cognominal_ TimToady, I don't see the reciprocal of the ** match operator. I would have expected <1 2> ** ', ' eq '1 , 2'. I know about join, but with the parentheses, it is very verbose 01:26
01:26 agentzh joined
cognominal_ Also can 'given' be an expression instead of a statement? 01:27
01:28 cognominal_ is now known as cognominal
TimToady use 'do given' for that 01:29
cognominal thx
01:30 ash_ joined
TimToady otherwise we can't tell it from a 'given' modifier easily 01:30

TimToady rakudo: .say given "hi here" 01:31
p6eval rakudo 3867ff: hi here␤
cognominal I did not know about the given modifier.
TimToady similar reasoning for if, while, etc
cognominal makes sense to me.
diakopter backwards xargs? 01:33
TimToady he doesn't like <1 2>.join(', ')
though there's <1 2>.join: ', '
doesn't save any chars though
diakopter 1 fewer keypress? 01:34
std: say ... ... ... ... ... ... 3 01:35
cognominal as for readability, spaces should count as half a char
p6eval std 29527: ok 00:01 105m␤
TimToady but the lack of a closing bracket can detract from readability, if there is doubt about where the construct ends
hence we provide both () and : 01:36
cognominal anayway if I want ** as a join operator, whith multimethods I can get it.
TimToady you can, though it does violence to the usual ** concept

jnthn finds #perl6 strangely quieter these days. 10:02
jnthn blames it partly on ENOMASAK 10:04
;-)
frettled :) 10:16
ENOMASAK - core quiet
10:17 lestrrat is now known as lest_away
mathw a channel I'm in that's full of friends does a similar thing when one particular member is on holiday 10:38
in those circumstances we can go an entire day without filling a screen 10:39
strange how a community can revolve so strongly around one person 10:40
jnthn: have you started thinking about Perl 6 again yet? 10:41
jnthn mathw: Well, I got all of S06-signature/type-capture.t to pass again yesterday
Which felt like it was involving thinking. :-)
If I don't find more blocks (lack of type captures was the blocker I found yesterday and resolved) I hope to put parametric roles back in todya. 10:42
*today
mathw wheee 10:45
I assume you mean to pass in ng
jnthn Yes.
ng: sub foo(::T) { say T }; foo(42)
p6eval ng 393c45: Int()␤
jnthn Oh, I put type checking on scalars back too.
mathw yay 10:46
jnthn But that was mostly easy.
mathw extra yay
if that was mostly easy, there must be something done right in ng :)
or you're a genius, and your definition of easy is completely different to everyone else's
jnthn Well, it was easy 'cus I'd already put back variable trait mods. ;-)
mathw :) 10:47
Might we get ng for a release before too long?
Rakudo * is starting to look quite close from this side of 2010
Maybe I should help :) 10:48
jnthn It's hard to say.
I can put back lots of stuff but we're hurting for the list/iterator interface bits getting sorted out.
Which pmichaud has spent plenty of time looking at and thinking about and understands...whereas I've thus not worried about thinking about it much. 10:49
mathw So we all need to go to his house and feed him a continual supply of delicious caffeinated snacks until he's done it? 10:50
jnthn Havne't seen pm around yesterday though.
Something like that. ;-)

meneldor and the first one is in @*ARGS[0] ? 12:04
moritz_ yes
meneldor tnx
hejki meneldor: if you're doing simple argument parsing, you might want to use sub MAIN
meneldor how? 12:05
yes i need simple parsing
hejki e.g. [hejki@cornix ohjelmointi]$ perl6 -e 'sub MAIN ($x) { say $x+2 }' 8 12:07
10
moritz_ though rakudo's support is very limited 12:08
perl6 -e 'sub MAIN(@*a) { .say for @*a }' foo bar
No such attribute '$!do'
hejki that's why i said "simple argument parsing" :)
using sub MAIN {} even with lacked support is still more perl6ish than parsing @*ARGS 12:09
IMO :)

