I've attempted something similar to your ast-search tool, but it instead iterates through git history, pulls out the relevant text and then provides the diff to the user. It's a tricky problem because it sits somewhere between text, where a function name could get renamed and it's obvious because it is textually similar, and an AST where 'similarity' is a difficult concept. I struggled to make it usable, but of course there's a module to do half of it that I didn't find initially - https://pypi.org/project/pyastsim/ https://pypi.org/project/pyastsim/
