Re: [plexil-support] Plexil Viewer not working correctly in 4.5.0RC2?

[Dalal, M. (ARC-TI)[S. INC] <mic...@na...>]

Hi Martin,

Thanks for your message to plexil-support and your interest in PLEXIL.

I was able to reproduce the problems you reported with the Plexil Viewer.  The entry I have just added and committed in plexil-4/CAVEATS sumarizes the situation:

 * May 3, 2019.  For a while now, the Plexil Viewer is not in a good working
   state.  It has not been actively supported in years, and has a variety of
   problems.  PLEXIL is still in strong use, in its command line form.

The example plan will run fine without the viewer:

  plexiltest -p DriveToTarget.plx -s scripts/DriveToTarget.psx
    
You can get detailed information about execution state by entering the desired flags in your Debug.cfg file -- see the section on executing PLEXIL plans on Sourceforge.  This is how we have been running PLEXIL and debugging plans.  At the moment we don't have the budget and staff needed to work on the PLEXIL viewer.  Hopefully we will at some point, but in the mean time you are encouraged to debug/improve the Viewer yourself if you are so inclined.  We would welcome any fixes or enhancements to it from the PLEXIL community.  We hope that PLEXIL otherwise meets your needs.

Best,
Mike
