jnthn mls: oh, nice...I'd got the original one queued up to apply today :) 11:17
mls I added the missing parts to mark_repr and free_repr
I also made the allocation of the gc_*_mark arrays more "on-demand", in the hope that some classes don't need them 11:18
jnthn +1 11:19
Looks good.
Yeah, any class the doesn't declare attributes won't need them. 11:20
Or any class taht only declares natively typed int/num attrs
mls Yes. It doesn't save much mem, but hey... 11:21
jnthn And making the str gc one lazy is a win for just about every class.
Well, every little helps :)
mls ok, I won't disturb your regex hacking anymore 11:22

moritz so the "allow nqp roles to be composed into Perl 6 classes" is to allow the QRegex stuff to be composed into Perl 6 grammars, with its own Match objects? 13:39
pmichaud yes
as well as other things we may eventually want/need 13:40
but essentially we'll have class Cursor does QRegex::Cursor { ... }
which defines a (nom) Cursor class that incorporates all of the attributes and methods needed by the regex engine
jnthn moritz: Also, much of the Perl 6 metamodel is defiend as NQP roles, so we'll want this for meta-programming 13:41
moritz jnthn: thought so
jnthn So I'd planned to sort the NQP roles in nom stuff at some point, pmichaud++ just gave it a priority bump :) 13:42
13:44 daniel-s joined
pmichaud the new regex engine won't really care about the structure/parentage of Match objects -- that'll be entirely up to the (HLL's) Cursor class to manage 13:45
moritz I kinda guess that also makes it easier to construct correct matches from rx:P5// 13:46
pmichaud yes
moritz (for example (foo)+ capturing only the last foo, not all of them) 13:47
pmichaud oh, that's one way to do it, yes.
More likely is that the P5 regex compiler says not to treat those captures as arrays 13:48
but yes, that's the sort of thing that becomes much easier
moritz (though I suspect that p5 regexes are rather low on everybody's priority list)

pmichaud the one that could be big is Merge branch 'qregex' into master

moritz did you push it?
pmichaud yes
moritz maybe you were in the wrong branch when you typed it
pmichaud well, the merge was really clean 13:51
all the files appear in nqp/master now, so I think it worked.

jnthn They show up in github.com/perl6/nqp/commits/master too
moritz weird, the commit "Merge branch 'master' into qregex" (69aa48218757ae5fc5d0a072ab982ea0466d36af) shows up in master... I would have expected it in branch qregex 13:52

moritz that has always felt a bit... arkane 13:57
pmichaud we can follow STD's model for handling that... now that STD has one :) 13:58
actually, it was always intended that we'd use dynamic vars for that... just never went back and updated the code to work that way.
there's even a comment in the original source to that effect. :)
github.com/perl6/nqp/blob/qregex/s...ions.pm#L3 13:59
moritz :-)
pmichaud but yes, it's far cleaner now. Lots of stuff is far cleaner. 14:00
moritz does nqp already bootstap itself with qregex?
pmichaud no.
I was going to do that... but ran into time distractions last night.
I then decided that bootstrapping before some level of nom integration wasn't optimal
moritz then I should stop distracting you :-) 14:01
pmichaud because any changes needed to qregex in order to get it to work in nom could complicate nqp building
14:01 daniel-s joined
pmichaud so, we'll get it far enough today to prove that the basic concepts are sound 14:01
and have qregex available in both mainline development branches (nqp/master, rakudo/nom)
14:02 _daniel-s__ left
pmichaud after we've proven that that works, I'll make a new branch to get nqp to build itself using qregex instead of the old engine 14:02
and when that works (and when that version of nqp can build nom), we'll be completely on the new engine
so, this ends up being a better plan, and jnthn and I can focus on the nom regex parts before his vacation and I can do the nqp bootstrap parts at a less-rushed pace 14:03
14:04 kaare__ joined
pmichaud and we may also have regexes in nom sooner, although I want to avoid doing much with regexes in CORE.setting just yet. 14:04
jnthn: so, here's where we stand.
(1) build nom
(this should bring in the updated nqp w/qregex stuff)
(2) try compiling the perl 6 "regex abc { abc }" to PIR 14:05
I'm getting a strange null PMC error when I do that... trying to track it down.

