do you recomend me to use perl? 02:42

sosey dukeleto: i'm enjoy writting c code, so i think i can enjoy writting perl code 02:46
dukeleto sosey: perhaps :)
snarkyboojum sosey: writing C and Perl 6 is very different, but most people in here would at least say "Give it a try" :D
dukeleto sosey: what kind of code do you want to hack on? what interests you? It is hard for anybody to help you if we don't know what you are trying to do. 02:47

skangas Is there something like //= but for regular expressions? 03:18
I would like to do "$foo =~ /bar/" without having to prefix it with "defined $foo &&"
Otherwise if $foo is undefined, I get "Use of uninitialized value in pattern match" 03:19
Oh crap, wrong window, I thought this was #perl. Sorry :-( 03:20
colomon skangas: I was trying to figure out how to answer the question in Perl 6. :)
skangas colomon: That would be interesting, too, albeit not directly relevant to what I am doing right now. ;-) 03:21
colomon mind you, I don't know that I have a better answer than ($foo // "") ~~ /bar/
which still seems kind of awkward, IMO.
flussence_ couldn't it just do "class Regex { multi ACCEPTS(Any) { Bool::False } }", or would that break other things? 03:27

sorear [Coke]: THere's a --keep-exit-code or similar option that Rakudo uses 05:16
pmichaud: Doesn't PIRATE already implement #4? 05:18
pmichaud sorear: yes, apparently it does, although I'd like to see that declared "official" somehow for Parrot (either official tool or official approach for achieving that result) 05:19
[Coke] sorear: yup, danke. 05:20
hey, can we close 63584 with "well, don't DO that, then?" 05:21
sorear [Coke]: I'd rather we didn't. 05:22
One of my favorite things about the Perl5 toolchain is that it's very good about handling >1 perl in the $PATH
or even outside $PATH 05:23
[Coke] it's not that there's more than one perl in the path, it's that he re-arranged his path.
sorear I can install software using /opt/perl-5.11-debug/bin/perl $(which cpanm) ... and it all just works, even if the modules need to build XS and ...
[Coke] hurm. nevermind.

[Coke] sorear: I misread. he used /foo/to/bar/perl, but first-in-path was being picked for other things. 05:32
I'll put in a poisoned perl and see if anything breaks.
*facepalm* 05:36
if you build parrot with "perl", that's what's passed along to Rakudo's build system as the perl to use. not /derived/path/to/perl, just "perl" 05:37
so if you build parrot, change your path, you're going to get a different perl. (or, if you run rakudo's configure.pl and change your path, the build will use a different perl.) 05:38
... not sure if this is worth fixing.

pmichaud if adding BigInt doesn't slow down the existing parts of Rakudo, I have absolutely no problem with it. 19:09
colomon oh. 19:10
pmichaud I don't mind if BigInt is slow, I just mind if it slows down what we already have. :)
colomon understood.
well, I'll keep that in mind, and talk with more about it in a few days, then. 19:11
pmichaud sounds great
PerlJam What does python use for arbitrary precission arithmetic? The python is *fast*
jnthn We already have the checks in place, iirc. 19:12
Promoting to BigInt where we today promote to Num is likely not too big a deal.
colomon jnthn: not really. we do calculations in Num, and then switch back to Int if they fit.
jnthn Oh.
PerlJam ah, gmp of course
colomon that's not at all the same as doing them in proper Int form internally. 19:13
jnthn I'm still not really too taken with those being the same type.
But I guess people can use int if they want speed.
Trouble is that then we force people into type annotations. 19:14
colomon though I guess we could do what we do now, and then just redo the calculation if the result would overflow an int.
pmichaud I think the Perl 6 vision was that Int would have two reprs behind it (one fast, one big) and would internally switch as needed
not that there'd be a single BigInt repr
colomon Ack, it needs clever scheme, and right now I should be worrying about $work.

