TreyHarris anyone here who has a moment to look at a few lines of MMD logic to see if it's sane? 00:01
00:04 weinig is now known as weinig|bbl
markstos TreyHarris: Still there? I'll look at MMD 00:11
You might check examples/dispatch_quiz.pl though-- it shows some cases that I think are bugs. 00:12
pasteling "TreyHarris" at 216.254.17.198 pasted "markstos: have a look" (16 lines, 412B) at sial.org/pbot/19457 00:13
markstos will do. give me 5.
TreyHarris thx
00:15 buetow joined
markstos TreyHarris. I think it's sane, but pugs is buggy WRT () vs (*%h) 00:15
That's one of the cases in the dispatch_quiz.pl
I would be more assertive about creating related tests, but the spec is not detailed about how MMD happens with optional and slurpy fields. 00:16
I asked p6l to clarify recently
and you may recall I also added some related language to mmd-draft.txt
To get code working, I combined the () and (*%h) cases into one method ... 00:17
with an "if %h { ... }" clause.
TreyHarris right. this is for a draft i'm writing, so it doesn't have to work :-)
yet. 00:18
thanks much
markstos Let me check the dispatch quiz result.
Those are actually the first a second tests in the quiz. Pugs does different things for subs and methods in that case! 00:19
TreyHarris *grin* 00:20
markstos The subs case looks correct, it sends (a => 'b') to (*%h).
the multi method case sends ( a=>'b') to (), which seems ... wrong.
TreyHarris yes 00:24
markstos I'll go ahead and poke around to make sure it is covered by a test.
00:25 hikozaemon joined
markstos Yes, it looks like I already made a failing test for it in t/oo/methods/multi.t 00:26
(And 3 other cases from the quiz!)

nothingmuch wow, adding roles made it even slower =) 01:16
TreyHarris whoo-hooh! push for O(Inf)! 01:17
nothingmuch ;-)
push for correctness actually
i am explicitly not memoizing anything
nothingmuch.woobling.org/MO/t/roles.t 01:18
TreyHarris O(Inf) is just, after all, O(c), which is equivalent to O(1)....
nothingmuch heh
porting this 1:1 to haskell should speed it up a bit
i also want to wirte Moose::Aspect::Memoize 01:19
which implicitly declares attrs over methods
and does auto caching
with lazy => 1
and auto expires caches using triggers
which should bring this impl closer to the haskell version in terms of O(n) complexity

markstos Shouldn't it throw an error to try to delete something that's not a hash or array element ?
markstos checks the spec
I don't see this behavior spec'ed. I'll review the tests, and test for the kind of msg Perl 5 would throw: 02:16
delete argument is not a HASH or ARRAY element or slice

TreyHarris ok, wasn't sure it was allowed to leave out the space between the subname and the sig
gaal you are, but the style used thoroughly in existing code is to use the space there. 05:57
this makes me wonder though if the space is optional here: sub foo:($a) { ... } 05:58
(a Sig in a sub decl really is a Sig, dropping the colon is "just" an abbreviation) 05:59

TreyHarris gaal: how do I refer to the current type symbolically? "my $?CLASS $x" doesn't work, nor would I expect it to... 06:58
gaal jdv79: it's a mechanism for a default entry point to executables, that takes care of command line options automatically
TreyHarris: in signatures? 06:59
TreyHarris signatures or storage defs
gaal you need to already have bound a tyvar, so this:
:(Mammal ::T $x, ::T y) 07:00
will bind ::T to say Moose at call time
er, that's $y in there
I don't know how to bind a tyvar in other scopes so that your example works
TreyHarris hmmm. i should be able to write class Moose { method clone ( --> <mumble>) { ... } } without making <mumble> eq "Moose" 07:03
I kinda think 'Self' (capital S) should work 07:05
or maybe SELF
gaal better ask the oo guys. from my unwashed viewpoint, I don't see that Moose should know how to clone arbitrary types correctly, though sure, superficially it should be able to. 07:06

gaal it's a callconv question, I guess. you can't do this after all: foo( self => $obj ) 08:16

audreyt gaal: oy. the idea is that "make ghci" should ignore embedding 12:36
and _not_ link in Perl5_stub 12:37
i.e. you never get p5embed in ghci
can you simply remove the _stub.o in src/?
"make ghci" uses src/ to put the .o files
normal "make" uses dist/build/
totally separate spaces

