A small C wrapper program (reattach-to-user-namespace) plus documentation that fixes broken Mac OS X pasteboard (pbcopy/pbpaste) access inside tmux and unpatched screen sessions. The functionality was merged into tmux 2.6, so the tool is mainly needed for older tmux versions.
Use cases
- fix pbcopy and pbpaste not working inside tmux on macOS
- enable clipboard access in screen sessions on Mac OS X
- reattach processes to the user's login namespace under tmux
- configure tmux default-command to preserve macOS clipboard
- make other macOS GUI-connected programs work inside terminal multiplexers
When to choose
- you run an older tmux (< 2.6) or unpatched screen on macOS and need working clipboard access
- you need a lightweight wrapper instead of patching tmux or screen
- other programs lose access to the GUI session when launched from tmux
When to avoid
- you use tmux 2.6 or newer, which has this functionality built in
- you are not on macOS
- you need an actively developed tool with ongoing updates
