diakopter sorear: did you get STD running? 00:43
JimmyZ \o 01:23
morning 01:24
diakopter hi 01:25
lue afk 01:27
sorear diakopter: I've had STD running for a while 01:30
diakopter ok 01:30
diakopter std: my $a = (Array[int]).new # mruhahaha 01:42
p6eval std 30541: OUTPUT«ok 00:01 108m␤»
diakopter though to be more accurate... hrmph. I guess I should use List[int], since that's what's underneath it anyway. 01:43
boo.
diakopter oh yeah. 01:45
I forgot I already created an alias for that.
sorear grr. STD.pm6 relies on slangs to parse quasiquotes 01:47
diakopter was aware of that, once upon a time. 01:48
sorear diakopter: I have macros working 01:56
diakopter I saw :) your work rocks 01:56
sorear I just need hygenic quasiquotes now for maximum impressiveness
which is not as ridiculously hard as I first beleived
diakopter someone needs to give you a commitbit 01:57
(not I, since I can't) 01:58

colomon dang it, should have gotten that one in before jnthn went off-line for days. :( 02:02
diakopter where'd jnthn go
diakopter feels nosy 02:03
colomon He's camping in Iceland.
sorear colomon: don't you have commits too? 02:05
colomon yes. 02:06
but I don't have the first clue about dealing with signatures. that's jnthn's area.
diakopter boo. googlecode rejecting my svn ci.

sorear heh, it does work in p6eval
diakopter o__O 02:15
sorear diakopter: Yes, the compiler API is exposed to Perl 6 code. 02:23
Isn't it wonderful?

sorear has some misgivings about the specced design of hygenic quasiquotes 02:58
sorear most importantly, unquotes being a kind of term 03:07
so you can't do stuff like declare functions with variable names
I'd like to wait until someone has a use case before doing much hygiene hacking 03:08
sorear another problem revolves around lexical binding 03:18
lexicals are bound to a specific environment at parse time
so quasi { my $COMPILING::x = 2; {{{ $ast }}} } doesn't really make sense
because $ast already has lexicals bound
sorear I think what we need is to divide macros into two groups 03:39
1. Category macros (like Lisp's reader macros) are associated directly with a grammatical category. The 'is parsed' is combined with <sym> to make a new protoregex rule, which is injected into the grammar; user code is run when the grammatical rule is recognized. 03:40
1. Functional macros (like Lisp's syntax macros) involve no special syntax; they do not modify the grammar. However, when a function call (including operator syntax calls like x ~ y === &[~](x, y)) is going to be generated, the AST construction is redirected and calls the macro instead. 03:42
s:2nd/1./2./ 03:43
sorear returns to his real code and tries to pretty it with macros
cognominal I can't find where nibbler is defined :( 04:18
lue wonders if there's a neat little linux program to search the human genome. 04:24
lue (firefox doesn't count) :)
sorear grep 04:28
lue I searched the fedora package repos for 'genome', and came up with a couple things (including a few P5 modules. figures :) ) 04:33
sorear contemplates adding roles to NQP-rx 04:46
cognominal I don't understand. I find nibbler in P6Regex::Grammar. So how rakudo can work if it is not pulled as the parrot in rakudo? 04:48
sorear Failed to parse sentence 04:49
if we had roles in NQP, we could do proper slangs, and lexically scoped macros, and other such stuff
cognominal I mean. rakudo does pull parrot to compile. how come I don't see nibbler
sorear Where are you looking and what do you want to find? 04:50
rakudo: 2 ¢ 3
p6eval rakudo c4857a: OUTPUT«Confused at line 11, near "2 \x{a2} 3"␤current instr.: 'perl6;HLL;Grammar;panic' pc 500 (ext/nqp-rx/src/stage0/HLL-s0.pir:328)␤»

