moritz good morning, #perl6 06:31
raydiak \o moritz 06:34
raydiak moritz: did anything change about JSON::Tiny in the past month which could possibly cause arrays of pairs to be returned where there should be arrays of hashes? 07:17
raydiak moritz: ignore that, the problem has to be elsewhere 07:30
FROGGS o/ 07:31
raydiak \o
tadzik raydiak: yes 07:54
panda had the same issue, but it turned out to be lacking an update 07:55
raydiak tadzik: thanks, that's exactly what it was...had a stale JSON::Tiny floating around in a forgotten place, masking out the new one 07:58
masak morning, #p6 07:58
raydiak morning masak 07:58
masak and a fine morning it is! 07:59
diakopter <-agrees
dylanwh 6 08:07
diakopter sometimes 6 anyway 08:10
dylanwh that was me moving this to position 6, which seems fitting 08:12
moritz knight X 6
moritz killed dylanwh
:-) 08:13
mathw morning 08:18
diakopter mr walton 08:19
mathw jnthn: Excellent fosdem talk! Really positive picture of Perl 6 :)
o/ diakopter
FROGGS mathw: and the good thing about that picture is that it is the truth :o) 08:20
masak what a strike of fortune! 08:21
but yeah, even though I *know* all the inside-echo-chamber news that jnthn writes about in his talks, reading about the way he phrases them always puts me in a better mood :> 08:22
mathw it'd be a pretty awful talk if it wasn't true :)
moritz agrees 100% with masak
mathw I'm not so much in the echo chamber these days so it was good for me to get such a good overview - although as it turns out, I knew about most of that as it was 08:23
The surprise for me was the constructor parameters field assignment thingummy including destructuring
diakopter agrees, but much of the debugger interface was news to me
mathw I just saw the slides so I didn't get that bit
Debuggable grammars makes me very happy though 08:24
diakopter at least, I think it was the debugger
the audio wasn't there at that point
diakopter oh noes, not the netsplits 08:26

Ven wat
timotimo could it be that ?? !! isn't autocurried correctly? 10:42

timotimo m: [1, 2].map({$^a > 1 ?? "a" !! "b"}) 10:44
camelia ( no output )
timotimo it would appear to be the case :\ 10:44
i've already sacrificed a bit of my sanity the last time i looked into autocurrying 10:46
moritz the question is: should ?? !! be auto-curried? 10:48
masak don't see why not.
diakopter BOOTSTRAP.moarvm::4294967295
masak it really only needs to be transparent to the currying that already happened with * > 1
diakopter that's a big file 10:49
timotimo diakopter: you suspect something's very wrong?
diakopter no :)
masak diakopter: curious that it's *exactly* 2**32 - 1 10:50
diakopter only a few thousand wrong
timotimo moritz: i'm sure it should be autocurried at least in the very first slot of ?? !!
masak what timotimo said.
timotimo the other two, i'd be willing to be convinced it shouldn't
i think there's a lot of WAT to only autocurrying the first parameter
moritz doesn't want to convince anybody, just want to raise the question
timotimo hm, actually 10:51
if you have something like $foo ?? * !! * - 1
you would probably be surprised to see that it generates a closure with *two* arguments
moritz aye 10:52
and you might actually want to return a closure
timotimo and folding these two into one argument seems like a pretty huge WAT
moritz aye
timotimo ?? !! thunks, right? 10:53
maybe the rule should be "if it thunks, it won't autocurry", in which case we'll have to consider xx for a moment, too
moritz note that xx doesn't autocurry anyway, because xx * just means "infinitely many" 10:55
timotimo oh, that's right & good
er, but what about the left side? 10:56

masak is seeing stars
timotimo should it, though?
nobody seems to want to step forward :) 11:00
luckily, in most situations, an explicit closure with implicit arguments is just a few characters more to type and a tiny bit less pretty to look at 11:01
(though always a lot cleaner and simpler to understand)
masak timotimo: I... I think it should, unless there is an overwhelming reason it shouldn't. 11:03
timotimo: so the LHS of infix:<x> and infix:<xx> should probably autocurry, yes.
as well as the first argument to infix:<?? !!>
timotimo should this be a spec ticket? or should we just highlight larry? 11:08
diakopter r: say (* xx 50000).perl 11:09
camelia rakudo-parrot 44ab3c, rakudo-jvm 44ab3c, rakudo-moar 44ab3c: OUTPUT«(timeout)»
timotimo obviously the result of * xx 50000 should be a closure with 50000 arguments! 11:10
diakopter :)
Ven I definitely don't think (* xx 5) should be totally different from ($^a xx 5) 11:18
that seems very confusing
jnthn Ven: Uh, those have to be different. A placeholder parameter is *always* scoped to the current block. Parens don't introduce a block. 11:22
(*+2) is not ($^a+2), it's {$^a+2} though.
FROGGS hi jnthn 11:23
jnthn o/
jnthn is about to take his class to lunch :)
om nom nom students
uh, I mean...
timotimo ohai jnthn :)
Ven definitely
some errors are pretty cryptic. "use of uninitialized value of type Int in numeric context" gives file:line "src/gen/CORE.setting:655" 11:24
timotimo yeah, that's unhelpful 11:25
i'm pretty sure there is or was something in place to keep that from happening? 11:26
Ven add ALL the `say "alive"`s
timotimo as in, it should give the file/line of the thing using whatever is causing the problem
Ven actually I didn't need that complicated stuff ... damn 11:30
timotimo did you try out Rakudo::Debugger yet?
Ven timotimo: perl6-debug can't parse my file :( 11:31
timotimo huh?
Ven `do given ... { when` gives an error on the `when`
timotimo what's the error you get?
that's weird, it re-uses the existing grammar
Ven just running perl6 instead of perl6-debug works though 11:32
timotimo so in theory everything that rakudo parses, it should be able to parse :(
Ven well :(
no debug for me this time it'd seem 11:34
timotimo can you do a sanity check with the debugger on any random piece of code to see if it works at all?
Ven timotimo: sanity check passes 11:36
timotimo if you have any spare time, you could try to golf the parse problem and open a ticket on jnthn/rakudo-debugger 11:38
that would be quite nice
FROGGS since it is included in rakudo it would be a rakudobug
Ven mmh hard to isolate :( 11:42
OK reproduced it 11:45

