13:20 greghendershott: If using syntax-parse with define-splicing-syntax-class, is there a way to still get at the original, "raw" syntax?
13:20 greghendershott: I ended up using nested syntax-parses. First gets the "raw", second breaks it apart further.
13:21 greghendershott: Which works, but I'm wondering if I'm overlooking something obvious.
13:21 asumu: greghendershott: can you use an ~and pattern?
13:22 greghendershott: You mean (~and foo.class alias), and alias would be the original "raw"?

19:27 neilv: now that i'm documenting the gnu parted library i wrote a while ago, i wish i'd kept my notes about struct field types up-to-date.  offhand i don't remember whether some of these are integers rather than reals, nor which can be #f
19:30 jonrafkind: should be easy to throw in contracts right
19:30 neilv: i was using typed-racket at one point, but there was some problem, so much of the code has commented-out tr types that are a little out-of-date
19:31 neilv: i guess i could use internal contracts. it's not performance-sensitive
19:32 (join) rico_
19:33 neilv: i don't think mcfly yet sucks in contracts for structs; unless/until it does, the code will look even sillier, with each struct being written 3 times in slightly different format
19:33 neilv: at some point, i have to ask myself why i'm not just using haskell :)

19:56 yoklov: i will never understand why (send bitmap-dc get-pixel) takes a color, modifies it, and returns a boolean.
19:57 yoklov: it's just such an awkward api
19:59 (join) ewemoa
19:59 neilv: yoklov: my first guess is that it's an artifact of old wxwindows, and in the c/c++ code, was intended to avoid mallocs for an operation that can happen a lot
19:59 asumu: That's why a lot of the editor API in Racket uses box arguments too.
19:59 ewemoa: neilv: does adding the following to quack.el seem sensible? (put 'match-let            'scheme-indent-function 1)
20:01 yoklov: that's probably the reason, but it'd be very nice to have a higher level option

20:51 ewemoa: is it just me or when i use quack, does the coloring / theming in emacs mutate?
20:53 (join) jao
20:53 (quit) walter|r: Ping timeout: 246 seconds
20:53 neilv: quack predates emacs themes. it uses font-lock.  iirc, it doesn't mess with font-lock faces, so it shouldn't mess with other modes
20:54 neilv: quack is in minimal maintenance mode. i have a replacement that is not quite ready for release
20:55 ewemoa wishes neilv smooth progress on his replacement :)
20:57 (quit) jonrafkind: Ping timeout: 252 seconds
20:58 neilv: work on replacement (meow) is stalled. am working on rackout right now
20:59 ewemoa: good luck with rackout then :)
20:59 neilv: thanks
21:06 cky: neilv: That command could work very well...when you're running Racket off a RAM disk. ;-)
