.luarc.json can't work with lua-language-server

[mrxiaozhuox]

I have installed lua-language-server and tried to create a Lua config file, but it's not working for the LSP server.

helix --healt lua

Configured language server: lua-language-server
Binary for language server: /opt/homebrew/bin/lua-language-server
Configured debug adapter: None
Highlight queries: ✓
Textobject queries: ✓
Indent queries: ✓

In case anyone sees this unanswered question and feels discouraged, I am currently using helix 24.7 and adding a .luarc.json file works for me here. As an example, here is what my file looks like. If you use it as an example, you can see the keys I used and adjust them to your liking.

{
  "workspace.library": [
    "/path/to/library"
  ],
  "runtime.version": "Lua 5.2",
  "hint.enable": true
}

I'm using this to develop scripts that operate within the context of a lua library plugin for a game. It's cool, works fine here for me for now. Good luck!

i'm running helix 25.01.1 and .luarc.json doesn't work for me either. It's working for neovim though so i'm not sure what is the cause. I'm trying to point workspace.library to a folder with type annotations and nvim can read .luarc and discover that folder without issue

{
	"$schema": "https://raw.githubusercontent.com/LuaLS/vscode-lua/master/setting/schema.json",
	"workspace.library": ["./wezterm", "../../lib/wezterm-types/types"],
	"runtime.version": "Lua 5.3",
	"hint.enable": true,
	"format.defaultConfig": {
		"indent_style": "space",
		"indent_size": "3",
		"insert_final_newline": "true",
		"space_around_table_field_list": "true",
		"align_continuous_assign_statement": "false"
	}
}

both should also be using the same lua-language-server

update: helix is now showing types ONLY when i have the files themselves open in the buffer, so i guess helix can't source the paths in workspace.library ? this is still pretty unusable because

1. I still have to open the type files which defeat the purpose
2. If the types are split into multiple files then i have to open all those files in the buffer

I'm having a hard time reproducing this error @mnpqraven.

I tried using a similar config and was able to immediately have type information available.

lua-types-helix.mov

Is there something I'm missing on the difference between our setups?

@TurtleP I will add a patch to enable formatting by default to lua. In the meantime, you can add this to your languages.toml to get autoformatting

[[language]]
name = "lua"
injection-regex = "lua"
scope = "source.lua"
file-types = ["lua", "rockspec"]
shebangs = ["lua", "luajit"]
roots = [".luarc.json", ".luacheckrc", ".stylua.toml", "selene.toml", ".git"]
comment-token = "--"
block-comment-tokens = { start = "--[[", end = "--]]" }
indent = { tab-width = 2, unit = "  " }
auto-format = true
language-servers = [ "lua-language-server" ]

Be aware that per the Lua Language Server docs, configuration for indentation should be done at the editor level. For helix, this means either changing the setting in your languages.toml for global configuration or in a .editorconfig file for local configuration.

hi @CalebLarsen , i've managed to finally get it working. I had to put the .luarc.json at the root of the workspace otherwise it wouldn't work. My previous workspace was kinda like this.

.git # root
.config/
  wezterm/
    .luarc.json
    other_lua_files.lua
lib/
  lua_library/

now stylua formatting is not working with the default configuration, whew...

edit: i fixed it right after posting this (i guess you just need to complain more), needed to have this extra flag

# languages.toml
formatter = { command = "stylua", args = ["--search-parent-directories", "-"] }
