I have X number of test input files for a python program and for each file, I want to generate debug configuration for each input file in Eclipse skipping the painful process of clicks.
Does anybody know which directory/file Eclipse internally uses to store the debug configuration especially the argument to the program?
If you mean the Debug Configuration for the launch that is stored in a xxx.launch file in the workspace .metadata/.plugins/org.eclipse.debug.core/.launches directory.
Eclipse has extensive APIs for launch configurations, see for example this question
