// Remixed from original source: https://gist.github.com/MoOx/93c2853fee760f42d97f
//
// 1. Go to a GitHub Labels page. (e.g., https://github.com/cssnext/cssnext/labels)
// 2. Open your Dev Tools' Console and paste this script.
// 3. Now you have a dump of your labels.
//
// P.S. The JSON output can be later imported using a tool using https://github.com/popomore/github-labels

  const row = el.closest('.Box-row');

  const name = el.textContent.trim();

  const color = (el.getAttribute('style') || '').replace(/\s/g, '').toLowerCase().split(';').filter(item => item.startsWith('background-color'))[0].split(':')[1].substr(1);

  labels.push({ name, description, color });
});
labels = JSON.stringify(labels, null, 2);
console.log(labels);

copy(labels);  // Copy to your clipboard.
