* add entry in CHANGES.md, make the style change only in preview mode
The idea behind this change is that we stop looking into previous body to determine if there should be a blank before a function or class definition.
Input:
```python
import sys
if sys.version_info > (3, 7):
class Nested1:
assignment = 1
def function_definition(self): ...
def f1(self) -> str: ...
class Nested2:
def function_definition(self): ...
assignment = 1
def f2(self) -> str: ...
if sys.version_info > (3, 7):
def nested1():
assignment = 1
def function_definition(self): ...
def f1(self) -> str: ...
def nested2():
def function_definition(self): ...
assignment = 1
def f2(self) -> str: ...
```
Stable style
```python
import sys
if sys.version_info > (3, 7):
class Nested1:
assignment = 1
def function_definition(self): ...
def f1(self) -> str: ...
class Nested2:
def function_definition(self): ...
assignment = 1
def f2(self) -> str: ...
if sys.version_info > (3, 7):
def nested1():
assignment = 1
def function_definition(self): ...
def f1(self) -> str: ...
def nested2():
def function_definition(self): ...
assignment = 1
def f2(self) -> str: ...
```
In the stable formatting, we have a blank line sometimes, not depending on the previous statement on the same level, but on the last (potentially nested) statement in the previous body.
#2783/#3564 fixes this for classes in preview style:
```python
import sys
if sys.version_info > (3, 7):
class Nested1:
assignment = 1
def function_definition(self): ...
def f1(self) -> str: ...
class Nested2:
def function_definition(self): ...
assignment = 1
def f2(self) -> str: ...
if sys.version_info > (3, 7):
def nested1():
assignment = 1
def function_definition(self): ...
def f1(self) -> str: ...
def nested2():
def function_definition(self): ...
assignment = 1
def f2(self) -> str: ...
```
This PR additionally fixes this for function definitions:
```python
if sys.version_info > (3, 7):
if sys.platform == "win32":
assignment = 1
def function_definition(self): ...
def f1(self) -> str: ...
if sys.platform != "win32":

assignment = 1
def function_definition(self): ...
class F1: ...
if sys.platform != "win32":
def function_definition(self): ...
assignment = 1
class F2: ...
```

IPython is a very expensive import, like, at least 300ms. I'd also
venture that it's much more common than tokenize-rt, which is like 30ms.
I work in a repo where I use black, have IPython installed and there
happen to be a couple notebooks (that we don't want formatted). I know I
can force exclude ipynb, but this change doesn't really have a cost.
Currently the verbose logging for "Sources to be formatted" is a little
suspect in that it is a completely different code path from
`get_sources`.
This can result in bugs like https://github.com/psf/black/pull/3216#issuecomment-1213557359
and generally limits the value of these logs.
This does change the "when" of this log, but the colours help separate
it from the even more verbose logs.
Several new versions of mypyc has been released since the last upgrade, and they include some performance improvements which could make the compiled version of Black run faster.
https://mypy-lang.org/news.html
The latest version of hatch-mypyc allows being installed next the 1.x series of mypy.
Avoids a Python 3.12 deprecation warning.
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`.
This patch changes the preview style so that string splitters respect
Unicode East Asian Width[^1] property. If you are not familiar to CJK
languages it is not clear immediately. Let me elaborate with some
examples.
Traditionally, East Asian characters (including punctuation) have
taken up space twice than European letters and stops when they are
rendered in monospace typeset. Compare the following characters:
```
abcdefg.
글、字。
```
The characters at the first line are half-width, and the second line
are full-width. (Also note that the last character with a small
circle, the East Asian period, is also full-width.) Therefore, if we
want to prevent those full-width characters to exceed the maximum
columns per line, we need to count their *width* rather than the number
of characters. Again, the following characters:
```
글、字。
```
These are just 4 characters, but their total width is 8.
Suppose we want to maintain up to 4 columns per line with the following
text:
```
abcdefg.
글、字。
```
How should it be then? We want it to look like:
```
abcd
efg.
글、
字。
```
However, Black currently turns it into like this:
```
abcd
efg.
글、字。
```
It's because Black currently counts the number of characters in the line
instead of measuring their width. So, how could we measure the width?
How can we tell if a character is full- or half-width? What if half-width
characters and full-width ones are mixed in a line? That's why Unicode
defined an attribute named `East_Asian_Width`. Unicode grouped every
single character according to their width in fixed-width typeset.
This partially addresses #1197, but only for string splitters. The other
parts need to be fixed as well in future patches.
This was implemented by copying rich's own approach to handling wide
characters: generate a table using wcwidth, check it into source
control, and use in to drive helper functions in Black's logic. This
gets us the best of both worlds: accuracy and performance (and let's us
update as per our stability policy too!).

