Coding Conventions

  • Indent with tabs (4 spaces) but use spaces for continuation line alignment
  • Allman brackets
    • No brackets around one line conditional statements
  • Padding space after parenthesis headers (if, do, while, for, switch)
  • Align pointer and reference operator to the variable or function name
  • inline keyword always before virtual and static
  • Mark an override method with the override specifier and remove virtual
  • Access specifiers order: public, protected, private
    • One half indent for access specifiers (2 spaces)
  • Declarations order: typedefs and enums, data members, constructors, destructors, methods
    • Friends defined in the private section of a class, after everything else
  • One space padding around operators
  • Use of the explicit keyword all the times it makes sense

Naming Conventions

  • Pascal case for classes, enumerations, typedefs and constants
  • Camel case for variables, functions and parameters
  • All upper case for enumerators in an enumeration

Documenting Conventions

  • Put Doxygen brief descriptions in header files and additional documentation in implementation ones
  • Use Qt style for Doxygen detailed descriptions (/*! */) and end them with a period
