[META] JavaScript bookmarklet to automatically link-ify MEGA IDs (and decryption keys if present)

Converts text like:

/#F!p3x1nTqQ (stuff in between) !g2PCz8gDD0_RL9WhjT1NUw

to click-able links like:

https://mega.nz/#F!p3x1nTqQ!g2PCz8gDD0_RL9WhjT1NUw

Also works with bare Mega IDs only, without decryption keys. Saves you only a couple of seconds, but thought it might be worth sharing.

To install, highlight the entire line below and drag it to your bookmarks bar. (You can edit the bookmark to give it a name.)

To use, click that bookmark when you're on a page that has mega IDs and keys that you want to convert to links.

Note: it will screw up existing mega links on the page because my regex-fu is not strong, so only use it on pages where you want to convert an un-linkified MEGA id.

Source code:

var regex = new RegExp('(#F?![a-zA-Z0-9]{8})(?=(?:.*(![a-zA-Z0-9_-]{22,}))?)', 'g');
document.body.innerHTML = document.body.innerHTML.replace(regex, '$1 (<a href="https://mega.nz/$1$2" target="_blank">https://mega.nz/$1$2</a>)');

  $(this).html(function(_, html) {
    let link, key;
    return html
    .replace(/#F?!\w{8}/, function(a) { link = a; return a; })
    .replace(/![\w-]{22,}/, function(a) { key = a; return a; })
    .replace(/$/, function() {
      let txt;
      if (!link || !key) {
        return '';

      const url = 'https://mega.nz/' + link + key;
      return '<p><b><a href=' + url + ' target=_blank>' + url + '</a></b></p>';
    });
  });
