A spiritual greeting from your JavaScript code. Because every function deserves a 'Namaste 🙏'

const readline = require("readline");

function initInput({
  onSubmit,
  onExit,
  onInputChange,
  isBackspaceDisabled,
  onPauseToggle,
}) {
  let input = "";
  let paused = false;

  readline.emitKeypressEvents(process.stdin);

  process.stdin.setRawMode(true);
  process.stdin.resume();
  process.stdin.setEncoding("utf8");

  process.stdin.on("keypress", (char, key) => {
    if (key.ctrl && key.name === "c") {
      onExit();
      return;
    }

    // ⏸️ Pause / Resume
    if (key.name === "space") {
      paused = !paused;
      input = ""; // 🔥 CLEAR BUFFER
      onInputChange("");
      onPauseToggle?.();
      return;
    }

    // 🚫 Ignore input when paused
    if (paused) return;

    if (key.name === "return") {
      onSubmit(input);
      input = "";
      onInputChange(input);
      return;
    }

    if (key.name === "backspace") {
      if (!isBackspaceDisabled()) {
        input = input.slice(0, -1);
        onInputChange(input);
      }
      return;
    }

    if (char && char.length === 1) {
      input += char;
      onInputChange(input);
