A smarter bookmarklet for Pinboard.in; wraps selected text in <blockquote> tags, keeps variables out of the global scope, supports filling tags from rel="tag" markup in the page, and titles from hAtom entry titles.

pinboard-full.js

  // Change `silent` to true to invoke the promptless, self-closing 
  // version of the bookmarklet.

  // Look for a single hAtom entry on the page, and iff one is found, extract
  // the entry-title in place of the document title:
  if(document.querySelector) {
    if(1 === document.getElementsByClassName('hentry').length) {
      title = document.querySelector(
          '.hentry .entry-title, .hentry h1, .hentry h2, .hentry h3'
        ).innerText;
    }
  }
  
  // Grab the text selection (if any) and <blockquote> it in the description.
  if('' !== (text = String(document.getSelection()))) {
    text = ['<blockquote>', text, '</blockquote>', "\n\n"].join('');
