10To configure LuaLS you can create a `.luarc.json` file in the root of your workspace.
11
12See [LuaLS Settings Documentation](https://luals.github.io/wiki/settings/) for all available configuration options.

14```json
15{
16  "$schema": "https://raw.githubusercontent.com/LuaLS/vscode-lua/master/setting/schema.json",
17  "runtime.version": "Lua 5.4",
18  "diagnostics.severity": {
19    "duplicate-set-field": "Hint"

21  "format.enable": true,
22  "format.defaultConfig": {
23    "indent_style": "space",
24    "indent_size": "4"

32## Formatting
33
34### LuaLS
35
36To enable auto-formatting with your LuaLS, make sure you have `"format.enable": true,` in your .luarc.json add the following to your Zed `settings.json`:
37
38```json
39{
40  "languages": {
41    "Lua": {
42      "format_on_save": "on",
43      "formatter": "language_server"
44    }
45  }
46}
47```
48
49### StyLua
50
51Alternative you can use [StyLua](https://github.com/JohnnyMorganz/StyLua):
52
531. Install [StyLua](https://github.com/JohnnyMorganz/StyLua): `brew install stylua` or `cargo install stylua --features lua52,lua53,lua54,luau,luajit` (feel free to remove any Lua versions you don't need).
542. Add the following to your `settings.json`:
55
56```json
57{
58  "languages": {
59    "Lua": {
60      "format_on_save": "on",
61      "formatter": {
62        "external": {
63          "command": "stylua",
64          "arguments": ["--syntax=Lua54", "-"]
65        }
66      }
67    }
68  }
69}
70```
71
72You can specify various options to StyLua either on the command line above (like `--syntax=Lua54`) or in a `stylua.toml` in your workspace:
73
74```toml
75syntax = "Lua54"
76column_width = 100
77line_endings = "Unix"
78indent_type = "Spaces"
79indent_width = 4
80quote_style = "AutoPreferDouble"
81call_parentheses = "Always"
82collapse_simple_statement = "All"
83
84[sort_requires]
85enabled = true
86```
