Pass OSC52 from nested tmux session #565
Description
Disclaimer: I'm not sure if this is relevant to #242 or ever under the scope of this project
A common scenario for nested tmux is the outer one on local machine and the inner one on remote machine over ssh:
Terminal emulator -> Local tmux (outer) -> SSH -> Remote tmux (inner) -> Remote CLI applications
However, OSC52 sequence from remote CLI applications cannot reach the terminal emulator. I tested the following:
| Workflow | Working? |
|---|---|
| Terminal emulator -> Local CLI applications | ✔️ |
| Terminal emulator -> Local tmux -> Local CLI applications | ✔️ |
| Terminal emulator -> SSH -> Remote CLI applications | ✔️ |
| Terminal emulator -> SSH -> Remote tmux -> Remote CLI applications | ✔️ |
| Terminal emulator -> Local tmux -> SSH -> Remote tmux -> Remote CLI applications | ❌ |
Is it possible to make OSC52 sequence from remote CLI applications "passthrough" remote tmux and reach local machine?
