adu I have a question, what is the purpose of "outerctx"? 00:27
github.com/perl6/nqp/blob/master/s...r.nqp#L219
00:28 pmurias left
jnthn Part of the mechanism for attaching the outer lexical context (the setting for scripts/modules, and the appropriate lexical scope for EVAL) 00:28
Actions.pm has the more interesting bits 00:29
adu jnthn: I'm trying to write a parser for NQP in something other than NQP 00:38
I'm finding it rather difficult 00:39
00:45 erkan left
ugexe m: class X { multi MAIN("test") is export {"test"}; multi MAIN("test",@more) is export {"test2"}; }; import X; say "hello"; MAIN("test"); say "world"; 00:45
camelia rakudo-moar 795a32: OUTPUT«hello␤world␤Usage:␤ /tmp/akr1TtchJu test ␤ /tmp/akr1TtchJu test <more> ␤»
ugexe why does the Usage message get printed at the end instead of calling &MAIN or printing the Usage before "hello" "world"?
i understand &MAIN_HELPER is called at the precomp stage, but im not exactly sure what i should extrapolate from that 00:47
00:47 erkan joined 00:48 bjz left
jnthn ugexe: A MAIN it called automatically, at the end of the mainline. So the mainline runs, then it calls MAIN, and since there are no command line args passed for the evalbot then you get the usage printed. 00:48
00:48 bjz joined
jnthn ugexe: Your own call to it likely worked out fine, but the idea is that MAIN is called automatically with @*ARGS, not that you call it yourself. 00:48
adu: I'm not entirely surprised. :) Though NQP is a good bit more tractable than full-blown Perl 6. 00:50
adu: There's a reason the two times I ported NQP, I ported the code-gen and then got it to cross-compile itself, so I didn't have to port the grammar and so on. :)
adu lol 00:51
jnthn: also, perl6-j is quite speedy, good job! 00:59
psch it is..? 01:00
i guess i'm not running enough long-running programs with it
adu psch: yes, it executes my C11 parser in less than 10 seconds, perl6-p executes the same program in under 5 minutes...
psch adu: did you try it on moar yet? 01:01
adu psch: yeah, perl6-m runs it in about 5 seconds
maybe I should do some more testing and put some benchmarks on my blog or something 01:02
01:02 erkan left
adu jnthn: have you heard of Graal/Truffle? 01:03
psch 5 sec moar vs 10 sec jvm sounds suspiciously consistent with my own experience
as in, stage parse while building rakudo also has 100% longer runtime on jvm than moar for me 01:04
looking at benchmarks is probably more reasonable though
adu psch: it's still much nicer than 1000x longer
psch adu: right, i'm not saying it's slow. i might just be a bit miffed with building on jvm for the interop stuff i'm working on :) 01:05
01:05 erkan joined, erkan left, erkan joined
adu psch: what are you working on? 01:05
psch adu: i'm working on mmd for overloaded constructs when instantiating java classes in perl6 01:06
currently we have to call them with a non-jvm-spec compliant method descriptor, e.g. "constructor/new/(I)V" for a constructor that takes an int
adu mmd? 01:07
multimonitor display?
psch but we of course would like to be able to call &.new
multi-method dispatch
adu oh
psch i've described mmd for methods in the day 12 of perl6advent 01:08
adu I thought JVM added invokedynamic in 1.7 for that
psch well, yes
we're also already using invokedynamic for a few things
but nobody had implemented it yet for interop
or rather, it wasn't user friendly 01:09
01:10 stapler joined, stapler left, stapler joined
adu psch: have you heard of Graal/Truffle? 01:11
jnthn adu: Yeah, I read a paper on Graal/Truffle a few weeks back. Interesting work.
adu every word reminded me of HLL::Grammar and NQP, and Parrot, ...
also: www.slideshare.net/ThomasWuerthinge...ethdec2013 01:12
provides a nice overview 01:13
01:19 stapler left 01:20 adu left 01:25 mvuets left, erkan left 01:28 erkan joined, erkan left, erkan joined 01:35 RSX-11M joined
RSX-11M is it possible "file".IO.lines but with "\n" preserved ? 01:36
jnthn Maybe open("file", :!chomp).lines 01:39
psch m: my @lines-with-break = slurp.comb: /<-[\x0a]>+.<after "\n">/; say @lines-with-break[0] # this'd work 01:42

psch note two ␤ at the end
although opening it correctly is probably cleaner
jnthn psch: That's...probably also not going to be so fast ;)
psch jnthn: right, it's probably not. i'm thoroughly in "make it work"-mode :) 01:43

