not so good for the benchmarks :S
t.h8.lv/p6bench/2014-06-18-all.html 10:27
kind of amazing that the concat benchmarks are in favor of moarvm; must be because of the excellent start-up time 10:28
interesting that rakudo-moar overtakes nqp-moar on the postwhile_nil_native benchmark 10:29

timotimo huh, 2013.06 rakudo-parrot starts up faster than current rakudo-moar does? o_O 10:34
ah, that was a cold cache vs a hot cache.

current rakudo-moar does say 1 in: 0.29user 0.03system 0:00.33elapsed 99%CPU (0avgtext+0avgdata 128308maxresident)k
(and perl5 does "say 1" in an unmeasurable amount of time and only 2 megabytes of ram, but that doesn't load any features ...) 10:50
hmm. startup speed and speed in general even before the jit kicks in is still a very valuable target if we want to offer our users a good tool for short commandline snippets. 10:51
not quite sure how fast our jit is going to kick in ...
i should have a look at the timezone thingie we do at startup time again; last time i looked it was responsible for a sizable chunk of start-up time. 10:53
get-local-timezone-offset, that is

donaldh There was me thinking that or was a synonym for ||
Spec says loose or
moritz my $x = Any or True;
is parsed as
(my $x = Any) or True
13:21 kaleem_ left
moritz that's the 'loose' 13:21
the precedence is looser than = 13:22
timotimo aye, if you want tighter or, you use ||
donaldh Yeah. It'll cause a lot of thinkos
timotimo it's for stuff like 'do some stuff or die "error!"'
moritz donaldh: it's actually for preventing a big class of thinkos
my $res = dostuff or die "OH NOEZ" 13:23
donaldh: the knowledge when to use || vs. or is carried in idioms
donaldh Yep. 13:24
thx

13:26 Alina-malina joined
moritz donaldh++ 13:27
actually that's something that could warn
useless use of 'or' in sink context
masak aye. 13:29
my pragmatic rule is that I use the symbol forms whenever I'm dealing with expressions, and the word forms whenever I'm dealing with statements.
that's a simplification, but it seems to hold up.
moritz ... but only if the RHS is a constant expression
(re warning) 13:30
masak oh?
moritz my $x = open(...) or die "blerg!" 13:31
shouldn't warn about useless use of 'or'
masak doesn't have more to do with side effects than with constancy?
a referentially transparent function call would also be quite useless.
moritz aye, but that would be constant-folded, I believe 13:32
masak: for a specification POV, you're right that it's about side effects 13:33
masak: but we can only know that an expression is free of side effects when it's a pure expression or a constant
masak *nod*
moritz (so far)
moritz whistles some tunes from Knutsen&Ludvigsen 13:37
donaldh I recall there was a discussion about install layout a few days ago but I cannot find it. 13:39
Did anyone make a proposal for a better layout, rather than just following what parrot does?
13:42 mmcleric joined
FROGGS donaldh: there in an nqp issue about that 13:43
donaldh FROGGS: This one? github.com/perl6/nqp/issues/154 13:47
On JVM it would be good to separate the Java classpath from the module lookup. During bootstrap, nqp relies on the Java classpath containing module directories. 13:48
I'm looking at this just now so could work on a better layout at the same time. 13:49
Also don't know whether it is stylistically better to have -D options for the JVM or add command-line options to nqp and perl6 13:50
I guess if the solution is JVM specific then -D might be preferred. But if it's something shared by backends then it should be a command-line option.
FROGGS donaldh: yes, that one

hoelzro so I did most of the change for $*PROGRAM_NAME -> $*PROGRAM last night 15:27
but I got stuck when it came time to figure out what it means to assign to $*PROGRAM
how should that work?

