colomon sorear: nextwith works again? 00:29
sorear colomon: nextwith has always worked, but the semantics changed recently 00:34
colomon I was under the impression you'd removed it recently because of the semantic change. 00:35
sorear ah, no, sorry about that - I removed uses of it from the compiler
00:35 nacho joined
colomon I'd hesitated messing further with panda because I knew panda used it. 00:35
00:35 nacho is now known as Guest34864
sorear in order for the compiler to work on both new-niecza and old-niecza, it can't use nextwith at all 00:35
colomon so imagine my surprise again when I tried my version of panda and it Just Worked.
sorear: ah, gotcha. 00:36
I'm working on getting Math::Prime niecza friendly atm.
sorear cool
sorear is currently trying to get $obj.::('Foo::Bar') to work 00:38
colomon success! just used my (installed) version of panda-niecza to install Math::Prime. 00:39
it's less than completely elegant, but it works 00:40
sorear WOW
colomon++ # panda-niecza actually working?!
colomon there are a couple of issues which still need to be resolvedd
right now it's hard-wired to use my personal install of niecza
00:41 shinobicl_ left
colomon I need to figure out a better approach than that. (normal panda just calls a perl6 executable) 00:41
and there are some warnings that should be silenced (or possible represent bugs that need to be fixed)
but yeah, it works 00:42
(oh, and there are issues with a lock file not being cleaned up if an install aborts)
sorear hmm, is END working for you?
colomon I don't know. (panda is definitely not trying to use it.) 00:43
jnthn sleep &
colomon there's probably a spectest for it, no?
jnthn: 'night
00:45 dorlamm left
sorear colomon: yes, there are a few END spectests (which weren't working for [Coke] at one point) 00:45
colomon .... looks like the END spectests are mostly marked todo. :( 00:46
errr, they're all eval based.
sorear ascending-order has nontodo END tests 00:47
colomon looks like it does work for me. (Just tried END { say "In end!" }; and it printed okay.) 00:48
so if I can figure out the lock thing, I maybe can fix it that way.
00:51 Maddingue left
tadzik colomon: wow, that's awesome! 00:51
colomon tadzik: most of the changes have been basically cosmetic, it definitely ought to be possible to re-merge the versions in the long run 00:52

colomon sorear: with 797fd44, spectest is clean except for the usual S02-magicals/env.t fail. 01:13
tadzik: hmmm, I've still got some sort of issue here 01:23
it's .panda/state 01:26
~/.panda/state 01:27
01:30 Yary joined
colomon just installed HTTP::Easy, though it doesn't seem to have much in the way of tests, so who knows if it works. 01:32
sorear: seems like $! is giving us problems in panda-niecza? 01:43

sorear moritz: known bug? 08:39
moritz bug?
you didn't put $_ in the signature
sorear there is no signature, so it defaults to \$_ = $OUTER::_
moritz for blocks, yes 08:40
for subs, the implicit signature is based on the presence of @_ and %_
sorear STD has the same implicit signature rules for blocks and subs
moritz that seems wrong 08:41
it means you can't do stuff like sub f { for 1..2 { say @_[$_] } }
because then the @_ ends up being in the signature of the block, not the sub
, 08:42
also when rakudo tried to implement those semantics back in the days, nobody knew how $_ and @_ interacted
sorear so there's something in the prose spec that contradicts STD.getsig? or is this an @Larry decision that somehow never got recorded? 08:43
moritz I don't think the specs well enough to tell
but I do know that $_ and @_ don't interact well in any intuitive way 08:44
perl6: sub f { say $_ }; f 3
p6eval niecza v13-378-g20aa772: OUTPUT«3␤»
..rakudo 9719f7: OUTPUT«===SORRY!===␤CHECK FAILED:␤Calling 'f' will never work with argument types (int) (line 1)␤ Expected: :()␤»
..pugs b927740: OUTPUT«␤»
moritz if the spec says nothing about it, I'd assume p5 behavior in having $_ not interact with arguments passed to subs 08:45
niecza: sub f { say $_.perl; say @_.perl }; f 1, 2, 3
p6eval niecza v13-378-g20aa772: OUTPUT«Any␤(1, 2, 3).list␤»
moritz niecza: sub f { say $_.perl; say @_.perl }; $_ = 5; f 08:46
p6eval niecza v13-378-g20aa772: OUTPUT«Any␤().list␤»
moritz that doesn't make any sense, if $_ defaults to OUTER::$_
nom: =begin 08:48
p6eval nom 9719f7: OUTPUT«===SORRY!===␤Preceding context expects a term, but found infix = instead at line 1, near "begin"␤»
moritz nom: =begin foo
p6eval nom 9719f7: OUTPUT«===SORRY!===␤Preceding context expects a term, but found infix = instead at line 1, near "begin foo"␤»
sorear moritz: the presence of @_ suppresses the generation of a $_ par ameter, so you're seeing the mainline $_ 08:49
niecza: say ({ 5 }).signature
p6eval niecza v13-378-g20aa772: OUTPUT«:(Any \$_)␤»
sorear niecza: say ({ $_ }).signature
p6eval niecza v13-378-g20aa772: OUTPUT«:(Any \$_)␤»
sorear niecza: say ({ $_, @_ }).signature
p6eval niecza v13-378-g20aa772: OUTPUT«:(*@_)␤»
sorear niecza: say ({ $^foo }).signature 08:50
p6eval niecza v13-378-g20aa772: OUTPUT«:(Any $foo)␤»
sorear hey, I just noticed I could probably port Math::Model now
moritz but the mainline $_ is 5, no?
niecza: sub f { say $_.perl; say @_.perl }; $_ = 5; f
p6eval niecza v13-378-g20aa772: OUTPUT«Any␤().list␤» 08:51
sorear erm... I think niecza does a 'my $_' in routines by default
if $_ is not created by the signature
I'll wait for the ruling 08:52
moritz my next suggestion would have been to wait for TimToady++, right :-)
sorear I should start on announce.v14 RSN too

