## What it is
A Vim plugin that runs the currently open Python file through Flake8, a static syntax and style checker, and displays errors in Vim's quickfix window. It supersedes the older vim-pyflakes and vim-pep8 plugins.

## Use cases
- lint python code inside vim
- run flake8 on the current file with a keypress
- show python style errors in the quickfix window
- jump to flake8 error locations in vim
- show flake8 warnings as gutter signs in vim

## When to choose
- you edit Python in Vim and want on-demand Flake8 checks
- you prefer a lightweight plugin over a full LSP setup
- you want quickfix integration and gutter signs for lint errors

## When to avoid
- you use Neovim with a modern LSP/diagnostic setup like nvim-lint or ALE
- you need asynchronous linting while typing
- you don't have the flake8 binary installed

## Facets
- artifact type: plugin
- maturity: maintenance
- function: linter, developer-tools
- domain: developer-tools, text-editors
- platform: editor-plugin, cli
- tags: vim, flake8, python-linting, quickfix, static-analysis, python
