Indeed, thanks a lot, I really appreciate your input as usual. I updated
the code in the repository [0]

There is still a minor annoyance. In the manual [1] there is a 'modules'
keyword documented for the procedure 'coverage-data->lcov' but in the
current code that argument is gone [2]

Is there a known workaround to get the coverage only for a given module?

TIA!
