Terminal I/O for Go with no terminfo: double-buffered cell diffing, true colour with automatic 256-colour fallback, raw key and mouse input, and the same API in a browser through xterm.js.
- Cell-level diffing: only changed cells emit escape sequences
- True colour and xterm-256 with perceptual mapping and blend modes
- Raw input: keys, modifiers, UTF-8, SGR mouse, resize
- Unix and WebAssembly backends behind one interface
- An immediate-mode TUI toolkit and inline CLI output as sub-packages
