Windows PowerShell remote ssh vim copy to clipboard not works

[soonsolidchentuo]

Description of the new feature/enhancement

Login to Ubuntu through SSH in Powershell and edit files using Vim.

However, when I use "+y, I cannot copy the content to the Windows clipboard. Thank you.

Proposed technical implementation details (optional)

I hope it can copy content like putty. Thanks.

Huh. I was pretty sure we added support for OSC 52 in #5823 (a couple years back now).

Can you capture a script trace of trying to copy in vim this way/? That should tell us how exactly they're settings the keyboard.

I also face the same issue using the micro editor over ssh (which supports osc52). I will try to get a trace.

[soonsolidchentuo]

Sorry I can't upload the trace file. So I update to my repository. trace file

The step:

1. I open a power shell command
2. ssh to server-android
3. open a file by vim
4. try using the v + "+y (ok)
5. exit the vim
6. try to use the shift + ins (failed)
7. try to use the right mouse button ( failed)

Which ssh are you using? ssh.exe that ships with Windows? ssh from a WSL distro? Or some other ssh? And which version of ssh?

Did you make sure to configure vim to actually copy to the clipboard using OSC 52 (using something like https://github.com/fcpg/vim-osc52)/?

[soonsolidchentuo]

I tried to add a plugin named vim-osc52
It works by the command :Oscyank

I'm using OpenSSH's ssh.exe

> ssh -V

Also, micro has inbuilt support for OSC52 (just a config flag clipboard: terminal which I have set).

[carlos-zamora]

Hmm... Could you use debug tap and share the output /? Thanks

[plutonium-239]

This is the relevant output I get from debug tap on selecting and copying:

Thanks! It looks like OSC 52 is not making it up to the terminal emulator at all (you'd expect to see ␛]52; somewhere in there!) I would recommend checking on how to configure vim + oscyank or micro to actually send OSC 52.

[plutonium-239]

how to configure vim + oscyank or micro to actually send OSC 52.

This is handled by setting "clipboard": "terminal" in micro's config, and this works on other terminal emulators (but I've only seen it work on a friend's machine - i.e. works on putty but does not on wt)
But your comment makes sense as well, maybe my ssh server + tmux combination is not sending OSC52s as expected.
Although, I've read that there are different forms of prefixes for control sequences, which are set in tmux terminal overrides (such as Ms=\\E]52;c;%p2%s\\7, could that be a problem?

[soonsolidchentuo]

My solution is this:

1. using "+y to copy the content.
2. using :Osyank to copy to windows

[plutonium-239]

I finally found a solution! Copilot helped :)
Since I'm using tmux (v3.0a), that was not passing through the OSC52 escape sequences (as speculated above). The solution was to add a terminal override in my ~/.tmux.conf as follows:

set -as terminal-overrides ",xterm-256color:Tc:Ms=\\E]52;%p1%s;%p2%s\\007"

Note: change xterm-256color to whatever $TERM is outside of tmux, and the Tc just enables truecolor. (I figured it's good to mention here).

Now I can freely copy from micro without having to use the mouse to invoke wt's selection!
