Code style

The code style we follow in the EasyBuild code repository is mainly dictated by the Python standard PEP8.

Highlighted PEP8 code style rules:

  • use 4 spaces for indentation, do not use tabs
    for example, use :set tabstop 4 and :set expandtab in Vim
  • indent items in a list at an extra 4 spaces
    nested lists can be indented at the same indentation as the first item in the list if it is on the first line, closing brackets must match visual indentation
  • use optional underscores, not camelCase, for variable, function and method names (i.e. poll.get_unique_voters(), not poll.getUniqueVoters)
  • use InitialCaps for class names
  • in docstrings, don’t use “action words”

The only (major) exception to PEP8 is our preference for longer line lengths: line lengths must be limited to 120 characters, and should by preference be shorter than 100 characters (as opposed to the 80-character limit in PEP8).