16:44 rgrau` left
TimToady I need an eyetracker for that... 16:45
I wonder how long till TVs track all the faces watching and send different pictures to each eye so 3D glasses are not necessary 16:47
that would be a real eyetracker :)
soupdragon with these new 3D films I think people will want that sooner
although I guess not for a long time after polarized lenses.. 16:48
maybe we will GM ourselves so that we have naturally polarized eyes
diakopter yeah; polarized contact lenses. left vertical right horizontal
TimToady only if you can change the polarization at will
I'd want mine vertical most of the time; I always wear polaroid shades outside 16:49
but I don't think that's what we'll end up with for 3D tv; we need the equivalent of directed beam radars, only in the optical range 16:51
diakopter currently std/cursor is constructing patterns for the prefixes and bruteforcing to get the longest? 16:52
TimToady just think how efficient a TV could be if it only had to make light for your eyes, too

TimToady: you're thinking that cursor/std will run its own re engine? 16:58
16:59 justatheory joined 17:00 meneldor left
TimToady eh? it already does...how do you think it parses? 17:01
it doesn't use P5 regexes except incidentally to do character classes and such 17:02
diakopter I thought it emitted the prefixes to perl5 regexes. OH
TimToady it recognizes individual bits of constant token with p5 regexes, but it could just about as easily use substr() for that 17:06
all the hard stuff bypasses the p5 engine entirely, because it wouldn't work 17:07
diakopter I thought you couldn't have hard stuff in token prefixes 17:08
TimToady \w+ is hard
diakopter oh.
TimToady I'm not talking about LTM here, but the engine that LTM determines the fates of 17:09
diakopter oh 17:10
TimToady LTM is currently emulated with p5 regexes, but that just determines the non-deterministic bits of the real regex matcher, which isn't p5
well, isn't p5 regex
see STD.pmc and the methods it calls for the actual regex engine 17:11
diakopter ah. I was imagining the LTM emulation being reworked.
TimToady well, yes, that wants to get to be less hacky, and that's what I was thinking about
17:12 pmurias joined
TimToady separating out all the longest methods to a separate file yesterday was part of that refactoring 17:12
17:12 cdarroch joined
diakopter ... to find the longest token by reversing each of the prefix patterns, sorting them by the ltm priority rules, then merging them into one alternation in reverse priority order, then prepend the whole pattern with ^(?:.*?) 17:14
... and matching it against the input string, reversed and truncated to the input spot. 17:15
current offset spot, I mean
sorting properly would be the tricky part. 17:17
TimToady you can't always tell which of two prefixes will end up longer by inspection
diakopter hm. in that case, you'd have to flatten/expand out all the nested alternations. 17:18
sigh
I thought I read somewhere that it's possible to calculate whether a regular pattern is subsumed by another 17:22
TimToady that's fine if you don't care which pattern matched
we do 17:23
diakopter one could determine that by creating a globally indexed capture for each alternation... ick. 17:24
(and keeping track of which pattern ended up in which slot)
TimToady that's more or less what tagged dfa does, but the tdfa I played with require 17MB of stack space on every token, ouch 17:25
*required
diakopter :o 17:26
TimToady was also a buggy academic toy, so I abandoned it
diakopter batty
TimToady I just plan to mutate my trie implementation into a parallel nfa that caches all recognized tokens in the trie so that the second time we see a particular identifier, it's fast 17:27
and each trie node knows which patterns it has pointers into if the current character doesn't match 17:28
but it only has to traverse those for strings it hasn't seen one of yet
17:29 cognominal left
TimToady currently the LTM just runs all the funny patterns at the beginning and sorts the results, but that's because I can't track intermediate match states on them yet 17:29
when I can keep sets of positions into patterns, I can distribute the parallel match down the trie 17:30
17:30 skeptical_p joined, skeptical_p left 17:31 skeptical_p joined
diakopter hm 17:31
TimToady (probably with some limit on the trie size to avoid explosion on non-recurring texts
at some point it starts behaving more like egrep
and only caches recent state sets 17:32
that's been my plan for a long time now, but I keep having to do silly things like design the language... 17:33
and the current LTM prototype is good enough to have the correct semantics, if slowly
jnthn An irritating distraction. ;-)
17:34 ash_ joined
jnthn hi ash_ :-) 17:34
ash_ hi
jnthn I'd already gone to attempt sleep by the time you wrote some more questions last night, sorry.
ash_ i think i got the method forwarder working now, so my patch is done, with some testing first of course
jnthn \o/
Great.
ash_ no worries
17:35 barney left 17:36 ruoso left
ash_ some of the parrot stuff you did in master i am not completely comprehending, but i think i get the gist of it, for your forwarder 17:36
jnthn Yes, we hide Parrot away behind the metamodel now rather than twiddling with it too directly.
I need to deal with one other $work task and then make some dinner, so I'll probably have time to focus on looking at your patch and hopefully applying it in a couple of hours. 17:37
ash_ how does .lex work? i am having 1 issue with that, creating a closure in parrot for the forwader 17:38
i am on campus at my school and for whatever reason the perl.org irc server won't let me connect 17:39
so i can't get to #parrot
jnthn If you want to see a really simple example of that, see assuming (maybe just in master, not sure if we did also put it ng yet)
17:39 pmurias left
jnthn But basically... 17:39
.lex '$foo', $P0 associates the register $P0 (you can use a symbolic one too) with the name $foo
You then make your inner thingy that you're going to return have it's :outer('...') match the subid of the thing that generates the closure 17:40
And then you can do x = find_lex '$foo'
But be sure to call newclosure as well (in the closure generator) to make sure you get a clone attatched to the right outer scope 17:41
Also I did such a thing in src/metamodel/Attribute.nqp
If you look at how the PIR falls out of that, that may give you more clues.

