TimToady crum, I just figured out that list associative operators need to be right associative when the operator differs, not left 04:39
araujo Tene_, hah .. oh, well, it is not a big thing really ... it is a stack-based object oriented language , it's how i like to define it
TimToady by 'stack-based' do you mean closer to Forth or to Java? 04:40
araujo And .. I am trying to beat perl 6 in the operator and keyword count
:-P
TimToady I mean, Perl 5 is stack based...
araujo TimToady, Closer to Forth 04:41
Like a concatenative language
TimToady so kinda like a Parrot that is stack-based rather than register based
araujo Everything is an object and even a stack is an object, where the stack is the main execution environment ... 04:42
Correct TimToady
TimToady so why not just program it in Japanese? :)
araujo hahaha I need to learn japanese first 04:43
:-]
I have found the message passing style and the stack based approach very appealing ..
And .. they happen to work very well, either syntactically , and semantically
together , that is it 04:44
araujo is even thinking to get it run by parrot 04:48

ruoso @tell pmurias in the case we really want to make the code more spec-aware, we could make $obj.prefix:<=>() explicitly, instead of doing =$obj 12:00
lambdabot Consider it noted.
ruoso since prefix:<=> is expected to be a method on Iterator 12:01
and, I think, the default implementation is: multi prefix:<=>(Any $obj) { $obj.prefix:<=>() } 12:02
and that is probably the default for every unary operator
and that's why TimToady told us the compiler is free to optimize it away where there are no multi candidates for the operator 12:03
that means I don't think it is that bad for mildew to simply drop the support for unary ops overload before compiler bootstrap 12:04
since you can simply override the method in the object, instead 12:05
@tell pmurias I started writing in a @tell, but then wrote some stuff directly... please backlog (which you probably already did) 12:06
lambdabot Consider it noted.

ruoso @tell pmurias btw, the use of postfix:<++> as a method is an error, I just haven't the time fix it 12:08

lambdabot pmurias: You have 3 new messages. '/msg lambdabot @messages' to read them.
ruoso pmurias, I think the idea of having it as a multi is allowing to change the default behavior 13:08
which is to delegate to the object
pmurias i guess we can always change it later if it proves to be incorrect 13:09
int.infix:<< >= >> in array_iterator seems to be incorrecy 13:11

ruoso pmurias, it is also incorrect
pmurias is there a reason for S1P__Array__Iterator to be in c/m0ld rather that p6?

slavik does rakudo have something equivalent to haskell's [3,5,7,...] ?

Haskell is slightly magical.
slavik pmurias: haskell is smart with lists like that :)
pmurias ghc thinks otherwise 13:19
slavik maybe it was 2 dots?
either way, I remember that it could generate a list given a few starting elements

masak TimToady: sometimes I'm unhappy about how restrictive the 'class Foo;' syntax is. the idea is very sound, to remove a level of indentation that encompasses practically the whole file. but I can't do 'class Foo is Bar;', because there's no way to put a use statement before that statement. putting the 'is Bar;' statement on its own line (after the use statement) feels inelegant in another way. the class-semicolon syntax is both full of 13:47
promise and a straitjacket right now.

diakopter pmurias: or, is the test that these .o files built correctly in build-tests/ ? 15:25
pmurias you should have executables in build-tests 15:26
they end with .t
diakopter ahah... yeah, the .t files should be .t.exe on windows
18 .t files, yes. 15:27
should I just try executing them? :)
pmurias you can type make test to run them
diakopter oohhhhhhhhhh
ok
diakopter feels dumb[er]
well, if valgrind were installed 15:28
pmurias you can comment valgrind out
TimToady frew: if the calculated length of a substr is negative, it should probably fail, since it's more likely to be a logic error than to indicate a desire for a reversed string 15:29
pmurias: yes, &Foo::Bar::infix:<+> is quite valid 15:30
pmurias diakopter: valgrind doesn't seem to be ported to windows but it's only a debugging tool
diakopter: if the tests run you can try running mildew 15:31
diakopter: type "make test" in v6/mildew to run mildew tests
frew alright 15:32
I'm gonna see about adding some tests to assure it fails in that case 15:33
TimToady masak: yes, STD allows use before class Foo is Bar; 15:34
however it's not clear the p6 autorecognizer will work in that case
diakopter pmurias: well, the .t files need renamed to .t.exe, and the smop.dll needs copied to the build-tests dir, but they run
TimToady so you might have to start with 'use v6'
diakopter pmurias: but prove doesn't want to run them with the .t.exe
TimToady alternately, class Foo is Bar; might autouse Bar 15:35