14:07 yath_ is now known as yath
jnthn looks forward to faster builds of everything once QRegex is used to build NQP... :) 14:08
pmichaud me too... hope it works out that way. (I'm certain it will.) I haven't been able to do any good timing benchmarks yet.
but, I'm also in "get it working" mode more than "make it fast", although I am taking out any pieces that are obvious slowdowns 14:09

14:10 daniel-s_ left
pmichaud especially when debugging. also it makes it a bit easier to find it later :-) 14:10
jnthn pmichaud: Are you wrapping the generated regex into any kind of Perl 6 code object just yet? 14:11
Doesn't seem that way ATM
pmichaud the object passed to buildsub
(no, I haven't done (m)any changes to make sure that the regex code is properly nommified
I figure you can help with that :)
jnthn oh 14:12
pmichaud ::buildsub accepts an already-created PAST::Block in which it can push the regex code.
jnthn yeah, regex_def is like, completely bogus :)
pmichaud I suspect it's left over from master? 14:13
jnthn right
I'd not touched it at all
So it needs a more serious update :)

pmichaud in fact, I think it's likely that its replacement will simply take a PAST::Node as an argument and push the regex code onto whatever Node you send it

pmichaud radcalc is wrong wrong wrong 15:15
we should not have a radcalc at all.
moritz well, we need something that turns a string into numbers
at a given base
pmichaud I agree. radcalc isn't it.
moritz (and I want to run it at compile time, just to be sure)
pmichaud it has to be runnable at compile time, but it also has to be usable at runtime. 15:16
moritz and I think it will be, though we need to stick a pretty API in front of it
pmichaud if you want to put in a radcalc for now, I'm okay with that... just know that I plan to rip it all out when I do an overall string-to-number fix. 15:17
moritz what I have now is a function that receives information like base = 10, string = '34_67.03'
jnthn > say (anon regex abc { def }).WHAT 15:18
Regex()
moritz and optional an exponent
jnthn \o/
pmichaud in general, basing any sort of string-to-number conversion on the way that master does things is wrong. master has a patchwork of string-to-number converters made by five different authors and all of them incorrect/incomplete in some way.
moritz and it automagically returns an Int, Rat or Num (or lower case if you want), depending on the string
IMHO that's about as correct as we can get it
pmichaud okay, I'll be glad to look at the one you submit, then.
and make comments and let you fix it :) 15:19

pmichaud jnthn: I can get rid of my usages of ++, no problem. 15:30
jnthn pmichaud: No hurry. I really thought I'd killed it.
pmichaud be aware that Actions.pm and BacktracePrinter are using it as well

pmichaud I guess that means that Cursor also needs to be meta'd properly.

pmichaud I don't think it's loaded in NQP yet.
jnthn No
I meant, in NQP code.
Loading it in Perl6::Grammar counts.
pmichaud oh, so I don't need the 'use ...' ?
jnthn It's ickier than that. 15:58
NQP and nom don't share enough module loading stuff yet.
pmichaud how does NQPP6Regex work then?
jnthn NQPP6Regex? 15:59
pmichaud shouldn't QRegex be basically the same? Or is it that we never access NQPP6Regex stuff from Perl 6 code?
jnthn We never access NQPP6Regex from Perl 6 code
pmichaud ah.
jnthn If you do a use statement in nom and a use statement in NQP and they both hit the same module we get issues at the moment.
There's an easy solution though.
pmichaud well, it's clear that QRegex / NQPCursorRole will be loaded for Actions and Grammar :-) 16:00
jnthn use QRegex; somewhere in BOOTSTRAP
(which is in NQP)
And then just export it to Perl 6 land from there.
as in, export NPCursorRole
*NQPCursorRole
pmichaud then do I remove the "use QRegex" from Perl6::Actions and Perl6::Grammar ? 16:01
or leave it there also?
jnthn Leave it there also
BOOTSTRAP is written in NQP
So we don't hit the issue
Actions, Grammar and Metamodel are all separate compilation units so they need to individually use QRegex 16:02
pmichaud wfm
jnthn NQP has Perl 6-y semantics on that these days, rather than Parrot global namespace semantic.
pmichaud yes, I know :)
I'm very happy about that.
jnthn tbh, Perl 6's ModuleLoader is kinda still at the "jnthn needed the simplest thing that'd possibly work and so wrote it" stage. 16:03