ash_ gist.github.com/275400 so, right now, the Foo.^bar form works, but the forwarder gives: Lexical '$meth_name' not found 17:45
do you see anything i just did wrong?
jnthn hmm, don't immediately see a problem 17:47
Maybe add a :subid('ClassHOW::add_meta_method') and reference that in the :outer though?
In case it's picking up some other add_meta_method
so it's 17:48
.sub 'add_meta_method' :method :subid('ClassHOW::add_meta_method')
and then :outer('ClassHOW::add_meta_method')
below
You have an add_meta_method elsewhere, so probably best to disambiguate. :-)
ash_ alright, i'll try that 17:49
i realize the only difference between your master version and the one i made for ng is i use HOW.HOW's add_method and you do an 'infix:does' 17:50
hmm still getting that error
17:52 jackyf joined
ash_ what if i declare the .sub as a :lex 17:54
17:54 dakkar left 17:55 stephenlb joined
jnthn ash_: You shouldn't have to do that if you have a .lex in the sub itself. 17:55
Oh wait, you mean the inner one... 17:56
Hmm, but try that, but again, I don't *think* that'd make a difference.
ash_ i am having trouble finding much documentation on :lex, but it is mentioned in the PIR book chapter 6 on sub's 17:57
jnthn Yeah, I've never used it as far as I can remember, I think it's for if you have a more dynamic lexpad rather than use .lex 18:00
PerlJam Based on the ack I just did of my parrot working copy, there's not a whole lot of info on :lex 18:01
ash_ Languages where this information is not available can mark the subroutine with :lex instead. /from chapter 6 of pir book 18:02
in regards to .lex 18:03
so, i guess it has something to do with the language lexical rules vs parrots lexical rules?
18:03 r0bby left 18:04 r0bby joined
ash_ would find_dynamic_lex be any better than find_lex? 18:04
i assume they have different lookup rules
jnthn No, find_lex is what we tend to use for this. It looks like it should work, which is odd. :-/ 18:09

jnthn TimToady: Any thoughts on this? 21:00
TimToady: I've kinda been treating the thing in the namespace as always being the thingy that knows about all of the roles, and if you try and do that somewhere, it knows to disambiguated itself through doing Foo[]. 21:02
*to disambiguate
Having Foo (all of em) and Foo[] / Foo[Int] etc (particular disambiguated forms of the role) pretending to be the same thing feels a bit awkward in a "trying not to just cheat and lie" world. :-) 21:03
A Perl 6 level way (rather than just a guts one) to know which we have would allow me to make things a little less magical anyways. 21:07

jnthn They're all Code but not all Sub.
spinclad right 21:14
jnthn Which is why I'm wondering if there's a "3 things" situation for roles.
spinclad so is Role like Code or like Sub?
jnthn And if it's like Code, what are the names of the other two things? :-)
I think we need to have a way to disambiguate, anyways, for the occasions people will care. 21:15
spinclad i somewhat think of Foo as (*args -> Role) and Foo[Int] as the resulting Role... 21:16
so in that sense different types
jnthn Yeah 21:17
That's my kinda feeling too.
spinclad i would like to definitely think that, with the Specs saying so
jnthn Better than trying to paper over the difference, imo.

