bbkr hi, i need to debug some grammar and print the captures value from token. but "token foo { someregex <{ say $1 }> }" syntax returns parse error on today's SVN rakudo. what am i doing wrong here? 00:11

[particle] bbkr: try using .panic. <{...}> isn't implemented in rakudo yet 00:43
bbkr how to use it? it compiles but doesn't print anything 00:47
S05 only describes "The new :panic modifier causes this regex and all invoked subrules to try to backtrack on any rules that would otherwise default to not backtracking" .... 00:49
i guess it's not what you mean?
some other method to print whole parsed tree would also be sufficient 00:51
[particle] <panic: "foo bar"> iirc 00:52
it'll end there, though 00:53
if you want to inspect your parse tree, you can pass --target=parse to perl6.pbc
seems from rereading your question, that is what you really want 00:54

bbkr something is wrong with today's SVN version (it ain't matching basic grammar). i switched to 0.71 release but there it says - "Unable to find regex 'panic'". i'll try this --target option 01:00
and what i really want to do is to write some *.ini to hash mapping just like in PERL5 Parse::RecDescent or Parse::Eyapp where some code can be executed on token match... looks like Rakudo is not mature enough yet :( 01:04
mberends bbkr: if today's Rakudo is broken for regex don't despair - regression testing will restore it soon. Have a read of the November wiki engine for some examples of Rakudo regex in action... 01:08

lambdabot Title: Permutations and combinations
04:03 mj41_ left
eternaleye Nope, on running it, it seems that it does the same thing as mine except that the acceptable characters list for each position are passed in as a separate arrayref. I'll keep looking. 04:04
Doesn't look like there's anything specific to Perl 6 out there to permute a list. The examples in recipe 4.19 of the Perl [5] Cookbook shouldn't be too far from valid Perl 6, but there are probably ways to make a Perl 6 implementation more terse. (Perl 6 seems to be good at terseness - like the oneliner above that does nested loops) 04:19
literal perhaps check out Algorithm::Permute and try to make a Perl 6 one-liner out of it :P 04:28

moritz_ wonders if t/spec/S05-modifier/ignorecase.t is actually correct 12:29
it assumes that a :i has recursive meaning in subrules
I don't think that's the case.
12:29 iblechbot joined
moritz_ wonders why it takes so many rules to match variables 12:31
azawawi "The :i (or :ignorecase) modifier causes case distinctions to be ignored in its lexical scope, but not in its dynamic scope. That is, subrules always use their own case settings."
moritz_ right, that's what I had in mind.
literal moritz_: does the '...' construct have Unicode shorthand of 'ā€¦' in Perl 6? 12:32
12:32 pedrob joined
pugs_svn r22667 | moritz++ | [STD_syntax_highlight] some color changes/additions 12:32
moritz_ azawawi: I like the match tree in the html output ;) 12:33
literal: not that I'm aware of
literal: I think most "Unicode" builtins actually map to Latin-1, like Ā«...Ā»
literal I don't think ā€¦ is in Latin-1, though 12:34
moritz_ aye
literal why would that be a problem, though? 12:35
moritz_ it wouldn't
&infix:<ā€¦> ::= &infix<...> # eh voila!
literal ... is also used as a code placeholder in methods, right? 12:36
moritz_ yes
azawawi moritz_: what's the perl6 program that uses most of the perl6 syntax [to be used as a test case for syntax highlighting]
moritz_ but I think it's not an infix in that case
azawawi: STD.pm 12:37
azawawi moritz_: i think we should re-organize src/perl6 into src/perl6/highlighter or something like that 12:38
moritz_ azawawi: yes, but that's premature optimization ;)

moritz_ indeed
and azawawi++ for implementing it ;)
14:17 alester joined
moritz_ it's nice, even interpolated variables are coloured correctly 14:19
azawawi being generic can sometimes have its merits ;-) 14:20
so STD.pm is the perfect perl6 script that uses most of the grammar 14:21
moritz_ not quite
but it's one of the biggest nonetheless
doesn't use meta ops, for example

