Re: [plexil-support] Viewing running process in Plexil viewer opened from different terminal window?

Hi Catherine,

I don't believe that what you're attempting is possible.  The Plexil application communicates with the viewer over a socket connection that, I believe, needs to be established when the Plexil application starts.

But I'm curious why you want to run Plexil and its viewer in separate terminals.  Do you know about the '-v' option, which starts and connects the viewer with the executive?  E.g.

  plexilexec -v -p plan.plx

The '-b' (blocking) option adds interactive control -- otherwise the plan will start running immediately.

It sounds like this is what you want.

Thanks for your interest in PLEXIL, and let us know if you have more questions.

Best,
Mike
