b2gills jnthn: the biggest problem I see with your batch change to t/harness is that subroutines are always globally scoped, so it doesn't make a lot of sense to put it inside of an if block. 00:03

japhb b2gills: *named* subs are package-scoped in Perl 5, true, but *anon* subs aren't. So just change 'sub batch {' to 'my $batch = sub {' if that matters. The thing that makes me chuckle is that it's a functional solution in a way Perl 5 people don't often do. They'd more likely process each batch as it was created, rather than make an array of batches and map over it. 00:47
Actually, I wouldn't be surprised if recent Perl 5 has my-scoped subs, but I stopped paying attention when 1) I spent a whole bunch of accumulated favors at a previous job just getting them to switch to 5.10 so I wouldn't have to go insane with some RHEL default, and 2) Perl 6 came along. 00:51
*2) A working Perl 6 compiler came along.
b2gills Perl5 does have lexical subs, if you precede them with `my` added in 5.20 00:52
perldoc.perl.org/perl5200delta.html...ubroutines 00:53
oops it was added in 5.18: perldoc.perl.org/perl5180delta.html...ubroutines
00:58 colomon joined
b2gills I was actually thinking of adding `sub rotor (\@$@) {...}`to bring something like a P6ism to the harness since it is likely to be edited by someone who is more comfortable in Perl6 than Perl5. The biggest problem is that Perl5 doesn't have pair objects, so you would always have to call it as `rotor @a, 50 => 0, 25 => 0`. 01:00

07:33 JimmyZ_ joined
masak I wonder if we'll ever get good "model refactoring" tooling, like we have relatively simple refactor actions today for Extract Method etc. 07:34
model refactors are trickier, but often far more interesting.
moritz what do you mean by "model refactoring"? 07:35
change the data model?
masak could me something like, I had a hash somewhere, but now I want to switch to a set instead.
so I have to change not just the declaration, but all places that use that data structure. 07:36
moritz aye
another common one at $work is "move an attribute to a different object"
masak right, that'd count too.
right now in 007 I have a situation where I'm changing array-of-thing to array-of-hash-of-thing. 07:37
it's error-prone to find and change all the places that use this data structure. I'm glad I have the tests, at least.
moritz one notes that static typing would also help find the places.
masak indeed. 07:38

TEttinger that single quote screws up the whole syntax highlighter
they haven't released since 2013 and the build has been broken for all of 2015

TEttinger: oh, that's sad news :/

08:15 abraxxa joined
masak style survey: `%h{$key}:exists`, or `%h{$key} :exists` ? 08:19
08:21 abraxxa left
moritz the former 08:21
I think of it as postcircumfix:<{ }>(:$exists!)
so it belongs to the } as close as possible
(in fact, I'm slightly surprised it doesn't go on the inside 08:22
%h{$key :exists}
masak :)
I think I can motivate to myself why it doesn't go on the inside. not sure I can verbalize it, though.
something like, adverbs that modify ops come after the op. it's mostly a coincidence that {} has an inside. 08:23
of course, that answer is a little bit like saying "it's not X because it's Y".
arnsholt My parser intuition says that allowing the adverb inside the circumfix would make the parsing gnarly 08:24
masak arnsholt: because adverbs are otherwise so easy to parse? :P
08:24 laouji left
arnsholt Gnarlier, then =p 08:25
08:25 laouji joined
masak "gnarlier" is a good slogan for adverbs in general... :P 08:26
timotimo well, there can also be , inside the { }
so it's a bit strange to have %foo{"bar", "baz" :exists}
masak timotimo: right.
timotimo on the other hands, named arguments are already like that
masak this looks like it deserves to be linked here: stefan-marr.de/papers/pldi-marr-et-...ogramming/ 08:27
TEttinger timotimo, woah, using Atom now, very slick, and it successfully handles [']
but

