Subtle difference: previously, timestamps in diff filenames had the
`+0000` separated from the timestamp by space. With this, the space is
there no more, and there is a colon, as in `+00:00`.

Revert deleted documentation on setting up Black using IntelliJ
external tool or file watcher utilities. These are still worth keeping
because some peole might not want to use a third-party plugin or
install Blackd's extra dependencies.

* Organize vim plugin section with headers to separate out Installation, Usage, and Troubleshooting for readability and easy linking
* Add missing plugin configuration options, with current defaults
* Add installation note for Arch Linux, now that the plugin is shipped with the python-black package (ref: https://bugs.archlinux.org/task/73024)
* Fix vim-plug specification to follow stable releases. Moving the same tag is an antipattern that doesn't re-resolve with vim-plug, see this discussion for more detail (https://github.com/junegunn/vim-plug/pull/720\#issuecomment-1105829356). Per vim-plug's maintainer's recommendation, use the 'tag' key instead with a shell wildcard. Wildcard should be '*.*.*' as that follows Black's versioning detailed here (https://black.readthedocs.io/en/latest/contributing/release_process.html\#cutting-a-release) and doesn't include current alpha releases.
Provide a configuration parameter to the Vim plugin which will allow the
plugin to skip setting up a virtualenv. This is useful when there is a
system installation of black (e.g. from a Linux distribution) which the
user prefers to use.
Using a virtualenv remains the default.

* Add option to skip the first line in source file
This commit adds a CLi option to skip the first line in the source
files, just like the Cpython command line allows [1]. By enabling the
flag, using `-x` or `--skip-source-first-line`, the first line is
removed temporarilly while the remaining contents are formatted. The
first line is added back before returning the formatted output.

* Add tests for `--skip-source-first-line` option
When the flag is disabled (default), black formats the entire source
file, as in every line. In the other hand, if the flag is enabled, by
using `-x` or `--skip-source-first-line`, the first line is retained
while the rest of the source is formatted and then is added back.
These tests use an empty Python file that contains invalid syntax in
its first line (`invalid_header.py`, at `miscellaneous/`). First,
Black is invoked without enabling the flag which should result in an
exit code different than 0. When the flag is enabled, Black is
expected to return a successful exit code and the header is expected
to be retained (even if its not valid Python syntax).

* Skip first source line at `format_file_in_place`
Instead of skipping the first source line at `format_file_contents`,
do it before. This allow us to find the correct newline and encoding
on the actual source code (everything that's after the header).
This change is also applied at Blackd: take the header before passing
the source to `format_file_contents` and put the header back once we
get the formatted result.

* Test output newlines when skipping first line
When skipping the first line of source code, the reference newline must

To run the formatter on Jupyter Notebooks, Black must be installed
with an extra dependency (`black[jupyter]`). This commit adds an
optional argument to install Black with this dependency when using the
official GitHub Action [1]. To enable the formatter on Jupyter
Notebooks, just add `jupyter: true` as an argument. Feature requested
at [2].

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

Previously _Black_ produces invalid code because the `# fmt: on` is used on a different block level.
While _Black_ requires `# fmt: off` and `# fmt: on` to be used at the same block level, incorrect usage shouldn't cause crashes.
The formatting behavior this PR introduces is, the code below the initial `# fmt: off` block level will be turned off for formatting, when `# fmt: on` is used on a different level or there is no `# fmt: on`. This also matches the current behavior when `# fmt: off` is used at the top-level without a matching `# fmt: on`, it turns off formatting for everything below `# fmt: off`.

it too.

`black.reformat_many` depends on a lot of slow-to-import modules. When
formatting simply a single file, the time paid to import those modules
is totally wasted. So I moved `black.reformat_many` and its helpers
to `black.concurrency` which is now *only* imported if there's more
than one file to reformat. This way, running Black over a single file
is snappier
Here are the numbers before and after this patch running `python -m
black --version`:
- interpreted: 411 ms +- 9 ms -> 342 ms +- 7 ms: 1.20x faster
- compiled: 365 ms +- 15 ms -> 304 ms +- 7 ms: 1.20x faster

Now PRs will run two diff-shades jobs, "preview-changes" which formats
all projects with preview=True, and "assert-no-changes" which formats
all projects with preview=False. The latter also fails if any changes
were made.
Pushes to main will only run "preview-changes"
Also the workflow_dispatch feature was dropped since it was
complicating everything for little gain.
- use `Black` directly: the commands an autocommand runs are Ex commands, so no
execute or colon is necessary.
- use an `augroup` (best practice) to prevent duplicate autocommands from
hindering performance.
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.
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.
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 GH-538.
Closes GH-2095.

Fixes#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.
- 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
*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.
