Bookmarklet to generate a commit message for an issue in Linear.app

Your commit messages should include the ID of the issue your code belongs to.
Our preferred syntax prefixes the issue title with its ID in brackets, e.g. [FOO-123] Avatars for users.
Here is how to generate that from an issue in Linear.

Add a new link to your browser's bookmarks bar with the following URL.

javascript:(async () => {
  let output;
  if (document.querySelector('[data-view-id="issue-view"]')) {
    const [id, ...words] = document.title.split(' ');
    output = `[${id}] ${words.join(' ')}`;
  } else {
    let text;
    try {
      text = await navigator.clipboard.readText();
    } catch (error) {
      return alert('Error: Access to clipboard required');
    }
    const titles = [...text.matchAll(/\[((?:\\.|[^\]\\])+)\]\([^)]*\)/g)]
      .map(match => match[1].replace(/\\(.)/g, '$1').trim().replace(/^([A-Z]+-\d+):?\s*/, '[$1] '))
      .filter(Boolean);
    if (!titles.length) {
      return alert('Error: No linear issues selected');
    }
    output = titles.join('; ');
  }
  prompt('Commit message:', output);
})();
