-## The *Black* code style
+_Black_ is a well-behaved Unix-style command-line tool:

 
 

-*Black* reformats entire files in place.  It is not configurable.  It
-doesn't take previous formatting into account.  It doesn't reformat
-blocks that start with `# fmt: off` and end with `# fmt: on`.  It also
-recognizes [YAPF](https://github.com/google/yapf)'s block comments to
-the same effect, as a courtesy for straddling code.
+- it does nothing if no sources are passed to it;
+- it will read from standard input and write to standard output if `-` is used as the
+  filename;
+- it only outputs messages to users on standard error;
+- exits with code 0 unless an internal error occurred (or `--check` was used).

 
 

+### Using _Black_ with other tools

 
 

-### How *Black* wraps lines
+While _Black_ enforces formatting that conforms to PEP 8, other tools may raise warnings
+about _Black_'s changes or will overwrite _Black_'s changes. A good example of this is
+[isort](https://pypi.org/p/isort). Since _Black_ is barely configurable, these tools
+should be configured to neither warn about nor overwrite _Black_'s changes.

 
 

-*Black* ignores previous formatting and applies uniform horizontal
-and vertical whitespace to your code.  The rules for horizontal
-whitespace can be summarized as: do whatever makes `pycodestyle` happy.
-The coding style used by *Black* can be viewed as a strict subset of
-PEP 8.
+Actual details on _Black_ compatible configurations for various tools can be found in
+[compatible_configs](https://github.com/psf/black/blob/master/docs/compatible_configs.md).

 
 

-As for vertical whitespace, *Black* tries to render one full expression
-or simple statement per line.  If this fits the allotted line length,
-great.
-```py3
-# in:
+### Migrating your code style without ruining git blame

 
 

-l = [1,
-     2,
-     3,
-]
+A long-standing argument against moving to automated code formatters like _Black_ is
+that the migration will clutter up the output of `git blame`. This was a valid argument,
+but since Git version 2.23, Git natively supports
+[ignoring revisions in blame](https://git-scm.com/docs/git-blame#Documentation/git-blame.txt---ignore-revltrevgt)
+with the `--ignore-rev` option. You can also pass a file listing the revisions to ignore
+using the `--ignore-revs-file` option. The changes made by the revision will be ignored
+when assigning blame. Lines modified by an ignored revision will be blamed on the
+previous revision that modified those lines.

 
 

-# out:
+So when migrating your project's code style to _Black_, reformat everything and commit
+the changes (preferably in one massive commit). Then put the full 40 characters commit
+identifier(s) into a file.

 
 

-l = [1, 2, 3]

 ```
 ```

-
-If not, *Black* will look at the contents of the first outer matching
-brackets and put that in a separate indented line.
-```py3
-# in:
-
-TracebackException.from_exception(exc, limit, lookup_lines, capture_locals)
-
-# out:
-
-TracebackException.from_exception(
-    exc, limit, lookup_lines, capture_locals
-)
+# Migrate code style to Black
+5b4ab991dede475d393e9d69ec388fd6bd949699

 ```
 
 ```
 

-If that still doesn't fit the bill, it will decompose the internal
-expression further using the same rule, indenting matching brackets
-every time.  If the contents of the matching brackets pair are
-comma-separated (like an argument list, or a dict literal, and so on)
-then *Black* will first try to keep them on the same line with the
-matching brackets.  If that doesn't work, it will put all of them in
-separate lines.
-```py3
-# in:
-
-def very_important_function(template: str, *variables, file: os.PathLike, debug: bool = False):
-    """Applies `variables` to the `template` and writes to `file`."""
-    with open(file, 'w') as f:
-        ...
-
-# out:
-
-def very_important_function(
-    template: str,
-    *variables,
-    file: os.PathLike,
-    debug: bool = False,
-):
-    """Applies `variables` to the `template` and writes to `file`."""
-    with open(file, "w") as f:
-        ...
-```
+Afterwards, you can pass that file to `git blame` and see clean and meaningful blame
+information.