Limbic_Region looking particle though I will only be guessing if I offer any advice 16:35
[particle] yeah, i figured it was unrelated to your error
Limbic_Region particle - you could try disabling perl5 embedding 16:36
since that is where it is failing
set PUGS_EMBED="!perl5" 16:37
[particle] i guess it's defaulting to that embedding
i haven't set any special env vars
Limbic_Region yes, p5 embedding is enabled by default now
you have to specifically tell it not to if you don't want it
this btw is not a fix, just a workaround (presuming it works)
[particle] do i need makefile.pl again? 16:38
Limbic_Region the issue apparently is with some conflicting header files
particle, I never risk it - I always realclean;svn up;makefile;etc
[particle] perhaps it's perl-version dependent?
i'm on 5.8.6
Limbic_Region AS Perl?
[particle] yep
Limbic_Region I believe it has been certified to be working with AS and Vanilla Perl
not sure about versions 16:39
[particle] i'll kick the certifier :)
Limbic_Region in any case make unoptimized is easier spelt make fast
it appears to be an issue with conflicting header files
[particle] i'll retrain my fingers :)
Limbic_Region the certifier likely didn't try with ghc 6.4.1
[particle] i'm hoping to go direct to 6.6 16:40

Limbic_Region xerox - what kind of shell? 16:51
sorry, was AFK
xerox bash
hmm
sh in fact.
Limbic_Region shouldn't matter much
let me check - been a while since I did any shell programming
xerox For me too :( 16:52

xerox I ought to do a script that lets people add packages to hackage, in order to use them with cabal-install. 16:52
Limbic_Region $* is all of them right?
so wouldn't it just be $# ?
xerox That's right! Thank you. 16:53
Limbic_Region no worries - had to stop and think about it

xerox Limbic_Region: still around? 17:09
Limbic_Region in and out
but if you have questions I will stick around
xerox Yes! thank you. 17:10
Limbic_Region shoot
xerox I need to do these steps:
./cabal-put foo-1.0.tar.gz
1. check the filename format is correct: PACKAGE-VERSION.tar.gz
2. check that it unpacks to (case-sensitively) the same PACKAGE-VERSION/ dir
3. check it exists (case-sensitively) PACKAGE-VERSION/PACKAGE.cabal 17:11
4. check .cabal contains 'name: PACKAGE' and 'version: VERSION', 'name' and 'version' case-insensistively (one can use Name or name, and so on), while PACKAGE case-sensitively
Limbic_Region is there a 4?
let me know when you have provided the last step 17:12
xerox 5. copy out .cabal to foo/PACKAGE/PACKAGE-VERSION.cabal and .tar.gz to the same dir. (foo is the base-packages-dir)
Done.
How would you do that? 17:13
Limbic_Region ok - so we are assuming bash/sh/ksh type shell
and sed and/or awk but no perl?
xerox Let me see
This is perl, v5.8.4 built for i386-linux-thread-multi
I can use this perl too
Limbic_Region oh, well then there is no need for a shell script at all 17:14
xerox Except I can't maintain the perl thing
But well, yeah.
Limbic_Region ok - well I will just do shell with sed then
xerox Oh well
If the perl one is easyer
*easier, go with it
You're too kind :)
Limbic_Region sed is only needed for 1 step
xerox Okay!
Limbic_Region let me throw something together
xerox I probably can manage some perl. 17:15
Limbic_Region I will do both
xerox hugs Limbic_Region
Limbic_Region you check which one you want
xerox I'm so stuck... too much higher level programming makes me unable to do this... yuck.
Heh, no pugs on monk 17:16
Otherwise we could've used perl6 ;-)

gaal xerox: option x p = p <|> return x
and <|> is mplus IIRC
Limbic_Region xerox - there is a shell script version that is pretty ugly if you ask me
I will write a perl version which should be much cleaner
xerox Limbic_Region: great!!!
Limbic_Region++
I'll be back in short time. 17:43
gaal I can of course write a combinator - but I feel like there's a native way to exploit the Maybe here...
Limbic_Region I already know the shell script is missing one command - the actual cabal-put
xerox gaal: why do you need to option Nothing . fmap Just?
gaal I *want* the parser to return a Maybe
Limbic_Region as well as step 5 - must not have copied that 17:44
gaal it's not Nothing . fmap just
xerox It's option Nothing . fmap Just :)
gaal it's option (Nothing) (fmap Just someRule)
xerox Yeah, the point is someRule I mean.
Just make someRule fail with Nothing, i.e. return a Maybe a?
Limbic_Region: right, the actual cabal-put *is* step 5 right? or what do you mean? 17:45
Limbic_Region xerox - let me finish the perl version then I will rectify any problems with the shell version 17:46
xerox nods
gaal xerox: it compiles, but does not work :/ 17:48
xerox Aw.
Hmmmm.
gaal that is, having the rule 'return Just x' instead of 'return x'
because apparently option catches the failure? 17:49
xerox (option x p) tries to apply parser p. If p fails without consuming input, it returns the value x, otherwise the value returned by p.
I think the `without consuming input' part is the key. 17:50
gaal but my rule has a 'try' combinator around it... 17:51
it doesn't consume input when failing.
xerox Right, I was going to suggest that.
gaal I think I'll just write a maybeRule function that does thi 17:52
s
:pl maybeRule r = option r $ fmap Just r 17:53
@pl maybeRule r = option r $ fmap Just r
xerox Strange. Cale is good at Parsec, if he comes about ask him about that.
lambdabot maybeRule = ap option (fmap Just)