atroxaper_ Sorry, but I have one more question... If I have function with Junction like q[sub a(:$d where {$d > 2}) {}] and have q[my %h ={d => 3}]. How can I check that %h satisfies &a ? I thought about getting a Junction from each parameter of &a and check. But I don't know what can I do with Junction and value xD 15:50

psch yeah, looks good i think :) 15:57

should be 0x01FF?
atroxaper_ psch: why does it works only in % ~~ & order? And doesn't work in & ~~ % order....
psch atroxaper_: that's semantics of ~~. it checks if the rhs accepts the lhs 16:02

er, areas
jdv79: and there are a few Advent articles on grammars: perl6advent.wordpress.com/?s=grammar 17:09
vendethiel just convinced a friend that p6 is more elegant than ruby
PerlJam vendethiel: even with the funny symbols? (those always seem to be a contentious item for some people) 17:10
vendethiel PerlJam: I convinced him thanks to static type (and hence names) checks
jdv79 thanks 17:12
how does perf compare to the perl5 regex engine?
PerlJam jdv79: slower but way more powerful (IMHO)
jdv79 the p5 module i'm looking to parse is pretty fast and it get a lot of that from leveraging the regex engine
s/parse/port/ 17:13
vendethiel Slow, yet :P
jdv79 ok, still slower. i thought since its so core to p6 it might be on a faster track in terms of perf.
vendethiel s/Slow,/Not fast,not/
jdv79: perl 6 is not finished ... especially performance-wise ... even if we're making great progress on that :) 17:14
PerlJam jdv79: If you had something that used P5's Parse::RecDescent, you may see a performance boost by porting it to P6 grammars ;-) 17:17
nwc10 iiiinteresting
is it viable to make a convertor from Parse::RecDescent to Perl 6 rules?
has Damian done that yet? 17:18
vendethiel PerlJam: really ?
PerlJam vendethiel: maybe. I haven't kept up with changes to PArse::RecDescent, but the last time I used it, it was quite slow. 17:19

jdv79 its using a combo of a recursive regex and hand built code to do the parsing. 17:35
its also using the regex engine to do the application but i forget exactly how
anyway, lots of good info - thanks
i was going to try to use Conway's new parser, I think its Regexp::Grammars, but at the time p5 broke it so I didn't look into it. 17:36

segomos_ jnthn: i discovered that if i do $*SCHEDULER.load that with one request i end up with '16' as the .load and that all processing ceases, is there something i can do to increase that number or handle whatever is going on in $*SCHEDULER and resume processing? 18:14
PerlJam y 18:15
ww
jnthn segomos_: Hm, I think 16 is the max number of threads. That implies that somehow they all hung... 18:18
But that sounds odd.
Can try putting a ThreadPoolScheduler instance into $*SCHEDULER at program start with a higher max threads... 18:19
segomos_ i'll give it a shot 18:20
that makes the jvm work, i need to test to see if i'm leaking promises or something else is happening 18:24
masak someone who did a convertor from Parse::RecDescent to Perl 6 would hit the following roadblock: the data hierarchies returned (in %/ and $/, respectively) are different, and automatically porting access into them is probably Hard. 18:40
timotimo aaw :( 18:41
is there something that's inherently better about the RecDescent structure?
18:42 parsus joined
masak yes, I felt that when I was using it. 18:43
but it was a long time ago.
18:47 zakharyas left
timotimo it could be possible to build a recdescent-compatible parser in nqp, no? 18:47
18:47 dwarring joined 18:53 denis_boyun_ joined
nwc10 timotimo: yes, until you get to this bit: metacpan.org/pod/Parse::RecDescent#Actions 18:56
An action is a block of Perl code which is to be executed (as the block of a do statement) when the parser reaches that point in a production.
so you're getting to V5 territory
but it might just fly
18:58 denis_boyun___ joined, denis_boyun_ left
nwc10 in that, it might stand a chance as a 90% solution, as my hunch is that the code within typical actions wouldn't be excessively "funky", so stands a fighting chance of being parsed by V5 19:00
masak aye.
I'm bummed that we don't have a good story for re-entrant regex matching, whether in code blocks in regexes or in action methods for grammars. 19:01
at least one of us should have seen that one coming. I believe the spec is entirely silent on the matter.
19:02 atroxaper joined 19:04 denis_boyun___ left
nwc10 masak: which means that the default is "like Perl 5 does", which is, oh, wait... 19:04

PerlJam somethign that turned the grammary bits of a P::RD grammar into a P6 grammar and stubbed out places where code should go would be a good start probably. 19:16
then all we'd need would be a good p5 -> p6 converter ;)
segomos_ jnthn: is there a limit to the number of threads in the queue? 19:17
PerlJam (or, as soon as v5 is fully formed, we'd just copy the p5 code block directly into the p6 code block with a "use v5;" at the front 19:19
)
