Document your code


The document you are reading now was generated using Doxygen. It follows in the tradition of literal programming, the goal of which is to keep documentation in the source code, when practical. This way, the documentation will not be outdated or unmaintained.

Commenting interfaces

Concise comments are prefered, as long as the explanation is correct, is not open to interpretation and does not assume extensive knowledge of other parts of the system.

By interface, we mean all content of a header file which is available from a C++ source file, and could result in compile errors if removed. When you comment a header file, you need to take care of a few, minor things in order to produce readable documentation using Doxygen. The basic guidelines for this project are:


/** Takes care of displaying the map and game-data on the screen.
* The display is divided into two main sections: the game area,
* which displays the tiles of the game board, and units on them,
* and the side bar, which appears on the right hand side.
* The side bar display is divided into three sections.
class display
ADDON_SP_CAMPAIGN, /**< Single-player campaign. */
ADDON_SP_SCENARIO, /**< Single-player scenario. */
ADDON_MP_CAMPAIGN, /**< Multiplayer campaign. */
ADDON_MP_SCENARIO, /**< Multiplayer scenario. */


/** @param a an integer dividend
* @param b an integer divisor, which must not be zero
* @returns a / b
* @pre b != 0
* @post divide' = a / b
* @throws std::runtime_error
* @todo this has not been peer reviewed yet
int divide(int a, int b)
return a / b;
