How to use 'bzl' (starlark) LSP

[DanielKongsgaard]

:Mason has a language server called bzl, but when I try to ensure it is installed with mason-lspconfig I get:

[mason-lspconfig.nvim] Server "bzl" is not a valid entry in ensure_installed. Make sure to only provide lspconfig server names.

Also, I tried to set it up without mason-lspconfig, but had no luck so far.

How am I supposed to setup this LSP?

I figured out that I can set it up so it works with the following in .config/nvim/after/ftplugin/bzl.lua:

-- setup bazel/starlark lsp
if vim.fn.executable('bzl') == 1 then
    vim.lsp.start({
        name = 'Bazel/Starlark Language Server',
        cmd = { 'bzl', 'lsp', 'serve' },
    })
end

but I am not sure how to best give root dir.

If anyone has any experience with setting this LSP up I would still like some feedback though.

Way late to the thread, but using starpls (https://mason-registry.dev/registry/list?search=bazel#starpls) directly for me works. You can just do:

:MasonInstall starpls

or

    mason_lspconfig.setup({
    ...
      ensure_installed = {
        "starpls", -- Bazel
      },
     ...
    })

I also ended up switching to starpls since it worked better last I checked.
