01:15 jonrafkind: you mean how pressing up does nothing?
01:16 jonrafkind: probably because process-key-event is never used
01:17 jonrafkind: you should somehow merge move-rocket, process-key, and process-key-event

01:34 Blaze9: Yeah, that's exactly what I mean. How do you recommend we go about merging those three?
01:36 jonrafkind: well move-rocket checks the key event to see if its right/left, process-key-event checks to see if its up
01:36 jonrafkind: so already you can merge that into a single cond
01:42 Blaze9: Ok, so do you know why process-key-event is never used? Even though I am pressing up?
01:43 jonrafkind: where in the code do you think process-key-event is being called
01:45 Blaze9: Duh... This is what coding at 2AM does. Thank you.

01:54 jonrafkind: i guess its under construction

14:30 stamourv: neilv: :D
14:30 stamourv: What's new?
14:31 neilv: indent and fontify for the submodule forms
14:32 neilv: quack is only just barely being maintained, til meow is finished
14:33 stamourv: I'm looking forward to meow.
14:35 neilv: me too. i think when i left off it only needed another person-day of work (finish the indent algorithm i'd just figured out) before i could do a semi-useful release. now i have to refresh my brain with where i left off
14:41 chandler: If only those darned customers didn't get in the way, we could all be so productive.
14:41 (part) bmp
14:42 neilv: you know how emacs makefile-mode colors tabs and spaces prominently, when it thinks you got them wrong? i plan to have meow do something analogous whenever the indentation on a line does not match what meow would do
14:42 neilv: could be really annoying
14:43 chandler: ooh, that's interesting.
14:43 neilv: type an open-paren, pause for an instant, and all of a sudden all the indents for the rest of the file are magenta bars
14:44 neilv: but could be really useful if you're editing code (without structural editing commands), and want to know when you've closed parens to what they were before
14:44 chandler: I have to say that online expansion has me hooked on DrRacket again...
14:44 neilv: yeah, i've been using drracket a lot
14:45 chandler: It does a nice little marker on the right side of the editor when there's a syntax error. It's helpful and subtle.
14:45 neilv: although, until i have submodules, i have this one library that is split across several files, and i found that i was having writer's block. i eventually realized that was partly due to trying to edit several files at once in drracket
14:46 chandler: Yes, an interactive switch-tab kind of command (keyed off C-x b?) would be nice.
14:46 chandler: And I still miss paredit.
14:46 neilv: there was a paredit-like thing for drracket, done about the same time. divascheme or something like that
14:47 chandler: Yeah; it's a modal editor, which makes me all itchy and annoyed.
14:47 chandler: Maybe some of the code could be salvaged.
14:48 neilv: meow will have some structural editing commands. i polled the users list last year to ask for suggestions of which

15:16 dyoo: the code's on github at: https://github.com/dyoo/divascheme, but since it was written in the DrScheme days, it probably won't work under DrRacket without work

15:33 dyoo: by the way, question re: Racket date/time libraries.  Is it just me, or is it somewhat difficult to make a date object without full knowledge of the structure's contents?
15:33 offby1: *shrug*
15:33 offby1: I seem to always need to pull in some SRFI or other to do what I need to do
15:34 dyoo: that is, I'm staring at: http://docs.racket-lang.org/reference/time.html#(def._((lib._racket/private/base..rkt)._date)) and all those darn fields are required
15:34 dyoo: I have no idea if july 15, 1987 is on a friday or not, for example
15:34 offby1: hmm
15:35 offby1: I don't think you're supposed to make those by hand.
15:35 offby1: for exactly that reason
15:35 bremner: (require omniscience)
15:35 bremner: (provide cryptic-remark)
15:35 offby1: that's probably why I always use SRFI-19

15:38 dyoo: doh.  :)
15:38 chandler: wasn't there someone else with this issue on the user list recently?
15:38 offby1: dunno
15:39 dyoo: I'd like to say something like: (make-time #:month 7 #:day 15 #:year 1987) so that it doesn't do any string parsing.  A Rackety interface, and not a rickety one.
15:39 offby1: yeah
15:39 offby1: I think the structures in srfi/19 are more what you want, if not exactly it.
15:40 offby1: and happily you can convert from those structures to (say) Unix time