p6eval rakudo c4857a: OUTPUT«Could not find sub &infix:<¢>␤current instr.: '_block21' pc 29 (EVAL_2:0)␤»
cognominal as I said nibbler is in P6Regex::Grammar of nqp-rx
sorear operator injections are not lexically scoped 04:51
I wonder if there's a spectest for that
cognominal how come I don't see it when I do a ack on rakudo (which includes a parrot/ folder)
sorear parrot/ is not a parrot source tree
parrot/ is bits specific to the Rakudo Parrot backend 04:52
(currently the only one)
note that Perl6::Regex is a subclass of Regex::P6Regex::Grammar and inherits the nibbler method
cognominal ok, I thought it was a copy of some parrot branch.
sorear no, it only has four files 04:53
cognominal ??
sorear unless you're talking about the automatic checkout
cognominal yes
sorear but P6Regex isn't part of Parrot anyway
cognominal I see P6Regex-S0 that must be generated from Regex::P6Regex::Grammar 04:54
so I am surprised to see that file and not the file that is used to generate it 04:55
sorear yes
the parrot repository contains files without matching source code
cognominal that's what puzzles me.
ok. I suppoed the contrary :) 04:56
sorear github.com/perl6/nqp-rx/blob/40bb2a...Grammar.pm
P6Regex is implemented using P6Regex
so you need to start with a precompiled version
Parrot ships the compiled version, but the canonical source is in a different project 04:57
there are 4 major subsystems here
cognominal ...in the nqp-rx branch
sorear not a branch, it's an entire project 04:58
cognominal indeed.
sorear 1. Parrot, a VM. Parrot is shipped as C source
2. PCT, a library for compiling to Parrot bytecodes. Is written in Parrot assembly and shipped along with Parrot
3. NQP-rx, a very simple Perl6-like language for Parrot + an implementation of Perl6 parsing rules. It is written using NQP-rx (for the frontend) and PCT (for the backend). It is shipped *as binaries* with Parrot; the source lives elsewhere 05:00
4. Rakudo, an implementation of full-ish Perl6 on top of NQP-rx and PCT
cognominal " nqp-rx : It is shipped *as binaries* with Parrot; the source lives elsewhere" : now everything makes sense to me. thx 05:01
sorear The first big item on our post-R* agenda is to loosen Rakudo's ties to PCT 05:02
NQP is very simple, it can be easily implemented on other platforms (nq-nqp and purlesque are active projects in this direction) 05:03
PCT is pretty deeply tied to Parrot
cognominal well, only the pir generation part. The rest is written in pir but could be rewritten in nqp/perl 6 rakudo once the bootstrapping done. 05:06
lue afk and goodnight! 05:10
sorear I don't think parrotfolk would like that very much
having a core library (PCT) depending on a non-core component (NQP-rx)
JimmyZ I think it's more easy to get more contributors. 05:14
oldy hi, 06:22
Looking at fedoraproject.org/wiki/Features/Rakudo_Perl_6. Can Perl6 be installed on Fedora machine, without disprupting existing Perl5.already installed? 06:24
araujo of course oldy 06:28
the most popular implementation right now is rakudo ... you install that even in your home dir, set a path for the binaries, and ready to go
sorear Perl6 is installed as perl6 06:31
we aren't even attempting to take over perl5 yet
araujo sorear, we will right?, 06:33
oldy araujo: & sorear thanks, will give it a go :) 06:38
snarkyboojum FWIW, I think quite a few respected perl5 and perl6 guys have been expending effort to dissolve the 'take over perl5' meme 06:41

sorear TimToady: Would you characterize :actions as a fossil? 07:25
sorear huh. perl6.vim parses "is parsed" but not "macro" 07:39
moritz_ patch it
sorear How is ./perl6 --target=past spelled these days? 08:34
moritz_ NYI, I fear 08:35
sorear so I'm just hallucinating that it worked in the past? 08:37
moritz_ I'm sure it worked in alpha
sorear writes a script to emulate the behavior
I've never used alpha
I might be thinking of nqp though
(would anyone like a copy?) 08:40
moritz_ of what? 08:41
sorear a script that emulates perl6 --target=past
moritz_ would prefer a patch
sorear that would involve me understanding what's wrong 08:42
the bug doesn't make any sense since AFAICT --target=past is a PCT feature and other PCT compilers work
moritz_ I'll try here once my rakudo build is finished
works here 08:44
sorear: there's a known bug... you can't mix --target= with -e
sorear --target=pir -e works fine 08:45
--target=past -e generates no output
moritz_ now that's weird
sorear moritz++ perl6 --target=past <( echo 'foo' ) #works fine 08:46
cognominal --target=parse -e does not generate any output either 08:49
sorear What's idiomatic Perl6 to disambiguate " $varalphanumsafter " ? 08:54
moritz_ "{$var}alphanumsafter" 08:55
though we're all new to Perl 6, more or less, so I'm not that sure with idioms 08:56

