It requires -Python 3.6.0+ to run but you can reformat Python 2 code with it, too. +_Black_ can be installed by running `pip install black`. It requires Python 3.7+ to run. +If you want to format Jupyter Notebooks, install with `pip install "black[jupyter]"`. +If you can't wait for the latest _hotness_ and want to install from GitHub, use: + +`pip install git+https://github.com/psf/black` ### Usage To get started right away with sensible defaults: -``` +```sh black {source_file_or_directory} ``` -### Command line options - -Black doesn't provide many options. You can list them by running -`black --help`: - -```text -black [OPTIONS] [SRC]... - -Options: - -l, --line-length INTEGER Where to wrap around. [default: 88] - --check Don't write the files back, just return the - status. Return code 0 means nothing would - change. Return code 1 means some files would be - reformatted. Return code 123 means there was an - internal error. - --diff Don't write the files back, just output a diff - for each file on stdout. - --fast / --safe If --fast given, skip temporary sanity checks. - [default: --safe] - --version Show the version and exit. - --help Show this message and exit. -``` - -*Black* is a well-behaved Unix-style command-line tool: -* 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 occured (or `--check` was - used). - - -### NOTE: This is an early pre-release - -*Black* can already successfully format itself and the standard library. -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 -"Alpha" trove classifier, as well as by the "a" 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**. - -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* 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. - - -### How *Black* wraps lines - -*Black* ignores previous formatting and applies uniform horizontal -and vertical whitespace to your code. The rules for horizontal -whitespace are pretty obvious and 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. - -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: - -l = [1, - 2, - 3, -] - -# out: - -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: - -l = [[n for n in list_bosses()], [n for n in list_employees()]] - -# out: - -l = [ - [n for n in list_bosses()], [n for n in list_employees()] -] -``` - -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: - ... -``` +You can run _Black_ as a package if running it as a script doesn't work: -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). - - -### 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 +```sh +python -m black {source_file_or_directory} ``` -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. One exception is control flow statements: *Black* will -always emit an extra empty line after ``return``, ``raise``, ``break``, -``continue``, and ``yield``. This is to make changes in control flow -more prominent to readers of your code. - -*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 put those empty lines also -between the function definition and any standalone comments that -immediately precede the given function. If you want to comment on the -entire function, use a docstring or put a leading comment in the function -body. - - -### Trailing commas +Further information can be found in our docs: -*Black* will add trailing commas to expressions that are split -by comma where each element is on its own line. This includes function -signatures. +- [Usage and Configuration](https://black.readthedocs.io/en/stable/usage_and_configuration/index.html) -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. +_Black_ is already [successfully used](https://github.com/psf/black#used-by) by many +projects, small and big. _Black_ has a comprehensive test suite, with efficient parallel +tests, and our own auto formatting and parallel Continuous Integration runner. Now that +we have become stable, you should not expect large formatting changes in the future. +Stylistic changes will mostly be responses to bug reports and support for new Python +syntax. For more information please refer to the +[The Black Code Style](https://black.readthedocs.io/en/stable/the_black_code_style/index.html). -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, ]```. +Also, as a safety measure which slows down processing, _Black_ will check that the +reformatted code still produces a valid AST that is effectively equivalent to the +original (see the +[Pragmatism](https://black.readthedocs.io/en/stable/the_black_code_style/current_style.html#ast-before-and-after-formatting) +section for details). If you're feeling confident, use `--fast`. -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. +## The _Black_ code style -### Strings +_Black_ is a PEP 8 compliant opinionated formatter. _Black_ reformats entire files in +place. Style configuration options are deliberately limited and rarely added. It doesn't +take previous formatting into account (see +[Pragmatism](https://black.readthedocs.io/en/stable/the_black_code_style/current_style.html#pragmatism) +for exceptions). -*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. +Our documentation covers the current _Black_ code style, but planned changes to it are +also documented. They're both worth taking a look: -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). +- [The _Black_ Code Style: Current style](https://black.readthedocs.io/en/stable/the_black_code_style/current_style.html) +- [The _Black_ Code Style: Future style](https://black.readthedocs.io/en/stable/the_black_code_style/future_style.html) -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. +Changes to the _Black_ code style are bound by the Stability Policy: -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. +- [The _Black_ Code Style: Stability Policy](https://black.readthedocs.io/en/stable/the_black_code_style/index.html#stability-policy) +Please refer to this document before submitting an issue. What seems like a bug might be +intended behaviour. -## Editor integration +### Pragmatism -### Emacs +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. -Use [proofit404/blacken](https://github.com/proofit404/blacken). +- [The _Black_ code style: Pragmatism](https://black.readthedocs.io/en/stable/the_black_code_style/current_style.html#pragmatism) +Please refer to this document before submitting an issue just like with the document +above.
