11 ## PyCharm/IntelliJ IDEA
19 1. Locate your `black` installation folder.
21 On macOS / Linux / BSD:
25 /usr/local/bin/black # possible location
32 %LocalAppData%\Programs\Python\Python36-32\Scripts\black.exe # possible location
35 Note that if you are using a virtual environment detected by PyCharm, this is an
36 unneeded step. In this case the path to `black` is `$PyInterpreterDirectory$/black`.
38 1. Open External tools in PyCharm/IntelliJ IDEA
42 `PyCharm -> Preferences -> Tools -> External Tools`
44 On Windows / Linux / BSD:
46 `File -> Settings -> Tools -> External Tools`
48 1. Click the + icon to add a new external tool with the following values:
51 - Description: Black is the uncompromising Python code formatter.
52 - Program: \<install_location_from_step_2>
53 - Arguments: `"$FilePath$"`
55 1. Format the currently opened file by selecting `Tools -> External Tools -> black`.
57 - Alternatively, you can set a keyboard shortcut by navigating to
58 `Preferences or Settings -> Keymap -> External Tools -> External Tools - Black`.
60 1. Optionally, run _Black_ on every file save:
62 1. Make sure you have the
63 [File Watchers](https://plugins.jetbrains.com/plugin/7177-file-watchers) plugin
65 1. Go to `Preferences or Settings -> Tools -> File Watchers` and click `+` to add a
69 - Scope: Project Files
70 - Program: \<install_location_from_step_2>
71 - Arguments: `$FilePath$`
72 - Output paths to refresh: `$FilePath$`
73 - Working directory: `$ProjectFileDir$`
76 - Uncheck "Auto-save edited files to trigger the watcher"
77 - Uncheck "Trigger the watcher on external changes"
81 Wing IDE supports `black` via **Preference Settings** for system wide settings and
82 **Project Properties** for per-project or workspace specific settings, as explained in
83 the Wing documentation on
84 [Auto-Reformatting](https://wingware.com/doc/edit/auto-reformatting). The detailed
89 - Wing IDE version 8.0+
97 - Make sure it runs from the command line, e.g.
103 ### Preference Settings
105 If you want Wing IDE to always reformat with `black` for every project, follow these
108 1. In menubar navigate to `Edit -> Preferences -> Editor -> Reformatting`.
110 1. Set **Auto-Reformat** from `disable` (default) to `Line after edit` or
111 `Whole files before save`.
113 1. Set **Reformatter** from `PEP8` (default) to `Black`.
115 ### Project Properties
117 If you want to just reformat for a specific project and not intervene with Wing IDE
118 global setting, follow these steps:
120 1. In menubar navigate to `Project -> Project Properties -> Options`.
122 1. Set **Auto-Reformat** from `Use Preferences setting` (default) to `Line after edit`
123 or `Whole files before save`.
125 1. Set **Reformatter** from `Use Preferences setting` (default) to `Black`.
131 Commands and shortcuts:
133 - `:Black` to format the entire file (ranges not supported);
134 - you can optionally pass `target_version=<version>` with the same values as in the
136 - `:BlackUpgrade` to upgrade _Black_ inside the virtualenv;
137 - `:BlackVersion` to get the current version of _Black_ inside the virtualenv.
141 - `g:black_fast` (defaults to `0`)
142 - `g:black_linelength` (defaults to `88`)
143 - `g:black_skip_string_normalization` (defaults to `0`)
144 - `g:black_virtualenv` (defaults to `~/.vim/black` or `~/.local/share/nvim/black`)
145 - `g:black_quiet` (defaults to `0`)
147 To install with [vim-plug](https://github.com/junegunn/vim-plug):
150 Plug 'psf/black', { 'branch': 'stable' }
153 or with [Vundle](https://github.com/VundleVim/Vundle.vim):
159 and execute the following in a terminal:
162 $ cd ~/.vim/bundle/black
163 $ git checkout origin/stable -b stable
166 or you can copy the plugin files from
167 [plugin/black.vim](https://github.com/psf/black/blob/stable/plugin/black.vim) and
168 [autoload/black.vim](https://github.com/psf/black/blob/stable/autoload/black.vim).
171 mkdir -p ~/.vim/pack/python/start/black/plugin
172 mkdir -p ~/.vim/pack/python/start/black/autoload
173 curl https://raw.githubusercontent.com/psf/black/stable/plugin/black.vim -o ~/.vim/pack/python/start/black/plugin/black.vim
174 curl https://raw.githubusercontent.com/psf/black/stable/autoload/black.vim -o ~/.vim/pack/python/start/black/autoload/black.vim
177 Let me know if this requires any changes to work with Vim 8's builtin `packadd`, or
180 This plugin **requires Vim 7.0+ built with Python 3.6+ support**. It needs Python 3.6 to
181 be able to run _Black_ inside the Vim process which is much faster than calling an
184 On first run, the plugin creates its own virtualenv using the right Python version and
185 automatically installs _Black_. You can upgrade it later by calling `:BlackUpgrade` and
188 If you need to do anything special to make your virtualenv work and install _Black_ (for
189 example you want to run a version from main), create a virtualenv manually and point
190 `g:black_virtualenv` to it. The plugin will use it.
