35 1. Press the `Detect` button near `Path` input. The plugin should detect the `blackd`
38 1. In `Trigger Settings` section check `Trigger on code reformat` to enable code
39 reformatting with _Black_.
41 1. Format the currently opened file by selecting `Code -> Reformat Code` or using a
44 1. Optionally, to run _Black_ on every file save:
46 - In `Trigger Settings` section of plugin configuration check
47 `Trigger when saving changed files`.
51 Wing IDE supports `black` via **Preference Settings** for system wide settings and
52 **Project Properties** for per-project or workspace specific settings, as explained in
53 the Wing documentation on
54 [Auto-Reformatting](https://wingware.com/doc/edit/auto-reformatting). The detailed
59 - Wing IDE version 8.0+
67 - Make sure it runs from the command line, e.g.
73 ### Preference Settings
75 If you want Wing IDE to always reformat with `black` for every project, follow these
78 1. In menubar navigate to `Edit -> Preferences -> Editor -> Reformatting`.
80 1. Set **Auto-Reformat** from `disable` (default) to `Line after edit` or
81 `Whole files before save`.
83 1. Set **Reformatter** from `PEP8` (default) to `Black`.
85 ### Project Properties
87 If you want to just reformat for a specific project and not intervene with Wing IDE
88 global setting, follow these steps:
90 1. In menubar navigate to `Project -> Project Properties -> Options`.
92 1. Set **Auto-Reformat** from `Use Preferences setting` (default) to `Line after edit`
93 or `Whole files before save`.
95 1. Set **Reformatter** from `Use Preferences setting` (default) to `Black`.
101 Commands and shortcuts:
103 - `:Black` to format the entire file (ranges not supported);
104 - you can optionally pass `target_version=<version>` with the same values as in the
106 - `:BlackUpgrade` to upgrade _Black_ inside the virtualenv;
107 - `:BlackVersion` to get the current version of _Black_ in use.
111 - `g:black_fast` (defaults to `0`)
112 - `g:black_linelength` (defaults to `88`)
113 - `g:black_skip_string_normalization` (defaults to `0`)
114 - `g:black_virtualenv` (defaults to `~/.vim/black` or `~/.local/share/nvim/black`)
115 - `g:black_quiet` (defaults to `0`)
116 - `g:black_preview` (defaults to `0`)
118 To install with [vim-plug](https://github.com/junegunn/vim-plug):
121 Plug 'psf/black', { 'branch': 'stable' }
124 or with [Vundle](https://github.com/VundleVim/Vundle.vim):
130 and execute the following in a terminal:
133 $ cd ~/.vim/bundle/black
134 $ git checkout origin/stable -b stable
137 or you can copy the plugin files from
138 [plugin/black.vim](https://github.com/psf/black/blob/stable/plugin/black.vim) and
139 [autoload/black.vim](https://github.com/psf/black/blob/stable/autoload/black.vim).
142 mkdir -p ~/.vim/pack/python/start/black/plugin
143 mkdir -p ~/.vim/pack/python/start/black/autoload
144 curl https://raw.githubusercontent.com/psf/black/stable/plugin/black.vim -o ~/.vim/pack/python/start/black/plugin/black.vim
145 curl https://raw.githubusercontent.com/psf/black/stable/autoload/black.vim -o ~/.vim/pack/python/start/black/autoload/black.vim
148 Let me know if this requires any changes to work with Vim 8's builtin `packadd`, or
151 This plugin **requires Vim 7.0+ built with Python 3.7+ support**. It needs Python 3.7 to
152 be able to run _Black_ inside the Vim process which is much faster than calling an
155 On first run, the plugin creates its own virtualenv using the right Python version and
156 automatically installs _Black_. You can upgrade it later by calling `:BlackUpgrade` and
159 If you need to do anything special to make your virtualenv work and install _Black_ (for
160 example you want to run a version from main), create a virtualenv manually and point
161 `g:black_virtualenv` to it. The plugin will use it.
163 If you would prefer to use the system installation of _Black_ rather than a virtualenv,
164 then add this to your vimrc:
167 let g:black_use_virtualenv = 0
170 Note that the `:BlackUpgrade` command is only usable and useful with a virtualenv, so
171 when the virtualenv is not in use, `:BlackUpgrade` is disabled. If you need to upgrade
172 the system installation of _Black_, then use your system package manager or pip--
173 whatever tool you used to install _Black_ originally.
