How to run an interactive external script from SKILL?

LoVyacheslavvVEMs

Hi,

I need to launch an external script from SKILL. The script itself is not under my control - it may be a shell script, Python script, executable, or any other program.

The important part is that the script may pause at arbitrary points and wait for user input from stdin. When this happens, I would like to prompt the user in Virtuoso (for example, using an AppForm), send the entered text back to the running process, and then continue its execution.

I know about system() and ipcBeginProcess(), but I'm not sure whether SKILL supports this kind of interactive communication with a child process.

Is there a supported way to:

  • launch an external interactive process from SKILL;
  • detect when it is waiting for input;
  • send user input back to the process while it is running?

Thanks in advance.

    Thank you very much for your reply!

    Unfortunately, due to circumstances beyond my control, I'm currently unable to authenticate, so I can't access the solution you linked.

    Would it be possible for you to post the solution here? It would really help me, and I think it could also be useful for other people who come across this thread in the future.

    Thank you in advance!
