test_whitespaces - script to check files for errors in whitespaces


test_whitespaces [FILEs or DIRs or both]


      --only_errors     Script will output only errors
      --help            Show this message
      --version         Show version number

Script will work on text files that are specified as the parameters or are situated in the specified diretories.

Script will check if all the rules are followed.

  • Each line ends with "\n" (including the last line)

  • For new lines "\n" is used (not "\r\n")

  • There are no ending spaces on the lines

  • 4 spaces are used instead of tabs

  • No empty lines in the end of file

In case of errors script outputs friendly information what is wrong.

There is also a script `whiter` that can fix all that errors and there is a Perl module Test::Whitespaces that can be used to test your source code.
