1 # The basics
2
3 An overview on contributing to the _Black_ project.
4
5 ## Technicalities
6
7 Development on the latest version of Python is preferred. As of this writing it's 3.9.
8 You can use any operating system.
9
10 Install development dependencies inside a virtual environment of your choice, for
11 example:
12
13 ```console
14 $ python3 -m venv .venv
15 $ source .venv/bin/activate
16 (.venv)$ pip install -r test_requirements.txt
17 (.venv)$ pip install -e .[d]
18 (.venv)$ pre-commit install
19 ```
20
21 Before submitting pull requests, run lints and tests with the following commands from
22 the root of the black repo:
23
24 ```console
25 # Linting
26 (.venv)$ pre-commit run -a
27
28 # Unit tests
29 (.venv)$ tox -e py
30
31 # Optional Fuzz testing
32 (.venv)$ tox -e fuzz
33 ```
34
35 ### News / Changelog Requirement
36
37 `Black` has CI that will check for an entry corresponding to your PR in `CHANGES.md`. If
38 you feel this PR does not require a changelog entry please state that in a comment and a
39 maintainer can add a `skip news` label to make the CI pass. Otherwise, please ensure you
40 have a line in the following format:
41
42 ```md
43 - `Black` is now more awesome (#X)
44 ```
45
46 Note that X should be your PR number, not issue number! To workout X, please use
47 [Next PR Number](https://ichard26.github.io/next-pr-number/?owner=psf&name=black). This
48 is not perfect but saves a lot of release overhead as now the releaser does not need to
49 go back and workout what to add to the `CHANGES.md` for each release.
50
51 ### Style Changes
52
53 If a change would affect the advertised code style, please modify the documentation (The
54 _Black_ code style) to reflect that change. Patches that fix unintended bugs in
55 formatting don't need to be mentioned separately though. If the change is implemented
56 with the `--preview` flag, please include the change in the future style document
57 instead and write the changelog entry under a dedicated "Preview changes" heading.
58
59 ### Docs Testing
60
61 If you make changes to docs, you can test they still build locally too.
62
63 ```console
64 (.venv)$ pip install -r docs/requirements.txt
65 (.venv)$ pip install [-e] .[d]
66 (.venv)$ sphinx-build -a -b html -W docs/ docs/_build/
67 ```
68
69 ## Hygiene
70
71 If you're fixing a bug, add a test. Run it first to confirm it fails, then fix the bug,
72 run it again to confirm it's really fixed.
73
74 If adding a new feature, add a test. In fact, always add a test. But wait, before adding
75 any large feature, first open an issue for us to discuss the idea first.
76
77 ## Finally
78
79 Thanks again for your interest in improving the project! You're taking action when most
80 people decide to sit and watch.
