I filter out certain source files by running the output of lcov --capture through a simple awk script. The output of lcov --capture has a very simple format and the awk script below filters out source files matching file_pattern. I think it is possible to adapt the script to make it filter functions instead of file names.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
