Are you on macOS and having trouble copying in vim when using tmux?
You may try to yank and paste, and be greeted with an error:
E353: Nothing in register *
Before we go ahead, let's check our tmux version:
$ tmux -V
If you can upgrade to 2.6 on macOS, you should be OK:
Do a dance on OS X 10.10 and above to return tmux to the user namespace, allowing access to the clipboard.
If you're a macOS user using Homebrew and have Mac OS X 10.10 or greater, you can upgrade your tmux via homebrew: $ brew upgrade tmux .
$ brew install reattach-to-user-namespace
Add this to your ~/.zshrc or ~/.bashrc:
if command -v reattach-to-user-namespace > /dev/null; then alias vim="reattach-to-user-namespace vim" alias nvim="reattach-to-user-namespace nvim" fi
Another more automatic away, in your ~/.tmux.conf:
set-option -g default-command "reattach-to-user-namespace -l zsh"
It's required that you start tmux in a fresh server and a new terminal. save all your work, and then exit tmux with $ tmux kill-server .
