There's no reason they have to work one symbol at a time - that's just a missing feature in your language server implementation.

Some language servers support modifying the symbols in contexts like docstrings as well.

I’ve never seen an LSP server that lets you rename “Dog” to “Wolf” where your actual class names are “Dog[A-Za-z]*”?

Do you have an example?

IntelliJ's refactor tool?

IntelliJ doesn't use LSP as far as I know.

It does usually make that kind of DogModel -> WolfModel refactoring.

Neither have I; and no, I don't - I misinterpreted what you said.

But I don't see why LSP servers shouldn't support this, still. I'm not sure if the LSP specification allows for this as of current, though.

I would actually love a regexp search-and-replace assisted by either TreeSitter or LSP.

Something that lets me say that I want to replace “Dog\(.*\)” with “Wolf\1”, but where each substitution is performed only within single “symbols” as identified by TS or LSP.

ast-grep supports regex [1] or pattern based [2] matching and replacement.
