Since releasing Rich 1.0.0 I've discovered that terminals support hyperlinks. And I don't mean the helpful highlighting of URLs that most terminals do, I mean actual HTML-like hyperlinks that launch a browser.
This was news to me, as I've never seen this feature in the wild. I just had to add it to Rich. The easiest way to output hyperlinks is via console markup. Here's a simple example:
This will output the text "Visit my blog!" in the terminal where the word "blog" is a clickable link that opens the browser.
This is a relatively new (2017) addition to the spec, so it isn't supported on all terminal apps. If your terminal doesn't support hyperlinks then the link won't be clickable, but you will see the text as normal.
