The property tree FGFS uses to expose the it's innards to external applications. It is well suited for describing hierarchically organized structures, such as In the case of FGFS we defined the tags you need to configure things. It looks a lot like HTML, except you get to define your own tags. In case you were wondering, XML stands for eXtensible Markup Language. Keyboard.xml $FG_ROOT XML property list system wide Joystick.xml $FG_ROOT XML property list system wide System.fgfsrc $FG_ROOT command line options system wide fgfsrc ~/ command line options single user The order of precedence for options is thus: Storing alternate keyboard or joystick bindings can be done in a variety of ways. Joystick buttons and keyboard events starts to blur. I will cover joysticks first and save the keyboard stuff for later.įGInput treats things in a generic enough way that the line between Version 0.7.9 added a compiled decision tree allowing for conditionals Keyboard command bindings as well as joysticks.

The code that does this is known as FGInput and is used to configure Version 0.7.7 saw an expanded role for the property manager and theĪddition of a 'command manager' that allows for binding of events to commands. Which facilitated being able to set the parameters for the joystick at runtime. You had to edit the source code and recompile.įortunately, around about v0.7.5 a 'property manager' was implemented, The default channel assignments, or wanted different key bindings, Thanks to David Megginson, who aside from actually implementing FGFS XMLįeatures, lets me rip off his descriptions of how stuff works so I can lookĮarlier versions of FGFS had assignments of joystick axis/buttonsĪnd key bindings hard coded. Is written from the perspective a Linux user, but the information presented It assumes a working joystick present on your system.
