Sections
languages
This section specifies which commands should run for which language.
Each entry is the name of the language as the key, and a list of format commands to run in sequence as the value. Each format command needs to read from stdin and write to stdout.
Usage
With arguments
You can run cbfmt
on files and or directories by passing them as arguments.
cbfmt [OPTIONS] [file/dir/glob]...
The default behaviour checks formatting for all files that were passed as arguments. If all files are formatted correctly, it exits with status code 0, otherwise it exits with status code 1.
When a directory is passed as an argument, cbfmt
will recursively run on all files in that directory which have a valid parser and are not ignored by git.
With stdin
If no arguments are specified, cbfmt
will read from stdin and write the format result to stdout.
cbfmt [OPTIONS] < [file]
Without arguments and stdin
If there are no arguments and nothing is written to stdin, cbfmt
will print the help text and exit.
Options
These are the most important options. To see all options, please run cbfmt --help
-c|--check
check Works the same as the default behaviour, but only prints the path to files that fail.
-w|--write
write Writes the format result back into the files.
-p|--parser
parser Specifies which parser to use. This is inferred from the file ending when possible.
