## 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"
+

-#### Troubleshooting
-
-**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
-```
