kthakore how do I do qx interpolation properly?
eternaleye kthakore: You did it properly, but it's disabled for security reasons
00:15 Hale-Bopp joined
kthakore oh 00:15
yayayay
00:16 ascent_ joined, icwiener_ left
eternaleye Although, qx runs thins in the shell, not perl6 00:16
so qx/echo foo/ would work, but qx/say foo/ would only work on OSX (and even then, it would make the word 'foo' come out of the speakers on the computer 00:17
kthakore ok I have a real question now. I am currently working on SDL_perl for perl5 and I noticed a parrot implementation in CPAN. Can the parrot implementation be used in p6
? 00:18
eternaleye I think so. There have been a few demos using OpenGL directly, but I don't know if anyone's used SDL in Rakudo. You could try 'use SDL:from<parrot>'
00:18 buubot joined, jhelwig joined
Tene kthakore: Yes. 00:18
eternaleye rakudo: use SDL:from<parrot>
p6eval rakudo 24b26a: OUTPUT«libSDL not found!␤in Main (src/gen_setting.pm:445)␤» 00:19
kthakore hmmm ....
Tene sdl isn't installed on feather
kthakore so if I wanted to have a common bind between p5 and p6 for SDL. Is parrot or p5/XS better? 00:20
japhb And there's no point trying to use SDL remotely ....
kthakore japhb, lol
eternaleye japhb: I was mainly checking if it would load
00:20 ruz_mac joined
kthakore unless if rakudo can beam it to my Xserver 00:20
Tene kthakore: parrot doesn't interoperate with perl 5 at all.
kthakore Tene, no I mean
for p6 SDL module
is c -> parrot -> p6 or c -> p5 -> p6 better? 00:21
eternaleye kthakore: XS doesn't work on parrot. It uses something different called NCI
kthakore eternaleye, noted above
eternaleye and p5 -> p6 doesn't work yet
kthakore eternaleye, ok
thx
Tene kthakore: p5 -> p6 isn't an option
kthakore back to hacking ...
Tene ah, too late
kthakore lol
thx for rakudo bot
japhb So yes, you want to use the Parrot one. The problem is that not all Parrot libraries have been brought up to date with current spec for loading from HLLs (High Level Languages) 00:22
work in progress, that.
kthakore okie 00:24
ps we are WIP too . github.com/kthakore/SDL_perl/tree 00:25

wayland76 Ok, this is really cool :) 03:23
I'm converting a program from P5 to P6, and it's eliminating half my code
Just because it has a proper OO system :) 03:24
03:36 kane_ left
missingthepoint wayland76: i can relate, i'm trying to port text::csv, and P6 means a LOT of OO junk can be eliminated 03:39
wayland76 Well, I should've really mentioned the "subset" feature
That's actually eliminating more code than anything else :)
missingthepoint subset? 03:40
wayland76 my subset Str_not2b of Str where /^[isnt|arent|amnot|aint]$/;
(That example is from the docs)
missingthepoint does that work in rakudoL
err, ?
wayland76 There was a lot of code keeping out illegal values
Not sure
But I tend to code in P6, and only do workarounds where I have to 03:41
When I hit bugs, if there isn't an obvious workaround, I tend to block on them
rakudo: my subset Str_not2b of Str where /^[isnt|arent|amnot|aint]$/;
p6eval rakudo 24b26a: ( no output )
missingthepoint think you need to instantiate sometthing there... 03:42
wayland76 rakudo: my subset Str_not2b of Str where /^[isnt|arent|amnot|aint]$/; my Str_not2b $text; $text = 'amnot';