TEttinger it fails on the very next line with ["] 08:27
timotimo haha
oh man
grammars really are a tiny bit difficult every now and then 08:28
i wonder: is gnome shell supposed to take about 1 gig of ram?
maybe right now is the time to get back to xfce.
arnsholt I'm really happy with XMonad, FWIW 08:31
TEttinger github.com/atom/language-perl ok, so this is what it uses. the line that causes it to fail is here, github.com/perl6/nqp/blob/master/e...h.nqp#L231 08:33
open source syntax highlighters are nice :)
08:34 abraxxa joined, laouji joined
TEttinger and I'm wondering, what type of... grammatical construct? is it that ["] is not the start of a string 08:34
masak it's in a rule, yes?
TEttinger oh! 08:35
masak hm, isn't it <["]> ?
TEttinger and it breaks github's syntax highlighting too
pretty much, masak
| <?["]> <quote_EXPR: ':qq'>
masak right. 08:36
that's a zero-width character class.
...I think the term is. :)
TEttinger a double quote with no closing quote?
that's practically a negative width thing... 08:37
masak both the opening and closing quotes are parsed by quote_EXPR
which is why the `?` is there in `<?["]>`, because it's not consuming the `"`
jnthn Generally, you can make any <...> assertion a zero-width lookeahead by starting with ?
TEttinger ah, so the syntax highlighter needs to be aware of '?'
jnthn <foo> # call rule <foo> and capture if it matches 08:38
<?foo> # call rule foo, check it matches, but don't advance the cursor
uh, and I meant "rule foo" in the first one
jnthn still waking up :)
TEttinger ok, I still don't know why it can have one double quote with no closing quote 08:39
masak should I call it "zero-width", or "positive lookahead"?
08:39 laouji left
jnthn TEttinger: quote_EXPR matches an opening and a closing 08:39
masak TEttinger: what I said above.
TEttinger I mean in that line of source
masak TEttinger: it's a zero-width match!
jnthn Oh, you mean the syntax highlighter bug
TEttinger yes
jnthn Yes, no idea about that :)
masak it shouldn't count the " as an opening close, is the short answer.
TEttinger ok 08:40
masak more generally, it shouldn't count anything inside a char class as an opening quote.
or an opening anything.
char classes are very special environments wrt parsing, and they do tend to confuse syntax highlighters for this reason.
regex syntax is already a DSL, but charclasses are even DSL-ier than that.
TEttinger where a char class is anything within /<.*\[.+\]>/ 08:41
is that the right uh regex
timotimo well, ".*" is a bit much
masak TEttinger: right, modulo things like `?` and other stuff.
TEttinger .?
masak well, `<- ["]>` is OK too, IIRC.
maybe just check STD :) 08:42
one of the silliest workaround patterns I know in Perl 6: creating an IIFE just to be able to use `~~` in an action method. :) 08:44
08:44 laouji joined
TEttinger so under what conditions do the contents of <THE STUFF IN HERE> get parsed as a character class? 08:44
masak TEttinger: when there's also a `[]` in there. 08:45
TEttinger x < y[0] && y[1] > z
masak TEttinger: but I don't know if that's a good way to explain it to the parser.
right.
TEttinger hm
masak TEttinger: maybe check how STD has it?
TEttinger I don't even know what STD is other than something I don't want to need to be tested for 08:46
masak heh.
github.com/perl6/std/blob/master/STD.pm6 08:47
TEttinger thanks
timotimo what's an IIFE?
masak timotimo: "Immediately Invoked Function Expression". it's a JavaScript term. 08:49
timotimo: in this case, the sub insulates against the grammar's $/ and gives a fresh one to match with.
TEttinger oh wow. github can't even syntax highlight STD.pm6 08:51
github.com/perl6/std/blob/master/S...#L283-L286
timotimo ah
i think github uses the same highlighter as textmate and atom and such

TEttinger is this then, timotimo? github.com/perl6/std/blob/master/STD.pm6#L5218 09:03
09:03 cognominal left
TEttinger timotimo: the syntax trouble stems from trying to highlight <?["]> 09:03
also, <?[']>
if I wasn't clear, this is not a problem with Perl 6, this is a problem with an implementation of syntax highlighting for it 09:06
timotimo i know :)
TEttinger but I definitely don't "get" the syntax well enough to fix this
timotimo could be the ? trips the parser up. possibly also <-["]>?
TEttinger so... somewhere in std.pm6 there's a list of what is valid in a cclass, syntactically, right? 09:07
09:10 laouji left
TEttinger github.com/perl6/std/blob/master/S...5144-L5151 maybe? 09:10
09:13 laouji joined, uncleyear left
TEttinger brain... hurts 09:13
timotimo those are things valid between < and > 09:14
it might get easier when you notice that <sym> inside the token just matches what's in the :sym< ... > at the end of the token's name
so token assertion:sym<...> { <sym> } simply matches "..."

