11
12See [LuaLS Settings Documentation](https://luals.github.io/wiki/settings/) for all available configuration options.

30## Formatting
31
32### LuaLS
33
34To 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`:
35
36```json
37{
38 "languages": {
39 "Lua": {
40 "format_on_save": "on",
41 "formatter": "language_server"
42 }
43 }
44}
45```
46
47### StyLua
48
49Alternative you can use [StyLua](https://github.com/JohnnyMorganz/StyLua):
50
511. 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).
522. Add the following to your `settings.json`:
53
54```json
55{
56 "languages": {
57 "Lua": {
58 "format_on_save": "on",
59 "formatter": {
60 "external": {
61 "command": "stylua",
62 "arguments": [
63 "--syntax=Lua54",
64 "--respect-ignores",
65 "--stdin-filepath",
66 "{buffer_path}",
67 "-"
68 ]
69 }
70 }
71 }
72 }
73}
74```
75
76You can specify various options to StyLua either on the command line above (like `--syntax=Lua54`) or in a `stylua.toml` in your workspace:
77
78```toml
79syntax = "Lua54"
80column_width = 100
81line_endings = "Unix"
82indent_type = "Spaces"
83indent_width = 4
84quote_style = "AutoPreferDouble"
85call_parentheses = "Always"
86collapse_simple_statement = "All"
87
88[sort_requires]
89enabled = true
90```
