| pony | can you include regexes, rules, and tokens from one grammar into another? (to avoid having very large ones)? | 07:01 | |
| e.g. include number grammar in calculator grammar in compiler grammar :) | 07:03 | ||
| japhb | Inheritance works; grammars are classes | 07:04 | |
| moon-child | m: my token x { h }; grammar G { token TOP { <x> } }; grammar H { token TOP { <x> } } | ||
| camelia | ( no output ) | ||
| japhb | And as moon-child points out, lexical scope works too. :-) | ||
| pony | COOL | 07:06 | |
| cool (sorry caps) | |||
| m: grammar A { TOP { 'a' } }; grammar B is A { TOP { <A::TOP> } }; say B.parse('a') | 07:07 | ||
| camelia | 5===SORRY!5=== Error while compiling <tmp> Undeclared name: TOP used at line 1 |
||
| pony | m: grammar A { TOP { 'a' } }; grammar B is A { token TOP { <A::TOP> } }; say B.parse('a') | 07:08 | |
| camelia | 5===SORRY!5=== Error while compiling <tmp> Undeclared name: TOP used at line 1 |
||
| pony | m: grammar A { token TOP { 'a' } }; grammar B is A { token TOP { <A::TOP> } }; say B.parse('a') | ||

| patrickb | lucs: Re `rakubrew list-availiable`. The "D" marks versions for which a precompiled archive is available. This means you can use `rakubrew download` to set up such a version, which is an aweful lot faster than `rakubrew build`. I just noticed, that the docs over on rakubrew.org are stale in that respect. Will update this evening. | 07:49 | |

| Xliff | Is there a write-up on how to dynamically create a class and add it to a compunit? | 14:45 | |
| Is this possible in current Raku, or would this need RakuAST? | 14:46 | ||
|
14:49
patrickb left
|
|||
| moritz | what do you mean by "add it to a compunit"? | 14:49 | |
| Xliff | Wouldn' | 14:50 | |
|
14:50
patrickb joined
|
|||
| Xliff | I would want to have the dynamically created class become a part of the compunit it is defined in. | 14:50 | |
| Or could I just assign that class to a constant, couldn't I? | |||
| moritz | yes | 14:51 | |
|
14:51
cbk joined
|
|||
| Xliff | moritz: So how do I go about creating a class type? | 14:51 | |
| And then creating the constant that goes with it | 14:52 | ||
| moritz | see docs.raku.org/type/Metamodel::ClassHOW if you want to create a class | 14:53 | |
| call new_type to create the class | |||
| add_method to add methods | |||
| etc | |||
| in the end, call compose | |||
| Xliff | OK. | 14:54 | |
| moritz | and assing it to a constant just constant MyClass = do { code that generates the class goes here } | ||
| and have the class be the last expression | |||
| or | |||
| Xliff | Yes, but the constants are also created dynamically. | ||
| Which means their names are going to come from a string | |||
| And I want it to behave as if they were statically defined. | 14:55 | ||
| moritz | then you probably need to add them to the symbol table | ||
| Xliff | Which means no sigil. | ||
| moritz | not with the "constant" declarator | ||
| Xliff | Is there another way? | ||
| moritz | why do you want another way? | ||
| Xliff | Can I dynamically create a sigil-less identifier and package that with a compunit? | ||
| moritz | ::{$name} = 42 | 14:56 | |
| Xliff | So I want to dynamically create "myType" from data. And then use it in code like "my myType $a .= new" | ||
| moritz | that's how I understood your question | 14:57 | |
| Xliff | OK. Thanks. I appreciate the advice. I just need that last piece, I think. | ||
| moritz | the thing is, the code that wants to use myType needs to know myType at *its* compile time | ||
| so you could have at the top of the usage a "use TypeGenerator;" | |||
| and that uses and compiles TypeGenerator, which could dynamically generate the types | 14:58 | ||
| (the nesting of run time and compile time can be confusing at times) | |||
| Xliff | Actually, I was hoping I could create these at BEGIN time, serialize them in .precomp, then use them like regular types at runtime. | ||
| moritz | that might work as well | 14:59 | |
| Xliff | All of the data required to create these types exists at compile time. | ||
| I just don't want to have to break them down and create them by hand, if possible. | |||
| moritz | caveat: all my meta model hacking days are years in the past, so stuff might have changed (but probably not for the worse :D) | 15:00 | |
| Xliff | Take this for example. I have this exemplar class as: "class DialogClassPart is repr<CStruct> is export { has XtPointer $.extension; }" | ||
| lucs | patrickb: As documented, I placed in .zshrc the ï½¢eval "$(/shome/lucs/rakubrew/bin/rakubrew init Zsh)"ï½£ line, but unfortunately, .zshrc is not sourced when a shell is launched from a script, so in that case, the PATH is not adjusted and raku is not found. | 15:01 | |
| Xliff | However there are more distinct classes that look exactly the same, just with a different name. | ||
| So there's: GripClassPart, ListClassPart, MenuButtonClassPart, PannerClassPart, etc... | |||
| lucs | patrickb: Any special reason that line wouldn't be better placed in .zshenv? | ||
|
15:01
Juerd left
|
|||
| Xliff | All with the same definition. | 15:01 | |
| lucs | (Appears to work when it's there.) | ||
| Xliff | Is there a way I can create all of those classes from the first one via nqp or meta programming? | 15:02 | |
|
15:03
Juerd joined
|
|||
| melezhik | how can I refer to `#` in regexp by code? | 15:04 | |
| moritz | Xliff: I have too little up-to-date experience to tell | ||
| melezhik: I don't understand the question | |||
| melezhik | I want to say `"# hello" ~~ /'#'/` but I can't use `#` in regexp literally | 15:05 | |
| Xliff | moritz: OK, fair enough. Still, your advice has been invaluable. Have any idea who else I should ask? | ||
| moritz | m: say '# hello' ~~ /'#'/ | ||
| camelia | ( no output ) | ||
| patrickb | lucs: I'm not that familiar with zsh and when which of those files is sourced. rakubrew is fine with being initialized multiple times. So it doesn't hurt to put it in a script that is potentially sourced more than once. | ||
| moritz | melezhik: the bot seems to be b0rked, /'#'/ seems to work just fine for me | 15:06 | |
| melezhik | I'd like to have an equivalent regexp detention without `#` sign | ||
| moritz | \c[NUMBER SIGN] ? | ||
| \c[NUMBER SIGN] ? | 15:07 | ||
| melezhik | yeah, something like that, thanks! | ||
| patrickb | IIRC The docs now say to use .bashrc instead of .bash_profile for the same reason. (I think .bashrc is called on every new (sub)shell, while .bash_profile is called less often. Or something along those lines.) | ||
| lucs: So .zshenv is called more often than .zshrc? | 15:08 | ||
|
15:08
Juerd left

|
|||
| lucs | It's called when a script shells out, contrary to .zshrc. | 15:12 | |
| patrickb | lucs: Ah, so it might actually make sense to add it to both? | ||
| have to leave for a bit... | |||
|
15:13

|||
| lucs | patrickb: I believe having it only in .zshenv is sufficient (like perlbrew does), but I'm not sure how to test it adequately. | 15:15 | |

| Xliff | moritz: TMTOWTDI -- I used this to solve the use case I mentioned to you... | 15:16 | |
