avar parrot be sloww:)
and very incomplete 00:31
[particle] *extremely* incomplete
it can do 2 + 2

putter Hmm. Looks like src/perl6/Perl-6.0.0-STD.pm doesn't have regex aliases yet. fudging... 01:28
TimToady regex aliases? 01:37
I'm just about to check in a major overhaul on symbol processing that uses less magic 01:38
you mean the {*} #= thingies? 01:41
svnbot6 r15315 | lwall++ | symbol processing now uses normal capture. 01:44
r15315 | lwall++ | endsyms are done with context sigs on the proto tokens.
r15315 | lwall++ | the only magic is now that proto sig contexts are expected to propagate
r15315 | lwall++ | context var declarations even if the multi adds a (--> Foo) sig.
01:46 UWC joined
TimToady putter: or do you mean naming a [...] and calling back to it? 01:51
putter mumble := construct where mumble is a named/numbered scalar, array, or hash alias, or an external scalar, array, or hash alias. ;) 01:55
$3 := (foo)
TimToady oh, yeah, it's missing... 01:57
hmm
putter arg. the parrot rx_ tests repeatedly use a target string. which starts with \n and continues through $% on to 0123 etc. so the question is, what can you do toi this string so that \n is expanded but $% isn't. ($% expands as "0", so guess where the first <alnum> hit is :). weeeeee. 01:59
ah, well. special casing coming up. 02:00
re alias, I used a modified version of misc/Grammars/rx_grammar.pm's. 02:01
TimToady took a whack at adding it. 02:10
svnbot6 r15316 | lwall++ | Added regex binding

putter Anyone around who understands the p6 "logical newline" concept? 03:06
avar in say and such? 03:07
03:09 justatheory joined
svnbot6 r15317 | lwall++ | fixed syntax error, added more #= to regex 03:09
avar TimToady: Do you recall when in perl history you brought in Henry Spencer's regexp code? It's for an evolving joke in re::engine::POSIX docs 03:11
avar snickers
putter it initially seems like p5's /\n/ has a different concept of what \x0a and \x0d patterns should be matched than p6 does
avar # $1 works too, but one should never half-ass nostalgia 03:12
s/\(.*\)/string: \1/g;
:)
putter (or so I'm currently interpreting some rx_ test failures)
TimToady I believe that was version 2 03:13
but the switch from \(...\) to (...) was version 1 03:14
putter: \n is intentionally different in p6
\n is "newline character" in Perl 5. 03:15
in P6 it's "logical newline", even if that's more than one character
putter or even if it's just \r?
TimToady or a newline character from another culture
putter k 03:16
TimToady \x0D was newline on old macs
maybe new macs too
03:16 silug joined
TimToady so a bare \r is interpreted as a newline as well. 03:17
putter very very (blow of the dust decades old) fuzzy recollection is that one can't unambiguously count "platform independent newlines". no idea what the screw case was. i could easily be wrong. 03:18
TimToady in p5 \n was just \x0A on most machines but \x0D on macs
allbery_b windows ises 0x0d 0x0A as newline, but you sometimes get unixy files or even files which mix them 03:19
and then there's the question of what to do with 0x0A 0x0D..
putter just needs a regex for p6 n and N ... sigh 03:20
TimToady \N is just [<!before \n>.] 03:21
putter :) 03:22
TimToady \n to the first approx is \r\n?|\n\r?|\x2028|\x2029 03:23
probably reverse the first two to put the common case first 03:24
putter someone has a LF-CR convention? if not, is it worth risking off-by-one out of sync problems. 03:26
avar putter: working or P::C::R? 03:27
putter misc/pX/Common/yet_another_regex_engine 03:28
ach, but I'm really all set for now. knock off a few more tests and call it a night. 03:29
current design principle is "don't do it right, just pass the tests". Did I mention we really really need more regex tests? Maybe we can scavange some from all the perl compatible regex libraries out there. Or write a generator. Or... 03:30
TimToady except, of course, they'd do \n wrong from our perspective... 03:31
dinner & 03:33
putter cheers
(easiest bug fix is removing a broken test:)
tene argh 03:55
it really bugs me when people say "astericks" instead of "asterisk"
wow. mischan.
tene fails.
revdiablo Haha 03:56
I was about to chime in agreement
03:58 mr_ank joined
putter getting there. but the next bit (overhauling captures to be spec) will be painful (because the engine itself is using the current, non-spec, capture behavior). ah well. 03:59
svnbot6 r15318 | putter++ | misc/pX/Common/yet_another_regex_engine - some progress. p6 rx_ tests currently 75% ok, 11 sec.
putter and whitespace handling is a complete kludge. and no ratchet. and... enough unto the day. ;) 04:00
good night & 04:04