psch probably not, i'm thinking the lookaround is the slowest bit

FROGGS__ moritz: pong
moritz FROGGS__: we talked about moving testers.perl6.org to the new server 12:50
FROGGS__ moritz: true 12:51
I'd need an account... somewhere I suppose :o)
moritz FROGGS__: the main question is: should it go on the www or the 'hack' server?
12:51 rurban left
moritz FROGGS__: how much CPU, RAM and disk space does it use? 12:52
12:52 rurban joined
FROGGS__ good question 12:52
lemme check
timotimo moritz: does the "security-relevant services" host have a name yet? 12:53
moritz www has 4GB RAM, and a single CPU; I could add another one with a short downtime
timotimo: no, it doesn't exist yet; I'm thinking maybe 'risk.p6c.org'
FROGGS__ moritz: is there a connection between both?
timotimo mhm 12:54
moritz FROGGS__: sure, both are on the internet :-)
FROGGS__ like, that the hack server could generate static html pages, and the www server would deliver these (using apache), and the www would also receive reports
so they'd need to share a prostgres db and a directory
maybe rsync'd 12:55
12:55 rindolf left
moritz FROGGS__: rsync should be pretty fast; I'd like to avoid setting up an NFS share 12:55
(they are on the same physical machine, so network between them should be pretty fast)
FROGGS__ yes, it feels like the right design anyway
jnthn FROGGS__++ moritz++ 12:56
moritz FROGGS__: mail or msg me your ssh pubkey, then I'll create an account for you on both servers
timotimo is www meant to do mostly static web hosting? 12:58
or are the web services supposed to culminate in a single web server via proxying?
moritz timotimo: it's dimensioned to also run some dynamic pages
timotimo: it has enough RAM to compile rakudo-m, so that's possible too
timotimo for some reason a single CPU still feels a bit weak; or is that two logical cores? 12:59
moritz timotimo: though highly CPU-intensive loads don't fit there
timotimo hm, i suppose web stuff is rather I/O bound
moritz timotimo: well, the server on which I run irclog.perlgeek.de (also written in perl) and a few mostly-static web pages is also a single core, and i mostly idles 13:00
timotimo i wonder how we'd get a libuv-backed socket on moarvm to do TCP fast open
moritz: ah, right. it's most probably mostly peak loads
gotta go AFK for a bit

Ulti ^ is my confusion 13:43
why the need for the first $_
timotimo so that it doesn't get parsed as a hash literal 13:45
$_ says "this is code block, yo"
Ulti I thought you would need the , for that
timotimo i don't think so
Ulti as in for it to be a hash rather than just a pair literal
timotimo m: say {foo => "bar"}.WHAT
camelia rakudo-moar 795a32: OUTPUT«(Hash)␤»
timotimo m: say {foo => "bar"}.perl
camelia rakudo-moar 795a32: OUTPUT«{"foo" => "bar"}␤»
jnthn I think the implicit use of $_ there should count
So I'd have taht as a bug.
timotimo hm, okay 13:46
jnthn I think there's an RT
Ulti I think its the {} looking hashy before they look blocky
that makes the => a hash rather than a pair
I mean this is what the * is kind of for 13:47
but I can't use it :'(

ssqq why in perl6, 1.1+2.2 == 3.3, but in NQP, 1.1+2.2 > 3.3, they have same backends, only with different grammar and action. 14:34
jnthn ssqq: Because 1.1 is not a floating point number in Perl 6
brrt 1.1 in perl6 is (iirc) a rational 14:35
jnthn And in NQP we cheat and make it one.
moritz ssqq: the difference is that 1.1 in Perl 6 is a Rat, which can store the 1.1 exactly
ssqq: but it's not a VM-level type, so NQP doesn't have it
jnthn We could just forbid 1.1 in NQP and force writing 1.1e0 if we want to really force Perl 6 compatibility
But I've barely cared; floating point isn't very useful in compilers, generally.
moritz (and it's not needed much for writing compilers)
timotimo aye
jnthn Sometimes I wonder if NQP could get away with assuming all math is integers and you have to write the nqp::add_n if you want the floating point. 14:36
brrt as in, completely untested by any part of the compilation stack
jnthn We'd generate better code that way. :)
brrt jnthn - i think you could and it would simplify stuff
jnthn It's tempting. :)
brrt very
jnthn After all, the point of NQP is to build compilers and other related runtime bits, not to be general purpose like full Perl 6. :) 14:37
ssqq jnthn: yes, I think float is useless to hack compilers.
14:45 brrt left
masak I'm surprised floats were put into NQP in the first place :) 14:45
14:46 atroxaper joined
moritz having floats is kinda useful for math that generates floats :-) 14:47
masak I guess...
moritz but I think it was really just parrot/PIR legacy 14:48
masak ...but even that explanation feels non-obvious to me. mixing levels, kind of.
moritz well, before NQP, rakudo was written in PIR (shudder) 14:49
so it's kinda obvious to have NQP provide all the PIR features that easily map into a HLL

