Previously, the Nasal files in fgdata/Nasal/*.nas were loaded in
file-name order. This created a particular problem file files
beginning with "a" which might want to use props.nas.
This adds support for an ordered list of files to be defined
in the property tree that will be loaded before the rest of the
Nasal files.
Overhaul how transitions are stored in FlightPlan XML, and how
they’re exposed to Nasal. Simplify the Nasal access by making
‘sid_trans’ and ‘star_trans’ writeable.
Extend the unit-tests a lot to cover this, both from C++ and also
from Nasal
As part of this, overhaul the ownership of FlightPlan delegate
factories, to make it safer (use ref-counting of the factories,
and allow the factory to customise delegate clean-up behaviour)
Where the plan does not contain departure / arrival WPs, fire the
corresponding delegate methods after load, to run the selection logic.
Also, add a ‘loaded’ delegate callback, to give delegates a chance to
perform validation and fix-up after all flight-plan loads.
Only the in-sim version works for now, the test-suite mode is not
implemented yet. Also the test API will evolve, but should stay close
to what CppUnit defines.
Run a test file by specifying a path to nasal-test : examples will be
added to FGData shortly.
To support FMS which delete ‘past’ waypoints, add some helpers:
- waypoints can be flagged as hidden, this property is exposed to Nasal
- currentWP() accepts an offset parameter, allowing FlightPlan indexing
to treat the current WP as index 0
- a ‘numRemainingWaypoints()’ function on flightPlan in Nasal, again
to range how many waypoints are left, starting from the current WP
Add some basic tests of these new features to the route-manager tests.
Replace the default io.stat with one which uses our validator, and
uses SGPath to call _wstat on Windows. This does mean we return less
information in the stat() result, but it seems nothing actually uses
the result apart from checking if the file exists.
Still not complete, but now we set the command line args to be UTF-8 on
Windows, we can strip out more of the ‘local 8-bit’ places (which
screw up, generally).
- Fix Leg ownership to avoid segfaults when deleting them via Nasal
- Modify FP save/load code so restrictions and holds are correctly
saved and restored
Extend the tests to cover these cases.
