I actually still like LLMs for this. I use rust LSP (rust analyzer) and it supports this, but LLMs will additionally go through and reword all of the documentation, doc links, comments, var names in other funcs in one go, etc.
Are they perfect? Far from it. But it's more comprehensive. Additionally simple refactors like this are insanely fast to review and so it's really easy to spot a bad change or etc. Plus i'm in Rust so it's typed very heavily.
In a lot of scenarios i'd prefer an AST grep over an LSP rename, but hat also doesn't cover the docs/comments/etc.
Shouldn't the LLM have some tool that gives it AST access, LSP access, and the equiv of sed/grep/awk? It doesn't necessarily need to read every file and do the change "by hand".
I linked this elsewhere but, the agent could have a skill to use https://ast-grep.github.io/ to perform such mechanical code changes
That's correct, though you'll still end up needing more than AST/LSP/etc for the same reason AST/LSP/etc isn't enough for me (the human lol), ie comments/docs/etc.
