If not, *Black* will look at the contents of the first outer matching

You'll find *Black*'s own .flake8 config file is configured like this.
Having one kind of quotes everywhere reduces reader distraction.
It will also enable a future version of *Black* to merge consecutive
string literals that ended up on the same line (see
-[#26](https://github.com/python/black/issues/26) for details).
+[#26](https://github.com/psf/black/issues/26) for details).
Why settle on double quotes? They anticipate apostrophes in English
text. They match the docstring standard described in [PEP 257](https://www.python.org/dev/peps/pep-0257/#what-is-a-docstring).
To install with [vim-plug](https://github.com/junegunn/vim-plug):
```
-Plug 'python/black'
+Plug 'psf/black'
```
or with [Vundle](https://github.com/VundleVim/Vundle.vim):
```
-Plugin 'python/black'
+Plugin 'psf/black'

Let me know if this requires any changes to work with Vim 8's builtin
`packadd`, or Pathogen, and so on.

+There is no official blackd client tool (yet!). You can test that blackd is
+working using `curl`:
+
+```
+blackd --bind-port 9090 & # or let blackd choose a port
+curl -s -XPOST "localhost:9090" -d "print('valid')"
+```
+
### Protocol
`blackd` only accepts `POST` requests at the `/` path. The body of the request
`.pre-commit-config.yaml` in your repository:
```yaml
repos:
-- repo: https://github.com/python/black
+- repo: https://github.com/psf/black
rev: stable
hooks:
- id: black
Avoid using `args` in the hook. Instead, store necessary configuration
in `pyproject.toml` so that editors and command-line usage of Black all
-behave consistently for your project. See *Black*'s own `pyproject.toml`
+behave consistently for your project. See *Black*'s own [pyproject.toml](/pyproject.toml)
for an example.
If you're already using Python 3.7, switch the `language_version`
`file-mode` is an int flag that determines whether the file was formatted as 3.6+ only,
as .pyi, and whether string normalization was omitted.
+To override the location of these files on macOS or Linux, set the environment variable
+`XDG_CACHE_HOME` to your preferred location. For example, if you want to put the cache in
+the directory you're running *Black* from, set `XDG_CACHE_HOME=.cache`. *Black* will then
+write the above files to `.cache/black/<version>/`.
## Used by
The following notable open-source projects trust *Black* with enforcing
a consistent code style: pytest, tox, Pyramid, Django Channels, Hypothesis,
-attrs, SQLAlchemy, Poetry, PyPA applications (Warehouse, Pipenv, virtualenv).
