Plain text URLs should auto-hyperlink after pasting into editor

[cknific]

If I hit enter key or spacebar after pasting a plain text URL, I'd expect that it to turn into a hyperlinked URL. Evernote and Word behave like this.

Thanks for raising this. mobiledoc-kit aims to prescribe as little extra-curricular functionality like this as possible, and instead provide a good SDK that allows editor creators to modify it to suit their needs.

In this case, the onTextInput hook could be used to do this auto-formatting. There's an example in the initial PR (here) that describes how this might look:

let urlRegex = /(https?:\/\/[^ ]+) $/; // match a url-like string AND the space after it
editor.onTextInput({
  match: urlRegex,
  run(editor, matches) {
    let url = matches[1];
    let range = editor.range;
    editor.selectRange(range.move(-1).extend(-1 * url.length)); // select the URL
    editor.run(postEditor => {
      let link = postEditor.builder.createMarkup('a', {href: url});
      postEditor.toggleMarkup(link);
    });

    editor.selectRange(range); // restore original cursor position
  }
});

I'd be happy to take a PR that adds this to the README (perhaps in a FAQ or how-to/cookbook section) so that others can see how it could be done. We're not going to bake this functionality into the editor just yet. In the future I could see it being either a default or a plugin that could be added to mobiledoc-kit, though, for those that expect/need this functionality.
