You can set up a FlightGear configuration via XML by creating a XML file that loads on to of FlightGear's other settings.
Next to using graphical launchers like FGRun or FGx or parsing console commands to FlightGear's binary, FlightGear's configuration can also be set by means of two .xml files.
defaults.xml and autosave.xml
FlightGear installs with a configuration already set up in a XML file, Template:Base Package Filename. Some of these settings are preserved between FlightGear sessions in another file, autosave.xml
. All settings contained in these two files get parsed by FlightGear while it starts up.
Some of the properties in Template:Base Package Filename have an XML attribute, userarchive
, that automatically add any changes of those properties to autosave.xml
.
we should absolutely stop telling anyone to edit Template:Base Package Filename in FG_ROOT; any documentation or advice which says to should be changes ASAP. [1]
defaults.xml
See defaults.xml for the main article about this subject. |
Template:Base Package Filename is FlightGear's main configuration file and is located within $FG_ROOT.
Using the property-list format it sets up a large number of properties and their values that determines various settings of FlightGear. It more or less contain all settings that can be set. All settings contained within this file get parsed by FlightGear while it starts up.
autosave.xml
autosave.xml
is a child of preferences.xml
in user space that contains the properties with an userarchive="y"
attribute. Location depends on the operating system used:
OS | Path |
---|---|
Windows Vista/7/8 | C:\Users\{Your username}\AppData\Roaming\flightgear.org\
|
Windows XP | C:\Documents and Settings\{Your username}\Application Data\flightgear.org\
|
Linux/OS X | ~/.fgfs
|
If not present, it is generated upon launching FGFS with the options set in its parent file Preferences.xml.
Any changes you do within FlightGear's user interface are saved into autosave.xml
, so a manual edit is, in most cases, not necessary. The next time you launch FGFS, the settings stored in autosave.xml
will be used.
Adding your own settings
Rather than modifying preferences.xml
or autosave.xml
you should create your own configuration file using the same format and load it using the --config
command-line parameter. You are not limited only to use properties from those files, but can use any properties from the property tree. You can also add entirely new properties if that is needed.
When you use the --config
option to load your own configuration, it will be loaded into FlightGear just as preferences.xml
and autosave.xml
, but your configuration will be used instead. To use your own configuration add this command-line parameter either in .fgfsrc
or when you start FlightGear:
--config=/home/<user name>/.fgfs/<my-preferences>.xml
The reason to why you should not modify preferences.xml
or autosave.xml
is that the modifications can cause problems with your FlightGear installation and, unless you manually make a copy of them, they will be lost when you upgrade or uninstall FlightGear. In addition, using a configuration file from one version of FlightGear with another version may not work too well either.