p6eval rakudo 24b26a: OUTPUT«Null PMC access in type()␤in Main (/tmp/XTmpf80pmG:2)␤»
wayland76 I'll take that as a "no" :) 03:43
It parses, but fails to run
missingthepoint wonders how it parses 03:44
wayland76 Well, there is that too :)
Why are you doing Text::CSV? Do you need it, or were you looking for a project? 03:45
03:45 zamolxes joined
missingthepoint Pm wanted it 03:45
(well, something to handle CSV data)
and it sure is a great way to find rakudobugs.
wayland76 Yeah, I've submitted more rakudobugs in the last week than ever before 03:47
Actually, maybe only the same
03:47 ancients left
wayland76 (2 over the past year, then two this last week) 03:47
Once I get this project to a sticking point, though, then I'll have to work on some of the Rakudobugs myself if I want to make any progress 03:48
I don't know PIR, though
03:48 ancients joined
wayland76 Or Rakudo's internals :) 03:48
missingthepoint it's fairly easy... have a look at the book on parrot.org 03:49
good docs are good
docs.parrot.org/parrot/latest/html/
"Book PIR"
just added i think
eternaleye rakudo: subset Negation of Str where { /^[isnt|arent|amnot|aint]$/; } my Negation $text; $text = 'amnot'; say $text; $text = 'yesiam'; say $text; 03:50

eternaleye Hm
wayland76: You could use enums
wayland76 Yeah, in many cases I could 03:52

p6eval rakudo 24b26a: OUTPUT«Statement not terminated properly at line 2, near "'; $foo = "␤in Main (src/gen_setting.pm:3363)␤»
wayland76 In fact, maybe I should. But I think this code will block on a lot of different things, so I'll only do it if I end up blocking on them
eternaleye rakudo: enum Negation <isnt arent amnot aint>; my Negation $foo; $foo = 'isnt'; say "$foo"; $foo = 'yesiam'; say $foo

