pmichaud FROGGS, jnthn: I agree with jnthn++ . The handling of dynamically quantified expressions has always been meant to be handled outside of the standard quantifier node type. 00:58
especially since the thing that follows ** is to be a closure. 00:59
if it's possible to cleanly make the range dynamic via the existing rxtype node, I'll be okay with that, but more likely it wants a specialized node type. 01:01
the other reason for making it a specialized node type is to more cleanly distinguish declarative versus procedural quantifiers. 01:02
the other other reason for making it a specialized node type is so that one can smart-match the number of repetitions against the value returned from the closure. Although p6 only allows Int and Range to be returned from a closure now, at one time it was allowed to be lists, and we might want that capability again someday (e.g., \d ** { @primes } ) 01:05

sorear not reliably
timotimo okay, how about "sort-of-kind-of"? how would i do that? in rakudo?
sorear select and FIONREAD provide advisory notification of data, but you're supposed to set file descriptors to nonblocking in case of false alarm
timotimo can i even do that to $*IN etcetc? 01:48

01:59 hypolin left 02:01 btyler left, hypolin joined
[Coke] the rakudo failures on feather in S02-bool.t are a result of the iospec merge. 02:16
er, S02-types/bool.t
labster Yeah, we know. 02:17
[Coke] ... ok. if someone already did a bisect, putting that on the ticket would have saved me several hours. 02:18
labster But what FROGGS and I are trying to figure out is why these two lines in canonpath cause the failure: gist.github.com/FROGGS/0d1a9f4967a2c4d49606
dalek rl6-bench: 8dad53a | (Geoffrey Broadwell)++ | bench:
Several miscellaneous bugfixes in bench
 02:19
[Coke] thanks for trying to track it down. 02:20
rt.perl.org/rt3/Ticket/Display.html?id=117957 if you figure it out.
labster Sorry, I fell asleep last night while we were talking about it. 02:22
[Coke] heh. I fell asleep in the middle of my bisect and just got back from a trip across 3 states to finish it up. ;) 02:29
02:34 kingbeast left 02:36 s1n left
pmichaud which two lines in canonpath ? 02:40
labster They're two regex substitutions, triggered when $*TMPDIR is created. They're the two lines he's commented out in the gist above, 9 and 12 02:42
pmichaud I'm not sure those lines are the actual cause of the failure. 02:44
maybe I should read prior backlog on the topic, though.
labster You should ask FROGGS, as he was the one doing the bisect. 02:45
labster still doesn't have a feather account.
pmichaud reads backlog 02:46
labster start here: irclog.perlgeek.de/perl6/2013-05-26#i_7116874
pmichaud this bug feels like a GC or pointer problem of some sort, and commenting out those lines changes things just enough to cause the bug to appear somewhere else. 02:48
(or disappear) 02:49
i.e., a heisenbug
02:49 btyler joined
pmichaud however, just looking at the code.... 02:52
$path ~~ s:g { '/'+ } = '/'; # xx////xx -> xx/xx
seems horribly inefficient.
timotimo i made an amazing console program that will, given a time in minutes, fill up one line of the terminal using eigths of blocks from the unicode "block elements" chart 02:58

timotimo apparently i can only get the terminal width via %*ENV on gnome-terminal, which b0rks if i have only one line :( 03:14
03:17 s1n joined 03:29 fgomez joined
labster oh, that is inefficient. It's a port of File::Spec, so blame perl 5 :o) 03:33
maybe the problem will disappear on the JVM ... and I just use System.getProperty("io.tmpdir") instead 03:36
timotimo: just put a 1; at the end of your modules 03:37
timotimo labster: huh?
dalek kudo/nom: 25a0b3f | pmichaud++ | src/core/IO/Spec/Unix.pm:
Make IO::Spec::Unix.canonpath more efficient.
 03:38
labster it sounds like a oneliner program is not working, so add a "1;" on it like perl 5 modules (as a joke)?
timotimo oh, that's funny 03:39
sorry, i don't know any perl5
labster Yeah, that was a misfeature of Perl 5, where a module had to return true to load correctly, so everyone puts a 1; at the bottom of the file. 03:40

colomon [Coke]: I'm not testing anything to do with roast, just testing how the modules work. 04:54
[Coke]: might be able to extend it to roast, I dunno. Same sort of idea, but not identical. 04:55
pmichaud timotimo: I suspect it's NYI in Rakudo, but S11 says that "use Term::ANSIColor :EXPORT;" will both import Term::ANSIColor and export its symbols 05:10
perlcabal.org/syn/S11.html#Compile-...mportation
timotimo cool, thanks 05:11
yeah, Error while importing from 'Term::ANSIColor': no such tag 'EXPORT'

tadzik 1b?
oh!
FROGGS_ :o) 10:34
tadzik awesome, FROGGS_!
FROGGS_ it just can do $ and @ though, and I need to stash that prototype somewhere...
and I believe it wont work if the sub is declared after the sub-call is parsed :/ 10:35
tadzik Isn't that the same as in Perl 5?
iirc in p5 you can't omit () in subcall if the sub is not declared yet 10:36
FROGGS_ perl 5 says that the prototype must be known at compile time
tadzik ah
FROGGS_ so I guess it will work if you declare that sub right after its call within the file
$ perl -E 'use v5; say test "a", "b"; sub test { scalar @_ };' # nothing 10:38
$ perl -E 'use v5; sub test { scalar @_ }; say test "a", "b"' # 2
huh
cool

I see
FROGGS_ same with a $$ prototype
tadzik I'd be surprised :)
10:39 konnjuta joined
FROGGS_ so I don't have to worry about that 10:39
tadzik indeed 10:40
FROGGS_ but it can't be the other way, since the knowledge of the prototype changes the parsing
and even p5 doesnt parse again when it hits a prototype to a previously used sub 10:41

that goes against the idea of "private" :-)
dagurval who is supposed to set private attributes, if not the constructor? o_O 20:00
that makes no sense to me, coming from C++

submethod BUILD() { $!foo = "bar" }
But you could have written has $!foo = 'bar'; in that case.
moritz I also don't understand why folks write private attributes, and then want to give the user of the object direct write access to that attribute (but not read access; it's private after all) 20:03
