Godot WSL LSP

Simple LSP server that sits between Neovim instance on WSL and the Godot LSP server running on Windows.

This server's only purpose is to convert the Windows and WSL path back and forth, to have a seamless experience editing GDScript files on Neovim running inside WSL (while Godot is still running on Windows).

Setup

You can find more information on the entire setup process in this gist.

The updated configuration from the previous gist using this server would be:

-- after/ftplugin/gdscript.lua

local cmd = { "godot-wsl-lsp" }
local pipe = "/tmp/godot.pipe"

vim.lsp.start({
    name = "Godot",
    cmd = cmd,
    filetypes = { "gdscript" },
    root_dir = vim.fs.dirname(vim.fs.find({ "project.godot", ".git" }, {
        upward = true,
        path = vim.fs.dirname(vim.api.nvim_buf_get_name(0))
    })[1]),
    on_attach = function(client, bufnr)
        vim.api.nvim_command('echo serverstart("' .. pipe .. '")')
    end
})

Setup using neovim/nvim-lspconfig

If you're using neovim's official nvim-lspconfig, you can omit setting up the lsp server using the naked vim.lsp API and ftplugin. In this case, the following configuration is recommended:

local lspconfig = require("lspconfig")

lspconfig.gdscript.setup({
    cmd = { "godot-wsl-lsp" },
})

WSL mirrored networking mode

If you're using WSL's 'mirrored' networking mode (supported since WSL 2.0.0, you can use the --useMirroredNetworking flag when starting your lsp server:

cmd = { "godot-wsl-lsp", "--useMirroredNetworking" }

Manually specifying what host to connect

If you prefer, you can also specify the host ip address you wish to connect manually:

cmd = { "godot-wsl-lsp", "--host", "1.2.3.4" }