pmichaud in ffa93fc (just pushed) I have Cursor with a method declaration commented out.

No, it's not an override.
even something as simple as
my Cursor does NQPCursorRole { method xyz() { say 'xyz' } }

jlaire 'my class Cursor'...
vs 'my Cursor'...
jnthn sorear: Pulling in HOWs is the first thing CORE.setting does
pmichaud gist.github.com/1081042 # example of it running outside of the setting 19:02
jnthn Yeah. The fun of stuff with the setting is that you can easily end up depending on code in the setting.
pmichaud I think even a null method declaration triggers it, though. (checking) 19:03
[Coke] jnthn: do you need ... layers of setting?
jnthn pmichaud: No, it's the role composer that's trying to strinfigy something.
pmichaud: And that stringification is giving us the infinite recursion. 19:04
dalek kudo/nom: c0e38e1 | pmichaud++ | src/core/Cursor.pm:
Remove debugging says from Cursor.BUILDMATCH.
 19:05
sorear jnthn: I was referring to the typo in pmichaud's paste 19:06
pmichaud (wasn't really a paste, I typed it out by hand, which is why it was missing the 'class')
jnthn pmichaud: Hmm. Oddness...we don't actually have much after Cursor in the setting. 19:07
PerlJam When does MATCHBUILD execute exactly? 19:08
pmichaud jnthn: correct, it's towards the end on purpose.
PerlJam: whenever a cursor object needs to build a MATCH. It's a callback.
19:10 birdwindupbird joined
pmichaud on a slightly different topic... in Actions.pm, how much code will /abc/ have in common with regex { abc } ? 19:11
Should we factor out the regex construction somewhere?
similar things for s///, m//, etc.
jnthn pmichaud: There's probably more factoring out to do there, yeah. 19:12
pmichaud I can try a refactor... any obvious differences that need to be there? 19:13
jnthn pmichaud: What do you expect /abc/ to produce?
pmichaud the same as regex { abc }, mainly. 19:14
there are some minor differences, but the core of the regex generation ought to be the same
19:15 masak joined
masak oh hai, #perl6 19:15
tadzik oh hai masak
pmichaud masak: o/
PerlJam masak: greets
masak what, in your view, is the (syntactically) nicest way to do an inverse array lookup in Perl 6?
tadzik nom did get some significant regex/parsing improvements recently, didn't it? 19:16
dalek kudo/nom: 8fc705e | jonathan++ | src/Perl6/Metamodel/RoleToClassApplier.pm:
A little tweak to the role applier to avoid triggering an infinite recursion that pmichaud++ ran into (there's some deeper issue to hunt here, but this should unblock things).
pmichaud tadzik: we're still working on them even as we speak.
jnthn pmichaud: Try that.
PerlJam masak: you mean given a value, find the index of the array element that has that value?
tadzik syntactically I'd go for .reverse
masak yes.
jnthn masak: preved
tadzik oh, I see
jnthn masak: One answer or all answers?
masak I have two value domains and I need to translate back and forth between them a bit. one of the domains is non-negative integers, so I'm using an array instead of a hash.
jnthn: all, please :)
jnthn: oh, you mean the mapping? :P 19:17
jnthn: it is assumed that it's bijective.
jnthn @array.kv.first(*.value == $wanted).key # works but looks a bit clumsy 19:18
masak I did something similar, doing .kv.invert on the whole array. 19:19
also a bit clumsy.
jnthn Feels like there must be a better way :)
masak aye.
hence my question :)
