`shed` canonicalises Python code.
Project description
shed
shed canonicalises Python code. Shed your legacy, stop bikeshedding, and move on. Black++
What does it do?
shed is the maximally opinionated autoformatting tool. It's all about
convention over configuration,
and designed to be a single opinionated tool that fully canonicalises my
code - formatting, imports, updates, and every other fix I can possibly
automate.
There are no configuration options at all, but if the defaults aren't for you that's OK - you can still use the underlying tools directly and get most of the same effect... though you'll have to configure them yourself.
shed must either be run in a git repo to auto-detect the files to format,
or explicitly passed a list of files to format on the command-line.
Features
shed...
- Runs
autoflake, to remove unused imports and variables - Runs
pyupgrade, with autodetected minimum version >= py37 - Runs
isort, with autodetected first-party imports and--ca --profile=blackargs - Runs
black, with autodetected minimum version >= py37 - Formats code blocks in docstrings, markdown, and restructured text docs
(based on
blacken-docs). - If
shed --refactor, also runscom2annand custom refactoring logic usinglibcst.
The version detection logic is provided by black. Because shed supports the same
versions of Python as upstream,
it assumes that the minimum version is Python 3.7.
If you run shed in a Git repository, the name of the root directory is assumed to be a
first-party import. src layout
packages are also automatically detected, i.e. the foo in any paths like
.../src/foo/__init__.py.
Jupyter Notebook support
We recommend using jupytext to save your notebooks in .py or .md files,
in which case shed supports them natively. For a quick-and-dirty workflow,
you can use nbqa shed notebook.ipynb -
nbqa works for any linter or formatter.
Using shed in your editor
We recommend using black in your editor
instead of shed, since it provides our core formatting logic and shed's extra
smarts can be counterproductive while you're actively editing code - for example,
removing an "unused" import just after you add it!
Then, when you're done editing, you can run shed from the command-line, pre-commit
hooks, and your CI system.
Using shed with pre-commit
If you use pre-commit, you can use it with Shed by
adding the following to your .pre-commit-config.yaml:
minimum_pre_commit_version: '2.9.0'
repos:
- repo: https://github.com/Zac-HD/shed
rev: 0.10.4
hooks:
- id: shed
# args: [--refactor, --py39-plus]
types_or: [python, markdown, rst]
This is often considerably faster for large projects, because pre-commit
can avoid running shed on unchanged files.

shed inherits pyupgrade's careful approach to converting string formatting
code. If you want a more aggressive refactoring tool and don't mind checking
for breaking changes, check out flynt.

or django-upgrade.
