Vim plugin docs improvements (#3468)
* 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.

Remove whitespaces of whitespace-only files (#3348)
Currently, empty and whitespace-only (with or without newlines) are
not modified. In some discussions (issues and pull requests) consensus
was to reformat whitespace-only files to empty or single-character
files, preserving line endings when possible. With that said, this
commit introduces the following behaviors:
* Empty files are left as is
* Whitespace-only files (no newline) reformat into empty files
* Whitespace-only files (1 or more newlines) reformat into a single
newline character
To implement these changes, we moved the initial check at
`format_file_contents` that raises `NothingChanged` if the source
(with no whitespaces) is an empty string. In the case of *.ipynb
files, `format_ipynb_string` checks a similar condition and removed
whitespaces. In the case of Python files, `format_str_once` includes a
check on the output that returns the correct newline character if
possible or an empty string otherwise.
Compare each .gitignore found with an appropiate relative path (#3338)
* Apply .gitignore files considering their location
When a .gitignore file contains the special rule to ignore every
subfolder content (`*/*`) and the file is located in a subfolder
relative to where the command is executed (root), the rule is
incorrectly applied and ignores every file at the same level of the
.gitignore file.
The reason for this is that the `gitignore` variable accumulates the
rules found in each .gitignore while traversing files and directories
recursively. This makes sense and, in general, works as expected. The
problem is that the gitignore rules are applied using as the relative
path from root to target directory as a reference. This is the cause
of the bug.
The implemented solution keeps track of every .gitignore file found
while traversing the targets and the absolute location of each
.gitignore file. Then, when matching files to the .gitignore rules,
compare each set of rules with the appropiate relative path to the
candidate target file.
To make this possible, we changed the single `gitignore` object with a
dictionary of similar objects, where the corresponding key is the
absolute path to the folder that contains that .gitignore file. This
required changing the signature of the `get_sources` function. Also, we
introduce a `is_ignored` function that compares a file with every set
of rules. Finally, some tests required an update to pass the gitignore
object in the new format.

* Test .gitignore with `*/*` is applied correctly
The test contains three cases: 1) when the .gitignore with the special
rule to ignore every subfolder and its contents (*/*) is in the root,
2) when the file is inside a subfolder relative to root (nested), and
3) when the target folder contains the .gitignore and root is a parent
folder of the target. In all of these cases, we compare the files that
are visible by Black with a known list of paths containing the
expected values.
Before the fix introduced in the previous commit, these tests failed
when the .gitignore file was nested (second case). Now, the test is
passed for all cases.

* Small refactor to improve code readability
These changes are small improvements to improve code readability:
rename a variable to a more descriptive name (from `exclude_is_None`

annotation for `gitignore` variable (from typing comment to
Python-style typing annotation), and replace an if-else block with a
single dictionary definition (in this case, we need to compare keys
instead of values, meaning that the change works)

* Make nested function a top-level function

Apply .gitignore correctly in every source entry (#3336)
When passing multiple src directories, the root gitignore was only
applied to the first processed source. The reason is that, in the
first source, exclude is `None`, but then the value gets overridden by
`re_compile_maybe_verbose(DEFAULT_EXCLUDES)`, so in the next iteration
where the source is a directory, the condition is not met and sets the
value of `gitignore` to `None`.
To fix this problem, we store a boolean indicating if `exclude` is
`None` and set the value of `exclude` to its default value if that's
the case. This makes sure that the flow enters the correct condition on
following iterations and also keeps the original value if the condition
is not met.
Also, the value of `gitignore` is initialized as `None` and overriden
if necessary. The value of `root_gitignore` is always calculated to
avoid using additional variables (at the small cost of additional
computations).

Add option to skip the first line of source code (#3299)
* 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.
Signed-off-by: Antonio Ossa Guerra <aaossa@uc.cl>
* 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).