moritz_ maybe it backtracks over the ;
sorear most importantly, why are only the first three letters of the error message getting used?
moritz_ huh?
sorear er 09:09
first three letters of the module name
moritz_ I think the length of code quoted in the error message is limited 09:11
sorear the actual error was quite simple - I forgot to 'make install' my macro-aware rakudo before trying to write code using it
moritz_ which is quite sensible, but maybe the limit itself is a bit too tight
sorear so would a "grammar backtracks too far generating error" bug be valid? 09:13
is it possible to search the perl6 rt queue? 09:14
moritz_ it is possible, the I don't like the search interface at all
sorear I only see an option for searching the perl.org rt instance, which is less than helpful for things that affect both 5 and 6
moritz_ (and you might need to log in to get to the advanced search)
sorear sent 09:19
moritz_ sorear: just read in the backlog about your idea of a streaming PAST model 09:20
I like it
but I don't know how much of it can be used in rakudo
because rakudo will have to do additional passes over some intermediate format (don't know if that will be PAST or not) 09:21
sorear "will"?
what NYI feature requires reprocessing PAST?
moritz_ to determine sink context, and check routine names at CHECK time

moritz_ this error message could be awesomized in several ways: 09:43

sorear if it was going to be completely awesome, it should also be spelled "Role-required methods are NYI in Rakudo"
moritz_ I don't know what "Role-required" means 09:46

JimmyZ ;)
masak JimmyZ: I don't know if it works in Perl 5. does it matter?
Perl 6 has its own way of handling these things, clearly explained in S02 and S04.
JimmyZ wonders why it works in Perl 5 and why it doesn't work in Perl 6, and what wrong with Perl 5 is about it 10:49
masak in Perl 5 'our $a = 1; { say $a; our $a = 2; say $a; my $a = 3; say $a }; say $a' prints 1\n2\n3\n2\n 10:51
and it also gives one warning about a redeclaration and one about variable masking.
I can think of two sane things that might happen in Perl 6. 10:52
either it dies, because the user is obviously confusing herself.
or it lives, and the variable in that block behaves like an 'our' variable.

masak :)
snarkyboojum forgive the debugging output :|
masak no prob. nice to see things falling into place.
I still think pretty-printing could look something like this: gist.github.com/372419 11:00
snarkyboojum I wish I had read your gist before trying to integrate :) as I ended up reinventing something like Yapsi::Runtime::get-value-of
so threw that out and uses your (more correct) method
s/uses/used/ 11:01
masak yeah, I put that one in Yapsi::Runtime because it seemed it would be duplicated.
I also think we should invent the commands 'follow $a' and 'unfollow $a', to make some values print automatically ever time the user changes ticks. 11:02
snarkyboojum masak: cool, something like watch
masak yeah.
maybe that's a better name.
'watch' and 'unwatch'.

masak which is the root of the problem.
moritz_ agreed
moritz_ after having fought with my own HTML + JS templates for my slides, somebody pointed me to meyerweb.com/eric/tools/s5/ 11:31
which looks nicer than what I have now, although my solution now works
moritz.faui2k3.org/tmp/talk/0000.html 11:32
masak S5 is indeed nice. 11:33
moritz_ I kinda like their FAQ, too
Shouldn't it really be the "stupendously simple small sized standards-based structural slide show system", or S9? That would be nearly twice as good as S5, right?
Let's not get carried away.
masak :)

snarkyboojum masak: why does alpha say it's a pair, and rakudo say it's a hash? a pair is only giving me one element in the hash presumably? 11:38

snarkyboojum I want alpha to treat that as a hash
moritz_ a hash in list context behaves like a list of pairs

(probably old news to people like arnsholt_, but I found it quite interesting) 13:46
colomon moritz_: funny thing was, I saw that headline immediate after seeing ESR mention how nice the speech recognition feature on his Android phone was.... 13:47
arnsholt_ moritz_: You know how it is. It's hard to wreck a nice beach/It's hard to recognise speech =) 13:48
moritz_ colomon: and it does work quite well, for limited applications like controlling a phone
colomon moritz_: actually the context was how (almost?) any text field could be filled using speech recognition. 13:49
moritz_ cool if it works :-)
colomon "Much more impressive in practice is the fact that voice-to-text now works on any text input box, rather than being a browser-only feature. It’s not perfect – you’ll get the occasional funny homonym – but it’s good enough to reduce the amount of typing I have to do really significantly, and the background-noise cancellation works remarkably well. I’ve grown used to having it work even in the hubbub of a crowded convention
esr.ibiblio.org/?p=1961 but that's all he says about that. 13:50
I don't know how true it is, but it was very funny in conjunction with the other article's headline. :) 13:51
moritz_ somehow that reminds me of "Perl is dead" - "Perl is alive and kicking" :-) 13:52
arnsholt_ The section about statistics is interesting (and to my taste)
arnsholt You can get some quite interesting results with statistical models, but you only get so far 13:53
Especially, what is the most probable sequence at one level (word segmentation of running speech for example) may very well turn out to be impossible further up in the hierarchy (syntax, semantics) 13:54
moritz_ so you need backtracking 13:57
arnsholt Yeah, I think so. Some kind of interation between the different layers 14:00
arnsholt Also, as he points out in the conclusion, the problem looks increasingly like flat-out AI 14:01

