Revision history [back]

This is not currently supported, but could be implemented. First as background info, rqt_shell offers three different backends for the actual command shell:

1) one doing a simple single command shell call for each command given

2) one based on the spyder projects shell

3) one using an actual XTerm instance and just embedding its window into rqt_gui

For 1) the script would have to be executed every time before the command, since the shell used only lives for the execution time of that single command.

For 2) the script has to be run once after the shell is set up.

For 3) the script would have to be passed as command line parameter when starting the XTerm instance.

Please feel free to supply patches implementing any or preferably all of these.