TEttinger timotimo, eh? I thought the <> in <|> was part of the syntax for any sym stuff, not just syms inside <> in the src you're reading 09:22
DrForr <<"\x[1234]">> # is legal as well, for example...
09:22 uncleyear left, uncleyear joined
timotimo you are right; it's just that the < > from assertions and from :sym are overlapping right now 09:23
TEttinger oh ok
so the assertion always is in <>
timotimo i meant to refer to the parts from here "token assertion:sym<|> { <sym> [ <?before '>'> |" to there 09:24
to hopefully keep your head from hurting :)
TEttinger heh
09:24 itz joined
timotimo it seems i worded my attempted explanations poorly and made matters worse :D 09:24
TEttinger oh no, this is very "meta" stuff, using perl to parse perl
so there's going to be a lot of confusion however it goes 09:25
so should I post a github issue on github.com/atom/language-perl so they know that it doesn't parse charclasses correctly when they contain quotes? 09:27
or does someone want to send a PR fixing the relatively small perl 6 file? 09:28
masak the trick with very "meta" stuff, metacircularity, and things parsing/evaluating themselves, seems to reside in acknowledging that you are dealing with two things ("parser"/"parsee") which just happen to be the same thing. 09:29
itz hmm the average perl6 module has pod or markdown visible from github rather than via p6doc Module::Name after install 09:31
09:31 laouji left
TEttinger ...do they even handle character classes? github.com/atom/language-perl/blob...l%206.cson 09:31
timotimo TEttinger: i'd prefer that to be fixed in textmate's perl bundle and having it re-converted again
itz maybe panda should append such pod to the main module

TEttinger hm. github.com/atom/language-perl/pull/39 09:35
timotimo well, the perl6.cson file is separate from the perl.cson file 09:38
though there's probably a derivation of some kind going on?
TEttinger I didn't see one 09:41
timotimo the perl6.cson file seems pretty small 09:44
can it be complete without deriving from the perl.cson file? 09:45
well, it is just a syntax highlighting definition file, not a complete grammar
itz if perl6 is written in itself is it possible to use its own grammar from externally to parse itself? 09:49

timotimo muraiki: porting to the JVM has forced us to make the "current working directory" completely virtual, which fortunately means we can have one per thread, rather than a process-global one. you can just have a "my $*CWD = '/...'" before your invocation and it should work - if not, please report bug 14:48
muraiki timotimo: thanks! although it looks like nqp::spawnprocasync takes a cwd arg, so I think adding it to Proc::Async would be pretty straightforward. that way if you wanted to do a few commands with different cwds in one thread, you wouldn't have to juggle them (such as saving the original cwd for a later command) 14:50
timotimo if you "my $*CWD", you don't have to remember the original value; if you leave the block you've defined it in, you get the original value right back 14:51
muraiki so I'd just put a bunch of blocks in one thread?
I see
I guess I just like being able to supply it in the constructor :) but thanks, that will solve my problem 14:52