masak Raccurato++ 15:06
colomon I have to admit that working on const-correctness kind of makes me wish we had that for Perl 6 methods. 15:22
masak 'const-correctness'? 15:26
colomon masak: you can (sort of) guarantee a C++ method has no side-effects on the class object it is run on by declaring it "const". 15:27
masak that feels oddly sideways. 15:28
it's not the method that is 'const', it's the things it doesn't do to the invocant :)
colomon: anyway, I could imagine that being done with a trait of some sort. 15:29
colomon it's definitely not perfect
but having the compiler enforce it can be a handy way of clarifying your thinking that Perl 6 lacks.
(but then, if you can define a trait for that, that would be full of awesome....) 15:30
it is one more bookkeeping thing to keep track of while you are programming, but it's mostly second nature to me now. :)
masak it would probably have to involve some analysis of the method body, in order to enforce the constraint...
colomon nods 15:31
masak something like 'the method body may not assign to attributes, or call other methods which don't have the same trait"
colomon the nice thing about that is you could also have the stricter version: 15:33
this method has no side effects.
masak is 'next' a side effect? 15:34
what about looping forever?
colomon heh, there was discussion of looping forever (and the optimization thereof) on Hacker News yesterday. 15:35
masak URL?
colomon news.ycombinator.com/item?id=1310105 15:37
masak ah, I had put that one in my queue. :) 15:39
colomon :)
it's an interesting question.
masak seems the discussion is divided between those who stick to the spec and those who appeal to reality :) 15:41
colomon though I'm inclined to agree with the group who thinks that complicated loops that provably have no side effects in any iteration of the loop ought to be optimized away. 15:42
masak hm, maybe.
colomon sounded to me like a hole in the spec, not really specified either way.

ash_ you can (thankfully) still get to sub a 20:10
guess i should use & more to make sure you can tell what your doing
moritz_ not really
a() should be sufficient
rakudo: sub a { 'a' }; enum A <a b c d>; say a() 20:11

ash_ ah, cool
colomon apparently just slept 20 minutes sitting up in his office chair .
hey, I just realized jnthn is missing #rs this week.
ash_ power nap eh?
colomon perfect time to go crazy. ;)
power nap indeed.
no wonder my mouth was dry.
colomon I thought I was just blinking in and out a bit, but Jen says I snored for 20 minutes. 20:12
pmurias diakopter: hi 21:21
diakopter hio 21:24
lichtkind hai
diakopter pmurias: I'm working on revealing clr generic types to perlesque as parametric types 21:29
diakopter pmurias: also, I got the asmbly_1.exe files to not have a dependency on Sprixel.exe 21:30
(necessarily)
(in mildew's case, we'll want to have mildew_stage0.dll available as a link to both Sprixel.exe's compiler and the resulting assemblies) 21:31
diakopter (so that mildew's resulting assemblies don't need a reference/dependency to Sprixel.exe) 21:31
(unless of course the code they represent contains an "eval('code')" 21:32
pmurias what should mildew_stahe0.dll contain? 21:42
* mildew_stage0.dll
the P6{Str,capture...}?
diakopter yes 21:45
lichtkind what is ORed ? 22:04
TimToady the opposite of ANDed 22:10
lichtkind TimToady: thanks 22:12
TimToady: you got my reaction to your message?
i see now it means or-ed, i read o-red 22:13
TimToady lichtkind: yes, though I sent my message a couple days before you got it :) 22:14
possibly before Damian sent his...
lichtkind TimToady: yes so damian was only virtually faster, but he found some other error too
TimToady: however its fixed now in both version, working on metops and escape sequences now 22:15
lichtkind currently sees he missed the S meta op 22:18