192 To run _Black_ on save, add the following lines to `.vimrc` or `init.vim`:
195 augroup black_on_save
197 autocmd BufWritePre *.py Black
201 To run _Black_ on a key press (e.g. F9 below), add this:
204 nnoremap <F9> :Black<CR>
207 **How to get Vim with Python 3.6?** On Ubuntu 17.10 Vim comes with Python 3.6 by
208 default. On macOS with Homebrew run: `brew install vim`. When building Vim from source,
209 use: `./configure --enable-python3interp=yes`. There's many guides online how to do
212 **I get an import error when using _Black_ from a virtual environment**: If you get an
213 error message like this:
216 Traceback (most recent call last):
217 File "<string>", line 63, in <module>
218 File "/home/gui/.vim/black/lib/python3.7/site-packages/black.py", line 45, in <module>
219 from typed_ast import ast3, ast27
220 File "/home/gui/.vim/black/lib/python3.7/site-packages/typed_ast/ast3.py", line 40, in <module>
221 from typed_ast import _ast3
222 ImportError: /home/gui/.vim/black/lib/python3.7/site-packages/typed_ast/_ast3.cpython-37m-x86_64-linux-gnu.so: undefined symbool: PyExc_KeyboardInterrupt
225 Then you need to install `typed_ast` directly from the source code. The error happens
226 because `pip` will download [Python wheels](https://pythonwheels.com/) if they are
227 available. Python wheels are a new standard of distributing Python packages and packages
228 that have Cython and extensions written in C are already compiled, so the installation
229 is much more faster. The problem here is that somehow the Python environment inside Vim
230 does not match with those already compiled C extensions and these kind of errors are the
231 result. Luckily there is an easy fix: installing the packages from the source code.
233 The package that causes problems is:
235 - [typed-ast](https://pypi.org/project/typed-ast/)
237 Now remove those two packages:
240 $ pip uninstall typed-ast -y
243 And now you can install them with:
246 $ pip install --no-binary :all: typed-ast
249 The C extensions will be compiled and now Vim's Python environment will match. Note that
250 you need to have the GCC compiler and the Python development files installed (on
251 Ubuntu/Debian do `sudo apt-get install build-essential python3-dev`).
253 If you later want to update _Black_, you should do it like this:
256 $ pip install -U black --no-binary typed-ast
261 1. Install [`ale`](https://github.com/dense-analysis/ale)
265 1. Add this to your vimrc:
268 let g:ale_fixers = {}
269 let g:ale_fixers.python = ['black']
274 gedit is the default text editor of the GNOME, Unix like Operating Systems. Open gedit
281 1. `Go to edit > preferences > plugins`
282 1. Search for `external tools` and activate it.
283 1. In `Tools menu -> Manage external tools`
284 1. Add a new tool using `+` button.
285 1. Copy the below content to the code window.
289 Name=$GEDIT_CURRENT_DOCUMENT_NAME
293 - Set a keyboard shortcut if you like, Ex. `ctrl-B`
296 - Output: `Display in bottom pane` if you like.
297 - Change the name of the tool if you like.
299 Use your keyboard shortcut or `Tools -> External Tools` to use your new tool. When you
300 close and reopen your File, _Black_ will be done with its job.
302 ## Visual Studio Code
305 [Python extension](https://marketplace.visualstudio.com/items?itemName=ms-python.python)
306 ([instructions](https://code.visualstudio.com/docs/python/editing#_formatting)).
310 Use [sublack plugin](https://github.com/jgirardet/sublack).
314 If your editor supports the [Language Server Protocol](https://langserver.org/) (Atom,
315 Sublime Text, Visual Studio Code and many more), you can use the
316 [Python LSP Server](https://github.com/python-lsp/python-lsp-server) with the
317 [python-lsp-black](https://github.com/python-lsp/python-lsp-black) plugin.
321 Use [python-black](https://atom.io/packages/python-black) or
322 [formatters-python](https://atom.io/packages/formatters-python).
324 ## Gradle (the build tool)
326 Use the [Spotless](https://github.com/diffplug/spotless/tree/main/plugin-gradle) plugin.
330 Add the following hook to your kakrc, then run _Black_ with `:format`.
333 hook global WinSetOption filetype=python %{
334 set-option window formatcmd 'black -q -'
340 Use [Thonny-black-code-format](https://github.com/Franccisco/thonny-black-code-format).