FROGGS[mobile] hi lizmat!
lizmat FROGGS[mobile] o/ 16:06
hoelzro jnthn: regarding that loop (my $i = 0;;) issue in RT (alledged variable escape), I can see how that would be confusing. Is there something we can do to clarify that for people? 16:07
lizmat but isn't that a genuine scoping bug ? 16:08
jnthn No, it's not a bug.
The rules in Perl 6 are very clear.
timotimo i don't think the my $i is scoped to the inside of the () and { } only
lizmat ok, then it's a case DIHWIDT
jnthn If it's inside the the curlies of a closure, or in the signature to a block, then it's scoped to the block. Otherwise it's not. 16:09
We could perhaps better document that.
lizmat some people might think it's a "signature" of the loop
jnthn I don't think we need to stress much over it, though.
Uses of "loop" should be rare anyway.
lizmat agree, DIHWIDT :-)
jnthn Given we've ranges and sequences... :) 16:10
lizmat well, yes, but the people who try to program C in Perl 6, *will* be confused by this I guess
hoelzro jnthn: I don't think it's a bug; I'm just wondering if there's something we should do to caution people when they do something like loop (my $i; ...)
16:11 pat_js left
hoelzro lizmat: in C99, it's scoped to outside of the block, isn't it? 16:11
[ptc] hi #perl6, why does `for $file.IO.lines[^Inf] <-> $line { $line ~~ s:nth(5)/\s/;/; $line.say }` give Cannot assign to an immutable value
hoelzro I know in C++ it's not
jnthn And in C89 I'm not sure you can even do it. :)
[ptc] whereas `my @lines = $file.IO.lines[^Inf]; for @lines <-> $line { $line ~~ s:nth(5)/\s/;/; $line.say }` doesn't (and runs) 16:12
hoelzro jnthn: I think the documentation was clear (it wasn't hard for me to find the section in S04 that I linked), I'm just wondering if a compiler warning would be smart
jnthn hoelzro: I don't think it warrants a warning
masak seeing another Parrot release go by, I'm struck by how many types of parrot are called something with "Lovebird".
lizmat but I guess 'for ^Inf -> $i { say $i; last if $i==5 }' is a better idiom than loop (my $i = 0; $i++; $i==5) { }
jnthn Because most of the time, unless you do declare another $i later, you're not going to have a problem. 16:13
We could put a hint on the "already declared" error
hoelzro alright, good point
profan so that's scoped outside of the loop block itself?
i mean, the "loop" construct doesnt have its own scope in that context
jnthn profan: Correct, loop doesn't get to be an exception to the rule. 16:14
lizmat masak: was there a Parrot release?? I didn't see it?
jnthn And in the for case, there's no problem 'cus the loop variable is a block parameter.
hoelzro: There's already a request in RT for the "already declared" message to point to where the previous decl was 16:16
hoelzro: I guess we could try and keep enough info around to give a hint about loop.
hoelzro it would be a nice to have 16:17
I just want people trying Perl 6 to not get confused, and I remember tripping up on if my $value = $something { ... } back when I was learning 16:18
16:19 uncleyea1 joined, uncleyear left
jnthn Yeah, there the idiom you tend to want is "if something() -> $value { ... } 16:19
hoelzro right 16:20
but a lot of people (esp. Perl 5ers) may try if my $value = something() { ... } and get confused when that variable "escapes" 16:21
but you're right that the redeclaration warning is probably sufficient
jnthn wonders if this is mentioned in the 5to6 in doc 16:24
[ptc] could someone explain the difference between `for $file.IO.lines[^Inf] <-> $line { $line ~~ s:nth(5)/\s/;/ }` (which gives an error) and `my @lines = $file.IO.lines[^Inf]; for @lines <-> $line { $line ~~ s:nth(5)/\s/;/ }`, which doesn't?
jnthn Yes, it's mentioned
[ptc]: In the second case you've (eagerly) assigned to an array @lines which puts everything into a Scalar container 16:25
[ptc]: In the first case, you're iterating through a lazy list of lines and there is no container
Use "-> $line is copy" to make the first work out
[ptc] jnthn: ok, so that's why it's not possible to assign to $line in the loop?
jnthn Correct
iirc though, we should never have allowed $line to be bound to a non-container 16:26
(with <->)
[ptc] ah, ok. Just trying to get an example to work again, and am wondering why it doesn't work
jnthn So the error should have come a little earlier.

The code `for $file.IO.lines[^$lines] <-> $line` iterates over a lazy list of lines without a container, thus it gives the error `Cannot assign to an immutable value` (since `$line` is immutable in this case). To enable
  `$line` to be writable within the loop, one needs to replace `<-> $line`

spintronic ah ok thanks masak!
tony-o $! doesn't auto create accessors/setters for you
masak JimmyZ_: `has $attr` gives you an `$!attr` but allows you to call it `$attr` in the class scope.
JimmyZ_: because it doesn't have a `.`, it doesn't give you accessors.

skids Really it looks like eventually binding could be "prime, and if there are no leftover args, you successfully bound" 18:03
jnthn Well, note that the bind code is implemented separately on JVM, and in most cases on MoarVM for normal binds we never use the binder, we compile the signature 18:04

timotimo jnthn: where would i have to look to put in diagnostics for why binds sometimes don't get compiled on moar? 18:05
skids And yeah implementing the JVM .assuming stuff would be a learning curve for me, not knowing any java.
jnthn skids: What particular behavior of assuming are you wanting to implement? 18:06
skids A few. There's an RT complaining about the arity of the result, and the spec says you can pass whatever stars in to curry x and z but not y in :(x,y,z)
jnthn skids: Faking up a signature/arity/count?