 
 

-You might have noticed that closing brackets are always dedented and
-that a trailing comma is always added.  Such formatting produces smaller
-diffs; when you add or remove an element, it's always just one line.
-Also, having the closing bracket dedented provides a clear delimiter
-between two distinct sections of the code that otherwise share the same
-indentation level (like the arguments list and the docstring in the
-example above).
-
-If a data structure literal (tuple, list, set, dict) or a line of "from"
-imports cannot fit in the allotted length, it's always split into one
-element per line.  This minimizes diffs as well as enables readers of
-code to find which commit introduced a particular entry.  This also
-makes *Black* compatible with [isort](https://pypi.org/p/isort/).  Use
-`multi_line_output=3`, `include_trailing_comma=True`,
-`force_grid_wrap=0`, and `line_length=88` in your isort config.
-
-
-### Line length
-
-You probably noticed the peculiar default line length.  *Black* defaults
-to 88 characters per line, which happens to be 10% over 80.  This number
-was found to produce significantly shorter files than sticking with 80
-(the most popular), or even 79 (used by the standard library).  In
-general, [90-ish seems like the wise choice](https://youtu.be/wf-BqAjZb8M?t=260).
-
-If you're paid by the line of code you write, you can pass
-`--line-length` with a lower number.  *Black* will try to respect that.
-However, sometimes it won't be able to without breaking other rules.  In
-those rare cases, auto-formatted code will exceed your allotted limit.
-
-You can also increase it, but remember that people with sight disabilities
-find it harder to work with line lengths exceeding 100 characters.
-It also adversely affects side-by-side diff review  on typical screen
-resolutions.  Long lines also make it harder to present code neatly
-in documentation or talk slides.
-
-If you're using Flake8, you can bump `max-line-length` to 88 and forget
-about it.  Alternatively, use [Bugbear](https://github.com/PyCQA/flake8-bugbear)'s
-B950 warning instead of E501 and keep the max line length at 80 which
-you are probably already using.  You'd do it like this:
-```ini
-[flake8]
-max-line-length = 80
-...
-select = C,E,F,W,B,B950
-ignore = E501
+```console
+$ git blame important.py --ignore-revs-file .git-blame-ignore-revs
+7a1ae265 (John Smith 2019-04-15 15:55:13 -0400 1) def very_important_function(text, file):
+abdfd8b0 (Alice Doe  2019-09-23 11:39:32 -0400 2)     text = text.lstrip()
+7a1ae265 (John Smith 2019-04-15 15:55:13 -0400 3)     with open(file, "r+") as f:
+7a1ae265 (John Smith 2019-04-15 15:55:13 -0400 4)         f.write(formatted)

 ```
 
 ```
 

-You'll find *Black*'s own .flake8 config file is configured like this.
-If you're curious about the reasoning behind B950, Bugbear's documentation
-explains it.  The tl;dr is "it's like highway speed limits, we won't
-bother you if you overdo it by a few km/h".
-
-
-### Empty lines
-
-*Black* avoids spurious vertical whitespace.  This is in the spirit of
-PEP 8 which says that in-function vertical whitespace should only be
-used sparingly.
-
-*Black* will allow single empty lines inside functions, and single and
-double empty lines on module level left by the original editors, except
-when they're within parenthesized expressions.  Since such expressions
-are always reformatted to fit minimal space, this whitespace is lost.
-
-It will also insert proper spacing before and after function definitions.
-It's one line before and after inner functions and two lines before and
-after module-level functions.  *Black* will not put empty lines between
-function/class definitions and standalone comments that immediately precede
-the given function/class.
+You can even configure `git` to automatically ignore revisions listed in a file on every
+call to `git blame`.

 
 

+```console
+$ git config blame.ignoreRevsFile .git-blame-ignore-revs
+```

 
 

-### Trailing commas
+**The one caveat is that GitHub and GitLab do not yet support ignoring revisions using
+their native UI of blame.** So blame information will be cluttered with a reformatting
+commit on those platforms. (If you'd like this feature, there's an open issue for
+[GitLab](https://gitlab.com/gitlab-org/gitlab/-/issues/31423) and please let GitHub
+know!)

