* Fixed the initial conditions settings (geodetic altitude is now correctly computed).
* FGLGear reports the time at which it detected a violent ground hit (aka crash)
* Doc update of the kinematic component
* TurboProp code cleanup with the removal of lots of obsolete/no-op members.
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.
* Fixed the trim on ground algorithm. Now JSBSim aircrafts should no longer be 'dropped' on the runway at start.
* Removed a correction on the propeller induced velocity that was giving erratic results when the aircraft aero velocity is very small.
* Various source comments updates.
Tolerate the case where a URL matching the exact FG version is
not found; lookup a generic URL, in the hope it supports our
version (additional changes will make this more likely)
The precipitation branch of the OSG scene graph is now centrally managed by the
scenery manager rather the precipitation manager itself. The scene graph
initialisation from the constructor has also been shifted into the new
FGPrecipitationMgr::sceneGraphSetup() function.
As the scenery manager's init() function is called twice on start up, two OSG
scene graph roots would be created. A number of scene graph branches would be
initalised on the first root, but then be lost as the second is created. This
fixes the precipitation branch, for example.
- The first place where indentation is fixed was really misleading, at
least.
- The added comment "'line' may end with an \r character [...]" just
clarifies something that has been there for ages, to avoid people
falling into the trap.
- don't duplicate the line buffer (array of char as well as
std::string), it is not useful here;
- don't corrupt (truncate) input lines longer than 2048 bytes: there is
no such limitation in the apt.dat v1000 format spec;
- fix comments handling: the apt.dat v1000 format spec states they must
start with *two* '#' characters.
- The first two lines of apt.dat have their own special syntax -> handle
them separately. Before this commit, the test "is the first character
an 'I' or an 'A'?" was done for *every* line of apt.dat, while it is
only relevant for the first one.
- Fix counting of the current line number (it was most of the time
0-based so far, which could be seen in error messages, because the
second line of apt.dat was absorbed without going through the common
code path where lines are normally read at the top of the while loop).
With this commit, line numbers in apt.dat are consistently counted
starting from 1.
Remove useless code before parsing the "row code" (terminology from the
apt.dat v1000 spec). The row code is parsed with atoi(), which will
automatically stop at the first space found if it saw at least one
digit, thus there is no need to replace it with '\0', AFAICS.
One could replace the existing atoi() call with things that do better
checking, but my tests showed that would be a bit slower, so I let it
this way (tried with std::istringstream and strtol()).
When using live weather fetch, the QNH should be obtained from
environment/metar/pressure-inhg.
See: http://sourceforge.net/p/flightgear/mailman/message/35037125
Add new method getQnhInHg to ATISInformationProvider and its implementations
to avoid rounding errors converting from hPa back to inches in ATIS reports.
The CurrentWeatherATISInformationProvider (used when live weather fetch is
not in use) continues to use the property environment/pressure-sea-level-inhg.
This produces the incorrect QNH at airports significantly above sea level
but this needs fixing elsewhere to calculate the correct QNH.
- Add section tag to support inclusion of ATIS fragments.
- Add visibility, QNH and cloud tokens to support new ATIS formats.
- Add support for starts-with, ends-with and contains comparisons in
conditionals, including negated versions.
- Strip and convert case in comparisons.
- Speak VRB wind direction as "variable".
- Speak zeroes in fractional part of QNH inHg.
- Force US voice in US, Canada and Pacific; UK voice in UK.

If no aircraft is selected in the launcher, the routine
AircraftItemModel::indexOfAircraftURI is called with an empty QUri,
triggering a warning in the terminal.
This commit removes such warning by ignoring QUris with empty schemes
(the routine still returns an invalid index).
Prior to this change, it was only possible to compare the values of tokens
to each other for use in conditionals, e.g. landing and departing runway.
This change allows comparison of a token to a text value, e.g. to compare
wind speed to zero.
osg::texture2D changes GL_UNPACK_ROW_LENGTH, which fntLoadTXF is not
prepared to deal with. Reset the value back to 0 before loading +
caching TXF fonts on the PLIB side.