Ven yeah okay, it doesn't show up in the .new() arguments but it's there nevertheless
moritz of course it doesn't show up
how would .perl know which arguments you passed to .new?
timotimo moritz: so if you could get a BUILDSLAVE that gets called with the "rest of the kwargs" or something, that'd be fine? 12:07
moritz timotimo: finer, yes 12:08
timotimo: Moose also has a nice system where you can provide a method that turns a list of positional arguments into pairs for the actual constructor
Ven moritz: it could store it D: 12:09
But anyway, got it working. moritz++ timotimo++
Just a bit slow ...
timotimo yeah, slow is still the normal way for perl6 programs to run :(
moritz it wouldn't reproduce the original object if a mutator was called in the mean time
Ven gist.github.com/Nami-Doc/7fe3b9744d369c9450c5 -- That's what I have so far 12:10
timotimo what does that mean? 12:11
Ven timotimo: that's fine though :) 12:12
moritz Ven: if you allow setting of attributes through the constructor, why make them private?
Ven I'm happy I got it working
moritz: just an old habit of not making something public unless there's a need to access it from outside
changed anyway 12:13
I need something a bit more consistent, but I'm already happy it works (kinda) ^o^ 12:15
is there an equivalent -MO=Deparse ? 12:26
timotimo not yet, no 12:30
but you can get the ast with --target=ast or --target=optimize
Ven timotimo++ # More than what I need ! 12:32
timotimo :) 12:33
and --target=parse will give you the parse tree of your program
Ven timotimo: This gives me "could not locate compile-time value for symbol Block" 12:39

that's not helpful

colomon err… so once I've installed Rakudo::Debugger, what am I supposed to get? I seem to have executables named perl6-debug.c and perl6-debug.nqp, but no perl6-debug 13:45
?
timotimo colomon: you should have perl6-debug
you may need to check with Build.pl in the rakudo-debugger repository
colomon I'm installing it via panda, for what that's worth 13:46
timotimo that's the correct way to install it
huh. now i get a perl6-debug-m 13:47
but my "perl6" is a perl6-p
tadzik hah 13:48
timotimo i wonder why perl6-debug-m doesn't get chmod +x 13:49
colomon how does that work? I'm looking at Build.pm right now, and it doesn't seem to know anything but parrot 13:50
?
tadzik I think panda does +x for all the things that come from bin
timotimo yeah, but perl6-debug-m comes from rakudo
rather than panda
tadzik oh
brother the 13:52
timotimo maybe create-moar-runner should be taught to set +x
FROGGS colomon: forget about jnthn's repo, it is in rakudo itself 13:53
colomon FROGGS: errrmm… so what is the correct procedure to build the debugger?
FROGGS colomon: I would suspect that installing rakudo should suffice 13:54
timotimo it ... is?
jnthn timotimo: (doesn't get chmod +x) 'cus I did it, and forgot taht, 'cus it don't matter on Windows.
timotimo even the frontend?
colomon FROGGS: I did git pull, and rebuilt, and I don't have a perl6-debug executable in my path, I don't think.... 13:55
… hmmm, perl6-debug-m is there 13:56
but not an executable.
FROGGS froggs@TL02L-R8RXTCW-linux:~$ which perl6-m
/home/froggs/dev/nqp/install/bin/perl6-m

