Hi Ned, thanks for the quick reply. I am using your tool for my research,
which tries to determine how different program runs produce different
coverage (e.g., when a program runs with option -a it covers line 1,2 ,
and when runs with option -b it covers line 1,4). Thus I want to get the
Yes I realize the xml file does include those information but I would have
to parse it. So I thought if python-coverage already has something that
can output those then I don't have to parse the xml file.
I do use the --pylib (more specifically I have cover_pylib = True in the
.coveragerc). It does capture the coverage for stdlib files as expected,
and python-coverage report works fine. However the annotate command doesn't
seem to write the filename,cover files corresponding to the stdlib files.