sjohnson PerlJam: i suppose if you wrote a quick script to pass it to a std-like local rakudo thingy 22:44
to run it if it's valid
jnthn ash_: I've spent my evening debugging and sorta fixing parametric roles - I'll take a shufty at your patches and try to debug 'em tomorrow.
ash_ alrighty, did they apply cleanly for you? 22:45
jnthn ('cus I'm tired now)
I didn't try yet, but I don't think anything I've done will cause them not to. Or at least, I hope not.
sjohnson thanks PerlJam
PerlJam rakudo: <piggy bird rooster>>>.uc.perl.say; # this is the one that's likely to cause people fits :)
p6eval rakudo 3867ff: ["PIGGY", "BIRD", "ROOSTER"]␤
sjohnson wow that's a neat trick
rakudo: <piggy bird rooster>.uc.perl.say;
p6eval rakudo 3867ff: "PIGGY BIRD ROOSTER"␤ 22:46
sjohnson what were the extra two >'s for PerlJam ?
PerlJam sjohnson: obfuscation! :)
ash_ hyper operator
sjohnson heh
22:46 r0bby left, r0bby joined
sjohnson i'm a fan of thast obfuscation stuff 22:46
22:46 meppl joined
sjohnson saw some interesting perl 5 japh's 22:46
jnthn sjohnson: If you have @list>>.method then it calls method on every item in the list and makes you a new list of results.
PerlJam rakudo: <piggy bird rooster>.>>.uc.perl.say; # clearer but still makes you think 22:47
p6eval rakudo 3867ff: ["PIGGY", "BIRD", "ROOSTER"]␤
22:47 soupdragon left
sjohnson is the >> operator unncessary though? 22:47
ash_ its required 22:48
sjohnson i did it without it though ash_
jnthn sjohnson: .uc coerced the list to a string and uc'd the one string.
sjohnson rubs eyes 22:49
oh
i c
didn't see those quotes
ash_ sjohnson: notice in your's its 1 big string, not 3 strings in a list
jnthn rakudo: <a b c>.uc.WHAT.say
p6eval rakudo 3867ff: Str()␤
sjohnson good eye!
jnthn rakudo: <a b c>>>.uc.WHAT.say
p6eval rakudo 3867ff: Array()␤
22:49 soupdragon joined
sjohnson irc colour coded quotes for the .perl thing would be pretty k3wl 22:49
might be too cool for school tho 22:50

ash_ so, jnthn if i did (in pir), $P1 = newclosure $P1 \n say $P1.'get_lexinfo'() shouldn't that print out the lexical variables of the closure? 22:54
jnthn no, it's a parse error... 22:55
PerlJam ash_: you can only say/print simple things.
ash_: PIR is assembly after all.
jnthn $P0 = $P1.'get_lexinfo'() and then say $P0 may do something
but probably nothing quite that useful.
I forget what that exactly returns.
ash_ it says it should return a hash
jnthn OK
In that case you can probably iteratre its keys to see what's in there. 22:56
ash_ I just am trying to see find some way to see why find_lex '$meth_name' dies
jnthn Yes, I'm a bit confused about that too. 22:58
I'll dig deeper tomorrow.
ash_ kk
jnthn ('tis about midnight in my $timezone now... :-))
ash_ oh, well, dang, you stay up late then if i keep seeing you online at this thime 22:59
22:59 iblechbot left
jnthn ash_: Oh, I'm certainly an evening person. 23:00
ash_: I've got a phone meeting tomorrow morning though, so can't stay up *too* late tonight. :-) 23:01
ash_ do you work on rakudo full time or is it something you do on the side? 23:02
jnthn ash_: It's been somewhere between the two over the last year really. 23:03
ash_ got ya, just wondering 23:04
jnthn I've not had a full time job, just consulting, and between various jobs and some grants to work on Rakudo, I've managed to keep food on the table and be able to go travel a bit.
sjohnson rakudo: say "40".pack
jnthn In March I am joining a company, which means I won't have to worry so much about where my next bit of work is coming from. 23:05
p6eval rakudo 3867ff: Method 'pack' not found for invocant of class 'Str'␤in Main (file src/gen_setting.pm, line 324)␤
sjohnson rakudo: say pack("c", 40);
p6eval rakudo 3867ff: Could not find non-existent sub pack␤in Main (file src/gen_setting.pm, line 324)␤
PerlJam jnthn: a rakudo-friendly company?
jnthn PerlJam: Yeah. :-)
PerlJam sjohnson: pack/unpack aren't implemented to my knowledge
jnthn PerlJam: I'm not going to be doing full time.
PerlJam: And they're very happy with me going to conferences. 23:06
PerlJam jnthn: yeah, but if you could get paid to work on rakudo, that's always awesome.
ash_ sweet, sounds like a goodjob
23:06 meppl left
jnthn PerlJam: The way it works out I kinda *do* need to do something that pays a bit in the remainder of the time, but yes, I'd like that to be Rakudo stuff. 23:07

