adu what does "Method 'match' not found for invocant of class 'String'" mean? 04:16
04:16 qelseio left
diakopter context? 04:16
adu I'm calling parse() on a grammar 04:17
diakopter do you have any inline code in the rules?
(I don't remember from when I read through your xml grammar)
adu this is a new grammar :) 04:18
sorear adu: It means you, or something you called, tried to invoke .match() on a raw Parrot String object
raw Parrot Strings don't have a .match method. hence, it failed.
adu i suppose I should paste
pastebin.com/xSpeq9r7 04:19
sorear Why is that error message confusing? How can it be improved? 04:20
adu first of all, I can't find any inline code
secondly, I never call a .match method explicitly, so I don't know what else to look for
sorear Did you see that it has a backtrace?
hmm. I am getting confrontational. I should drop this. 04:21
adu there is no backtrace
diakopter hugme: hug all
hugme hugs all
adu :)
sorear what, no backtrace? :|
adu indeed
diakopter decides to run it 04:22
adu I have a file with "say Go::Grammar.parse(@*ARGS[0]);" in it
and "use Go::Grammar;"
that's how I'm running it
diakopter what are you supplying to args 04:23
go go gadget grammar

diakopter ok. I give up. switching to linux rakudo
sorear: oops :) 04:29
sigh. even more fail. 04:31
I blame pastebin.
adu: well, your use of ** is incorrect 04:34
at statement_list
** is for (un)bounded repetition with a range 04:35
adu that might be it
diakopter use ]* % ';'
adu I commented out everything until it gave a different error
diakopter except I tried it, and even more fail
adu ws should be \s*
not \s
hehe :)
sorear diakopter: what adu has is the old syntax, rakudo ought to still support it 04:36
diakopter: also, x**y is x+ % y, not x* % y
adu thanks for helping :) 04:37
it works now
this will be my third Go parser 04:38
diakopter sorear: did you test that or are you just saying "rakudo ought to still support it" because... why?

sorear 'String' is a PMC type, not a Perl 6 type
it *has* to be Parrot leakage.

adu so both
right that was an error in my code as well 05:46
anyways, the grammar is working quite well now

not_gerd hello, #perl6 08:30
is it possible to compile .pm -> .pir from within a script (ie without spawning a new Rakudo process)? 08:31
brrt euh... 08:34
this is a moritz question
not_gerd ;) 08:35
brrt but, yeah, probably, if you can get access to the rakudo compiler object
which is what the compreg() opcode does for parrot 08:36
but, i'm not sure rakudo gives you access
not_gerd well, there's always pir::
not_gerd needs to figure out how pir::compreg__Ps('perl6') works 08:37
or rather, if it does what I want
brrt probably, yes
but i'm not sure if the registered compiler is rakudo or perl6
compreg returns either NULL or a HLLCompiler 08:38
not_gerd pir::compreg__Ps('perl6') return a Perl6::Compiler
^returns 08:39
08:39 drbean left
brrt oh, that will work 08:40
can you find the relevant documentation?
not_gerd brrt: probably
08:40 drbean joined
brrt great :-) 08:41
not_gerd just hope that they are up to date ;) 08:43
moritz you'll probably need to read the sources 08:55

moritz r: my $comp := pir::compreg__Ps('perl6')
p6eval rakudo 809b8f: ( no output )
moritz you must emulate the stuff that's in src/main.nqp
brrt no synopsis for getting the compiler yet? 08:58
moritz ie create an @*END_PHASERS dynamic var, then invoke $comp.command_line
not_gerd my current problem is that I can't use Perl6::Grammar (which I assume is NQP) from Perl6 08:59
I don't know how to get at hll-config as well, as it seems to be lexical 09:01

