11:54:31reactormonkDoes doc have a typechecked AST?
11:54:51*[CBR]Unspoken quit (Ping timeout: 256 seconds)
11:57:33Araqwhether you have a typechecked AST or not is the 'n.kind == nkSym' check
11:58:15Araqfor doc2 it has a typechecked ast, for 'doc' it has not
11:58:32Araqso you need to check it at runtime because the same code is used for both
12:00:14reactormonkHm, sounds ugly, but eh. What do we still need doc2 for?
12:00:17reactormonkehh doc
12:01:15reactormonkAraq, btw, what do you think of using var/non-var overloading for in-place modification/copy?

12:51:35Araqboop: create a bug report please
12:51:41Araqvery easy to fix
12:51:50bogenAraq: For the JS backend the reason callbacks to closure forming local functions is working is because the function definitions were generated in place (nested). Since JS fully supports closures, it all "just works" without support from the Nim JS codegen.

16:15:23Learath2the callback is normaly expected to have 2 parameters but that seems to make it carry a third around
16:15:49*EXetoC joined #nim
16:17:58*filcuc quit (Quit: Konversation terminated!)
16:36:46Learath2apparently its called an anonymous procedure and i had to dig alot to find what it was :P
16:40:42federico3can the SDL2 load an opengl "model" from file?
16:40:48fowlLearath2 a closure
16:41:46fowlfederico3 theres no such thing as an opengl model, assimp is a library that can open just about anything
16:43:00fowlfederico3 it only loads the model data, theres an example of how to send it to opengl
16:48:39boophmmm - how should i handle GC in procs that are called by C?
16:49:08boopactually back up- http://hastebin.com/ecadoyecuf.rb
16:49:21boopwhat's this? i'm thinking i've run out of memory or something but i'm not sure
17:15:11boopthat's after 30 calls from outside nim, if i use markAndSweep GC it gets as far as 1360 before spitting out the same error
17:21:26boopand v2 gets to 27
17:21:27boophm hm
17:22:34reactormonkAraq, the var version could return as well
17:22:51*Trustable quit (Remote host closed the connection)
17:23:52federico3fowl: thanks
17:24:50reactormonkso we could do chaining as well, and have some macro that simply calls a copy constructor and creates a non-var version of the proc
17:27:42Araqreactormonk: no no no no.
17:28:58Araqboop: depends on what you're doing
17:29:03reactormonkHum, not sure how to do the types part... the non-functional design makes it hard to hook code in - just create lots of data along the side and merge them at the end?
17:29:23boopAraq: digging around...
17:29:44reactormonkaka n.sym == nkSym etc. and if true, add it to a list, then return that list at the end of genItem to create a global index?
17:29:58boopi have this type which is an ref to an object which is just contains a seq[string] and a StringTableRef
17:30:07boopand a proc that creates that from a string
17:30:19boopand i'm calling a proc from outside nim that calls this proc
17:30:31boopand.. that seems to be enough to mess it up, given enough iterations
17:30:58reactormonkah, the indexfile works via rst - hmm.
17:31:32Araqboop: did you read this http://nim-lang.org/docs/backends.html#backend-code-calling-nim-nim-invocation-example-from-c ?
17:31:45reactormonkAraq, why the aversion on var overload?
17:32:15Araqreactormonk: var x = chomp(y) # modifies 'y'.
17:32:27reactormonkAraq, ... yup.
17:32:35Araqvar x = chomp("hello\n") # doesn't modify "hello\n"
17:32:58reactormonkthat's static eval anyway?
17:33:04reactormonkaka at compiletime
17:33:44Araqso the behaviour depends on the var-ness of the passed argument. that's just silly.
17:33:48boopAraq: huh nope, never seen that... i'm doing -app:lib and not using --noMain or --noLinking, would that make much of a difference?
17:33:51boopand not exporting a header file
17:34:25Araqboop: well if you don't setup Nim's GC properly from GC then don't expect things to work
17:34:32Araq*from C
17:34:38*boop nods
17:34:43reactormonkYup, and that sounds good to me. Maybe add a proc c[T](c: var T): T that creates a non-var version of a variable for chaning
17:34:47boopdoes that just entail calling NimMain()?
17:35:14Araqaccording to the docs yes. I'm not so sure
17:35:26Araqreactormonk: that's awful.
17:35:27boopi was reading the stuff here http://nim-lang.org/docs/manual.html#foreign-function-interface
17:35:30boopi'll give it a shot!
17:36:27reactormonkAraq, an ide can highlight you var vars and let vars correctly, so it should be easy to see
17:37:55Araqreactormonk: contrary to what you might believe, I don't start with a bullshit design and then use IDE technology to patch over it
17:38:06boopAraq: seems to work a treat! thanks :)
17:38:18boopmight be worth adding a note to that manual section, though.
17:40:45Araqvar x = "foo"
17:40:53Araqecho($x)
17:40:58Araqvar y = 90
17:41:14Araqecho($y) # overloading used to get the *same* behaviour.
17:41:20Araqvar x = "foo"
17:41:24Araqecho chomp(x)
17:41:32Araqlet y = "foo"
17:41:49Araqecho chomp(y) # overloading used to get ... something else
17:43:12reactormonkvar z = $x # same string?
17:43:17Araqboop: I recently re-discovered that piece of documentation
17:43:25Araq;-)
17:43:27boophehe
17:44:39reactormonkThe overloading on var/non-var is orthogonal to type overloading - the type overloading should adhere to the same behaviour (which we can set in stone via concepts if I ever get to them - I'll take a look at that instead of doc I think.)
17:45:06reactormonk... and with var/non-var overloading, it's a differen behavior, because it's a different kind of overload.
17:45:55Araqwhat is the problem anyway? you cannot accept chomp vs strip? aka different names for different things?
17:46:41reactormonkIt's more of a streamlining idea
17:46:59reactormonkOr we can just go for "chomp" and "chomped"
17:47:56reactormonkbut chomp/strip is just ugly, have fun finding the other in the docu
17:48:43Araqwe could add cross references in the docs
17:49:11Araqor we could simply accept the fact that a strutils with a chomp is not suddenly worse than a strutils without a chomp.
17:50:12Araqor maybe it is worse and we should reject the PR.
17:51:38reactormonkjust checking - none of the two procs have var arguments - so our argument can't really apply to that PR
17:51:50reactormonks/our argument/our discussion/
17:52:12AraqIMO chomp should take a var argument and there should be no non-var version.
18:03:22wuehlmausbtw: in perl there was chop which cuts away the last letter or a white space and chomp which only does the latter
18:05:21wuehlmausactually there still is both chop and chomp
18:06:32wuehlmauswhitecase is not correct, chomp deletes a newline
18:14:46*onionhammer joined #nim
18:16:33renesacstrip and striped would be the best I guess, but backwards incompatible
18:26:52wuehlmausfor me chop is better than chomp

18:37:07federico3renesac: adding a keyword to strip? chars="abc" removes any of those chars, str="foo" removes the exact string

19:08:23renesacfederico3: the distinction between strip and striped would be if it returns a new string or do it in-place
19:09:07renesacbut yeah, I just commented on the PR that maybe we can have a strip that accepts an string too
19:26:07reactormonkAraq, huh? options only goes for typetraits
