## PyCharm/IntelliJ IDEA
+There are three different ways you can use _Black_ from PyCharm:
+
+1. As local server using the BlackConnect plugin
+1. As external tool
+1. As file watcher
+
+The first option is the simplest to set up and formats the fastest (by spinning up
+{doc}`Black's HTTP server </usage_and_configuration/black_as_a_server>`, avoiding the
+startup cost on subsequent formats), but if you would prefer to not install a
+third-party plugin or blackd's extra dependencies, the other two are also great options.
+
+### As local server
+
1. Install _Black_ with the `d` extra.
```console
- In `Trigger Settings` section of plugin configuration check
`Trigger when saving changed files`.
+### As external tool
+
+1. Install `black`.
+
+ ```console
+ $ pip install black
+ ```
+
+1. Locate your `black` installation folder.
+
+ On macOS / Linux / BSD:
+
+ ```console
+ $ which black
+ /usr/local/bin/black # possible location
+ ```
+
+ On Windows:
+
+ ```console
+ $ where black
+ %LocalAppData%\Programs\Python\Python36-32\Scripts\black.exe # possible location
+ ```
+
+ Note that if you are using a virtual environment detected by PyCharm, this is an
+ unneeded step. In this case the path to `black` is `$PyInterpreterDirectory$/black`.
+
+1. Open External tools in PyCharm/IntelliJ IDEA
+
+ On macOS:
+
+ `PyCharm -> Preferences -> Tools -> External Tools`
+
+ On Windows / Linux / BSD:
+
+ `File -> Settings -> Tools -> External Tools`
+
+1. Click the + icon to add a new external tool with the following values:
+
+ - Name: Black
+ - Description: Black is the uncompromising Python code formatter.
+ - Program: \<install_location_from_step_2>
+ - Arguments: `"$FilePath$"`
+
+1. Format the currently opened file by selecting `Tools -> External Tools -> black`.
+
+ - Alternatively, you can set a keyboard shortcut by navigating to
+ `Preferences or Settings -> Keymap -> External Tools -> External Tools - Black`.
+
+### As file watcher
+
+1. Install `black`.
+
+ ```console
+ $ pip install black
+ ```
+
+1. Locate your `black` installation folder.
+
+ On macOS / Linux / BSD:
+
+ ```console
+ $ which black
+ /usr/local/bin/black # possible location
+ ```
+
+ On Windows:
+
+ ```console
+ $ where black
+ %LocalAppData%\Programs\Python\Python36-32\Scripts\black.exe # possible location
+ ```
+
+ Note that if you are using a virtual environment detected by PyCharm, this is an
+ unneeded step. In this case the path to `black` is `$PyInterpreterDirectory$/black`.
+
+1. Make sure you have the
+ [File Watchers](https://plugins.jetbrains.com/plugin/7177-file-watchers) plugin
+ installed.
+1. Go to `Preferences or Settings -> Tools -> File Watchers` and click `+` to add a new
+ watcher:
+ - Name: Black
+ - File type: Python
+ - Scope: Project Files
+ - Program: \<install_location_from_step_2>
+ - Arguments: `$FilePath$`
+ - Output paths to refresh: `$FilePath$`
+ - Working directory: `$ProjectFileDir$`
+
+- In Advanced Options
+ - Uncheck "Auto-save edited files to trigger the watcher"
+ - Uncheck "Trigger the watcher on external changes"
+
## Wing IDE
Wing IDE supports `black` via **Preference Settings** for system wide settings and
- you can optionally pass `target_version=<version>` with the same values as in the
command line.
- `:BlackUpgrade` to upgrade _Black_ inside the virtualenv;
-- `:BlackVersion` to get the current version of _Black_ inside the virtualenv.
+- `:BlackVersion` to get the current version of _Black_ in use.
Configuration:
- `g:black_fast` (defaults to `0`)
- `g:black_linelength` (defaults to `88`)
- `g:black_skip_string_normalization` (defaults to `0`)
+- `g:black_skip_magic_trailing_comma` (defaults to `0`)
- `g:black_virtualenv` (defaults to `~/.vim/black` or `~/.local/share/nvim/black`)
+- `g:black_use_virtualenv` (defaults to `1`)
+- `g:black_target_version` (defaults to `""`)
- `g:black_quiet` (defaults to `0`)
- `g:black_preview` (defaults to `0`)
+#### Installation
+
+This plugin **requires Vim 7.0+ built with Python 3.7+ support**. It needs Python 3.7 to
+be able to run _Black_ inside the Vim process which is much faster than calling an
+external command.
+
+##### `vim-plug`
+
To install with [vim-plug](https://github.com/junegunn/vim-plug):
+_Black_'s `stable` branch tracks official version updates, and can be used to simply
+follow the most recent stable version.
+
```
Plug 'psf/black', { 'branch': 'stable' }
```
+Another option which is a bit more explicit and offers more control is to use
+`vim-plug`'s `tag` option with a shell wildcard. This will resolve to the latest tag
+which matches the given pattern.
+
+The following matches all stable versions (see the
+[Release Process](../contributing/release_process.md) section for documentation of
+version scheme used by Black):
+
+```
+Plug 'psf/black', { 'tag': '*.*.*' }
+```
+
+and the following demonstrates pinning to a specific year's stable style (2022 in this
+case):
+
+```
+Plug 'psf/black', { 'tag': '22.*.*' }
+```
+
+##### Vundle
+
or with [Vundle](https://github.com/VundleVim/Vundle.vim):
```
$ git checkout origin/stable -b stable
```
+##### Arch Linux
+
+On Arch Linux, the plugin is shipped with the
+[`python-black`](https://archlinux.org/packages/community/any/python-black/) package, so
+you can start using it in Vim after install with no additional setup.
+
+##### Vim 8 Native Plugin Management
+
or you can copy the plugin files from
[plugin/black.vim](https://github.com/psf/black/blob/stable/plugin/black.vim) and
[autoload/black.vim](https://github.com/psf/black/blob/stable/autoload/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 3.7+ support**. It needs Python 3.7 to
-be able to run _Black_ inside the Vim process which is much faster than calling an
-external command.
+#### Usage
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
example you want to run a version from main), create a virtualenv manually and point
`g:black_virtualenv` to it. The plugin will use it.
+If you would prefer to use the system installation of _Black_ rather than a virtualenv,
+then add this to your vimrc:
+
+```
+let g:black_use_virtualenv = 0
+```
+
+Note that the `:BlackUpgrade` command is only usable and useful with a virtualenv, so
+when the virtualenv is not in use, `:BlackUpgrade` is disabled. If you need to upgrade
+the system installation of _Black_, then use your system package manager or pip--
+whatever tool you used to install _Black_ originally.
+
To run _Black_ on save, add the following lines to `.vimrc` or `init.vim`:
```
nnoremap <F9> :Black<CR>
```
-**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`. 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 "<string>", line 63, in <module>
- File "/home/gui/.vim/black/lib/python3.7/site-packages/black.py", line 45, in <module>
- from typed_ast import ast3, ast27
- File "/home/gui/.vim/black/lib/python3.7/site-packages/typed_ast/ast3.py", line 40, in <module>
- 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` 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 package that causes problems is:
-
-- [typed-ast](https://pypi.org/project/typed-ast/)
-
-Now remove those two packages:
-
-```console
-$ pip uninstall typed-ast -y
-```
-
-And now you can install them with:
-
-```console
-$ pip install --no-binary :all: 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 typed-ast
-```
