* make --enable-fpe work on Linux and MSVC
* standardise the code paths for different platforms
* add an argument finding helper to Options
(This is a basic cleanup, contributions from people with
more experience in this area are welcome)
- no dependency on libJpeg or Simgear
- no duplicate rendering of the scene (uses a draw callback)
- supports other image types, eg PNG
- threaded so doesn't block the main loop ever
This makes the behaviour when FGRun (or other GUI launchers)
send bad options much more explicable. Non Windows/Mac systems
get an SG_ALERT on the console as before.
This was previously done only if Terrasync was on, but this made
it impossible to use the GUI dialog to turn it on for the first
time in a fresh install
Write PID file to FG_HOME, use this to detect multiple launches.
When this situation is detected, set a marker property and place various
objects into read-only mode, such as the NavCache and TerraSync.
PID file is created using open+unlink semantics on POSIX, and
DELETE_ON_CLOSE on Windows, so it will be removed when fgfs exits,
even if killed or crashes.
This allows us to display a platform-native dialog for problems
which occur early in startup (before we can show a PUI/Canvas dialog).
In particular this improves feedback where FG_HOME, FG_DATA or
aircraft selection is wrong, all of which happen very early in startup.
Requesting 16-bit is probably doing more harm than good on modern
hardware. Command line switch to change works as before.
Also update the default window size, although this is actually
set by preferences.xml
- default to SUBSYSTEM:WINDOWS (we can still AllocConsole if needed)
- add --console option to get a console on Windows
- ensure --show-aircraft and --help modes show the console automatically.
- restore-defaults kills the nav cache, terra-sync cache
- new ignore-autosave option bypasses autosave.xml and leaves it
untouched (does not over-write on exit)
Replace many lingering calls to exit() from the code,
replacing most with exception throws, which can be
caught by the existing mechanisms.
Update the option-parsing code to return an explicit
value indicating what to do (e.g., exit status to return
to the shell).
Many light aircraft include GPS loggers capable of recording the flight
path using IGC records. Lots of third party utilities are available to
analyze, process and convert igc files.
Usage: "fgfs --igc=file,out,1,OutputFile.igc"
- Enable the terrasync persistent cache
- Ensure terraysync scenery dirs exist before NavCache init, so the paths are stable
- Notify TerraSync on reposition, so we sync the full 3x3 set of tiles.
If you want a scenario in a particular session of the sim, ask for
it on the command line / config files, or enable in the GUI.
Note if you had previously 'sticky' scenarios in your autosave.xml, you
will still get them until you clean your autosave, or disable them in
the GUI.
"speed-up" can now also be used for slow-motion (i.e. 0.5 / 0.25 / ...)
or fractional speeds (3.141...). This was already working for instruments
(for replay) before, now it's also considered by FDM simulation.
For (future) easier testing of the sim, support a mode where only explicitly named config / option files are loaded, instead of the default ones. (Including, for example, preferences.xml). This currently produces a non-functional sim, but will soon be more useful :)
No behaviour should change unless you try the new option.
so package builders don't need local patches.
Also, instead of hardcoded firefox, use "xdg-open" or "sensible-browser"
launchers on Linux, to auto-detect user's preferred browser.
Override with cmake switch -DWEB_BROWSER=...
(Not affecting Mac/Win which are hard-coded anyway).