 
 

-*Black* will add trailing commas to expressions that are split
-by comma where each element is on its own line.  This includes function
-signatures.
+### NOTE: This is a beta product

 
 

-Unnecessary trailing commas are removed if an expression fits in one
-line.  This makes it 1% more likely that your line won't exceed the
-allotted line length limit.  Moreover, in this scenario, if you added
-another argument to your call, you'd probably fit it in the same line
-anyway.  That doesn't make diffs any larger.
-
-One exception to removing trailing commas is tuple expressions with
-just one element.  In this case *Black* won't touch the single trailing
-comma as this would unexpectedly change the underlying data type.  Note
-that this is also the case when commas are used while indexing.  This is
-a tuple in disguise: ```numpy_array[3, ]```.
-
-One exception to adding trailing commas is function signatures
-containing `*`, `*args`, or `**kwargs`.  In this case a trailing comma
-is only safe to use on Python 3.6.  *Black* will detect if your file is
-already 3.6+ only and use trailing commas in this situation.  If you
-wonder how it knows, it looks for f-strings and existing use of trailing
-commas in function signatures that have stars in them.  In other words,
-if you'd like a trailing comma in this situation and *Black* didn't
-recognize it was safe to do so, put it there manually and *Black* will
-keep it.
-
-
-### Strings
-
-*Black* prefers double quotes (`"` and `"""`) over single quotes (`'`
-and `'''`).  It will replace the latter with the former as long as it
-does not result in more backslash escapes than before.
-
-*Black* also standardizes string prefixes, making them always lowercase.
-On top of that, if your code is already Python 3.6+ only or it's using
-the `unicode_literals` future import, *Black* will remove `u` from the
-string prefix as it is meaningless in those scenarios.
-
-The main reason to standardize on a single form of quotes is aesthetics.
-Having one kind of quotes everywhere reduces reader distraction.
-It will also enable a future version of *Black* to merge consecutive
-string literals that ended up on the same line (see
-[#26](https://github.com/ambv/black/issues/26) for details).
-
-Why settle on double quotes?  They anticipate apostrophes in English
-text.  They match the docstring standard described in PEP 257.  An
-empty string in double quotes (`""`) is impossible to confuse with
-a one double-quote regardless of fonts and syntax highlighting used.
-On top of this, double quotes for strings are consistent with C which
-Python interacts a lot with.
-
-On certain keyboard layouts like US English, typing single quotes is
-a bit easier than double quotes.  The latter requires use of the Shift
-key.  My recommendation here is to keep using whatever is faster to type
-and let *Black* handle the transformation.
-
-
-### Line Breaks & Binary Operators
-
-*Black* will break a line before a binary operator when splitting a block
-of code over multiple lines. This is so that *Black* is compliant with the
-recent changes in the [PEP 8](https://www.python.org/dev/peps/pep-0008/#should-a-line-break-before-or-after-a-binary-operator)
-style guide, which emphasizes that this approach improves readability.
-
-This behaviour may raise ``W503 line break before binary operator`` warnings in
-style guide enforcement tools like Flake8. Since ``W503`` is not PEP 8 compliant,
-you should tell Flake8 to ignore these warnings.
-
-
-### Slices
-
-PEP 8 [recommends](https://www.python.org/dev/peps/pep-0008/#whitespace-in-expressions-and-statements)
-to treat ``:`` in slices as a binary operator with the lowest priority, and to
-leave an equal amount of space on either side, except if a parameter is omitted
-(e.g. ``ham[1 + 1 :]``). It also states that for extended slices, both ``:``
-operators have to have the same amount of spacing, except if a parameter is
-omitted (``ham[1 + 1 ::]``). *Black* enforces these rules consistently.
-
-This behaviour may raise ``E203 whitespace before ':'`` warnings in style guide
-enforcement tools like Flake8. Since ``E203`` is not PEP 8 compliant, you should
-tell Flake8 to ignore these warnings.
-
-
-### Parentheses
-
-Some parentheses are optional in the Python grammar.  Any expression can
-be wrapped in a pair of parentheses to form an atom.  There are a few
-interesting cases:
-
-- `if (...):`
-- `while (...):`
-- `for (...) in (...):`
-- `assert (...), (...)`
-- `from X import (...)`
-- assignments like:
-  - `target = (...)`
-  - `target: type = (...)`
-  - `some, *un, packing = (...)`
-  - `augmented += (...)`
-
-In those cases, parentheses are removed when the entire statement fits
-in one line, or if the inner expression doesn't have any delimiters to
-further split on.  If there is only a single delimiter and the expression
-starts or ends with a bracket, the parenthesis can also be successfully
-omitted since the existing bracket pair will organize the expression
-neatly anyway.  Otherwise, the parentheses are added.
-
