There is not. Your options are to use the GDB/MI interface or use the
python api.

If you want to use the GDB/MI interface, congratulations, you have to
read and interpret the spec, find all the bugs in it, write a parser
to support all the cases and test it against old and new versions of
GDB. It's a daunting task, I know, I'm working on it.

I don't expect to be done implementing and testing this for a long time.

If you want to use the GDB python interface you need to understand that
many GDB deployments do not have the python interpreter built into them.
Also, I'm not sure anyone has successfully tried to control GDB through
the python interface while allowing the user to use the cli interface.
Not sure if this is your goal.

Both of these approaches are possible, but not for the faint of heart.

Good luck!
