'night, timotimo
psch this is confusing me gist.github.com/peschwa/8625806 00:03
why does the error change to undeclared variable? 00:04
jnthn psch: Double quotes interpolate variables 00:06

psch oh 00:14
Mouq psch: so what I think you were looking for is `is`, and I think you'll have to define a sub other than 'say'
psch right
Mouq psch: Hey, it's better than no test :)
psch i don't know if a test that always passes is better than no test... :) 00:15
that's what i get for only having used throws_like up to now hah

psch i feel fairly confident it's correct.

Mouq psch: Nergle, sorry, I was offline 00:39
I read the bug report more as `routine (my $a) = 1,2,3` being parsed as `(routine (my $a)) = 1,2,3` when it should be `routine ((my $a) = 1,2,3)` 00:41
psch that actually makes sense, the other cases don't work when removing the routine 00:42
in my defense, the usefulness of the test did improve... :)
i'll change it again though, you're clearly right
Mouq lol, psch++ it's more than I've done today :) 00:43
Ok
psch i'm not quite sure how to write the test though 00:44
00:44 sivoais joined
psch r: use Test; is 'foo (my $a = 1,2,3)', (1,2,3), 'Routine call taking a parenthesesed my as argument works.'; # this isn't right 00:44

psch so is doesn't eval it's 1st argument
but eval_ok probably has the same semantics as ok, except it evals first
Mouq r: use Test; sub low-prec (\i) {True}; is (low-prec (my $a) = 1,2,3), True; is $a, (1,2,3) 00:46

psch right, i had declared a sub foo($x) { $x } locally for the example above 00:48
r: use Test; sub foo($x) { $x }; is foo (my $a = 1,2,3), (1,2,3), 'Routine call taking a parenthesesed my as argument works.'; # this maybe?

psch nope
well, yours works

psch how do verify the bool value inside a method of an exception in throws_like? 02:03
i have this: gist.github.com/peschwa/8627020
but the warning is unsettling 02:04
if i leave out the smart match the last test case fails...
i also don't quite understand how an "always fail[ing]" smart match gives a successful test result
02:05 krunen joined
psch "leave out the smart match" here means just putting 'private => { False }', which in retrospect doesn't really seem to make sense to me either 02:05

psch colomon: i dont quite get your worry there. do you have your local git repo hosted on a networked filesystem? 02:09
colomon psch: I'm editing the files over SSHFS. 02:10
and, apparently, committing them over SSHFS, too. 02:11
psch that's fine, isn't it 02:12
if your repo is mounted locally from another computer you edit and commit on the other computer
colomon apparently
psch a possibly troublesome scenario would be mounting a subdir of the repo via sshfs and then commiting... 02:13
of course after editing inside that subdir
but as long as you mount the root of the repo i don't see any cause of concern

psch in fact, i think im gonna try that out now 02:17
remounting a subdir of a remote with unpushed changes in another repo without those changes and then changing things inside the subdir
i'm fairly confident git will complain
"could not commit hanged contents of $file" 02:21
psch is pretty sure he doesn't exactly understand that error
that's actually kind of interesting 02:22
after adding a file in the subdir, then "mount -o bind"ing the subdir into a clean repo i had to commit in both repos before i could rebase into the one i "mount -o bind"ed from 02:23
psch has no idea what that actually means 02:24

raydiak what does "is pure" do? 09:04
timotimo it's meaningful to the optimizer 09:05
it will constant-fold only things that are marked is pure
raydiak means "no side effects" or similar?
timotimo that's right 09:06
or "no side-effects to worry about"
caching, for example, would be allowed
raydiak makes sense 09:07
timotimo and if you want you can mess with the optimizer that way :P

timotimo yup
raydiak is inlining happening?
well, dumb question in the context of constant folding 09:10
timotimo heh.
raydiak I guess I was wondering if inlining works in general
timotimo we do inline simple things
09:10 daxim joined
raydiak simple? 09:10
timotimo not exactly sure about what exactly constitutes a simple thing 09:11
i'll give you a link to the source code
raydiak read my mind :)
timotimo github.com/rakudo/rakudo/blob/nom/....nqp#L2541
raydiak ah, I see 09:12
timotimo wether or not an op is inlinable can be seen in the Ops.nqp or QASTOperationsMAST.nqp and friends 09:13
on JVM and moar, the default for an op is to be inlinable, on parrot it's the other way around iirc 09:14
raydiak none of the args can be optional, capture, slurpy, lol, bound to something somewhere else, or constrained, to name a few
timotimo i'd think some of those could be made to work, but it'd be ... work :P 09:15
raydiak I've been looking at the rakudo and nqp source lately...it's remarkably coherent and legible
timotimo i wholeheartedly agree 09:16
unfortunately, to a beginner, that doesn't mean you'll immediately know just what to write :P
raydiak not at all, but I tried reading the source once or twice with p5, and decided I didn't want to sacrifice that much of my life :P
timotimo has seen some of the insides of pypy and it was a similar deal to nqp and rakudo 09:17