-Please note that *Black* does not add or remove any additional nested
-parentheses that you might want to have for clarity or further
-code organization.  For example those parentheses are not going to be
-removed:
-```py3
-return not (this or that)
-decision = (maybe.this() and values > 0) or (maybe.that() and values < 0)
+_Black_ is already [successfully used](#used-by) by many projects, small and big. It
+also sports a decent test suite. However, it is still very new. Things will probably be
+wonky for a while. This is made explicit by the "Beta" trove classifier, as well as by
+the "b" in the version number. What this means for you is that **until the formatter
+becomes stable, you should expect some formatting to change in the future**. That being
+said, no drastic stylistic changes are planned, mostly responses to bug reports.
+
+Also, as a temporary safety measure, _Black_ will check that the reformatted code still
+produces a valid AST that is equivalent to the original. This slows it down. If you're
+feeling confident, use `--fast`.
+
+## The _Black_ code style
+
+_Black_ is a PEP 8 compliant opinionated formatter. _Black_ reformats entire files in
+place. It is not configurable. It doesn't take previous formatting into account. Your
+main option of configuring _Black_ is that it doesn't reformat blocks that start with
+`# fmt: off` and end with `# fmt: on`. `# fmt: on/off` have to be on the same level of
+indentation. To learn more about _Black_'s opinions, to go
+[the_black_code_style](https://github.com/psf/black/blob/master/docs/the_black_code_style.md).
+
+Please refer to this document before submitting an issue. What seems like a bug might be
+intended behaviour.
+
+## Pragmatism
+
+Early versions of _Black_ used to be absolutist in some respects. They took after its
+initial author. This was fine at the time as it made the implementation simpler and
+there were not many users anyway. Not many edge cases were reported. As a mature tool,
+_Black_ does make some exceptions to rules it otherwise holds. This
+[section](https://github.com/psf/black/blob/master/docs/the_black_code_style.md#pragmatism)
+of `the_black_code_style` describes what those exceptions are and why this is the case.
+
+Please refer to this document before submitting an issue just like with the document
+above. What seems like a bug might be intended behaviour.
+
+## pyproject.toml
+
+_Black_ is able to read project-specific default values for its command line options
+from a `pyproject.toml` file. This is especially useful for specifying custom
+`--include` and `--exclude` patterns for your project.
+
+**Pro-tip**: If you're asking yourself "Do I need to configure anything?" the answer is
+"No". _Black_ is all about sensible defaults.
+
+### What on Earth is a `pyproject.toml` file?
+
+[PEP 518](https://www.python.org/dev/peps/pep-0518/) defines `pyproject.toml` as a
+configuration file to store build system requirements for Python projects. With the help
+of tools like [Poetry](https://python-poetry.org/) or
+[Flit](https://flit.readthedocs.io/en/latest/) it can fully replace the need for
+`setup.py` and `setup.cfg` files.
+
+### Where _Black_ looks for the file
+
+By default _Black_ looks for `pyproject.toml` starting from the common base directory of
+all files and directories passed on the command line. If it's not there, it looks in
+parent directories. It stops looking when it finds the file, or a `.git` directory, or a
+`.hg` directory, or the root of the file system, whichever comes first.
+
+If you're formatting standard input, _Black_ will look for configuration starting from
+the current working directory.
+
+You can also explicitly specify the path to a particular file that you want with
+`--config`. In this situation _Black_ will not look for any other file.
+
+If you're running with `--verbose`, you will see a blue message if a file was found and
+used.
+
+Please note `blackd` will not use `pyproject.toml` configuration.
+
+### Configuration format
+
+As the file extension suggests, `pyproject.toml` is a
+[TOML](https://github.com/toml-lang/toml) file. It contains separate sections for
+different tools. _Black_ is using the `[tool.black]` section. The option keys are the
+same as long names of options on the command line.
+
+Note that you have to use single-quoted strings in TOML for regular expressions. It's
+the equivalent of r-strings in Python. Multiline strings are treated as verbose regular
+expressions by Black. Use `[ ]` to denote a significant space character.
+
+<details>
+<summary>Example `pyproject.toml`</summary>
+
+```toml
+[tool.black]
+line-length = 88
+target-version = ['py37']
+include = '\.pyi?$'
+exclude = '''
+
+(
+  /(
+      \.eggs         # exclude a few common directories in the
+    | \.git          # root of the project
+    | \.hg
+    | \.mypy_cache
+    | \.tox
+    | \.venv
+    | _build
+    | buck-out
+    | build
+    | dist
+  )/
+  | foo.py           # also separately exclude a file named foo.py in
+                     # the root of the project
+)
+'''

 ```
 
