[Coke] I can now build partcl on nqp. but running it dies with: A method named 'backtrack' already exists in class 'PAST;Regex'. It may have been supplied by a role. 01:24

sorear Radvendii: I use 'rlwrap mono[-sgen] run/Niecza.exe' personally 01:32
Radvendii: niecza is carping about [||], which IMO doesn't make much sense
Radvendii sorear: to which comment are you responding? 01:33
sorear 14:30 < Radvendii> what does niecza mean by "This macro cannot be used as a function" 01:34
13:45 < Radvendii> Is there a way to get command history on niecza? (Like, i know CPAN offers it only after you download some module or something...)
Radvendii ah
thank you
sorry, I couldn't remember what i had said

02:32 wolfman2000 joined
Radvendii but why no output before? 02:33
sorear Radvendii: 'note: 5' is a noop statement that happens to have a label 02:37
you could use goto "note" elsewhere to go to the 5
Radvendii oh right 02:38
but then why "func: args"?
it's not a function...
benabik nom: <a b>.grep({say $_})
p6eval nom 052cc6: ( no output ) 02:39
Radvendii it's not a function...
damn it
benabik Huh. That does do output on my computer.
Radvendii i keep tabbing into iTerm and then hitting "up-enter" to recompile my program, and accidentally being on IRC :P
benabik: not on mine. what version of rakudo are you using? 02:41
benabik 2011.12-145-ged943e6
Radvendii ah. i'm using 2012.01 02:42
it must have broken
02:45 Chillance left
Radvendii gah! 02:45
i keep forgetting to put my variables in //s when I regex them
sorear Radvendii: you shouldn't put anything with side effects in the argument to grep 02:49
Radvendii huh? 02:52
i keep doing <w b>.grep: {$l !~~ $^x} which only matches if $l doesn't "eq" $^x.... 02:53
wait
i do have it in //s
e.g. /$^x/ 02:54
oh
you were talking about the other thign
why shouldn't you put side effects in grep?
so long as it returns False or True...
nom: say ?(<w b>.grep: {'wK' !~~ /$^x/}); say ?(<w b>.grep: -> $x {'wK' !~~ /$x/} #is this a bug? 02:57

Radvendii there we go
why are they different?
03:20 whiteknight left
gfldex looks like a bug to me 03:22
03:22 orafu left 03:23 orafu joined
sorear Radvendii: because grep is lazy and you can't rely on the sub being called in a specific order or at all 03:23
gfldex but the bug might be in a different spot then you think it is
sorear I die a little every time you write <a b>.grep({ say $_ }), Radvendii
Radvendii :P o-oh that's right. lazy. that makes sense. sorry about the death and all. 03:24
gfldex Radvendii: you may want to read perlcabal.org/syn/S05.html#Variable...erpolation 03:25
benabik sorear++ # don't die 03:26
Radvendii OH! 03:28
so what i want is /<$var>/
:D
gfldex maybe 03:29
Radvendii nom: my $var = 'w'; say 'wQ' ~~ /<$var>/
p6eval nom 052cc6: OUTPUT«=> <w>␤␤»
Radvendii nom: my $var = 'w'; say 'wQ' ~~ /$var/ 03:30
p6eval nom 052cc6: OUTPUT«=> <w>␤␤»
Radvendii oh
fooey
so what's the difference?
gfldex at times it helps to bang you head against the wall until you forget anything you know about Perl 5 before you write "use v6;"
03:30 shinobicl___ joined
Radvendii :P 03:31
gfldex the difference is that <$var> forces the match engine to look for a rule with the name that is stored in $var
unless you stick a regex into $var, then it should use that regex in place
if you stick anything that is not Str|Match into $var, well good luck to you 03:32
Radvendii oh. i figured out what my problem this time with them was, it didn't have to do with <>s or such. (and that makes sense, from what you're telling me) 03:34
but i find it odd that .grep: {'a' ~~ /$^x/} should have different results from .grep: -> {'a' ~~ /$x/}
unless you tell me that there's a reason for that 03:35
gfldex $^x will be defined, $x will not be defined 03:37
whereby defined is not in the perl 5 sense defined
you imply that grep is calling the function with a parameter 03:38
i would not bet on that
if it would, you would get the same result for both cases
sorear Radvendii: you get different results because you forgot to add $x to the signature in the second case
gfldex he did not 03:39
03:39 Psyche^ joined
sorear {'a' ~~ /$^x/} is equivalent to -> $x {'a' ~~ /$x/} 03:39
Radvendii oh
i did forget
but that's what i menat
meant*
gfldex sorear: scroll up please
Radvendii when i do supply $x as an argument
the later version works correctly 03:40
the former does not
sorear possibly Rakudo is getting confused because // is a block itself, maybe the parameter is getting attached to the Regex block rather than the Block block

