Re: [plexil-support] Question on Plexil adapter interface

[Fry, C. R. {C. (ARC-TI)[S. G. T. I. (S. Inc.)] <chu...@na...>]

If the purpose of your code is to exercise the adapter, a shared dummy CommandHandleVariable will work fine.

Within the Exec, the ack variable is part of the CommandNode. The purpose of the ack variable is to allow nodes to wait on a change of execution state for the command itself.

Chuck,

Thanks for the quick response.

Yes, I can pass the command through C++ to build the ExpressionId, but I wasn’t sure how best/easiest to build it and exactly what data it needed to have inside. You mention that it can be a shared dummy – does that mean it does not have to have any relationship to the specific command that was requested to execute?

Thanks for your help,

Subject: Re: [plexil-support] Question on Plexil adapter interface

I'm not quite sure how you'd construct an ExpressionId from C. Can you go through a small C++ shim library?

ExpressionId is a typedef for Id<Expression>. The Id<T> template is a smart pointer. The default constructor builds  a null smart pointer. This can be used for the dest argument.

The ack argument expects an Id for a CommandHandleVariable. This has to be a real variable instance, but it can be a shared dummy.

Hello,

I have a C function that calls the Plexil Adapter interface to execute commands in the Plexil Engine using the following Adapter method:

The documentation says that the "dest" argument is optional but the "ack" argument must be specified.
How do I create these from C and what values are they supposed to contain?

[plexil-support] Checking Plexil plan state from another Plexil plan?

[plexil-support] Running a plan that calls another plan that calls the original plan...is this possible?

[Catherine S. <Cat...@ti...>]

Hello,
            I'm translating some code into Plexil and here's the situation, albeit simplified:

PlanA (the "master plan")
PlanB
PlanC, which may call PlanA

PlanA needs to call PlanB and PlanC. I tried setting this up to run in the Plexil Executive like so:

Plexilexec -v -b -p plans/PlanA.plx  -library plans/PlanA.plx -library plans/PlanB.plx -library plans/PlanC.plx

This causes the system to hang. I assume this is because it is going in an infinite loop of checking library nodes of PlanA, then when it gets to PlanC, it needs to check the library nodes of PlanA again, and then so on and so forth. If I leave the "-library plans/PlanA.plx" part off, I get an error that the library node for PlanA is not found.

Is there a way to get this situation to work, or is this just not possible? Thanks.

Catherine

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

I see.  If you can make the needed settings in the production app, the following are possible.

1.  A large variety of plan execution status and debugging information can be printed in the shell in which the app runs, if you place a Debug.cfg file in the directory from which Plexil is started, and have the appropriate flags in the file.  Here's the reference on this feature:

http://sourceforge.net/apps/mediawiki/plexil/index.php?title=PLEXIL_Executive#Output_and_the_Debug_Configuration_File

This can provide all the information you'd get in the Plexil Viewer, albeit in a raw form.

2. The Temporal Viewer gives a Gantt style view of the plan's execution, and since its interface is file-based, you can start it outside the application, and even see intermediate results.  See the documentation in:

http://sourceforge.net/apps/mediawiki/plexil/index.php?title=Viewing_Plan_Execution#Temporal_Plan_Viewer

And of course you can use Unix and other tools (e.g. 'top') for system measurements as the plan runs (memory, cpu, etc).

Unfortunately, you cannot associate a Plexil Viewer with this application, without making a very simple modification (the '-v' option) to how it is started.

Hope this helps,
Mike

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.

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

[Catherine S. <Cat...@ti...>]

Hello,
      I would like to know if it is possible to open the Plexil Viewer to watch a plan execution process that already started before the Viewer was opened. Here's how I tried to do so:

1. Run a plan (example: PlanA.plx) via the command line in a terminal window ("Terminal Window 1").
2. While the PlanA.plx is being executed, open another terminal window ("Terminal Window 2") and open the Plexil Viewer.
3. Load PlanA.plx in the Plexil Viewer and watch the execution process that was started in Terminal Window 1.

I can only get the Plexil Viewer to start another execution process for PlanA.plx, not watch the execution process that started from Terminal Window 1.

Any help or response would be appreciated. Thank you!

Re: [plexil-support] IPC adapter and lookup on change

[Dalal, M. (ARC-TI)[S. G. T. I. (S. Inc.)] <mic...@na...>]

Hello Andrew,

I'm afraid we are not aware of any existing examples of LookupOnChange over IPC.  Time permitting, one of our engineers may send you tips on how to approach it.  We will be very interested to know if you have success implementing this.  Feel free to send us more detailed questions.

