How to use the diff exit codes in the cli?

Hi @aconrad,
I was searching a tool for coverage comparison for my organization. PyCobertura seems to provide what we need, especially the exit code 2:

2: the changes worsened the overall coverage

For the following example case:

where one-more-line-coverage.xml differs from the previous with one uncovered line added.
I just wonder how to catch this code in the terminal. Ultimately I want to use exit code 2 to fail the gitlab's pipeline.

P.S. Looking forward for the --format json feature.
Best regards

The exit code is what the command returns on the shell. You can access the exit code by typing $? right after running pycobertura, it's the syntax for getting the exit code of the last command run.

pycobertura ...
PYCOBERTURA_EXIT_CODE=$?
echo $PYCOBERTURA_EXIT_CODE

Let me know if that answers your questions.

ok, thank you very much, now I can use it for a better error explanation.

I also updated the README with the example above.