Switch build backend to Hatchling (#3233)
This implements PEP 621, obviating the need for `setup.py`, `setup.cfg`,

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:

- 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

Fix a crash when `# fmt: on` is used on a different block level than `# fmt: off` (#3281)
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`.

Update stable branch after publishing to PyPI (#3223)
We've decided to a) convert stable back into a branch and b) to update
it immediately as part of the release process. We may as well automate
it. And about going back to a branch ...
Git tags are not the right tool, at all[^1]. They come with the
expectation that they will never change. Things will not work as
expected if they do change, doubly so if they change regularly. Once
you pull stable from the remote and it's copied in your local
repository, no matter how many times you run git pull you'll never see
it get updated automatically. Your only recourse is to delete the tag
via `git tag -d stable` before pulling.
This gets annoying really quickly since stable is supposed to be the
solution for folks "who want to move along as Black developers deem
the newest version reliable."[^2] See this comment for how this impacts
users using our Vim plugin[^3]. It also affects us developers[^4]. If
you have stable locally, once we cut a new release and update the stable
tag, a simple `git pull` / `git fetch` will not pull down the updated
stable tag. Unless you remember to delete stable before pulling, stable
will become stale and useless.
You can argue this is a good thing ("people should explicitly opt into
updating stable"), but IMO it does not match user expectations nor
developer expectations[^5]. Especially since not all our integrations
that use stable are bound by this security measure, for example our
GitHub Action (since it does a clean fetch of the repository every time
it's used). I believe consistency would be good here.
Finally, ever since we switched to a tag, we've been facing issues with
ReadTheDocs not picking up updates to stable unless we force a rebuild.
The initial rebuild on the stable update just pulls the commit the tag
previously pointed to. I'm not sure if switching back to a branch will
fix this, but I'd wager it will.
[^4]: In fairness, most folks working on Black probably don't use the
`stable` ref anyway, especially us maintainers who'd know what is
the latest version by heart, but it'd still be nice to make it
usable for local dev though.
[^5]: Also what benefit does a `stable` ref have over explicit version
tags like `22.6.0`? If you're going to opt into some odd pin
mechanism, might as well use explicit version tags for clarity
and consistency.

Add parens around implicit string concatenations where it increases readability (#3162)
Adds parentheses around implicit string concatenations when it's inside
a list, set, or tuple. Except when it's only element and there's no trailing
comma.
Looking at the order of the transformers here, we need to "wrap in
parens" before string_split runs. So my solution is to introduce a
"collaboration" between StringSplitter and StringParenWrapper where the
splitter "skips" the split until the wrapper adds the parens (and then
the line after the paren is split by StringSplitter) in another pass.
I have also considered an alternative approach, where I tried to add a
different "string paren wrapper" class, and it runs before string_split.
Then I found out it requires a different do_transform implementation
than StringParenWrapper.do_transform, since the later assumes it runs
after the delimiter_split transform. So I stopped researching that
route.
Originally function calls were also included in this change, but given
missing commas should usually result in a runtime error and the scary
amount of changes this cause on downstream code, they were removed in
later revisions.

Delay worker count determination
os.cpu_count() can return None (sounds like a super arcane edge case
though) so the type annotation for the `workers` parameter of
`black.main` is wrong. This *could* technically cause a runtime
TypeError since it'd trip one of mypyc's runtime type checks so we
might as well fix it.
Reading the documentation (and cross-checking with the source code),
you are actually allowed to pass None as `max_workers` to
`concurrent.futures.ProcessPoolExecutor`. If it is None, the pool
initializer will simply call os.cpu_count() [^1] (defaulting to 1 if it
returns None [^2]). It'll even round down the worker count to a level
that's safe for Windows.
... so theoretically we don't even need to call os.cpu_count()
ourselves, but our Windows limit is 60 (unlike the stdlib's 61) and I'd
prefer not accidentally reintroducing a crash on machines with many,
many CPU cores.
