08:40 moritz_ good morning
08:40 moritz_ (my thesis is about spin transport phaenomena in mesoscopic systems. Weird stuff.)
08:40 azawawi works with p6? ;-)
08:41 moritz_ no
08:41 azawawi so parrot will be production quality by 2010
08:42 azawawi moritz_: where can i find the rakudo spec passed/failed graph?
08:42 moritz_ http://rakudo.de/

15:44 masak Rakudo++
15:47 moritz_ rakudo++ indeed
15:49 masak moritz_: if I see a file in t/spec with underscores, should I change its name to something with dashes? or are there good reasons not to?
15:50 moritz_ masak: if you do it, please do it for all at once, and adapt spectest.dat
15:51 masak moritz_: that's a nice idea.
15:51 masak I might do it later today, no promises. :)

16:16 p6eval ..Perl...
16:16 TimToady currently STD only reports the leading 0 if there was some other difficulty, but maybe it should do it all the time
16:17 rindolf Someone I know from fc-solve-discuss created an Assembler where a leading 0 indicates Hexadecimal.
16:17 moritz_ rindolf: even more fun ;)
16:17 TimToady I blame the hindu-arabics :)
16:19 masak meanwhile, in the rest of the world, a leading 0 indicates nothing in particular.
16:21 rindolf What will a leading 0 signify in p6?
16:21 TimToady nothing in particular
16:21 moritz_ rindolf: a warning
16:21 rindolf And octal will be 0o?
16:21 TimToady or :8<...>
16:21 moritz_ or .oO ;)
16:21 rindolf I see.
16:22 TimToady .oO(mental arithmatic goes here)
16:22 TimToady *arithmetic even
16:22 kisu__ joined #perl6
16:23 stephens joined #perl6
16:23 masak o_O
16:23 PerlJam Is being arithmatic like being arthritic in any way?
16:24 moritz_ arithmatic = arithmetic with arthritic brain?
16:24 TimToady no, it's automatic arithmetic
16:25 TimToady you're thinking of arithitis
16:26 masak I think we have an arithmatic down in the lunch room.
16:26 moritz_ TimToady: yes. English can be so confusing from time to time ;)
16:26 meteorjay joined #perl6
16:26 TimToady and Chinese isn't even one language
16:27 TimToady all(@Chinese) == False
16:28 TimToady well, I wonder if I should do anything today...
16:29 rindolf TimToady: contribute to en.wiktionary.org
16:29 TimToady I meant, should I be doing something I should already be doing?  :)
16:30 TimToady I don't need new things in that category...
16:30 rakudo_svn r32941 | coke++ | Resolve RT#60592 ; rename :lexid to :subid
16:30 rakudo_svn r32941 | coke++ |
16:30 rakudo_svn r32941 | coke++ | change docs, PIR syntax, and internal C structure that housed the data.
16:32 PerlJam TimToady: release a perl 6 compiler that's "official"  ;-)
16:32 masak PerlJam: what do you think we've been doing all this time?
16:32 PerlJam masak: yeah, but he should do it *today*  :)
16:33 perl6 please, release me!
16:33 masak ...just to up the stakes a bit, eh?
16:34 masak someone should make a webcomic about poor little perl6 being held prisoner underground by the Perl community, for fear of what it might do if let out.
16:34 moritz_ masak: nice idea ;)
16:34 [particle] sounds a bit like serenity
16:34 PerlJam I like how "git diff master..lex4" shows me trailing whitespace in red.
16:35 masak [particle]: I haven't got to that series yet. I hear it's good though.
16:35 [particle] pj: my .vimrc shows me trailing ws in red
16:35 [particle] masak: hulu.com has them all
16:35 masak moritz_: the phrase 'please, release me' would figure in every installment.
16:35 masak [particle]: noted.
16:36 PerlJam [particle]: for all files or just certain ones?
16:37 masak [particle]: "We're sorry, currently our video library can only be streamed within the United States."
16:37 [particle] pj: all files. i hate all trailing ws equally, but it could be configured per-filetype i suppose
16:37 PerlJam This is the first time I've noticed trailing whitespace of any kind (since usually it's invisible :)
16:37 [particle] masak :(
16:37 masak indeed.
16:37 [particle] PerlJam: pugs repo is full of it, unfortunately
16:38 PerlJam does it really bother you that much?
16:38 PerlJam I'm still in the position of wonder why anyone even cares.
16:38 PerlJam s/wonder/wondering/
16:41 TimToady .oO(if purl were here, I'm sure she'd have some opinions about the merits/demerits of cage cleaning)
16:42 * masak is glad purl isn't here
16:45 [particle] perljam: it messes with my ability to edit files quickly. if i go to the end of the line, my cursor isn't over the semicolon, it's to the right of it by some number of invisible characters
16:46 smg joined #perl6
16:46 [particle] so, i have a ',ts' vim macro that removes all trailing space in a file

