Coding Guidelines

Similar to Google C++ Style Guide but with following exceptions:

• No license boilerplate
• Tabs instead of Spaces
• Line length of 120 characters
• #pragma once instead of #include guards

The code should be self-documenting, don't state the obvious! However, this does not make comments superfluous: Since good naming is sometimes not enough, more advanced parts need to be documented, so any operating system developer should be able to easily understand your code.

Naming Convention

• Variables: lowercase with underscore

  char* variable_name;
  

• Constants (and enum values): uppercase with underscore

  const int CONST_VALUE = 42;
  

• Type Names (class/struct/namespace/enum): Capital letter, camel case

  class SomeClassName;
  

• Methods/Functions (C++): start with lowercase letter, then camel case

  void someFunctionName();
  

• extern "C" Functions: lowercase with underscore (like variables).

  void interrupt_handler(int vector);
  

• File Names: lowercase, main type name, underscores only if is a sub type
