Re: Support for OSC 52?

[Neal Fultz]

You could try adding OSC code 52 to ansi.c and friends; eg in the patch I just emailed I added codes 10/12.

Once it's built in to screen's terminal emulator, you no longer need to use the \eP escapes to send the message directly to the outer terminal, screen will propagate it correctly even when nested.

Thanks! The osc52 helper indeed works fine for Alacritty -> SSH ->
screen 4.09.00.

I regularly use nested screens (local+remote), and then the helper
doesn't work anymore. I got it working again like this:

# sed -E -e 's:^:\x1bP:' -e 's:$:\x1b\\:' | \
sed -E -e 's:^:\x1bP\x1bP:' -e 's:$:\x1b\x1b\\\x1b\\\\:' | \

Not sure if there's a better way.
