notes on "Clean Code - Formatting" chapter

• Formatting is important
• A source code file should read like a newspaper article.
  • Name should be simple and explanatory.
  • Top parts of the file should provide high-level concepts.
  • The lower == the more detailed information.
• Blank lines help in identification of separate concepts.
• Pieces of code which are related should be kept close in source code.
• Instance variables should live at the top of the class file.
• Local variables should be declared as close as possible to the place of usage.
• Code which is executed from a function, should be below that function.
• Lines should be at most 120 columns wide. (Uncle’s Bob personal preference)
• Preserve indentation of blocks.

Set team formatting rules and make everyone use them!
