Vibe.TUI.TerminalPainter (vibe v0.2.0)

Copy Markdown View Source

Pure terminal-diff state machine for Vibe's TUI runtime.

Receives fully rendered semantic lines and a cursor position in document coordinates. Returns iodata to write to the terminal plus updated state.

Three render paths:

  • First paint — writes all lines, creating native terminal scrollback.
  • Viewport shift — scrolls via \r\n then repaints the visible area.
  • In-place patch — rewrites only changed lines within the current viewport.
