| ron | have done similar tests under perl5 and believe perl5 resolves at compile time. | 13:45 | |
| have read that perl6 does not use bar words but class tests seem to use them. | |||
| should I start to document some of this stuff somewhere? | |||
| bar -> bare | 13:46 | ||

| ruoso | I think pugs is right in both cases... | 13:48 | |
| bare "goo" geos through standard symbol lookup | 13:50 | ||
| and it finds the closest definition | |||
| which is sub goo | |||
| ron | From what I could tell with --target=past|post|pir in last case rakudo still looking for sub and not sure whether lookup is done. | 13:51 | |
| ruoso | in that case, rakudo is presuming class must have a uppercase first letter... which is wrong iirc | 13:52 | |

|

| ruoso | or even when declaring a 'my sub' that overrides a package sub... | 14:12 | |
| or a pre-declared class... | 14:13 | ||
| and also when declaring a sub that overrides a class declaration... | 14:15 | ||
| since subs and classes can both be used without sigil (since that classes doesn't have a sigil) | 14:16 | ||
| ron | pugs: sub foo { print "foo1\n"; }; { sub foo { print "foo2\n"; }; foo(); }; foo(); | ||
| p6eval | pugs: OUTPUT[foo2ā¤foo1ā¤] | ||
| ron | in perl5 with warnings there is a sub redefined warning | 14:17 | |
| does the evalbot print warnings? | |||
| [particle] | most of the perl 6 implementations don't do warnings yet | ||

| pmurias | ruoso: why does every SMOP__Object need to have a data? | ||
|
14:18
Exodist joined
|
|||
| ruoso | pmurias, it was to allow responder interfaces to be treated as regular objects.... | 14:19 | |
| but I'm not sure anymore that this is actually required | |||
| considering that ->data is only accessed by the object itself | 14:20 | ||
| we could move the data pointer to a SMOP_LOWLEVEL_OBJECT_BASE struct | |||
| since smop_lowlevel uses that pointer to hold lock and refcnt informatoin | |||
| but that is a quite extensive refactoring... | 14:21 | ||
| pmurias | loads of search and replace ;) | ||
| ron | rakudo: say $*ERR: "HOWDY"; | ||
| p6eval | rakudo 29834: OUTPUT[Statement not terminated properly at line 1, near ": \"HOWDY\";"ā¤current instr.: 'parrot;PGE::Util;die' pc 120 (runtime/parrot/library/PGE/Util.pir:82)ā¤] | ||

| ..elf 21894: OUTPUT[Undefined subroutine &GLOBAL::infix_58_58 called at (eval 119) line 3.ā¤ at ./elf_f line 3861ā¤] | |||
| ruoso | pmurias, I'm neglecting that question because we're talking about just one pointer, and mostly because most objects so far are using it... | 14:23 | |
| (all objects that use smop_lowlevel do) | |||
|
14:24
ggoebel joined
|
|||
| ruoso | but we might get into this issue before "1.0" ;) | 14:24 | |
| pmurias, btw... about code object... I forgot one attribute when we were talking about it... | 14:25 | ||
| class Code { has $.outer; has $.mold; has $.signature; method postcircumfix:<()> {... } } | 14:26 | ||
| and I'm thinking about having signature like: | |||
| class Signature { method ACCEPTS (Capture $c) {...}; method BIND (Capture $c, LexicalScope $l) {...} }; | 14:27 | ||
|
14:27
meppl left
|
|||
| ruoso | this way we can have a lowlevel implementation of the default block signature... | 14:27 | |
| we can even compile lowlevel implementations for the Signatures we use in s1p... | 14:28 | ||
| pmurias | ruoso: i think we should try to have as little stuff in C as possible | 14:29 | |
|
14:30
iblechbot left
|
|||
| ruoso | we can have a signature compiler | 14:30 | |
| and not write it in C | |||
| instead of instantiating a Signature object, we create a new type specifically for that block :) | |||
| or re-use for identical signatures... | 14:31 | ||
| (specially the default block signature | |||
| pmurias | the JIT can wait a bit | ||
| ruoso | no... it's not just in time... it's compilation to static C code... | 14:32 | |
| s1p doesn't have a real interpreter yet... | |||
| and won't have... | |||
| it will be compiled to static C code... | |||
|
14:33
ggoebel left
|
|||
| pmurias | ruoso: what do you mean by a real interpreter one which compiles and runs lines one by one | 14:34 | |
| ? | |||
| ruoso | I mean... ( $_ is rw = OUTER::<$_> ) would be compiled to a smop responder interface that implements ACCEPTS and BIND for that specific signature... | ||
| pmurias | re real interpreter i reread and got it | 14:35 | |
| i'm actually thinking of taking the .pbc spec and adapting it to smop | |||
| but it's just an optimalisation so it can wait | 14:36 | ||
| ruoso | I think so | ||
| ron | so I'm guessing that there may need to be some kind of compile time symbol table lookup for some of these bareword cases ... If anyone actually knows I'm curious ... | 14:37 | |
| ruoso | ron, after bootstrapping, yes... but s1p is a 1st stage compiler that won't have this kind of lookup... | ||
