kid51 Does anyone know julianalbo's #parrot nick? 02:46
We have perlcritic failures in a file he contributed today: examples/nci/xlibtest.pl
paco kid51: he is NotFound 02:47

chromatic kid51, that file isn't Perl 5; it's NQP. 02:56
kid51 Yes, I noticed that. And since I haven't played with NQP, I decided not to try to fix the problems myself, lest I make it worse. 02:57
chromatic The tabs we can fix, but strict and warnings....

Time sure flies when you're reading perl.qa ;-)
PerlJam anyone know how to just test PGE? 03:34
like if I make a change to PGE how do I test that a) I didn't break anything and b) that my change does what I think it should 03:37
chromatic I usually test Pheme and Rakudo. 03:41
PerlJam Hmm. lots of machinery betwixt me and PGE at that level. 03:42
chromatic Sadly yes. 03:43
I'm sure PGE could use more comprehensive tests. 03:44

diff: www.parrotvm.org/svn/parrot/revision?rev=30806
s1n chromatic: what was wrong with key_string? 04:14
chromatic There's a potential infinite loop between it and get_string in the Key PMC. 04:20
I'm trying to get rid of it by making sure that everything outside of Key and Key-like PMCs calls get_string on the PMC rather than key_string directly.
s1n iirc one of the backtraces of those 64bit crashes always seemed to originate around key_string calls 04:29
i'll test some stuff tomorrow with my nightly, maybe that cleared it up 04:30

NotFound I'm worried about core_type_id. Maybe the type of self is the one to ne mapped. 09:27
09:29 rurban joined
NotFound An interesting question comes to me: are the HLL common to all running interpreters? Or I can, for example, have an stable perl6 in the main interpreter and load a testing version in a child interpreter? 09:30
rurban I've started now with java as language/jvm. Is then name okay? I copied from dotnet and want a class2pbc.pbc. But maybe we want to parse java sources also. Then this could go another language, like language/java. Or should this be combined into a bytecode converter and a java parser within the same language? 09:31
NotFound rurban: I don't think that the parser must be bound to the jvm. The parser can be used to generate parrot code. 09:33
09:33 barney joined
rurban Sure. It's almost bidi - as particle named it yesterday. parse the bytecode and parse the source. 09:34
NotFound An by the way, there are already java compilers targetting jvm, no urgency to write another ;) 09:35
rurban It's just that I build all the exception classes and other helpers which should be used by the source parser and by the bytecode converter
I want to target parrot of course.
Tene rurban: languages/jvm is a good name
rurban The main reason is that perl6 can use java classes then. swing and such. 09:36
php, pynie and ruby also of course
NotFound rurban: and maybe use jdbc drivers
rurban There's a huge common lisp converter (java => cl) around, which I saw at the last conference. I'll check it out. 09:37
With this step I've moved languages/dotnet/build/SRM to compilers/SRM 09:38
(Stack to Register Mapping)
Maybe some other languages want such perl5 classes also. But it's only useful for bytecode with stack vm's. 09:39
NotFound Soemone is working on a csharp compiler?
Tene Not that I've seen. 09:40
NotFound Just curious.
rurban Jonathan via C#=> dotnet dll => PIR
Different to Jonathan I want to generate most of the opcode table, the translation rules, automatically. 09:42
jonathan Best just to do .Net => PBC 09:43
Because then C#, VB.NET and other things will "just work" 09:44

