Hello,
aerc (via the libexec colorize) uses the OSC 8 sequence to mark up
URLs for the terminal emulator. This seems to be currently broken,
I'm investigating with upstream to understand if this is an aerc or
tcell-term bug or something else. However, for the time being I'd
propose to just disable the OSC 8 sequence outputting.
It's broken on (at least)
- xterm
- urxvt
- alacritty
- gnome-terminal
I never noticed before because i use cat(1) as filter for emails.
volker@ noticed it.
thoughts/ok?
