Code style common rule

• The most important thing about coding style is to keep your source consistent.
• Add head comments. Follow information is needed:
  • License
  • Brief description
  • Author
  • Version (Optional)
• Tab/blank space indention: Using once method and keep consistent for the component
  • 4 spaces
    • Add “set expandtab tabstop=4 shiftwidth=4” to your .vimrc
    • 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()
  • Two {} Styles, choose one and keep it, but not mix:

Style 1:
If (XXXXX) {
    XXXX
}

Style 2:
If (XXXXX)
{
    XXXX
}

• Naming
  • xxxx_yyyy_zzzz
  • xxxxYyyyZzzz
  • Choose one and keep it, but not mix
  • CamelCase is discouraged. The exception is if the code is heavily tied to some library which uses such notation
• Pre-release test
  • Memory Usage Check Tool: Valgrind
  • Static Code Check Tool: K7
  • Checkpatch.pl