...that could be, er, evil. :)
pmichaud basically, Int is a type wrapper around multiple "integer" types
perhaps like Numeric is a type wrapper around Int + Rat + Num
jnthn Yes, but "type wrapper" is clearly defined there. Numeric is a role and the others do it. :) 19:16
That could be a viable solution here though, perhaps.
pmichaud Right, I mean it in a handwavy sort of sense. 19:17

Yes, the trouble is that the hands have never not waved on this issue yet. ;)

colomon heredocs are awesome, and p6 heredocs are supposed to be even better, but they're not supported in Rakudo yet. 20:14
moritz_ I think niecza does them so 20:15

colomon You know, I thought the whitespace magic was p6's killer feature. (back in 2003, that is. ;)
20:24 y3llow left, pothos left, fhelmberger left
PerlJam I thought p6 had two killer features: grammars and a nice OOP system. The first one is still a killer feature but the second one seems to have had enough time to leak out into the world 20:25
flussence_ (I've "almost" got .indent done btw, "just" need to figure out how to handle \t properly :)

masak flussence_: cool! that's great news. 20:26
if you feel the need to air ideas for how to implement that (or how to make S32/Str clearer), we're here for you.
PerlJam flussence_: What's the problem with \t exactly? And how can we help? :)
masak the problem is that there's a complicated invariant to be upheld between a \t and a certain number of spaces. 20:27
"\t".indent(4) eq "\t ", but "\t".indent(8) eq "\t\t" 20:28
and outdenting is tricky, too.
PerlJam whoa, is is a requirement that .indent generate tabs? 20:29
flussence_ I look a look at the Text::Tabs takadonet++ wrote, it's a bit verbose but I get the general idea of how to do it
pmichaud PerlJam: if tabs are present, I think .indent is supposed to preserve/extend them 20:30
takadonet flussence_: I never did finish it and I was simply doing line by line converting from the p5 version 20:31
i'm happy someone else is finishing it
PerlJam preservation I get, but extending I'm not so sure about. 20:32
And I just checked my copy of the spec and it only says "C<$steps> number of spaces have been added to each line"
though, I guess "consistent with leading whitespace" could be interpretted to mean "add tabs if the string starts with tab" 20:33
okay, never mind me :) 20:34
PerlJam wonders about other leading whitespace though 20:35
if the line starts with a unicode non-breaking space, does that mean that .indent will add NBSs rather than space characters? 20:36
20:37 cafesofie left 20:39 kst left
pmichaud in the past, I've found .indent to conceptually be very much a dwimmy sort of construct 20:41
so I'd think "yes"
i.e., it's past descriptions imply that the dwimminess knob is turned up fairly high
PerlJam I guess the requirement that they all be the same is a concession to implementors for making that easy :) 20:43
otherwise you'd have to have crazy logic for all of en.wikipedia.org/wiki/Space_(punctu...in_Unicode
20:43 kst joined
pmichaud "Perl exists to torment the implementors on behalf of the users." 20:44
or something like that.
PerlJam flussence_: where is your implementation of .indent? 20:46

PerlJam flussence_: gist.github.com/804840 I updated a comment and added a case for indenting where the string starts with a sequence consisting only of some other space character. No tests though. 21:23
flussence_ wait, is that default{} inside when{} correct? 21:28
21:29 Mowah left, plobsing left
masak flussence_: you can put a default {} anywhere. 21:31
flussence_ huh, I never knew that!
masak 'given' and 'when/default' are completely decoupled.
moritz_ you can also do for @list { when ... { }; default { } } 21:32
masak 'given' is just 'OK, we'll use this value as $_' (or whatever signature you pass into the pblick)
PerlJam flussence_: actually that was a cut-n-paste error :)
masak 'when' is just 'smartmatch $_ against this expression'
as moritz_ points out, 'given' is a kind of loop. 21:33
(that only iterates once)
PerlJam flussence_: fixed. But I'm glad you learned something from my error :)

sorear flussence_: I hear you've thought a lot about whitesace in here docs. 23:50
flussence_ as I understand the spec for heredocs, the whitespace rule looks identical to .indent(*) 23:53
sorear I've heard some people say that dedenting is sensitive to how the string is built 23:54
e.g. in my $foo = ' bar' ; say qq:to(pie)\n$foo\n pie 23:55
flussence_ hm, I see 23:57
IMO the whitespace trimming should happen before any interpolation 23:59
I can see how it might complicate things either way, though
sorear how do you suggest to accomplish that?
