The autopilot has grown beyond being just an autopilot. It's
components, filters and controllers could be used to set property
values based on complex rules and driven from other property values.
That's why I chose to give it the name "property-rule".
This patch allows to define an arbitrary number of property rules under
a/sim/property-rule[n]/path
using the same syntax as autopilot configurations.
- Point the homedir variable to %APPDATA%/flightgear.org. This
enables .fgfsrc in this path for windows users.
- Evaluate the returncode of gethostname() to not strdup() bogus
characters on failure. Also mainly on windows.
Add helper to look for an aircraft branch path in multiple candidate locations.
Update the main subsystems to use the helper, and hence load from any aircraft dir.
Split the former single-file-implementation in xmlauto.?xx into multiple
files and use some OO techniques. Started with documentation to be used
with doxygen.
* AI aircraft distance to user proximity detection works again (lat/lon were inverted).
* The parking uses by the user aircraft is marked as such to prevent it being reused by an AI aicraft
* AI aircraft won't receive permission for pushback until the user aircraft is at a fair distance.
* Add a new command line option: --sound-device=""
This makes OpenAL use the sepcified audio device instead of the default
output device. (Look for playback devices when calling openal-info of alcinfo)
- allow multiple <autopilot> elements within an aircraft. All autopilot live in an individual FGXMLAutopilot subsystem which run within a subsystem group now.
8:: AWOS is available at AWOS locations. (Previously only ATIS was
implemented.)
9:: ATIS phraseology now more nearly conforms to international
standard METAR pattern, and therefore to usual FAA practice.(*)
Items marked with a (*) are fully implemented in the /text/ of the
ATIS message, but the voiced version of the message is degraded by
limitations of the FGFS built-in text-to-speech system.
10:: ATIS now reports sky condition.(*)
11:: ATIS now reports multiple layers of clouds, not just the lowest
layer.(*)
12:: ATIS now takes field elevation into account when calculating
sky condition and ceiling.
13:: ATIS now reports dewpoint.(*)
14:: ATIS now can handle negative quantities (temperature and dewpoint).(*)
15:: ATIS can now report report fractional-mile visibility.(*)
16:: ATIS now uses magnetic (not true) wind directions, as it should.
17:: ATIS generates correct runway number and suffix (nine right,
one one left).
18:: ATIS can be received on nav frequencies, not just comm.
19:: Nothing bad happens if the same ATIS is tuned up on more than
one receiver.
20:: ATIS can be updated at times other than at the top of the hour.
21:: ATIS listens for an "attention" signal, and responds to changes
in the weather by issuing a new ATIS message (somewhat like a
"special observation").
22:: ATIS volume now responds to radio volume setting.
23:: Area-related services (i.e. approach radar) are handled
more-nearly consistently with radio-frequency related services.
24:: ATIS sequence-letter generation has been fixed.
25:: ATIS messages are now in the property tree, so they can be read
e.g. via the http interface.
