Running "source" command before the script in the debug configuration Follow Mahmood Naderan Created September 19, 2020 16:45 Hi, In the configuration page, I can enter python script and options. For the source command, I see "Before launch: Activate tool window" and I select "Run external tool". However, when I put source in front of the "Program" and file.rc in front of the "Arguments", I get the error that "source program is not recognized". Problem is that source command is a shell internal and it is not a program like ls or grep. I didn't find information on how to use source command. Please see the pictures below: How can I fix that? Any idea?