pmurias ruoso: multis could be implemented in p6, couldn't they? 15:23
ruoso pmurias, yes... they could
pmurias, in fact, if not in p6, at least in m0ld 15:24
in C it's very unlikely to be doable
but it's basically $s1p_multi.()
where the $multi holds some variants and a pointer to its outer scope 15:25
and its name
15:25 zamolxes joined
pmurias it's better to do stuff in p6 then in m0ld 15:25
ruoso then it goes traversing the scopes to find all variants
grep { $_.signature.ACCEPTS($capture) }, @variants 15:26
ruoso lunch &
pmurias why does it need to traverse scopes it can just hold a pointer to the outer variant 15:27

lambdabot Title: Official Perl 6 Documentation
azawawi pmurias: gr8 idea 16:54
moritz_ and before somebody asks - that page is generated by util/smartlinks.pl ;) 16:55
azawawi pmurias: where is the code that does the smartlinking and syn stuff?
moritz_: lol
moritz_: judging from speed of things, we need to have a smart update of the html output... 16:57
moritz_ I wouldn't add more stuff the the S\d\d.html pages themselves, they are already rather heavy-weight (and take some time to load on slow browsers) 16:58
azawawi moritz_: we dont wanna slow down your precious ;-)
moritz_ rather add a link to an index of the syntax hilighted files
azawawi moritz_: ajax comes to the rescue...
[particle] ajax++
pmurias moritz_: slow browser = slow internet connections? 16:59
[particle] it'd be nice to have syntax-highlighted examples and inlined tests

ajax only makes that worse
azawawi i think we could cut a lot of fat from the Sxx pages when we ajax them

pmurias azawawi: your answer was a bit contradictory 17:12
azawawi sorry i was looking at something else
im not going to optimize js
pmurias ok
azawawi the key thing here is updating output html when the spec file is changed and putting the output on a webserver... 17:14
i.e. when the test .t is actually changed, generate the html 17:15

TimToady well, the fact of the matter is that as long as STD is implemented in P5, we have to compile close to 3 megabytes of P5 code to start up. 17:19

pmurias TimToady: TRE leaks memory so running a persistent STD is not really an option
CD 17:22
sorry
(caps lock--)
TimToady it really depends on how TRE leaks memory 17:24
pmurias having checked it in a while put when i run a persistent STD a long time before it eat >2G of it and segfaulted 17:25
TimToady we can cut out 1meg of whitespace by making gimme5's indent an identity function 17:26
it would appear that it still works after that
Cursor caches all lexers it has ever generated, so maybe you were seeing that 17:27
pmurias maybe, the TRE using part is the one i don't undestand much so it's likely i just blamed the leaks on the unknown ;) 17:28
TimToady (at the moment I'm working on cutting down the number of lexers it needs to build, so we can have a series of macros efficiently)
oops, gotta commute to work right now & 17:29
azawawi pmurias: t/spec/S05-mass/rx.t is the worst case so far [455m memory] 17:31
pmurias the memory used or the size of the highlighted output?
azawawi it is virt memory used; the output is flushed at the end 17:32
17:48 meppl joined
azawawi has anyone tried to run t/spec/S05-mass/rx.t with STD? does it ever finish? 18:04
TimToady certainly
STD parses everything in t
azawawi time estimate?
TimToady hang on (in a meeting) 18:05
azawawi ok 18:06
TimToady if lex cache already exists, 27 seconds on my machine. 2-3 times longer if it has to generate lexers 18:08
are you short on memory?
azawawi feather1... dont think so

TimToady if you're using something that traverses the std tree, could well have an infinite loop in it 18:10
azawawi it is basically stuck at 460mb virtual memory and just continues to eat CPU 18:11
63:21.06 cpu time so far...
TimToady you've gotta be looping somehow then 18:12
azawawi and yes it is traversing the std tree to generate the syntax hilighted html... 18:13
TimToady some of the routines in Cursor like ->clean are known to have infinite loops for some inputs
are you using STD directly or viv?
azawawi STD and DumpMatch 18:14
directly i guess since i dont know the other one ;-)

