mncharity tamarin would be nifty, but doesn't seem quite ready for primetime... and might have to tweak JavaScripdt::SpiderMonkey to work iwth it... but js 1.7 or 1.8 could be fun, though not a speedup... :/ 01:38
diakopter: does :) indicates presence of interest... 01:39
doesn't seem plausible to attempt anything statically typed at this point... 01:40
at least for bootstrap. might perhaps compile down "lots of function calling", eg, parser, to Inline::C... 01:41

mncharity re 'svn up'... doesn't do much yet. just hacked it to take 'sub f($x){say $x+3} f(4)' and print 7. Mostly just getting the setup in place. 03:55
03:58 alc joined
mncharity spinclad: re scheme, on my todo list after 'full bootstrap with STD_red translated into p6 and absorbed into elf, and elf running on at least two backends', is to start pushing on frontends. First a js, but then a scheme. Thinking of bigloo, just because it has a regexp-like reader design. 04:03
but if someone was interested in pursuing it, we could start sooner, even now. 04:04
re T, shudder. Worked on overhauling the T manual years ago. Became a "if the client asks for something insane, push back or leave" life lesson. 04:06

lambdabot Title: Changeset 20741 - Pugs - Trac
diakopter no it doesn't; it's blockquoting the indented areas 07:03
moritz_ ok 07:04
diakopter anyway, the nthru operator overloads symbol "..."
oh, and match() will take qr// patterns and match them against input 07:05
which will offer very easy shortcut creation for helping one() rule out branches quickly 07:06
where one() is the old alternate()
07:06 justatheory left
diakopter btw, I realized that backtracking recursive descent parsers like this one already do LTM, as long as you write your grammar correctly. the branch that matches the entire input wins. you just have to make all your recursive nonterminals right-recursive instead of left. Though tonight I will think about how to write a parser constructor to help you with that. 07:09
pugs_svnbot r20742 | lwall++ | [STD5] can now parse radix.t
moritz_ can parse radix.t - is that a good or a bad sign? ;-)
diakopter also you have to specify as greedy things that should be greedy.
moritz_ (given the current shape of our test suite, that is ;)
diakopter oh, and, the memoizing is essentially constructing a DFA as it goes... 07:10
TimToady it's more than STD5 was ever able to parse before, so I think it's good
moritz_ diakopter: why are you non-greedy by default?
ok TimToady++
diakopter moritz_: b/c you can't be greedy by default...? I mean, what if a repeated pattern signifies the start of a new pattern 07:11
moritz_ diakopter: example?
diakopter well, in writing the grammar you're specifying legal input as well as writing parsing instructions. 07:12
so you don't want to allow repeated patterns where the language doesn't allow them.. like } at the end of a block - you don't want to have it accept an unbalanced extra } 07:13
oh, sorry; I meant a different greedy 07:14
moritz_ in which case you wouldn't use a quantifier at all, which makes the distinction between "greedy" and "non-greedy" useless
ah ok
diakopter to restate, I meant to say that where a pattern can be recursive, the other things inside it should be as greedy as possible, to prevent non-LTM 07:16
in other words, make sure the grammar covers all possible legal syntax :D
in other words, write a correct grammar 07:17
heh
moritz_ ;)

diakopter a few more things to be fully packrat-ified: get rid of the 3 remaining character classes; finish the match() parser generator to accept p5 REs so character classes are a lot easier; add an explicit normalizer function parameter to memoize() to ensure $input is keyed correctly in the memo tables. 13:52
oh and, rip out the lexer component entirely so that it's a lot simpler. also requires changes to the two terminals hit() and eoi() 13:53

there is a term... i'm trying to remember it
gotta look at the ::(...) op i think
Auzon The spec mentions something like indirect
[particle] ah, right
indirect method call
16:45 nipotaway is now known as nipotan
Auzon but that's confusing with the indirect syntax, e.g. bar $foo: 1,2,3 16:45
TimToady that's the "indirect object" syntax
Auzon Ah, ok.
[particle] ut oh
$bar $foo: 1,2,3 16:46
TimToady not allowed
[particle] stated in spec?
TimToady that's two terms in a row
[particle] ok, that should be tested

