4 The uncompromising code formatter
5 =================================
6
7     “Any color you like.”
8
9 By using *Black*, you agree to cede control over minutiae of
10 hand-formatting. In return, *Black* gives you speed, determinism, and
11 freedom from `pycodestyle` nagging about formatting. You will save time
12 and mental energy for more important matters.
13
14 *Black* makes code review faster by producing the smallest diffs
15 possible. Blackened code looks the same regardless of the project
16 you're reading. Formatting becomes transparent after a while and you
17 can focus on the content instead.
18
19 Try it out now using the `Black Playground <https://black.vercel.app>`_.
20
21 .. admonition:: Note - Black is now stable!
22
23    *Black* is `successfully used <https://github.com/psf/black#used-by>`_ by
24    many projects, small and big. *Black* has a comprehensive test suite, with efficient
25    parallel tests, our own auto formatting and parallel Continuous Integration runner.
26    Now that we have become stable, you should not expect large formatting to changes in
27    the future. Stylistic changes will mostly be responses to bug reports and support for new Python
28    syntax.
29
30    Also, as a safety measure which slows down processing, *Black* will check that the
31    reformatted code still produces a valid AST that is effectively equivalent to the
32    original (see the
33    `Pragmatism <./the_black_code_style/current_style.html#pragmatism>`_
34    section for details). If you're feeling confident, use ``--fast``.

42 **Mike Bayer**, author of `SQLAlchemy <https://www.sqlalchemy.org/>`_:
43
44    *I can't think of any single tool in my entire programming career that has given me a
45    bigger productivity increase by its introduction. I can now do refactorings in about
46    1% of the keystrokes that it would have taken me previously when we had no way for
47    code to format itself.*