175 To run _Black_ on save, add the following lines to `.vimrc` or `init.vim`:
178 augroup black_on_save
180 autocmd BufWritePre *.py Black
184 To run _Black_ on a key press (e.g. F9 below), add this:
187 nnoremap <F9> :Black<CR>
190 **How to get Vim with Python 3.6?** On Ubuntu 17.10 Vim comes with Python 3.6 by
191 default. On macOS with Homebrew run: `brew install vim`. When building Vim from source,
192 use: `./configure --enable-python3interp=yes`. There's many guides online how to do
195 **I get an import error when using _Black_ from a virtual environment**: If you get an
196 error message like this:
199 Traceback (most recent call last):
200 File "<string>", line 63, in <module>
201 File "/home/gui/.vim/black/lib/python3.7/site-packages/black.py", line 45, in <module>
202 from typed_ast import ast3, ast27
203 File "/home/gui/.vim/black/lib/python3.7/site-packages/typed_ast/ast3.py", line 40, in <module>
204 from typed_ast import _ast3
205 ImportError: /home/gui/.vim/black/lib/python3.7/site-packages/typed_ast/_ast3.cpython-37m-x86_64-linux-gnu.so: undefined symbool: PyExc_KeyboardInterrupt
208 Then you need to install `typed_ast` directly from the source code. The error happens
209 because `pip` will download [Python wheels](https://pythonwheels.com/) if they are
210 available. Python wheels are a new standard of distributing Python packages and packages
211 that have Cython and extensions written in C are already compiled, so the installation
212 is much more faster. The problem here is that somehow the Python environment inside Vim
213 does not match with those already compiled C extensions and these kind of errors are the
214 result. Luckily there is an easy fix: installing the packages from the source code.
216 The package that causes problems is:
218 - [typed-ast](https://pypi.org/project/typed-ast/)
220 Now remove those two packages:
223 $ pip uninstall typed-ast -y
226 And now you can install them with:
229 $ pip install --no-binary :all: typed-ast
232 The C extensions will be compiled and now Vim's Python environment will match. Note that
233 you need to have the GCC compiler and the Python development files installed (on
234 Ubuntu/Debian do `sudo apt-get install build-essential python3-dev`).
236 If you later want to update _Black_, you should do it like this:
239 $ pip install -U black --no-binary typed-ast
244 1. Install [`ale`](https://github.com/dense-analysis/ale)
248 1. Add this to your vimrc:
251 let g:ale_fixers = {}
252 let g:ale_fixers.python = ['black']
257 gedit is the default text editor of the GNOME, Unix like Operating Systems. Open gedit
264 1. `Go to edit > preferences > plugins`
265 1. Search for `external tools` and activate it.
266 1. In `Tools menu -> Manage external tools`
267 1. Add a new tool using `+` button.
268 1. Copy the below content to the code window.
272 Name=$GEDIT_CURRENT_DOCUMENT_NAME
276 - Set a keyboard shortcut if you like, Ex. `ctrl-B`
279 - Output: `Display in bottom pane` if you like.
280 - Change the name of the tool if you like.
282 Use your keyboard shortcut or `Tools -> External Tools` to use your new tool. When you
283 close and reopen your File, _Black_ will be done with its job.
285 ## Visual Studio Code
288 [Python extension](https://marketplace.visualstudio.com/items?itemName=ms-python.python)
289 ([instructions](https://code.visualstudio.com/docs/python/editing#_formatting)).
291 - Alternatively the pre-release
292 [Black Formatter](https://marketplace.visualstudio.com/items?itemName=ms-python.black-formatter)
293 extension can be used which runs a [Language Server Protocol](https://langserver.org/)
294 server for Black. Formatting is much more responsive using this extension, **but the
295 minimum supported version of Black is 22.3.0**.
299 Use [sublack plugin](https://github.com/jgirardet/sublack).
303 If your editor supports the [Language Server Protocol](https://langserver.org/) (Atom,
304 Sublime Text, Visual Studio Code and many more), you can use the
305 [Python LSP Server](https://github.com/python-lsp/python-lsp-server) with the
306 [python-lsp-black](https://github.com/python-lsp/python-lsp-black) plugin.
310 Use [python-black](https://atom.io/packages/python-black) or
311 [formatters-python](https://atom.io/packages/formatters-python).
313 ## Gradle (the build tool)
315 Use the [Spotless](https://github.com/diffplug/spotless/tree/main/plugin-gradle) plugin.
319 Add the following hook to your kakrc, then run _Black_ with `:format`.
322 hook global WinSetOption filetype=python %{
323 set-option window formatcmd 'black -q -'
329 Use [Thonny-black-code-format](https://github.com/Franccisco/thonny-black-code-format).
