A message from Sep, the creator of DeepDiff

👋 Hi there,

Thank you for using DeepDiff! As an engineer, I understand the frustration of wrestling with unruly data in pipelines. That's why I developed a new tool - Qluster to empower non-engineers to control and resolve data issues at scale autonomously and stop bugging the engineers! 🛠️

If you are going through this pain now, I would love to give you early access to Qluster and get your feedback.

Local dev

1. Clone the repo

2. Switch to the dev branch

3. Create your own branch

4. Install dependencies

   • Method 1: Use uv to install the dependencies: uv sync --all-extras.
   • Method 2: Use pip: pip install -e ".[cli,coverage,dev,docs,static,test]"

5. Build flit build

Contribute

1. Please make your PR against the dev branch
2. Please make sure that your PR has tests. Since DeepDiff is used in many sensitive data driven projects, we strive to maintain around 100% test coverage on the code.

Please run pytest --cov=deepdiff --runslow to see the coverage report. Note that the --runslow flag will run some slow tests too. In most cases you only want to run the fast tests which so you wont add the --runslow flag.

Or to see a more user friendly version, please run: pytest --cov=deepdiff --cov-report term-missing --runslow.

Thank you!
