flake8-diff-only 0.1.9

Flake8 plugin to show errors only on changed lines

Project: flake8-diff-only

Description

This project provides a plugin for Flake8 that checks only the modified lines of files for style violations.

⚠️ Please note:

• The current implementation of --diff is fundamentally flawed by design.
• The --diff option was deprecated in Flake8 5.0.0.
• The --diff option was removed entirely in Flake8 6.0.0.

This project replicates that deprecated functionality but as a plugin, and naturally inherits the same limitations. However, it has distinct advantages — particularly in legacy codebases, where running full Flake8 checks may produce excessive noise. That's why I decided to recreate this feature in the form of a plugin.

Usage

To install the plugin, run:

pip install flake8-diff-only

To activate this plugin you need to add --diff-only on flake8 calling.
