When an explicit aircraft-dir is set, check this location before
checking installed packages. This allows setting —aircraft and
-aircraft-dir to correctly take precedence over a package.
New methods Addon::createStorageDir() and Addon::getStoragePath() with
corresponding Nasal bindings in the addons.Addon ghost:
createStorageDir() method (returns the dir, doesn't fail if it already
exists)
storagePath read-only attribute to get the dir
The directory reserved for each add-on is
$FG_HOME/Export/Addons/ADDON_ID, but please use the above methods (or
the corresponding C++ ones) to avoid hardcoding such paths in your code.
Also create directory $FG_HOME/Export/Addons in fgInitConfig() as a way
of reserving the namespace, in order to prevent future failures in case
someone would have the strange idea to create it as a file...
This commit adds C++ classes for add-on management, most notably
AddonManager, Addon and AddonVersion. The AddonManager is used to
register add-ons. It relies on an std::map<std::string, AddonRef> to
hold the metadata of each registered add-on (keys of the std::map are
add-on identifiers, and AddonRef is currently SGSharedPtr<Addon>).
Accessor methods are available for:
- retrieving the list of registered or loaded add-ons (terminology
explained in $FG_ROOT/Docs/README.add-ons);
- checking if a particular add-on has already been registered or
loaded;
- for each add-on, obtaining an Addon instance which can be queried
for its name, id, version, base path, the minimum and maximum
FlightGear versions it requires, its base node in the Property Tree,
its order in the load sequence, short and long description strings,
home page, etc.
The most important metadata is made accessible in the Property Tree
under /addons/by-id/<addon-id> and the property
/addons/by-id/<addon-id>/loaded can be checked or listened to, in
order to determine when a particular add-on is loaded. There is also a
Nasal interface to access add-on metadata in a convenient way.
In order to provide this metadata, each add-on must from now on have in
its base directory a file called 'addon-metadata.xml'.
All this is documented in much more detail in
$FG_ROOT/Docs/README.add-ons.

Call fgInitAllowedPaths() right after Options::processOptions() (which,
among other things, determines $FG_ROOT and processes
--allow-nasal-read). This way, fgInitAllowedPaths() can be used in much
more code, such as when initializing subsystems.
This adds console and message-box warnings, based upon aircraft
declaring the minimum FG version they support. A follow-up commit
will extend the launcher UI to warn the user about this in a nicer
way.
This is a headless mode, designed to be invoked from an installer, not
used directly by users. It doesn’t touch the ‘normal’ installation, but
rather removes the other files FG typically creates or downloads.
${CMAKE_SOURCE_DIR}/src/EmbeddedResources/FlightGear-resources.xml
(currently empty) is automatically "compiled" into
${CMAKE_BINARY_DIR}/src/EmbeddedResources/FlightGear-resources.[ch]xx by
fgrcc inside the build directory. These files are incorporated into the
FlightGear build (FlightGear-resources.cxx is linked into FlightGear).
When the XML embedded resource declaration file added here,
FlightGear-resources.xml, is compiled, fgrcc is passed the
--root=${CMAKE_SOURCE_DIR} option, so that files referred to in
FlightGear-resources.xml are looked up relatively to the root directory
of the FlightGear repository. One could use a second XML embedded
resource declaration file compiled with a different --root option to
grab files from FGData, for instance. I would name such a file
FGData-resources.xml to be consistent with the current naming scheme.
Note: this --root option applies to the paths of real files. Don't
confuse it with the 'prefix' attribute of <qresource> elements
inside XML resource declaration files (such as
FlightGear-resources.xml), which applies to the virtual path of
each resource defined beneath.
The commands in src/Main/CMakeLists.txt ensure that
FlightGear-resources.xml is recompiled with fgrcc whenever it is
changed, and obviously also when FlightGear-resources.cxx or
FlightGear-resources.hxx is missing. However, CMake doesn't know how to
parse fgrcc XML resource declaration files, therefore when a resource is
modified but the XML file it is declared in is not (here,
FlightGear-resources.xml), you have to trigger yourself a recompilation
of the XML resource declaration file to see the new resource contents
inside FlightGear. The easiest ways to do so are:
- either update the timestamp of the XML resource declaration file;
- or remove one or both of the generated files
(FlightGear-resources.cxx and FlightGear-resources.hxx here).
