WIP: HTML support

[KostkaBrukowa]

This is VEEERY early stage. For now the diagnostics works very well. I've written one of the handler to show you the idea and see what you think.

Things to do:

• finish all of the TODO-s
• find and fix all of the broken lsp handlers
• tests
• experimental configuration to enable this feature

#36

My proposition is to map script ranges per lines to easly eliminate non js lines without additional iterations eg:

local scripts_ranges = {
  -- line 1
  [1] = {range1, ...rangeN},
  -- line n
  [n] = {rangeN, ...rangeM}
}

with this you can safetly and fast determine lines to "emptify" without iterating over all ranges for every line

[pmizio]

When line number isn't in scripts_ranges just fast forward to emptify line. Otherwise try to monkeypatch line.

[KostkaBrukowa]

I've reversed the logic and now I'm emptying everything and then insert chars from script tags. I think it will be faster

[pmizio]

I posted few ideas how to squeeze more performance and hopefully slimplify code

[KostkaBrukowa]

FYI I've actually resigned from creating separate buffer for script content. Now I'm only rewriting didChange and didOpen requests for HTML document and it seems to be working very well

Just wanted to try this out so I selected the feat-embedded-languages branch with Packer but even though typescript@5.1.6 and typescript-language-server@3.3.2 is installed globally I'm getting this when starting neovim:

|| [lspconfig] unhandled error: ...pt-tools.nvim/lua/typescript-tools/tsserver_provider.lua:61: Cannot find tsserver executable in local project nor global npm installation.

[KostkaBrukowa]

@marlun it was very old branch, but I've merged master into in and you can check if it helped. In the past there were some issues about finding typescript exetutable, but they were fixed
Also I will add it is very work-in-progress branch and honestly I don't know what will be the future of this branch

[marlun]

Thanks, I'm no longer getting that error. I'm not sure if you want feedback on this, tell me otherwise.

Now when I hit K I'm getting:

Error executing vim.schedule lua callback: ...ools.nvim/lua/typescript-tools/protocol/html_support.lua:20: bad argument #1 to 'unpack' (table expected, got number)

My code looks like this and my cursor is on document when I hit K:

    <script>
      const input = document.querySelector("input");
    </script>
