7:54 hoeck: is it possible to query a clojure fn about the number of arguments it expects?
8:01 ahh, yes it is, thanks to reflection!
14:59 Chouser: I know absolutely nothing about this, so I really am asking -- why is the clojure namespace not org.clojure.lang, etc.?
15:37 rhickey: Chouser: for the same reason that java.lang is not org.java.lang (i.e. no good reason)
15:44 Chouser: heh
15:45 I see this line near the top of PHM.java: new EmptyNode()
15:46 But when I do: (clojure.lang.PersistentHashMap$EmptyNode.) I get No matching ctor found
15:46 what am I missing
16:01 hoeck: Chouser: i guess the inner class EmptyNode is not public
16:02 Chouser: ah, ok. thanks. Shows just how little Java I know, I guess. :-/
16:05 hoeck: i'm used to the openess of clojure too, but i had the "no matching ctor found" exception quite often and now my eyes are trained to recognize the missing `public' :)
16:12 Chouser: seeing something that isn't there is a pretty impressive skill.
16:31 joekarma[lunch]: I see dead people
20:34 Chouser: rhickey: trying to use :exposes is failing for me, and indeed getField returns nil. But getDeclaredField seems to return the desired result.
20:34 This is stock gen-class, testing on javax.swing.DefaultCellEditor's clickCountToStart field.
20:35 (.getField (identity javax.swing.DefaultCellEditor) "clickCountToStart")
20:51 from the Java docs it looks like getField only finds public fields, not protected ones like :exposes is looking for.
21:02 rhickey: Chouser: ok, do you have a fix you want me to add?
21:02 Chouser: I think so, but my test cases are pretty thin.
21:03 I'll post what I've got later tonight, tests and all.
21:03 rhickey: isa-based multimethods and a la carte hierarchies are up!
21:04 Chouser: nice.
21:04 you have the 15 pages of docs and examples up too, right? ;-)
21:04 docs are such a drag.
21:05 rhickey: all the functions are doc'ed, writing up a message to the group now
21:05 also added resolving keywords - ::foo reads as :current-ns/foo
21:06 Chouser: interesting.
21:08 rhickey: keywords make better tags, since they print/read as themselves, but ` doesn't add namespaces to keywords that don't have them
21:08 but namespaces are important (required in fact) for tag hierarchies
21:09 Chouser: I used :xml-filter/something-or-other and felt odd about it. this'll be nice.
21:20 Actually, I probably should merge these two changes. If you want to replace line 415 of genclass.clj, it will fix my one test case:
21:20 I probably should *not* merge these two changes.
21:20 (let [fld (.getDeclaredField super (str f))
21:24 rhickey: Chouser: line 413?
21:25 Chouser: oh, probably. sorry, I've other changes in that file. just replace .getField with .getDeclaredField.
21:26 rhickey: ok, it's up
21:27 Chouser: fantastic -- works for me, now.
21:36 ok, I just posted my tiny gen-class patch and test. biab.
