stylua configuration in MegaLinter	How to use stylua (configure, ignore files, ignore errors, help & version documentations) to analyze LUA files

stylua

StyLua is an opinionated code formatter for Lua that automatically formats Lua code to enforce consistent style. It removes the need for debates about formatting by providing sensible defaults while still allowing some configuration.

Key Features:

Opinionated formatting with sensible defaults for consistent Lua code style
Automatic indentation and spacing management
Line break optimization for improved code readability
Configurable options via stylua.toml for project-specific needs
Lua 5.1-5.4 support covering all modern Lua versions
LuaJIT compatibility for Just-In-Time compiled Lua code
Roblox Luau support with specialized formatting rules
Fast performance for formatting large codebases quickly
Ignore comments to exclude specific code sections from formatting
Range formatting to format only selected portions of files

Disable stylua by adding LUA_STYLUA in DISABLE_LINTERS variable

Variable	Description	Default value
LUA_STYLUA_ARGUMENTS	User custom arguments to add in linter CLI call Ex: `-s --foo "bar"`

LUA_STYLUA_FILTER_REGEX_INCLUDE	Custom regex including filter Ex: `(src\|lib)`	Include every file
LUA_STYLUA_FILTER_REGEX_EXCLUDE	Custom regex excluding filter Ex: `(test\|examples)`	Exclude no file
LUA_STYLUA_CLI_LINT_MODE	Override default CLI lint mode - `file`: Calls the linter for each file - `project`: Call the linter from the root of the project	`file`
LUA_STYLUA_FILE_EXTENSIONS	Allowed file extensions. `"*"` matches any extension, `""` matches empty extension. Empty list excludes all files Ex: `[".py", ""]`	`[".lua"]`
LUA_STYLUA_FILE_NAMES_REGEX	File name regex filters. Regular expression list for filtering files by their base names using regex full match. Empty list includes all files Ex: `["Dockerfile(-.+)?", "Jenkinsfile"]`	Include every file

LUA_STYLUA_POST_COMMANDS	List of bash commands to run after the linter	None
LUA_STYLUA_UNSECURED_ENV_VARIABLES	List of env variables explicitly not filtered before calling LUA_STYLUA and its pre/post commands	None
LUA_STYLUA_CONFIG_FILE	stylua configuration file name Use `LINTER_DEFAULT` to let the linter find it	`stylua.toml`
LUA_STYLUA_RULES_PATH	Path where to find linter configuration file	Workspace folder, then MegaLinter default rules
LUA_STYLUA_DISABLE_ERRORS	Run linter but consider errors as warnings	`false`
LUA_STYLUA_DISABLE_ERRORS_IF_LESS_THAN	Maximum number of errors allowed	`0`
LUA_STYLUA_CLI_EXECUTABLE	Override CLI executable	`['stylua']`