masak ooh, I got a case where adding Grammar::Tracer changes the outcome of a parse :> 15:27
jnthn So Grammar::Tracer is SO good it not only helps you debug your grammar, but magically makes it work too? :P 15:29
masak no, it fails with a different failure.
guess that qualifies as a Heisenbug.
jnthn Well, more likely a Grammar::Tracer spoiling something bug...
masak I took a snapshot of the files -- will look at it later. 15:32
right now it would be a detour.
timotimo masak: could be an optimizer bug
oh, wait
yeah, maybe 15:33
masak no matter what the cause, it would be interesting to track it down.
timotimo some time ago i had to teach the optimizer to just ignore the kinds of nodes the debugger adds to regexes
otherwise it wouldn't turn a beginning-of-string anchor at the beginning into a direct fail instead of scanning through the whole string 15:34

Ulti smls yeah but you can't for the other ones so I wanted to be consistent 17:19
out parens on the if is a good call though
ok so in a grammar what is the syntax for an optional grouping of tokens 17:20
I have a feeling shoving a ? where I have isn't doing what I think it does
smls [ ... ]? 17:28
Ulti well that was fun :D 17:30
so this grammar for the advent cal is better than the one I've been using for a while lol
should probably improve the tests
smls Ulti: With «token record { ^^ ">" <id> [" "<comment> "\n"]? <sequence> }» it can parse the snippets from the FASTA wikipedia page 17:31
Ulti but yeah I didnt parse a FASTA without a comment before
so that was fun
smls yeah the idea is to have something a little more neat 17:32
perltricks gtodd: thx!
Ulti I also needed to change token to rule for the proto sequence bit because that obviously needs backtracking

smls Ulti: What makes you say that the 'sequence' proto token needs backtracking? 17:44
Ulti because otherwise it doesnt match all the sequence it could
smls It tries all overloads, and the one that matches the longest token wins, doesn't it?
Ulti so like if the start of a sequence looks like DNA it sort of gives up and ruins it 17:45
smls not with token
token its just I keep going along and if I could match something whatever the length it was that token
17:47 atroxaper joined
smls Hm. Are you sure? 17:50
Ulti sure in that its what I observed debugging it
I think its because of the proto 17:51
if it was three optional tokens it would work
<dna> | <rna> | <aa> as tokens that would do what you expect
17:51 atroxaper left
Ulti I guess proto tokens you want exact non confused tokens rather than something a bit more rule like 17:52
17:57 mr-foobar joined
smls Ulti: What do you gain from separating those rules in the first place? «token sequence:sym<aa> { <[A..Z\*\-\n]>+ }» already covers all cases... 18:01
Ulti nothing in that post ;P
but you could in theory attempt to create a different type of sequence object for each
smls m: grammar { rule TOP {<foo>+}; proto token foo {*}; token foo:sym<a> {a+}; token foo:sym<ab> {a b+} }.parse("aaababa").say 18:04

smls hm, looks like you're right, protos don't seem to work like | based LTM...
Ulti but they do as a rule 18:06
pun / actual wording intended
jnthn Ulti: Feel free to drop the feature request in the issues for Grammar::Debugger.
I want to revisit those two modules soon to get them able to use the method cache publishing support that I added to Rakudo in the last days, so they'll run a good bit faster. 18:07
Or rather, slow your grammar down a bit less :)
smls perlcabal.org/syn/S05.html#line_1349 suggests proto token should use longest-token matching though... 18:08
Ulti *shrug* for the sake of this post meh 18:09
smls I'm just trying to understand it all myself... :)
jnthn They do use LTM 18:11
That's the point of proto tokens... :)
the reason the one above doesn't match is that leftmost always wins
18:12 vaclavstrachon joined, vaclavstrachon is now known as wenca
jnthn That is, an a+ will eat as many as it can, and then a b+ won't have an a. And tokens don't backtrack. 18:12
smls so 'a b+' is not treated as a single token by LTM? 18:13
jnthn Sure, but
aaaaabb
At the start of the string, it a+ can match 18:14
So it eats all the as
Then the <foo>+ means we try to match <foo> again.
smls oh, right
jnthn But nothing does, 'cus we already ate every a
smls m: grammar { rule TOP {<foo>+}; proto token foo {*}; token foo:sym<a> {a+}; token foo:sym<ab> {a+ b+} }.parse("aaababa").say 18:15
camelia rakudo-moar 795a32: OUTPUT«｢aaababa｣␤ foo => ｢aaab｣␤ foo => ｢ab｣␤ foo => ｢a｣␤␤»
smls \o/
I wonder which of the two was chosen for the last 'a' there...
jnthn Has to be foo:sym<a>, because there's no b for the b+ to match, surely? 18:16
smls what if it was "a+ b*"
18:17 spider-mario joined
jnthn Same, but then LTM comes out the same and so it tie-breaks on declaration order. 18:17
18:17 tgt joined
vendethiel needs to rewrite his Text::Indented because it backtracks too much... 18:17
smls and the one that was declared earlier wins? 18:18
Ulti jnthn good thats how I was thinking about it too... so my mental model isnt totally bogus
smls yeah
at least thats what is happening
jnthn smls: Yeah; that's also how it's spec'd :) 18:19
perltricks is there a max identifier character length?
jnthn perltricks: Yes, you only have so much RAM/swap... :)
perltricks jnthn: heh ok, thanks 18:20
jnthn I'm pretty somebody (probably masak :P) tried out a megabyte long identifier once and it worked :P
*pretty sure
perltricks :D
smls Ulti: 18:21
still not convinced that your case needs backtracking though... :)
18:21 wenca left
smls Can you give an example of an input that only matches when you change proto token to proto rule there? 18:21
18:26 tgt left
jnthn smls: It's regex that backtracks, not rule 18:28
smls right
jnthn (sorry if that's not helpful info; I'm only half-following while I prepare dinner :)) 18:29
smls that makes it even more curious that changing "proto token" to "proto rule" apparently makes something work 18:30
in Ulti's grammar...
Especially since the candidates all consist of a single quantified character class, like «rule sequence:sym<rna> { <[ACGURYKMSWBDHVNX\-\n]>+ }» 18:33
So no significant whitespace for :sigspace to affect, except for the one before the closing brace.
jnthn I know that the char class has \n in it 18:34
18:34 rindolf left
smls Is that affected by :sigspace somehow? 18:35

