s1n i want to beef up the recursion limit, i found an example in PIR, but i need to change this in :main 00:05
where would i find it, or it's equivalent in rakudo?

shinobi-cl hi..... im new to perl6 :) i love perl5 it does my work so smooth... 00:12
i have a quaestion,,, a simple one... i cant find it on the web :S what extension should i use for modules? pm or p6m or pm6 or p6 00:13
i want to port some code i did for reading some Doom wads info on perl5 00:14
s1n shinobi-cl: perl6-examples (on github) tends to use pl still, check other perl6 projects, maybe found on github 00:16
shinobi-cl thanks! :)
jnthn We're tending to still use .pm for modules. 00:26

just to define a prefix?

has this been implemented in rakudo yet though? 02:29

TimToady right, was thinking FIRST == START 15:24
masak ah.
TimToady but in any case it's still legal syntax, just bad semantics
masak so where is it caught?
TimToady where FIRST is attempting to look up its loop scope, and notices it doesn't have one, I imagine 15:25
masak oki
that sounds ALAP.
the compiler does nothing to alert to the probelm before?
s/probelm/problem/ 15:26
TimToady I didn't say that
masak :)
TimToady I just said the parsing doesn't catch it
masak ok.
TimToady a compiler also does semantic analysis
and in any case, is always allowed to complain about something it knows will blow up at run time 15:27
masak aye.
TimToady but STD is far from a full compiler
masak fair enough.
jnthn I suspect there will be a list of things that are meant to be complained about at runtime at latest, but compilers may blow up over earlier.
masak thinks that assignment to readonly variables should be on that list 15:28
jnthn I hope at some point Rakudo will be smart enough to do that at compile time.
I hope we can catch some obvious badly typed things then too.
TimToady it's often the optimizer that catches such errors

masak s1n: we're all going to have to adapt a little to Perl 6's syntax conventions. :) that's to be expected. 17:51
s1n: remember that you don't have to use parentheses at all in a for loop.
so the problem is negligible.

jnthn Aye, for 0..2 { ... } is the usual way to write it. :-) 17:54

azawawi s1n: perlcabal.org/syn/S04.html#line_1210 17:55
s1n the problem i have is with the whitespace changing the semantics of for
masak s1n: look. if you mash together the variables 'foo' and 'bar' in Java, it also changes the semantics. 17:56
this is no different.
17:56 _dh joined
s1n masak: but not many languages change 'foo ()' and 'foo()' 17:56
17:56 ejs joined
masak s1n: that's true. and I've heard this complaint before. I'm just not bothered by it myself. 17:57
s1n it will be an adoption issue
it will cause grief and frustration
masak people will have to learn to write 'for' without the parens.
s1n heh, that's optimistic 17:58
masak the rest of Perl 6 is worth the effort.
s1n it seems arbitrary to change that though
i guess i don't understand why it's that way? 17:59
literal I don't think so, people are already used to not needing parens in postfix form
so, in that way, Perl 6 is more consistent
s1n literal: i'm not saying no parens is bad
literal: i'm suggesting the whitespace changing it is very confusing 18:00
literal yeah, but what you get in return is you always know that foo() is a function call
s1n but 'foo ()' may or may not be 18:01
_dh sounds like something PHP would do to its users 18:02
literal no worse than Perl 5 in that regard :P
_dh :)
s1n sigh, am i the only one that thinks this is somehow wrong?
_dh s1n, no
s1n i _will always_ get that wrong when writing p6 code 18:03
literal you give yourself too little credit :) 18:05
s1n heh, no, because i don't write perl all day long, i switch back and forth with several other languages
which all make a clear distinction, 'for()' ~~ 'for ()' 18:06
literal then you should just drop the parens when writing Perl 6
masak yes, that's what I'm saying. 18:07
s1n again, i don't have a problem with using the non-parens version
masak s1n: apparently you do :) 18:08
s1n the whitespace changing the meaning between 'for ()' and 'for()' is odd
i actually like the non-parens version
literal it does so only because for isn't a function
that is, the loop construct is not a function
s1n why is a for function allowable then? 18:09
masak s1n: why shouldn't it?

