Pi Tui
@mariozechner/pi-tui — Minimal terminal UI framework with differential rendering, CSI 2026 synchronized output, and Component interfaces. Use when building or debugging terminal interfaces, TUI components, Editor, Markdown, SelectList, or handling input and ANSI widths. Use for "differential rendering", "matchesKey", "Focusable IME", even if pi-coding-agent is not mentioned.

Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Grounding
pi-mono/packages/tui/README.md— core TUI concepts, Overlays, Component interface, Focusable IME, Built-in Components, and Differential Rendering.pi-mono/packages/coding-agent/docs/tui.md— agent-specific TUI component usage (if applicable).pi-mono/packages/tui/src/— read specific component implementations when needing deeper context.
Invariants
- Synchronized Output: Uses CSI 2026 for atomic screen updates. Do not attempt to bypass differential rendering with raw
console.logwhen the TUI is active. - Component Interface: Each line returned by
render(width)MUST NOT exceed thewidthparameter; usetruncateToWidthorwrapTextWithAnsi. - IME Support: Components needing text input (cursors) must implement the
Focusableinterface to position the hardware cursor correctly.
Workflows
- Custom Component: Implement
Componentinterface (render,handleInput,invalidate). Check width constraints explicitly. - Overlays: Use
tui.showOverlay(component, options)for floating UI elements like dialogs, menus, or alerts. - Key Detection: Use
matchesKey(data, Key.xxx)for keyboard input detection instead of manual string matching.
Anti-patterns
- Do not use generic string length for text formatting; always use
visibleWidthandtruncateToWidthto account for ANSI escape codes properly. - Do not clear the screen manually; let the differential rendering strategies handle updates.
