Implement language server for Starlark

[enriched]

First off, I'm really excited to see the Bazel team creating a repository for vscode support and I would love to contribute to it!

Secondly, Is this Repository going to be developing a Language Server Protocol implementation? Seems like it could be a great opportunity to develop a resource that could be reused in other editors as well.

Inside Google, we have an implementation of LSP in progress (with completion, jump to definition, and diagnostics). The bad news is that it relies on an internal framework. I expect it to be open-sourced early 2019, but I have little control on that.

I created this repository to publish a debugger (to execute bzl files step by step and observe variables), I hope it will be added soon. And I'd like this repository to replace https://github.com/devoncarew/bazel-code (from @devoncarew) to have everything in one place.

Thanks for the info! I'll look forward to that release in 2019 and it also sounds good to have everything in one place. Does this plan on bringing in things from https://github.com/dprogm/vscode-bazel-tools (from @dprogm) as well? That extension seems more focused on running bazel tasks.

If @dprogm is willing to contribute, that'd be great too!

(I can give write access if someone wants to help maintaining the repository)

I also like the idea of having all bazel related vscode plugins in one place. So I would definitely join and contribute.

@laurentlb is that progress published somewhere? Or if was announced in a roadmap? It would be really exciting to see a starlark LSP for vscode :)

Any update about a starlark LSP?

any update on lsp support?

[laurentlb]

No, sorry. There's some code at Google that I hoped would get open-sourced. It's unfortunately not happening.

If someone wants to work on a LSP implementation, I'll be happy to provide some guidance.

@laurentlb How significant is that internal framework? Is it possible to open source without it and then pile down on re-implementing the missing pieces? Or is forking a Python LS a better option (like https://marketplace.visualstudio.com/items?itemName=phgn.vscode-starlark seems have done?

Adding my own +1 for the LSP implementation.
