Feature request: use `wokrspace/didRenameFiles` for renaming references

[viktomas]

Problem

When you rename file, the LS client (neovim, VS Code) sends a workspace/didRenameFiles event, e.g.

[DEBUG][2025-08-19 10:44:53] .../vim/lsp/rpc.lua:277	"rpc.send"	{ jsonrpc = "2.0", method = "workspace/didRenameFiles", params = { files = { { newUri = "file:///Users/tomas/workspace/private/notes/tmp/ABC.md", oldUri = "file:///Users/tomas/workspace/private/notes/tmp/B.md" } } } }

Specs: https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#textDocument_didRename

If we respect this notification and use it for renaming all references (the same way we already do for textDocument/rename request (spec)) we could make the rename work in all clients that support workspace/didRenameFiles.

Solution

handle workspace/didRenameFiles notification the same way we do handle textDocument/rename request
