00:31 (quit) dnolen: Quit: dnolen
00:31 neilv: do all the core racket developers agree with that, or does someone have incriminating office christmas party photos to silence the dissenters?
00:42 asumu: neilv: It's in the style guide.
00:43 asumu: http://www.ccs.neu.edu/home/matthias/Style/style/Choosing_the_Right_Construct.html#(part._.Definitions)
00:43 neilv: i believe that's the style guide for core racket developers, not for racket developers in general
00:43 asumu: Oh, I thought that's what you were asking.
00:44 rudybot: http://tinyurl.com/cfoef3d
00:44 asumu: I don't know if everyone agrees on it, but I don't think it's an inviolable rule anyway.
00:44 neilv: it's easier to say "on this project, do things this way" than "this is the best way to do it everywhere"

00:53 jonrafkind: i prefer internal definitions to let
00:53 jonrafkind: let makes me feel like i time traveled to 1962
00:53 (quit) jrslepak: Quit: This computer has gone to sleep
00:53 neilv: that was lsd, not let
00:54 jonrafkind: the only real use I have for let these days is to create a new internal definition context since (begin ...) doesn't do that
00:59 asumu: I have been tricked by internal defines though when I've tried to shadow bindings but instead made undefined values.
01:00 asumu: So it's not always better than let in that sense.
01:10 jonrafkind: you mean (define x ...) ... (define x ...) ?
01:15 asumu: (let ([x 3]) (let ([x x]) x))
01:15 asumu: which doesn't work so well with define.
01:16 jonrafkind: yes but you are using that to update the variable x right?
01:16 jonrafkind: (define x 0) (define x (+ x 1)) or something?
01:16 asumu: Yeah.
01:16 jonrafkind: I would just use set!
01:19 asumu: That would work, but not if the second define was in an inner context and I want the original in the outer context.
01:20 asumu: I'm sure I could avoid this in most cases though, so it's not a big deal though.
01:21 mithos28: jonrafkind: you are working on honu right? Is it in a semi-usable state?
01:21 jonrafkind: yea
01:21 jonrafkind: https://github.com/kazzmir/Honu/blob/master/pong/pong.honu
01:22 jonrafkind: skyrim!
01:22 jonrafkind: i mean.. pong!
01:22 (quit) jeapostrophe: Ping timeout: 240 seconds
01:22 jonrafkind: if you are willing to set up the racket-allegro bindings (and the allegro librariy) you can play it
01:23 mithos28: nice, is there any documentation?
01:23 jonrafkind: yea there should be some in 5.2, but its sort of bare
01:24 jonrafkind: it should appear in the "experimental" section of the docs
01:24 mithos28: ok, http://docs.racket-lang.org/search/index.html?q=honu gives me a blank page
01:24 jonrafkind: yea its not on the onlien version yet
01:24 jonrafkind: hm im not sure why actually
01:24 asumu: Do you have both // and # style comments?
01:24 jonrafkind: yea, and nestable /* */ too
01:25 mithos28: awesome on nestableness
01:25 jonrafkind: hell yea
01:25 mithos28: I hate that I cannot comment out sections of code with those comments in other langugaes
01:25 asumu: Yay no more #if 0 comments. ;)
01:26 jonrafkind: some of that pong code was copied from a python implementation which is why there are a lot of #'s in there
01:26 jonrafkind: well I wrote some # style comments too I guess
01:26 jonrafkind: oh ill add a screenshot at least
01:26 mithos28: is the class form in the pong example, the racket/class library?
01:27 jonrafkind: yea, but it only allows variables and public definitions
01:27 jonrafkind: for now
01:27 jonrafkind: if you wanted to actually use it I could add more stuff
01:27 asumu: Does it allow subclassing? (as mixins in particular?)
01:27 jonrafkind: I just use the racket stuff so its only a matter of syntax
01:28 jonrafkind: any racket macros I have to re-implement in honu
01:28 jonrafkind: it currently does not syntactically support subclasses or mixins
01:28 mithos28: I actually wanted to try to make a DSL for llvm. I have bindings for it already but the sexp syntax I am playing with is not nice.
01:29 mithos28: I knew honu was supposed to allow infix and other standard C style stuff which maps better to the concepts that the DSL is supposed to support
01:29 mithos28: since most of the llvm code I have written and I think people will write with the DSL is mathy
01:30 jonrafkind: yea if you want to try honu out that would be great
01:30 jonrafkind: right now im just doing random stuff with it
01:30 mithos28: ok, I'll find where it is broken