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 --metar option has no effect unless --disable-real-weather-fetch is
also passed. This often makes users believe that --metar doesn't work.
Change the implementation for --metar so that it automatically implies
--disable-real-weather-fetch.
After removing /Models from FGData loading of shared models from
within a scenery model failed because the ResourceManager did not know
about additional scenery paths.
- Only clear the OSG ‘pose as standalone’ flag when we really show
a dialog, as opposed to when we /might/ show.
Tested:
- Qt build using launcher
- No Qt build
- Qt build but launcher not requested
This patch may introduce an occasional crash on exit again, because it effectively undoes commit [a972df]. I'll try to find a better fix for that later on.
- work in progress, goal is to make copyToCurrent and most of
the bind/unbind logic sink into each specific View, avoiding all the
null pointer checks in view manager.
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.
This follows from http://thread.gmane.org/gmane.games.flightgear.devel/78650 and
resolves the sign bug https://sourceforge.net/p/flightgear/codetickets/1778/ .
Combined with a matching change to FGData, this changes the HUD formats from the
current set of 3 (note that the text in brackets is not shown in the HUD
preferences PUI dialog, but is show here for reference):
0) Decimal degrees (37.618890N -122.375000W)
1) Degrees, minutes (37*37.133N -122*22.500W)
2) Degrees, minutes, seconds (37*37 08.0 N -122*22 30.0 W)
to (here the text in brackets will be shown in the PUI dialog):
0) DDD format (37.618890N 122.375000W)
1) DMM format (37*37.133'N 122*22.500'W)
2) DMS format (37*37'08.0"N 122*22'30.0"W)
3) Signed DDD format (37.618890 -122.375000)
4) Signed DMM format (37*37.133' -122*22.500')
5) Signed DMS format (37*37'08.0" -122*22'30.0")
6) Zero padded DDD (51.477500N 000.461389W)
7) Zero padded DMM (51*28.650'N 000*27.683'W)
8) Zero padded DMS (51*28'39.0"N 000*27'41.0"W)
9) Trinity House Navigation (51* 28'.650N 000* 27'.683W)
Being able to list arbitrary directories is a privacy violation;
existing in-fgdata uses of this are all permitted paths
(i.e. not Terrasync; FileSelector doesn't use it)
- Use setlocale() to ensure consistent handling of locales and
string handling irrespective of whether or not QCoreApplication
is invoked. Forces a the C locale for numerics and collation,
since many pieces of FG assume this.
I didn’t know about this feature when doing the original CMake files,
we can use this to target header-file includes more precisely.
(Probably more cases exist that can be changed from global to target-
specific includes)
- add a button to the main dialog, explaining how to adjust the
fg-root path via the GUI
- tweak the GUI flow to support explicitly changing the path even
when the default path is acceptable.
- because uiuc_warning_error always called exit(-1), it can be marked
no return, so Clang realises that when it’s used in the ‘else’
side of a parsing test, uninitialised variables in the enclosing
call site are safe.
(Requires Simgear update to define SG_NO_RETURN helper)
- when dynamics shuts down the ATC controllers, they clear their
traffic vectors (destroying the records), but we didn’t notify
the AI aircraft of this. Ensure the controller is cleared so
the AI aircraft shutdown doesn’t crash.
Under some conditions on my system
aircraft_paths.begin() was equal to scenery_paths.end()
This resulted in neither of them being added to read_allowed_paths
followed by failure to load Nasal scripts from the aircraft directory.
This might happen, if scenery_paths gets allocated just before aircraft_paths
in memory.
Better loop across the desired lists instead of using fancy tricks with
the iterator.
- sim-speed-up (a/A keys) offsets warp correctly. This means at 4x speed
up the warp will increase by 3 seconds for one elapsed real second.
In practice this means simulation elements timed using sim ‘current time’
will be correctly synchronised with those using simulated elapsed time.
(AI traffic being a prime example of this)
- warp-delta (t/T keys) is independent of frame rate, and works when
paused. The warp-delta values in the keybindings / GUI dialog
will need to be updated since warp-delta in now seconds-per-second,
as opposed to seconds-per-frame.