22:01 masak I know what's going on in the following piece of code, but I would like for someone to tell me whether this shloud work:
22:01 masak rakudo: my $cl = { "$^name upcased becomes {$^name.uc}" }; say $cl("larry")
22:01 p6eval rakudo 32961: OUTPUT[too few arguments passed (0) - 1 params expected␤current instr.: '_block26' pc 191 (EVAL_12:69)␤]
22:02 masak s/shloud/should/
22:03 moritz_ why shouldn't it work?
22:03 masak moritz_: because the thing inside the string is also a closure.
22:03 moritz_ rakudo: my $cl = { $^a ~ $^a }; say $cl("b")
22:03 p6eval rakudo 32961: OUTPUT[bb␤]
22:03 moritz_ rakudo: my $cl = { $^a ~ { $^a }.() }; say $cl("b")
22:03 p6eval rakudo 32961: OUTPUT[too few arguments passed (0) - 1 params expected␤current instr.: '_block23' pc 167 (EVAL_14:65)␤]
22:03 masak moritz_: then you agree that it's a bit odd that it doesn't work?
22:04 moritz_ ah, I see what you mean.
22:04 masak should it or shouldn't it work?
22:04 moritz_ but since you can't pass arguments to closures in strings, it makes most sense to use the outer closure's self-declared parameters
22:04 masak I mean, there's no way to send arguments to a closure in a string anyway...
22:04 masak right.
22:04 * masak files rakudobug
22:05 moritz_ I don't know if it's specced, from a dwim'miness POV it should work.
22:05 masak aye
22:05 jnthn masak: I think that's for the language list rather than rakudobug, IMO.
22:05 masak jnthn: gotcha.
22:05 masak (I already made the wrong call once today with sign())
22:06 jnthn I could also argue that keeping closure parameter semantics consistent is desirable, and saying that if you want a closrue that takes paratmers you can always do a pointy instead.
22:06 jnthn erm
22:06 jnthn Not closure paratmers, placeholder parameters.
22:06 jnthn But yes, I see the other argument too.
22:07 masak each time you say something worthwhile, I have to redo my text selection in the IRC buffer :P
22:08 * moritz_ experienced the same thing a few times today already
22:08 jnthn masak: That's OK, many of the times you say something worthwhile I have another Rakudo ticket to work on. ;-)
22:08 masak so $^they are called 'placeholder parameters'?
22:08 moritz_ ;-)
22:08 jnthn I believe so.
22:09 masak jnthn: good thing I don't say something worthwhile that often, then :P
22:09 masak either I've been losing speed lately, or rakudo's been getting more robust, or both.
22:10 jnthn The proportion of the Perl 6 RT tickets you're the creator of suggests otherwise... ;-)
22:10 jnthn I'd like to hope Rakudo is getting more robust.
22:10 jnthn There can only be so many bugs, surely? :-)
22:11 * moritz_ notices that real world hacking tends to catch very different bugs than the test suite
22:12 jnthn Yeah. I do try these days to put something close to what the bug was into the test suite, or un-fudge a test that fixing that made pass.
22:12 jnthn The second does happen a bit too.
22:17 masak mail sent.
22:20 masak now for the other bug I found...
22:20 * masak grins evilly

23:10 lambdabot Title: gist: 27262 — GitHub
23:11 masak I didn't work too hard trying to shrink the example further.
23:11 pmichaud yet another lexicals bug.
23:11 lambdabot pmichaud: You have 5 new messages. '/msg lambdabot @messages' to read them.
23:11 masak pmichaud: aye, I knew you were going to say that :)
23:11 pmichaud well, that's what it _is_  :-)
23:11 masak well, sure.
23:12 masak pmichaud: do you think it will sort itself out after the lex branches come merging back to trunk?
23:12 pmichaud yes.
23:12 masak good.
23:12 pmichaud so far every lexical example that's been submitted seems to work in the lex branch
23:12 masak very good.
23:13 pmichaud right now we're just having trouble with context management (contexts being collected too soon or not at all)
23:13 masak sounds tricky.
23:13 jnthn Having seen, but not worked on, the code in question I can say it almost certainly *is* tricky.
23:14 pmichaud we're really close.
23:15 masak pmichaud: as in, if I go to bed now I might have to backlog the merge?
23:18 pmichaud you might.
23:19 masak left #perl6
23:42 * moritz_ risks missing the merge, and goes to bed now ;)