pmurias TimToady: it's a STD5_dump_match mutant 18:18

maybe set STD5DEBUG=-1 to get debugging log to screen 18:20

lines,bytes
TimToady well, the .t is 2720 lines 18:29
pmurias js and stuff
we could always rewrite parts of STD_syntax_highlight in C... 18:31
TimToady it's a trivial change to Cursor to map positions to what reductions were done at that position, since the _ array is already indexed by position
18:33 zamolxes_ left 18:36 Bzek left 18:40 pedrob left
TimToady so it would be easy to implement a scan of positions that were not matched by any subrule of the current rule 18:41
18:45 ruoso joined
pmurias ruoso: do you think multis are necessary for P6Meta? 18:54
ruoso pmurias, well... we could have some only subs installed in the prelude scope for it to work
and then we could overwrite it
pmurias, one thing I've been thinking is how to build the src-s1p files... 18:55
and I think we should have a .so file built for each .pm file 18:56
with two methods in its api
init_order() and initialize()
then smop would find all .so files in the s1p directory, load them, sort by init_order and call initialize in each one of them...
pugs_svn r22681 | ruoso++ | [smop] we dont really need feed or gather/take in P6Meta.can 19:03
19:05 explorer joined
pmurias ruoso: alternatively we could link the haskell m0ld parser in and use it to dynamicly load .m0ld files in 19:07
ruoso pmurias, I'm not sure about that... because I do think the s1p part will always be compiled down to C 19:08
or else it will mean parsing the prelude *everytime*
azawawi pmurias: nearly finished, processing S29-scalar ;-)
ruoso which doesn't seem optimal

azawawi but dont go to rx.html... it will break the 15-second time for sure...
pmurias: will fix it soon 19:38

azawawi what browser r u using? 19:39
ruoso firefox
azawawi 3?
ruoso yesajh
S02-builtin_data_types/nested_arrays.html
this one is a heavy one
pmurias azawawi: i went to rx.html but the tooltip is a bit sluggish 19:40
ruoso yeah... I think the tooltip needs a different visualization 19:41
maybe not being a tooltip
but rather a side tree
azawawi it was a side tree in the beginning ;-)
ruoso that you can expand and see the referring code
azawawi but somebody thought it was a good idea to make it a tooltip ;-) 19:42
ruoso heh...
azawawi for scrolling reasons
ruoso make it collapsed by default
and the user goes expanding it as pleased
and while the user expands it the referring code for that node of the tree is highlighted 19:43

azawawi got it... side tree... on expand hilight... 19:43
pmurias: do u think getting pod comments in the syntax tree a bit too much? 19:46
pmurias it would mean using a modified STD 19:47
azawawi: do you think it's important?
azawawi not that much 19:48
i think being able to see a syntax tree visually is way more important
pmurias pod doesn't require very much highlighting 19:49
azawawi google chrome (chromium) dev release does not run rx.html well
memory keeps rising on its tab 19:50
but after a while, tooltip is way too fast on chrome compared to firefox 19:53
must be the inlining/caching that have in their v8 engine

but only -c -h -e -v 23:02
literal ok 23:03
will code executed with -e be treated the same as code from a file? i.e. same level of strictness 23:04
[particle] yes
literal ok
[particle] you need -e6 to turn off strict, which is not implemented
literal ok
is the "loose mode" discussed anywhere in the synopses? 23:05
[particle] yes, search for e6
apparently it's mentioned in S11 23:06

literal yeah, I knew about that

literal but I was wondering if there will be a strict pragma so that you could turn of some strictures manually
23:14 FurnaceBoy left
literal ah 23:14
[particle] yes, there will be a way to adjust strictures and warnings by category 23:15
TimToady the only one you could possibly have from p5 is 'vars', since refs and syms aren't handled the same way in p6 23:16
literal has there been any discussion about pragmas? I see there's no apocalypse/synopsis draft
TimToady there are a few pragmas mentioned here or there, but generally we considered the need for a pragma to be a design smell 23:17
literal I see
TimToady there's a general principle that if you're going to have a pragma that modifies a builtin with keyword "foo", the pragma should also be named "foo"
23:18 eternaleye joined
TimToady "use open :x" modifies the meaning of open(), for instance 23:18