Radvendii that's what i've been experiencing

it's not a problem with you
I might even say bug 03:44
Radvendii thanks for the assurence, i tend to assume everything is
sorear perl6: my $foo = { 'cat' ~~ /$^x/ }; say $foo.signature

sorear Radvendii: remember that a Regex is just a funny kind of Sub, and it has a scope of its own 03:45
Radvendii sorear: oh. that's weird. not expected at least... well, i know now
gfldex and a block inside a Regex is a funny kind of sub aswell
Radvendii i knew that much 03:46
why didnt the above code work?
gfldex mine?
Radvendii yeah
gfldex because the regex engine called the most inner block with no parameter 03:47
Radvendii ah
gfldex that's a runtime error
Radvendii i see
sorear $^x, to a first approximation, attaches to the innermost curlies
gfldex: No, it's a compile time error. Notice the '===SORRY!==='
Radvendii those variables are like extra $_s
gfldex wow, perl 6 got quite clever already
sorear blocks embedded in a regex are forbidden to have parameters 03:48
gfldex: STD has caught this case for at least a year

ah b: does anyone use that anymore?
sorear looks like b doesn't do it 03:49
03:49 plutoid joined
sorear Radvendii: yes 03:49
Radvendii sorear: for real? for what?
sorear Radvendii: nom still has more rough edges than b does
Radvendii oh
sorear so, officially, we tell production users to stick with b for now
Radvendii i see
sorear where 'production' approximately means 'star' 03:50
iiuc there's a star release planned for next week
gfldex there are quite a few things that nom does better thought
Radvendii gfldex: such as?
gfldex better error messages as a start 03:51
it's a fairly long list
Radvendii mhmm
okay
(that wasn't meant to be doubtful, just asenting) 03:54
benabik Ah.... 04:13
Figured out the grep issue, I think. 04:14
Grep returns something lazy, so if you never ask for the values, it never calls the sub.
nom: (<a b>.grep: { .say })[0]
p6eval nom 052cc6: OUTPUT«a␤»
benabik Radvendii: ^^ 04:15
Radvendii benabik: yup. we were discussing that earlier. essentially, the take away lesson is never put code you want to run in a grep statement 04:16
benabik Oh. I got distracted in the middle here, missed that convo.
I was building a new copy of nom trying to figure out what "broke". :-D 04:17
sorear o/ benabik 04:18

Radvendii there is something that we believe "broke" 04:19

tadzik hehe, been reading hacker news, haven't you? :)
snarkyboojum why the truncation?
:P

snarkyboojum @tadzik
sorear you can't get more than ~17 useful digits out of a general Num
snarkyboojum how do get a useful 100 digit number out of it? :D

