If you have already generated a report using pycodestyle , pyflakes , flake8 , pylint , checkstyle , checkstylexml , or findbugs you can pass the report to diff-quality. This is more efficient than letting diff-quality re-run pycodestyle , pyflakes , flake8 , pylint , checkstyle , or checkstylexml. Note that you must use the -f parseable option to generate the pylint report for pylint versions less than 1.

To specify a different compare branch:. Explicit exclusion of paths is possible for both diff-cover and diff-quality , while inclusion is only supported for diff-quality since 5. The exclude option works with fnmatch , include with glob. Both options can consume multiple values. Include options should be wrapped in double quotes to prevent shell globbing.

If the quality checker is already implemented as a Python package, great!

If not, create a Python package to host the plugin implementation. When your package is installed, diff-quality uses this information to look up the tool package and module based on the tool name provided to the --violations option of the diff-quality command, e.

After preprocessing the input files, it runs the Linux tools meld, gvimdiff, tkdiff, or kompare on these intermediate files. Amin I was just about to suggest the same when I saw your comment. I will not bore you with what has to be done with the second file. Do any of these or any program offer both line level and word level merging in a graphic environment? Hey Aaron, thanks for the article. Do you have any benchmark comparing the software?

I am asking because I use Meld and making a diff of a Mb SQL file just take forever, a little better if I turn off the syntax coloring but still take forever…. I mean, Kdiff3 is probably the best merge-tool available for any version control environment and I do use it roughly weekly.

However, after using it for 10 years, I still find its GUI barely usable. I would describe it as best tool for file merging despite horrific GUI.
