| jnthn | But we use :sym<whatever> generally, not sure how far nqp supports doing otherwise. | 00:01 | |
| But then you can use <sym> inside the regex | 00:02 | ||
| arnsholt | Only one way to find out, I suppose | ||

|
|||
| moritz_ | jnthn: however you confused 'is rw' with 'is capture' or \ | 13:20 | |
| jnthn: Marking a parameter as C<is rw> means that you are allowed to modify the | |||
| argument that was passed in. Doing so modifies the original thing that was | |||
| passed. If a literal or some other constant value was passed in, then this | |||
| will fail. | |||
| actually with 'is rw' the binding of a read-only value should already fail | |||
| jnthn | Ah, hmm.. | ||
| Yeah, that wants a tweak to make it clear that it fails to bind, not that it fails to assign. | 13:21 | ||
| btw, "is parcel" is the synonym for \ rather than "is capture", iirc. | 13:22 | ||
| moritz_ | I can add that | ||
| ah, ok | |||
| jnthn | Go aheaed. :-) | ||
| But I think we keep "is rw" for now. | |||
| And just explain what it does. | |||
| moritz_ | aye | ||

| ash_ | so... anyone know how P6Opaque objects look under the hood? basically are the a map of names to properties? | 20:50 | |
| moritz_ | they are like a locked hash of attribute names => attribute containers | 20:51 | |
| ash_ | in my nq-nqp i am trying to figure out how to make my objects, under the hood, and i was thinking of simply a hash, but there may be some attributes that need special treatment (like the id?) figured rakudo's already made the right design decision on this one | 20:53 | |
| moritz_ | you might need some additional meta data, unless you store that in some other part of an object | 20:54 | |
| like "what type do I belong to?" | |||
| which is basically .WHAT | 20:55 | ||
| bed & | |||
| colomon | o/ | ||
| jnthn | ash_: I don't particularly regard Rakudo as having it right. | 20:56 | |
| ash_ | the hash I was thinking of storing things like "&foo" for methods, and "$a" for an attribute, since they are all generic objects | 20:58 | |

nihiliad joined
|
|||
| ash_ | should any of them be ported into nqp? just curious, or are they to much ingrained into rakudo and/or outside of nqp's scope? | 21:12 | |
| bkeeler | Could probably be backported | ||
| jnthn | Just because it could be doesn't mean it should be though. :-) | 21:13 | |
| There's value in NQP being small. | |||
| bkeeler | There might be value in being able to use @foo in a grammar though | 21:14 | |
| jnthn | Yeah | ||
| I guess it's on a "do we have a use for it" basis. | |||
| Thing is, porting NQP is the first step to adding another backend to Rakudo. | 21:15 | ||
| Everything you add to NQP potentially makes that step harder. | |||
| bkeeler | True | ||
| ash_ | hey, if i get my nqp working, then i could maybe run parts of rakudo (the ones without pir) | 21:16 | |
| jnthn | ash_: You'd have a decent shot at Grammar.pm and, if the PAST node types were defined, Actions.pm too. | ||
| But yes, the rest of the glue is another matter. | |||
| bkeeler | PAST could certainly use being more abstract than it actually is | 21:17 | |
| There's rather a lot of pirops and inlines | |||
| ash_ | my goal is to, when I am done, have my nq-nqp run the nqp Grammar.pm and some of the nqp Actions.pm (it uses pir in it a bit, so i'd have to re-do that) | 21:18 | |
| jnthn | inlines are a problem | 21:19 | |
| pirops less so | |||
| ash_ | i don't know if i'll get to that anytime soon, but hey, its a goal :P | ||
| jnthn | If you read pirop as "vmop" or some such, it's not so bad. | ||

snarkyboojum left
|
|||
| sorear | jnthn: first line of a multi-line explanation | 21:22 | |
| ash_: P6Opaque is a PMC header + attributes; the attributes reference a ResizablePMCArray -> attribute record -> PMC* array | 21:23 | ||
| the P6Opaque also references the class, which references a name->offset mapping | |||
| so | |||
| $object.!slotname | |||
| 1. Get the class from $object | |||
| 2. Look up !slotname in $class's layout hash | 21:24 | ||
| 2. Get the storage pmc array from $object | |||
| 3 | |||
| 4. $storage[$index] | |||
| jnthn | fwiw, that's liable to change. | ||
| bkeeler | 5. PROFIT!!! | ||
| sorear | jnthn: "Opaque" kindof implies that | 21:25 | |
| jnthn | Aye. | ||
| I specifically meant in Rakudo though. | |||
| :-) | |||
| After R*, mind. | |||

|
|||
| jnthn | P6opaque today is basically a thin veneer on Parrot's Object / Class PMCs. | 21:26 | |
| It's good enough for now. | |||
| But throws away too much stuff we statically know in Perl 6. | |||
| If I was starting from scratch, I'd not copy what Rakudo does today. | 21:27 | ||
| Attribute storage wants to be some first level, per-class structure | |||
| And that structure has the attributes | |||
| Most accesses can be done by offset | |||
| With a hash to offset as a fallback. | |||

| sorear | I'm trying to implement tiebacks. I've got all the association stuff worked out, except for the minor issue where the PMC side gets garbage collected | 22:21 | |
| I'm imagining I want something like - void Parrot_pmc_register(PARROT_INTERP, void *cookie, PMC *target); void Parrot_pmc_unregister(PARROT_INTERP, void *cookie); PMC *Parrot_pmc_get_registered(PARROT_INTERP, void *cookie); | 22:22 | ||
