match-diff-lines

Match a diff to a list of lines from linters and other tools like flake8 or ruff.

Installation

Best to install into a virtual environment with a Python installer like pip or similar.

Usage

Invoke python -m match_diff_lines diff_file tool_output. The diff_file is a file containing the unified diff output you want to check against. The tool_output contains the output of your linter/tool which contains lines in the form of filename:line_num for example:

match_diff_lines.py:59:39: E271 multiple spaces after keyword

If any lines are contained in the diff, then they are printed and exit code 1 is returned.

With bash or zsh you can use temporary named pipes like this:

% python -m match_diff_lines <(git diff HEAD^) <(ruff check)
