On macOS with Homebrew run: `brew install vim`. When building Vim from source, +use: `./configure --enable-python3interp=yes`. There's many guides online how to do +this. + +**I get an import error when using _Black_ from a virtual environment**: If you get an +error message like this: + +```text +Traceback (most recent call last): + File "", line 63, in + File "/home/gui/.vim/black/lib/python3.7/site-packages/black.py", line 45, in + from typed_ast import ast3, ast27 + File "/home/gui/.vim/black/lib/python3.7/site-packages/typed_ast/ast3.py", line 40, in + from typed_ast import _ast3 +ImportError: /home/gui/.vim/black/lib/python3.7/site-packages/typed_ast/_ast3.cpython-37m-x86_64-linux-gnu.so: undefined symbool: PyExc_KeyboardInterrupt +``` + +Then you need to install `typed_ast` and `regex` directly from the source code. The +error happens because `pip` will download [Python wheels](https://pythonwheels.com/) if +they are available. Python wheels are a new standard of distributing Python packages and +packages that have Cython and extensions written in C are already compiled, so the +installation is much more faster. The problem here is that somehow the Python +environment inside Vim does not match with those already compiled C extensions and these +kind of errors are the result. Luckily there is an easy fix: installing the packages +from the source code. + +The two packages that cause the problem are: + +- [regex](https://pypi.org/project/regex/) +- [typed-ast](https://pypi.org/project/typed-ast/) + +Now remove those two packages: + +```console +$ pip uninstall regex typed-ast -y +``` + +And now you can install them with: + +```console +$ pip install --no-binary :all: regex typed-ast +``` + +The C extensions will be compiled and now Vim's Python environment will match. Note that +you need to have the GCC compiler and the Python development files installed (on +Ubuntu/Debian do `sudo apt-get install build-essential python3-dev`). + +If you later want to update _Black_, you should do it like this: + +```console +$ pip install -U black --no-binary regex,typed-ast +``` + +## Visual Studio Code + +Use the +[Python extension](https://marketplace.visualstudio.com/items?itemName=ms-python.python) +([instructions](https://code.visualstudio.com/docs/python/editing#_formatting)). + +## SublimeText 3 + +Use [sublack plugin](https://github.com/jgirardet/sublack). + +## Jupyter Notebook Magic + +Use [blackcellmagic](https://github.com/csurfer/blackcellmagic). + +## Python Language Server + +If your editor supports the [Language Server Protocol](https://langserver.org/) (Atom, +Sublime Text, Visual Studio Code and many more), you can use the +[Python Language Server](https://github.com/palantir/python-language-server) with the +[pyls-black](https://github.com/rupert/pyls-black) plugin. + +## Atom/Nuclide + +Use [python-black](https://atom.io/packages/python-black). + +## Kakoune + +Add the following hook to your kakrc, then run _Black_ with `:format`. + +``` +hook global WinSetOption filetype=python %{ + set-option window formatcmd 'black -q -' +} +``` + +## Thonny + +Use [Thonny-black-code-format](https://github.com/Franccisco/thonny-black-code-format). + +## Other editors + +Other editors will require external contributions. + +Patches welcome! ✨ 🍰 ✨ + +Any tool that can pipe code through _Black_ using its stdio mode (just +[use `-` as the file name](https://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. + +This can be used for example with PyCharm's or IntelliJ's +[File Watchers](https://www.jetbrains.com/help/pycharm/file-watchers.html).