fasad one last thing, how to assign same value to all the array elements?
masak could have a better error message.
sorear masak: what do you propose?
masak fasad: my @a = $value xx $length;
sorear fasad: arrays go up to infinity. Assigning the same value to *all* of them could take a while 09:26
masak sorear: "Variable @b not predeclared (did you forget parentheses?)"
fasad sorear: couldn't it be lazy?
sorear masak: you think that's better than what STD already does?
masak fasad: lists are lazy, arrays are not.
sorear: oh!
sorear: didn't read properly. :/ 09:27
fasad btw, rakudo complains about @b being not predeclared. Its warning has room for improvement !
masak though I do think that "parens", cute as it is, is a less well-known term than "parentheses". 09:28
fasad: yes.

tadzik colomon: re ~/.perl6 and ~/.niecza, do we assume that Rakudo modules are different than Niecza modules?
colomon tadzik: that's been my assumption, though in practice, a lot of modules can go both ways 12:58
tadzik I'd assume they're the same .pm files 12:59
colomon or perhaps the right way of saying it is modules should be installed separately for the two compilers even if they're the same .pm files.
tadzik well, do they?
I'm thinking about some sort of perl6-switcher tool (more) 13:00
masak good post-noon, tadzik
tadzik it'll keep modules for both, and when you do perl6-switcher rakudo, 'perl6' executable becomes /path/to/rakudo, and ~/.perl6 becomes ~/.perl6-switcher/rakudo/ or something
sort of like perlbrew manages multiple Perl fives 13:01

colomon yeah, that would be another interesting way of handling the situation.
tadzik It feels wrong to me to have both ~/.perl6 and ~/.niecza. Because then, why not ~/.rakudo and ~/.niecza? And then, what is perl6 after all? 13:02
moritz well, I'd say ~/.perl6/rakudo and ~/.perl6/niecza
colomon tadzik: well, I was trying to present a solution that wouldn't require changing how rakudo works; but obviously switching to ~/.rakudo makes more sense. ;)
tadzik imho, it doesn't :P 13:03
I think .niecza has a right to use ~/.perl6 as much as rakudo does, if you know what I mean
masak +1 13:04
here's my take on it: outsiders will always expect to run a 'perl6' executable.
that's why Rakudo got on in the first place.
there's a strain of thought saying Rakudo is encroaching on the 'perl6' name, but I don't think that's it. 13:05
no more than any particular C compiler is squatting the 'cc' name.
colomon right -- but when you install GCC (for instance), it installs "gcc" and /usr/lib/gcc... 13:06
masak I didn't say all compilers install themselves on /usr/bin/cc 13:07
I'm saying there is more than one that does.

colomon which cc
lrwxr-xr-x 1 root wheel 32 Jun 13 2011 /usr/bin/cc -> ../llvm-gcc-4.2/bin/llvm-gcc-4.2 13:09
If Rakudo installs "rakudo" and Niecza installs "niecza" and they use ~/.rakudo and ~/.niecza, then the perl6 executable can be whatever the user wants. That's a fine solution in my book. 13:13
(And yes, "perl6" can change just like perlbrew) 13:14
jnthn Either ~/.[rakudo|niecza] or ~/.perl6/[rakudo|niecza]/ seem workable to me. 13:15
colomon +1 13:16
moritz in the long run, do we want a shared installation dir, with custom subdirs for implementation specific files?
if so, we might want ~/.perl6/lib for .pm6 files, and ~/.perl6/rakudo/blib/ for .pir files or so 13:17
colomon moritz: I'm hesitant about shared installation dir, just because it seems like the cleanest way to avoid having modules which only work on one implementation muddle up the other implementation is to have separate include paths. 13:18
might be particularly important in the case where a module compiles but doesn't actually work (ie tests fail so it won't install in an implementation-specific /lib) 13:20

fasad forgive my ignorance, what's a signature ? 14:54
masak fasad: though if it shouldn't work -- and I strongly suspect it shouldn't -- then there should be a compile-time warning, really.