 ```
 

+</details>

 
 

-### Call chains
-
-Some popular APIs, like ORMs, use call chaining.  This API style is known
-as a [fluent interface](https://en.wikipedia.org/wiki/Fluent_interface).
-*Black* formats those treating dots that follow a call or an indexing
-operation like a very low priority delimiter.  It's easier to show the
-behavior than to explain it.  Look at the example:
-```py3
-def example(session):
-    result = (
-        session.query(models.Customer.id)
-        .filter(
-            models.Customer.account_id == account_id,
-            models.Customer.email == email_address,
-        )
-        .order_by(models.Customer.id.asc())
-        .all()
-    )
-```
-
+### Lookup hierarchy

 
 

-### Typing stub files
-
-PEP 484 describes the syntax for type hints in Python.  One of the
-use cases for typing is providing type annotations for modules which
-cannot contain them directly (they might be written in C, or they might
-be third-party, or their implementation may be overly dynamic, and so on).
-
-To solve this, [stub files with the `.pyi` file
-extension](https://www.python.org/dev/peps/pep-0484/#stub-files) can be
-used to describe typing information for an external module.  Those stub
-files omit the implementation of classes and functions they
-describe, instead they only contain the structure of the file (listing
-globals, functions, and classes with their members).  The recommended
-code style for those files is more terse than PEP 8:
-
-* prefer `...` on the same line as the class/function signature;
-* avoid vertical whitespace between consecutive module-level functions,
-  names, or methods and fields within a single class;
-* use a single blank line between top-level class definitions, or none
-  if the classes are very small.
-
-*Black* enforces the above rules.  There are additional guidelines for
-formatting `.pyi` file that are not enforced yet but might be in
-a future version of the formatter:
-
-* all function bodies should be empty (contain `...` instead of the body);
-* do not use docstrings;
-* prefer `...` over `pass`;
-* for arguments with a default, use `...` instead of the actual default;
-* avoid using string literals in type annotations, stub files support
-  forward references natively (like Python 3.7 code with `from __future__
-  import annotations`);
-* use variable annotations instead of type comments, even for stubs that
-  target older versions of Python;
-* for arguments that default to `None`, use `Optional[]` explicitly;
-* use `float` instead of `Union[int, float]`.
+Command-line options have defaults that you can see in `--help`. A `pyproject.toml` can
+override those defaults. Finally, options provided by the user on the command line
+override both.

 
 

+_Black_ will only ever use one `pyproject.toml` file during an entire run. It doesn't
+look for multiple files, and doesn't compose configuration from different levels of the
+file hierarchy.

+## Version control integration

 
 

-or with [Vundle](https://github.com/VundleVim/Vundle.vim):
+Use [pre-commit](https://pre-commit.com/). Once you
+[have it installed](https://pre-commit.com/#install), add this to the
+`.pre-commit-config.yaml` in your repository:

 
 

+```yaml
+repos:
+  - repo: https://github.com/psf/black
+    rev: stable
+    hooks:
+      - id: black
+        language_version: python3.6

 ```
 ```

-Plugin 'ambv/black'
-```
-
-or you can copy the plugin from [plugin/black.vim](https://github.com/ambv/black/tree/master/plugin/black.vim).
-Let me know if this requires any changes to work with Vim 8's builtin
-`packadd`, or Pathogen, and so on.
-
-This plugin **requires Vim 7.0+ built with Python 3.6+ support**.  It
-needs Python 3.6 to be able to run *Black* inside the Vim process which
-is much faster than calling an external command.
-
-On first run, the plugin creates its own virtualenv using the right
-Python version and automatically installs *Black*. You can upgrade it later
-by calling `:BlackUpgrade` and restarting Vim.
-
-If you need to do anything special to make your virtualenv work and
-install *Black* (for example you want to run a version from master),
-create a virtualenv manually and point `g:black_virtualenv` to it.
-The plugin will use it.
-
-**How to get Vim with Python 3.6?**
-On Ubuntu 17.10 Vim comes with Python 3.6 by default.
-On macOS with HomeBrew run: `brew install vim --with-python3`.
-When building Vim from source, use:
-`./configure --enable-python3interp=yes`. There's many guides online how
-to do this.
-

 
 

-### Visual Studio Code
-
-Use [joslarson.black-vscode](https://marketplace.visualstudio.com/items?itemName=joslarson.black-vscode).
-
-
-### SublimeText 3
-
-Use [sublack plugin](https://github.com/jgirardet/sublack).
-
-
-### IPython Notebook Magic
+Then run `pre-commit install` and you're ready to go.

