synopsebot Link: rt.perl.org/rt3//Public/Bug/Displa...?id=123215
vti hi, i am trying to use smth like __DATA__, which i understand is supposed to be in $=data, but it doesn't seem to work now (Variable '$=data' is not declared), so i just tried pod blocks, but they are not verbatim, i have tried =begin input, still not verbatim, the only working solution is to use =begin code, but i don't like it, since it's not code, any advice? using rakudo 2014.09, thanks 10:13
masak hm, good question. 10:14
there ought to be a nice such example somewhere that we could link people to. 10:15
vti i have cloned ALL perl6 modules and couldn't find an example
and google also didn't help, this channel is the last resort :)
timotimo yeah, the data section thingie is not yet implemented ;( 10:19
vti that's ok, i was just thinking there was an alternative, but i will probably stick with =begin code for now 10:21
timotimo a heredoc should be good, no? 10:22
you know heredocs can be indented in perl6?

nine .tell raiph: thanks. Of course there'll always be edge cases that need some workarounds. But from my practice using Perl 5's Inline::Python I can say, that there are always workarounds and most code does just fine 11:14
yoleaux nine: What kind of a name is "raiph:"?!
nine .tell raiph[3~: thanks. Of course there'll always be edge cases that need some workarounds. But from my practice using Perl 5's Inline::Python I can say, that there are always workarounds and most code does just fine

nine ???
.tell raiph thanks. Of course there'll always be edge cases that need some workarounds. But from my practice using Perl 5's Inline::Python I can say, that there are always workarounds and most code does just fine
yoleaux nine: I'll pass your message to raiph.
timotimo jnthn: what do i need to do to make sure an optimization in rakudo's optimizer optimizes all branches of a want? or should i just appreciate the fact that i can see a before/after optimized tree in the two branches of a Want? %) 11:17
11:18 denis_boyun_ left
jnthn timotimo: The latter; when the optimizer doesn't walk both, it's 'cus it has a good idea that they mostly share the tree. 11:18
timotimo: As is the case with sink
timotimo: We could a HUGE win by not walking both.
*got a
bbi10 11:19
timotimo in that case i should perhaps modify the nodes in-place rather than replacing parts of it 11:20
or perhaps just not care? :\ 11:25
vendethiel There's a lot of backlog these days! That's good, but a bit bad as well 11:34
jnthn timotimo: "Not care" may be a better option that it sounds
timotimo sorry, i'll shut up, vendethiel! :P 11:35
jnthn timotimo: If we're lucky, then there's always some QAST::Stmt or so above the node that is shared
vendethiel timotimo, it's fine, I don't read your lines anyway :)
nine Indentable heredocs...you just _have_ to love this language :) 11:36
jnthn nine: With regard to that feature - if you're implementing it, you love it much less :D 11:37
vendethiel indentablewhat?
nine jnthn: I guess that's true for many of Perl 6's features.
vendethiel just also read that in the backlog :)
11:38 psch joined
nine I'm so glad I backlogged...this is exactly what I need with all that inlined Python code. with Python being so picky about indentation... 11:38
psch ho #perl6 \o 11:39
vendethiel nine: I backlogged, but saw no such example
smls jnthn: Are heredocs de-dented at compile time? 11:40
psch FROGGS: testers.perl6.org is down, from the looks of it
jnthn smls: I originally had it as "yes if they're constant, no if you interpolate"
psch FROGGS: does submitting depend on the site being reachable?
jnthn smls: I think that now the interpolating case does something more interesting. 11:41
smls Why would you want spaces from interpolated variables to affect indentation?
timotimo they are dedented at compile time 11:42
that means spaces from interpolated stuff don't get cut off
jnthn smls: I dunno, frankly I just *would not write code* that interpolates a multi-line string an a darn heredoc! :P
*in a
smls I'd just de-dent before interpolating 11:43
jnthn But apparently folks changed it so it does what folks who like to write such code get what they expect. :)
timotimo before the dedentation was turned compile-time, a "tried to dedent but not enough space available" error was very common to get here and there
nine jnthn: simple example where it does make sense. A bog standard mailer for a contact form on a website. 11:44
Message body as heredoc, variables interpolated and multi line values quite common 11:45
jnthn hmm
I guess.
FROGGS psch: yes
jnthn hasn't written a form mailer for 10+ years :)
But yeah, I can see that...

