for concatenate with no intervening whitespace allowed 13:02

and I'm adding two more now
postfix autoincrement will signify mandatory trailing whitespace 13:03
and postfix autodecrement will signify optional trailing whitespace

diakopter to make constructs like this prettier: token1 + o(o(p6ws) + token2) becomes token1 + o(~token2) and o(token2 + p6ws) + token1 becomes o(token2++) + token1 etc 13:07
hopefully the rule p6ws won't ever have to be directly referenced 13:08
also I'll overload ! to be the negative lookahead
you don't need positive lookahead (obviously) in RD parsers 13:09
since that's all it ever does....
pmurias: ok? 13:10
I'm trying to optimize this syntax not just for readability of the STD_hand grammar, but also the future readability of the grammars generated (from both STD.pm and from inline operation mutation/creation and grammar declaration/application) 13:12
pmurias diakopter: seems ok
shouldn't | mean perl6 longest token alteration? 13:13
diakopter now I just finished converting all the parser generators over to CPS, so that they can modify both the input stream and the continuation parser/handler itself
pmurias: it does! now :) which I haven't checked in 13:14
I added longest-token-matching (by default) to alternate()
that will obviously slow it down LOTS
I added that a few hours ago 13:15
I guess & could mean first match
since it's at the same Perl 5 operator precedence level 13:16
moritz_ & has a meaning of its own in p6 regexes
diakopter right, but this isn't even the translation stage, yet
I'm not trying to replicate the Perl 6 syntax in Perl 5
just make it easier to express RD grammars in Perl 5 13:17
in the translation stage, we'll use STD_hand to read STD.pm, and then generate a Perl6in5::Grammar from it, called STD_auto.pm 13:18
similar to what TimToady is doing in gimme5
13:19 p6eval left, p6eval joined
diakopter I'm attending YAPC::NA again this year, and I want to have STD_hand done (so that it can at least generate an AST from STD.pm) by then... so maybe people there will take an interest and pitch in to implement the marriage with elf/smop/whatever 13:21
can pugs implement grammar-switching/mutation in BEGIN {}? 13:22
I know it does inline operators 13:23
pmurias don't think so
pugs grammar is coded in haskell
diakopter can any of the other implementations do that yet? 13:24
moritz_ no
diakopter then one of my goals is for yap6 to be the first to prove that concept
moritz_ kp6 does BEGIN blocks, but they don't modify the grammar
btw what's the syntax for grammar switching? 13:25
I think pugs has limited support for macros, though
diakopter I don't think there will be a Perl6in5::Grammar syntax for grammar switching; it'll built into some special parser constructor/handler. if a "use GrammarX" (I think that's the Perl 6 syntax???) statement is encountered, special parse-time handling will occur to interpret/evaluate (using the grammar-translation continuation handlers) that particular branch of the AST (and probably everything up to it, which is why it's good for ... 13:30
... such things to be in a BEGIN block) to generate the new/modified grammar, and use that instead of the continuation parser that was passed to the "use GrammarX" parser. Macros would work the same way. Same with quoting (including balanced stop character detection).
where "that particular branch of the AST" is the previously declared grammar GrammarX {} or whatever 13:31

diakopter bacek: would you message p6eval directly while a conversation is occuring please?
esp if you're using perl6: 13:33
moritz_ diakopter: I was refering to the Perl 6 syntax for grammar switching - and I think you're right that it's somehow done through 'use'
diakopter and since 'use' statements need (still) to be applied at parse-time anyway (as in Perl 5) in their own compilation unit (just like BEGIN), that same "use" handler would be "use"d. 13:35
and as TimToady said previously, "use" statements fall into the category of things that halt the longest-token-matcher and commit to a branch immediately 13:37
at least, if my understanding of what he said is correct.

