Terminal differences that aren't really handled in terminfo include:
- Precise mechanisms of setaf/setbf and interactions with palette-indexed color
- Whether ANSI 39 "Default foreground color" / ANSI 49 "Default background color" can be used distinctly (you just get op, often defined as op=\E[39;49m
- Strikethrough (sgr 9)
- Kitty's weird replacement of RGB matching the default background color
- Ordering of x/y coordinates when retrieving cursor location (this might be u6?)
Desired additions
- A string which can match the terminal's reply to XTVERSION, to test whether we've got a terminfo database which doesn't correspond to the terminal we're actually using.
- Application Synchronized Updates (currently discovered via $2026 query) header and footer
- RGB default background discovery query
- Individual enable/disable for each style. In particular, the ANSI CSI 22 m escape that disables bold/dim ought have a terminfo entry.
- XTPOPCOLORS/XTPUSHCOLORS
Community extensions
These capabilities are not described in the most recent terminfo man page at the time of this writing, but are more or less widespread.
- smxx/rmxx begin and end strikeout mode (terminfo has os, a boolean capability indicating that the terminal supports strikeout)
- Smulx/rmulx begin and end extended underline mode (supports multiple underline forms)
- Su scrolls up some number of lines