fasad masak: what is so signature-ly about it? 15:03
Radvendii oh wait 15:04
that's not a bug
i didn't see that it was all()
masak fasad: it's not signature-ly, it's an actual signature. 15:05
fasad tadzik: nailed it. i had only removed the parens but forgotten to split each my onto a different line 15:06
masak fasad: and the reason you could even use a '=' inside of it is that '=' means "default value" in signatures. however, default values only make sense for functions, not for variable initializations.
masak gets a vague sense he's been submitting an RT ticket about this once
fasad masak: sorry, i meant why is it called a signature? #in 'my ($a, $b, $c)'
masak fasad: hm, dunno exactly. 15:07
fasad: probably because it's how the function identifies itself to the world.
fasad the 'my' function ?! 15:08
masak nono, in the case of 'sub foo($x)'. 15:09
and then signatures are simply re-used for 'my' variable initialization.
but it's not a perfect match, and some things will not make perfect sense outside of function declarations.
'my ($x is copy)' doesn't make much sense either.
fasad masak: hmm. 15:10
jnthn Note that when you do a list assignment based on a signature, it just does the variable decls and degenerates to a simple Parcel. 15:12
fasad so to be clear, when declaring more-than-one array with 'my', i should not try to initialize them too. correct?
jnthn I suspect it should whine about signatures that are too complex to do that to.
Radvendii ummm... i have a ghost variable 15:13
i'm getting an error about variable $v
and i've checked every instance of the letter 'v' in my program
fasad jnthn: i'm still trying to understand the word 'Parcel' !
Radvendii $v doesn't exist in any form
# such as $^v $!v $.v $v, etc 15:14
masak jnthn: I'm of two minds about actually allowing defaults in 'my' declarations.
jnthn: I can even see real use cases for nested siggie declarations :)
jnthn masak: So long as you don't expect it to have any influence whatsoever on the assignment that follows... 15:15
masak: But that'd seem isleading
*misleading
masak: The defaults...yeah, that could be useful I guess.
15:17 shinobicl_ joined
masak jnthn: there isn't always an assignment after the declaration. 15:19

Radvendii oh, right, but isn't it better practice to overload at_pos than postcircumfix:<[ ]>? 16:21
masak in general, yes. 16:25
but you asked how to declare the :delete adverb.
it's the same kind of distinction as with "BUILD" and "new". if you want to do ordinary things, you're fine with using build. if you want to do fancy things like change the method signature, you use new. 16:26
Radvendii but how do i not touch anything else? let's say i want to have it accept :delete, but not do anything else differently from normal [] (not even do anythnig with :delete) 16:28
do i have to re-write the whole method? 16:29
masak yes. 16:31
as things are currently factored, yes.
this is a general problem in design.
you have to factor things in *some* way, and anticipate the ways people want to break things apart and put them together again. 16:32
but factorings are always tradeoffs, and you can't please everybody.

like, for example, this 'given' changing variables business

but i assume that's not exactly what it does...
17:07 pomysl left
eviltwin_b perl has a longstanding thing of *binding* variables in blocks, not copying. that is, $_ is an alias to $x there, not a copy of it 17:12

masak Radvendii: it seems your data is very confused. you're actually getting things in some context, and you don't know whether they're strings or numbers, and you don't know (but need to know) whether they've been overloaded with 'but'? 18:34
something tells me you're using power tools where precision tools would do you more good.
Radvendii nono, they're strings. i just wanted to be *sure* because i'm still getting a feel for the language 18:35

Radvendii assumes lexpad has to do with lexical scopes?
moritz yes 19:50
Radvendii cool
19:50 jferrero joined
masak Radvendii: if I had to guess, what you're seeing is the given block anchoring to the lexpad of the first invocation, and then when the lookup for $a is done in the second invocation, it finds the wrong -- the old -- OUTER for the given block. 19:52
at least that's a hypothesis consistent with the data. 19:53

jnthn Yes, it's another upshot of the FAIL of doing lexical capture at block entry. 20:10
At first glance.
masak but "doing lexical capture at block entry" sounds like it should work in this case. but it doesn't. 20:11
Radvendii slightly unrelated but: why do we even use "given" wouldn't "for" do the same thing on a scalar?
masak it would. 20:13
but not on a list.
also, 'for' has loop semantics; 'given' doesn't. 20:14
Radvendii oh, that makes sense 20:16
