What methods are there that I can use to run an ASP file from the main function of my C++ code?

I'm doing a project in which I am expected to control a simulated turtlebot using a C++ file, and use ASP code to construct an action plan that the robot can use to achieve a specified goal.

I'm using Ubuntu 14.04, SPARC (an ASP solver), ROS indigo, and gazebo.

Am I correct that SPARC is implemented in Java (this link)?

If this is the case, there are quite a few options:

  1. You can use Java Native Interface to interact with SPARC tool directly from c++ code
  2. Other option is to create a separate process from c++ code and communicate with it via stdout/files
  3. You can implement ROS node in Java which accepts requests and uses SPARC as a library to process them. In this case your c++ doesn't care about exact SPARC implementation

Resume:

I would suggest you to try the last option. It's slightly more difficult than other 2 options, but it fits perfectly into ROS infrastructure.

  • Thank you very much for your answer. I went with option 2, using stdout (this is the option my supervisor recommended I use), and it worked very well. If you have the time, I would greatly appreciate your assistance with a follow-up question: http://stackoverflow.com/questions/43554833/how-do-i-use-output-from-sparc-solver-as-input-to-a-python-file – The Impossible Squish Apr 22 '17 at 03:17