- change launcher to examine the scenery paths and hence load
ground-net files for airports to populate parking data.
- refactor ground-net XML parsing to use FGGroundNetwork only, not
AirportDynamics.
- change parenting of GroundNetwork to Airport, since it contains
immutable data now.
- when no runway use preferences XML exists, be smarter about using
available runways. Makes the common case of using two parallel
runways for arrivals and departures work, greatly improving AI
traffic behaviour.
- consistent with pause (freeze), /sim/speed-up is now applied to the
dt value for all subsystems, not just the FDM and some instruments.
For example AI traffic can now be sped-up or slowed down.
- requires both an FGData and Simgear update.
- when switching views, force an update() to ensure view position
is valid. Otherwise various subsystems such as AI traffic and the
tile manager see a request for a 0,0 location.
- when switching to model view, we still generate a 0,0
location initially - to be fixed.
Avoid intermittent race conditions on shutdown when the OSG
pager/Db thread is running. Ensure the OSG threads are stopped before
we start tearing down any scene graph nodes.
- 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
- ATC functions move to GroundController, which layers above
remaining GroundNetwork functionality
- dynamics owns both the groundNetwork and the ground controller.
This is for the FGProperties::getLongitudeString() and
FGProperties::getLatitudeString() functions. The previous algorithm was to
round the degrees up by the smallest fraction required to prevent a round up to
60 minutes or seconds, and then round down the final minutes or seconds by the
same fraction. The new algorithm is to detect if the final minute or seconds
will be rounded to 60 by the string formatting and, if so, the higher unit
(degrees or minutes) is incremented by one, and the lower unit decremented by
60.
As QApplication only stores a reference to argc, it may crash if
the argc passed to it goes out of scope. (One way to trigger this
is to pass an invalid --fg-root, triggering an initApp call from
Options::setupRoot.) Copy argc to prevent this.
Drop fgNormalizePath, use realpath() only
As this makes it accept relative paths, always use the returned
(absolute) version for the actual file operation to avoid check-to-use
races, or where this is not possible (NasalSGPath) explicitly reject
relative paths
Fix: do_save is a write, not a read
* Before setting /sim/aircraft-dir from the --aircraft-dir option,
canonicalize its value with SGPath::realpath() as is already done in
FGGlobals::append_aircraft_path() for the paths given with --fg-aircraft
or via the FG_AIRCRAFT environment variable.
* This fixes a bug when --aircraft-dir is used, due to the fact that
fgValidatePath() canonicalizes its 'path' argument before matching it
against the allowed patterns, and therefore will not validate paths
under the directory specified with --aircraft-dir if this directory has
been given in a non-canonical form by the user (e.g., containing at
least one symlink component).
* This fix does not lower security: the path which is canonicalized has
been explicitely given by the user. This operation is already done for
all paths specified with --fg-aircraft or via the FG_AIRCRAFT
environment variable, via Options::initPaths() which calls
FGGlobals::append_aircraft_paths().
* To reproduce the bug, create a symlink (e.g., /tmp/aircrafts) to a
directory suitable for --fg-aircraft, then run:
fgfs ... --fg-aircraft=/tmp/aircrafts \
--aircraft-dir=/tmp/aircrafts/SenecaII --aircraft=SenecaII
This will trigger many failures such as:
loadxml: reading '/tmp/aircrafts/SenecaII/Dialogs/registration.xml'
denied (unauthorized directory - authorization no longer follows
symlinks; to authorize reading additional directories, add them to
--fg-aircraft)
(from do_load_xml_to_proptree() in flightgear/src/Main/fg_commands.cxx)
I have also tested this with the ec130b4 and the 777-200ER. Same
problem, same fix.
* If one has the same aircraft in several aircraft directories,
FlightGear should not mix resources from the various aircraft
directories. For instance, if one starts FG with:
--fg-aircraft=/my/personal/dir:/path/to/fgaddon/Aircraft
and one has in /my/personal/dir/ec130 a clone of the upstream
developer repo, FlightGear should use either the upstream version from
/my/personal/dir/ec130 or the FGAddon version from
/path/to/fgaddon/Aircraft/ec130, but not some strange, untested hybrid
of both.
