- ```
+ On Windows / Linux / BSD:
- 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`.
+ `File -> Settings -> Tools -> BlackConnect`
-1. Open External tools in PyCharm/IntelliJ IDEA
+1. In `Local Instance (shared between projects)` section:
- On macOS:
+ 1. Check `Start local blackd instance when plugin loads`.
+ 1. Press the `Detect` button near `Path` input. The plugin should detect the `blackd`

- `PyCharm -> Preferences -> Tools -> External Tools`
+1. In `Trigger Settings` section check `Trigger on code reformat` to enable code
+ reformatting with _Black_.
- On Windows / Linux / BSD:

- - Description: Black is the uncompromising Python code formatter.
- - Program: \<install_location_from_step_2>
- - Arguments: `"$FilePath$"`
+## Wing IDE
-1. Format the currently opened file by selecting `Tools -> External Tools -> black`.
+Wing IDE supports `black` via **Preference Settings** for system wide settings and
+**Project Properties** for per-project or workspace specific settings, as explained in
+the Wing documentation on
+[Auto-Reformatting](https://wingware.com/doc/edit/auto-reformatting). The detailed
+procedure is:
- - Alternatively, you can set a keyboard shortcut by navigating to
- `Preferences or Settings -> Keymap -> External Tools -> External Tools - Black`.
+### Prerequistes
-1. Optionally, run _Black_ on every file save:
+- Wing IDE version 8.0+
- 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: `$ProjectFileDir$`
+- Install `black`.
- - In Advanced Options
- - Uncheck "Auto-save edited files to trigger the watcher"
- - Uncheck "Trigger the watcher on external changes"
+ ```console
+ $ pip install black
+ ```
-## Wing IDE
+- Make sure it runs from the command line, e.g.
-Wing supports black via the OS Commands tool, as explained in the Wing documentation on
-[pep8 formatting](https://wingware.com/doc/edit/pep8). The detailed procedure is:
+ ```console
+ $ black --help
+ ```
-1. Install `black`.
+### Preference Settings
- ```console
- $ pip install black
- ```
+If you want Wing IDE to always reformat with `black` for every project, follow these
+steps:
-1. Make sure it runs from the command line, e.g.
+1. In menubar navigate to `Edit -> Preferences -> Editor -> Reformatting`.
- ```console
- $ black --help
- ```
+1. Set **Auto-Reformat** from `disable` (default) to `Line after edit` or
+ `Whole files before save`.
+
+1. Set **Reformatter** from `PEP8` (default) to `Black`.
-1. In Wing IDE, activate the **OS Commands** panel and define the command **black** to
- execute black on the currently selected file:
+### Project Properties
- - Use the Tools -> OS Commands menu selection
- - click on **+** in **OS Commands** -> New: Command line..
- - Title: black
- - Command Line: black %s
- - I/O Encoding: Use Default
- - Key Binding: F1
- - [x] Raise OS Commands when executed
- - [x] Auto-save files before execution
- - [x] Line mode
+If you want to just reformat for a specific project and not intervene with Wing IDE
+global setting, follow these steps:
-1. Select a file in the editor and press **F1** , or whatever key binding you selected
- in step 3, to reformat the file.
+1. In menubar navigate to `Project -> Project Properties -> Options`.
+
+1. Set **Auto-Reformat** from `Use Preferences setting` (default) to `Line after edit`
+ or `Whole files before save`.
+
+1. Set **Reformatter** from `Use Preferences setting` (default) to `Black`.
## Vim
Commands and shortcuts:
- `:Black` to format the entire file (ranges not supported);
+ - 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.
- `g:black_skip_string_normalization` (defaults to `0`)
- `g:black_virtualenv` (defaults to `~/.vim/black` or `~/.local/share/nvim/black`)
- `g:black_quiet` (defaults to `0`)
+- `g:black_preview` (defaults to `0`)
To install with [vim-plug](https://github.com/junegunn/vim-plug):

Pathogen, and so on.

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.
-To run _Black_ on save, add the following line to `.vimrc` or `init.vim`:

To run _Black_ on a key press (e.g. F9 below), add this:

```
-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.

- [typed-ast](https://pypi.org/project/typed-ast/)
Now remove those two packages:

+$ pip uninstall typed-ast -y
```
And now you can install them with:
```console
-$ pip install --no-binary :all: regex typed-ast
+$ pip install --no-binary :all: typed-ast
```
The C extensions will be compiled and now Vim's Python environment will match. Note that
If you later want to update _Black_, you should do it like this:
```console
-$ pip install -U black --no-binary regex,typed-ast
+$ pip install -U black --no-binary typed-ast
```
