Once in your development environment, create a virtualenv and install the appropriate linting tools and dependencies:
$ cd <path/to/diff-match-patch>
$ make venv
$ source .venv/bin/activate
This is a partial fork of diff-match-patch, with extra bits to make this a modern, friendly member of the Python packaging ecosystem. The library will be periodically updated with changes from the upstream project.
Since August 2024, Google's diff-match-patch library is archived, but there is a maintained fork.
If you would like to contribute fixes or improvements to the library itself, and not the packaging code, please submit them to the upstream maintained fork library directly.