pmichaud: the only really issue i have is the space, it kinda makes things confusing
_dh yea it is weird. 18:23
pmichaud as the synopsis indicate, we have to put some constraints somewhere so that we get flexibility elsewhere. whitespace is one of the (few) places where there's a constraint.
and the error messages will almost always indicate where the programmer made a boo-boo.
s1n could we not just make 'sub for' dwim?
or make 'sub for' invalid?
_dh i hope there's not too many other weird changes like this. as it might make the lang unpopular. and it's already got enough competition as it is 18:24
pmichaud why make 'sub for' invalid? That sounds like an unnecessary limitation.
s1n hey okay, it's not my language
i'm just suggesting people may find that a sore spot
pmichaud afaict, people who actually write much p6 code haven't found it a sore spot.
s1n the first module i'm going to write though will fix that 18:25

jnthn It could always be both. <grin>
pmichaud s1n: in that case you're calling 'foo' as a listop.
s1n sub for {}; for (0..1);
listop? 18:30
pmichaud in that case you're likely to get a syntax error.
because the 'for' statement expects a block.
s1n pmichaud: so postfix for loops aren't valid?
std: say $_ for 0..2;
p6eval std 24867: OUTPUT«00:05 86m␤»
pmichaud in that case 'for' is a statement_loop modifier. 18:31
it's clearly not a function call.
s1n std: sub for {}; for (0..1);
p6eval std 24867: OUTPUT«00:05 85m␤»
s1n no syntax error?
pmichaud okay, I'm guessing std doesn't generate an error but perhaps should.
keep in mind that std isn't complete.
s1n i'm just trying to make sense of this 18:32
to me, with my pea-sized brain and all, this seems confusing
pmichaud just be sure to have a space after 'for', 'if', 'while', etc. and everything pretty much does what you want.
s1n maybe not to everyone else, but that's why i loathe python
pmichaud unless you _want_ to write functions named 'for', 'if', 'while', etc., in which case you get what you ask for
s1n pmichaud: are module's supported yet? can i write my own and import it? 18:33
pmichaud the nice thing about the p6 version is that the parens aren't required.
so it's not like we're adding keystrokes. Less, if one considers that ( and ) are actually two keypresses each.

_dh if the change helps improve perl such as its executation time then i'm all for such changes, but if it was done for the sole purpose of somebody just thinking 'hey lets change this, cause its cooler!' then i'm afraid perl is going in the wrong direction 18:36
pmichaud it improves our ability to extend Perl. 18:39
s1n pmichaud: how?
pmichaud by giving better control over parsing and distinguishing statements from subroutines. 18:40
moritz_ s1n: it bascially allows you to add new keywords without fearing to break subs of the same name
ovid Well, as of the last compile, "my $line = =$*IN;" no longer throws an error. I just silently does nothing (that I can see). 18:41
pmichaud it should be waiting for input from stdin.

moritz_ that only works if we buid a basic computer algebra system into Perl 6 19:26

moritz_ it does terminate on the closing atom, if it backtracks

pmichaud (and FAILGOAL is what throws the exception)

