项目历史

The PyCQA/isort repository was created in 2013, and PyPI metadata shows the 1.0.0 source distribution uploaded on 2013-12-10. Creator Timothy Crosley later described isort 5 as the refactoring of a ten-year-old project, placing isort among the early Python formatting tools that predated the Black-era formatter consolidation.

The project moved into the PyCQA ecosystem and grew from simple import ordering into a configurable formatter with profiles, editor integrations, pre-commit use, and documented upgrade guides. Its 5.0.0 upgrade guide calls that release the first major release in five years, while the changelog records Python 2 maintenance ending in the 4.3.x line and later compatibility work for newer Python versions.

采用历史

isort became common in Python projects because import order is easy to automate and painful to review by hand. It is packaged by Homebrew, Debian, Ubuntu, Nix, and PyPI, and the project advertises command-line, library, and editor/plugin use.

Its adoption is tied to the broader Python code-quality stack. Documentation and changelog entries repeatedly mention Black compatibility, built-in profiles, pyproject.toml support, pre-commit usage, and editor integration, making it a companion tool for formatters and linters rather than a standalone style checker.

使用方式

Users run `isort` over files or projects to rewrite import blocks, or use it through pre-commit hooks, editor integrations, and CI checks. Official configuration documentation lists `.isort.cfg`, `pyproject.toml`, `setup.cfg`, `tox.ini`, and `.editorconfig` as project configuration surfaces.

The tool can be used conservatively to check import order or actively to rewrite files, with profiles and options controlling section names, known first-party modules, line length, Black compatibility, and skip rules.

为什么软件包爱好者会关心

isort matters to package nerds because it shows how a small style tool becomes infrastructure: it appears in release tooling, pre-commit configs, editor extensions, CI images, and distribution packages. A version bump can affect thousands of downstream style checks even when runtime code is untouched.

It is also a useful marker for Python packaging eras: setup.cfg-era configuration, pyproject.toml adoption, Python 2 support removal, Black compatibility, and later trusted-publishing/release-infrastructure changes all show up in its history.
