System clipboard paste support over OSC 52 in Tmux

[Jendker]

I recently came across the feature in tmux for copying text to the system clipboard using OSC 52, detailed in the tmux GitHub wiki. This leads me to a question: Is there a corresponding feature in tmux for pasting from the system clipboard?

I'm aware that incorporating such functionality might raise security concerns. However, I noticed that some applications, like Neovim, have begun supporting pasting from the system clipboard through OSC 52. Considering this, I'm interested in knowing if tmux has plans to implement a similar feature, which could be beneficial for consistency and workflow efficiency.

Looking forward to any insights or updates on this topic.

Thanks for your ongoing work on tmux.

You can use refresh-client -l.

I have OSC-52 working in tmux using KiTTY (a PuTTY fork). I can copy from tmux to Windows using this and it works well. The other direction, however, I just shift-right-click in KiTTY (same as in PuTTY) to paste into a tmux window which dumps the local clipboard into the tmux window.

I tried refresh-client -l but it didn't work for me. Doesn't refresh-client depend on out-of-band X11 fowarding and having a client like xclip running on the local desktop?

I don't know of anything that could asynchroneously set tmux's clipboard from the client side over the tty, as in, by some "in-band" escape sequence. Like a reverse OSC-52 sequence to retrieve the clipboard. Is there such an escape sequence without depending on X11?

Yes, it is OSC 52 and it is what refresh-client -l uses. Maybe your terminal doesn't support using it to query.