moritz_ frew: I usually don't, since pugs isn't developed at the moment

moritz_ when you are in rakudo's working dir, you can say 'make t/spec/S29-str/uc.t' 20:23
frew ok 20:24
alright, and you guys apparently already did this for all of the ones I checked in
moritz_ I did, yes ;) 20:25
frew haha, ok
I have a simple syntax question
20:25 schmalbe left
moritz_ shoot! 20:25
frew it wouldn't make sense for my test to ensure that my StrLen $f = -1 fails right? Because that's a function of the StrLen instantiation
right?
moritz_ -1 is an integer 20:26
frew is that a problem?
moritz_ so it would make sense to test that somewhere, I think 20:27
frew yeah
but I am working on strsub right now
moritz_ well, I don't think that StrLen inherits from Int
20:27 shinobi-cl left
moritz_ what is strsub? 20:27
frew woops
substr
sorry
so should it look like this: my StrLen $f = new StrLen(-1) or something? 20:28
as it stands I don't think StrLen exists at all, but I want to add the tests with it in substr 20:29
moritz_ "new StrLen(-1)" certainly does not work, maybe StrLen.new(-1)
or StrLen.new(codes => -1)
20:29 jferrero joined
moritz_ but in either case positive values make much more sense ;-) 20:30

moritz_ the only way I know of to generate StrLen objects are Str.index, Str.rindex and maybe items of the match object 20:37

mncharity which means taking the STD_blue (aka gimme5/STD.pm) ast for the STD.pm source file, and trying to get misc/elfish/elfparse to generate valid IR and p5 for it. 21:42
moritz_: thanks. 21:43
pmurias the README talks about things like elfgreen and elfgreenstd which don't seem to be in elfparse 21:44
mncharity make elfgreen; make elfgreenstd or make all
pmurias mncharity: do you think you'll get better parser performance then STD.pmc? 21:50
mncharity yes, 21:52
21:56 |jedai| left 21:57 |jedai| joined
mncharity The near-term objective is to emit something more like STD_red than like STD.pmc. STD_red works "well enough", and is obviously fast. The challenge will be fudging the parts of STD.pm which assume there's a cursor, into something rx_on_re compatible.] 21:57
Specifically, rx call cost is comparable (within a few x) of method call cost, and object allocation is minimized. 21:59
The p5 code currently emitted is all regex all the time. "token"ness is ignored. todo. 22:00
moritz_ isn't "token"ness as simple as putting (?>...) around the emitted regex? 22:02
mncharity yes
moritz_ or is that around each atom of the token? 22:03
mncharity though one can do more efficient things, and that's the goal. ie, no backtracking machinery overhead needed.
re 'or is that around each atom of the token?', don't recall, sorry. 22:04
atom seems more likely.
pmurias it's a (?>...) around every construct that could backtrack 22:07
mncharity pmurias: Basically, having parsing performance comparable to STD_red is required. Otherwise elf performance becomes unacceptable. So, whatever it takes. But the main theme is kludge around LTM, and get all the token atom sequencing down to method call cost.
ah, that makes sense. 22:08
mncharity tries to remember what /a ** b/ and /a ~ b/ are... 22:09
moritz_ a ** 2 is a repeated 2 times 22:10
and /a ~ b c/ is goal-matching
and similar to /a c [ b || <panic: "can't find terminator"> ] / 22:11
mncharity STD.pm is using the a ** <b> and a ** 'b' interleave forms of **. ~ looks more fun. 22:14
22:14 ejs left
moritz_ ah, a ** 'b' is /a [ b a]*/, iirc 22:15
a's separated by b's
mncharity yeah. the rewrite on ~ ... "something more like: $<OPEN> = '(' <SETGOAL: ')'> <expression> [ $GOAL || <FAILGOAL> ] ", but that's obviously an approximation (ie, there's actually no $<OPEN> set, yes?). so... sigh. I'll fudge an expansion rule to match observed gimme5 behavior on STD.pm cases. puttering onward... 22:17
be nice to have the spec nailed down at some point. 22:18
moritz_ I guess that SETGOAL sets $GOAL 22:19
pmichaud wanted to commit a clarification of that things, iirc
but he seems to be very much absorbed with organizing infrastructure for Rakudo sees days

mncharity hmm, re spec nailing down, I hypothesize we need a concept of a version of p6 other than p6.0 or release candidates. Ie, to formalize the notion that we're not [it seems unlikely or suboptimal] monotonically converging on a p6.0, but rather getting to a "version like p6.0, but explicitly not it, and intended to get experience using p6 prior to settling on the p6.0 spec". 22:29
perhaps
ie, "p6 exploration builds", where @larry still feel free to modify the p6 spec, in light of people starting to get experience actually using draft p6. once we hit 6.000, a whole lot of flexibility goes away. hmm, unless we declare 6.000-6.whatever to explicitly be unstable development versions. 22:32
anyway, back to hacking...

mncharity re 6.0.0, it might be useful to declare 6.0.N to be "early adopter's release"s, giving the flexibility to only freeze the spec when "it feels the right time". 22:44
or even do an incremental freeze.
mtnviewmark wouldn't it be more perl6 like to use an adverb? :-) 6.0:pre(1)

mncharity TimToady: ~ is speced as taking 2 right side arguments, but /a ~ b c d/ is currently grabbing the d, parsing as ~(a,termish(b,c,d)). /[a ~ b c] d/ works. perhaps groupify the one or two cases in STD.pm where there's a d? 23:08

shinobi-cl im trying to use the read method on a file... readline works, and both are listed together on S16... 23:15
moritz_ seems not yet implemented in Rakudo
care to submit a [TODO] bug report?

sure, where i do that?

rakudo says "1" and I tend to agree with it. 23:19
