Running YAPF on itself
----------------------

To run YAPF on all of YAPF::

 $ PYTHONPATH=$PWD/yapf python -m yapf -i -r .

To run YAPF on just the files changed in the current git branch::

 $ PYTHONPATH=$PWD/yapf python -m yapf -i $(git diff --name-only @{upstream})

Releasing a new version
-----------------------

* Run tests: python setup.py test
  [don't forget to run with at least Python 3.7 and 3.11]

* Bump version in yapf/__init__.py

* Build source distribution: python setup.py sdist

* Check it looks OK, install it onto a virtualenv, run tests, run yapf as a tool

* Build release: python setup.py sdist bdist_wheel

* Push to PyPI: twine upload dist/*

* Test in a clean virtualenv that 'pip install yapf' works with the new version

* Commit the version bump; add tag with git tag v<VERSION_NUM>; git push --tags

TODO: discuss how to use tox to make virtualenv testing easier.
