TimToady there will always be those who think Martin Luthor went too far, and those who think he didn't go far enough. :) 00:00
ab5tract nice analogy :)
TimToady well, the postmodern term would be "narrative"...
pmichaud "story" is better. 00:01
TimToady less threatening :)
narrative is a power word for people who think that postmoderns should exercise power over all other power structures
pmichaud that's not a very good story. :-) :-) 00:02
TimToady nevertheless, you're soaking in it. :)
it's the spirit of our age
ab5tract ha. and i thought it was a power word to disentangle and disempower power structures
(yes i'm being both facetious and serious at the same time) 00:03
pmichaud also the spirit of our age. 00:04
ab5tract :)
sarcasm: the cause of and answer to all life's confusion
TimToady that goes without saying/you can say that again
00:05 plash_ left
ab5tract so was there a project to write perl 5 in parrot? i could see it being useful. 00:07
s/write/compile/
wknight8111 There was, "Punie", i think it was called
ab5tract thats perl 1 iirc
wknight8111 whatevs, there was a project for it
I'm too bad with names to remember what it's called
ab5tract yeah, i was thinking it was something like that too. 'ponie' maybe. 00:08
pmichaud ponie 00:09
ab5tract which would make for the following: punie, pynie, and ponie.
pmichaud I keep thinking I might write a p5-like translator for parrot, just to see how far we can get.
(_after_ we're much farther along on p6, though)
ab5tract right. seems like the opposite of necessary atm 00:10
TimToady first concentrate on APL to p6 :) 00:11
(not so farfetched these days...) 00:12
ab5tract p6 is fully unicoded correct? so i could technically use kanji for method names, etc
TimToady certainly
ab5tract nice :) 00:13
TimToady perl6: sub 名前 { say "moshi moshi" }; 名前(); 00:14
p6eval elf 22530, pugs, rakudo 31766: OUTPUT[moshi moshiā¤] 00:15
pmichaud they all seem to agree :-)
TimToady wow, they all worked
00:15 smg left
pmichaud I'm a little shocked, also. 00:15
ab5tract cool. what're those numbers and why does elf have a different one?
pmichaud I was a bit concerned about rakudo.
ab5tract: svn revision numbers
ab5tract smacks head 00:16
TimToady std: sub 名前 { say "moshi moshi" }; 名前();
pmichaud I tend to stick an 'r' in front of the revision numbers :-)
TimToady is there a stdbot?
p6eval std 22530: OUTPUT[parsedā¤]
TimToady ooh, there is
pmichaud we use it a fair bit these days :-)
it tells us what works and what doesn't. For example.... 00:17
std: sub a { say 'oops'; }; say a ~~ Sub;
p6eval std 22530: OUTPUT[parsedā¤]
pmichaud unfortunately, last I checked, that parses as two prefix:<~> operators, though :-) 00:18
TimToady as it should
since a is a listop
pmichaud correct.
it just catches a few people off guard :-)
TimToady but we should probably catch that one with a warning
since there's no good reason to stringify twice 00:19
pmichaud shouldn't be too difficult to catch that.
I even wondered if it's worthwhile to define prefix:<~~> with a warning.
TimToady I'd fix it right now, but I'm still debugging the damage from the new ~
well, that's how I'd probably do it
pmichaud I like the new ~, but the syntax is a little funky 00:20
probably just takes a little getting used to 00:21
I definitely like it better than [ ')' || fail ]
ab5tract whens the next state of the onion? i've been feeling restless 00:23
TimToady probably won't publish this year's since it was a tech talk/demo of STD.pm 00:24
ab5tract awww... maybe video ? 00:25
its not a year without a new onion address
TimToady well, that's how we'll make the deadline of Christmas This Year :) 00:27
ab5tract in that case this will be a Very Good Year
TimToady like the legislatures that stop the clock at 11:59 so they don't violate the law on getting a budget passed by Octember 35th... 00:28
ab5tract haha. diabolic 00:30
00:30 kanru left
ruoso needs to accept the idea of learning haskell... :/... it's a shame that I can't modify M0ld... 00:39
TimToady haskell is easy to learn. I've done it several times already... 00:43
ruoso I look at the code and it's simply meaningless to me... 00:44
00:45 ab5tract left
Kitchy I almost decided to learn Haskell last week. I wanted no oo and good text processing. If it was more mainstream I'd learn it. 00:46
TimToady I can read it, I just can't write it. Well, I can, but I always get into a losing argument with the compiler...
