ovid Whee! I've now submitted a patch for adding the .trim method: use.perl.org/~Ovid/journal/38261 That was frustrating and fun at the same time. 00:21
jnthn ovid: It tends to get more fun and less frustrating as time passes. :-)
ovid I hope so :)
OK, time for bed. Head hurt. Need pillow. 00:22

moritz_ currently perl6.vim is too slow for real-world usage 09:48
I think we should sacrifice exactness for more speed 09:49
any objections? (espeically from literal)
literal yeah, I was intending to do that 09:50
basically, have some perl6_extended_foo options when you want slow, but exact highlighting
moritz_ +1 09:51
literal but use something fast which covers only the common cases, by default
Matt-W speed would be nice 09:53

moritz_ as a method in Str, I wouldn't object 13:22
masak moritz_: and 'is export', yes. I saw that some adaptions needed to be made from ovid's pod doc suggestion. 13:23
also the named params, if we decide to throw those in.
.perl only exists in method form, right? there's no 'perl($var)'? 13:37

moritz_ and as usual, pugs permits nearly everything :-)
Matt-W In Perl 6, is there any difference between (1, 2, 3) and [1, 2, 3]? 13:41
moritz_ yes 13:42
the former will flatten in list context
perl6: my @a = 1, (2, 3, 4), [5, 6, 7]; say @a.perl 13:43

..elf 24886: OUTPUT«[1,2,3,4,[5,6,7]]␤»
moritz_ note that rakudo and elf say the same thing, elf just omits the whitespaces
masak Matt-W: (1,2,3) is a List, [1,2,3] is an Array. 13:49
Matt-W aaaah
masak moritz_: that's a bug in Elf, I'd say.
moritz_ yet a List also .perl'ifies ilke an array
masak: why is it a bug?
masak Matt-W: List objects are immutable, Arrays are mutable. 13:50
Matt-W so [1, 2, 3] gives you a single object, which can then be stuck into a list as an element
rather like an anonymous array reference in perl 5, in some situations
masak moritz_: um, now that I think about it, it isn't...
Matt-W how convenient :)
masak moritz_: I was confusing .perl with stringification.
moritz_ neither S02 nor S29 define a format for the output
masak moritz_: you're right.
should they?
I mean, is there a good reason to? 13:51
moritz_ not really
for things as complicated as subroutines I'm sure the implementations will differ
masak maybe warn people not to depend on implementation specifics in .perl methods? 13:52
13:52 maerzhase joined
moritz_ that's a topic for user-level documentation, not design documents 13:52
Matt-W I'd have thought it was acceptable to provide any alternative that parses back to the original structure 13:53
moritz_ aye, that's the current spec
masak moritz_: I see S29 as user-level documentation. 13:54
I think that's why I care about it the way I do.
moritz_ masak: compare it to perlfunc in verbosity, and you'll see that it's not nearly there 13:55
masak I know. :/ 13:56
13:56 jimmy_ joined
masak I prefer to compare it to Ruby's ri. 13:56

p6eval rakudo 35436: OUTPUT«Lexical 'self' not found␤current instr.: '_block14' pc 51 (EVAL_15:38)␤»
moritz_ I think that's something we should discuss with @Larry when we get to it
masak 你好, jimmy_ 13:58
moritz_ but I don't see anybody complaining about too much user-level documentation in any of the synopsis documents
so that topic can wait 13:59
Matt-W There isn't any user-level documentation in most of the synopses :)
jimmy_ is going to game. 14:00
moritz_ there are occasional "to achieve $perl5_feature do $this instead" comments
Matt-W it's not really a comprehensive attempt at user-level documentation 14:02
14:02 riffraff joined
Matt-W I've made a couple of abortive attempts at a Perl 6 tutorial thingy 14:02
masak I think having a good REPL and ri/perldoc-like thing ready for Rakudo 1.0 would be a worthwhile goal.
Matt-W yes
masak sometimes I think Envy should be one of the Perl virtues.
look at what Ruby has :) 14:03
poignantguide.net/ruby/expansion-pak-1.html
Matt-W there needs to be Perl 6 for Perl 5 Hackers too
masak aye, definitely.
if you want the O'Reilly contract, start writing the manuscript now.
Matt-W I did have a chapter published once in someone else's book 14:04
moritz_ Matt-W: Perl6::Perl6::Differences and my 5-to-6 blog both aim in that direction
Matt-W moritz_: excellent
I was sure I wasn't the only person thinking about it
moritz_ speaking if writing... if all goes well I'll write an article about Perl 6 Regexes for one of Germanies most reputable IT magazines 14:05
Matt-W Excellent 14:06
I shall have to brush up on my German
moritz_ s/if/of/
sadly I have to assign them the copyright, so I can't publish it freely 14:07
masak moritz_++
I guess there's not much room for negotiation there.
Matt-W You just have to live with that sometimes 14:08
At least you'll be getting the word out
moritz_ and on the bright side it'll also bring me some money
not very much, but perhaps half of my tuition fees for the semester :-) 14:09
Matt-W That's not to be scoffed at
The only thing I've made serious headway on with regard to Perl 6 documentation is a set of slides loosely based on some Perl 5 ones I did for work
but about Perl 6 instead
the trouble is I keep being tempted to compare to Perl 5, whereas I just want to present it as its own thing 14:10
donaldh moritz_: where does your 5 to 6 blog reside?
moritz_ donaldh: perlgeek.de/blog-en/perl-5-to-6/
Matt-W Also I need to do more coding in Perl 6 to get the depth of knowledge to write the thing accurately
moritz_ it's not been very active lately
donaldh some useful examples all the same 14:12
14:12 ejs left
moritz_ they are not tailored to work with present day rakudo 14:12
more to show off, and generate some interest
Matt-W It's good stuff though 14:14
moritz_ thanks 14:16
mdxi seconded. very good stuff :) 14:18
masak thirded. kudos.
moritz_ OH NOEZ, I'VE BEEN THIRDED :-)
masak were the traffic higher here today, you'd surely have been fourthed and fifthed :P 14:20
moritz_ OMG
people use quite a lot RSS these days 14:21
masak brave new world.
moritz_ the rss feed got 90k hits, the most popular HTML page (the link above) has about 1/10 hits
even though many people use google reader, which caches the feed internally 14:22
avar moritz_: does the perlgeek.de/blog-en/ rss feed cover perl 6 and perl6-to-5 ? 14:23
mm, 5-to-6
donaldh moritz_++
avar evidently so 14:25
14:26 jimmy_ left
avar moritz_: your rss needs a date for each entry 14:26
moritz_ avar: perlgeek.de/blog-en/index.rss covers all the blog, including non-perl6-stuff
avar saw 14:27
moritz_ avar: aye, but that freakin' blog system isn't easy :(
avar rakudo.de/ <- has the test suite really grown this much since last year or is it only t/spec ? 14:28
moritz_ avar: mostly t/spec has grown 14:29