09:52 bacek joined
rurban jonathan: How about your opinion of moving SRM to compilers? It's used in dotnet, WMLScript and maybe jvm 09:54
jonathan rurban: I purposefully kept that stuff factored out, with the view that it could be useful elsewhere or that we could implement better algorithms and test them. 09:56
rurban Ok. 09:57
jonathan So yes, if multiple langauges can use it, it's perhaps a good idea.
I think have at least a couple using it first, though.
Just to show that it can work.
rurban The next problem is that such compilers will not get installed. I hope the translator will work without it.
I'll try it out in my branch 09:58
The special translator.pl exceptions need to be factored out to the rules file @need_enum_fix
jonathan IIRC, it's just used for building. 10:00
rurban The WMLSCript SRM::Register and SRM::Stack look also much simplier than yours.
jonathan I wrote three different ones. 10:08
They varied in complexity. The most complex one gave the best results. 10:09
rurban Now with the move to compilers/SRM the SRM .pm files do not pass perlcritic. hundreds of violations :) 10:35
jonathan Haha! 10:37
I bet many of them are style things. 10:38
rurban Stupid little style errors. This will cost my afternoon.
jonathan Oh, just add an exception for those files.
rurban But the refactoring of dotnet and WMLScript didn't break more. That's good. 10:39
jonathan Some of the coding standards tests are a PITA, IMO.
rurban I did of lot of renaming and moving in WMLScript
jonathan (Especially trailing_whitespace.t...)
rurban Most are just Subroutine prototypes and PIR code coda present' 10:40
trailing whitespace is okay (and trivial to fix)
I'll ignore those for now and finish the jvm rules. 10:41
jonathan Cool 10:42
rurban I go shopping now. bye 10:49
jonathan And I'm off to Vienna...cu

moritz how so? 11:53
NotFound Don't know. If I know, I've already wrote that way myself ;) 11:54
moritz ;) 11:55
I've seen no obvious way to make it perlish
NotFound Using shorter and more idiomatic loops, mainly. 11:56
moritz does it run yet? 11:58
NotFound The version I commited in r30817, I mean.
It runs, but I dislike to have bad style examples in examples. 11:59
moritz indeed, it runs ;) 12:00
NotFound And now you don't lose your masterpiece of art when hiding the window.
moritz list assignment would be more perlish, but that's not yet implemented in rakudo
moritz should really svn up && make 12:01

PerlJam That's why Date and Codd didn't want them

NotFound There are other features expecting to be implemented in NCI. For example, Xlib functions that returns C strings that must be freed with XFree 14:47
moritz PerlJam: just a tiny bit 14:48
PerlJam I'm taking a stab at implementing thingy**sep and I'm not sure what class of PGE::Exp to call thingy. When it's first parsed it's a PGE::Exp::Quant, but then I need to change it to something else once I realize I'm dealing with the separator version of **. What should the something else be? 14:49
basically A**B becomes A[BA]*
I think PGE::Exp::Subrule should do it, but I'm not sure. 14:50
moritz uhm, I never said I'm familiar with the internals (just with using it ;)
PerlJam heh
moritz: then, do you know of a good way to test PGE? It seems there's always an extra layer of stuff between me and it. 14:51
moritz PerlJam: t/compilers/pge/* 14:52
PerlJam I could use that for regression testing I guess, but when I ack '\\*\\*' there doesn't seem to be any tests for the version of A**B that we currently have (or what I find doesn't look like what I would expect for such tesets) 14:55

ah ... I've looked at this stuff before (the last time I mucked with ** probably) 14:57

19:16 Ademan joined 19:34 daxelrod joined
NotFound pmichaud: on your messsage on pdd23: the sub usage seems broken because the handler finder try to call a 'can_handle' method on it, and throws an exception because can not.... and from here, infinite recursion. 19:44
pmichaud oh, so it's really only working with ExceptionHandler pmcs? 19:45
NotFound pmichaud: judging by the code, no other pmc can work. 19:46
pmichaud well, my next message points out some other weirdnesses about pdd23 19:47
NotFound I've readed now.
pmichaud ick, and 'can_handle' doesn't do what I would want/expect it to do 19:48
it appears to check if the handler has been previously invoked, and returns false if it has
ahhh, very interesting. 19:51
I see how things are being handled internally.
the push_eh LABEL opcode simply creates a new ExceptionHandler
perhaps the can_handle method is what causes that handler to only be be invocable once 19:53

