fix-whitespace: Fixes whitespace issues

Hackage version fix-whitespace on Stackage Nightly Stackage LTS version Build status Haskell-CI

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

Usage: fix-whitespace [-h|--help] [-v|--verbose] [-V|--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. Since 0.1: Display location of detected whitespace violations.

  • -V --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.
