What are you using LibCST for?

Reading about all the different use cases helps keep me motivated, and we might learn from each other.

I'll start with an unusual one: @lpetre and I maintain an indexer that uses ScopeProvider to infer cross-references between Python files. This powers automatic dead code removal, and IDE features (like jump-to-def, find-references).

Mainly to improve FastAPI ecosystem.

This week we merged encode/starlette#1376 on Starlette, and I'm creating a codemod to make our users' life easier.

Libcst is used in the micropython-stubber project to merge different partial stub definitions to create stub packages that are published to pypi, and to generate different variations of stub generation scripts that are run on micropython microcontrollers.