moritz wow, that seems to have invoked the REPL or something 09:06
strike
the first element in the array to command_line is supposed to be the executable name 09:07
brrt thats dangerous stuff, really 09:08
moritz not_gerd: gist.github.com/2894632
not_gerd: that's only a first shot, you still need to separate the lists for the END phasers and so on
not_gerd: but you don't need to 'use' Perl6::Grammar etc. separately, because main.nqp already does that 09:09
tadzik moritz: why's there both filename.pl and A.pm?
09:09 drbean left
moritz tadzik: because HLL::Compiler expects the executable name at index 0 09:09
not_gerd moritz: figured that out as well - it seems the compiler object that compreg returns is already set up 09:10
09:10 drbean joined
tadzik okay 09:10
moritz and with RAKUDO_MODULE_DEBUG=1 ./perl6 -I. -e 'use A;' I could verify that it actually loads A.pir 09:11
tadzik it that much faster compared to run("perl6 bla bla")? 09:12
I guess startup time isn't that painful nowadays
not_gerd tadzik: I'm still working on a dwimmy ufo version 09:14
I'm making it portable by not using shell built-ins but perl6 code 09:15
tadzik I see
not_gerd so compiling to pir means starting a perl6 process which immediately shells out to perl6
and that's... not that fast ;)
tadzik yeah. I guess Panda could use that too
and if it did, we could quickly test if it doesn't break anything 09:16
not_gerd now, I need a replacement for rm -rf
tadzik and if that is possible, then we could be pretty close to Pod module
not_gerd how do I get a list of files in a directory?
tadzik not_gerd: doesn't Shell::Command have it?

not_gerd for some reason, it has extremely slow startup

my exception grant is finished
my ufo rewrite is finished and waits for review 10:26
tadzik congratulations!
moritz the question is: what to hack on next?
I'll throw around some ideas
tadzik if I were you I'd take a look at P5 interop
moritz 1) focus on the book and other documentaiton effort (not too much fun)
2) more DBIish work (maybe add niecza compatible backends?) 10:27
JimmyZ thread!
phenny JimmyZ: 04 Jun 16:38Z <TimToady> tell JimmyZ irclog.perlgeek.de/perl6/2012-06-04#i_5680738 is right behavior, except that the compiler should really warn about "Useless use of 3 in a sink context"
moritz 3) precompilation stuff (though jnthn kinda seems a better fit for that; OTOH he seems a better fit for nearly all topics... :-) 10:28
4) start to partially port Mojo to p6
JimmyZ or Dancer? 10:29
moritz 5) trace module loading, so that compile time excpetions can show the module loading backtrace
p5 interop and threads aren't topics for me 10:30
mojo vs dancer: I happen to have used Mojolicious
JimmyZ doesn't know what's the difference between Mojo and Dancer 10:31
10:31 stepnem left
moritz and it has zero dependencies, so it's a much better target for porting 10:31
tadzik Dancer limits itself to what Mojolicious::Lite provides
JimmyZ Dancer has some dependencies?
tadzik yes
moritz JimmyZ: deps.cpantesters.org/?module=Dancer...;os=any+OS 10:32
tadzik small ones, I happen to live without them when working on Bailador (so far)
10:33 stepnem joined
moritz the other reason is that Mojo provides lots of basic web stuff that we need anyway at some point (cookies, HTTP classes, DOM tree handling etc.) 10:33
anyway, those were just some ideas 10:34
and I feel torn
not_gerd Stage parse: 1.610 10:35
moritz documentation would probably the most beneficial, but least fun, and rather frustrating
JimmyZ I'm +1 to 4 _ and 5 )
not_gerd another regression in parsing speed :(
JimmyZ 4 ) and 5 )
moritz not_gerd: is that after updating to newest rakudo? 10:37
not_gerd moritz: yes
moritz not_gerd: iirc jnthn said he had some ideas for optimizations 10:38
tadzik moritz: Mojo seems a worthwhile goal. I keep finding myself reimplementing lots of HTTP stuff for various projects, so having them collected, well-written and maintained will be awesome 10:39
moritz "Web depends on HTTP::Daemon, which was not found in the ecosystem"
eeks
tadzik it's been like this for ages :)
not_gerd is it possible to precompile scripts?
naive approach fails with Missing or wrong version of dependency 'src/Perl6/World.pm' 10:40
brrt1 thinks it is, perl6 --target=pir or something?

