ANSI OSC 52 support?

ANSI OSC 52 is a sequence to transport some data from remote console app to client’s clipboard. For example, tmux can use it on remote side, and xterm (terminal app), Windows terminal and a number of others – on client side. It would be very convenient to have such a feature in xterm.js. Here is a simple test which sends a string from remote to local clipboard (taken here): printf "\033]52;c;$(printf "%s" "blabla" | base64)\a"

@YingboMa as with anything where the clipboard is touched we want to make sure there aren’t any security concerns (if you log into a malicious server, it could read your clipboard which may have a password in it?), we would need some API to plug the clipboard detection code in anyway I think so that would probably be solved by a warning on the API. Other than that potential issue, it just needs someone to come and help implement it.

Isn’t it worth to assume that since we are selecting text here in xterm session, we have a focus right now? Focus will be lost in situations like some “mirroring” of terminal output but I don’t think this is 1) majority of cases and 2) we should manipulate with clipboard in these situations…

OSC 52 doesn’t mean text is selected. It means the remote process has emitted this sequence. That could happen from a process that’s running, such as sleep 30; printf "\033]52;c;$(printf "%s" "blabla" | base64)\a". No selection necessary, and the terminal could easily be out of focus by the time the sequence is reached.
