In preparation for caching the groundnet in the NavCache, make taxi-nodes and parkings inherit from FGPositioned. As part of this, make them heap (as opposed to value) classes, disable their copy-constructors, remove many mutating operations, and give them real constructors.
In advance of converting the Map and NavDisplay to use the canvas, expose the full route-path vector for each flight plan leg, as a vector on the leg. Use leg.path() to get this.
E.g.:
var fp = flightplan();
for (var i=0; i<fp.getPlanSize(); i += 1)
{
var leg = fp.getWP(i);
debug.dump(leg.path());
}
Cache the parsed navigation and airport data in a binary file to reduce
startup times and memory consumption (since only referenced FGPositioned
elements are held in memory).
Data will be reimported when the mod-time of any input file is changed.
If a global file is changed (nav.dat, awy.dat, apt.dat, etc), the cache
will be completely rebuilt, which takes approximately 30 seconds on
moderate hardware. (Future work may reduce this).
- Add platform independent clipboard layer for Nasal access
to clipboard (thanks to Hooray for basic code)
- Add Windows clipboard access
- Add partial X11 clipboard access (only reading from clipboard)
- Add fallback clipboard for application internal clipboard if
platform not supported
- Add some helper functions to FGNasalSys
This code is non-functional, but contains most of the stubs to show what's required to add property get/set access, convert to from ghost & C++ types, and manage ownership. Element derived classes & inheritance (e.g., methods on image/path/map elements) will follow, along with some actual functionality!
The routing behaviour now happens entirely in Nasal,
using a delegate, and can be over-ridden or disable
by aircraft authors. Default behaviour should be
unchanged.
Convert the route-manager to use a flight-plan internally, and expose
flightplan, leg and procedure data to Nasal. Move the Level-D parser
into its own file.
Replace SG_GENERAL by more specific log classes in many places.
Allow "," to separate logging classes (using "|" is odd on the
command-line).
Also add new option to make logging more useful for developers.
You can use:
--log-level=debug --log-class=environment
to only get environment debug messages, or
--log-level=debug --log-class=sound,ai
to only get debug messages related to the sound or AI subsystem.