yath forgot to report a bug early enough to get it into etchandahalf :-(
so i'll have to recompile kernels every time now 13:44
*sigh*
diakopter I really need to deprecate/fix this stupid gt0() function I created... it's rather broken
moritz_ yath: not so bad. If you run stable, you don't need to recompile your kernel very often 13:45
yath: and most of the time it's simply a matter of running make-kpkg
yath moritz_: in the last four weeks there were about five or six DSAs just dealing with kernel stuff :(
moritz_ yath: I know, but most didn't affect desktop machines 13:46
yath moritz_: it's not that compiling a kernel on POWER6 takes long, but it's just an extra step instead of apt-get update && apt-get upgrade
moritz_ yath: ok, I agree with that. So use Lenny instead ;-)
diakopter I kindof want to kill pugs_svnbot and replace with dalek, since dalek has decent flood prevention, so my longer commit messages work :) 13:47
yath moritz_: not until it's stable :P problem is, in our corporate network i have no direct internet access, so i have to have to get the new packages from security.d.o all the time, run dpkg-scanpackages and so forth
moritz_ yath: ok, $work is a good reason :/
yath fortunately i have limited access to a DMZ. so i wrote a perl-ten-liner that merges the output of ls /mirror with Packages.gz and builds a zip with the new packages ;) 13:48
moritz_ hey, we need #os_perl where perl people can discuss and rant about various OS ;)
yath .o(emacs--)

diakopter pmurias: OOPS I got my operators wrong when telling them to you earlier.... SLAP forehead. "." enforces no whitespace, "+" enforces whitespace, "-" allows optional whitespace
that way, ++ and -- are consistent as the trailing ones 13:50
13:52 jan_ left
diakopter I guess ~ will be the optional leading whitespace, and ^ for mandatory leading whitespace (even though that meaning is nearly opposite its other meanings; oh well) 13:52
oh wait, no, can't be ^ 13:53
diakopter looks for a unary prefix that's so far unused
I wonder if there's any way to overload unary + and - ....? 13:54

14:12 jhorwitz joined
diakopter the biggest benefit of these infix concatenate variants is that they always expect two and only two argument parsers. This makes a lot of the recursion in the parser generators unnecessary; the recursion is handled by Perl 5's operator precedence levels. 14:16

moritz_ or would you rather prefer to work quietly until you have something to show?
s/something/something more/
pmichaud the last four lines of S29-list/join.t look odd to me. At any rate I think the last two tests are incorrect. 17:58
moritz_ is totally confused about what is allowed and what isn't 17:59
pmichaud I don't think there's a .join method on Str invocants.
diakopter moritz_: you might as well mention it as an experiment in recursive descent grammars towards mutable grammars for Perl 6 18:01
moritz_ pmichaud: our Str multi method join ( $separator: @values ) 18:02
pmichaud: from S29
pmichaud moritz_ isn't that in the section on List methods?
moritz_ pmichaud: does it matter? 18:03
$seperator: is a scalar, and marked as invocant
pmichaud I think that's actually incorrect in S29 -- I think it should be our Str multi method join ( @values : $separator )
otherwise @values.join(';') doesn't work
(in r20722 I even changed S29 to read that way.) 18:04
diakopter hey moritz_: can anonymous subs be lvalue subs?
moritz_ diakopter: dunno, you have to try it ;) 18:05
diakopter ok
moritz_ it burns down to "can anonymouns subs have :attributes?"
s/burns/boils/ ;-)
18:08 Jedai joined
diakopter I'm hoping that the lvalue-ness checking of postfix in/decrement is all that remains after overloading... I don't want my overloaded ++ &routine's result to be assigned back to the object of the ++. 18:10
pmichaud okay, I retract my earlier statement. The tests are correct as written. 18:11
(method fallback causes it to work.)
thus "foo".join(@values) falls back to join("foo", @values) 18:12
18:13 dominiko left
pmichaud but the test descriptions are wrong then, as 'foo'.join(':') is equivalent to join('foo', ':') and not join(':', 'foo') 18:16
and, come to think of it, so is the output. hrm.
I'll add a note to S29-list/join.t and maybe Auzon can clear it up :-) 18:17
moritz_ well, if you're sure the test is wrong I can clean it up now
pmichaud I'm not completely sure of anything except that what is in the test file didn't match S29 (either before my change or after)

