charm when you only have 1 channel.  one