00:48 xuser joined 00:50 ywc joined
ruoso considers workaround'ing haskell... 00:54
TimToady, have you ever thought on a identity test for the representation of the object? 00:55
like... $obj <something> p6opaque
TimToady surely something that could be returned by reflection without a special operator 00:57
Kitchy Am I the only one who misspells variables named "text" as "test" way too often? 00:58
TimToady I can never type "per" without adding the l :)
ruoso hehe

Kitchy Could someone give me a clue about what challenges were posed to Perlmonks in the past regarding Perl 6? 07:19
Someone mentioned that yesterday.
I'd like to look up those posts on Perlmonks. 07:20
moritz_ the only challenges I know of were implementing some piece of code in various languages, including perl 6
maybe google for site:perlmonks.org challenge "perl 6" 07:21
Kitchy I'll try. Here's what I'm talking about from yesterday: colabti.org/irclogger/irclogger_log...5,Sun#l226 07:23

moritz_ not quite yesterday, IMHO ;) 07:28
Kitchy: pmichaud's "sure, I've invited that in the past. It'd be good to do it again." was about offering an entry in the CREDITS file, not about previous challenges 07:29
Kitchy Yeah. I found his two posts on Perlmonks and they're not challenges. 07:30

pmurias, I was wanting to add a test for the RI of an object... 09:41
pmurias, to test in a signature if the object is a native int
for instance...
09:41 sri_work joined
pmurias so you want to have a compare RI opcode 09:45
?
ruoso yes 09:53
so I can write the ACCEPTS code for a :(int, int) signature

typoes--
moritz_ TimToady: should $0, $1 etc work inside closures of the Str.trans method?
ruoso will try to re-read then 17:23
pmurias, do you think a RI identity operator would mean knowledge about "internals"?
pmurias what i meant is that m0ld can't access the internals of an object in a non-polymorphic way so it has no business of inquiring how are they implemented undearneath 17:24
17:24 Bzek left
pmurias ruoso: it's not very usefull to inquire how an object is implemented withought being able to use that knowledge 17:25
ruoso pmurias, well... it actually is, in the case of signatures...
pmurias, it serves to know if we have the type of objects the code knows how to deal with
(not type, but repr) 17:26
considering it will eventually go to native C code...
checking for the correct repr before going to the native C is a good idea
then the C code can use the knowledge about the internals
pmurias in a mixed C/m0ld scenario it makes some sense 17:27
pmurias is eating his dinner so is not very responsive 17:28
ruoso pmurias, the case here is about &infix:<+> for instance... in the :(int, int) variant, it goes straight to C code 17:29
pmurias ~~ could know about RI's 17:30
ruoso I thought about it, but &infix:<~~> is also a sub... so we need a circuit-braker 17:31
moritz_ ~~ is also a macro (don't know if that matters right now)
17:31 ab5tract joined
pmurias we can use RI.isa or something else but i don't want to use a uncommonly used operation an opcode 17:32
s/uncommonly/one which can be expressed with other opcodes easily/ 17:34
17:34 abra joined
TimToady moritz_: if the match sets the $/ in trans's body and then trans calls the closure, I'd think probably yes 17:35
moritz_ TimToady: ok, thanks 17:36
17:37 mberends joined
pmurias ruoso: a simple &RI_is could be better than a isa method on RI's 17:38
pmichaud TimToady: so, 'foo'.trans(/(.)/ => { ord($0) }) the $0 doesn't refer to the $/ of the surrounding block? (i.e., the block containing the .trans method call itself)? 17:39
ruoso pmurias, well... I even thought about creating an object that would do the test...
but it maybe would be simpler to just test in mold
pmurias i can write &RI_is 17:40
TimToady pmichaud: I think a block's $/ is initialized with it's CALLER::<$/>, not OUTER::<$/>
pmichaud checks. 17:41
ruoso pmurias, you mean create a new object? or as a syntax in mold?