eric256 is there an easy way to access the last value of a for loop? without doing state $last; and then $last = $_ at the bottum of the loop. i remember a discusion about that before but i'll be darned if i remember how to do it 18:48
diotalevi If your for loop is really just a search then first{} will get you there directly. 18:52
er, wait. I thought this was #cbstream. dang.
gaal eric256: I think the solution was to write the loop with while rather than for... 19:01
19:03 mr_ank joined
eric256 hmm i'm not sure that a while buys me much more that for with the states, but i'll give it a shot 19:03

eric256 is pugs.kwiki.org/?ConvertingPerl5ToPerl6 dead? 19:07
wolverian hm, scala's Iterable trait has an .exists method that is basically any(). I find the naming quite convenient, so there's e.g. Set.exists. </random observation> 19:11

[particle] has 10 unexpectedly succeeding tests 19:33
9 in t/pmc/mmd.t
1 in t/pmc/threads.t
moritz I'll have to update and smoke again ;) 19:39
[particle] thinks his unexpected successes are due to having built languages/perl5
jisom what would be the right regex/rule/whatever to match any byte over 0x80? 19:40
[particle] something that works in perl 6 as specced, or today on parrot?
jisom parrot
to see is something's text or binary, I'm using <cntrl-[\t\r\n ]+[\x80..\xff]> 19:41
until parrot get's something better
[particle] checking... 19:44
you can do a pir closure
eric256 are there sets ? like can i have a set of 1-9 and then remove other sets from it? /me is thinking of a soduko solver ;) 19:45
jisom I'm just trying to figure out if a line is binary or ascii with an error prone heuristic 19:46
[particle] isn't there a printable? 19:47
so, you want to match non-ascii, basically
actually, non latin-1 (>255)
jisom print fails on tabs I believe.... 19:48
[particle] your overall goal is to determine whether a file is binary or text, correct? 19:49
jisom yes
[particle] eric256: there is a sudoku solver already, i think
coke and leo may know more
jisom in parrot, examples/pir/sudoku.pir :)
[particle] but you can use an array or a string to do that set
19:52 theorbtwo joined 19:53 UWC joined
svnbot6 r15319 | lwall++ | Some precedence cleanup, some sublanguage reworking. 19:53
eric256 particle yes, but that doesn't mean it can't be doe agian ;) besides the one there is labeled specificaly as not working
it was the removing elements from sets etc that i was interested in, i can program them, but if we had set and set operators built in then that would be better to use ;) 19:54
[particle] eric256: we have arrays, which you can use 19:55
or stringss
eric256 yes particle i read that the first time you said it. it isn't a SET but it can be used as one, there was talk before about adding actual real sets to the language which would have set operators associated with them..hence why i asked here to see if someone knew what became of that, 19:56
i found some stuff in the docs but they appear to refer to useing <<+>> and >>+<< on sets, but those are now hyperops...hard to track stuff and how it changes sometimes
[particle] that's perl 6, not parrot 19:57
if you're looking for perl 6 syntax, go to #perl6 on freenode
and yes, perl 6 has sets
jisom isn't this?
moritz [particle]: this _is_ #perl6
[particle] aw, crap
sorry! 19:58
jisom wants to know how to get '<cntrl-[trn]> | <[x80..xff]>' to do what he expects
moritz eric256: normally [particle] gives quite good answers, give him another chance ;-)
[particle] had the plaster in his office blown off the walls by insulation installers today. he's more than a bit frazzled
19:58 stevan__ joined
moritz jisom: perhaps define a rule for that? 19:59
eric256 hehe lmao
sorry about the plaster particle, but that is a funny image (i was laughing about your "this IS perl6" ;) 20:00
groups.google.com/group/perl.perl6....ba937bd73f seems to talk about sets, but i'll be darned if i can tell if they've been included, or not, or morphed into something else

jisom I'm a little surprised not to see a "ascii" rule
eric256 yea i was amazed my account didn't get pruned after the 8 months of innactivity, trying to catch up on the changes since then is....daunting
