perlDreamer TimToady, so no 4 arg substr in Perl6? Replacement is just through lvalue assignment? Please forgive me for belaboring the subject, but your answer wasn't clear as to whether the omission is due to it not being in the language or not. 04:29
and in the pugs test suite, all 4 arg substr's are commented out. 04:31

rindolf Alias_: here? 11:31
Hi all.
Alias_ yo
masak 'ello
rindolf Hi Alias_ 11:33
Alias_: I tried to commit something into svn.ali.as/ using my CPAN id and could not.
Alias_ yeah, sorry about that
I'm working on it
rindolf Alias_: is there anything I can do to help? 11:34
Alias_ Not really, it's mostly down to me finishing the repository manager
rindolf Alias_: I see.
Alias_ Actually, I can probably run/release the current version, and add you manually 11:35
masak Alias_: PPI is great, btw 11:43
Alias_ Thanks :)
masak you're welcome. I noticed because I'm currently looking for something similar for p6 11:44
Alias_ runs
masak no, I didn't mean it that way
I'm looking for existing ways to get a syntax tree
Alias_ hrm... I'm not entirely convinced it's going to be possible
masak from perl 6 source
so far I've found PIL1, which does not seem to be what I want 11:45
Alias_ It was SUPPOSED to be possible... but I'm not entirely sure it will be possible
masak Alias_: not possible? then what is it that the parser produces?
Alias_ code
masak hm 11:46
masak wants a non-ASCII representation of the source file
Aankhen`` Will Shift-JIS do? 11:47
Alias_ :)
masak checks
Alias_ no, you want a deserialized representation 11:48
You want a Perl 6 DOM
masak yes!
is that too much to ask?
Aankhen`` That would be nice indeed.
Alias_ I have an ugly suspicion it's going to be even more impossible than in Perl 5
masak it seems perfectly natural to me
11:48 pnu left
masak Alias_: what's the difference between p5 PPI and p6 DOM? 11:49
and why would the latter be even more impossible?
Alias_ Well, for one, the p6 DOM is still a moving target
11:50 Aankhen`` left
masak Aankhen``: I don't see Shift-JIS among the valid pugs backends 11:50
Alias_: well, disregarding that
Alias_ The P6 syntax is also a good deal more complicated than P5
Which doesn't make it impossible I guess, just harder
11:51 pnu joined
Alias_ PPI implements a relatively static grammar 11:52
You pretty much need static grammars to make a DOM work :)
masak Alias_: hm. good point. let's say, though, that I'm interested in parsing vanilla p6 11:53
Alias_ TBH, dunno
I'm sure you could implement something like PPI
But you'd probably have similar issues as with PPI, you couldn't use regexes really 11:54
You'd have to cheat rapaciously
masak I was thinking of cheating to the extent of not implementing p6PPI at all :) 11:55
my goal is to do a bit of analysis on the pugs test suite
and it would help greatly if I could traverse DOMs, not text files
Alias_ Well, I don't believe there's a DOM parser for Perl 6 11:56
wolverian just use the grammar.. (;
masak wolverian: please elaborate
is that feasible today?
11:56 DarkWolf84 joined
Alias_ wolverian: Don't start, we don't want to lead him down a false path 11:56
he's kidding
masak Alias_: thought so
wolverian masak, no, we're not bootstrapped yet. there _is_ the grammar, but no engine to run it, I think.
Alias_, sorry. :)
Alias_ Can the grammar parse without executing? 11:57
masak Alias_: name one place where it can't
except non-vanilla p6 11:58
wolverian changing the grammar at runtime
Alias_ loading modules
masak hm
Alias_ Compile-time code
masak Alias_: yes, there is that. the test suite has some of that
wolverian as long as it doesn't change the grammar, it should be fine, I think
Alias_ wolverian: Well, arbitrary code == exploit == not allowed 11:59
masak so, how would you do it, today, given today's tools?
Alias_ BEGIN { while (1) { $_++ } }
wolverian Alias_, I mean parsing without running should result in the same dom, as long as the code that would have been run doesn't change the grammar
Alias_ or any equivalent you can come up with
12:00 rindolf left
wolverian s,doesn't,wouldn't have, # I don't even know anymore 12:00
12:01 crashmatrix joined
masak given that I went for a simple text-matching approach, looking for sub calls, I would still have to recognize strings and comments 12:02
it gets complicated quickly
I'd like to have something do the hard lifting
Alias_ Yes 12:03
Yes it gets VERY complicated quickly
masak Alias_: yes, you would know
Alias_ indeed
masak and I guess you wouldn't recommend that road
12:03 aindilis joined
Alias_ Well, I was told it could be done internally 12:03
masak that's what I'm hoping for 12:04
Alias_ That somehow the parser would have a mode that would prohibit grammar modifications, and thus give you a parsetree
masak sounds great
wolverian .. like mad does for perl5? hm. not sure if it's compile-only
just a thought, I haven't worked with mad 12:05
Alias_ uuumm... possiblyu
I haven't worked with mad
wolverian heh
anyway, we're interested in 6 now :)
masak didn't know mad was available
wolverian masak, did you look at pugs -C? 12:06
masak wolverian: yes
found PIL1, was half disappointed, half confused 12:07
is there anything else in -C I should be looking at?
bloonix $fh.say "hello world" returns an error, why? 12:10
masak bloonix: should you perhaps write $fh.say: "hello world" ? 12:11
bloonix masak: yes, I should :) thx! 12:13
masak np
that still bites me too sometimes
bloonix I searched for an example but didnt find one
masak it's still too early to blame people for not having p6 syntax down pat :) 12:14
bloonix hmmm I tries flock on the filehandle but I doesnt work
:set nonu
wolverian masak, not sure what's bitrot and what's not 12:15
(if any)
pasteling "bloonix" at pasted "use perl5:Fcntl <flock>; my $f" (10 lines, 245B) at sial.org/pbot/26601

wolverian masak, I meant -C
masak wolverian: oh 12:17
bloonix any suggestions?
masak bloonix: not at present 12:18
was it the flock call that broke things?
wolverian: I wish I could attribute what I saw to bitrot
PIL1 just doesn't seem to be what I need
way too chewed already
wolverian heh, try -CPugs 12:20
masak ok
wolverian no, don't :)
masak ok :) 12:21
I did, anyway. it said "pugs: XXX"
terse, but not correct, unfortunately 12:22
wolverian it's more verbose on feather..
masak I don't have access to feather 12:23
wolverian oh! well, ask Juerd
masak wolverian: yes I know. I just haven't found a compelling reason to get an account. to check the verbose output of pugs -CPugs seems like somewhat less than a compelling reason... 12:24
usually I make do with my own computer, and don't need a feather account
bloonix: seems to me flock is not imported properly 12:25
I wish I had a fix for you, but I don't, sadly :(
bloonix where is the different between sub FOO () {} and constant $FOO ? 12:34
masak well, the syntactic difference is obvious: $FOO contains a dollar sign 12:35
so, I suppose that's not what you mean
I guess they can be used in much the same way if &FOO (the sub) always returns the same value 12:36
but using a sub where a constant is enough seems a bit wasteful
fglock masak: you can probably write a Match-to-DOM converter based on v6.pm 12:37

ruoso you can look at the Pugs::Runtime::Match 12:40

you just need to create a DOM tree based on the matches
masak ruoso: thx

masak 's hopes rise
fglock masak: lib/Pugs/Compiler/Perl6.pm is the place to look for how to get from source code to the match object 12:43

it would be desirable, I think, for the expression to further specify its parts 13:10
an expression parse tree, more or less 13:11
...but reliable division into statements is already a great help on the way :)
