ruoso @tell pmurias I think I know how to solve the issue, we could make p6opaque intercept the FETCH calls based on some attribute that could be set in some special cases, like a specific role or something... 00:58

pmichaud slavik: <blah>? means that any captured value goes into an array, yes. 02:16
slavik pmichaud: right, but if I do <blah> then $/<blah> will hold it, not $/<blah>[0] like it is with <blah>? 02:26
IMO, since <blah> is said to be optional with '?' why should it go into an array?
pmichaud that's what the spec says 02:27
slavik also, I am having trouble with assertions ...
I see
pmichaud but it's really that <blah>? is the same as <blah> ** 0..1
i.e., it's a quantifier, and all quantified captures become an array
slavik ahh, I see, makes sense now
token port { (\d ** 1..5) <?{1 <= $0 < 2**16}> } 02:28
does that make sense?
rakudo tells me that the line is not terminated properly 02:30
rakudo: token port { (\d ** 1..5) <?{1 <= $0 < 2**16}> }

slavik also, I forget how to put a character into a token that should not be captured ... 02:31
<.':'> ???
so then * and + become ** 0..inf and ** 1..inf respectively? 02:35

Has anyone got time for a question regarding building pugs from the public svn repository?
slavik I used the cabal system 13:26
lambdabot slavik: You have 1 new message. '/msg lambdabot @messages' to read it.
slavik @messages
pernod ok
lambdabot pmichaud said 7h 40m 34s ago: code assertions aren't implemented in rakudo yet.
masak pernod: I also used Cabal. you tried that?
pernod So the plain svn $repository;perl Makefile.pl;make is not the way to go?
Nope.
I'l have a look at cabal then.

masak pernod: I don't know if making from svn works again. it used to not work, at least.
pernod I saw something on the pugsblog that it should be working, but it was two months ago ...

pernod Yup 13:28
masak or are you updating?
strange...
pernod Indeed!
Things didn't work, so I thought I'd try a fresh checkout.

pernod ok 13:29
pmurias pernod: that's definitely a svn bug 13:31
pernod Ok.
I just used the default command line svn in Mac OS X.
I'll see if updating svn helps.
Thanks!
pmurias pernod: usually svn screws up the .svn dir and prints stupid error messages, but a problem with a fresh checkout is strange 13:34
masak and concerning.

Let me get back to you pmurias, and thank you for your suggestion. 14:17
pmurias pernod: you shouldn't thank me just yet my suggestions are most likely bogus 14:19
;)
pernod pmurias: shotgun debugging for the win! 14:20
slavik my suggestion is to dump OSX and use a real OS :P 14:21

pernod pmurias: I'm still waiting for my subversion client to be up to date. 14:32
ruoso pmurias, Perl 6 code uses FETCH all over the way... including while building the object...
pmurias ruoso: hi
ruoso pmurias, hi
pernod The default svn on os x is 1.4.4, so I thought I'd get the latest subversion before anything else. 14:33
pmurias ruoso: if we make sure the object is always in a container it should work
ruoso pmurias, it ends up being by itself at some point... 14:34
I think intercepting FETCH calls in p6opaque might be sane
we just need to find a way to discover when to intercept and when not to intercept 14:35
pmurias which is where the insanity creeps in
ruoso maybe we simply have a switch 14:36
and it by defaults intercepts the FETCH
pmurias ruoso: have you seen my latest change having is rw instead of is copy as the default?
ruoso it doesn't solve the problem
because it ends up being by itself at some other point 14:37
pmurias not nessesarly
ruoso well, I tried that path, and it always got there at some point
pmurias if we put it in a scalar using VAR($foo).STORE(...)
ruoso pmurias, I have to leave now (lunch), and might not get back today, so feel free to try that 14:38
but I should warn that I don't see a very near exit... 14:39

well worth a look.
[particle] that's always nice to see :)

21:20 stas left
masak guess he went to read the spec. 21:21
slavik is rw is kind of ambiguous ...
masak slavik: how so?
slavik well, "is rw" is that inheritance or attributes? 21:22
or do classes HAVE to start with a capital letter?
masak neither.
it's a trait
slavik: no, why would they?
slavik meant trait by the work attributes
so, how do you distinguish between the two 21:23
masak slavik: the member variables are called attributes in Perl 6.
slavik err?
masak slavik: class inheritance is only done when declaring the class.
there's no ambiguity.
slavik right
look at the code 21:24
masak looks
slavik it says "class Point is rw { .............. }"
masak ah.
slavik and rakudo thinks that rw is a class, not an attribute type thing
masak well, as long as there's a class called 'rw', then it's no problem :)
slavik so that is indeed not the intended syntax 21:25
the traits have to be rw, correct?
masak depends on what was intended.
slavik: what do you mean, have to?
slavik ie: class Point { has $.x is rw; } 21:26
masak you can have a trait which is not called 'rw'.
slavik: that's legal, but omitting the 'rw' trait is legal, too.
21:26 rindolf left
slavik masak: but the point class there, the idea behind the code is to declare it as a C struct (complete read write on everything) 21:27
masak slavik: (note: 'is rw' is called a trait, '$.x' is called an attribute in Perl 6)
slavik right
masak slavik: if that's what was intended, that is indeed not the intended syntax.
slavik masak: exactly
masak rakudo: my $a = " foo "; $a .= subst( / ^ \s+ /, '' ) 21:28
