foot

A fast, minimal Wayland-native emulator with thorough escape-sequence documentation in its foot-ctlseqs(7) manual page.

Identity

  • TERM: foot (ships its own terminfo; foot-extra is also provided).
  • TERM_PROGRAM: not set.
  • XTVERSION: DCS > | foot(1.x.y) ST.

Documentation

Notable behavior

  • Implements Sixel; does not implement the Kitty graphics protocol.
  • Implements the Kitty keyboard protocol and DEC private mode 2027.
  • Supports OSC 8, 52, 7, 133, 777, and synchronized output (2026).
  • Implements mode 2048 in-band resize notifications.
  • Documents which OSC/CSI sequences are supported in one place, making it a convenient second opinion when reading the xterm document.

Version notes

1.x.y numbering; the CHANGELOG lists each escape-sequence addition under "Added".