pmurias, I even have the test for it already...
pmichaud ($/ initialized with CALLER::<$/>) I think that's different from what was discussed earlier. so, $_ is from OUTER, but $/ is from CALLER? 17:42
ruoso pmichaud, remember that most of the time where $/ would be used CALLER and OUTER are the same thing... 17:43
pmichaud ruoso: TimToady and I had a very specific discussion about this a few months ago. 17:44
TimToady alternately, when you have a construct like /(.)/ it labels it with the current $/ for it to set.
could be made to work either; not sure which is better
pmichaud TimToady: so, in $foo ~~ $regex we end up setting the $/ of $regex as opposed to the current $/ ?
pugs_svn r22536 | ruoso++ | [smop] sketch for the test on checking RI identity 17:45
ruoso pmurias, check test/38
TimToady maybe. the OUTER solution is likely more efficient, but I may be imagining things
the CALLER solution would propagate inward as long as trans doesn't do its own matching, which is maybe a problem 17:46
17:46 pmurias_ joined
TimToady maybe $foo ~~ $regex can set multiple $/ 17:46
the current one and the closurely one 17:47
ruoso .oO( wasn't $/ declared as "my $/ is context<rw>" on every routine, and regex set it by accessing $+/ ? )
moritz_ S02 says that $/ is always contextual
TimToady basically, /(.)/ is more like {/(.)/} if we go with OUTER
moritz_ so that would default to CALLER::
17:48 pmurias left
TimToady that means that you *can* refer to it via CALLER, not that you must 17:48
OUTER::<$/> is also a valid way to refer to a particular $/
pmurias_ ruoso: something like the test but with 'postcircumfix:( )' instead of 'check'
ruoso yeah... you're probably right... 17:49
TimToady the question is what will be dwimmier
ruoso pmurias_, does the RI DSL knows how to deal with singleton RI's? 17:51
17:51 justatheory_ joined
pmurias_ not yet 17:52
17:52 justatheory left
ruoso pmurias_, should I write it in C? or would you change the DSL to support that? 17:52
pmurias_ i think we should use CCode 17:53
pugs_svn r22537 | lwall++ | [STD] cascaded arglists fail to allow closure as first arg
TimToady pmichaud: what's your feeling about the relative overhead of initializing $/ with CALLER vs OUTER? 17:54
pmichaud they're about the same in Parrot land 17:55
ruoso pmurias_, instead of a singleton specialized RI?
pmichaud the other context and the caller context are basically one pointer reference away -- it just depends on which pointer.
s/other/outer/
TimToady well, a user can always get at caller via $+/ or whatever
pmurias_ ruoso: yes 17:56
TimToady so I'm inclined to go with outer, but that breaks your trans unless we closurize /(.)/ to grab the current $/
ruoso pmurias_, that should be ok...
pmurias_, that means it won't use the RI DSL... 17:57
pmichaud (closurize /(.)/) does that then mean that any use of the regex would affect the $/ of the block where it was defined?
that sounds... icky. I had been thinking that only smart match set $/ 17:58
TimToady I suppose {/(.)/} naturally does the right thing, since it would initialize $/ to OUTER
pugs_svn r22538 | pmurias++ | 38 should use .()
TimToady or {$_~~/(.)/} if that's so
pyrimidine pmichaud: that's how .match is implemented currently (you get a Match object, but $/ is not set)
pmichaud pyrimidine: yes, I know. 17:59
$foo = $bar.match(/whatever/) didn't seem to me to automatically imply setting $/
pmurias_ ruoso: \
sorry typo
TimToady well, that tends to push us toward CALLER init instead 18:00
esp if we want .subst to work as documented
pmichaud I don't have any particular heartburn with $/ as CALLER (but haven't thought about it much)
I had been lumping $/ with $_ and $!, but that doesn't have to be the case. 18:01
and, of course, I had originally misconceived $_ to be based on CALLER.
pmurias_ ruoso: who is supposed to be implementing RI test now?
