@monopi/bash-live-view

PTY-backed live bash rendering for pi.

Install

pi install npm:@monopi/bash-live-view

Why this exists

The built-in bash tool is great for batch output, but it does not preserve a terminal screen while a command is actively running. This package adds an opt-in PTY mode so commands that depend on terminal behavior can stream into a live widget and still return a normal tool result when they finish.

What it provides

• bash_live_view tool with usePTY?: boolean
• live terminal widget while PTY commands run
• @xterm/headless terminal snapshots rendered back into ANSI lines
• node-pty session management with timeout, abort, and cleanup handling
• /bash-pty <command> slash command
• user_bash support for ! and !! commands
• output truncation, exit summaries, and likely-error highlighting
• spawn-helper permission checks for bundled node-pty binaries

Usage

Agent tool call

await bash_live_view({
	command: "pnpm test --watch",
	timeout: 30,
	usePTY: true,
});

usePTY defaults to false, so bash_live_view can still delegate to pi's original built-in bash behavior when you don't need a PTY.

Slash command

/bash-pty pnpm dev

User bash

!htop
!!pnpm test --watch

Notes

• the live widget only appears for PTY-backed commands
• elapsed time is shown as MM:SS
• PTY output is still truncated to keep tool results compact
• ANSI sanitization strips bell characters and limits CSI parameter payloads

This package ships raw .ts sources for pi to load directly.
