FGRUN prop value with space

[sleemanj]

Ok, probably a stupid question, but using fgrun, how does one set a property which has a space in the value, eg set /sim/sound/device-name to "Alsa Software on Default" for example.

Hi,

open Advanced > Properties on the last page of the launcher (before clicking Run) and create a new property with /sim/sound/device-name="Alsa Software on Default".

Enjoy!

That does not work unfortunately, neither quotes nor spaces are properly escaped when they get passed to the command line.

Try going back to the very first page (hit "Prev" from the aircraft selection screen) and just tack it on to the "executable" line...??

Hm, you mean the spaces are replaced with _ and " with ' when FG is loaded? I believe our property tree does not allow for ", as strings always are encapsed with '...'. The closes you could get is /sim/sound/device-name=Alsa Software on Default" which will result in: /sim/sound/device-name='Alsa Software on Default'

@MDTerp : That doesn't work either, fgrun tries to execute the entire thing as the executable, rather than an executable with an argument.

@gijs: No I mean the spaces are not replaced with anything, they remain spaces, but they are not escaped, so FG interpets the command line argument as something like...

--prop=/sim/sound/device-name=Alsa
Software
on
Default

ie it see 4 arguments, and promptly dies.

FGrun does not seem to have any way to provide a space within a property, properly. This actually also applies for example to the multiplayer call sign, put in a space and it breaks, where there should be no issue.

Must be a bug in FGrun.

Must be a bug in FGrun.

But, to confirm, you are able to enter the desired command line manually, and FGFS will start with that audio device enabled?

[sleemanj]

Yes, manually running the command line

fgfs --prop:/sim/sound/device-name=Alsa\ Software\ on\ Default

works correctly.

Setting the property in FGRun does not (even if I insert backslashes to manually escape).
