coverage-reporter allows more complicated reporting of information from figleaf and other coverage tools.
However, unlike those tools, coverage-reporter provides the ability to munge the data on the way to reporting as desired.
For example, you can specify that you wish to only see the coverage for your current patch by specifying:
git diff | coverage-reporter --patch=stdin --patch-level=0 --summarize --annotate .
This will take the patch from git, read it and then only provide coverage information on those lines affected by your patch.
Another useful command is --minimum-missing=100 - if you have a large number of covered files, this will limit the display to only those missing more than 100 lines of coverage. Also useful is --minimum-missing=1, which doesn't print any status for those files that are completely covered.