TimToady if we can have a pi spigot, we can certaintly have any other kind of spigot 06:15

sorear it wouldn't hurt to be better than everyone at everything, but it's not much of a priority of mine atm 06:18
snarkyboojum I particularly like the association with "bunghole" for some reason

moritz timotimo: subroutines and subroutine lookup are both lexically scoped

masak moritz: not sure I understand your distinction.
moritz masak: if it help you, think of $*foo variables, which can be declared lexically, but looked up dynamically 14:25
*helps 14:26
masak moritz: so you're talking about the scope on the one hand, and the lookup chain on the other? 14:27
it's like the declaration and the use have to make contact, and both have different reach.
or may have different reach. 14:28
moritz correct
masak but it's important not to be sloppy there. dynamic *variables* are still looked up statically/lexically. their *values* are looked up through the call chain. 14:29
14:29 jaldhar left
masak similarly with private attributes. 14:29
moritz huh
masak er, not a good comparison :)

masak I thought you had to do 'my $*a' even with dynamic vars...
jnthn masak: They're declared in a given lexical scope.
masak right.
jnthn masak: The lookup of them is entirely dynamic.
masak ok.
jnthn: it's weird, I distinctly remember us talking about this at the 2010 YAPC::EU attendees' dinner. 14:31

moritz remembers discussing macros with masak++ in breakfast hall of the hotel in Copenhaagen 2010 14:34

masak remembers that breakfast discussion too 14:36
that's when we first realized that ASTs aren't closures, but still need to retain the lexical environment in which they were created.
then we forgot it for a while, and now we're back to being aware of it ;) 14:37

pmichaud even ?%hash works 15:27
similarly, ?@array works nicely without having to reify all of the elements of @array :-P
masak even ~%hash works!
:P
pmichaud as opposed to +@array, which does reification 15:28
fsergot :)
masak oh, true.
yeah, I wouldn't write +@array in my own code.
jnthn assumes if @array { } works out just the same as ?@array
masak I prefer my casts to be implicit.
jnthn: yah, cus 'if' boolifies.
jnthn Right. 15:29
pmichaud since ?@array is better than +@array for checking non-emptiness, I recommend ?%hash over +%hash for the same reason.
s/for the same reason/for consistency/
jnthn fwiw, in Rakudo, ?%hash will also be faster than +%hash, though only marginally.
pmichaud a bit more than marginally, if you turn around and use the results in a boolean context 15:31
jnthn True.
pmichaud if ?%hash { ... } is likely to be faster than if ?+%hash { ... }
jnthn Oh, for sure. I was more meaning that ?@array vs +@array is potentially the difference between O(1) and O(n), whereas ?%hash and +%hash are both O(1), just varying in constant factor. 15:32

anytime you build a new parrot, you have to get a new NQP based on it

jnthn Makes sense. :)
Yes, working is generlaly preferred :)
*generally
pmichaud if we do that, then --gen-parrot and --gen-nqp can always refer to the "retrieve copy via git" option, while --build-parrot={dir} and --build-nqp={dir} can be the "use the source already in {dir}" option. 15:49
and star's Configure.pl can default {dir} when they aren't supplied.

bbkr jnthn: should I report a bug with this one?
moritz that also works
jnthn bbkr: I think I know what's going on. 17:01
moritz for example if you want to call postfix:<i> (imaginary number) on a variable, you have to write $x\i
timotimo ah, i see
TimToady or ($x)i
moritz because $xi would parse the variable with identifier xi
jnthn bbkr: The short answer is that you should be using has $.y = $!x;
TimToady in any case, $x.i is something else
timotimo does the \ serve other purposes other than separate things where no space would be allowed?
TimToady sure, \t is still a tab :) 17:02
moritz nom: say 'foo'.\ uc

timotimo of course
moritz nom: say 'foo'\ .uc
p6eval nom 6eae67: OUTPUT«FOO␤»
moritz useful if you want line breaks or vertical alignment
TimToady is thinking about allowing an X. infix
jnthn bbkr: The long answer is that your $.x call is virtual so it touches an attribute in the subclass, which we didn't initialize yet. Touching it results in a kind of auto-vivification. Then, when we get to applying the defaults, we see the attribute $!x in the subclass was already touched so don't re-initialize it.
timotimo oh, you can put an arbitrary amount of whitespace there?
neat.
moritz we call that "unspace" 17:03
TimToady \ as a hide newline falls neatly out of it too
jnthn bbkr: I don't actually consider it a bug BUT the fact we let you write $.x there and not at least warn is a bug.
moritz jnthn: I thought reading should never result in autoviv
not even here, I'd say
jnthn moritz: It's not vivification per se. 17:04
moritz: It's that the REPR lazily generates the scalar container.
moritz: Touching $!x forces it to do so. The fact it's done so makes it consider the attribute "touched" and thus it won't get initialized.