19:29 eternaleye left
Auzon I never really used that part of P5. 19:29
pmichaud I wonder if I can get interpolation to work in rakudo. :-) 19:30
er, closure interpolation. the hooks are there already --just need to fill them in.
moritz_ pmichaud: why not? seems like "a jonathan" to me ;) 19:31
pmichaud heh.
okay, I'll do it then! Why should jonathan++ have all the fun? ;-)
Auzon I imagine elf could understand them without too much work either...
moritz_ (I hope you don't mind me paraphrasing you out of context ;)
pmichaud not at all :-)
I paraphrase Larry all the time (hope he doesn't mind it :-) 19:32
moritz_ Auzon: probably, but I think mncharity and pmurias will wait for TimToady++'s refactor of the quoting stuff
in STD.pm, that is 19:33
Auzon Makes sense. Rakudo doesn't use STD.pm, does it?
moritz_ no, but its parser is modeled after STD
pmichaud I'm aiming for STD.pm. I'm hoping/expecting that we'll be using STD.pm by the end of summer. 19:35
I think I should have protoregexes working by mid-to-late June. That'll take care of the biggest part of it. 19:36
longest token matching sometime in july or august
Auzon moritz_: Did you look at my test cases for samebase? 19:37
moritz_ Auzon: no. Will do now. 19:38
Auzon The spec is a bit rough there, so I made some assumptions based off of samecase 19:39
moritz_ uhm, where did you get all these fancy unicode chars from?
;) 19:40
btw it might be helpful to add a smartlink that points to S05 as well
Auzon KDE's character map :)
I just searched for "with stroke" and got several that matched 19:41
moritz_ uhm wait
is there a "combining stroke" char?
Auzon I don't understand unicode that much so the can probably be improved.
moritz_ problem is, combining chars can be placed onto any base char 19:42
Auzon yes, there is. U+0335 and U+0336
moritz_ which means that F + stroke can just be written as "F\x{0335}2C"
s/2C// 19:43
Auzon So I need to find something without a combining character, correct?
moritz_ no
it's just a case that doesn't occur in unicode world 19:44
Auzon Oh. OK, then I can change the test
moritz_ tries to get his head straight
actually I don't know if it's worth the effort for you to read about unicode stuff 19:45
maybe I should take over that test, and consult with Juerd where I'm unclear
Juerd Ｕｎｉｃｏｄｅ ｒｏｃｋｓ ：）
moritz_ Juerd: it does, indeed. But it't hard to write tests for if you don't grok it 19:46
(which I think we can't expect from Auzon++)
Juerd It's also hard to write tests for if you do :) 19:47
moritz_ indeed
Juerd Encodings are pretty easy, but Unicode is hard.
Auzon I just haven't dealt with it so far (except in the sense of making it store and display correctly in my webapps)
Juerd Auzon: That's what I meant :) 19:48
moritz_ heh ;)
actually the spec is unclear here
at least for "samecase" 19:49
there are two versions of the :samecase regex modifiers
one "dump" which copies on a per-grapheme base
and one "smart" which tries to detect a pattern (uc, lc, ucfirst, lcfirst, capitalize) and applies that pattern to the second string 19:50
S29 is silent about which the function/method samebase() refers to
moritz_ composes mail to list
pmichaud moritz/auzon: Does sending questions about spec interpretation seem to work best for you? 19:51
(er, sending questions "to the list") 19:52
Auzon samebase and samecase are relatively new to the spec.
moritz_ pmichaud: so far not very well
pmichaud takes too long to get answers?
moritz_ one isn't clarified at all
the one about inconsitencies with private method syntax in roles and classes
Auzon pmichaud: I've primarily been asking in here, which has been sufficient so far for me.

Auzon: it's just to keep the community informed that you're still doing things ;)
mncharity pmurias: re Cursor5, it does look interesting, and modulo checking with TimToady, I encourage folks to work on it. It could be neat to run it against a test suite, to get some idea of coverage and performance. Absent that, it's unclear whether it could be an alternative to yare.
Auzon moritz_: I'm writing up an end of week report now. I had something keeping me busy all of Friday and half of yesterday
moritz_ Auzon: ok, thats fine
mncharity re Cursor5, actually, p6 versions might be more interesting than the p5 versions - could run it on non-p5 backends. 20:28