Fixes#3506
We can't simply escape the quotes in a naked f-string when merging string groups, because backslashes are invalid.
The quotes in f-string expressions should be toggled (this is safe since quotes can't be reused).
This fix also means implicitly concatenated f-strings with different quotes can now be merged or quote-normalized by changing the quotes used in expressions. e.g.:
```diff
raise sa_exc.UnboundExecutionError(
"Could not locate a bind configured on "
- f'{", ".join(context)} or this Session.'
+ f"{', '.join(context)} or this Session."
)
```
When trying to format a project from the outside, the verbose output
shows says that there are symbolic links that points outside of the
project, but displays the wrong project path, meaning that these
messages are false positives.
This bug is triggered when the command is executed from outside a
project on a folder inside it, causing an inconsistency between the
path to the detected project root and the relative path to the target
contents.
The fix is to normalize the target path using the project root before
processing the sources, which removes the presence of the incorrect
messages.
---
The test attemps to emulate the behavior of the CLI as closely as
posible by patching some `pathlib.Path` methods and passing certain
reference paths to the context object and `black.get_sources`.
Before the associated fix was introduced, this test failed because
some of the captured files reported the presence of a symlink due to
an incorrectly formated path. The test also asserts that only a single
file is reported as ignored, which is part of the expected behavior.

* 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.

Fixes#3414.
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.

* 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`
to `using_default_exclude`), use a better syntax to include the type
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

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).

Provide a configuration parameter to the Vim plugin which will allow the

* 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).

the source to `format_file_contents` and put the header back once we
get the formatted result.

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`.

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.
`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

There are a number of places this behaviour could be patched, for
instance, it's quite tempting to patch it in `get_sources`. However
I believe we generally have the invariant that project root contains all
files we want to format, in which case it seems prudent to keep that
invariant.
This also improves the accuracy of the "sources to be formatted" log
message with --stdin-filename.

These errors are expected for now and aren't a cause for concern so
let's remove them to stop worrying users (and new issues from being
opened). We can improve the blib2to3 caching mechanism to write its
cache at the end of a successful command line invocation later.
As mentioned in GH-3185, when using Black as a Vim plugin, especially
automatically on save, the plugin's messages can be confusing, as
nothing indicates that they come from Black.

When the Leaf node with `# fmt: skip` is a NEWLINE inside a `suite`
Node, the nodes to ignore should be from the siblings of the parent
`suite` Node.
There is a also a special case for the ASYNC token, where it expands
to the grandparent Node where the ASYNC token is.
This fixes GH-2646, GH-3126, GH-2680, GH-2421, GH-2339, and GH-2138.
The former was a regression I introduced a long time ago. To avoid
changing the stable style too much, the regression is only fixed if
--preview is enabled
Annoyingly enough, as we currently always enforce a second format pass if
changes were made, there's no good way to prove the existence of the
docstring quote normalization instability issue. For posterity, here's
one failing example:

* Move to explicitly creating a new loop
- >= 3.10 add a warning that `get_event_loop` will not automatically create a loop
- Move to explicit API
Test:
- `python3.11 -m venv --upgrade-deps /tmp/tb`
- `/tmp/tb/bin/pip install -e .`
- Install deps and no blackd as aiohttp + yarl can't build still with 3.11
- https://github.com/aio-libs/aiohttp/issues/6600
- `export PYTHONWARNINGS=error`
```
cooper@l33t:~/repos/black$ /tmp/tb/bin/black .

Doing so is invalid. Note this only fixes the preview style since the
logic putting closing docstring quotes on their own line if they violate
the line length limit is quite new.