Tene pmichaud: that's exactly right. it's the set-integer on exceptionhandler which is used to avoid an infinite loop when throwing an exception inside an exception handler 19:55
NotFound Looks like is no exactly avoiding it.
Tene according to allison that can e removed when all EHs check the type of exception and rethrow exceptions they don't want to handle 19:56
NotFound I've goy 4819 calls in a backtrace, enough infinite for my machine.
Tene Also, I like your throw/EH api refactor proposal. That's exactly what I wanted earlier when I was working on it, but I'm not comfortable proposing architecture changes yet. 19:58
I should get over that.
pmichaud: there's some other significant weirdness with the exception system right now. 19:59
I ca show you notes when I'm back from being gone ll day.
NotFound Avoiding the method call if not found in the pmc avoids the recursion, but dies on an assertion.
pmichaud avoiding the method call is probably not the right approach 20:00
Tene The gf dragged me off to visit with her family all day today

Tene pleasedieinafire.net/~tene/parrotexceptionnotes I think was the start of working towards tickets. 20:01
I don't remember what's there right now.
pmichaud Tene: no problem re: today -- this isn't a huge blocker for me at the moment. I was starting to work towards getting break/continue/next/last/redo semantics working, but I was looking for non-label ways to do the exception handling 20:02
20:02 chromatic joined
pmichaud it is very interesting to me when an exception is thrown and a handler catches it, the handler isn't really popped from the stack (a la pop_eh) -- it's simply "disabled" 20:03

This is not what the code do.
The code first call can_handle, ane then check if it's an exception, not the other way. 20:04
chromatic There are infinite loops in exceptions right now; I think we have workarounds in place but not real fixes.
NotFound No workaround for a .sub handler.

NotFound The fail with my attempt of fix is inside args passing code, an area that I've never be able to understand. 20:08
pmichaud NotFound: I think that any "simple fix" will likely make things even more convoluted -- there probably needs to be some underlying redesign done 20:09
NotFound pmichaud: was just curiosity, anyway.
pmichaud right
NotFound kills a kitty 20:10
pmichaud I think I can get the same effect using a label-based exception handler, though
basically:
push_eh somelabel
...
somelabel:
myhandler(...)
Tene pmichaud: I've been trying to get someone else to look at this stuff for a while, so I'm interested in this discussion happening. 20:11

NotFound s/giving/given 20:15
Tene NotFound: it will once this specific issue is resolved of EHs being disabled.
pmichaud NotFound: given/when is what I was thinking about when I started looking at exceptions
Tene Although maybe I could hack around it by explicitly re-enabling the handler. 20:16
pmichaud I'm working on how to implement 'break' and 'continue'
Tene pmichaud: did you see my interp.hll-map patch?
pmichaud Tene: saw that you did one (yay!) haven't looked at the contents yet
Tene kk
pmichaud once chromatic asked about it being method-based I figured it wouldn't be all that difficult to do
Tene 3 lines 20:17
pmichaud it will probably prompt me to go back and look at HLL handling in p6object and PCT again :-)
I _think_ that is the last semi-major obstacle to getting rakudo into its own hll space
(from a design perspective, anyway. There's still a not-so-small-matter-of-programming involved.)
Tene That would be fun to work on. 20:20
pmichaud things that have to be done: (1) make p6object hll-aware, (2) symbol export/import from PCT into HLL namespaces, (3) HLL type mapping 20:21
Tene I'll be back in about 3 hours, I hope. 20:22
pmichaud okay, have fun
chromatic Tene, align the = and it looks great. 20:25

pmichaud: is there a list of what p6object needs to do re: hll-aware? 20:52
NotFound A good thing towards hll interoperability will be to have a list of languages that can use external modules with a short example. 20:54
pmichaud chromatic: yes, I think moritz and TimToady turned off the regex tests that were put in the day before 20:57
the test file needed some major refactoring, and it was really slow
moritz pmichaud: we replaced them by a different test
that has all the regexes inline
pmichaud moritz: yes, I saw that
but as of 00:00 CDT today, it apparently wasn't in the regression suite :-) 20:58

