I briefly looked at running Javascript inside PDF a couple of years ago - I think this is possible under the spec, but no major renderers allow it. Could be wrong.

> I think this is possible under the spec, but no major renderers allow it. Thank goodness, though I suppose you could take the position that you already have a full programming language in your document so how could this be worse? Though the idea of distributing node with all my documents seems a bit hairy.

The PDF specification is hundreds of pages.

  I wonder if running PouchDB would count... since it's an offline / online database. I'm wondering if having a PDF that would have data that could self-update if there's an internet connection. Anyone wanna collaborate on something like this? I wonder if having a PDF like this that showed you how your stocks of choice are doing would be interesting.

    Would would be the advantage of this over a website/PWA? That it's more portable? It's more document-like/printable?

      Self-contained, no need for internet unless you want it to update, is forward-compatible with future PDF readers.

  Oh wow - I wonder if this was added to Chrome's PDF engine after I looked into it. Very cool, but a bit concerning at the same time. I have vivid memories of Flash exploitations and all the malware that came with it. I know we've moved on since then, but I still don't see any reason to allow dynamic content in a page layout format.

  On Firefox calculator opens up, but I can't interact with the elements. The second one is an empty page. I suppose it needs to do some initialization first in order to show the page.

If there is one who would, it’d be Adobe Acrobat / Reader, but I don’t think even it does either.