timotimo does perl6 offer something like ruby wherein you can "open up" an already defined class and add new stuff? 17:44
bbkr timotimo: yes, MONKEY_TYPING
TimToady if you say "use MONKEY_TYPING;" and then use "augment"
PerlJam Radvendii: It's okay if you let Perl 5 be your default assumption about how Perl 6 works, as long as you are flexible in adjusting that immediately :)
timotimo oh god, how terrible :)
PerlJam timotimo: exactly!
TimToady indeed
an idea straight out of Ada
"with UNCHECKED_TYPE_CONVERSION" 17:45
Radvendii TimToady: i still like MONKEY_TYPING better. :P it's got a perl6 zing to it
TimToady well, the Ada declaration was for unsafe conversions, not monkey typing 17:46
bbkr timotimo: class A {}; use MONKEY_TYPING; augment class A { method foo { say "banana"}}; A.foo
TimToady we used to call it monkey patching like everyone else, but monkey typing is funnier
PerlJam FAQ: I always expect to get the works of Shakespeare when I use MONKEY_TYPING, is there something less confusing?
bbkr timotimo: where A{}is somethong you got from somewhere
TimToady and it is, in fact, changing the type
timotimo when does perl6 get A_THOUSAND_MONKEYS_TYPING?
TimToady now that's an idea 17:47
PerlJam timotimo: whenever it is needed.
Radvendii but in all seriousness, you've gotta use "augment" anyways, why require people to use MONKEY_TYPING?
TimToady to punish them for it
PerlJam Radvendii: To *really* discourage people from doing it. 17:48
TimToady and to put something right up at the front that their boss can see
Radvendii :Þ why?
PerlJam Radvendii: it's destructive enough that they should have to think at least tqice before doing it.
bbkr Radvendii: to distinguish hacks and experiments from production code
PerlJam er, twice
Radvendii i guess... 17:49
but no thinking twice before overloading ';' eh?
:P
TimToady monkeys don't usually think of that
and there's not a major language *cough* like Ruby *cough* that does that 17:50
PerlJam Radvendii: ruby has made monkey patching a way of life, so there's a whole slew of programmers ready to do it. How many programmers do you know who think to overload .... blah TimToady types too fast

TimToady chained operator really need to act like a function with multiple args: chain:['<=','<=']($a,$b,$c) or some such 19:19
or chain([&[<=],&[<=]], $a, $b, $c) 19:20
19:20 jevin joined
TimToady so that it threads the N-way comparisons correctly 19:21
awwaiid you gunna make a 3-op and 4-op and 5-op version of that?
oh wit
I misread
TimToady well, it's slightly problematic to thread a *@foo parameter
awwaiid chain is the function that takes a list of ops and a list of thigns to go between them 19:22
forget I kabitzed anything
TimToady but I don't think we currently autothread slurpies, so it is potentially a real problem
might have to gen such a function at need, or treat Any *@terms specially 19:23
sorear I'm sure something can be done
TimToady there's something vaguely macro-y about it, that wants it to pretend there's a variadic list of non-variadic parameters... 19:24
I'm sure something can be hacked too, but it'd be nice if it just fell out from some other generaliztion 19:25
*zat
otoh, it's supposed to short-circuit, so we really need to be passing a list of thunks, which is probably harder to get the typology right on, if we're going to rely on type mismatch to dispatch junctions outside of Any 19:29
0 > any(2,3) > die "phooey" # shouldn't die 19:30
so that part of && semantics can't go away
niecza: say 0 > any(2,3) > die "phooey" 19:31
p6eval niecza v13-358-g301a891: OUTPUT«any(Bool::False, Bool::False)␤»
TimToady another possiblity if it gets too intractable is to prohibit junctions after the 2nd term, and define chain($, $, *@ [&]) or so 19:34
19:35 kaleem left
TimToady chain($, $, Callable *@) is perhaps more readable 19:35
oh, forgot the operator list, but you take my meaning... 19:36

