Support textDocument/rename about elixir-ls

[JakeBecker]

My first thoughts on how to approach renaming a function:

• Use Elixir Sense's ElixirSense.Core.Source.subject/3 to find the function at the cursor
• Use Mix.Tasks.Xref.calls/0 to find the file and line numbers that call it
• Somehow find the actual tokens at those lines and replace them

I have no immediate plans to build this myself, so feel free to take a stab at it. You can take a look at some of the existing providers like References and DocumentSymbols to get an idea for how you might implement it. (Steps 1 and 2 are basically the same as the References provider, so I'd say start there.)

In case anyone else plans on or has already started working on this, I have started working on implementing this.

This would be super useful! How can it be done in Elixir? Anything we can help?

This project has moved!

It's now being maintained by proactive volunteers from the Elixir community over at elixir-lsp/elixir-ls. Updates will continue to be published from that repo to the original VS Code extension, so no need to switch plugins if you're using VS Code.

To avoid inundating the new maintainers with issues, please verify that your issue persists with the latest version of the extension (which is published from the new repo) before re-filing your issue there.

Thanks for using ElixirLS!
