    • Use “:%retab” in cmd mode to replace all existing Tabs
  • one tab
• Write comments appropriately
  • Comments for functional block but not for code line
  • Comment lines before the described code block
  • One blank line before comment lines to separate it from other logics
• Maximum text width is 80 columns in a line, with very few exceptions
• Deal with “()” and “{}” correctly
  • Add 1 blank space when with reserved word: for (), if ()
  • Directly connect when with function: functionA()