Su-Shee good morning. :) 07:15
moritz_ Su-Shee: good morning; you just missed my advertisment: perlgeek.de/blog-en/perl-6/rakudo-s....writeback 07:17
07:20 donaldh left, donaldh joined
missingthepoint moritz_: VERY nice article. 07:22
moritz_++
Su-Shee moritz_: nice. I see a bright future in perl marketing. ;) 07:23
missingthepoint :) 07:24
07:24 rfordinal joined
Su-Shee is going to fix the perl6 projects layout until the end of the week. I was thinking to make two download buttons (1) parrot, 2) rakudo - one needs both afterall...) 07:24
missingthepoint Su-Shee, good idea... since Pm is planning to move to building against installed Parrot 07:26
Su-Shee exactly. why force people to click two sites if they can have two download buttons. :)
07:26 icwiener-_- left
missingthepoint Su-Shee: did you do the p6p.org design? 07:27
wayland76 Ooh, the dead lives again! (#perl6 revives) 07:28
Su-Shee missingthepoint: yes.
07:29 finanalyst left
Su-Shee missingthepoint: but I didn't invent the colouring of the butterfly! :) 07:29
moritz_ missingthepoint, Su-Shee: thank you 07:30
missingthepoint moritz_: np 07:31
Su-Shee: as someone who's been exposed to many website designs, that's a good one. Su-Shee++
and I do think camelia is a little bright for a language logo... but maybe that's apt :) 07:32
Su-Shee If I get a nice idea, I'll make some buttons like "rakudo love" and "I code butterflies" or something like that (contemporary version of "this site is made with vim" ;)
moritz_ you can still de-colorize it
Su-Shee: that's a nice idea 07:33
Su-Shee moritz_: it's very memorable and NOT "hey, we're technology, let's make this site dark blue like everybody else" ;)
missingthepoint Su-Shee: that has me giggling!
i like 07:34
Su-Shee moritz_: and it's also "cute" enough to make p6 look less intimidating. ;)
moritz_ I'd also love to seem some Perl 6 "corporate identity" styles that people can use to design their Perl 6 sites
Su-Shee moritz_: that's not easy - will it be a camel again? take the butterfly? go with the "do" theme? 07:35
moritz_ currently rakudo.de and perl-6.de are stuck with their (non-)designs and I have no idea how to style them
Su-Shee: camel is dangerous (copyright by O'Reilly)
Su-Shee: what is the "do" theme?
missingthepoint avoid camel
Su-Shee moritz_: raku do ("path", "way" in japanese) 07:36
I was thinking along the line of a monk with a parrot on his shoulder. ;)
tann_ nice post, moritz
moritz++
ancients is away (4[O.F.F.L.I.N.E]) 07:37
07:37 ancients is now known as [ancients]
moritz_ Su-Shee: I was thinking of something rakudo agnostic (not all Perl 6 is Rakudo), but that would be a good start nonethelss 07:37
[ancients]: please don't announce that publicly, that's not very interesting for us
tann_ not that 1 more karma point would help moritz achieve nivarna any sooner
07:38 rfordinal3643 joined
Matt-W tann_: it's like zeno's paradox 07:38
moritz_ as the perlmonks quibs say "A journey to 1000 XP begins with a single point"
wayland76 moritz_++ for the article
Su-Shee moritz_: the interesting question will be: make a a) perl 6 CI and b) a rakudo one? Or make something which can take "perl 6" CI and transform it easily into rakudo, pugs, sexysixnew, whatever.. 07:39
.oO(sexysix.org ;)
moritz_ something transformable would be awesome
wayland76 moritz_: I suspect that ancients' IRC client does it for him
missingthepoint wayland76: i doubt his client puts in O.F.F... 07:40
(but i could be wrong, there are more obnoxious things on the internet)
moritz_ Su-Shee: already taken :(
missingthepoint moritz_: let me guess...
07:40 sri_kraih left
wayland76 missingthepoint: I'm thinking he's programmed his client to do it 07:40
moritz_ well, IRC clients are configureable
Su-Shee moritz_: too controversy anyway. ;)
moritz_ missingthepoint: seems to be SFW 07:41