TimToady well, $! also has CALLER semantics, though not on init
18:02 zamolxes left
TimToady $_ is CALLER if the caller passes it as a param 18:02
and OUTER otherwise
pmichaud right.
ruoso pmurias_, I'm doing it ...
TimToady maybe $/ is similar? not sure how that'd work...
pmichaud so they all somewhat act like CALLER, except that $_ is special in that it's the default for $_
er, for -> $_ = OUTER::<$_> { ... }
TimToady fail sets $! in CALLER, for instance 18:03
pmurias_ stops implementing ri test 18:04
pugs_svn r22539 | pmurias++ | [smop] removed old mildew AST definition 18:06
TimToady or we could just go with straight OUTER and force the user to say $+0, $+1 to get to their caller's $/ on trans. I doubt it would be a FAQ 18:08
but that doesn't help much with .subst
pmichaud it came up with .trans on #parrot, fwiw.
TimToady which probably *would* be a FAQ
the alternative would be for .subst and .trans themselves to tweak CALLER::<$/> which would then be visible as OUTER::<$/> in the closure 18:10
maybe that's the correct solution
and .match (and then ~~ has nothing to do with it)
that feels like the $! solution, and that gives me warm fuzzies 18:11

ruoso just hit the "postcircumfix:<( )> signature" issue again! 18:12
TimToady The signature hits back!!! --more-- 18:13
pyrimidine if a transliteration has multiple regexes?
pugs_svn r22540 | ruoso++ | [smop] ritest in place... but now I hit the "postcircumfix:<( )> signature" issue again! 18:14
TimToady the binding of $/ only has to last till the closure is called
moritz_ then the one that matches (the longest token) should set $/
pyrimidine okay
moritz_ (at least that's my limited understanding)
TimToady probably need to compose all the regexen into a single alternation anyway
so the LTM can have at it 18:15
ruoso TimToady, since method is an object, the actual postcircumfix:<( )> cannot have the :(|$capture) signature, because it needs the actual method object as the invocant of that call...
TimToady :($self: |$capture)
moritz_ TimToady: speaking of regexes and captures, I don't think that the current split() semantics are useful... 18:16
ruoso TimToady, hm?
TimToady you can pull off the invocant and then bind the remaining to $capture
pmichaud (subst/trans) - I agree... I came up with the same answer as I stepped away from the desk. So, .trans and .subst set CALLER::<$/> after each match. Clean.
moritz_ TimToady: currently they say that if the regexes has captures, the match objects follow in alternation with the strings between the matches...
ruoso TimToady, right... but on a method, we need a real invocant...
moritz_ TimToady: but the question if a regex has captures isn't determined at (regex) compile time
ruoso if we pull the invocant off, how is it going to find "self" 18:17
moritz_ TimToady: what about having an :preverse named arg that switches between two modes of operation?
pmichaud ....:perverse?
ruoso stands for postcircumfix:<( )> ($capture) instead
moritz_ erm, :preserve
*blush*
TimToady if you call the method as a sub it can just use the next arg as invocant, if you unshifted the method object
moritz_ well, the name isn't good 18:18
TimToady ETOOMANYTHREADS
moritz_ TimToady: should I take it to the list?
TimToady switches context
ruoso TimToady, but that requires transformations in the capture... is there a reason for avoiding the actual capture as the first positional argument for postcircumfix:<( )> ? 18:19
TimToady moritz_: whether a regex has captures *is* determined at compile time
if not, we've botched the design
moritz_ TimToady: (.)* doesn't produce a $0 if it matches with zero count 18:20
TimToady ruoso: that would work too, I suppose
moritz_ TimToady: so it is only determined if it has the *potential* to create captures
ruoso TimToady, but I mean, can I consider adopting it? since my methods and subs are already objects... it's pretty hard to implement the other way... 18:21
TimToady it makes $0 that is an empty array
ruoso: sure, that's fine
ruoso cool
moritz_ oh, right
moritz_ must have confused something very badly 18:22
TimToady: so never mind, thanks for the clarification
pmichaud PGE currently has trouble with /foo || bar (.)*/ in that $0 isn't created as an empty array if we match 'foo'.
speckbot r14589 | larry++ | various tweaks and clarifications 18:23
pugs_svn r22541 | pmurias++ | [mildew] added some ast creation helpers, because the Moose constructors are too verbose 18:24
TimToady ruoso: have revised S13 to $capture
ruoso :D
TimToady, thanks!
