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 as tool
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)
Usage as library
Call parse_unified_diff with a file like text object or a list of lines of a diff to get a dictionary with filenames as keys and a set of line numbers back.