missingthepoint wayland76: exactly my point :)
moritz_: H==W, :)
tann_ it's heart-warming to see a set goal for perl 6 through rakudo ... dammit, i should quit spending hours playing at work and instead, use 'em on patching rakudo :) 07:42
missingthepoint tann_: i agree.
Pm++
Matt-W if only 07:43
Matt-W is considering looking for another job, but doubts there's 'full time Perl 6 developer' available anywhere yet
tann_ Matt-W: indeed, those dudes keep challenging me at the pool table :)
wayland76 Matt-W: If you find one, I'll fight you for it
Su-Shee Matt-W: I think we have to found those companies on our own within the next years. 07:44
Matt-W: which leads to the more serious question on how to place Perl 6 as a "future programming language". 07:45
wayland76 tann_: Tell them you'll play them every day for a week if they make a Rakudo patch
tann_ wayland76: unfortunately, they're all java sellouts :)
Matt-W tann_: tell them that Perl 6 improves their pool
boooo
lots of java at my work too 07:46
Matt-W scowls
wayland76 Tell them you like Perl 6 because it does objects better than Java :)
And it's more readable :)
(What are the other hot buttons for Java people? :) )
Matt-W operator overloading
tann_ not only do i have to withstand the ridicule on my pool skill, i also suffer from lots of java preaching :)
Matt-W unless they've swallowed the dreadful Java philosophy that they cause more trouble than they're worth 07:47
roles
multiple inheritance
anonymous functions!
closures!
moritz_ closures with just two characters!
Matt-W exceedingly flexible foreach loops
tann_ and the masterpiece autoboxing :P 07:48
Su-Shee "yes, but where are the support contracts?"
wayland76 Matt-W: I know they're cool features, but do Java people have them as hot buttons (I mean ways in which they think Java is better)?
Su-Shee "and students don't learn it at university, how do I find developers?" ;)
Matt-W wayland76: closures are something lots of Java programmers wish they had
moritz_ Su-Shee: point them to www.rakudoconsulting.com/main.html
Matt-W Su-Shee: you hire clever people who can learn it
07:48 eiro_ is now known as eiro
Matt-W students don't learn Java at university anyway 07:49
they're told they do
but they don't really
wayland76 Su-Shee: Tell them that that means that only good people know P6, unlike Java :)
tann_ agree
Matt-W university puts you on track to learn how to program
tann_ my college only offers programming language classes as self-paced courses :) 07:50
Matt-W and, hopefully, gives you a solid theoretical basis for it
Su-Shee well that are the arguments I hear in job interviews or from CEOs.
Matt-W Su-Shee: yes unfortunately they went to university and think they know how to manage programmers...
Su-Shee Matt-W: sometimes, unfortunately c.s. techs from university think they can do business and manage people. :)) 07:51
tann_ actually, it varies from one school to another though
wayland76 Is $/ supposed to be the last Match?
tann_ some schools teach "database" classes strictly as playing with SQL :)
moritz_ wayland76: aye
wayland76 Hmm. Because I've got soemthing like: /^(\w+|Configured with|Thread model)\:(.*)/ and do { say $/[0]; } 07:52
07:52 rfordinal left
wayland76 And the "say" part says: Method 'postcircumfix:[ ]' not found for invocant of class 'Failure' 07:52
moritz_ that means it didn't match
wayland76 Ok, so why is i 07:53
moritz_ remeber that whitespaces in regexes don't mean anythiing
wayland76 ah
No, it matched
moritz_ put quote around 'Configured with'
wayland76 But I'm forgetting that the return value from // is not a boolean
moritz_ is it a different scope?
07:53 rfordinal joined
moritz_ it can be used as one 07:53
wayland76 ok
Anyway, it's matching Target: i386-redhat-linux 07:54
I think it matches the \w+ bit