-rw-r--r-- 1 froggs froggs 315 Feb 4 21:20 /home/froggs/dev/nqp/install/bin/perl6-debug-m
correct
jnthn The debugger stuff is in a transitional state. I started getting the perl6-debug-* being built in the Rakudo build
But I only did it for Moar so far
colomon was hoping for perl6-debug-p
timotimo ah, that explains it
jnthn I didn't have time to do -j and -p yet
colomon jnthn++
jnthn I needed -m for my FOSDEM talk which is why it got done first ;) 13:57
FROGGS well, should not be too hard to fix it
colomon 's track record of getting the debugger to work continues to be terrible. :)
jnthn And then the rakudo-debugger repo is just going to be a normal Perl 6 module that supplies the UI.
And so should be a completely easy Panda install

timotimo matplotlib.org/basemap/users/examples.html - maybe get there from something like this?
btyler moritz: I'd suggest doing searches with 'shapefile' in them. here's a result that looks promising: thematicmapping.org/downloads/world_borders.php -- there are tools to convert shapefiles into svgs, but I haven't used them personally 16:49
indeed, a perl5 tool which does just that: carto.net/svg/utils/shp2svg/ 16:50
moritz btyler: thanks! 16:51

lucs vendethiel: Search for "Perl 6" in that thread; it appears that yes, it's true for perl6 too. 18:49
PerlJam wonders what "it" is exactly. 18:50
vendethiel ouch =(
lucs it -> "Perl can be statically parsed"
vendethiel can't*
lucs Er, right :)
PerlJam Then, it is correct that Perl 6 can not be statically parsed, in general. :) 18:51
vendethiel but the OP's original problem does not exist in perl6, right ? Arguments just won't "disappear" 18:52
outside that, yeah ofc adding new operators with different precedence, makes it harder to statically analyze, but that applies to a wide variety of languages 18:54
even haskell has that
FROGGS you just have to declare a sigilless variable to confuse it with a subroutine... 18:55
you dont have that problem, in say, PHP
vendethiel oh, sure, which doesn't make it a good language :P 18:56
lizmat raiph: yes I did, but It don't see the connection. It was related to array slicing code I was discussing with jnthn in Brussels 18:58
grondilu doesn't the fact that P6 has proper function signatures removes the need to determin if a function is unary? 18:59
*nullary
kurahaupo_mobile grondilu: function signatures aren't really the point 19:01
kurahaupo_mobile the point is that multiple glosses of the code are possible, and choosing between them requires *running* some code 19:02
jnthn Sure, that's the trade-off you make by giving a language a BEGIN block. 19:04
Or BEGIN-time things at all 19:05
(Such as use, which can export new operators, etc.)

lizmat jnthn: wrt to .made / .ast: I removed .ast from the spec completely, but suggested in the commit message that .ast would be like .made, but with an implicit check for ASTness 19:24
would that make sense to you? Or would you consider the overhead such an extra check prohibitive ? 19:25
jnthn lizmat: Well, but what does "an AST" mean? 19:26
As in, what would be actually be checking for?
lizmat ~~ Qast::Node ?
jnthn I don't think that's the only kind of AST in existence 19:27
Heck, MAST exists...
lizmat well, some kind of sanity check, so that problems in grammars are caught more easily? 19:28
jnthn What kinds of problems are you thinking of? 19:29
lizmat where make sets a string, and .ast expects an AST ?
jnthn That feels like a rather rare kind of bug 19:30
As in, I can't remember a concrete example like that.
jnthn More typically it's a missing or mis-named action method... 19:30
lizmat ok 19:31
but what would be the added value of having .ast ?
other than historically / what you're used to
PerlJam It would give you an idea of how to use it in your grammars.
(just the name) 19:32
jnthn In some situations, .ast just conveys a bit better whta is going on.
lizmat and on the other side, you would see in the parameter to "make" that it was an AST as well
PerlJam I was trying to think ... is there another name (besides AST) for the bit of data you generate as you parse? 19:33
lizmat my suggestion was "pot / .pot"
jnthn Well, it goes well with toke...nizing...
lizmat 1. To put (something) into a pot.
2. To preserve by bottling or canning. 19:34
3. To cause a ball to fall into a pocket.
and as a noun:
1. A vessel used for cooking or storing food, or for growing plants in, especially flowers 19:35
2. (poker) The money wagered in poker or similar games.
3. A trap for catching lobsters, crabs, eels, or fish.
anyways :) 19:37
PerlJam If "made" is a synonym for "ast", what's the corresponding synonym for "make"? :) 19:40
moritz "ast", for "abstractify syntax tree"
PerlJam maybe "tsa"? (it's the flip side of the operation :) 19:41
PerlJam (But that has some other, unfortunate connotations as well) 19:41
lizmat perhaps "cook" / ".eat" 19:46
[Coke] etooclever
moritz cook / .nom
lizmat bake / .fried 19:47
PerlJam peg / ... somethign that goes with peg 19:48
jnthn pug?
PerlJam clearly I've only half a mind about this subject
lizmat "A harlot; a prostitute. [circa 1600]"
PerlJam peg was a nod to Parsing Expression Grammar 19:49
lizmat fill / .dig
lizmat is off for some more post-FOSDEM recovering
PerlJam make/made has the nice aesthetic of both being the size 19:50
moritz dig/.dug 19:51
jnthn lizmat: haha, that's pug? :) I was thinking of cute past tense of peg...and of a dog :)

vendethiel: but no need to subscribe to any list; just write a bug report per e-mail

[Coke] if the goal is to be able to roundtrip that match, adding another type doesn't help if you can include both types in your matched string.
you need to escape the string rather than add more quotes.