pmichaud @array.pairs.grep($value).keys 19:20
well, that's close
masak nice.
pmichaud not quite right
@array.pairs.grep($value)>>.key 19:21
masak or .key, I guess, if I know there's one.
pmichaud .keys would just give numbers to the pairs
needs to be >>.key
masak rakudo: my @a = <a b c>; say @a.pairs.grep("b").key 19:22
p6eval rakudo b4486e: OUTPUT«Method 'key' not found for invocant of class 'List'␤ in main program body at line 22:/tmp/TlrahQ6fX7␤»
masak rakudo: my @a = <a b c>; say @a.pairs.grep("b").keys[0]
p6eval rakudo b4486e: OUTPUT«Any()␤»
masak huh.
jnthn rakudo: my @a = <a b c>; say @a.pairs.grep("b").perl
p6eval rakudo b4486e: OUTPUT«()␤»
pmichaud oh
masak .grep on Pairs...
pmichaud yeah
hrm
masak not on Str
pmichaud gist.github.com/1081122 # \o/ 19:25
now it's just syntax. :-)
takadonet !! 19:26
masak pmichaud++
pmichaud jnthn++, too
tadzik nice :)
jnthn nom: my @a = 1,8,9,2,1; 1 until @a[++(my $i)] == 9; say $i 19:27
p6eval nom: OUTPUT«2␤»
jnthn Nil points for style! ;)
pmichaud: yay :)
dalek kudo/nom: 2a681a4 | pmichaud++ | src/core/Cursor.pm:
Add Cursor.MATCHBUILD, which builds the match object.
jnthn On the up side, it's got built in error detection: if your bijection isn't actually one, your program hangs. :) 19:28
pmichaud "hanging" is "detection"? ;-)
dalek kudo/nom: 6e1fa32 | pmichaud++ | src/core/Grammar.pm:
Uncomment Grammar type.
jnthn You'll detect something's wrong. ;) 19:29
jnthn guesses he wins "worst solution" for this one :)
pmichaud nah. solve the halting problem and it's a done deal :)
masak pmichaud: if "hanging" is "detection", solving the halting problem *is* a done deal :P
jnthn rakudo: (3,2,1,9,8).index(3).say 19:33
p6eval rakudo b4486e: OUTPUT«0␤»
jnthn ;-)
masak jnthn: you're breaking the wrong record! :P
jnthn :)
We could always overload .index on...no, we couldn't. :) 19:34
jnthn can see that a built-in along those lines oculd be useful though
masak I ended up with a sub inverse_index that wraps away pairs/first/key 19:35
jnthn Especially as there's a matching operation for hashes.
.how_would_i_lookup($x)
masak it's sort of like .first, but it gives you the index instead.
at least for arrays :)
pmichaud .indexof 19:36
jnthn: is the order of steps important in regex_def ? 19:37
i.e., could I move 19:38
jnthn pmichaud: Well, yes and no :)
pmichaud well, hrm.
jnthn pmichaud: Depends exactly what you want to shuffle around.
pmichaud I think I want to move "Do the various tasks..." down to just before "Install in needed scopes" 19:39
i.e., do all of the stuff manipulating $past first, then do the stuff that builds $code
19:40 thou left
jnthn pmichaud: This bit: 19:40
# Install PAST block so that it gets capture_lex'd correctly.
my $outer := $*ST.cur_lexpad();
$outer[0].push($past);
Can move earlier.
pmichaud: The self thing is delicate.
pmichaud yeah.
jnthn pmichaud: It gets pushed onto the end of [0]
It *must* go after bind_signature is called
Which is why it comes after the sig setup. 19:41
I tried to unshift it on to [1] first and it magically vanished. I never worked out why...
tadzik jnthn: my parrot_config says debugging => '1', do I need anything more for the segfault investigation?
pmichaud the problem with factoring this out at the moment is
my $closure := block_closure(reference_to_code_object($code, $past));
if I didn't need the reference to $past, then I could just return $code 19:42
