Sharing your dotfiles across operating systems nf should instead have something like:īind-key -T copy-mode 'Enter' send -X copy-pipe-and-cancel "reattach-to-user-namespace pbcopy" If you want to copy from tmux, but don’t want to use vim keys, your. I’m assuming that you’re using tmux with vim, want vi-style bindings for your copying, and have added set-window-option -g mode-keys vi to your. So depending on how recent your version of tmux is, the magic configuration is one of these:īind-key -T copy-mode-vi 'v' send -X begin-selectionīind-key -T copy-mode-vi 'y' send -X copy-pipe-and-cancel "reattach-to-user-namespace pbcopy"īind-key -t vi-copy 'y' copy-pipe "reattach-to-user-namespace pbcopy" Then in April tmux 2.4 introduced breaking changes, changing some names and syntax and making copy-pipe no longer remove you from copy mode by default. Tmux 1.8 (from 2015) added a copy-pipe option that lets you do something with yanked text after tmux copied it to its internal register. To do that, you have to tell tmux to actually send copied text to pbcopy. But by itself, that still won’t get copy and paste working. ![]() That’ll get reattach-to-user-namespace to do its magic whenever tmux starts up, and allow calls to the clipboard to go through. Set-option -g default-command "reattach-to-user-namespace -l bash" nf file.įirst, add this line, replacing bash with your shell of choice. Then, you’ll need to add a few lines to your. Happily, there’s a library called reattach-to-user-namespace that uses some private operating system functions to get tmux access to the pasteboard - but it takes a little configuring, and the correct configuration recently changed. This can get pretty frustrating when you want to copy an error code into Google! So while you can copy text into tmux’s register, tmux can’t put that text on the pasteboard where anything else could get to it. Tmux is run as a daemon process, and daemons haven’t had access to user-level services like the pasteboard since OS X 10.5. It’s pretty nice, but getting copy and paste working within tmux on macOS is surprisingly tricky, due to some peculiarities with MacOS’s security setup. It’s also great for remote pair programming, since you can share a session over the internet. Tmux, if you haven’t used it, is a “terminal multiplexer” that lets you create multiple tabs and panes in a terminal, persist terminal sessions, and (with plugins) send commands from vim to another pane. At Carbon Five it’s pretty common to do our editing in vim embedded in a tmux session. ![]()
