Editor support for vscode

[Victorious3]

I thought I should post this here since the repo contains grammars for other editors, and it could be useful to someone.

I've written a vscode addon a while ago to support syntax highlighting and eventually autocompletion for symbols: https://github.com/Victorious3/vscode-TatSu

It is quite involved, but sadly unfinished since I discovered a glaring issue in vscode that makes writing it a complete pain.

Waiting for this PR: microsoft/vscode-languageserver-node#367
And this: microsoft/vscode#580

Apart from that, writing typescript is only marginally less annoying than writing Javascript so my motivation to enhance it is limited.

It's not on the Marketplace yet since its performance characteristics are a bit... questionable (due to the issue mentioned above, it parses the entire file on every edit) and its lacking support for goto symbol.

Please add a pull request for this @Victorious3, so it gets included in the next release. It's the best way to gather help for finishing the work.

@apalala Aight, I can do that. Would you publish the addon when its done? I'm thinking having a separate repo for this as well as the other editor support might be useful.

I think I can also include my updated tmlanguage file since it contains some improvements over this one.

[apalala]

We'd publish it right-away, with a caveat.

[Victorious3]

I'm not sure how to include this into the project structure...
I would use a seperate repo, with a submodule perhaps?
Feel free to pull it from my repo and integrate it as you see fit.

[apalala]

Oh! It's not a single program file, but a complete VS project. We should mention it in the documentation, then.

@Victorious3 does your proof of concept include a working language parser?

I'm trying to generate an abstract syntax tree from a TatSu EBNF on the client-side (JavaScript).

[Victorious3]

@FezVrasta No, I'm using the textmate grammar, its not a complete parser, only enough to provide syntax highlighting