 
 

-Use [blackcellmagic](https://github.com/csurfer/blackcellmagic).
+Avoid using `args` in the hook. Instead, store necessary configuration in
+`pyproject.toml` so that editors and command-line usage of Black all behave consistently
+for your project. See _Black_'s own
+[pyproject.toml](https://github.com/psf/black/blob/master/pyproject.toml) for an
+example.

 
 

+If you're already using Python 3.7, switch the `language_version` accordingly. Finally,
+`stable` is a branch that tracks the latest release on PyPI. If you'd rather run on
+master, this is also an option.

 
 

-### Other editors
+## GitHub Actions

 
 

-Atom/Nuclide integration is planned by the author, others will
-require external contributions.
+Create a file named `.github/workflows/black.yml` inside your repository with:

 
 

-Patches welcome! ✨ 🍰 ✨
+```yaml

-Any tool that can pipe code through *Black* using its stdio mode (just
-[use `-` as the file name](http://www.tldp.org/LDP/abs/html/special-chars.html#DASHREF2)).
-The formatted code will be returned on stdout (unless `--check` was
-passed).  *Black* will still emit messages on stderr but that shouldn't
-affect your use case.
+on: [push, pull_request]

 
 

-This can be used for example with PyCharm's [File Watchers](https://www.jetbrains.com/help/pycharm/file-watchers.html).

+## Ignoring unmodified files

 
 

-## Version control integration
+_Black_ remembers files it has already formatted, unless the `--diff` flag is used or
+code is passed via standard input. This information is stored per-user. The exact
+location of the file depends on the _Black_ version and the system on which _Black_ is
+run. The file is non-portable. The standard location on common operating systems is:

+`file-mode` is an int flag that determines whether the file was formatted as 3.6+ only,
+as .pyi, and whether string normalization was omitted.

 
 

+To override the location of these files on macOS or Linux, set the environment variable
+`XDG_CACHE_HOME` to your preferred location. For example, if you want to put the cache
+in the directory you're running _Black_ from, set `XDG_CACHE_HOME=.cache`. _Black_ will
+then write the above files to `.cache/black/<version>/`.

-* math operators now use their respective priorities for delimiting multiline
-  expressions (#148)
+More details can be found in
+[CONTRIBUTING](https://github.com/psf/black/blob/master/CONTRIBUTING.md).

 
 

-* optional parentheses are now omitted on expressions that start or end
-  with a bracket and only contain a single operator (#177)
+## Change log

 
 