or can I just put the "reference_to_code_object" inside of the setup block as well, and return it? 19:43
jnthn pmichaud: You could return reference_to_code_object($code, $past) and just let the other thing block_closrue it if needed
pmichaud yeah
jnthn Note
$code is *really* the code object
It's not a PAST tree.
pmichaud right
jnthn s/tree/node/
pmichaud so, a sub "make_regex" that takes a QAST tree and returns a closure 19:45
(and does the other setup/install)
seems workable.
pmichaud tries it.
oh, what about applying traits?
that requires the code object
[Coke] Is there a list of "most wanted modules for perl 6"? 19:46
pmichaud [Coke]: I think that list is commonly called "CPAN" :-)
moritz yes, linked to from modules.perl6.org
[Coke] yaya. just wondering about prioritization.
DOH. I was already on that page, but was skimming through the actual list.
moritz++ 19:47
partcl: puts Coke--
p6eval partcl 3977a9: OUTPUT«Coke--␤»
jnthn pmichaud: You'll only have them for regex_def
pmichaud so, two sets of regex closuring code?
hmmm
jnthn pmichaud: Note that the code object is attached to the PAST node reference_to_code_object returns.
sorear masak: is your array constant?
masak sorear: yes. 19:48
sorear o/ masak
masak \o sorear
jnthn pmichaud: You can do $ref<code_object>
pmichaud so I could just return reference_to_code_object and grab the code object from it?
okay, that works perfectly.
jnthn Right
And pass that along to the traits.
pmichaud so, regex_code_ref
sorear niecza: enum Foo (a => 1, b => 2, c => 4); say Foo("b"); say Foo(4)
Su-Shee [Coke]: SSL, Hashsums of all kinds, full blown LWP (JavaScript integration preferred), Net::*, The::Boring::Stuff::Like::Excel ...
p6eval niecza v7-30-gaf607ad: OUTPUT«Foo::b␤Foo::c␤»
sorear niecza: enum Foo (a => 1, b => 2, c => 4); say +Foo("b"); say Foo(4).key 19:49
p6eval niecza v7-30-gaf607ad: OUTPUT«2␤c␤»
Su-Shee [Coke]: Date, Time...
jnthn pmichaud: wtf
pmichaud: gah!
I meant
pmichaud: wfm
:)
tadzik :)
Su-Shee: we have Date and Time, afaic
jnthn I think "wtf" got too wired into my fingers at $dayjob earlier this week :)
sorear masak: if you have a constant array indexed by integers, I think Enum fits the bill perfectly.
[Coke] Su-Shee: add to: github.com/perl6/ecosystem/wiki/Mo...write-port 19:50
masak sorear: I agree completely.
Su-Shee ah it's editable..
masak sorear: which means I'll probably rerwite this part of the game when enums land in Rakudo.
[Coke] there is no sixperl call anymore, yes?
jnthn masak: I started enums in nom earlier today
masak jnthn: yes, I saw.
jnthn masak: I doubt I'll get all the way before I leave but it should be quite hackable. 19:51
masak jnthn: oki, good to know.
jnthn: just going to finish my current obsession :)
jnthn For your copious free time :P
masak :)
pmichaud jnthn: the line 19:55
$<longname> && $*ST.is_lexical('$?CLASS') ?? '$?CLASS' !! 'Mu']);
refers to a non-existent $<longname>. What should it be instead?
jnthn eek
in regex_def, probably deflongname
The grammar is wonderfully inconsistent.
method_def parses a longname and a multisig
regex_def parses a deflongname and a signature
masak :( 19:56
jnthn I thought it was just us then I checked std.
pmichaud I'm passing the name as a param so it's not a big deal :)
jnthn Not that we have to really follow STD when it doesn't suit us.
Maybe there's a good reason, I dunno. :)
masak then again, maybe not. 19:57
