4:43:29 v3ga White_Flame: gotcha, thanks. =P

5:39:10 sukaeto v3ga: ningle has pretty good FastCGI support

5:41:21 sukaeto I've used it (via caveman) in production, with a few FastCGI instances sitting behind nginx

9:03:30 pve Hi! In a call to a function, such as (make-foo :a 1 :b 2), is it correct to call the ":a 1 :b 2" part (including the keywords) the "arguments"?

9:03:45 pve and "1" and "2" the "parameters"?

9:04:00 pve sorry if this is too elementary

9:11:28 phoe these are commonly called keyword parameters

9:12:49 phoe the CLHS also calls them that way

9:13:06 phoe as in, everything after &key is keyword parameters, except for any &allow-other-keys

9:13:17 beach phoe: But these are the argument.

9:13:24 beach Not the parameters.

9:13:32 beach It's a call, not a definition.

9:14:30 phoe oh! sorry

9:14:45 phoe ACTION re-reads 3.4.1.4

9:16:42 beach pve: I think "keyword arguments" is fine. If you want to be more specific, you could say "keyword-argument pairs".

9:17:09 beach pve: Notice, however, that you can't tell from a call whether they are keyword arguments.

9:17:37 beach pve: For example: (list :a 1 :b 2) is a fine call, but they are not keyword arguments.

9:18:18 pve beach: great, thanks

9:18:23 pve phoe: ^

9:18:23 beach pve: Conversely, in something like (bla 'a 1 'b 2) they can very well be keyword arguments.

9:19:50 pve beach: in (list :a 1 :b 2) they're just "arguments"?

9:20:08 beach Yeah.

9:20:15 pve ok, thank you

9:20:54 beach Also try (defun f (x &key ((a y))) (list x y)) then (f 234 'a 33)

9:21:34 pve ACTION tries

9:22:00 no-defun-allowed One too many parens around (a y)?

9:22:29 beach I don't think so. Did I do it wrong?

9:22:40 no-defun-allowed Well, that works -- I haven't seen that before.

9:22:45 beach (a y) would be the variable a with a default value of y.

9:22:54 no-defun-allowed Indeed.

9:23:10 beach This means the variable y to be recognized by the keyword a.

9:23:56 beach The glossary entry for "parameter" distinguishes between "parameter" and "argument".

9:25:08 pve beach: hmm, I think I need to read the spec for that one.. my first reaction was also, "looks like one pair of parens too many"

9:27:45 pve beach: ok, I think I understand now

9:29:37 pve it's a way to have a keyword parameter that is not given with a keyword symbol

9:30:37 scymtym it could still be a keyword but not the default one derived from the variable name

9:30:49 pve right

9:32:01 beach no-defun-allowed: You haven't seen it because you haven't attempted to implement lambda-list parsing. :)

9:32:04 pve and reading the above again, beach did say it, but I just couldn't parse it

9:32:05 scymtym which is probably the more common use-case because it let's you chose the keyword parameter name in a way that maintains the "external interface" but bind the passed argument to an unrelatedly named variable

9:32:42 no-defun-allowed beach: That is quite possible :)

9:46:23 _death one use for it is to bind to a special variable without an explicit let

9:48:43 _death another is for CL names that can't be bound

10:06:20 radiohead_fan has anybody ever worked with cl-tcod?

10:12:37 Xach radiohead_fan: i have worked to get it to build on my system, but never actually used it

10:19:23 radiohead_fan damn.... i need help with using it

11:04:18 no-defun-allowed radiohead_fan: Do you really like True Stories that much? I thought it was generally considered to be Talking Heads' worst album.

11:04:18 no-defun-allowed Joking aside, what's it do? It looks like you use it to make roguelike games.

11:04:50 radiohead_fan yeah its for roguelikes

11:05:05 radiohead_fan wanted to make a very small roguelike for this halloween

11:05:28 no-defun-allowed I see.

11:11:29 radiohead_fan everything was going fine but when i was coding the part of the key input i found no way of making a key exit and close the window, ive even tried other methods (from various tutorials) and they just dont seem to work
