Code Style

  • Maximum Line Width is 100 Characters The reason is not about people with low-res screens but rather sticking to 100 columns prevents you from easily nesting more than one level of if statements or other code blocks.
  • Use 4 Space Tabs to Indent With whitespace fillers.
  • No Trailing Whitespace
  • Follow the GNU-Style guidelines. We won't go through all of them here.

Please use the same indentation as other developers. Follow the style used in GNU Midnight Commander:

indent --gnu-style --format-first-column-comments --indent-level4 --brace-indent0 --line-length100 --no-tabs --blank-lines-after-procedures

or in short notation:

indent -gnu -fc1 -i4 -bli0 -nut -bap -l100
