fglock pmurias: re: 'does util/build-perl5.sh use the old v6.pm or MiniPerl6 itself?' 11:08
lambdabot fglock: You have 1 new message. '/msg lambdabot @messages' to read it.
fglock util/build-perl5.sh is pre-bootstrap - it used v6.pm
MP6 needs a new build script
nothingmuch moooooo 11:12
svnbot6 r14791 | fglock++ | MP6 - util/build-perl5.sh renamed to build-with-v6.sh 11:15
fglock nothingmuch: hey 11:19
svnbot6 r14792 | fglock++ | MP6 - new build script "util/build-perl5.sh"

11:20 xinming_ joined
fglock diff -u -r lib5 lib5-new == no differences :) 11:20
nothingmuch hola fglock 11:22
fglock nothingmuch: mp6 needs a MO :) 11:23
nothingmuch =) 11:24
what is it's target language right now?
fglock nothingmuch: Perl5, Haskell, Parrot, and Javascript for now 11:25
nothingmuch i meant the major one
fglock mp6 is written in mp6, so mp6 is the major one 11:26
nothingmuch it doesn't compile mp6 to mp6 though, does it?
i mean you run mp6 through itself, and make a $x_lang "executable" 11:27
which is the best supported $x_lang?
fglock currently only perl5 is implemented
nothingmuch okies =)
so, that helps a lot
there are two ways that you can plug MO
fglock I'm working on c++ too
nothingmuch 1) push it all down to the runtime 11:28
by simply translating the metaclass mappings
and implementing a metaclass in the target language's MO impl
or (more robust, more work):
2) implement at least MO::Comple::* in MiniPerl6
and do the metamodel calcs in the compiler 11:29
emitting much more simplified responder interface calls
that's actually the original intent
but we might be able to get working code sooner by short cutting for now
fglock I like the idea of MO::Comple::* in MiniPerl6 - this make it easier to port to other backends 11:30
nothingmuch yes
this is definitely the correct way to implement it 11:31
fglock sorry - bbiab
nothingmuch is MO-perl5 published? 11:35
audreyt fglock: darcs get nothingmuch.woobling.org/MO 11:45
lambdabot audreyt: You have 3 new messages. '/msg lambdabot @messages' to read them.
Title: Index of /MO
fglock audreyt: k 11:46
audreyt: re the 'Tree' example in svn.pugscode.org/pugs/v6/v6-MiniPer...6-spec.pod 11:49
lambdabot tinyurl.com/yzs3h5
fglock would it be: ($left, $right) = ($top.left, $top.right)
audreyt sure 11:50
er wait
you are compiling mp6 to mp6?
then it's :=, not =
fglock right
audreyt otherwise yes. 11:51
and if there's not $top
but simply
(Tree ($left, $right))
then you need to gensym a $temp to hold it.
fglock is 'Tree (:$left, :$right)' better to write? 11:52
:$var is now supported
audreyt well I think it's a punning in spec 11:53
fglock actually, '::Tree( :$left, :$right )'
audreyt I think either will do
but I support that proposition that :$left looks and works better. 11:54
fglock so the exp grammar can be reused for sig - does it make sense?
audreyt that is the expectation 11:55
as sig is simply lhs of :=
and in bind we already handle the lhs-side compilation
for non-Control nodes
fglock audreyt: did you try out the native MP6 compiler? 11:57
audreyt no, sorry
I'm too busy to proc a certain event 11:58
that will hopefully stabilize tomorrow
fglock audreyt: 'sh hello.sh' will do
audreyt T:~/work/pugs/v6/v6-MiniPerl6 audreyt$ sh hello.sh 11:59
hello, World
that... was easy
nice :)
fglock is this valid p6? 'my ::Tree $top (:$left, :$right);' 12:02
nothingmuch audreyt: did you see the .pdf? 12:03
audreyt fglock: yes. 12:04
nothingmuch: no.

lambdabot You don't have any new messages.
masak is pugscode down? I can't svn-up it at the moment
fglock dmq: hi 12:18
audreyt masak: it worksforme 12:19
dmq how are tings? 12:20
i was doing battle with perl5 and how it handles \G and /g the past few days. Was wondering what perl6 does in that direction. 12:22
like could you say: $str='aabbccddeeff'; pos($str)=5; /(..)\G(..)/ and print "Before pos: $1 After pos: $2"; 12:25
and if thats ok, can you do something like /xy*\G(..)/?
broquaint That would be ace. 12:26
dmq the latter would be forbidden by me. :-)
the former would fine. 12:27
broquaint I like the idea of being able to use \G arbitrarily. 12:28
12:28 Psyche^ joined
dmq the only problem with that is you run into the problem of infinite loops, and serious performance issues. 12:28
broquaint Details, details.
dmq Yeah, well, ive been dealing with them 12:29
:-)
broquaint Ah :)
dmq like for instance its probably not cool to have pos($str)=2; @list=m/(..)\G/g; infinite loop until it sucks all available memory. 12:30
broquaint Crappy non-turing-machine computers. 12:31
dmq that was a doozy to figure out.

Reyben I open a file with something like 'open FH, "<", $filename;'. Is it possible to determine at a later time whether the FH is valid, i.e. whether the file could be opened? 13:46
svnbot6 r14798 | fglock++ | MP6 - more bind tests
Limbic_Region Reyben - this is #perl6 which is to discuss and develop the perl 6 language. Please try #perl 13:49
Reyben - in general, you should always check the return code of open my $rc = open(my $fh, '<', $file); 13:50
Reyben - then later on you can check $rc
Reyben - notice I used a lexical filehandle and a 3arg open, you should too
Reyben - now good luck and please check out #perl
Reyben Thanks. Strangely, a #perl channel doesn't currently appear on my room list, though. 13:55

wolverian anatolyv, there is only one. 21:48
(that I see.)
anatolyv wolverian: in runtime, there may be many copies of $x. for example, imagine foo calls itself recursively with depth 100, every copy has its own $x. 21:50
wolverian: by calling into inside bar() we don't give it any information on which runtime pad of foo() it should use to access $x.
wolverian it works in perl5! that's all I know! :)
anatolyv no it doesn't, that is, it doesn't return 5 21:51
