fix-whitespace: Fixes whitespace issues

This tool can keep your project and repository clean of trailing whitespace and missing terminal newline.

Usage: fix-whitespace [-h|--help] [-v|--verbose] [--version] [--check] [--config CONFIG] [FILES]

The program does the following to files specified in FILES or in the configuration file fix-whitespace.yaml under the current directory (and its subdirectories):

• Remove trailing whitespace.
• Remove trailing lines containing nothing but whitespace.
• Ensure that the file ends in a newline character.
• Expand tabs to spaces (optionally).

Available options:

• -h --help

  Show this help information.

• -v --verbose

  Show files as they are being checked.

• --version

  Show program's version.

• --config=CONFIG

  Override the project configuration fix-whitespace.yaml.

• --tab=TABSIZE

  Expand tab characters to TABSIZE (default: 8) many spaces. Keep tabs if 0 is given as TABSIZE. (Option available since 0.0.9.)

• --check

  With --check the program does not change any files, it just checks if any files would have been changed. In the latter case, it returns with a non-zero exit code.

For an example configuration file see the one of Agda.