... or perhaps I should use grammars... yeah... that's the solution 10:43

ie 'string'.comb(/42/)
GlitchMr Works :) 10:52

colomon GlitchMr: note that comb by default returns strings, if you want Match objects from it you need to use the :match argument 10:56

[Coke] (smarter than perldoc -f: grok)
pmichaud than someone needing to edit the source code files to update the docs.
tadzik true
pmichaud as far as compile speed goes, we could certainly fix tools/build/gen-cat.pl to strip pod from the src/core/ files as it's building CORE.setting 13:16
tadzik why would we have it there then? 13:17
pmichaud well, there is something to be said for having the documentation near the thing being documented
and when pod-in-setting works, then we'd have .WHY working on the builtins 13:18

moritz I'm pretty sure it was never on a roadmap of mine
pmichaud at least, not in any sort of short-term or medium-term roadmap.
xinming I don't mean roadmap
I remember that when we are at pugs age, And people compiling perl 6 into javascript 15:27
and someone "said"(maybe I'm wrong), That we can write a C emmit kind of thing to generate C code directly.
pmichaud I think I remember hearing that, yes. I don't know how feasible that's ever been. 15:28
[Coke] the problem with that is eval. 15:29
s/the/a/
TimToady well, all you have to do is emit a parrot too, which is in C :)
pmichaud well, I suppose someone could write Perl 6 code that implements a Perl 6 VM (including dynamic stuff) and is translatable to C.
arnsholt I'm not sure I see (much) of a use-case for emitting to C 15:30
adu "all you have to do"
arnsholt But I do think in the really long term someone'll probably get around to writing a compiler that compiles to native code
PerlJam arnsholt: the usual reason is "speed" (but we know how that turns out)
pmichaud adu: TimToady often says "all you have to do" :-)
adu: "All you have to do is implement protoregexes and longest token matching via DFAs and ... " :-P 15:31
arnsholt PerlJam: There is that, but I think a compiler to machine code is more viable. Not unlike the state of Common Lisp compilers
Most of the CL compilers are written in CL and emit machine code (just like C compilers tend to be written in C) 15:32
xinming arnsholt: If I remember right, sbcl can compile lisp code to C 15:33
adu clj emits jvm
[Coke] I'm more sanguine about parrot getting a JIT in the next year than I am about rakudo or niecza emitting C. 15:34
adu I was interested in doing that
arnsholt Definitely. Native-code compiler is very-much a long term possibility, I think. Not just something that can be magically conjured into existence 15:35
moritz fwiw the codegen part (when compiling to C) will be much less work than providing all the runtime support
arnsholt Well, true. But it's not very useful without the runtime support = 15:39

pmichaud in perl6/doc, is it worth it to come up with a shorthand notation that indicates implementation status? E.g., "r+ n+"? 17:16
(borrowing from the 'features' repo for the moment.) 17:17
I'm also reminded of the IndexDotHTML support key system: www.blooberry.com/indexdot/misc/suppkey.htm where they indicated support for HTML features by browser type 17:19
(yes, it's very outdated; the idea is the thing)
moritz pmichaud: don't think it's worth the shortcut 17:21
pmichaud: there's enough implemented stuff we can document first :-)
pmichaud okay. I'm just wondering about "not implemented in XXX" becoming stale 17:22
having a shortcut means we might be able to use this to have a "detailed features" online matrix
but since I'm not doing the work (yet), it's just an idea and not really a "iwbni" :-)

GlitchMr How can I make Perl 5 style sub. That means I can use it either as method of class or by specifying it as first argument?
So I could do both of those:
$something->do_that('a')

and
Something.do_that($something, 'a')
moritz you can't do that in p5 either

moritz and in grammars you can write your own token ws that fits your needs 18:28