TimToady finally back to parsing 100%!!! whew!!! 18:25
18:26 justatheory_ left, justatheory joined 18:32 alester left
pyrimidine Are we leaving .match as is? (not setting CALLER::<$/>) 18:32
moritz_ is there a god reason for 'make' to clean the lex cache *after* compiling itself? 18:33
s/god/good/
TimToady .match will also set CALLER::<$/> 18:34
moritz_: no, was just thinking about that myself
in terms of "if I just want the gimme5 to run, what if I ^C in the middle of the rm?" 18:35
pugs_svn r22542 | pmurias++ | [mildew] added missing file 18:36
TimToady feel free to rearrange
moritz_ allright 18:37
TimToady next thing is to add flags to viv such as --ast and --p6, though I think --p5 is maybe default, since that's the name, vi-v 18:39
maybe we should rename Perl 6 to vi :)
pugs_svn r22543 | ruoso++ | [smop] signature for postcircumfix:<( )> is now :($capture) instead of :(|$capture). All tests pass, ritest works, now lets move to multi sub! :)
TimToady then we could have vi vs Python wars :) 18:40
pmurias_ vi(m) uses ex as it's scripting language which is disgusting
ruoso .oO( on the bright side, at least it's not emacs lisp )
PerlJam pmurias_: as "a" scripting language. You may use others I'm pretty sure. 18:41
Hmm. I wonder if we can get parrot embedded in vim :)
pmurias_ ruoso: ex is worse than emacs lisp
ruoso that's hard to imagine 18:42
TimToady hey, no four-letter words please
ruoso not even "perl"? 18:43
TimToady Perl 6 is a six-letter word, kinda sorta 18:44
pmichaud still only sees four letters, a space, and a digit.
fullermd Well, it's two words. So on average, it's a 2-letter word. 18:47
ab5tract hahaha 18:48
pmichaud or a 3.5-letter word
TimToady or a 2.4-letter word
like the average family 18:49
pmurias_ the vim perl api seems to be better than i remembered 18:50
TimToady Wagner's music is better than it sounds
ruoso .oO( well, at least it is not just my brain that is melted... ) 18:51
TimToady you're melting as a whole? 18:53
18:58 ispy_ left
[particle] Perl 6 is a single utf-256 character 19:04
moritz_ let's hope it neer becomes a wtf-257 char ;)
pmurias_ anyone got a link to Jonathans blog entry on how he implemented mmd? 19:05
[particle] google://rakudo.org ;)
TimToady it's probably an NFG character :)
ruoso TimToady, btw, "Last Modified" in S13 has the wrong year 19:06
speckbot r14590 | larry++ | wrong year, ruoso++ 19:07
TimToady oh wow, got about twice as much hot sauce as usual. and when you're talking 550,000 scovilles, that's a real brain melter 19:09
don't think I'll get anything done the rest of the day, except rewriting Xanadu 19:10
ruoso heh
ab5tract hehe 19:11
TimToady *both* of them
19:11 [particle] is now known as [particle-split]
ruoso perl6: multi foo(Int $a) { say 1 }; multi foo(Num $a) {say 2}; foo(1); foo(1.1); 19:13

ab5tract unicode is yummy
19:26 azawawi left
ruoso TimToady, is it sane to assume that in dubious cases like the one above, the behavior is undetermined? or is there a left-to-right precedence in multi variant ordering? 19:27
19:29 azawawi joined
pmurias_ ab5tract: elf actually runs on perl5 19:34
19:34 silug left
pmurias_ it uses ruby only for parsing 19:35
ruoso: you get an ambigiouity error 19:36
ruoso by spec? 19:37
pmurias_ think so can find the place where it's specced 19:40
re postcircumfix:<( )>, it's possible to use a subroutine as a method with the invocant being passed as a positional 19:41
ruoso pmurias_, that would require transforming the capture...