FROGGS the arabic question mark is a bit off here in my chat client, but the customm postcircumfix works
jnthn wtf
oh
ffs, it's RTL
:P
FROGGS wtf -> ftw
:P
jnthn Yes, I wrote ftw but it was in RTL, you see :P
FROGGS hehe
'course
jnthn wtf ++SGGORF! 20:12
diakopter what's trl
FROGGS \o/ <-- rtl even
jnthn Well, I just grabbed JDK8 and it seems Rakudo on JVM builds and spectests on it... 20:13
masak oh, I had to go to the web logs to even see what you guys were so confused over...
FROGGS weird is, that is shows the arabic ? correctly after the 123 when I highlight the text... 20:14
jnthn However, Java's substring semantics have changed, and the time to do JAST -> classfile has gone up a bunch...
diakopter masak: how is 123-1-2 formed 20:15
lue Having two of those RTL question marks seems to keep it from breaking completely, but I could be wrong there. ‮Now at least you didn't use weirder Unicode characters...‭
FROGGS damn, now that I fully implemented postcircumfix, Perl5::Terms infiniloops when precompiling it
diakopter: it gets the invocant as the first arg, and the stuff in the postcircumfix after that 20:16
diakopter what's in the postcircumfix
FROGGS 1, 2
diakopter where's the 2
FROGGS after the one :o)
diakopter don't see a 2 20:17
FROGGS perl6-m -e 'sub postcircumfix:<* *>(*@a) { @a.join("-") }; say 123*1, 2*'
123-1-2
here, ascii
lue diakopter: try selecting the text, see if you can move around the text doing that.
diakopter that's not what mine looks like at all
FROGGS the right-to-left char messes up, that's all
masak diakopter: three arguments go in: the 123, the 1, and the 2. 20:18
diakopter nopasting my problem
masak diakopter: I didn't even see the confusion, because my client didn't RTL things.
FROGGS I (sort of) see "... 1232 ,1??" 20:19
lue masak: aw, then you missed my joke earlier :)
masak lue: must've, yes.
diakopter FROGGS: yes, that's what I saw 20:20
lue irclog is willing though, at least: irclog.perlgeek.de/perl6/2014-01-26#i_8178625
jnthn I just tried to type what I saw, but when I copy-paste the RTL char it makes it impossible to type what I want :P
FROGGS hehe 20:21
moritz iirc gtk tries to handle RTL correctly
lue moritz: works in gtk-using hexchat at least (Unicode OVERRIDE characters included ☺) 20:22

arnsholt Blah. Does anyone happen to know which particular bit of code in NQP/JVM inserts the exception handler that intercepts stray exceptions?
jnthn arnsholt: Maybe you mean invokeDirect? 21:02
arnsholt: Or you mean something in code-gen?

jnthn It's so good it's worth pasting twice!
sjn it's so good it's worth 404ing it? o_O
arnsholt That might be doable
Aha! NQP_VERBOSE_EXCEPTIONS=1 21:18
jnthn: Are there any VM-specific bits to Rakudo's container stuff? 21:20
jnthn arnsholt: Yes. 21:21
arnsholt: container.c for Parrot and MoarVM, and a couple of java classes (that should have container in the name) are in rakudo-runtime.jar
arnsholt Right 21:22
There's something weird with "my $x = CArray.new" on JVM, might look like an unimplemented REPRop or something
jnthn Oh? 21:23
What error are you seeing, ooc?
arnsholt On JVM, ``use NativeCall; my $x := CArray[int].new; $x[0] := 1; say "alive"'' works, while ``use NativeCall; my $x := CArray[int].new; $x[0] = 1; say "alive"'' fails with "java.lang.RuntimeException: This type does not support positional operations"
Er, s/:=/= in the second one
So binding the CArray to $x works fine, but assigning doesn't 21:24
jnthn lemme glance NativeCall...
21:24 jerry_ joined
arnsholt The verbose exception thing shows that the error is coming from P6Opaque 21:24
It works fine on Parrot
21:26 rindolf left
jnthn wonders how on earth the binding case works at all 21:27
arnsholt Heh
jnthn On this line: 21:28
nqp::bindpos_i(arr, nqp::unbox_i($pos.Int), $v);
try an nqp::decont(arr) instead.
arnsholt Sounds plausible
Prints alive \o/ 21:29
Thanks!
jnthn \o/ 21:30
arnsholt That might be the cause for some other weirdness I'm seeing with JVM and CArray too, actually
jnthn Put in the nqp::decont to Zavolaj; I think we'll want them for Moar too
arnsholt Probably
I'm gonna add some tests to the CArray suite anyways. Turns out the CArray implementation on JVM wasn't quite as complete as I imagined =) 21:31
jnthn yay :)
arnsholt So I'll be a good TDD citizen and write some tests first =)

FROGGS it is an indirect method call that happends all the time, and Perl5::Terms is huge so it tries to match this postcircumfix almost everywhere in that code
I guess it will succeed, but not today :o(
night masak
so, I am ripping out that postcircumfix from v5 21:51
jnthn I'd not imagine it's *that* slow...
FROGGS jnthn: shall I commit that postcirumfix code for rakudo anyway?
jnthn LTM should stop you ending up there, no?
FROGGS: Yes, preferably with a spectest or two for custom postcircumfixes...and provided it doesn't break anything else, of course. 21:52
FROGGS jnthn: I already spectested it
jnthn: maybe LTM does not catch because $starter is not a literal? 21:53
jnthn FROGGS: But it's in a parametric role, iirc? 21:54
And those are constant after interpolation
The NFA stuff has a some stuff in for genericity of this kind...