-* empty parentheses in a class definition are now removed (#145, #180)
-
-* string prefixes are now standardized to lowercase and `u` is removed
-  on Python 3.6+ only code and Python 2.7+ code with the `unicode_literals`
-  future import (#188, #198, #199)
-
-* typing stub files (`.pyi`) are now formatted in a style that is consistent
-  with PEP 484 (#207, #210)
-
-* progress when reformatting many files is now reported incrementally
-
-* fixed trailers (content with brackets) being unnecessarily exploded
-  into their own lines after a dedented closing bracket (#119)
-
-* fixed an invalid trailing comma sometimes left in imports (#185)
-
-* fixed non-deterministic formatting when multiple pairs of removable parentheses
-  were used (#183)
-
-* fixed multiline strings being unnecessarily wrapped in optional
-  parentheses in long assignments (#215)
-
-* fixed not splitting long from-imports with only a single name
-
-* fixed Python 3.6+ file discovery by also looking at function calls with
-  unpacking. This fixed non-deterministic formatting if trailing commas
-  where used both in function signatures with stars and function calls
-  with stars but the former would be reformatted to a single line.
-
-* fixed crash on dealing with optional parentheses (#193)
-
-* fixed "is", "is not", "in", and "not in" not considered operators for
-  splitting purposes
-
-* fixed crash when dead symlinks where encountered
-
-
-### 18.4a4
-
-* don't populate the cache on `--check` (#175)
-
-
-### 18.4a3
-
-* added a "cache"; files already reformatted that haven't changed on disk
-  won't be reformatted again (#109)
-
-* `--check` and `--diff` are no longer mutually exclusive (#149)
-
-* generalized star expression handling, including double stars; this
-  fixes multiplication making expressions "unsafe" for trailing commas (#132)
-
-* Black no longer enforces putting empty lines behind control flow statements
-  (#90)
-
-* Black now splits imports like "Mode 3 + trailing comma" of isort (#127)
-
-* fixed comment indentation when a standalone comment closes a block (#16, #32)
-
-* fixed standalone comments receiving extra empty lines if immediately preceding
-  a class, def, or decorator (#56, #154)
-
-* fixed `--diff` not showing entire path (#130)
-
-* fixed parsing of complex expressions after star and double stars in
-  function calls (#2)
-
-* fixed invalid splitting on comma in lambda arguments (#133)
-
-* fixed missing splits of ternary expressions (#141)
-
-
-### 18.4a2
-
-* fixed parsing of unaligned standalone comments (#99, #112)
-
-* fixed placement of dictionary unpacking inside dictionary literals (#111)
-
-* Vim plugin now works on Windows, too
-
-* fixed unstable formatting when encountering unnecessarily escaped quotes
-  in a string (#120)
-
-
-### 18.4a1
-
-* added `--quiet` (#78)
-
-* added automatic parentheses management (#4)
-
-* added [pre-commit](https://pre-commit.com) integration (#103, #104)
-
-* fixed reporting on `--check` with multiple files (#101, #102)
-
-* fixed removing backslash escapes from raw strings (#100, #105)
-
-
-### 18.4a0
-
-* added `--diff` (#87)
-
-* add line breaks before all delimiters, except in cases like commas, to
-  better comply with PEP 8 (#73)
-
-* standardize string literals to use double quotes (almost) everywhere
-  (#75)
-
-* fixed handling of standalone comments within nested bracketed
-  expressions; Black will no longer produce super long lines or put all
-  standalone comments at the end of the expression (#22)
-
-* fixed 18.3a4 regression: don't crash and burn on empty lines with
-  trailing whitespace (#80)
-
-* fixed 18.3a4 regression: `# yapf: disable` usage as trailing comment
-  would cause Black to not emit the rest of the file (#95)
-
-* when CTRL+C is pressed while formatting many files, Black no longer
-  freaks out with a flurry of asyncio-related exceptions
-
-* only allow up to two empty lines on module level and only single empty
-  lines within functions (#74)
-
-
-### 18.3a4
-
-* `# fmt: off` and `# fmt: on` are implemented (#5)
-
-* automatic detection of deprecated Python 2 forms of print statements
-  and exec statements in the formatted file (#49)
-
-* use proper spaces for complex expressions in default values of typed
-  function arguments (#60)
-
-* only return exit code 1 when --check is used (#50)
-
-* don't remove single trailing commas from square bracket indexing
-  (#59)
-
-* don't omit whitespace if the previous factor leaf wasn't a math
-  operator (#55)
-
-* omit extra space in kwarg unpacking if it's the first argument (#46)
-
-* omit extra space in [Sphinx auto-attribute comments](http://www.sphinx-doc.org/en/stable/ext/autodoc.html#directive-autoattribute)
-  (#68)
-
-
-### 18.3a3
-
-* don't remove single empty lines outside of bracketed expressions
-  (#19)
-
-* added ability to pipe formatting from stdin to stdin (#25)
-
-* restored ability to format code with legacy usage of `async` as
-  a name (#20, #42)
-
-* even better handling of numpy-style array indexing (#33, again)
-
-
-### 18.3a2
-
-* changed positioning of binary operators to occur at beginning of lines
-  instead of at the end, following [a recent change to PEP8](https://github.com/python/peps/commit/c59c4376ad233a62ca4b3a6060c81368bd21e85b)
-  (#21)
-
-* ignore empty bracket pairs while splitting. This avoids very weirdly
-  looking formattings (#34, #35)
-
-* remove a trailing comma if there is a single argument to a call
-
-* if top level functions were separated by a comment, don't put four
-  empty lines after the upper function

-  into last statement if it was a simple statement (#18, #28)
-
-* fixed missing space in numpy-style array indexing (#33)
-
-* fixed spurious space after star-based unary expressions (#31)
-
-
-### 18.3a1
-
-* added `--check`
-
-* only put trailing commas in function signatures and calls if it's
-  safe to do so. If the file is Python 3.6+ it's always safe, otherwise
-  only safe if there are no `*args` or `**kwargs` used in the signature
-  or call. (#8)
-
-* fixed invalid spacing of dots in relative imports (#6, #13)
-
-* fixed invalid splitting after comma on unpacked variables in for-loops
