Terminal Bell

A simple OpenCode plugin to ring the terminal bell once a request is complete.

How to Install?

On Linux, save terminal-bell.ts to ~/.config/opencode/plugin/terminal-bell.ts.

terminal-bell.ts

import type { Plugin } from "@opencode-ai/plugin"

export const TerminalBell: Plugin = async ({ project, client, $, directory, worktree }) => {
  return {
    event: async ({ event }) => {
      if (event.type === "session.idle") {
        console.log("Session went idle")
        await Bun.write(Bun.stdout, "\x07")
      }
    }
  }
}

VS Code

If you are using VSCode & SSH, you need to enable terminalBell in the settings, in a project that will be .vscode/settings.json the settings file can be as simple as:

{
    "accessibility.signals.terminalBell": {
        "sound": "on",
        "announcement": "auto",
    }
}

      if (event.type === "session.idle") {
        await Bun.write(Bun.stdout, "\x07")
        try {
          await $`afplay /System/Library/Sounds/Ping.aiff`;
        } catch (err) {
          console.warn("Failed to play audible bell:", err);
        }
      }

This is nice, gets the terminal bell (I have sound off, but I like to use the indication in tmux). Also Ping.aiff is louder it seems.
