This implements PEP 621, obviating the need for `setup.py`, `setup.cfg`,
and `MANIFEST.in`. The build backend Hatchling (of which I am a
maintainer in the PyPA) is now used as that is the default in the
official Python packaging tutorial. Hatchling is available on all the
major distribution channels such as Debian, Fedora, and many more.
## Python support
The earliest supported Python 3 version of Hatchling is 3.7, therefore
I've also set that as the minimum here. Python 3.6 is EOL and other
build backends like flit-core and setuptools also dropped support.
Python 3.6 accounted for 3-4% of downloads in the last month.
## Plugins
Configuration is now completely static with the help of 3 plugins:
### Readme
hynek's hatch-fancy-pypi-readme allows for the dynamic construction of
the readme which was previously coded up in `setup.py`. Now it's simply:
```toml
[tool.hatch.metadata.hooks.fancy-pypi-readme]
content-type = "text/markdown"
fragments = [
{ path = "README.md" },
{ path = "CHANGES.md" },
]
```
### Versioning
hatch-vcs is currently just a wrapper around setuptools-scm (which
despite the legacy naming is actually now decoupled from setuptools):
```toml
[tool.hatch.version]
source = "vcs"
[tool.hatch.build.hooks.vcs]
version-file = "src/_black_version.py"
template = '''
version = "{version}"
'''
```
### mypyc
hatch-mypyc offers many benefits over the existing approach:
- No need to manually select files for inclusion
- Avoids the need for the current CI workaround for https://github.com/mypyc/mypyc/issues/946
- Intermediate artifacts (like `build/`) from setuptools and mypyc
itself no longer clutter the project directory
- Runtime dependencies required at build time no longer need to be
manually redeclared as this is a built-in option of Hatchling

* Move 311 tests to install aiohttp without C extensions
- Configure tox to install aiohttp without extensions
- i.e. use `AIOHTTP_NO_EXTENSIONS=1` for pip install
- This allows us to reenable blackd tests that use aiohttp testing helpers etc.
- Had to ignore `cgi` module deprecation warning
- Filed issue for aiohttp to fix: https://github.com/aio-libs/aiohttp/issues/6905
Test:
- `/tmp/tb/bin/tox -e 311`
* Fix formatting + linting
* Add latest aiohttp for loop fix + Try to exempt deprecation warning but failed - will ask for help
* Remove unnecessary warning ignore

- Had to exempt blackd tests for now due to aiohttp
- Skip by using `sys.version_info` tuple
- aiohttp does not compile in 3.11 yet - refer to #3230
- Add a deadsnakes ubuntu workflow to run 3.11-dev to ensure we don't regress
- Have it also format ourselves
Test:
- `tox -e 311`

*blib2to3's support was left untouched because: 1) I don't want to touch
parsing machinery, and 2) it'll allow us to provide a more useful error
message if someone does try to format Python 2 code.
To summarise, based on what was discussed in that issue:
due to not being able to parse automagics (e.g. pip install black)
without a running IPython kernel, cells with syntax which is parseable
by neither ast.parse nor IPython will be skipped cells with multiline
magics will be skipped trailing semicolons will be preserved, as they
are often put there intentionally in Jupyter Notebooks to suppress
unnecessary output

The random asyncio bug is just too frequent and annoying to be
worth the speed improvements. Our test suite is already quite fast.
Random test failures hurt for 3 reasons, 1) they are discouraging for
new contributors who won't understand it's out of their control, 2)
it's annoying and time consuming to rerun the workflow, and 3) it
makes single job failures feel less important (even they should be
treated as important!).
* Speed up test suite via distributed testing
Since we now run the test suite twice, one with Python 2 and another
without, full test runs are getting pretty slow. Let's try to
fix that with parallization.
Also use verbose mode on CI since more logs is usually better since
getting more is quite literally impossible.
The main issue we'll face with this is we'll hit
https://github.com/pytest-dev/pytest-xdist/issues/620 sometimes
(although pretty rarely). I suppose we can test this and see if how bad
this bug is for us, and revert if necessary down the line.
Also let's have some colours 🎉
Fixes#1738. Fixes#1812.
Previously, Black removed leading and trailing spaces in multiline docstrings but failed to remove them from one-line docstrings.
