00:24 rapacity: how can I make a require syntax work in (provide (all-from-out ?
00:40 (join) jao
00:48 mithos28: rapacity: did you get your question answered?
00:54 rapacity: nope
00:56 mithos28: what was the question, you are requiring syntax and it does not get provided by an (all-from out …)?
00:59 rapacity: for example when you have (require (planet some-package)) you can do (provide (all-from-out (planet the-package)))

01:00 rapacity: I have a require transformer and I want to be able to do the same thing with it
01:00 rapacity: (require (thing x)) (provide (all-from-out (thing x)))
01:01 mithos28: ah
01:02 mithos28: the spec of all-from-out says only module-paths
01:02 mithos28: so not possible through that
01:02 rapacity: ah, thanks
01:03 mithos28: but I think there is another way if you want to write your own (all-from-out) sort of thing
01:03 rapacity: yeah I'll just use a provide-transformer
01:04 mithos28: expand-import
01:05 mithos28: will get you all of the actual imports from your require spec
01:17 mithos28: does anyone know why srfi/13 does not reprovide string-copy? (asking again in case more people are around tonight)
01:21 (quit) dsp_: Ping timeout: 240 seconds

01:23 (join) dsp_
01:23 eli: But if there's anything useful in `srfi/13' it's usually better to add it to `racket/string' instead.
01:25 mithos28: ok, I was trying to use srfi/13 from TR, realized it wasn't typed and started writing a wrapper and noticed it
01:26 mithos28: racket/string notably is missing string-trim functions
01:27 mithos28: would a patch to re-export the missing bindings from srfi/13 be appreciated?
01:33 eli: mithos28: Maybe.  It's certainly not really something I'd lose sleep over...
01:33 (quit) jeapostrophe: Quit: jeapostrophe
01:34 eli: And re the trim functions -- the left/right variants sound redundant, since they're trivial to do with a regexp-replace,
01:35 eli: the double sided version might be worth it, since writing it with `regexp-replace' can be tricky -- maybe add an ability to "normalize" whitespaces by replacing all one-or-more whitespace sequences by a single space.
01:36 mithos28: I'm not saying that I need it in racket/string, but that is why I am using srfi/13
01:37 mithos28: and just the double ended one, to clean up input from another process
01:37 eli: It would be useful to look up what other languages offer in that dept, and suggest it on the dev list.
01:38 mithos28: ok, I'll do that. And just make the typed/srfi/13 export the full bindings since I am going to write it anyways
01:39 eli: Should also raise the name issue -- `string-trim' sounds too vague, but I don't know what's popular and what's not.
01:39 eli: You were going to write what anyway?
01:39 mithos28: nvm on that,
01:40 mithos28: realized a work around for while the trim thing gets mulled over on dev
01:42 eli: mithos28: BTW, the single `regexp-replace' version that I'm talking about is:
01:43 eli: (define (trim str) (regexp-replace #px"^[[:space:]]*(.*?)[[:space:]]*$" str "\\1"))
01:43 eli: And the tricky thing about it is that people usually are unaware of how useful the non-greedy qualifiers are.
01:44 eli: (So they end up doing a the left-then-right thing.)
01:45 eli: (define (trim str) (cadr (regexp-match #px"^[[:space:]]*(.*?)[[:space:]]*$" str)))
01:45 eli: Probably a little faster.
01:47 mithos28: ok, but thats a lot harder to remember that pulling the library version
01:49 mithos28: http://en.wikipedia.org/wiki/Trim_(programming)
01:50 mithos28: Some languages use trim, others strip, and then obj-C with stringByTrimmingCharactersInSet
01:55 (join) masm
01:57 mithos28: a lot slower than doing it on both sides

02:55 wiley: somewhat noob-ish question: how do I make two expressions behave like one, where the second one is returning a value?
02:56 wiley: the long version is that I have a type-case, and for a certain case I need to do a large check against items in a list and produce an error under certain circumstances
02:56 wiley: and if I don't hit an error, I need to actually perform the operation
02:57 wiley: do I need to find a different way to write it, or can I use the for-each and normal expression I'm currently using somehow?

03:24 Ivoz: hah
03:24 Ivoz: it seems + can serve as an identity function for 1 argument
03:25 mithos28: Ivoz: only numbers
03:25 Ivoz: mithos28: good point
03:25 mithos28: Ivoz: there is also values

14:39 samth: namely, those contexts that do begin-splicing
14:40 samth: but not in general
14:43 jonrafkind: aha my hack is to expand to (define  x 0) so that it won't get printed
14:47 samth: any context that (define ...) works in (begin) should work in too
14:47 jonrafkind: ok let me see..
14:47 samth: and `(define x 0)' changes the semantics of the program
14:48 jonrafkind: shouldn't that x be hidden by hygiene?
14:48 jonrafkind: but ok just using (begin) worked
14:48 samth: what about at module top-level -- it doesn't get hidden in the namespace of things you get from the module