pmichaud wayland76: +1 10:43
wayland76 Now that I have a Rakudo RPM, I've found more bugs in the last week than in the preceding year, I think :) 10:44
pugs_svn r27874 | lwall++ | [CORE.setting] add invert 10:46
r27874 | lwall++ | [Cursor.pmc] chop out much useless boilerplate
r27874 | lwall++ | [gimme5] translate invert -> reverse
r27874 | lwall++ | [gimme5] some viv -5 convergence

r27874 | lwall++ | [STD] check use of colon and closers for delims
r27874 | lwall++ | [STD] attempt to chop the final phantom semicolon from $*ORIG when done
TimToady er, the boilerplate was in viv, not Cursor.pmc orz 10:47
cognominal just curious about localisation, can it be done that way : 10:49
my Int enum day ('Dim','Lum','Mar','Mer','Jeu','Ven','Sam') where @*ENV<LC_ALL> ~~ /^fr/;
TimToady enum doesn't take 'where' currently
nor does normal expression code 10:50
literal and shouldn't that be %*ENV<LC_ALL> ?
moritz_ wayland76: remember where what is?
cognominal literal, yes, my bad. 10:51
TimToady my Int enum day do given @*ENV<LC_ALL> { when /^fr/ { ('Dim','Lum','Mar','Mer','Jeu','Ven','Sam') } }
wayland76 moritz_: Don't worry, he found it :) 10:52
cognominal Also I am learning scala and haskell, and I am not sure that pattern matching wise, Perl 6 is powerful enough... 10:54
dakkar cognominal: I'd keep internal values independent of presentation… it prevents lots of problems 10:55
cognominal What I like about scala is that xml has a composer.
dakkar, I suppose I would use that construct to "unparse" a enum according a locale. 10:56
dakkar oh. it might work…
cognominal I am not here to solve a specific problem but to map Perl 6 construct to whatever arbitrary (and possibly silly) use I can think :) 10:57
that's my way to learn.
Speaking about xml, I suppose it easy to determine if a "<" is an mere array composer or xml one. 10:58
wayland76 Where do I read about this XML composer? 10:59
cognominal I see that many haskell/scala pattern matching can be expressed in term of Perl 6 signature
wayland76 (or what does it do, if you prefer that?)
cognominal wayland, I will give you the pages of the scala spec... let me find 11:00
pugs_svn r27875 | lwall++ | [closure-parameters.t] missing semicolons
cognominal wayland, that Chapter 10 of www.scala-lang.org/docu/files/ScalaReference.pdf 11:01
xml composers also exist in the e4x javascript extension. 11:02
but one must use stuff like jsquery to pattern match DOM stuff.
xml in scala, that's 4 page of specs that pack a lot of power 11:04
wayland76 Is this sort of like XML heredocs?
Or am I completely missing something? 11:05
cognominal heredocs in Perl 6 generates strings... or am missing something? :) 11:06
wayland76 No, I've got the wrong end of the stick -- when you said "composer", I was assuming irrelevant stuff :)
Ok, let's try again -- are you saying this gives you easy pattern matching on XML? 11:07
cognominal maybe I got the wrong term
yes it gives that.
wayland76 Does it give us anything else?
cognominal but we can also see a xml node the Perl way, it is kind of a Signature a string, an array and a hash 11:08
wayland76, nope, but I think it is a lot.
wayland76 So you're saying it turns the XML into a perl object that can be accessed usefully as an object too 11:09
cognominal I am now speaking Perl 6 and not scala anymore.
wayland76 (yes, I'm mixing metaphors, sorry :) ) 11:10
Are you saying that if we had something like this Scala stuff in P6, it would generate useful P6 objects for each XML node?
cognominal well, I try to map general concepts like pattern matching in scala and haskell to what Perl 6 gives us. It happened that XML pattern matching in scala is very congruent with the rest of the langage. 11:11
yes, something like a Perl 6 signature. 11:12
wayland76 Are we talking about method signatures here? 11:13
cognominal if we don't special case special attributes like "id" and "class" that is an array.
11:13 molaf_x joined
wayland76 I'm confused :) 11:13
cognominal Well Signature seem to be a very ubiquitous type, I don't quite see the different between a Signature and a Capture. 11:14
11:14 synth joined
cognominal Well, my ideas are not very clear 11:14
wayland76 Well, I don't know enough about Signature to understand what you're saying, I think :) 11:15
cognominal "Ce qui se conçoit bien s'énonce clairement et les mots pour le dire viennent aisément" Boileau 11:16
11:16 synth left
wayland76 The one thing I'll mention is that masak and I have both been working on things that are related to accessing stuff in a Match object using XPath 11:16
(Btw, cognominal, thanks for trying to explain in English -- I'd never have coped in French :) ) 11:17
cognominal That would translate "What you think well can be said clearly and the word to say it come easily"
Just to say, a contrario, that my tought is muddy so my words are, and a lost is lost in translation :) 11:18
wayland76 I have enough French to be able to match some of the English up with the French, now that you've translated it :)
cognominal "lost in translation" A good movie btw... 11:19
11:20 donaldh left
wayland76 Haven't seen many movies (including that one) 11:20
11:20 donaldh joined 11:21 molaf_x left
cognominal It is not mentionned in the page I gave you but scala has \ and \\ that are the / and / equivalent of XPath 11:21
these are operators.
wayland76 Ok
cognominal I meant equvalent of / and //
wayland76 I'm looking at making a separate quoting context that lets you do XPath-like stuff on trees 11:22
cognominal: Yeah, I see what you mean
I considered doing the thing as XPath contexts, but in the end I decided quoted would be better :)
cognominal In fact the Chapter 10 is very terse, one cannot understanding the packed power if one does not know pattern matching in scala, 11:24
wayland76 Yeah, that's about what I thought while I was reading it :)
cognominal The two books about scala I have are more informative. 11:25
Maybe I can find you information in the scala wiki.
wayland76 An example would be best :) 11:26
Hey everyone, does anyone know how to get/set class attributes while in the .new() method? 11:27
moritz_ wayland76: you mean, in a custom new method? 11:28