snarkyboojum no 22:52
oops wrong window :)
TimToady yes 22:54
sorear moritz_: I know *exactly* what's causing the lexical var capture bug. 23:14
do I need to put this in the topic or something? ash_ just spent however much time rediscovering it... 23:15
unfortunately
phenny: seen pmichaud
this is a potentially controvertial change; I need to track down the PCT maintainer before I can push a patch 23:16
which is probably going to have to be a #parrotsketch thing
TimToady well, better to ask around on #parrot than here, I suspect 23:17
snarkyboojum rakudo: say e ** pi - pi # backlogging fun 23:21

sorear phenny: tell ash_ - please contact me before raising more heckles over broken closures in PCT. You're duplicating a ridiculous amount of work I did a week ago. 23:25
phenny sorear: I'll pass that on when ash_ is around.
masak ahoy. 23:27
diakopter sorear: disregarding the controversial-ness of your proposed change, I'm curious about the technical explanation
masak I just realized that jnthn++ has put in a first shot at named enums. 23:28
I'm not sure I had registered that before. even though it's not complete, it's great news.
masak and now jnthn has gone underground, which I take to mean that he wants me to round up all the aspects of named enums that still don't work, and package them as RT tickets until he comes back. :P 23:29
sorear You could always help me break macros 23:30
masak oh, gladly.
sorear masak: Sadly, I don't have a newsletter. 23:37
snarkyboojum dobro jutro p6hackers 23:38
masak no jutro here for a couple hours yet... :)
snarkyboojum I thought it was almost 2am there - oh well :) 23:39
masak sorear: then how am I supposed to know about the current state of macro implementation? :)
masak snarkyboojum: it is. could be seen as a very premature jutro, I guess... :) 23:39
but I assure you it doesn't get darker than this outside. 23:40
sorear shrug, I guess you could try github's rss generator
colomon masak: I'm sure he'd be happy if you found the bugs and fixed them instead. ;) 23:40
masak sorear: on what repo? 23:40
Rakudo?
sorear sorear/rakudo
masak ah, excellent.
I will most certainly download it and give it a whirl.
I mean, macros! wow! 23:41
sorear and I found a rakudobug while implementing it!
masak yeah, I noticed :)
sorear++
so, the most recent work is in topic/macros? 23:42
sorear yes 23:43
heh, I found a wrong spectest
S06-operator-overloading/sub.t 155 'my' needs to be 'our' 23:44
masak why? 23:45
sorear because my subs don't live in namespaces 23:46
so &::(...) is wrong
masak ah, indeed.
TimToady well, but symbolic indirection is supposed to look in lexpads as well 23:47
masak so 'my' is not wrong?
TimToady looks pretty okay to me, assuming the & migrates in to the actual lookup 23:49
but it has to do that anyway for any compound sigiled name like $foo::bar, which is really foo::<$bar> 23:50
masak *nod* 23:51
TimToady since 'foo' is allowed to be a named lexical scope, seems like it oughta work
std: my $foo; UNIT::<$foo>; UNIT::<$bar> 23:52
p6eval std 30546: OUTPUT«===SORRY!===␤Variable UNIT::<$bar> is not predeclared at /tmp/2dWtcRlrKN line 1:␤------> my $foo; UNIT::<$foo>; UNIT::<$bar>⏏<EOL>␤Check failed␤FAILED 00:01 110m␤»
masak TimToady: did you see my confusion earlier about the lack of warnings from STD about redeclarations involving 'our'?
TimToady yes, and it's in my todo file 23:53
which keeps growing... :(
masak sorry about that. 23:54
sorear STD has bugs?
I thought STD only has LTAness
masak *gasp*
TimToady shh!
sorear wonders how many more bugs STD would have if it bundled a compiler 23:55
masak well, people are working on finding out :)
TimToady well, I know for a fact that [op] args doesn't actually store the args anywhere :)
sorear incidentally, I wonder how hard it would be to get roles working in NQP-rx 23:56
TimToady and I know that the tie-breaking rules for ambiguous LTM matches probably doesn't take inheritance into account correctly yet
sorear (you're allowed to use src/metamodel/)
TimToady and I'm sure if I actually look back at my todo file I could find quite a few more bugs :) 23:57
sorear if we had /that/, it would be fairly simple to have slangs in rakudo
just think about it! q:s! lexical macros! use COBOL! actually skip the last one

masak why, when I call `sub foo($p) { return { $p } }` twice, do I get two different closures? when is the cloning done? 23:59
