Thanks for sharing! Just before the section you quoted, it says: > Zutty passes the subset of VTTEST screens that we care about FWIW, wezterm passes the subset of vttest screens that I care about too :-p More seriously though, I can't use anything from zutty as it has an incompatible license, and that approach still doesn't resolve the main issue that I have with vttest, which is that it requires a human to interpret the display and reverse engineer what's happening from the code. esctest is a much more reasonable target for conformance testing: https://gitlab.freedesktop.org/terminal-wg/esctest/-/merge_requests/6 https://gitlab.freedesktop.org/terminal-wg/esctest/-/merge_r...
