I'll send rakudobug an email about it. 12:58
done. 13:01
pmurias masak: i *could* add .:e support to mildew but it's not exactly on the ROADMAP right now 13:10
masak pmurias: not asking you to. :)
I'm just thinking along these lines because I added "file" ~~ :e support to Rakudo yesterday
pmurias: btw, I hear this 'mildew' name being dropped all the time nowadays. I thought you guys were building sm0p and m0ld and stuff. where does mildew fit into the picture? 13:11

mildew is our perl6 compiler
masak nice
what does it compile to?
pmurias m0ld
masak :)
which is...? 13:15
pmurias the assembler
masak so, sort of like PIR?
pmurias yes
with a perl6 syntax and 4 opcodes
masak is Perl 5 compatibility on the ROADMAP? 13:16

ruoso yes
I even removed build and m0ld/dist
and rebuilt everything 13:36
including './Setup configure --flags=SMOP; ./Setup build'
inside m0ld
13:36 alanhaggai joined
pmurias it works here, maybe i have old something 13:37
you could nopaste perl mildew --file t/variable_declaration.p6 --desugar 13:40
i rebuild STD, rm -fr lex and rm -fr build;make in smop and it prints output
ruoso ok... let me rebuild STD 13:41
pmurias btw t/variable_declaration.p6 is a different test
ruoso yeah... I know...
pmurias++ # rebuilding STD works 13:43
pmurias something like gobby for shells would be nice
ruoso we could have the evalbot updated to use mildew instead of pugs for smop 13:45
that's very cool 13:46
because we're actually using STD as the parser for SMOP 13:47
pmurias i'm not really sure how do procced with adding a new evalbot backend 13:54
ruoso pmurias, at first we could have mildew optionally accepting STDIN 13:55

pmurias TimToady: mildew executing a single test takes ~1.0 sec 17:05
[bobrik]: if it's empty for you propably have a broken checkout
TimToady: i could use joint compilation for tests if they become to numerous (>30) 17:10
[bobrik] pmurias: `emerge parrot` 17:12

pmurias: how did you install that?
pmurias you should propably checkout parrot from version control and build it yourself

moritz_ pmurias: re mildew, what do I need to run it? 17:18
pmurias moritz_: perl mildew --exec --file file
moritz_ pmurias: does it need write access anywhereƟ 17:19
s/Ɵ/?/
pmurias lex propably
moritz_ v6/mildew/lex?
pmurias and you need to compile m0ld v6/smop/m0ld with ./Setup configure --flags=SMOP;./Setup build
yes
it's STD based
moritz_ @tell azawawi go right ahead ;) 17:21
lambdabot Consider it noted.

pmurias moritz_: you did it for pixie right?
moritz_ pmurias: no, but for STD.pm 17:25
pmurias pixie: say 1
p6eval pixie: No output (you need to produce output to STDOUT)
pmurias pixie: 1
p6eval pixie: No output (you need to produce output to STDOUT)
moritz_ does pixie re-use STD.pm's lex cache?
17:25 ruoso_ joined
pmurias don't remember, pixie is not important 17:26
moritz_ ok ;)
is it still developed?
pmurias no
moritz_ then I'll rip it out of evalbot

ruoso .oO( doing maintainance on laptops sucks ) 17:28
pmurias ruoso: you are aware we fake stacklessness for other interpreters by saving an restoring the stack in an unportable manner? 17:29
ruoso what do you mean? 17:30
pmurias s/an/and 17:31
ruoso: it's possible to save the C stack if we are willing to resort to assembler
ruoso we don't even need to go to assembler
C99 specs longjmp
ruoso wonders if pmurias meant "aware that we *could* fake" 17:32
pmurias yes 17:34
ruoso yes... I'm aware of that.. and in fact... that is probably a good way to provide p5 XS integration
that subject was discussed this week
about getting p5 XS macros and changing it when building the SMOP p5 interpreter 17:35
and subverting the current XS macros to do this kind of hack
TimToady even said that was the ponie idea
considering SMOP p5 would require a recompilation of binary modules... which seems just fine... 17:36
pmurias why would we need to change the XS macroes?
ruoso because the C code inside XS modules might be recursing on the p5 interpreter using the C stack 17:37
so we would need to change the macros so that instead of doing the call, it would save the current stack and recurse without using the C stack
in fact... this trick could be used to remove current p5 non-stacklessness 17:40
17:44 FireMinion joined
pmurias ruoso: can longjump also "rewind" the stack or only unwind it? 17:46
ruoso pmurias, setjmp is the reverse
pmurias, are you aware that the latest changes broke tests in smop? 17:48
pmurias hm, checking 17:49
ruoso pmurias, it looks ".^!how()" in p6opaque is not working as expected 17:50

pugs_svn r22654 | moritz++ | [docs/tutorial] (aka book) many clean ups and enhancements to ch07_grammars.pod. 17:56

r22655 | pmurias++ | [smop] fixed failing p6opaque tests
ruoso pmurias, I'm not sure the recusion in p6opaque is a good idea 17:57
that ckecing should probably be made inside the sm0p block (which could be translated to m0ld) 17:58
we even have the ri test already 17:59
pmurias propably, it wouldn't change anything the way p6opaque is currently implemented
ruoso pmurias, do I translate it to m0ld or you do it? 18:00

* STD5_dump_match
moritz_ pmurias: probably, but I didn't grok the code :/ 18:14
pmurias traverse_match creates an array of events (like rule starts, rule ends) and process_events executes them in the order of their positions in the source file 18:16
18:16 pedrob joined 18:17 pedrob_ joined
pmurias moritz_: it should become clearer if you what the $events passed to traverse_match contains after the topmost traverse_match finishes 18:17
literal moritz_: I see a few typos, "simple most solution" (most simple solution) and "hybernating"/"hybernates" (hibernating/hibernates), "agend" (agenda) 18:18
moritz_ literal: thanks, fixed 18:19
pmurias moritz_: and you didn't mention that smop now uses viv ;)
moritz_ pmurias: does it? how? through mildew?
pmurias: just write a paragraph or two about it, and I'll add them to the page 18:20
pmurias yes, mildew uses viv

pmurias SMOP now has a new compiler mildew which uses viv/STD as it's parser. 18:31
Mildew supports only a handfull of stuff now (creating an object with a simpilified meta model being the most advanced one)
is the most i came up with ;)
moritz_ pmurias: ok, updated the post 18:35
it now reads "SMOP now has a new compiler named mildew which uses viv/STD as its parser. Right now it supports only a handfull of operations, the most advanced of it is creating an object with a simplified meta model.

18:54 pasteling joined
moritz_ that should work, I think 18:54
azawawi moritz_: the problem is that the type is not provided in the yaml output 18:55
moritz_ azawawi: I don't think you need to actually care about the yaml or json thing... take a look at the `tryfile' script 18:57
instead of Dump($r) in the last line you can work with $r directly

pmurias we can compile a custom STD 21:03
moritz_ I think TimToady will be interested in solving that problem soon too 21:05
azawawi i think it can also be detected without any STD.pm change... looking at the html output 21:06
pmurias azawawi: you mean doing manual reparsing of the whitespace?
moritz_ pmurias: not re-parsing... but everything that's not matched by any rule got to be a whitespace 21:07
azawawi pmurias: when all spans are closed, that's a whitespace
azawawi testing this theory
pmurias moritz_: everything is matched by topmost rule 21:08
pugs_svn r22659 | moritz++ | [STD_syntax_highlight] HTML-Escape <>&". Add a few CSS classes.