Updates to enable --gen-parrot and --gen-nqp to accept directory path values.
jnthn back 19:38
sorear o/ jnthn, pmichaud 19:39
TimToady the basic problem is that you can't know the lazy callable is going to return a junction until you call it, and then you're already past the junction threader dispatch 19:40
sorear oh, hmm
and that makes it difficult to implement the &/| precedence rule :| 19:41
TimToady maybe junctions have to transitively thunk their parts when they find themselves thunked 19:42
so we know it's a junction argument, but it evaluates the junction itself lazily
or just a specially marked junctive thunk 19:43
basically we need to turn Thunk of Junction into Junction of Thunk for chaining, and perhaps other thunky spots 19:49
gah, I've been trying to backlog all morning, and failing, and soon I will throw a lunch exception... 19:50

pmichaud for me, it's a toss-up
19:52 PacoAir joined
TimToady masak: the trouble with promoting {} to Block is that you don't know it until someone actually calls .() on it 19:53
so we'd have to make Hash respond to .(), and probably succeed only if the Hash is empty 19:54
jnthn TimToady: Ah, and it's line 2042 where it checks the <term> flag, if I follow correctly?
jnthn thinks he sees what's going on :)

19:55 bluescreen10 left 19:56 mj41 joined 19:57 birdwindupbird joined
sorear hopes TimToady's Lunch exception is resumable 19:58
TimToady maybe {}.() should warn "{} better written as {;}" if we can pass the original line info through to the run-time 20:01
or maybe it should just silently DWTM 20:02
like we try to do with other allomorphic literals 20:03
20:03 GlitchMr left
TimToady the difference here is that {} has to be mutable 20:04
and it's a bit bogus to respond to () after you've put data into it 20:06
but the thing is, there are many places where {} is perfectly fine for an empty block, so we probably also need to treat it as one when binding to Callable 20:07
otherwise we suddenly have the situation that built-ins are different from user-defined control structures
20:08 bluescreen10 joined
TimToady so maybe we just need a HashBlock of some sort that transmutes to a Hash when you put stuff in it 20:08
sorear we already have that situation, the builtins are syntactical statement_prefixes 20:09
TimToady yes, I think about that from time to time too, and wonder if there's a way to fix that so that listops can override builtins 20:10
the grammar is not as unified as it could be on that 20:11
some way of treating grammar rules that look like listops as in the same namespace 20:13

TimToady at the moment, requiring if() is probably good enough, and more than other languages provide
no, the outer one is the special syntax we already have
!
OUTER::<if> would be statement_prefix:if 20:17

kudo/nom: d707ddf | jnthn++ | src/Perl6/ (3 files):
Pull the entire assertion:name handling into Rakudo by overriding the one in P6Regex. Clears up a hack from this morning's patch. Also make it possible for /<x>/ to call a lexical regex x { ... }; it's a compile time decision.

Run three more test files.

benabik That's not a good tag line: "Rakudo Star, now with less Pie"
jnthn masak: It tries to use some trait that doesn't exist
masak huh!
jnthn masak: I didn't dig any further
masak ok.
sounds eminently fixable, though.
jnthn I may in a moment. Just one this in a state where all the stuff in it works. Adding more working stuff in is fine from that.

bbkr1 do we have any working HTTP standalone server? except HTTP::Easy and HTTP::Server::Simple as both are broken when it comes to multipart request reading 23:48

bbkr1 this silence means "no, you are stuck with PSGI" :) 23:49
jnthn bbkr1: I think HTTP::Easy is the most maintained one of those, so you could file a github issue about it there. 23:51
