View source for Hangar catalog

The default '''hangar catalog''', <code>catalog.xml</code>, is used by the in-sim Aircraft Center to list all the aircraft of the [[FGAddon|official FGAddon FlightGear hangar]].  [[Flightgear hangars#Third party sites|3rd party hangars]] can also provide a catalog URL via their own <code>catalog.xml</code> file.

== Catalog generation ==
The <code>catalog.xml</code> file can be generated using the {{fgmeta source|path=catalog/update-catalog.py|text=update-catalog.py}} Python script.  Alongside the script is the <code>fgaddon-catalog/</code> directory, which is the configuration files used to generate the catalog for the [[FGAddon]] official hangar.  To generate the FGAddon catalog, as an example, type:

<syntaxhighlight lang="sh">
./update-catalog.py fgaddon-catalog
</syntaxhighlight>

The idea is to create a subdirectory tree for each catalog.  This subdirectory can have any name, and it contains the config and administrative files for maintaining the catalog.  The config file inside the catalog directory will need to be adjusted for each new hangar.  The script builds the content locally which then needs to be uploaded to an appropriate place on a server.