As a side note:

You are apparently using the main trunk of the PLEXIL development tree.  There is a significant enhancement of PLEXIL (mostly internals) available on the 'plexil-3' SVN branch.  In fact, this branch has been used exclusively for PLEXIL projects at NASA for over a year now.  

Unfortunately this branch is not ready to merge onto the trunk and create a major new PLEXIL version, because several tasks are unfinished.  One of them happens to be getting IPC built.  The branch uses Gnu automake/autoconf, and IPC has not yet been converted.  If you happen to be interested in this task, or know someone who is, we'd welcome your contribution to our open source release and would acknowledge this in our release.  

If you're interested in using the branch, I'll send you instructions on how to build it, as the process differs from the main trunk and requires a few more steps…another thing we'd like to streamline.

Best,
Mike

Hi Andrew,

Glad to hear of your interest in PLEXIL and that you've made some progress with an IPC adapter.  True, Robosim does not exercise LookupOnChange.  I'm not aware of an example of IPC-based LookupOnChange.  Let me discuss this with the team, and hopefully we'll have a suggestion for you soon.

Best,
Mike

[plexil-support] IPC adapter and lookup on change

[Andrew H. <and...@gm...>]

Hello,

   I have been able to follow along with the robosim example application and have created a simple plexil to ipc bridge adapter based on it.  However it seems that the robosim example does not use the lookup on change feature where it would send data to the executive only when data changed.  Is there an example showing how to get the lookup on change message working over ipc to the plexil executive?  Thanks for any help you could provide.

Re: [plexil-support] Makefile problems

[Chuck F. <Cha...@na...>]

Thanks for the report and the suggested fix. This problem was first reported about a month ago and is fixed in the trunk, although not exactly in the fashion you propose. Please try it and let me know if our fix is sufficient.

The exec-refactoring-2011 branch has been frozen. It was copied to the SVN trunk some months ago. Please switch to the trunk at your convenience.

The 1.7.1 branch has also been frozen and should not be used.

[plexil-support] Patch allowing rev 1260 to work under Cygwin

[Jesse H. <jho...@si...>]

Hello PLEXIL team,

We've been able to get (the core parts of) revision 1260 working under
Cygwin. The attached tarball contains the patch. It's more than just a
diff, unfortunately. See the README for instructions.

I attempted to update the patch to work against the head revision but
ran into linking problems with tinyxml. Unfortunately I don't have time
to pursue this further. Some of this patch is redundant given updates
made to PLEXIL since rev 1260.

Feel free to contact us if you have questions. I'm cc'ing my colleague
Mike Pelican as an alternative contact as it will be difficult to reach
me for a while.


Thanks,

Jesse Hostetler

Re: [plexil-support] plexil question

[K. M. D. <Mic...@na...>]

Yoshi,

We are working with a local company who is developing PLEXIL  
authoring tools under an SBIR contract.  They have considered  
creating a FSM package.  If you can tell us a little more about your  
needs, this would be helpful input that I'll pass on to them.

Please note that the source code version of our software is currently  
ahead of the packaged distributions.  They will be in sync when we  
make a new distribution within the next two weeks.

Best,
Mike

Re: [plexil-support] plexil question

[Chuck F. <Cha...@na...>]

The PLEXIL external interface assumes C or C++ as the language for  
external calls.  I'm not familiar with interfacing between C and  
Python.  A quick web search turns up SWIG, http://www.swig.org/ , as  
one possibility.

The Doxygen links will be corrected in the forthcoming release.  The  
external interface API is changing significantly, so this  
documentation will be heavily revised.  Thank you for the report.

Re: [plexil-support] plexil question

Thank you for the quick reply.

I've got another question:
Our simulation tool has a Python interface, but from the
online reference manual, it is not clear how to call such
external program/functions.

Chapter 5 of Universal Executive's reference manual seems
to be related, but I am not sure. Links to doxygen seems to be
broken there?

Re: [plexil-support] plexil question

[Chuck F. <Cha...@na...>]

Hello Yoshi.

We don't provide a finite state machine package for PLEXIL.  I'm not  
aware of any in our user base.  I would expect such a package to be  
straightforward to write.

We plan to release a new version of PLEXIL before the end of April.

Thanks for your interest!

[plexil-support] plexil question

[<ku...@gm...>]

Hello,

I was wondering if there is a finite state machine package
available in PLEXIL. If not, how easy it is to create such
template? I am thinking of using PLEXIL to describe
high-level mission sequences (that involve multiple FSM)
and run them in the simulation environment that we have.

Also, is there any plan for a new software release?

I have not really used PLEXIL (only read the reference
manual), and appreciate your help.

thanks,
Yoshi