* This commit makes sure that when the looked-up resource starts with
Aircraft/<ac>, where <ac> is the current aircraft name [last component
of aircraftDir = fgGetString("/sim/aircraft-dir")], then
AircraftResourceProvider::resolve() doesn't search other aircraft
directories if the resource isn't found under 'aircraftDir'.
* To reproduce the bug before this commit, you may add the following
code (there is nothing specific about the SenecaII here, it's just the
aircraft I used for testing):
var file_path = resolvepath("Aircraft/SenecaII/flo-test");
if (file_path != "")
gui.popupTip("flo-test found", 2);
else
gui.popupTip("flo-test not found", 2);
in a keyboard binding for the SenecaII (for instance; you may use the
F11 binding that otherwise only prints a short message). You should
add this to the SenecaII/SenecaII-base.xml file *that will be loaded
by FlightGear*, let's say the one under /my/personal/dir in the
example above (beware of the <path-cache> in autosave_X_Y.xml). Then,
by creating or removing a file named "flo-test" in the SenecaII
subdirectory of other aircraft dirs (for instance,
/path/to/fgaddon/Aircraft in the example above), you can see that the
behavior of the loaded aircraft is influenced by the contents of
unrelated versions of the same aircraft that might be present in other
aircraft dirs (e.g., loaded /my/personal/dir/SenecaII influenced by
/path/to/fgaddon/Aircraft/SenecaII).
* Aircrafts loading resources using paths relative to the current
aircraft directory (e.g., with 'resolvepath("flo-test")') are not
affected by this kind of problem, because this scheme is handled by
CurrentAircraftDirProvider, which does not exhibit this bug.
negative latitude/longitude coordinates resulted in negative WEST/
SOUTH coordinates for the default format 0 (zero).
This should be now fixed so that
+12.3 gets formatted as 12.3N/E
-12.3 gets formatted as 12.3S/W
https://bugs.debian.org/780867
This messy approach is to minimise changes during freeze; for 3.7,
I plan to make realpath() handle non-existent files as "realpath
they would have if created now" and get rid of fgNormalizePath
This is insecure because it always (not just on Windows) converts
\ to / before .. checking. Either use the path it returns (as in
f_open()) or use an SGPath (where this conversion is already done)
Only a minor problem because the affected functions are limited to
the .sav file type
and using speed up time to allow a fine displayed predicted position
when time accelerated (no more jumping planes accelerated using the mp patch)
tell me if it's not the good pace to do such things ;)

Richard J. Senior:
Without this commit, unknown top-level tags in instrumentation.xml are treated
as errors and the rest of the file is not processed.
Users running Flightgear versions prior to 3.2 have experienced problems with
the comm-radio tags after downloading updated versions of aircraft from FGADDON.
Instrumentation listed after the unrecognized comm-radio tags is not processed
for these users and is inactive in the cockpit.
This commit changes the instrumentation build method so that unrecognized tags
are treated as warnings. This won't help users running older versions but
protects against the same problems occurring if new tags are added to
instrumentation in the future.
updates to properties used to be

* The Pitot angle can now be tweaked with the <pitot_angle> tag in the <metrics> block.
* The refuel rate is now configurable with the <refuel-rate> tag in the <propulsion> block.
* Fixed C++11 compliance. JSBSim can now be compiled with a C++11 compiler.
* Avoid a spurious mass report to be issued when resetting.
* Fixed the moments computation. Previously they were computed with the previous time step CG position.
* Fixed a bug where the CG update was delayed to the next time step when point masses location were modified via the FCS.
While mostly harmless since you're exiting anyway, it's an annoying

Syd Adams:
I've added an update to dme.cxx /dme.hxx.
It adds a formatted KDI572-574/nm , min and kt string properties meant
for text animations for these instruments.Existing instruments will funtion
as usual, no breaks. The purpose here is to eliminate yet another nasal
workaround which usually needs to repeat some of what the code already does.