raydiak it's a darn shame too, b/c there are also lots of cool people here, and easy access to some incredible nature, if outdoors is your thing, we even get all 4 seasons which I like 22:25
timotimo ;( 22:26
raydiak just too many elements being mixed under too much pressure in recent years maybe
but I could go on for hours about what I think is wrong with the world around me...I like Perl 6 (and #perl6) b/c it's one of the things that still feels more right than wrong :) 22:29

ab5tract everything i've been hacking on recently seems to break perl6 :( 22:37
one sequence, three or more outputs: gist.github.com/ab5tract/ff7ea75f0a9262d4e4a4
FROGGS_ ab5tract: that might be because of the BEGIN-block+our-scope design pattern 22:39
I bet the segfaults vanish with the removal of one of them 22:40
sorry that I've got to leave now though :/
gnight #perl6
timotimo gn
ab5tract ciao FROGGS_, thanks for the tip 22:41

ab5tract if removing the BEGIN block means making it a sub and calling it explicitly, that doesn't change anything :/ 22:46

ab5tract haven't been able to get undefined behavior or crashing with the same code on jvm, fwiw 22:48
22:49 atroxaper left
jnthn Looking at where it fails, I somewhat suspect the qq:x 22:51
The first one suggests some kind of heap corruption, and the second can be explained by corruption of the command given to tput
22:51 pyrimidine left
ab5tract jnthn: that's basically how i had broken it down in my reasoning. but i wouldn't have expected the RHS to affect the LHS in that way, re: the key behavior 22:53
i get those heap corruptions pretty consistently with qq:x on moar/os x
22:55 kurahaupo joined
jnthn Oh, you're on OS X... 22:55
ab5tract i thought to cache all the `tput cup y x` strings, and that for loop crashes ~90% of the time, but always in a different place, and with varying forms of "oh-noez-moar-splodes"
jnthn Yeah, there's some instability with moar on OSX that doesn't seem to exist on Windows or Linux. :( 22:56
ab5tract have you been having any luck with it?
jnthn I've spent hours on it already with lldb, guardmalloc, etc. I did find and fix two bugs. Sadly, neither seemed to be The Bug.
They helped get spectest cleaner, but something is certainly still amiss. 22:57
ab5tract :(
jnthn I should take a closer look at qqx. I wonder if it takes a different code path on OSX for some reason. 22:58
ab5tract do i understand correctly that OS X is swapping memory locations/values around?
jnthn Yeah, I suspect ASLR is to thank for the different outcomes between runs. 22:59
ab5tract jnthn: gist.github.com/ab5tract/28aa420074909a6925ae 23:00
that will get you a qq:x crash consistently, guaranteed
jnthn ooh
ab5tract "guaranteed consistency"
i've got to run for now 23:03
i hope it helps with your investigation
jnthn Sadly not on the OSX box I have access to but maybe I should update my Moar/Rakudo there first 23:04
I'll try on the train tomorrow
jnthn should probably sleep now-ish :)
ab5tract happy travels :) 23:05
23:05 ab5tract left
pmurias jnthn: sleeping is useful for hunting weird segfault ;) 23:06