you want the message to be indented? 11:55
because it's multiline?
11:56 sqirrel__ left 11:58 jack_rabbit joined 12:01 EXIXT is now known as exixt
nine timotimo: no problem. It's just a use case where I think it makes sense to interpolate a multi line string into a heredoc. And where it's great that Perl 6 dedents there heredoc for me before interpolating 12:01
timotimo oh 12:02
i thought you were arguing *against* the current behavior %)

timotimo (compared to the 2014.11 release, that is)
jnthn Not bad.
timotimo i'll take it
next step would be to get rid of the defor if it's not needed
sounds like something spesh could do well
jnthn May already be able to... 12:50
May need to learn about .DEFINITE
timotimo it's not in there yet
oh, it's not equivalent to "isconcrete", eh?
jnthn I think isconcrete is already spesh'
timotimo yes
jnthn Right, it gives a p6bool instead iirc
But that is just adding facts to say it's a constant value 12:51
And I guess the conditional spesh then will see it's a constant boolean value and do the right thing...
timotimo you're suggesting to call the .DEFINITE method at spesh-time? 12:52
jnthn It's not a method. 12:53
That's why it's uppercase.
arnsholt jnthn: Aside from putting in a QAST::Var(:decl), are there any other ways to tell a lexpad that it's OK to bind to a symbol?

jnthn colomon: But maybe somebody in Europe (lizmat?) could offer me one... 12:55
colomon: Which'd be more responsive :)
But I'll take what I can get :)
colomon jnthn: true.
timotimo jnthn: but implementing // simply as QAST::Op( :op('defor'), :name('&infix:<//>') ) should be correct?
jnthn timotimo: Oh, right, I see what you mean... 12:56
timotimo: And yes.
timotimo ah, .DEFINITE is just p6definite
jnthn Right.
But I don't think // uses it
timotimo that seems to be the case, yes
so defor should be easier to do
jnthn Guess so
timotimo oh 12:57
defor gets compiled down to an isconcrete + if_i in QASTCompilerMAST
so nothing more to do there
jnthn Check that Rakudo doesn't override it. 12:58
timotimo 'k
jnthn But yeah, I think nothing more to do.
timotimo oh 12:59
rakudo does "callmethod defined"

Does it guard it with a isconcrete first?

colomon did have a hand in writing the match code about two major versions of rakudo ago. doesn't have much in common with the current code... 14:24
masak oh, I found what might be a reason to not do this. 14:29
a weak one, but one I didn't think of until I dug down into the code.
colomon …. ~~ Callable?
masak these :nth indices are 1-based, as opposed to everything else that handles *-1 14:30
in a way, that actually makes 2 and *-2 *more* symmetric, not less.
but it may be a reason to exercise caution.
colomon adds a +1 to the code he was just writing 14:31

arg, very true, but that was meant to be "masak is totally expanding the spec" 14:40
masak :)
I have a weak preference against allowing arbitrary Callable inside of :nth
I can't verbalizy why. 14:41
verbalize*
it feels like a hobgoblin to me.
geekosaur feels downrigth nasty to me because it implies you do the whole thing and then backtrack to match the Whatever 14:43
even worse for arbitrary Callable
masak I can't think of a use case where I would want to do the -> $n { ... } thing rather than the *-$n thing
colomon geekosaur: you do do the whole thing
masak or maybe (very rarely) the */2 thing
colomon geekosaur: but the magic is you only do it if someone uses this functionality 14:44
geekosaur: :1st will not do it. just :nth(*-1)
geekosaur still feels a litle too magic. maybe hold ti in abeyance for consideration for some future version...
14:44 Alina-malina joined, Alina-malina left, Alina-malina joined

psch grmls at forgetting to set PANDA_REPORT_TESTREPORTS

geekosaur I think colomon just claimed its weight is very light?
if so, then maybe. (althought here is more than implementation weight. does supporting that syntax muck with the parser too much?) 14:47
colomon geekosaur: I meant allowing *-1 there, masak is worried about the distinction of allowing Callable versus WhateverCode

jnthn Whoa. Before I went on my last work trip, my r-m build was about 60s. Now it's about 67s. Wonder if that's something local or something that's changed.

timotimo can you explain it to me a bit?
moritz $_ is globally scoped

so that they don't clobber the outer $_

it will print 142