The 3 properties are empty when the dme is off (no need to check for power),
dashes when powered up but no source , out of range ,etc.
The are formatted to the KDI-572/573/574 limits ...
0-99.9/100-389 for distance to station,
0-99 minutes for time to station,
groundspeed 0-999 kt.
The old Mac launcher doesn’t work on Yosemite, add a tiny
Qt-based launcher inside the main process (no need to fork /

Will be merged for 3.4, hopefully with no impact on other
platforms.
Usually, in a real cockpit, altimeter shows hPa setting as an integer number and InHg setting is limited to 2 decimals
In aviation we don't need higher numeric precision

don't start the traffic manager before the FDM is initialized
The FDM needs the scenery loaded and will wait for all PagedLOD Nodes
to appear if they are close (less than 1000m) to our initial position.
That's required for scenery models but not for AI traffic.
Unfortunately we can’t drop loaded ones, since the in-memory structures don’t have ref-counting, and we don’t
know what AI plans may be referencing them.
This patch enables AIModels to use the size on the screen for LOD instead
of distance from eye point.
With /sim/rendering/static-lod/ai-range-mode-pixel set to true
/sim/rendering/static-lod/ai-detailed now contains the minimum size of the
model on the screen to be displayed. Values of 10-50 seem to make some sense.
To avoid trouble when running multiple instances on one machine, disable

Since the consensus seems to be that the precipitation clipping issue is with the panel code, attached is my proposed update for the precipitation system in SG and FG
* without corresponding control structures in FGData it falls back to default, except I have fixed an inconsistency in freezing behavior - previously rain changed suddenly to snow when the temperature dropped below zero, but the reverse transition was dragged out and gave odd visible motion with the wind as snow gradually changed back to rain with the particle speed not well defined. Now both transitions are sudden. And I see no more particles flow against the wind
* with
<!-- definitions for the detailed precipitation manager -->
<precipitation-control>
<rain-droplet-size type="float" userarchive="n">0.015</rain-droplet-size>
<snow-flake-size type="float" userarchive="n">0.03</snow-flake-size>
<detailed-precipitation type="bool" userarchive="n">false</detailed-precipitation>
<illumination type="float" userarchive="n">1.0</illumination>
<clip-distance type="float" userarchive="n">5.0</clip-distance>
</precipitation-control>
added to Environment/environment.xml, the new system allows to switch more detailed management on. This provides
* explicit setting of rain droplet size and snow flake size by the weather system
* automatic sqrt(r) scaling of the vertical speed of raindrops
* automatic transition to snow when freezing for small droplets but hail for large droplet sizes (looks like snow, but has different particle dynamics)
* an illumination scaling factor to dim the precipitating based on the light we have in the scene (I still need to devise a property rule to set this automatically)
The clip distance is also exposed now and considered at startup of the system - might be useful for e.g. airships when the gas bag provides rain cover (?) or to be simply off for open airplanes
- Introduce a new LOD: ai-interior
- Load a <model> with <usage>interior</usage> on-demand
- Avoid to load the cockpit of players in MP
- Default LOD is 0.0 - 50.0 meters
Adds new option --load-tape=foobar to load a flight recorder
tape from the command line. Loads foobar.fgtape from the
directory specified in /sim/replay/tape-directory and starts
replay.
the static system has an optional "tau" parameter to
define the rate at which the output value changes.
Setting this value to zero now disables the filter.
This prevents wrong airspeed indications on rapid
altitude changes. No functional changes if tau has
other-than-zero values (e.g. the default systems).
write the vertical flight path to /orientation/path-deg
zero means level flight, positive angles climb
Also use SGD_DEGREES_TO_RADIANS (and vice versa) for double computations
instead of the float constants
Also allow events on desktop group if no window is receiving
events. Currently it is not possible to prevent events handled
by the desktop group to further propagate (eg. to normal
control input).