pmurias what should i run?, i'm using my sluggish desktop machine now 20:36
Auzon I added it to TASKS and I can send an email if that'd help
mncharity pmurias: re 'replacing the architecture of elf will need to be done sometime', <pause>
moritz_ Auzon: don't wast your time on the email. If it's in the spec as a TODO, it's known and will eventually be worked on.
Auzon ok 20:37
pmichaud istr that pack/unpack got some discussion on p6l in the not-too-distant past.
mncharity re run, cd misc/pX/Common/yet_another_regex_engine/; prove t/re_tests.t . it will probably require you to update your Regexp::Common from cpan.
pmichaud might check the archives.
moritz_ pmichaud: I think they discussed how objects can be serialized, or how they can serialize themselves or some freaky stuff 20:39
mncharity re 'replacing the architecture of elf will need to be done sometime', the elf architecture undergoes continuous replacement. :) Next steps are likely 'move IR analysis out of Emit' and... hmm, that may reduce the importance of moving to multimethods internally... so, not clear what after that.
pmurias re replacing architecture doing BEGIN correctly requires compiling the whole program piecemeal, and then serialising it to disc 20:40
mncharity why?
pmurias sub foo {...};BEGIN {foo()}; 20:41
my $var;BEGIN {$var = 123};
my $var;BEGIN {$var = 123};say $var;
mncharity why would that require any change in how the disk is touched?
pmurias s/to disc// 20:42
Auzon Will Perl 6 emulate sprintf like Perl 5 did?
pmurias i should double check what i write
it easier to implement some thing when you just creat stuff at runtime and the serialise it 20:44
mncharity my impression is BEGIN requires running things at compiletime (as do macros) - not hard, and observing side effects - hard. Containers might help, plus other observers... BEGIN{eval('our $*foo;')}... it might be easiest to have an emitter variant which logs changes as they go by. 20:46
pmurias that's the way kp6 did it 20:47
it ended up rather messy
mncharity variant, or containers?
Auzon away&
mncharity Auzon: chao
pmurias mncharity: special containers 20:48
and some magic in the emitter, if i rememer correctly
but i would go with the serilize everything aproach 20:49
mncharity: the error stayed
in re_test.t
* re_tests.t
mncharity ok. so... I have no idea what mix static analysis, emitter additions, and compile-runtime magic will be needed for BEGIN. basically, if we can't do ruby-like eval-based metaprogramming in BEGIN's, we have a problem. todo list. ;) 20:50
yath yay, just reading through S02: Heredocs allow optional whitespace both before and after terminating delimiter. Leading whitespace equivalent to the indentation of the delimiter will be removed from all preceding lines 20:51
i wanted this for AGES
mncharity re 'the error stayed', bizarre. it's been tested now on a variety of platforms.
yath \o/
mncharity :)
pmurias: what version of Regexp::Common are you using? 20:52
pmurias 2.122 20:53
mncharity re serializing the universe... eep, there has to be a better way.
pmurias it's simple 20:55
mncharity re 2.122 :( sigh. oh well. then issue still not understood. but established not to occur on a variety of linux distributions, MacOS, and assorted hardware. :/
pmichaud re: 20:40 <pmurias> my $var;BEGIN {$var = 123};say $var;
S04 still says: Some closures produce Code objects at compile time that cannot be cloned, because they're not attached to any runtime code that can actually clone them. BEGIN, CHECK, INIT, and END blocks fall into this category. Therefore you can't reliably refer to run-time variables from these closures even if they appear to be in the scope. (The compile-time closure may, in fact, see some kind of permanent copy of the variable for some storage clas
pmurias pmichaud: it's possible to do it with some trick or other in order for use to work 20:56
mncharity s/(if we can't do ruby-like eval-based metaprogramming) in BEGIN's/$1/ ;) yay, macros. 20:57
pmurias mncharity: why are you against serializing the universe ?
mncharity because I don't understand what it means 20:59
bbiab
how can END do cleanup if if can't access runtime variables? what purpose does it then serve? 21:03
unless subs aren't considered variables? anyway & 21:04
pmichaud they can access runtime variables, just not lexical ones. :-)
i.e., package variables and file-scoped lexicals are okay.
21:04 perl7 joined
mncharity ah, ok. sounds like an S04 'insert "lexical"' edit request, unless I just missed it, or the paragraph's context makes it clear. 21:05
pmurias dosn't it only refer to cloned closures? 21:06
mncharity unless "runtime" variable is an alias for "lexical" variable?
pmichaud I'm not sure that it's referring only to lexical variables. 21:07
and yes, that may be only for cloned closures.
pmurias cloning TimToady would help ;) 21:11

spinclad diakopter: re leading whitespace operators: why not prefix ++ and -- ? "(++spaced+out++)" 23:07
23:13 jisom joined
diakopter spinclad: I took a look at that; I couldn't get the overload handler to distinguish between them... also, I couldn't use the real postfix ++/-- either 23:20
so I ended up using a source filter :) 23:21
