Here some tools are found. They a designed to help our development.

If you use vim text editor, you can use the given vimrc to replace or update something in your ~/.vimrc file. Previously we had some problems with TABs instead of spaces, as well as undesired trailing whitespaces.

The basic is to use expandtabs :set et, which would avoid TABs by expanding it to spaces. To ensure 4 spaces while keeping the indentation in new lines, a it would be :set et ai ts=4 sw=4. The vimrc here does that and also several other useful configuration, like highlighting for the undesired whitespaces.

In any case, to replace all tabs in a file to spaces using vim, just type :ret. For breaking text lines up to textwidth (79 chars in vimrc, following PEP8), type 3gqj, replacing the 3 by the number of lines that makes one single paragraph (before the new line breaking). That's useful for RST files (reStructuredText).

There is also a purge_whitespace.sh script. It fixes the white space issue in all .py and .sh and files of the project. So when adding new files that my not the ok about whitespace, run this script.

cp vimrc ~/.vimrc
./purge_whitespace.sh
