Hey guys,

I am developing a rqt plugin in Python at the moment and I am using the recommended IDE PyCharm.

When I get errors I always try to debug with print messages.

I am wondering is there a good debugging solution to debug a rqt plugin in PyCharm?

Thank you very much in advance!

Best regards

I realized now that I can debug my plugins by using the "Attach to Local Process" function (you can find it under "Run") and attach it to the rqt process. I had to change the ptrace settings to make it work by:

$ sudo su -

$ echo 0 > /proc/sys/kernel/yama/ptrace_scope

Maybe it'll help someone.
