st (suckless simple terminal)

A minimal X11 emulator with a small, readable code base and a culture of user-applied patches; the unpatched program is the reference.

Identity

• TERM: st-256color.
• TERM_PROGRAM: not set.
• DA1: CSI ? 6 c (VT102 class).
• XTVERSION: not supported.

Documentation

• st.suckless.org
• Source
• Patches

Notable behavior

• Truecolor, 256 colors, DECSCUSR, bracketed paste, mouse modes including SGR, alternate screen, and OSC 52 clipboard writes are supported.
• No scrollback, no OSC 8, no graphics, no Kitty keyboard protocol in the stock build; each exists as a community patch.
• Because patched builds are common, record whether a build is stock.
