| lizmat | because optional named arguments are *not* part of dispatch decisoins | ||
| *decisions | |||
| grondilu | you mean optional positional arguments? | ||

||
| lizmat | m: m: say class { has %.h; multi method new() { "why am I exectuded?" }; }.new | ||
| camelia | why am I exectuded? | ||
| lizmat | so the optional named argument doesn't enter into the decision | ||
| by making it a multi, you're adding it to the existing candidates | 12:13 | ||
| grondilu | fine. I'm not sure how to do what I want to do now. I'll figure something I guess | 12:14 | |
| lizmat | add a proto | ||
| grondilu | I can't add a proto to new, can I? | 12:15 | |
| lizmat | m: m: say class { has %.h; multi method new(Mu:) { "why am I exectuded?" }; }.new | ||
| camelia | Ambiguous call to 'new(<anon|1>: )'; these signatures all match: (Mu $:: *%attrinit) from SETTING::src/core.c/Mu.rakumod line 139 (Mu $:: *%_) from <tmp> line 1 in block <unit> at <tmp> line 1 |
||
| lizmat | ok, there's your answer | ||
| m: dd $_ for class { has %.h; multi method new() { "why am I exectuded?" }; }.^find_method("new").candidates | |||
| camelia | multi method new (Mu $:: *%attrinit) { #`(Method|6475715608480) ... } multi method new (Mu $:: $, *@, *%_) { #`(Method|6475715608616) ... } multi method new (<anon|1> $:: *%_) { #`(Method|6475715339600) ... } |
||
| lizmat | the other candidates have Mu: as the invocant marker | 12:16 | |
| your additional :new" has Any: as the invocant marker, which is narrower | |||
| re your question about proto: "new' is not different from any other method, nothing magical about it | 12:17 | ||
| so yes, you *can* add a proto method new(|) {*} | |||
| to shadow the .new provided by Mu | |||
| grondilu | m: say class { has %.h; proto method new(|) {*}; multi method new($x = Any) { "why am I exectuded?" }; }.new: h => %(foo => "bar") | 12:18 | |
| camelia | why am I exectuded? | ||
| grondilu | I don't get why adding a proto would help | ||
| lizmat | well, what are you trying to achieve then? | ||
| the execution is legit, as methods always have an implicit *%_ in their signature | 12:19 | ||
| and in this case, that eats the named "h" argument | |||
| grondilu | oh | ||
| lizmat | and since the positional is optional, it can bind the argument capture to the signature, so dispatch will work | 12:20 | |
| grondilu | let me tell you what I want to do : it's for my Chess module. | ||
| I want a Chess::Position class that accepts a FEN as argument for the constructor | 12:21 | ||
| FEN is a Str, basically | |||
| lizmat | yes, I recently read a blog post about that :-) | ||
| grondilu | but I want the constructor to be able to be called with a default FEN (the start position). | ||
| lizmat | right | 12:22 | |
| SmokeMachine | m: say class { has %.h; multi method new($x = Any, *%_ where *.elems = 0) { "why am I exectuded?" }; }.new: h => %(foo => "bar") | ||

||
| grondilu | yet I also want to access the default constructors, the ones with named arguments. | ||
| SmokeMachine | :( | ||
| lizmat | m: method new($foo) { self.bless(:$foo) } | 12:23 | |
| camelia | Potential difficulties: Useless declaration of a has-scoped method in mainline (did you mean 'my method new'?) at <tmp>:1 ------> method<HERE> new($foo) { self.bless(:$foo) } |
||
| lizmat | would that work for you? | ||
| the named arg handling of Mu.new is basically a frontend for a call to .bless | |||
| grondilu | I guess I should review bless | 12:24 | |
| lizmat | method new($foo) { self.bless(:$foo, |%_) } # better, also passes any named args | ||
| Geth | ecosystem/main: 602ab05f92 | (Elizabeth Mattijsen)++ | META.list Remove App::jsonv It is broken, doesn't produce much functionality, should probably be an installable script with e.g. JSON::Fast |
12:25 | |
| grondilu | `self.bless: |%_` should work | ||
| lizmat | well, that's basically what the default .new does | 12:26 | |
| grondilu | so maybe instead I could use nextsame or something? | ||

||
| grondilu | ^that seems like what I need | 12:28 | |
| lizmat | you want to be able to call Chess.new with an optional positional argument that maps to one of the attributes in the class | ||
| is that correct? | |||
| grondilu | no | 12:30 | |
| the optional argument has nothing to do with any attributes of the class | |||
| it's just a parameter used for construction | |||
| lizmat | what does it have to do then? | ||
| grondilu | it will be used to set the attributes | ||
| lizmat | aah.... | 12:31 | |

| the_real_pk | I want to start learning Raku and I am a user of neovim, vscode and jetbrains. I want to be able to use raku in neovim though. @bscan has created a VSCode, but I can't find a way to add raku support in neovim. Is this the right place to ask for help, or I should ask somewhere else? Another question is about the rakudo repl on WSL (linux), I get a nice icon in case there is an error, but on windows only <HERE>. Is | 23:40 | |

| bscan | The extension is a language server, so it works in neovim as well. Provides syntax checking, outline view, goto definition, and some docs. It's definitely limited in functionality relative to other language servers though, and would benefit from additional contributors. | 23:51 | |
