Yesterday, I upgraded to MacOS Sierra and it broke my clipboard functionality in my tmux + neovim setup.
Here is the behavior:
Whenever I use the clipboard in vim within a tmux session, I get the following vim error:
clipboard: error:
My .vimrc
is huge, but here's what I think might be relevant:
set clipboard=unnamed
In my .tmux.conf
(also truncated for brevity):
set -g prefix ` # use tilde key as prefix bind ` send-key ` # insert tilde by pressing twice set -g history-limit 100000 # set buffer size set -s escape-time 0 # fix escape key in vim set -g allow-rename off # keep window names static set -g default-terminal "screen-256color" # set the TERM to 256 colors set -g base-index 1 # start window count at 1 set -g pane-base-index 1 # start pane count at 1 set -g default-shell $SHELL # use zsh as shell
EDIT: This appears to be related to the bug reported here:
https://github.com/tmux/tmux/issues/543
https://github.com/ChrisJohnsen/tmux-MacOSX-pasteboard/issues/53
This seem to be a regression on macOS Sierra. A solution that worked for me has been mentioned by Josh McGinnis https://github.com/tmux/tmux/issues/543:
brew install reattach-to-user-namespace
Ensure the following is set in .tmux.conf:
set -g default-shell $SHELL set -g default-command "reattach-to-user-namespace -l ${SHELL}"
In .vimrc or ~/.config/nvim/init.vim (for Neovim):
set clipboard=unnamed
Now all is well and I can copy/paste between system <-> vim sessions using vim keybindings and/or system ctrl+c / ctrl+p.
