soh_cah_toa wouldn't need stupid goto if i could just interpolate an array index in a character class... :( 02:23
soh_cah_toa huffs and puffs
sorear um, what. 02:29
you can't interpolate anything in character classes, that's not how they work :|
what are you trying to do? 02:30
02:36 s1n left
soh_cah_toa i have an array @foo = <abc def ghi> and i want to check if some scalar contains any of the characters in the first element @foo[0]. however, i can't do `$something ~~ /<[@foo[0]]>/`. actually, i want to do this for @foo[0] and @foo[1] and another scalar string all in one character class 02:38
so like $something ~~ /<[$value @foo[0] @foo[1]]>/ 02:39
except that's illegal obviously
not in p5 though
02:41 beekor left 02:42 odoacre joined 02:44 ponbiki left
soh_cah_toa not sure why this would be illegal in p6. i can do what i want just fine in p5 :\ 02:47

soh_cah_toa well, i want it to match *any* of the characters in the string (in one of the array elements). not the entire string itself 02:50
02:51 s1n joined
soh_cah_toa except it has to be any of the characters in $value OR any of the characters in @foo[0] OR any of the characters in @foo[1]. thus, a character class should perform exactly that task 02:53

lue Not pretty, but perhaps it'll do? [Unless you *need* to use a regex, that is]
afk
soh_cah_toa i think i get what you're doing but $a should be a string like 'abc' and see if any of them are a match 03:00
what does .comb() split on by default? <alpha>? 03:02

soh_cah_toa odd, i thought the <> was reserved for named regexes? how does it behave w/ an array? 04:02
TimToady ooh, even does ltm
there are many, many things that can go inside <> 04:03
sorear yikes, rakudo is ahead of niecza at something, need to fix 04:04
TimToady soh_cah_toa: see perlcabal.org/syn/S05.html#Extensib...%3C...%3E) 04:05
sorear TimToady: do you think it makes any sense to allow variables in character classes?
I'm on the fence
character classes feel very literal-y to me
04:05 dark_x joined
sorear niecza has a lovely O(log n) implementation of character classes that requires pre-analysis 04:05
TimToady rakudo: my @x = <a ab c>; say "cab" ~~ /<{@x.join('|')}>*/ 04:06

p6eval rakudo a55346: OUTPUT«cab␤»
soh_cah_toa i don't see why it shouldn't. whatever the variable holds would be interpreted as literal characters
TimToady there's another way
soh_cah_toa my $foo = 'abc'; /<[$foo]>/; would be the same as /<[a b c]>/
TimToady I think if there are so many ways to generate an any match already without resorting to eval, we should probably keep the char classes literal 04:10
there's also defining your own character properties 04:11
then it's just <+myprop>
I don't think we need to retreat to P5's confusion of regexes with strings
soh_cah_toa a valid point 04:12
TimToady a lot of this redesign is just gut feelings
but I can come up with lots of rationalizations for my gut feelings :) 04:13
soh_cah_toa :)
TimToady 'course, it's not exactly specced yet how to make your own character properties... 04:14
"a topic of ongoing research" :)
this may fall out of actually implementing Unicode properties natively, though
soh_cah_toa i was just gonna ask that. what's a character property? never heard of that 04:15
TimToady well, something like <alpha> 04:16
or that's supposed to be <:alpha> now, actually
Unicode defines skadillions of character properties
things you get at with \p and \P in p5 04:17
soh_cah_toa oh, i thought <alpha> was just a character class 04:20
TimToady a great deal of Unicode is "just character classes" 04:21
but p5 is still rather far ahead of p6 on Unicode classes 04:22
anyway, S05 is well worth a gander, since regexen are the parts of perl that are most heavily redesigned in p6 04:24
and the whole p6 grammar is basically a set of fancy regexes
soh_cah_toa yeah, i've yet to get through the whole thing. it's the size of an encyclopedia
TimToady you can stop when it starts enumerating all the different capture cases, unless you're interested 04:25
04:26 daniel-s joined
TimToady well, usually listing the differences from p5 makes a shorter document, but in this case, it's probably longer that way :) 04:26
the grammar is a good example to learn from, if you learn from examples, but it won't tell you much about the bits that haven't been implemented yet, which haven't been because the parser doesn't need them yet :) 04:28
soh_cah_toa indeed
TimToady there are things like hard-wired lists of brackets that should be using Unicode properties 04:29
soh_cah_toa well, time to call it a night 04:32

lue Hm. I can't seem to find where := and ::= are currently implemented in Rakudo. (according to NOMMAP it could use some fixing, and I'd like to see if I could do it.) 07:07
nevermind, I think I found it (Actions.pm, right?) 07:12
moritz right
sorear try to do it even better than the last time you did it 07:13
moritz sorear: in rakudo I'm now using a trait (is hidden_from_backtrace) to hide certain routines from backtraces (notably &die for now) 07:17
sorear: have you spent any thoughts on how you want to do that in niecza?
sorear moritz: no, but I like that one
moritz sorear: background of the question is that I want to know if you think it's sensible to spec that
sorear moritz: niecza already uses something similar for test failures 07:18
moritz sorear: care to explain a bit more?
sorear it prints something like (callframe(), *.caller ... *).first(!*.hints('$?TRANSPARENT')).line
moritz ah, ok 07:19
sorear the top of Test.pm6 has my constant $?TRANSPARENT = True; so not ok skips all Test lines 07:20

