at the end of the day, the main bottleneck is not the language/interpreter supported by FlightGear, but the way it is integrated - and the legacy SGSubsystem/Mgr approach is simply not suitable for large-scale scripting, certainly not the kind of scripting that would definitely be boosted by supporting a more mainstream language like Lua or Python. | |||
Thus, there are things that need to be addressed first, which is why it makes sense to review Richard's postings in this thread, and explore using Torsten's mongoose/Phi approach, i.e. remote properties and async fgcommands to use those as the foundation for a scripting subsystem that runs outside the fgfs main loop. | |||

There is work that lies ahead that would benefit FGPythonSys and FGNasalSys at the same time - such as a strong IPC mechanism, like HLA, or even just Emesary via remote properties (asynchronous remote properties and fgcommands, as per Torsten's mongoose/Phi work) - Torsten basically proved that you don't need to use HLA to come up with async modules that can interface with the rest of FG - if this, his, approach were to be formalied, standardized and extened, many other subsystems could be using this, none of which would be facing the challenges that Nasal/Python are currently facing (or in fact any other SGSubsystem not using SGthread, too).<ref>{{cite web | There is work that lies ahead that would benefit FGPythonSys and FGNasalSys at the same time - such as a strong IPC mechanism, like HLA, or even just Emesary via remote properties (asynchronous remote properties and fgcommands, as per Torsten's mongoose/Phi work) - Torsten basically proved that you don't need to use HLA to come up with async modules that can interface with the rest of FG - if this, his, approach were to be formalied, standardized and extened, many other subsystems could be using this, none of which would be facing the challenges that Nasal/Python are currently facing (or in fact any other SGSubsystem not using SGthread, too).<ref>{{cite web | ||
