      "--" can be used to terminate flag options and force all following
      arguments to be treated as positional options

The program will attempt to automatically use the current directory's .lua-format file if no config file is passed in the command line. If none is found, it will try to locate a .lua-format file in a parent directory recursively. On Linux it will use $XDG_CONFIG_HOME/luaformatter/config.yaml if .lua-format does not exist. In case there's no file, it will fallback to the default configuration. The program will give the top priority to the configuration values given in the command-line, then to the configuration files and finally to the hard-coded default values.

Style configure file

Configuration parameters not specified fallback to their default values.

Disable formatting for a line or block

Sometimes it may be useful to disable automatic formatting. This is done be putting the code between LuaFormatter off and LuaFormatter on tags:

-- LuaFormatter off
matrix = {
   {1, 0, 0, 0},
   {1, 1, 0, 0},
   {1, 1, 1, 0},
   {1, 1, 1, 1}
}
-- LuaFormatter on

Limitations

  • Do not work when source file contains syntax error
  • Do not support 'Format selection'
