13:23 drewr: I love that lisps handle rational numbers correctly, but is this the only option when you want a float?
13:23 user> (/ 3 2)
13:23 user> (* (/ 3 2) 1.0)
13:24 Chouser: (float (/ 3 2))
13:24 drewr: Chouser: You'd think searching the api page I would have found that. :-)
13:24 Chouser: :-)
13:26 I don't know if there's a way to from float to ratio, though.
13:26 drewr: Does it bother anyone else that the docstring comes before the parameters in a function def?
13:27 Chouser: there can be multiple parameter sets.
13:27 In which case any other placement of the docsstring get a bit awkward.
13:28 drewr: OK, multiple arity.
13:28 Chouser: yessir
13:28 drewr: Well, I guess it's a good tradeoff then.
13:30 Chouser: I think that's the rationale, anyway.
13:30 drewr: That's reverse of every Python, elisp, CL, probably others. Trying to get used to it.
13:31 Chouser: well, it's a odd syntax for multiple arity too, but I find I like the convenience.
13:31 drewr: From the code I've read so far, I agree.
13:31 Chouser: It's quite nice for setting up default params.
14:42 (/ (long (* 1.5 1000)) 1000)
15:10 drewr: Chouser: Nice :-)
15:11 rhickey: drewr: what's nice?
15:11 Chouser: (/ (long (* 1.5 1000)) 1000)
15:11 for converting a float to a ratio
15:11 I think he was being fascetious.
15:11 drewr: ;-)
15:13 rhickey: hmm... yes, CL's rationalize
15:14 Chouser: BTW, I'm enjoying the reader syntax discussion in the group, independant of any final decision.
15:15 rhickey: :)
15:16 * drewr too
15:16 Chouser: And I also wish (oh how I wish) to be using Clojure for work instead of C++.
15:17 rhickey: use it to generate C++
15:17 Chouser: heh.
15:18 abrooks: Which thread is the reader thread? ("Syntactic extensibility"?)
15:18 Chouser: abrooks: yes
15:18 I'm reading about composable monkey patching instead of writing C++ code.
15:18 rhickey: will be out in novel form soon
15:18 abrooks: Heh.
15:19 drewr: That explanation of generic functions was the most concise and helpful I've seen.
15:19 rhickey: great!
15:23 Chouser: Is there a way to dispatch multimethods on params other than the first?
15:24 rhickey: sure, the dispatch fn is an arbitrary fn of _all_ of the arguments
15:25 you can use any subset of the arguments, their types, values, attributes, look up in a db, etc
15:25 Chouser: ok, so my confusion may be because all the examples I've seen have methoeds with arity 1
15:26 rhickey: not this one: http://
15:26 Chouser: ah, ok, that helps. thanks.
15:53 rhickey: user=> (rationalize 1.5)
15:53 user=> (rationalize 1.2345)
16:14 Chouser: :-) thanks.
16:14 the name is from CL? We could have floatize, too.
16:15 rhickey: yes, from CL - you have float already
16:15 abrooks: Chouser: That would be floatnlize. :)
16:16 rhickey: but it's not the same, i.e. not ratio
16:16 (rationalize 1) -> 1
16:16 Chouser: ah, ok.
16:17 (floatnlize 1) -> 1
16:17 rhickey: I don't think so
17:39 MarkJP: hmmm
17:39 user=> (= (.. (new Object) (getClass) (getDeclaredMethod "finalize" nil) (getReturnType)) (class Void))
17:39 shouldn't that be true?
17:42 abrooks: Don't you want t wrap (class ....) around the first contained form?
17:42 Or is that your point.. that you shouldn't have to?
17:42 MarkJP: didn't think I had to
17:42 let me try
17:42 that works
17:42 abrooks: Right.
17:43 MarkJP: should I have to?
17:43 doesnt getReturnType return a class
17:43 Chouser: I don't think that's what you mean.
17:43 (class Void) -> class java.lang.Class
17:44 MarkJP: ohhh
17:44 Chouser: so you want just Void not (class Void).
17:44 MarkJP: that doesnt work either
17:44 Chouser: right
17:44 abrooks: I think the comparison still doesn't... work.
17:44 MarkJP: user=> (= (.. (new Object) (getClass) (getDeclaredMethod "finalize" nil) (getReturnType)) Void)
17:45 * abrooks is a little slow.
17:45 abrooks: Need more tea.
17:45 Chouser: getReturnType is returning just void. I'm not sure how that's different from Void.
17:47 MarkJP: got it:
17:47 (= (.. (new Object) (getClass) (getDeclaredMethod "finalize" nil) (getReturnType)) (. Void TYPE))
17:47 Chouser: nice
17:47 MarkJP: thx for setting me straight
17:47 Chouser: What are you working on?
17:48 MarkJP: turning a clojure proxied class into java code :p
17:48 need to know when I have to use the keyword "return"
23:46 Chouser: Shouldn't this work? (binding [x 5] x)
23:47 I must be up too late. It seems like that should just return 5 instead of: java.lang.Exception: Unable to resolve var: x in this context
