Wing IDE 8 now supports autoformatting w/ Black natively 🎉

Co-authored-by: Richard Si <[email protected]>

see: actions/runner#716

*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.

Black would now echo the location that it determined as the root path
for the project if `--verbose` is enabled by the user, according to
which it chooses the SRC paths, i.e. the absolute path of the project
is `{root}/{src}`.

Closes psf#1880

Resolves psf#2759

Fixes psf#2742.

This PR adds the ability to configure additional python cell magics. This
will allow formatting cells in Jupyter Notebooks that are using custom (python)
magics.

Closes psf#2774

- Add Furo dependency to docs/requirements.txt
- Drop a fair bit of theme configuration
- Fix the toctree declarations in index.rst
- Move stuff around as Furo isn't 100% compatible with Alabaster

Furo was chosen as it provides excellent mobile support, user
controllable light/dark theming, and is overall easier to read

Fixes psf#2506

``XDG_CACHE_HOME`` does not work on Windows. To allow for users to set a custom cache directory on all systems I added a new environment variable ``BLACK_CACHE_DIR`` to set the cache directory. The default remains the same so users will only notice a change if that environment variable is set.

The specific use case I have for this is I need to run black on in different processes at the same time. There is a race condition with the cache pickle file that made this rather difficult. A custom cache directory will remove the race condition.

I created ``get_cache_dir`` function in order to test the logic. This is only used to set the ``CACHE_DIR`` constant.

Y'all deserve it :)

This PR is intended to have no change to semantics.

This is in preparation for psf#2784 which will likely introduce more logic
that depends on `current_line.depth`.

Inlining the subtraction gets rid of offsetting and makes it much easier
to see what the result will be.

Closes psf#2360: I'd like to make passing SRC or `--code` mandatory and the arguments mutually exclusive. This will change our (partially already broken) promises of CLI behavior, but I'll comment below.

Since power operators almost always have the highest binding power in expressions, it's often more readable to hug it with its operands. The main exception to this is when its operands are non-trivial in which case the power operator will not hug, the rule for this is the following:

> For power ops, an operand is considered "simple" if it's only a NAME, numeric CONSTANT, or attribute access (chained attribute access is allowed), with or without a preceding unary operator. 

Fixes psfGH-538.
Closes psfGH-2095.

The previous run-twice logic only affected the stability checks but not the output. Now, we actually output the twice-formatted code.

Found by the fuzzer. Repro case:

	python -m black -c 'importA;()<<0**0#'

At the moment, it's just a source of spurious CI failures and busywork
updating the configuration file.

Unlike diff-shades, it is run across many different platforms and
Python versions, but that doesn't seem essential. We already run unit
tests across platforms and versions.

I chose to leave the code around for now in case somebody is using it,
but CI will no longer run it.

…sf#2820)

Fixes psf#2651. Fixes psf#2754. Fixes psf#2518. Fixes psf#2321.

This adds a test that lists a number of cases of unstable formatting
that we have seen in the issue tracker. Checking it in will ensure
that we don't regress on these cases.

Closes psf#1256: I reworded our style docs to be more explicit about the style we're aiming for and how it is changed (or isn't).

It turns out "simple_stmt" isn't that simple: it can contain multiple
statements separated by semicolons. Invisible parenthesis logic for
arithmetic expressions only looked at the first child of simple_stmt.
This causes instability in the presence of semicolons, since the next
run through the statement following the semicolon will be the first
child of another simple_stmt.

I believe this along with psf#2572 fix the known stability issues.

It was causing stability issues because the first pass
could cause a "magic trailing comma" to appear, meaning
that the second pass might get a different result. It's
not critical.

Some things format differently (with extra parens)

I did this manually for the last few releases and I think it's going to be
helpful in the future too. Unfortunately this adds a little more work during
the release (sorry @cooperlees).

This change will also improve the merge conflict situation a bit, because
changes to different sections won't merge conflict.

For the last release, the sections were in a kind of random order. In the
template I put highlights and "Style" first because they're most important
to users, and alphabetized the rest.

It was missing --diff as one of the default arguments passed.

  execute or colon is necessary.
- use an `augroup` (best practice) to prevent duplicate autocommands from