[\n <!semi>] 18:31
where <semi> matches newlines under certain conditions? 18:32
moritz well
that would be an \n not followed by a semi
maybe you rather want <!semi> \n ?
adu [\n & <!semi>]
moritz no
adu <!before semi> \n 18:33
moritz & is for matches of the same length left and right
adu <semi> either matches ';' or \n
moritz <!before <semi>> and <!semi> do the same thing
adu those are both the same length
moritz but <!semi> matches 0 chars

if you want it from the file you're in that should be quite easy 20:37
moritz from a different file
tadzik even easier if we implemented all the spec :)
now that's a hard part
moritz p6doc Str.split # searches for Str.pod =head3 split # or so
tadzik as we don't really have a Pod Parser which we can tell "parse this file"
moritz we do
it's called perl6 :-) 20:38
tadzik well, yeah :)
but you'll have to execute something from another file's UNIT scope, or so
moritz I've now done a regex job and extracted the pod section into a temp file
p6doc Str.split # works
it's not a nice solution, but better than nothing
tadzik true
moritz now we just need docs :-9 20:39
tadzik okay, you have all the pods in $=pod, which is an array of Pod::Blocks

tadzik accessing, from a perl 6 code 20:49
so far the best idea is "my $somepod = eval(slurp('foo.pl') ~ ';$=pod');", which is hardly awesome
moritz tadzik: I think the best approach is to install a hook between the pod parser and the emitter 20:52
and which can transform the pod tree 20:53
tadzik an emmiter is called from within the file with $=pod
moritz yes
but we already have hooks to use a different emitter

jnthn pmichaud: Even if redo/next/last are not used.
pmichaud I'm not sure what this is in reference to.
jnthn pmichaud: but it's expensive when you have while loops in your LTM code.
pmichaud oh!
jnthn pmichaud: I don't have a way to write a loop in NQP, so far as I can tell, that doesn't result in creating a Parrot ExceptionHandler 21:37
pmichaud: I don't think that's very cheap :)
pmichaud we could make one. 21:38
nqp::while(...) with some option that says "don't generate exception handlers" 21:39
jnthn pmichaud: Yeah, something like that.
dalek p: dceb34b | jnthn++ | src/QRegex/Cursor.nqp:
Simplify and improve performance of !alt a bit; creates less junk. ~4% improvement on CORE.setting parse time.
pmichaud in our other Actions.pm stuff, do we make much use of 'next' or 'last', ooc? 21:40
jnthn Not much.
dalek c: beac27d | moritz++ | lib/Pod/To/SectionFilter.pm:
add a Pod::To:: module that searches for a given section
jnthn Or at least, I don't remember off hand anywhere that we do.
pmichaud I count seven instances in src/Perl6
moritz 3 x last, 1x next
in Actions.pm 21:41
pmichaud er, 6 instances
3 in Pod.pm, one in ClassHOW, 2 in Actions.pm
('next')
so, it does get used some.
Hrm.
jnthn Seems a shame to penalize every while loop though.
Especially when we can probably statically detect it.
It's lexical, innit? 21:42
pmichaud according to p6 it's lexotic
jnthn Or at least, we can constrain NQP that way.
pmichaud which means dynamic
jnthn Ah.
pmichaud I wouldn't be opposed to making it lexical-only in nqp
dynamic instances of next/last aren't really all that common
or, more to the point, I wouldn't mind that someone would have to code a loop such that it can detect the need for the handler lexically 21:43
jnthn *nod*
pmichaud i.e., you only get the handler if there's a lexical next/last/redo. The handler is still dynamic; but you have to explicitly add a next to get it.
thus if 0 { next; } would be good enough to generate the handler but not cause much of a runtime cost 21:44
so, we'd need to extend the ast while node to have an option that says "don't install a handler", and then have the lexical detection of next/redo/last 21:45
jnthn Yeah 21:46
pmichaud I wonder if it makes sense to do the same for 'for' loops. :-) 21:47
(I believe they share some of the underlying code gen anyway.)
for that matter, I wonder how many of our occurrences of next/last actually occur in while loops :)
jnthn Oh, I thought aht's what you'd searched for 21:48
I didn't realize you were looking at for loops too :)
pmichaud no, I just searched for instances of next/last
lichtkind jnthn: model6 landed fully?

