fglock it's a multi token 15:43
dlocaus ok, I've made that change on my own code, but it breaks
on the empty braces { }
if I put a "1;" in there it works, well it parses at least.
fglock how about { '' } 15:44

fglock reverting to past versions works, but it is very tedious 15:47

pugs_svn r18803 | pmurias++ | [kp6] commented out COMPILER::begin_block() in proto - it might be better to solve the runtime issues before the compile time 16:29
pmurias dlocaus: MultiToken should be only used for 'proto token {}' 16:30
dlocaus Yes. 16:31
Isn't that what I did?
I've traced the compilation problem to compiled/perl5-kp6-mp6/lib/KindaPerl6/Runtime/Perl5/Pad.pm: my $source = $data->{_dispatch}( $data, 'perl' )->{_value}; 16:32
$source returns { ... } instead of "{ }"
pmurias begin_block compiles and runs the ast at compile time 16:33
is ... a compile error in kp6? 16:34
dlocaus I think so 16:35
16:36 Silence joined
pmurias you can fix it ;) 16:36
16:36 IllvilJa left
dlocaus the compiled/perl5-kp6-mp6/lib/KindaPerl6/Grammar/Sub.pm file code expects "{}" not "{ ... }" as produced by compiled/.../Pad.pm 16:36
pmurias Multi.perl would have to serialise it correctly
itself 16:37
commenting begin_block out is the best option untill it does
dlocaus pmurias: I'm sorry, I don't get what you are saying? 16:38
fglock buggy code is easy to find - commenting out code creates hard to find bugs 16:39

dev.pugscode.org/browser/v6/v6-Kind...P.pm#L1451 16:43
There's the bug
lambdabot tinyurl.com/24j5wb
dlocaus ::Code->perl() returns "{ ... }", but the grammar spec requires "'{' <.opt_ws> '}'".
fglock it's not a bug - it's a TODO
pmurias dlocaus: the bug in Multi.pm 16:44
kp6 should handle ...
dlocaus looks lost 16:46
pmurias dlocaus: sorry the ofenting .perl is in MOP
dlocaus: "..." is valid perl6

pugs_svn r18804 | pmurias++ | [kp6] uncommented the line fglock requested, Multi and MultiToken exist at compile time but are empty 16:49
pmurias the syntax error happened in begin_block()
dlocaus so, "<.opt_ws>" should also handle "..."
pmurias dlocaus: no
16:50 jjore-w joined
pmurias the grammar used by kp6 isn't the offical perl6 grammar 16:50
dlocaus The only other option is to replace the '{' <.opt_ws> '}' with '{' <.opt_ws_or_code> '}'
pmurias that's STD
it wouldn't help at all
dlocaus: you mean in token proto 16:51
dlocaus pmurias: yes.
pmurias dlocaus: token proto parses ok
dlocaus no.
pmurias it calls begin_block($ast)
dlocaus: yes 16:52
dlocaus That is what started me on this.
pmurias the ast is then executed
16:52 IllvilJa joined
pmurias the side effects are serilised as perl6 and turned into ast 16:53
the were serilised by calling .perl which returned invalid perl6 code

dlocaus moritz_: all perl6 files beginning with "use v6-alpha;" have to be compiled with mp6 right? 19:42
moritz_ dlocaus: no
dlocaus: it's just a flag that says it's not perl 5 19:43
dlocaus ok
19:43 jisom joined
moritz_ because a perl 6 compiler has to assume perl 5 syntax on any file it reads, unless it encounters a 'use v6;', a 'module ...' or a 'class ...' statement 19:44
dlocaus wasn't that up for debate?
weather or not to allow the perl6 compiler to parse perl5? 19:45
moritz_ well, maybe. But the current specs says "perl5 until told otherwise"
dlocaus and eval "$perl_code_here"? 19:46
19:46 drupek12 joined
moritz_ if called in p6, it evals p6 19:46
if called from p5, it evals p5
if called from python... guess what ;) 19:47
dlocaus I mean, if you eval " .. code .. " you have to have the compiler too to compile what ever is in that string. 19:48
if you only have the parrot interperter you cannot compile.
moritz_ of course
dlocaus hurmm... ok
moritz_ that's why you have to compile the whole compiler into PIR if you want to distribute it separately
dlocaus thinks the parrot people really have their work cut out for them.