jnthn Yeah, could easily be not
Mostly I'd liek to just kill multisig anyway... :)
pmichaud is $inv_type setting the invocant t ype? 19:58
*invocant type?
jnthn pmichaud: Yeah
masak jnthn: yes, me too.
jnthn pmichaud: I wasn't totally sure what it should be for regex_def.
pmichaud well, if we're inside of a grammar or class, it should be the current class.
benabik Hm. Parrot master, NQP master: `P6opaque.c:858: error: cannot convert ‘P6opaqueInstance*’ to ‘PMC*’ in initialization` Any ideas?
jnthn pmichaud: If we're in a grammar, then clearly it's the type of the grammar.
masak jnthn: multisigs introduce more complexity than they give benefit back.
pmichaud jnthn: but what about
grammar { 19:59
masak benabik: doing what?
pmichaud method xyz() {
benabik masak: Compiling. Sorry.
pmichaud my $x = my regex { ... };
clearly that regex isn't tied to the grammar.
masak benabik: just wondering. I don't have a solution, sorry to say.
benabik: might be bootstrapping issues, if you've changed something.
jnthn pmichaud: Right, thus the $<longname> check. 20:00
benabik masak: This is plain Parrot master and NQP master.
masak benabik: disconcerting.
pmichaud okay.
wfm.
benabik Hm. I wonder if this is related to me using g++ instead of gcc for compilation.
jnthn pmichaud: and my regex foo { abc } actually gets installed in the methods table and the lexpad, so far as I follow the spec.
sorear [Coke]: AFAIK they still happen, but chromatic-- has stopped bothering to take notes
pmichaud we haven't had a sixperl call in quite a while. 20:01
I think we abandoned them in favor of #phasers meetings.
sorear *nod*
pmichaud I think the last sixperl call was in January.
jnthn benabik: That's a disconcerting error. 20:02
sorear jnthn: ISTR that we decided at some point that 'my regex' should NOT install in the methods table
jnthn benabik: I applied a patch to that file earlier today, wonder if it was something in that...
sorear unlike 'my method'
jnthn sorear: er
sorear I can't remember when or who though
jnthn That sounds horribly inconsistent
benabik jnthn: It was building a couple days ago. I suspect this is related to me switching parrot to use g++, which is notably pickier about these things.
jnthn Givne a regex is really just a kind of method.
Su-Shee I'm done, I added what I had in my head, DBI excluded
sorear I said the same thing, yes
[Coke] chromatic++ # undo slander. 20:03
jnthn sorear: I'm going to go with it installing in the method table if there's one to hand, but not whining if there isn't.
[Coke] karma g?
aloha g? has karma of 0.
[Coke] karma g
aloha g has karma of 512.
jnthn sorear: Which is what methods do too.
sorear: And hope that consistency wins a victory. :)
benabik [Coke]: g is just that awesome a letter.
moritz karma C 20:04
aloha C has karma of 533.
moritz C > g :-)
masak [Coke]: undo slander?
pmichaud alas, look slike Google+ should've been Google++ if they wanted to win karma points.
Or perhaps that should've just been Google+1
masak Google FTW
Su-Shee tadzik, [Coke] I'm done. 20:05
[Coke] masak: there's a negative karmic event a few lines back.
20:06 SHODAN left
masak [Coke]: ah, I see it. 20:06
sorear last notes from chromatic: 30 June 2010 20:07
benabik jnthn: Looks like it's g++ being very picky about type conversions. In #parrot, we sometimes use `--cc=g++ --link=g++` in order to cut down on tricky type errors.