lichtkind hai 21:48
i mean that this work on wrenching model6 into rakudo is now completed? 21:49
pmichaud jnthn: ooc, which ltm code are you looking at wrt while loops?
jnthn !alt
And !protoregex
pmichaud is the cost of the handler showing up in a profile, ooc? 21:50
I mean, it's one handler per while loop, not one per while loop iteration 21:51
jnthn I'd need to do a C level profile...generally I just know that reducing the amount of junk each !alt call generated just made a fairly sizable difference. 21:52
And that ExceptionHandler creation there is probably multiple PMCs. 21:53
iirc, there's an RPA of the handler IDs created also
Or maybe it's just the one...
Plus the ops to set it up
Just looking for ways to streamline !alt and !protoregex, really.
pmichaud they're showing up in the profile?
(just checking for confirmation, not doubting that they could be) 21:54
jnthn I remember it showing up in the last C level profile I did...lemme generate a new one.
Problem is...the answer is fuzzy (more)
pmichaud I agree the exception handlers can be expensive -- we've seen that when we did rakudo-level subs
jnthn I don't have a way to correlate the "we spend time creating them" in the C level profile with the HLL level profile. 21:55
pmichaud does every method/sub/etc still get an exception handler to catch returns? I think you detect those lexically also, iirc
jnthn So in a sense even though I recall there being some cost there, it's ahrd to actually conclusively say "it's the while loops here"
In NQP? 21:56
pmichaud yeah, in nqp
jnthn It only gets a return handler if there's an explicit return.
pmichaud so yes, having while and for loops only get iteration handlers on explicit next/last/redo seems very doable.
jnthn It detects it's there, then adds it only if needed.
pmichaud at least seems like it could follow a similar pattern.
jnthn *nod*
lichtkind jnthn: i just wanted ask beause i read in your blog nowadays only about QAST and such and was wandering if 6model is an topic anymore 21:57
pmichaud and I suspect also that it means that many (most?) exception handler creations you're seeing are coming from loops, not methods or subs
jnthn pmichaud: Yes, that's my guess. I wish I had better data.
Not sure how to get it.
lichtkind: The core of 6model is largely stable enough these days that it doesn't see much development.
pmichaud I can certainly do a few tests to see how much the exception handler creation might be costing us. 21:58
jnthn lichtkind: The point of 6model was that we'd do development of meta-objects in a HLL (like NQP) though.
pmichaud: Could be good to get an idea of what it might save us.
lichtkind jnthn: thanks i slowly preparing for the next update article :)
pmichaud jnthn: actually, come to think of it, I already have a perfect test case. the MapIter code has to install an exception handler -- I can compare it to with/without pretty easily 21:59
just a sec
dalek p: d738608 | jnthn++ | src/QRegex/Cursor.nqp:
Similar simplification to !protoregex as just done to !alt; much less noticable difference, probably because we just pick the first answer much of the time and it works out.
pmichaud jnthn: have you tried replacing new "ResizableIntegerArray" with a clone yet? 22:00
istr you said that showed up on the profile some.
I also wonder if RIA is at all suboptimal. Doesn't seem likely, since we only really do push + pop on it. 22:01
jnthn pmichaud: Not tried that yet.
22:01 pupoque joined
jnthn pmichaud: fyi, !alt is called 323,000 times in CORE.setting parse. 22:02
pmichaud oh! 22:03
the other thing you could do is to replace the while loop with Q:PIR { ... } -- like MapIter does 22:04
jnthn Yeah, I was hoping not to do Q:PIR blocks :(
pmichaud I agree that's not a general solution to the problem, but for hotspots it's plausible
and when we get fast loops again we can always go back :)
okay, trying mapiter w and w/o handler 22:05

pmichaud 50K while loops with handler installed: 17.048 sec
22:11 Telgsta joined
pmichaud 50K while loops w/o handler installed: 16.263 sec 22:11
jnthn Oh?
That's...much smaller than I'd have imagined. Hm.

