It would be really great if Raku had a really good Language Server Protocol language server.

A couple of people have made a start.

scriplit has made a vscode-specific langserver plugin based on the javascript/typescript example in the vscode docs.
And azawawi has started a langserver module, though it's not very fleshed out and hasn't had a commit since October 2018.
I think it would be a really good thing to put time into because it would help improve the Raku development experience for users of many different text editors.

On issue 19 of this repo, "Make sure that all editors play well with Raku" there is a list of text editors with their Perl 6 support. A good LSP language server would mean it's a lot easier to add that support for a quite a few of them, and that development work on a single codebase would benefit all of those LSP-based editor plugins.
Brackets currently has no Raku support, but has recently added LSP support. Sublime's isn't great, but it has an LSP plugin. VSCode and Atom and neovim and IntelliJ and Eclipse and Emacs could all benefit.

This is a great thing to have for just about any language. But with the depth and texture of Raku, having one officially-driven codebase for powering completion, navigation, hover, symbols, references and linting would be extra valuable.

I'm not sure of the actions from this issue. Probably trying to get some more people working on azawawi's module.

sorry if this isn't the right repo for this, or if i don't know what im talking about
