default.cfg5

Overview

default.cfg is the configuration file for chocolate-doom(6). The configuration options stored in the file are the same as those stored in the original DOS Vanilla Doom. Extra Chocolate Doom-specific options are stored in a separate configuration file, chocolate-doom.cfg.

default.cfg is normally stored in the user's home directory, as ~/.local/share/chocolate-doom/default.cfg. The path can be overridden using the XDG_DATA_HOME environment variable (see the XDG Base Directory Specification).

The chocolate-doom-setup(6) tool provides a simple to use front-end for editing default.cfg.

File format

The file is a plain-text file, consisting of a list of configuration options and their values, separated by whitespace. Each option is stored on a separate line. Options have different types; an option may have either an integer, floating point or string value. If the option is of a string type, the value is surrounded by quotes (").

For example:

Invalid lines or comments in the file will be ignored, but it is advisable not to put them in the file; the file is rewritten from scratch every time the game exits, so any invalid lines or comments will be lost.

Some options are used for keyboard key bindings; these are stored as integer values containing the keyboard scan code of the key to be bound to. Boolean values are also stored as integers, with a value of zero usually indicating "false" and a non-zero value indicating "true".