Limbic_Region xerox - "copy out .cabal to foo/PACKAGE/PACKAGE-VERSION.cabal and .tar.gz to the same dir." where foo is base-packages-dir - how will I know what that is? 17:59
is it passed in as a command line argument?
xerox Limbic_Region: a variable would be sweet 18:00
It's now a subdir in my $HOME but it'll be something different 18:01
Limbic_Region what I mean is, something has to tell the script what it is
I can query the environment or it can be passed in as an arg
please disregard the shell script - I made a lot of incorrect assumptions when I wrote that
I read more carefully for the perl 18:02
xerox OK
Limbic_Region: can it be a "global" variable?
It is just a fixed directory, users aren't supposed to change it
Limbic_Region I don't care what kind of variable it is 18:03
I care how my script finds out about it in the first place
xerox Just a variable in the script, it's a "fixed" path.
Limbic_Region almost finished
xerox One writes it in the source.

gaal I wonder whether at this point it would be more fun to write the pugsy introspection interface, or to transition the the parser to use this in actual sub declarations. 18:22
xerox Back.
gaal or maybe a pretty printer, though perhaps writing the pretty printer in Perl would be a good way of testing an introspection interface! 18:25
xerox Limbic_Region: anyway, there's no such thing as cabal-put. The script *is* cabal-put.

gaal looks like a GHC bug to me
Limbic_Region except that it worked fine yesterday
gaal but I'm not sure.
Limbic_Region I will know tonight if it is related to the pugs source as what I have at home is using the same version of ghc - so I verify that it still works, svn up, and see if it starts failing 20:09
gaal the bug has festered, perhaps
Limbic_Region not that it couldn't still be a ghc bug - but if so, then it is one that just recently got tickled

xerox Question. 21:33
To check for directory existence is it:
dir "arr" if ! $dir;
Or:
die "arr" if ! -d $dir;
?
wolverian just open/glob it and check the return value. 21:34
there's a race condition in checking its existence first.
er.
oh, this is #perl6 :)
xerox Hm?
wolverian well, the advice still applies.
Limbic_Region xerox - in perl, use ! -d $dir
xerox hehe okay
wolverian die unless -d $dir; ...someone removes the directory here...; glob $dir... 21:35
Limbic_Region race conditions are not applicable here
xerox Just checking for existance and moving on.
Limbic_Region neither is portability and a half a dozen other things you might think are good ideas 21:36

wolverian: do you also know the idiomatic way to cwd to a directory and run a command there? 21:41
wolverian: I'm pretty sure it's system() for the latter part, but I don't know about the former.
wolverian { temp $*CWD = ...; ... } # :) 21:42
xerox Nice!!
wolverian no, I'm not sure if that works. it's scary.
xerox :(
wolverian I remember discussion about it.
xerox Something that works.. ?
wolverian in perl6 or perl5? 21:43
xerox perl5.
wolverian I don't think there's a neat idiom. 21:44
use Cwd qw/getcwd/; my $old = getcwd; if (chdir $target) { system command => -flags } else { die "foo" }
er, and chdir back to $old :)
xerox Yuck.
wolverian quite.
21:49 jlf joined 21:54 prefiks left 21:57 cjeris left
TreyHarris xerox: if you can stomach turning commandline processing over to the shell, you can just do 'system "cd $target && $command"'... when the system exits, you'll be back in your old cwd 22:37
xerox TreyHarris: that's what I am doing now in fact
Thanks anyway :)
TreyHarris of course, this Is Not Portable... but incantations involving system() never are
xerox Yeah
TreyHarris what wolverian describes of temporizing $*CWD is already implementable by the Synopses. I dunno if it's implementable under pugs yet 22:38
actually, i know it's not. Proxy objects aren't implemented. 22:39
