SuperMemo YouTube React Extension

SuperMemo YouTube extract performance improvements and extensions.

Description

Fixes SuperMemo memleaks and slowdowns with a popup window. Utilize a locally hosted service to remove remote requirements saving up to 500ms per card and utilize the react-player to extend the functionality of incremental video in SM-18. I now consider this a beta and usable, it won't overwrite your cards under expected operation. However, I recommend that you backup your collection before starting to use this extension.

Getting Started

Dependencies

  • python2 or 3
  • SuperMemo 18
  • Windows

Installing

  • Have you checked the files against the yt.htm in your install folder right? Otherwise someone could track what YT vids you're watching.

  • Open the server folder in Terminal

  • Start the server to host resources. Uses port 8000 by default.

python -m SimpleHTTPServer

python3 -m http.server

  • backup YouTube.htm in your install SuperMemo/bin folder

  • if above succeeds, replace YouTube.htm to your installs SuperMemo/bin folder with the one provided in this ZIP

Help

One of my extract timestamps wiped!?

This can rarely happen if you hold ALT+LEFT or ALT+RIGHT and cycle theough many cards quickly. You may recover the times from the title of the card.

The Player is too small, out of place, etc..

Adjust top, left, width and height in sep_embed to adjust screen placement.

Known bugs

  • Closing a player with extracts on it and using the Reopen button will result in errors when making even more extracts.

Differences with vanilla supermemo

  • Extract background colour is lost (blue)
