Allow modules to define an unload callback, and also drive
the 'loaded' property to false, to give modules the ability to clean
up when being unloaded. This makes reloading work without
errors for Canvas.
Additionaally, add some special code when creating the
Canvas module, to ensure the C++ defined pieces are loaded :
fortunately Canvas is the only module which needs this.
Move the fgValidatePath() code and the two associated static variables
'read_allowed_paths' and 'write_allowed_paths' to SimGear.
fgValidatePath() is now known as SGPath::validate(). This requires
SimGear commit e002a481f481709263a.
(Disabled by a CMake option)
This builds equivalent C++ objects to what the PUI dialogs build, with
properties exposed to Nasal. Peer objects are created by Nasal callbacks,
which can implement the various dialog functions needed to keep
compatibility, especially the ‘update’ and ‘apply’ hooks.
This is by Lars Toenning <dev@ltoenning.de>, Roman Ludwicki <romek21@op.pl> and
SDeAstis <salvatore.deastis@gmail.com>, in 2021 Hackathon.
Also cope with removal of SGPropertyNode::getName() - use getNameString()
instead.
This is to avoid console/log spam from jetways.nas in particular,
which uses loadxml to probe for file existence, every 10 seconds. But
in general it seems useful to have this potentially be quiet, since
there is a result code.
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.
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.
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).
Use a new SGPropertyNode flag, LISTENER_SAFE, to white-list properties
where we do correctly fire listeners, and test this flag when listening
from Nasal, to avoid the warning.
