Summary of 'Clean code' by Robert C. Martin

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.


General rules

  1. Follow standard conventions.
  2. Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
  3. Boy scout rule. Leave the campground cleaner than you found it.
  4. Always find root cause. Always look for the root cause of a problem.

Design rules

function notifyme {
  LAST_EXIT_CODE=$?
  CMD=$(fc -ln -1)
  osascript -e 'on run argv
  tell application "System Events"
    set frontApp to name of first application process whose frontmost is true
 if frontApp is not "Terminal" then