Unintended consequences of something else, I'd guess
jnthn suspects that (a) some code was pulled out in rvar and not re-instanted and (b) we didn't have a test for this so it went unnoticed.
rvar removed a bunch of stuff to make refactoring easier and then added it back in.
I think I know exactly what we've lost.
Matt-W hurrah
jnthn Please file a ticket, I'll try and sort that out tomorrow. 19:58
jnthn needs to do _lots_ of work on roles in the next few weeks.
Matt-W right-o
jnthn If it's what I think it is, it'll be an easyish fix.
jnthn afk for a bit 19:59
Matt-W ticket filed 20:02
moritz_ Matt-W++ 20:04
Matt-W Bah
it'd be better if I could have a quarter of a clue how to actually fix things
filing bugs is easy
moritz_ Matt-W: I know, but bug filing and writing tests cases is also important 20:05
Matt-W: speakiing of which, can you please turn your example into a test suite?
s/suite//
Matt-W umm
I can try
moritz_ t/spec/S12-role/composition.t seems to be a good place 20:06
Matt-W where does that live
moritz_ rakudo: my sub foo { "bar" }; say foo();
p6eval rakudo 35423: OUTPUT«bar␤»
moritz_ Matt-W: in the pugs repository
Matt-W ahah
i shall grab that then
moritz_ and rakudo imports that into t/spec if you say 'make spectest' 20:07
Matt-W aaaah
that's good
keeps the language tests in one place
moritz_ right
Matt-W pugscode.org is really broken 20:08
moritz_ Matt-W: the index site lives at docs/feather/index.html in the pugs repo. Feel free to fix whatever you want 20:09
Matt-W I don't have commit access
moritz_ that can be changed 20:10
tell me your email address (in a query if you fear spam) and desired nickname
Matt-W Perhaps it's time it was
moritz_ and you'll get a commit bit in two to five minutes ;-)
Matt-W heh
moritz_ in the pugs repo we're fairly liberal with handling commit bits 20:11
Matt-W: email send. It's customary to add yourself to AUTHORS in the first commit, to test the commit bit 20:12
20:13 ovid left
moritz_ to all new pugs committers: you can also invite other people that want a commit bit, go to commitbit.pugscode.org/admin/project/Pugs/people to do that 20:15
pugs_svn r24874 | mattw++ | Adding myself to AUTHORS to test commit bit
Matt-W well that seems to hav eworked 20:16

r24877 | mattw++ | test for RT #62200: classes overriding methods from roles 20:24
Matt-W moritz_: could you check that please
moritz_ Matt-W: sure, just a sec
Matt-W: when you add a test, you should adjust the plan() statement at the begin of the file, which tells us how many tests we want to run 20:25
Matt-W doh
I should know that
moritz_ Matt-W: and since rakudo currently barfs on it, you should also surround the new section with #?rakudo skip 'RT #62200'\n{ ... } 20:26
Matt-W so change plan 8 to plan 9 20:27
and put that block around the new bit
moritz_ right
pugs_svn r24878 | mattw++ | Fixes from moritz++ to do the test properly 20:28
s1n hmph, i can't seem to remember my pugscode password 20:29
i checked .subversion/auth/svn.simple and that didn't work on the commitbit.pugscode.org login 20:30
moritz_ s1n: did you try your email address as user name?
s1n moritz_: doh, i apparently can't read heh 20:31
pugs_svn r24879 | moritz++ | [t/spec] indent lines in composition.t to not confuse the fudge script 20:32
Matt-W oh I have to indent as well
s1n moritz_: pugscode is under MIT license and not artistic?
Matt-W for some reason I assumed otherwise
moritz_ Matt-W: that's a current limitation of the fudge script which I always forget :( 20:33
s1n: what makes you think so? does it say somewhere?
s1n admin page 20:34
overview has license selected as MIT
moritz_ that's certainly not right
README contains some license informations 20:35
s1n oh, okay whatever 20:36
20:38 jan_ left
Matt-W okay 20:41
now svn has decided to do nothing
moritz_ it works here, albeit very slow 20:42
Matt-W it seems to have decided that I didn't update the file I updated
moritz_ what does 'svn status' say about it?
Matt-W nothing at all 20:43
20:43 ovid joined
moritz_ that means it's unchanged 20:43
Matt-W hmm it does seem to be 20:44
that means the version in svn had already been fixed
but the one on the web isn't that version
moritz_ which file and version are you talking about?
Matt-W docs/feather/pugscode.org/index.html 20:45
ovid I was looking at pugs/examples/cookbook/ and it seems like the files in 01strings/ are named after the 1st edition Cookbook, but the README (which I wrote, to be honest) states the we're working from the 2nd edition and the files in cookbook/ are definitely named after 2nd edition chapters. Is there a misunderstanding?
Matt-W gosh, it was fixed in september, says svn log
in r22212 20:46
and r22211
moritz_ ovid: feel free to make it consistent in the way you prefer it
Matt-W: so basically the web page isn't up-to-date? 20:47
ovid @moritz_ Thanks.
lambdabot Unknown command, try @list
moritz_ ah, it doesn't use the file from svn, bug from audreyt's svn checkout 20:48
and since she hasn't developed pugs in a while, here working copy is quite out of date 20:49
I'll try to fix that
and that svn checkout is actually a svk copy, and svk isn't installed 20:51
20:52 jan_ joined, spx2 left