The EmbeddedResourceManager is created in fgMainInit() just after
Options::processOptions() set the language that was either requested by
the user or obtained from the system (locales). Resources from
FlightGear-resources.cxx are added to it, after which
EmbeddedResourceManager::selectLocale() is called with the user's
preferred locale (obtained with FGLocale::getPreferredLanguage()).
Upon reset (fgStartNewReset()), EmbeddedResourceManager::selectLocale()
is called in a similar way after Options::processOptions(), however in
this case the EmbeddedResourceManager instance doesn't have to be
recreated.
- Rename fatalMessageBox() to fatalMessageBoxWithoutExit(). This should
prevent the kind of bug that prompted this set of changes: someone
calling fatalMessageBox(), assuming the program would stop at that
point, whereas in reality it did not.
- Add new function fatalMessageBoxThenExit(). This is not vital of
course, but allows one to spare one line here and there and to apply
the DRY principle for such fatal exits.
- Replace every existing call to fatalMessageBox() with one or the other
of the two new functions. Improve formatting along the way. This
fixes a few bugs of the kind explained above.
Make a single Cmake value to expose the build type to code, and use
this to default a run-time ‘developer-mode’ property, which can be
over-ridden from the command line.
Use this to drive the different warning levels. Policies subject to
review, especially whether nightly builds should default to
developer mode or not.
Uses TTF fonts, and displays more information textually including
the application version and current aircraft.
Also rename FGRenderer::splashinit to preinit, as was suggested
a long time ago.
This change is the logical counterpart of SimGear's change from commit
79f869a7f32910197be72b21f6489fbbba02c836 that moved the following files
from simgear/misc to simgear/io/iostreams:
gzcontainerfile.cxx
gzcontainerfile.hxx
gzfstream.cxx (formerly zfstream.cxx)
gzfstream.hxx (formerly zfstream.hxx)
sgstream.cxx
sgstream.hxx
sgstream_test.cxx
Requires FGData commit: 0565eaab10a5d466cd485766b17d1870936a0a57
(which actually renames the file).
Also disables the preferences-load command since I don’t believe it
would actually be safe to reload the defaults without doing a simulator
reset (aircraft -set.xml values would be overwritten, for example)
This is likely to fix the problem preventing startup on Windows when the
username contains non-ASCII characters (cf.
<https://forum.flightgear.org/viewtopic.php?f=22&t=31320>). Thanks to
Headhunter76 for the useful report and to wkitty42 for doing the liaison
officer. ;-)
I can't actually test this, because I don't have Windows. Windows users
should report whether this works for them.
It is not needed anymore to hardcode the number of lines of
$FG_ROOT/Airports/apt.dat.gz. The new method, which relies on
SGPath::sizeInBytes() and sg_gzifstream::approxOffset(), works as well
for the other dat files.
Add a new NavCache rebuild phase, REBUILD_READING_APT_DAT_FILES, since
the process is now made of two parts.
Rename NavDataCachePrivate::getDatFilesPaths() to
NavDataCachePrivate::findDatFiles(), because it now returns a
DatFilesGroupInfo (new struct) instead of a PathList. For the same
reason, rename NavDataCachePrivate::aptDatPaths to
NavDataCachePrivate::aptDatFilesInfo. Adapt signatures, etc.
This requires up-to-date SimGear and FGData.
Remove uses of .str(), .c_str() and some other methods of SGPath.
Pass SGPath directly where possible, or explicitly convert to the
appropriate 8-bit encoding.
When set on the command line, will be used for aircraft packages. When
set in the Qt launcher, will also be used for aircraft downloads at
all times.
When changing the path in the launcher, the set of aircraft catalogs
is refresh automatically. Note the default catalog may need to be
re-installed.
The problem was that the change to make FGScenery a standard subsystem caused
the particle OSG group to no longer be inserted into the scene graph. The
solution was to convert the particle group to be set up as a standard branch of
the scene graph, alongside the terrain, models, aircraft, and interior branches.
The particle system is now set up as part of the init() subsystem function call,
so it is compatible with the new subsystem design.
- remove some global headers from AI headers, to avoid pollution
- change how ATC owns the ‘player’ FGAIAircraft so reset works
- ensure AIAircraft controllers are cleared on unbind for reset