- /sim/aircraft can be set to package ID, including qualified

Change the drag coefficient for fuselages along the Y and Z axes
(i.e. perpendicular to the fuselage's main axis) to use a fixed
value of 0.5. (The value can still be adjusted using the fuselage's
"cy" and "cz" XML attributes.)
For the Y-axis and Z-axis drag on fuselages, YASim originally used
a drag coefficient equal to:
(solver drag factor) * (fuselage length/width ratio)
This value turns out to be way too small for well-streamlined
aircraft, even those with long, narrow fuselages, and especially
so for those with short, stubby fuselages. Such fuselages are
streamlined in the X direction, but not along Y or Z.
0.5 is only a ballpark estimate, but it's reasonably close for the
common case of a fairly long fuselage with a round cross section. For
flat-sided fuselages, a larger value should be used, up to a maximum
of 2 for a slab-sided block. For short fuselages, the value should be
reduced to account for end effects. The fuselage's "cy" and "cz" XML
attributes can be modified to make such adjustments.
This fix won't affect straight flight much, but it should have a strong
impact on some maneuvers. For example, it will make slips more
effective and may make knife-edge flight easier on aerobatic aircraft
which should be capable of it.
Only aircraft which specify version="YASIM_VERSION_32" or newer are
affected.
This commit is in prepartion for the following commit, which is a bug fix for
Issue 1463 (YASim underestimates off-axis forces on fuselages).
Previously the solver would adjust the drag factor for all of an Airplane's
non-Wing Surfaces in one pass, with no attempt to distinguish Fuselage Surfaces
from the Surfaces for Gear and Weights. This makes it difficult to modify how
fuselage drag is calculated while leaving unaffected the drag for landing gear
and external weights.
Now the solver adjusts the drag for an Airplane's fuselages, landing gear, and
external weights in three separate passes. To do this, each Fuselage now has a
list of its Surfaces. The fuselage pass simply iterates through the list of
Fuselages, running through each Fuselage's list of Surfaces.
The Airplane's list of non-Wing Surfaces, "_surfs", is no longer used here, but
there may still be uses of it elsewhere.
This patch enables spoken words without the need for external
festival using the existing FGVoiceMgr subsystem and the
properties under /sim/sound/voices
To hear the generated voices, set /sim/sound/voices/enabled=true
at startup
- use FLITEVoiceSynthesizer if a voice has <festival>false</festival>
- use FLITEVoiceSynthesizer if the festival server is unreachable
- decouple FGFLITEVoice from FGVoiceThread
Correct handling of fuselage's "midpoint" XML attribute so that the midpoint's
location matches the point assumed by all aircraft developers and YASim docs.
This means the fuselage won't be generated "back-to-front".
Also correct the variation of diameter for tapered fuselages so that both ends
of the fuselage narrow from the midpoint to the endpoints.
Before this, one end was narrowing from the endpoint to the midpoint, the
opposite of what was expected.
These changes affect both weight distribution and the distribution of lateral
aerodynamic forces.
- Add a very simple line-of-sight propagation model for the radio

By default, if the system version exists and can be used,
then it will be used. Otherwise, the local version will be used
Original patch by Saikrishna Arcot via
https://gitorious.org/fg/flightgear/merge_requests/1582
slightly modified
/sim/sound/voice-synthesizer/volume to set the volume of the generated wav (in dB)
/sim/sound/voice-synthesizer/keep-scratch-file do not remove the scratch file if true
user attribute "version" of the airplane element of the YASim config file
to define the version this config uses.
Example:
<airplane mass="1344" version="YASIM_VERSION_CURRENT">
Initially, the following can be used:
YASIM_VERSION_ORIGINAL - The original version of YASim as implemented up to
FlightGear 3.0.0
YASIM_VERSION_32 - The version of YASim implemented in FlightGear 3.2.x
(and the development version 3.1.x)
YASIM_VERSION_CURRENT - The current and latest version of YASim.
naBindFunction doesn't save the function code to the global
hash, so pass an explicit context to various 'call' overloads so
the function can't be GC-ed in between parsing and calling.