moritz_ you pass them as named arguments to bless()

wayland76 After looking at it, it seems like it's like what I'm trying to achieve with my Tree stuff, that is, being able to pull stuff out of XML using XPath-like notation 11:54
cognominal probably
wayland76 Obviously I think it's a great idea, but when I tried to get it into core, it was rejected
But it can probably be done as a library
if it's a popular enough library, it will become ubiquitous :) 11:55
Maybe I can get it into Perl 6.1 :)
cognominal yes,, same for the xml composer, that a mere syntactical extension.
Matt-W There's no need for XML syntax support to be in core Perl
in 20 years when XML is long forgot, we'll be pleased it was just a module 11:56
wayland76 Matt-W: My Tree idea is more than just XML, though
It's supposed to be an abstract tree/graph type model that could model any tree-like structure, from XML to filesystems to LDAP to ... 11:57
:)
cognominal I suppose it could work on anything that is an attributed tree
wayland76 cognominal: That's my plan :)
cognominal I see that Perl 6 achieve all or (probably) part of it with signatures 11:58
Matt-W see that could potentially be amazing
takadonet morning all 11:59
cognominal wayland76, See =head2 Unpacking tree node parameters
in S06
wayland76 cognominal: Yeah, but I want to be able to do this on *any* kind of tree-like structure 12:00
Anyway, my plan is to code something up, and see what happens :)
cognominal well, signatures and context can do a lot of thing, I just want to be sure that pattern matching can be easily expressed in Perl 6. 12:02
And if it does, I understand Larry when refusing to add stuff that would be redundant.
On the other hand, we would need tutorials to map haskell/scala pattern matching to Perl 6 signature+context as pattern matchers. 12:03
wayland76 I don't think "redundant" is the word you want, but I see what you mean :) 12:04
Matt-W That sort of translation could be tricky, they're not the same thing.
Although you can get some of it with subsets
cognominal that's my point :)
12:06 fridim_ left
cognominal =head2 Argument list binding is also very particularly relevant 12:12
I need to understand all of S06 to answer my question 12:13
moritz_ if you write S06/Argument list binding/ the IRC logs will link to the correct section :-)
cognominal thx moritz_ 12:14

colomon What's the P6 syntax equivalent for the good old P5 while (<>)? I know I've seen it but I forget, and it's blocking me on paying work at the moment. :) 14:28
I tried "for $*IN.lines" but that doesn't seem to do it.
"for $*ARGFILES.lines" --> "Method 'lines' not found for invocant of class 'Failure'" 14:31
14:31 missingthepoint left
takadonet colomon: I believe it's $*IN.get 14:31
colomon takadonet: That doesn't seem to do anything. 14:32
Unless it tries to read all the lines first before starting the for? Let me try a smaller file... 14:34
No, that's still just sitting there.
takadonet colomon: are you trying to read a file or something from standard in? 14:35
colomon Read a file.
I've just rewritten the script to actually take a file name and open it. I was just hoping for the old Perl magic... 14:36
takadonet colomon: szabgab.com/talks/perl6/perl6-process-file.html Normally I would help you further but I have a meeting in a few 14:39
colomon Ack. Judging by the timing, it does try to read the entire file in before starting the for loop. With a 10 meg file and amazing Rakudo-speed, this may not be a practical solution. 14:40
takadonet One day it will
colomon Sure, but I need it today. Time to switch back to Perl 5... 14:41
takadonet++
PS That link is actually out of data... readline is no longer there. I believe "lines" (which is what I am using) is the current equivalent.

tann though i can't figure how to use exists, delete etc with hashes and arrays in p6 :) 19:35

doesn't seem like the spec settles on those things?
colomon I have this vague memory it is direct: %squares.exists($_) instead of %squares{$_}.exists
moritz_ it does, but it uses a syntax that isn't supported in Rakudo yet
it's %hash<foo>:exists 19:36