synbot6 Link: rt.perl.org/rt3/Public/Bug/Display...?id=109322
timotimo because sometimes i see "bind" and "bind_one_value" and friends at somewhat high places in profiles
skids BTW I found RT#125437 while looking over the binder code.
synbot6 Link: rt.perl.org/rt3/Public/Bug/Display...?id=125437
jnthn skids: I don't think you've have to change the binder to do those
timotimo usually not as high as the reify gang, but i'd expect them to almost always disappear completely 18:08
and they end up with very high call counts sometimes
bbiab
jnthn timotimo: I'd put something in Actions.nqp
skids No don't have to, just wondering if there is a reason not to factor code for reuse in BOOTSTRAP, like is it not efficiently compiled or something.
jnthn timotimo: There's a line "if lower_signature(...)" 18:09
timotimo: Add an else to that if and you can log which blocks don't be their sigs lowered
skids: Well, the other big reason is that we don't use that code path at all on JVM; iirc it's in #?if moar... 18:10
skids jnthn: yes, I'm aware. But I don't think(?) things are introspectable enough yet to do all these things from Perl6. 18:11
Also a missing part is how, once I have the new Signature, to attach it to the code block that does the call with the combined capture. 18:13
Unless using EVAL is a performant option. 18:14
Oh, and one other question was under what scenarios "unnamed capture parameters" appear. 18:17
jnthn One option would be to have the code object be mixed in to, so that .signature/.arity/.count respect the assumed signature 18:18
You could even lazily work those bits out if they're asked for
skids That's an idea, for sure. 18:20
jnthn You may need to use nqp::ops to manipulate the Signature
Well, almost certainly will 18:21
skids Yeah there's no useful Signature.new, was a problem. The other is if we want .assumming to blow up at that code line when impossible priming parameters are provided.

Would lvoe second opinions, but that looks busted
The VAST::Adverb is on the scope declarator 21:16

timotimo looks like something TimToady ought to have a look at 21:20
21:20 zacts left
jnthn Yeah, that's what I'm concluding, given every alternative I can think of has drawbacks 21:21
timotimo ISTR timtoady wrote what he'll be doing tomorrow; traveling?
21:22 muraiki left
jnthn Yeah, though maybe I can get an answer if he drops by :) 21:22
timotimo that'd be nice 21:23
jnthn .tell TimToady in STD, "my $exists = @foo[0]:exists" puts the adverb on the whole scope decl, because adverbs have item assignment precedence, put the initializer preclimits to item assignment. In Rakudo we wrongly had preclimit doing exclusive, not inclusive, checking, so we never noticed until now. 21:24
yoleaux jnthn: I'll pass your message to TimToady.
masak jnthn++ 21:25
jnthn .tell TimToady s/put/but/. Also I don't immediately see a good fix; I suspect changing adverb's prec will have bad effects, but initializer doesn't feel like the right change either. Ideas welcome. :) 21:26
yoleaux jnthn: I'll pass your message to TimToady.
21:26 salva left
masak jnthn: my mental rule for what the adverb ends up attached to is "look backwards, find the root of the sensible AST fragment". what you're saying here is that it finds the '=', not the '[0]' ? 21:26
21:26 nowan_ left
masak well, the '=' *is* a higher point in the AST than '[0]'... 21:27
jnthn masak: According to the VAST, it finds the whole scope decl 21:28
masak: Thing is, the = there is not parsed as an infix
masak: Initializers are a special form.
masak oh?
oh, right.
jnthn Thus why we hit the preclimit.
I suspect this issue can be made to manifest itself somehwere else, though, with enough creativity 21:29
21:29 nowan joined
jnthn sub foo(@a, $b = @a[0]:exists) { } # probably also suffers it 21:29
masak well, thinking about it, I wouldn't mind if adverbs couldn't go on initializers or assignments. I've never wanted that, and I can't recall anyone ever expressing a need for that.
jnthn masak: Right, I think we agree that "my $exists = @foo[0]:exists" should see the adverb go onto the @foo[0] 21:30
masak: The problem is that in Rakudo it only did because we had a bug with preclimit handling.
masak nodnod
jnthn masak: And when I bring us in line with STD, I uncovered that STD also has this wrong.
masak intriguing!
fix one thing, another problem plops up.
it's like a waterbed of correctness ;)
jnthn Something like :) 21:31

masak naptastic: only when you use open/close delimiters is there a parsing problem.

masak naptastic: I never quite understood what the parsing problem *was*, but it's a limitation I freely admit resides in me, not in Perl 6 ;)
naptastic That's... going to take some getting used to. 21:53
I use s{}{} all the time, to avoid the 'dancing matchsticks' effect
