So I use Emacs because it is a great tool and I am productive with it. I also code on a development box to avoid x86=>aarch64 compatibility issues with many things on the Mac. Lastly I use NixOS and the Nix package manager on the dev server and Mac respectively.
So I hit a problem. I hadn't noticed it until I was screen sharing and needed to grab some text from the file I was looking at and paste it into chat. I couldn't. The problem with running on a remote box via the terminal is the clipboard exists on the remote server and not locally.
I found a solution using something that has been around forever, X11. The workflow is a bit tedious, but definitely scriptable at some point.
First I needed to update my NixOS server to allow X11 forwarding.