ovid Should the examples in the cookbook run under rakudo? I think they should target Perl 6, but they're in the Pugs repository. 21:24
moritz_ that's the choice of whoever decides to maintain them 21:27
ovid OK. I see they don't run, regardless, so they should probably be rewritten. 21:28
moritz_ first of all they use perl 5 style POD 21:29
that's probably the biggest obstable
erm, obstacle
ovid Yeah, I was noticing that. I don't know Perl 6 POD, but I could probably fix 'em up.
moritz_ just enclose it in =begin pod\n...\n=end pod
rakudo will ignore everything between that 21:30
21:31 ejs left
ovid OK 21:31
moritz_ uhm, these files seem to be 100% POD anyway, right? 21:32

mberends please see if you can reach my HTTP::Daemon server at autoexec.demon.nl:8888/ I need to verify that I poked the correct hole in my NAT router 22:14

ovid Trying to learn pir and can't figure out why that doesn't compile. 22:38
moritz_ ovid: maybe because tmps is a PMC, not a String? 22:43
ovid I'll try that
moritz_ $S0 = tmps 22:44
curchar = sustr $S0, -1
22:45 eternaleye_ joined
moritz_ ovid: it seems that the is_cclass opcode is better for testing if something is a whitespace or not 22:45
languages/perl6/src/parser/quote_expression.pir contains ``$I0 = is_cclass .CCLASS_WHITESPACE, target, pos'' 22:47
ovid How do I tell the length of a string? I get "unexpected PARROT_OP ('length')" if I call "length tmps"
I'll make the whitespace switch now.
22:47 icwiener joined
moritz_ $S0 = "abc" $I0 = length $S0 print $I0 print "\n" 22:48
outputs 3 for me
moritz_ keeps adding ;'s to the lines in PIR 22:50
thankfully that generates very readable error messages
ovid Bah. is_cclass doesn't get recognized. I tried including cclass.pasm, but no love. This is too finicky for me. I'll need to read the docs more :( 22:52
Ah, I at least got 'length' to apparently work :) 22:53
22:57 cspencer joined
moritz_ ovid: is_cclass works for me if I substitute .CCLASS_WHITESPACE by its magic number, 32 22:58
ovid OK, I'll give that a try after more futzing around. 22:59
It currently takes me about a minute to recompile each time, so it's slow going :)

jnthn wasn't aware state variables were implemented...
moritz_ neither was I
but before the rvar2 merge state variables complained loudly at compile time 23:18
jnthn rakudo: sub foo { state $x = 1; $x++; say $x; }; foo(); foo();
moritz_ now they just seem to do the same thing as my
p6eval rakudo 35425: OUTPUT«2␤2␤»
jnthn That's probably because we're parsing the state keyword, but not doing anything more than we do for "my".
moritz_ and when I look at 'method scope_declarator' it seems that any unknown scope declarator is handled just as 'my' 23:19
I might have unfudged some tests that relied on 'state $x' not being a fatal error 23:20
ovid Wow. I finally got trim working in pir, but cutting and pasting it into src/builtins/any-str.pir doesn't work (though I fixed the sub declaration). I'll write and email to the list to figure out what's up. 23:26
moritz_ one of the differences is that in any-str.pir you'll probably get a Perl6Str object, not a string thing 23:34
so you might have to cast into a $S register first
anyway, bed time for me
ciao
ovid OK. See you. Thanks for your help. 23:35