jnthn Pretty small difference. 22:12
pmichaud that particular test might be swamped by other execution time stuff; but it's clear that the time involved is on the order of 0.8 / 50000 sec 22:13
r: say 0.8 / 50000

jnthn Adds up when you do it 300,000 times...
pmichaud yeah, 300K loops would add 5 seconds
jnthn And the profile says we're doing that many. 22:15
pmichaud out of 100 seconds (on my box) needed to parse CORE.settings, that means it's costing 5%
seems worth fixing at some level then
plus, that's just the cost of the while loops for the alt handler
we have lots of other loops in the compilation :)
jnthn Yeah.
Well, we have one in !protoregex, but that one actually *uses* last. :) 22:16
pmichaud so, +1 to fixing it. Need me to adjust the PAST nodes, or ... ?
jnthn Depends how soon we want the fix.
pmichaud I'm thinking of all of the while and for loops in Actions.pm, though.
jnthn I mean, maybe we just do it right in QAST? :)
pmichaud well, doing it right in QAST goes without saying :)
I can certainly add a replacement 'while' node type to PAST that provides the new capability 22:17
or, since this is optional, I can even add it to Parrot's PAST nodes directly
jnthn If it won't take much time, it'd mean we can improve the parse performance in time for the next release. 22:18
er
It'd help us to improve the...
:)
pmichaud oh, the PAST part is pretty straightforward. I can do that, like, tonight.
the detection of lexical last/next is the trickier part, at least for me. But since you've already done it, I suspect you could do that quickly also :) 22:19
jnthn Hah, I just ahve a $*USES_RETURN or something in routine_def :)
pmichaud right, we just need a $*USES_NEXT or something 22:20
in statement:<while> and friends
jnthn Right.
pmichaud okay -- let's do this. if I get time tonight (likely), I'll work on the whole thing some.
I'll leave word via phenny about how far I get.
getting the PAST node updated should be no problem.
22:20 ponbiki joined
pmichaud I should have some time tomorrow, also, but my schedule has other events on it to deal with :-/ 22:21
plus I should probably make sure my stuff is ready for yapc :-)
jnthn Ah, yeah, YAPC is soon, right?
pmichaud I leave tuesday, it starts wed
jnthn k
pmichaud and a good bit of sunday is unavailable for me 22:22
jnthn OK.
I'm around quite a bit this weekend and early on next week
Towards next weekend I'll be largely afk
pmichaud anyway, I agree based on the above that avoiding the exception handlers is probably worth(pardon the pun)while 22:23
jnthn :P 22:24
pmichaud afk for a bit 22:27

spacebat_ trying to build rakudo on the nom branch, from a clean checkout, running Configure.pl has nqp complain it can't find libgmp.so.3, parrot complains it can't find libicuuc.so.42, then make-realclean fails with /usr/local/perl5/perlbrew/perls/perl-5.14.1/bin/perl5.14.1: not found 23:37
but nothing in my environment mentions perlbrew being under /usr/local, and nothing mentions 5.14.1, I use 5.14.2
I've build rakudo on this machine before alright, so I have libgmp and libicu installed 23:38
am I building a broken old branch? 23:39
23:39 drbean left
jnthn No, "nom" branch is the right one. 23:40
Latest commits were earlier today...I built latest recently also and it worked out. Seems it's something ICU related, though the perlbrew error is really odd too. 23:41
