WoW:Console

The console is fundamental to the entire engine. It determines how the Graphics API is initialized, controls how configurations are set, and allows many features to be toggled or adjusted using Commands without having to quit the game.

Commands

A command is a whitespace-less string associated with various attributes:

• A function:

The function accepts the name of the command as a string, as well as an optional argument string. For example, running the following command:

RUN commandname "with argument"

will dispatch a handler function:

int32 handler(const char* command, const char* argument) {
  print(command);  // "commandname"
  print(argument); // "with argument"
  return 1; // boolean, 1 means the command succeeded
}

• A category number

Determines the placement of the command when displayed using help command.

• Help text

This is left empty in most cases. It describes how to use the command, and is shown by the help command.

The Command may or may not have a help message, and it may have a Category number that controls its placement when displayed by the 

Categories

Every Command or CVar belongs to a category number.

WTF Files

Configurations are persisted across game sessions using .WTF (Warcraft Text File?) files.

Each WTF is a text file, containing only Commands separated by a \r\n, or CRLF sequence.

Differently named WTFs may interpret specific commands only (such as Config.WTF, which rejects every line that does not begin with the set command).

Config.WTF is loaded by the client immediately at startup, and saved during graceful shutdown. It contains every non-default CVar set by the client.

Usage

To enable the console, the client must be specially launched using the -console command-line argument.

To use the console, simply press the tilde (~) key at the top-left of your keyboard to show the draggable console screen.

Screen

The screen is customizable using several CVars.
