opa fmt [path [...]] [flags]
Format Rego source files.
The 'fmt' command takes a Rego source file and outputs a reformatted version. If no file path is provided - this tool will use stdin. The format of the output is not defined specifically; whatever this tool outputs is considered correct format (with the exception of bugs).
If the '-w' option is supplied, the 'fmt' command with overwrite the source file instead of printing to stdout.
If the '-d' option is supplied, the 'fmt' command will output a diff between the original and formatted source.
If the '-l' option is supplied, the 'fmt' command will output the names of files that would change if formatted. The '-l' option will suppress any other output to stdout from the 'fmt' command.
-d, --diff[=false] only display a diff of the changes
-h, --help[=false] help for fmt
-l, --list[=false] list all files who would change when formatted
-w, --write[=false] overwrite the original source file