TimToady 4 seconds here
but some of that is dumping the result
pmurias but works and that's important ;)
TimToady important points: it's doing true LTM and true language switching 17:00
true LTM modulo bugs like aa|a
but that's really only an issue under non-ratchet 17:02
so I'm not worrying about it until we get better laziness
not sure what to do next
get regexes parsing maybe
or work on lazy list semantics in p5 so I don't have to care about things like .* generating a list for the whole rest of the string 17:03
(and presumably fix the aa|a bug at the same time)
but I think regex parsing is more applicable to getting STD to parse STD at this point 17:04
since, for some reason, STD seems to use a lot of regexen... 17:05

kolibrie TimToady: if I had a grammar to parse a conference schedule, I could compile that into perl 5 with gimme5. Is there a way to run it against an input file? 18:08
kolibrie is thinking about starting to prepare to update his talk for next week: feather.perl6.nl/~kolibrie/extraction.xul 18:10
kolibrie wants to be able to field questions regarding how to use: pugs, PCR, kp6, STD, elf, rakudo, (and what about smop and yap6) 18:13
pmurias smop and elf don't support much perl6 rules yet 18:23
TimToady kolibrie: see my recent nopaste 18:24
kolibrie TimToady: I was trying to figure out how to use that for this scenario, but my brain did not wrap far enough 18:25
TimToady you're basically talking about using something else where that program uses STD5 18:26
but if you want to feed something directly to gimme5, you'll need to make sure it is in a form that it can handle 18:27
because it's not actually doing a real parse on its input
so the } at the end of a grammar must be marked with # end grammar, for instance 18:28
kolibrie I got what appears to be perl 5 code at the top with a data structure at the bottom
TimToady it does do a real parse on the rules
the data structure is the parse of those rules 18:29
mostly used by the LTM to determine the longest token
kolibrie so if I only have rules, it should parse fine
TimToady what happens when you run it
?
well, you'll probably need to write something that uses it like the nopast 18:30
kolibrie right, so that is the next step
I think that 'comp_unit' becomes whatever my toplevel rule is
and 'try.t' becomes my input file
TimToady yes, and change Perl-> to whatever your grammar name is
kolibrie aha - I was trying to figure out where that came from 18:31
TimToady eventually we'll probably have one more step there where you have to say Perl->new->parse() so that we have a mutable grammar object, but for now, that's the incantation 18:32
kolibrie thank you so much. I'll play with this for a bit and get back to you (I have to play with real $work a bit too) 18:33
TimToady it's quite likely to blow up
kolibrie I'll stand a few feet away
pmurias @tell mncharity elf breaks with the newest autobox 18:34
lambdabot Consider it noted.
pmurias TimToady: gimme5 hardcodes grammar Perl 18:36

diakopter TimToady: it's identical to <?before ...> I think 19:21
which means <!before <something>> and <!something> can be translated to it
but not the capturing one...
actually, the capturing one can be done too 19:22
the combinated parser would just create/publish its own new parser coderef under some keyed name 19:23
and then send it on through to the continuation using eval 19:24
hmm; lookbehind... currently it's constructing the AST only on the way back from the EOI, but I guess it can construct it on its way there too/instead, so that lookbehind could work. 19:26
but the RE hints, esp in the nbexpr (non-block expression) rule, would really help efficiency I think. 19:27
TimToady EOI? 19:28
the way the LTM works, it uses the contents of <?before> as the token and ignores what follows 19:29
diakopter end of input
TimToady while <!before> is just the opposite
diakopter oh ok 19:30
TimToady I don't understand what constructing the AST has to do with lookbehind
it's just matching backwards
see all the *rev methods in Cursor5 for its implementation of <after> 19:32
diakopter well currently the input is stored as nested arrayrefs/characters which are chewed up destructively as a heretofore successful path is taken, so that would need redone to support lookbehind (since right now there's nothing to look for backwards)
TimToady ah, Cursor5 just uses pos on an immutable input string 19:33
19:33 barney left
TimToady actually, the real pos is passed around via the continuations 19:33
diakopter ok. that's what I'll choose as well then
it's not like someone is going to give us a 512MB input string 19:34
well, STD5.pm is close
TimToady I suspect I'll eventually need to move to scalar contexts and iterators instead of list contexts
19:35 TJCRI left
TimToady unless I can figure out an easy way for p5 to support lazy lists outside of tied arrays 19:35
most of the time you can get away with p5's eager lists under ratchet mode 19:36
since you're always just throwing away all but the first value of the list
diakopter is an <?after > literally applied in reverse? as if the whole content string is inverted? or are ^ and $ effectively swapped
TimToady but as I mentioned earlier, .* would be a problem, since it would eagerly generate all the continuations from here to the end of the input 19:37
nothing changes meaning, but the pattern is matched from the back end
some patterns are not reversible
diakopter there are algorithms to convert left recursion to right recursion... I though?
thought
TimToady well, anything is better than p5's limitation of literal strings only 19:38
and it's completely impractical to try to rescan in the forward direction
so I guess at some point the implementations will have to come to some rough agreement on what is reversible and what isn't 19:39
STD5's implementation is a good first approximation though
if you say <?after ^^ .* $$> it will match the $$, then the .* backwards till it finds a ^^ 19:40
well, modulo the .* problem I mentioned. You'd probably want to write \N* there for now 19:41
or .*?
though that will try to generate all the possibilities under eager lists 19:42
diakopter well currently I put a self-recursion depth limitation (depth charge) on every parser for every input position
TimToady originally gimme5/metholate targeted pugs with gather/take, which is (in theory) lazy 19:43
diakopter and it's set to 2
so if the exact same parser (rule) is called on the exact same input more than twice, it fails that branch 19:44
... at least I think we're talking about the same thing.
19:46 rindolf joined
TimToady if your LTM is really working right it should detect recursion without progress most of the time 19:46
as long as your longest token is non-zero length, you make progress, pretty much guaranteed 19:47
19:47 Gothmog_ left
diakopter well that's the method $cdepth->{$magical_eta_conversion_parser_self_reference}->{$input arrayref, though it should be changed to flattened string} ++ for each new depth 19:48
where cdepth used to mean concatenation depth before I renamed concatenation to all(), which recurses down to both()
yeah; as long as it escapes infinite recursion (and the grammar is encoded correctly), it will eventually match the entire input correctly or fail at some point b/c the input doesn't fit the grammar's language 19:50
and I think I've implemented the memoization correctly so that it can act in linear time instead of exponential like most top-down/rd parsers 19:51
19:51 Gothmog_ joined
diakopter at least according to the paper on packrat parsing 19:53