pmurias_ S12:278
19:42 pmurias_ is now known as pmurias
pmurias ruoso: that would point to having both postcircumfix:<( )>($capture) (perhaps under a different name as CALL) and postcircumfix:<( )>(|$capture) 19:44
ruoso pmurias, actually... not really 19:45
pmurias, if you look a little bit below, it will show another example...
where it uses an anonymous methdo 19:46
that second example requires postcircumfix:<( )>($capture)
19:46 Lorn__ joined
pmurias read the paragraph underneath? 19:47
ruoso pmurias, I think the upper example counts on method-to-sub fallback
azawawi moritz_: a couple of tests like chomp.t is using is_deeply (Test::More). I cant find it in languages/perl6/Test.pm
pmurias what would my $method = method ($a:$b,$c) {say "a:$a b:$b c:$c 19:48
moritz_ azawawi: yes, that's a problem
pmurias "};$method(1,2,3)
print?
ruoso it would probably fail because of a missing invocant and too many positional arguments 19:49
azawawi scratching his head
moritz_ azawawi: there is quite some confusion at the moment. Some tests seem to assume that is() uses infix:<eqv> comparison, most assume string comparison 19:50
azawawi: so we haven't yet decided what to use. If is() uses eqv, then there's no need for is_deeply, because is() will do that job
ruoso pmurias, it was the method-to-sub fallback that used to transform the capture, moving the invocant to the first positional argument... but that is no longer the case... 19:51
pmurias TimToady: what do you think of having a t/uncertain directory where we could place tests you could give an official verdict on when you have some spare time?
ruoso: so you think it's a relict in the spec?
ruoso maybe...
btw... your example wouldn't fail...
pasteling "azawawi" at 212.38.154.121 pasted "List of tests using is_deeply" (66 lines, 5.3K) at sial.org/pbot/32512 19:52
ruoso actually it would... but just because of too many positional args, not because of missing invocant
azawawi moritz_: so replacing them with is() will do the trick
moritz_ azawawi: only if is() actually should do "smart" compaarison.
azawawi: that's the point that's not yet decided
azawawi moritz_: ok 19:53
moritz_ the ones in hyper.t seem fairly non-sensical to me
is_deeply(~@r, ~@e, "distribution for unary prefix");
ruoso pmurias, but one thing I know for sure... the "turn the invocant into first arg" thingy was part of the "method-to-sub fallback"
pmurias ruoso: As a convenient form of documentation, such a closure may also be written
in the form of an anonymous method
moritz_ why the bloody hell do you first convert to string, and then compare the strings deeply?
PerlJam moritz_: that is craziness. 19:54
ruoso wonders how many dimensions strings has
PerlJam perhaps someone thought ~@a meant ~@a[0], ~@a[1], ~@a[2], ... 19:55
pmurias ruoso: that seems to imply an anonymous method is merely a different way of writting an anonymous sub
ruoso pmurias, not really... it implies that you need to have a method if you want to make a method invocation...
moritz_ PerlJam: probably cargo-culted crazyness 19:56
azawawi looking for something to work on
ruoso pmurias, the key thing here is that "$obj.$method()" requires $method to be a method 19:57
pmurias or a Code
ruoso pmurias, because there isn't a 'method-to-sub' fallback anymore
pmurias, that's the part I thing is relict
*think
19:57 Lorn left
ruoso because it's an anonymous implementation of the 'method-to-sub fallback' 19:58
19:58 alester joined
pmurias it's pointless to discuss it futhermore atm we must now wait for a clarification from TimToady... ;) 19:58
pugs_svn r22544 | moritz++ | [t/spec] tests for Str.trans with regex and closures. One failing on rakudo
r22544 | moritz++ | (RT #59730).
TimToady it really has little to do with fallback, and much to do with the fact that references are untyped, &foo could be either a sub or a method 19:59
ruoso TimToady, so it will send the capture unmodified?
TimToady I think a method object can fake up an invocant if its capture is missing one, and I think a sub can treat an invocant as a first positional if the capture contains an invocant. 20:01
this is independent of whether the dispatchers fallback
but rather the basis for writing dispatchers
ruoso TimToady, so the default signature is different...