moritz_ for real world code .isa (inheritance) or ~~ (type conformance) is usally enough 22:50
jnthn ovid: When calling methods on the metaclass, you also need to pass along the invocant.
rakudo: my $foo = "asdf";say $foo.HOW.isa($foo, "Exception")
p6eval rakudo 35458: OUTPUT«0␤»
jnthn But there's a special syntax for that. 22:51

jnthn Which calls it on HOW and passes $foo along as well.

moritz_ it can be really annoying that on German keyboards ~ and Enter are too close
sometimes I want to write 'rm *~' to get rid of the vim backup files

moritz_ and you know what happens when I hti the Enter key instead of ~ ;-) 23:09
eric256 thank goodnees your using revision control ;)
moritz_ not for my home dir :/ 23:10
I probably should :)
rakudo_svn r35459 | moritz++ | [rakudo] implement Str.trim, patch courtesy by Ovid++
ovid Yay :) My first "real" Perl 6 patch. I'm so proud :)
jnthn ovid++ # nice work! 23:11
23:11 |jedai| left
jnthn S29 needs a patching too, to add trim, if that didn't already happen. :-) 23:11
jnthn should really get around to working on S14 at some point soonish too. 23:12
ovid Thanks. It wasn't an impressive task, but it was a nice introduction to pir.
eric256 looks like try creates a Failure not an exception? but the Failure pir has a !exception method...whats the ! mean in parrot?
23:12 [particle]1 joined
jnthn We use ! for "private" usually. eric256: The problem is that somehow the Parrot Exception doesn't get given various methods it would normally inherit from Object, though, it seems. 23:13
23:13 |jedai| joined
jnthn As in, Parrot's Exception class and Rakudo's Object class. So much mapping "fun"! 23:14
ovid Known? Method 'perl' not found for invocant of class 'Iterator' 23:15
eric256 well the !exception method in Failure.pir creatse an Exception object if it doesn't already have an exception... i think pir might hurt my head at this point
moritz_ ovid: not to me
ovid Sigh. Another one to reduce to a minimal test case :)
moritz_ ovid: masak would be so proud ;-)
ovid Now to figure out what the goldbach conjecture is doing :) 23:16
Who is masak?
moritz_ our chief bug reporter
and developer of a Perl 6 wiki engine
jnthn Probably half of the RT queue is his reports. :-) masak++ 23:17
(If not more...)
moritz_ half of the RT tickets in the perl6 queue are his, I think
ovid Oops! I should pay more attention.

ovid Larry says that @array.trim should die with 'no such method' because of @array >> .=trim. How would I implement that? 23:25
[particle]1 check that the param does Scalar? 23:26
wait, won't the sig already check for that? 23:27
ovid Is it sub 'trim' :method :multi('Str')?
I have sub 'trim' :method :multi(_)
[particle]1 likely, yes
ovid I'll try that. 23:28
[particle]1 it might be (['Str'])
23:28 aindilis left
[particle]1 that bit of syntax has recently been discussed, not sure what's current 23:28
23:28 aindilis joined 23:29 [particle] left, maerzhase left
jnthn Does this mean that maybe it's just a method on Str, not on Any? 23:31
ovid It looks like "sub 'trim' :method :multi('Str')" works just fine.
jnth: Yeah, that's what it would mean. Hmm ... I'm not sure if that's what would be intended. 23:34
I also asked "Won't that fail with 'No such method' on an array of hashes? Or are hyperops applied recursively?" 23:36
[particle]1 you can do >> .keys.trim 23:37
hrmm, maybe it'd be @array>>.values.keys.trim; 23:38
if you want to trim the keys of the hash
>> is probably going to iterate over @array.values, so it's probably just .keys.trim 23:39
jnthn I think it's recursively.
I think hyperops also work over hashes.
I didn't implement that bit though.
[particle]1 i guess i have some re-reading to do :)
jnthn I looked at the hashes bit and thought...OK, another day. :-) 23:40
eric256 wouldn't that be @array>>.key.trim ? i was thinking >> would be like .key.trim for @array (but that might not be the case) 23:41
ovid Wow! It's astonishing how many bugs my new Test.pm has exposed! :(
[particle]1 what is Pair.trim going to do? that's the question. 23:42