Fixes confusing startup behaviour with malformed args, when
an argument accidentally contains a space (e.g. a park-pos or
protocol desc). In this case we treat the parts after the space as an XML config file name. When we can't find this file, we
completely abandon options setup, which causes many downstream
errors.
Change the behaviour so we warn in this case, but carry on with normal startup.
add special attribute 'ts' to a JSON property reflecting
/sim/time/elapsed-sec
always add timestamp for listener properties
add timestamp for json requests if req param t=y is set
- fix corrupted ident on Mac (libc++ issue)
- don't clear scratch when activating DTO mode
- use the real navaid/airport for the waypt where possible
- expose active waypt name
* mongoose updated to 5.3
* first stab at implementing websockets, here a property change listener
websocket. This websocket is at ws://yourhost:yourport/PropertyListener
see FGDATA/Docs/gui/radio.html for an example
to run a fg-command with args, POST run.cgi?value=my-command
and post the args node as JSON content like this:
{
name: '',
children: [
{
name: 'property',
index: 0,
value: 'first-value is here'
},
{
name: 'property',
index: 1,
value: 'first-value is here'
}
]
}
or whatever arguments the requested command takes
This is too destructive for many established things, so revert it.
Instead, make the FDM shell save /fdm state on postinit(), and
restore it on re-init (which reposition invokes).
- Not compiled by default, nor hooked up to anything yet.
- Both libraries licensed under modified BSD license.
- Added top-level CMake file for both, to create a plain static
library for each.
add request parameter 'i' and 'd'
if i=y, indent the output to make it human readable
if i is missing or anything else, send the output unformatted to save bandwith
'd' defines recursion depth with a default of 1 to show the requested node
and the immediate childs (if it has any)
call /json/?i=y&d=999 for a complete property tree backup (use with caution!)
Also set the encoding to UTF-8 as required per RFC 4627
Adds $FG_ROOT/Aircraft/Generic/JSBSim/{Engines,Systems} to the JSBSim
engines and system search paths. Internally JSBSim already searches
$aircraft_dir/Engines and $aircraft_dir/Systems.
A file in $aircraft_dir/{Engines,Systems} have higher priority than one
in the shared directories.
Introduces delay-sec and release-delay-sec properties. The former is how
long to wait to run the binding(s) after pressing the button, the latter
is how long to wait after releasing the button. interval-sec now
specifies the delay before a repeat event occurs.
- Calculate line of sight distance instead of distance over
ground
- Do a nav cache update if carrier_nav.dat.gz timestamp has
changed
- Allow comments in carrier_nav.dat.gz
- "Fix" range calculations (still does not take terrain/weather
and other influences into account)
Added the fallback for realweather fetch disabled, creating
ATIS from present weather
Fixed some formatting errors, mainly missing spaces
Some code cleanup
Calls to updateValues can cause nested calls invalidating
the char* passed as argument, if retrieved from a
SGPropertyNode.
Probably SGPropertyNode should also be modified to return
a std::string instead of a pointer to an internal buffer.
- use old-style reset as the basis for a lightweight 'reposition' command. This does not restore state, or reset
time management, but does reset the FDM and re-finalize position.
- Current 3D clouds rendering does not use the alpha buffer,
so don't request one at launch, since it consumes valuable GPU memory.
- Remove any references to alpha testing or alpha func in the renderer setup.
- restores functionality of 'draw-otw' property
- adds new /sim/rendering/draw-mask branch to allow control
over rendering each branch inside FGScenery
* 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)
As suggested by a long-standing enhancement idea,
extend getprop/setprop to accept multiple args,
including integer arguments. This removes the need
for string concatenation (and hence, allocation)
on the Nasal side.
Patch by Nicholas 'Philosopher' Scheel
- check for invalid tiles / buckets, which occurs at the poles
- use .sibling() method to offset
- no longer need to store view lat/lon in the manager.
- Support interface properties as with JSBSim for easy reuse
and parametrization of autopilot components.
- Add property-root property to allow changing property root
for all relative paths. This allows easy use of multiple
instances of the same autopilot component at the same time
by specifiying different property root nodes.
