10:41 samth: (2) a hashtable mapping names like "fun1" to values like the fun1 function

15:48 Demosthenes: 23.1.1
15:49 Demosthenes: jao: i'm fairly recent... i tend to keep up with org-mode
15:50 jao: Demosthenes: and what does C-h f completion-at-point say?
15:51 Demosthenes: oh crud, i'm reading the release notes on 23.2, and completion-at-point is a new emacs provided command
15:51 Demosthenes: http://www.gnu.org/software/emacs/NEWS.23.2
15:51 jao: Demosthenes: oh, i'll have to update the docs then
15:51 Demosthenes: urg, and i just finished hashing out org, ya-snippet, and autocomplete to keep them playing nice with tab
15:52 Demosthenes: speaking of, OMG autocomplete in the repl ROCKS
15:52 jao: it's also available in racket buffers :)
15:52 Demosthenes: i mean auto-complete-mode
15:53 jao: ah, *auto*complete, sorry
15:53 Demosthenes: not geiser specific
15:53 Demosthenes: yeah, m-tab would be cool in a racket buff ;]
15:53 jao: you mean in drracket?
15:53 Demosthenes: uh, i only use emacs
15:53 Demosthenes: this is my second day in scheme
15:54 jao: then m-tab *is* available in racket buffers (but you'll need 23.2, i'm afraid)
15:54 Demosthenes: i read in the directions that m-tab was the geiser compelte key
15:54 Demosthenes: exactly
15:55 jao: Demosthenes: or perhaps you could define an alias to the old name
15:55 (quit) Gwyth: Ping timeout: 245 seconds
15:57 Demosthenes: atm i'm running what ubuntu provides for 10.10
15:57 Demosthenes: i'd rather not manually install emacs for now. if completion is the only thing that impacts, its ok

16:08 jao: Demosthenes: does "(defalias 'completion-at-point 'complete-symbol)" fix your problem?
16:14 Demosthenes: then it says i have no tags tables loaded
16:15 jao: in a geiser repl?
16:16 Demosthenes: yep
16:16 Demosthenes: Starting Geiser REPL for racket ...
16:16 Demosthenes: Racket REPL up and running!
16:16 Demosthenes: if: Wrong number of arguments: #[(arg) "ƒ
16:16 Demosthenes: [arg info-complete-symbol fboundp complete-tag error "%s" substitute-command-keys "No tags table loaded; use \\[visit-tags-table] to load one"] 4 1945487 "P"], 0
16:17 Demosthenes: yeah, tehre were some bytestrings there... anyway, its not required
16:17 Demosthenes: i've got the ref manual up in one window, and the repl in the other. auto-complete is allowing reuse in the buffer, so its good
16:19 jao: okay (real geiser completion is better, imho (it completes on identifiers visible in the current namespace, asking the racket process for that))
16:19 Demosthenes: i'm sure it's superior, the issue preventing me from using it is on my side. i'll deal until i upgraed emacs ;]
16:20 Demosthenes: i appreciate you writing it!
16:20 jao: np!

16:22 Demosthenes: *ponder* lets see, i'm adjusting to the diffs between CL and racket (i should have just learned racket first), loving the regexp library, text scraping and normalizing to populate sqlite, learning scheme->sqllite integration, etc.

17:30 samth: rmitt, first, there's no 'interpreter' in Racket on any significant platform, it's all jit-compiled
17:30 samth: second, that would probably be more efficient; send in a patch!

17:33 rmitt: samth: Thanks.  I thought perhaps it was decided that the let would cost about as much as two calls to car.  Also, I know next to nothing about jit, but was under the impression that some VMs (e.g., JVM?) could optimize away the common expression.

22:59 rapacity: how do I iterate over the keys/values of a hash using for: in typed/racket ?
23:08 Demosthenes: jao: i noticed geiser on having bad input to the repl, alt-p brings up the last correct statement. makes editing difficult when you typo
23:12 jao: Demosthenes: if by 'bad input' you mean an incomplete sexp, that's difficult to fix. Geiser only sends (and saves) stuff to racket in sexp units.
23:12 Demosthenes: *ponder*
23:13 Demosthenes: yeah, slime kept every input in the history
23:13 Demosthenes: i was really thrown when i keyed something wrong, and hit alt-p to pull it up to fix the error and it wasn't there... i had to scroll the buffger back and mounse-2 that text so it'd be pasted as input
23:13 Demosthenes: haha, on an unrelated note, i just discovered scheme has no NIL ;]
23:14 Demosthenes: *laugh*
23:21 eli: Demosthenes: That's a very nice feature.
23:22 eli: Having a NIL that is a boolean, a list, and a symbol in CL is one giant wart.

23:23 (quit) masm: Quit: Leaving.
23:24 chandler: Alas, Scheme didn't completely remove that wart.
23:25 eli: You mean the #f/anything-else?
23:25 chandler: (if '() 1 2) doesn't make sense regardless of whether it evaluates to 1 or 2.
23:25 chandler: Yeah.
23:26 eli: Yeah, but that's a *much* smaller wart to my taste.
23:26 chandler: I try not to taste warts.
23:26 eli: Especially given the sticky issue of `and' etc wrt tail calls which is a good point in favor of this behavior.
23:27 chandler: Not sure I understand the issue.
23:29 eli: (and E1 E2) should evaluate E2 in a tail context, which means that `and' cannot enforce proper booleans.  You can do that enforcing elsewhere (like in `cond' and `if' tests), but that makes things a little more confusing in yet another wartish way.
23:38 Demosthenes: yeah ;]
23:39 Demosthenes: always idiosyncrasies
23:39 Demosthenes: *shrug*