jnthn benabik: Generally, when I write C I'm writing *C* and I leave C++ fixups to those who'd prefer it to be C++. :) 20:08
benabik jnthn: g++ compiles C just fine. It's just far pickier about pointer types, which can be very useful.
huf how does it know to dtrt when the two languages arent compatible? 20:09
sorear if there was a sixperl call in January, then I stand by chromatic--
pmichaud just because there was a sixperl call doesn't mean chromatic++ was present. 20:10
I suspect he was not.
benabik huf: C++ is mostly a superset of C. It tends to warn or error when you have C code that does interesting things with pointer type conversions.
sorear jnthn: parrot is designed to use the common subset of c89 and c++90, and will accept either kind of compiler
huf benabik: yeah, mostly 20:11
sorear: ah, tricky ;)
jnthn P6opauqe certainly does fun with pointers.
[Coke] if those calls ever start up again, it would be nice to have more perl6 people on them. ;) 20:12
jnthn Anyway, patches happily applied.
20:14 ab5tract left
masak is it just me, or have the GC runs in Rakudo actually gotten worse? 20:14
pmichaud in master or nom? 20:15
masak master.
the output from my adventure game contains noticeable pauses.
pmichaud don't know. could be.
what compiler are you using?
PerlJam masak: it's just your code ;)
masak PerlJam: :P
sorear ok 2262686 - $_ does not get set implicitly if a pointy is given 20:16
masak pmichaud: you mean besides Rakudo?
sorear was trying to run all test files against niecza to see which ones were promising
benabik For future reference that error means "User built parrot with g++", just so people know. :-)
jnthn sorear: That's a heck of a big test file!
pmichaud masak: I mean which version of Rakudo. Rakudo Star 2011.04, or Rakudo 2011.06, or ... ? 20:18
or by master do you mean "master HEAD" ? 20:19
masak oh.
This is Rakudo Perl 6, version 2011.05-21-g7175e54 built on parrot 3.5.0 RELEASE_3_5_0-13-g19bbdee
pmichaud that's an odd beastie. :-) 20:20
for 2011.06 on 3.5.0 I didn't notice any major slowdowns related to gc
I didn't run any tests on 3.5.0-13, but could potentially do that.
PerlJam masak: are you running on a resource constrained machine?
pmichaud probably a good idea before the weekend.
masak PerlJam: in a sense, yes. VM with not too much memory and a bit of a slowdown.
on a fairly new laptop. 20:21
pmichaud jnthn: gist.github.com/1081228 # really close now... how do I avoid the warning?
benabik Building Rakudo master, Parrot master, CORE.setting: Unrecognized nqp:: opcode 'nqp::hash' at line 3969, near ";\n "
20:22 birdwindupbird left
PerlJam Maybe there's some pathological GC behavior that that version of Rakudo still diddles. 20:22
jnthn pmichaud: Oh, hm
pmichaud benabik: that doesn't make any sense... Rakudo master doesn't have a CORE.setting
nor does it use nqp:: opcodes
jnthn pmichaud: I dunno how you've refactored it.
pmichaud did you mean Rakudo nom?
jnthn: I can commit... one moment.
benabik pmichaud: D'oh. Yes. NQP master, Rakudo nom. 20:23
jnthn pmichaud: I suspect that it's assuming ti's installing a method and looking for a $*SCOPE
And /.../ doesn't imply one.
pmichaud I think I can pass a scope to install_method
jnthn oh
Then pass anon
Which is correct really :) 20:24
pmichaud right.
benabik Oh, wait... I appear to have been running multiple compiles in parallel for some reason. I doubt this was a good idea.

