See the History of a Method with git log -L

November 19, 2023

Simon posted an article from Caleb on a way to get the history of a method.

It works with Python out of the box:

git log -L :path_with_format:__init__.py

That command displays a log (with diffs) of just the portion of commits that changed the path_with_format function in the __init__.py file.

Note that it doesn’t appear to work with a method in a class so just get the history of the class

> git log -L :OpenWeather:get_weather/openweather.py
