Gedit plugin highlighting whitespace at the end of lines. Very useful when editing files in projects with strict PEP8/Pylint rules.
- Close all open Gedit windows.
- Copy the .py and the .plugin to the Gedit plugin directory. This is typically /usr/lib/gedit/plugins.
- Start Gedit and enable the plugin ("EOLSpace") from the Plugins-tab of Edit->Preferences.
If you completed the installation above successfully there should now be an option called "Run EOLSpace check" on the Tools menu. Clicking it should result in all trailing whitespace on each line getting a nice highlight effect.