ash_ how does interpinfo work? 23:09
PerlJam We need an Ian Hague type fellow to setup a business that needs rakudo and hire pm + jnthn :)
ash_ like, are there any examples i can reference, doing an ack "interpinfo" didn't get me much

jnthn ash_: oh actually 23:11
I think nicer is...
Tehre's a $P0 = getinterp op
iirc
23:11 justatheory joined
jnthn That gets you an object representing the interpreter 23:11
ash_ k, thanks, ill try that
jnthn Then you can do things like $P0['sub'] or $P0['lexpad']
And it's a much saner interface. 23:12
Not sane, but saner
See I think src/pmc/parrotinterpreter.pmc in Parrot source tree, get_pmc_keyed method or some such.
ash_: oh, here you go 23:13
docs.parrot.org/parrot/latest/html/...r.pmc.html
And getinterp is documented in docs.parrot.org/parrot/latest/html/...e.ops.html
So is interpinfo akshually 23:14
ash_ i am going to sign up for the google summer of code to work on parrot this summer, hopefully to implement an llvm stack frame builder, well thats my proposal anyway, this stuff is helping me learn about parrot a lot, plus i'd love to see rakudo star get as far along as it can before its supposed to be released
jnthn ash_: OK, cool.
ash_: There's likely projects within Rakudo itself as well - really depends on what you will find most -Ofun. :-) 23:15
ash_ interpinfo is confusing, what does it mean by the list of .CAPITAL_LETTERS 23:16
are those options? thats what i found confusing about it
jnthn They're constants 23:17
You have to .include them
Thus why I prefer getinterp
and then inspect that
ash_ k, i'll use that for now 23:18
jnthn k 23:27
jnthn -> rest, night
sjohnson rakudo: my @strs = " x ", "x ", "x", " x "; say @strs.trim.perl;
ash_ cya later
p6eval rakudo 3867ff: "x x x x"␤
sjohnson rakudo: my @strs = " x ", "x ", "x", " x "; say @strs.>>.trim.perl;
p6eval rakudo 3867ff: ["x", "x", "x", "x"]␤ 23:28
sjohnson intersting >> operator.. what do they call it?
TimToady it's not really an operator; it's a meta-operator 23:29
this particular meta-operator is called a hyper
a hyperop modifies some other operator to run in parallel over multiple values
when it would naturally only work on one value
in this case. the method call 23:30
is treated as a fancy postfix operator
ash_ you can do it the other way too
-« (1,2,3); # (-1, -2, -3) # from the spec 23:31
diakopter pugs: say -« (1,2,3); 23:32
p6eval pugs: -1-2-3␤
ash_ i don't think it works in rakudo though
ah, but it works in pugs, cool
sjohnson thanks TimToady and ash_ 23:33
TimToady: is there a pack(); func in p6? 23:34
ash_ its talked about in S03, so you know, the section on Meta Operators goes over the general meta ops and in there are the specifics of hyper
sjohnson: yes, in S32-Str they talk about it for strings, its not yet implemented though 23:35
sjohnson oic
TimToady ash_: you have to understand that sjohnson doesn't actually believe in reading docs. he intents to learn it all by asking questions here. :P
ash_ maybe i should respond with more links? :P 23:36
TimToady commuting &
sjohnson sorry TimToady :( but i will read them 23:37
just need to sit down, and do it
diakopter sjohnson: that's what I do too. 23:38
ash_ perl cabal's syn is searchable btw, perlcabal.org/syn
sjohnson TimToady: if i read the docs, i wont have the joy of having people help me anymore :) 23:39