also dont have Match.Bool yet
still a lot of pieces to put back into place
benabik One _awesome_ step. ;-) Just forgot that Rakudo didn't do the .list automatically.
pmichaud jnthn: so, looks like we have regexes in nom now. The rest of the stuff to be done for basic regex support is just adding in methods and cleaning up small pieces. 20:58

pmichaud having 'grammar' work will be great.
jnthn++ # awesome work on roles 21:06
I'm major impressed that we can compose NQP roles into Rakudo classes.
masak interesting point that ++ might be a macro. I think I like that, actually.
jnthn > grammar LolGram { }; say LolGram.^mro

21:07 bluescreen10 left
jnthn masak: You don't need it in real Perl 6 21:07
masak: Because real Perl 6 has assignment.
masak: The point is we can't have normal ++ in NQP because it has - and very probably never will have - assignment.
masak rightright. 21:08
pmichaud well, even in nqp-rx the postfix++ needed to be macro-ized somewhat, to provide the 'return value before increment' semantic.
okay, I need a short break and then I'll clean up match objects a bit more 21:09
jnthn :)

pmichaud I strongly caution against putting any regex-reliant code into the core setting or Test.pm.
masak lol
er. belay that :)
pmichaud There may still be some breakages imminent, and I'll suppress/remove any troublesome regex code if it's in my way and I don't have time to fix it :) 21:13
so, at least give me a couple of days to finish fleshing this out. The new engine is less than 4 days old, after all. :) 21:15
(at least in terms of code)

flussence I think I've figured this out... strace tells me nom is looking for modules in {.,blib,$build_dir,$build_dir/lib}/*.{pbc,pir,pasm} ... when I run it from another dir, that's not going to find $build_dir/blib/Perl6/Grammar.pbc or *any* .pm file 21:25
tadzik flussence: wklej.org/id/561565/ that's something I was doing a while ago trying to fix 'make install' in nom, YMMV, I don't know how it will work now 21:26
flussence that still leaves the problem that it's not loading .pm files at all... I tried running the Text-Tabs-Wrap tests and it barfed on all of them 21:29
jnthn flussence: nom can only load pre-compiled at the moment.
flussence oh, k

dukeleto++ # new README looks nice
dukeleto tadzik: "perl6 binary be in your path" and "perl6 binary is in your path" mean the same thing to me, but I can modify it if that is confusing 21:56
tadzik dukeleto: "that the perl6 binary be in your path" looks wrongish to me
maybe "requires the perl6 binary to be in your path"? 21:57
I don't mind if it's legal english, I may be wrong :)

tadzik :( "that the perl6 binary to be in your path" still sounds wrong to me. Don't bother if it's correct though :) 21:59
masak "that the perl6 binary be in your path". 22:00
tadzik s/be/is/ maybe?
dukeleto tadzik: yeah, you are right. I mixed up my edits. 22:01
pmichaud your path contains the perl6 binary
masak well, the "be" is there because of "requires", which makes it a subjunctive. but people don't care much for the subjunctive nowadays, so it could as well be "is".
dukeleto masak: lulz. that is what I said originally 22:02
masak oh, sorry, I'm not reading the backlog too attentively :) 22:03
pmichaud me either :)

tadzik dukeleto: do you have it installed? 22:10
dukeleto tadzik: i didn't realize that I have to install a different thing to run the panda test suite 22:12
tadzik: i just ran the test suite successfully with prove -e perl6 -rv t/
tadzik that's nice
22:16 Chillance left
dukeleto tadzik: i have seen the light: panda install ufo && ufo && make install 22:21
tadzik dukeleto: whywouldyoudothat? 22:22
if you already have panda installed, why would you install ufo to install panda? :) 22:23
dukeleto tadzik: just trying to give alternate ways of running the test suite in the docs
22:23 betterworld joined
dukeleto tadzik: should we tell people to just use prove ? 22:23
tadzik dukeleto: I think so, it's the least effort 22:24
if you want to just run the tests
22:25 wamba left
tadzik dukeleto: but, will -lrv be sufficient, does it load ext/? 22:25
test suite uses Test::Mock for example, so it's shipped in ext/. bootstrap.sh adds ext/ to PERL6LIB temporarily to install and test panda
dukeleto tadzik: i've noticed the -l does nothing for running perl6 modules, since it modifies PERL5LIB, and no, it doesn't load ext/, i don't think 22:26
tadzik so it's probably PERL6LIB=ext:lib prove ...
dukeleto tadzik: well, the test suite passed for me without that
tadzik dukeleto: you probably have the modules already installed 22:27
remove your ~/.perl6 and try