Have I mentioned today how worthless the trailing spaces test is? 21:04
PerlJam no. go ahead and mention it. :)
chromatic Worthless.
purl The US Dollar!
PerlJam Where does that meme come from anyway? I've never had a problem with trailing spaces 21:05
chromatic They're useless, but they're not actually harmful to anything.
Which, in my mind, makes them not worth testing. 21:06
pmichaud PerlJam: re: A**B in PGE -- I'm not sure that translating that into A[BA]* is the right thing
PerlJam pm: por que no?
chromatic "Oh dear, something's failing in Smolder! Oh, there's a trailing space. How useful."
pmichaud A could contain a closure or something where repeating it isn't appropriate
or a declaration
purl i think a declaration is a bit
NotFound chromatic: maybe they are not causing problems just because they are tested and cleaned.
PerlJam Hmm.
chromatic I saw nothing in the PDD about them. 21:07
PDD 07 that is.
pmichaud chromatic: maybe disable the trailing spaces test and see who complains :-) 21:08
(hint: not me)
PerlJam chromatic: what pm said. And whoever complains, beat into submission :)
pmichaud I need to switch locations -- bbiab
PerlJam (unless they can come up with a really good reason to keep the test)
21:09 Andy joined
PerlJam pm: I still think A**B should become A[BA]* and if A is a closure or something, caveat emptor (for now) 21:12
(mainly because I can't think far enough ahead to how to do it otherwise just yet) 21:13
pmichaud PerlJam: the real solution is to provide a PGE::Exp::Quant node that can do it 21:17
that's actually not that difficult
I haven't done it yet because I haven't needed it for any of the language tools, and I'd rather do it as part of the PGE redesign/refactor 21:18
but I suspect that would actually be less difficult than trying to transform (arbitrary_regex)**B into (arbitrary_regex)[B(arbitrary_regex)]*
(which would require two deep copies of the AST for (arbitrary regex)) 21:19
PerlJam heh, which is right about where I've gotten in trying to do it. 21:20
pmichaud it's easier to fix the PGE quant node :-)
PerlJam If you say so. I'm looking at it now and it looks greek so far. 21:22
pmichaud it probably deserves a special PGE::Exp::QuantExp node then 21:24
since ::Quant is really designed for numeric quantification
PerlJam so, when we get to the point of parsing the B part of A**B and realize we've got separator rather than a quantifier, is the right way to switch the object like mob = mob.'new'(mob, 'rw' => 1, 'grammar' => 'PGE::Exp::QuantSep') ? 21:27
pmichaud I'm looking at it now...
no, I think I'll want to leave it as a Quant node but give it a second child (the AST for B) 21:28
so we know it's a separator Quant by virtue of having two children 21:29
I'll have to look and see how many places the Quant nodes are being optimized out of the AST, though, and make sure that doesn't happen 21:30
(PGE recognizes things like **{1} as being optimizable)
PerlJam: if you could just get the parser to recognize A**B as being a separator quantifier, that'd be a big help. I could do the code generation from there. 21:32
also, we need to make sure that the ? and ! modifiers are in the right place -- I don't know if that's been done already
moritz: !~~ should be working again. 21:34
PerlJam pm: There are already checks to see if the first char of B is a { or a number and do something appropriate. I was going to say "if not a { or a number, then it must be a separator"

PerlJam Thinking is hard when the twins keep bringing me stuff to look at (especially when some of the stuff is semi-dangerous ... "where did you find those scissors?") 21:37

i.e., we have to know if there's whitespace anywhere around the ** 21:39

cotto_home is $P1 = new ['parrot';'exception'], $P0 an obsolete way to create a new PMC, or should it still work? 22:16
chromatic cotto_home, I don't see any tests for creating exceptions that way, but as far as I know it should work. 22:22

pmichaud ['parrot';'exception'] was speculative
it's never worked 22:33
chromatic How about [ 'parrot'; 'Exception' ] ?
pmichaud as things stand now, that won't work either, unless/until there's a ['parrot';'Exception'] class
chromatic That seems suboptimal, as does the IMCC bug with the comma.

currently any keyed values to 'new' are relative to the current HLL, always.

but that never actually happened.
chromatic cotto_home, [ 'parrot', 'exception' ] gets parsed as a slice. 22:38
PerlJam pm: how does pge handle balanced delimiters?
pmichaud PerlJam: you mean like [...] and (...)? It's built into the circumfix: processing of the OPP 22:42
so, PGE recognizes that an expression can't terminate as long as a circumfix remains open.