was going through this article though sometime back and also installed PERL6 in my system

diakopter thought of another combinator: of(3..5,rulename) hits only if there are between 3 and 5 repititions of rulename, inclusively 20:24

lambdabot Title: Parrot - Perl&#039;s new Virtual Machine, tinyurl.com/57gmhh
diakopter not sure how helpful that will be though
pugpuppy so any ideas on which materials to refer to
Auzon What are you hoping to do? 20:25
pugpuppy well contributing to PERL6 development
Auzon What languages do you know? 20:26
pugpuppy this will be first time that I will actually be contributing to any community so you can really imagine me as a real puppy (though a very enthusiastic one and wagging tail and all that )
PERL, C, VBA, PHP
learning bits and pieces of JAVA as well 20:27
pugs_svnbot r20753 | diakopter++ | [yap6] fixed semicolon-less trailing statements in statement lists (including inside blocks)
Auzon I'm personally working on the Perl 6 test suite. The only skills needed for that are Perl 6, the ability to read the specs, and some general testing knowledge. 20:29
diakopter pugpuppy: probably you should read the Synopses... the specification for the Perl 6 language: perlcabal.org/syn/
lambdabot Title: Official Perl 6 Documentation
[particle] pugpuppy: yikes, that's an old link 20:30
parrot's assemble.pl went away long ago
pugpuppy can you get me the new/ fresh link 20:31

Auzon There was a NQP (or was it PIR?) tutorial a while back that could help with hacking on Rakudo. The barrier to entry there is a bit higher than things in the Pugs repository, however
pugpuppy okay, I had a look at the second one. Its two am out here and I will catch up with you tomorrow 20:37
thanks a lot for your help
Auzon See you.
[particle] welcome!

diakopter pmurias: the syntax errors are pre-source filter I think :D 21:09
the source filter actually doesn't do that much
Auzon What Perl are you using, diakopter? 21:10
diakopter just takes the rule name and makes the rule rulename {}; block a my $rulename = parser {}; declaration
strawberry 5.10.0.latest on win32 daytime and 5.10.0 on x86 darwin at nighttime 21:11
but I think p6eval uses 5.8...?
Auzon Right.

Auzon or, it's $?PERLVER
OK, just wondering if Perl 5.10 had issues with yap6 that 5.8.8 didn't
diakopter *wow* I haven't implemented the memoization correctly... it could be even faster. 21:17
21:18 jhorwitz left
diakopter hm; yap6 is hitting p6eval's memory limit on 21 nested expressions 21:19
surely there aren't that many in STD.pm ;)
Auzon So 21 brackets deep? 21:20
diakopter yeah 21:21