can I somehow reuse a grammar token, but with a different action method? I'd like to handle colonpair a bit differently in Pod blocks configuration 11:21
11:22 pernatiy joined
moritz well, you can do 11:23
token my_colonpair { <colonpair }
and then do another action in the my_colonpair action method
tadzik but the colonpair() action method will still be called, and I'll only have access to what it returns, not to colonpair internals like $<key>, $<value> or so 11:25

moritz why can't what be Q:w?
abercrombie Q:w /a $a c/ let $a get interpolated 15:38
moritz because that's not consistent, and not what you asked perl to do
I mean, why must it be Q:w when qq:w does it, and is consistent with all other uses? 15:39
abercrombie I read that :w is for "Split result on words (no quote protection)"
moritz yes, and it's not "interpolate scalars"
that's what :s gives your 15:40
abercrombie Oh, I thought "no quote protection" means it will interpolate variables
moritz no, it means that it's split on quoted whitespaces too
'a b "c d" e' -> 'a', 'b', 'c d', 'e' would be with quote protection 15:41
and without it: 'a', 'b', '"c', 'd"', 'e'
moritz -> decommute

moritz oh 18:22
moritz looked at the wrong version
jnthn It matters because in Code.pm it "does Callable"
And if Sub.pm comes earlier, then it computes its type cache without Callable in it.
moritz so I need to try to shuffle it around enough to make it work :/ 18:23

TimToady perhaps caches need to be recomputable; most caches these days allow write-through :) 18:30
jnthn TimToady: Already on the todo list. :) 18:32
Plus you can already force a re-computation at any point you like, but I don't want anybody in user space to ever need to do that. 18:33

dakkar can we raise some funds to have them both in the same room and film them while they argue?
tadzik and plush cthulus 20:13
Su-Shee: thanks, that's funny :) 20:14
Su-Shee "hm. hm." 20:15
tadzik can I .flat those tweets somehow?
Su-Shee uff. now I have my observer in Moose. next, I will have one in rakudo. 20:16
dakkar tadzik: not easily, there's no Twitter API call for "give me a conversation" 20:17
tadzik shame
diakopter tadzik: click the arrow on the upper left of chromatic's top post
moritz tadzik: I've opened twitter.com/#!/chromatic_x and twitter.com/#!/shadowcat_mst in separate tabs
diakopter tadzik: upper right I meant
masak also, chromatic doesn't seem to use the "reply" function when he has conversations :(
tadzik diakopter: I did that, thanks 20:18
masak gaaargh New Twitter, you big piece of fail... 20:19
moritz masak: not surprising, since there's hidden meta data involved, which is very easy to miss
TimToady pray don't mind the missiles flying overhead; none of them is really aimed at us :)
jnthn :)
tadzik I have a feeling that chromatic++ still has mixed feelings about Rakudo targeting different VMs, and mst++ is defending the idea 20:20

not very mixed, IMO.

[Coke] Yup. It's hard to fault teamRakudo for pursuing it. 20:28
I do find the whole perl6/parrot thing confusing, myself. far too organic, not enough BDFL.
Su-Shee "BDFL"? 20:29
PerlJam Su-Shee: pythonism -- Benevolent Dictator for Life
masak well, Parrot is a foundering project on top of a wonderful vision. meaning, it could still be great if it gets its act together. M0 could be that, who knows? 20:30
PerlJam [Coke]: the problem with that is that the BDFL is driving blind too :)
diakopter PerlJam: curious who's the BDFL
masak .oO( Oracle seems to be finding their niche as a MDFL... ) 20:31
PerlJam masak: whiteknight is fixing things. He seems to be pointing Parrot in the right direction. Let's hope he never tires of it until Parrot is "finished" :)
tadzik this twitter thing is weird. It's smart enough to display "2 new tweets", but not smart enough to just display the tweets 20:33
[Coke] I dislike the default web app. :|
PerlJam tadzik: I've thought that forever. 20:34
[Coke] I would prefer a model where they were automatically added, but scroll locked at the last one until you moved it. 20:35

22:37 im2ee left
tadzik since $.foo attrs are not writable now 22:37
jasonmay oops :) 22:38
tadzik the only way to avoid this, which comes to my mind, is the setter method in a role
not sure how this should be handled
22:39 jevin joined
tadzik there or another way we expose the atribute writeness to the outside world, which we don't neceserilly want 22:39
jasonmay if there is code smell in my module let me know, I'm open to implementations
tadzik not sure 22:40
jasonmay I based it off my perl5/moose fu :)
& for an hour or so
tadzik I guess we could have an initialize() method in a role, which will die if we initialize an already initialized attribute
