Supplemental code related to IMathAS

pandoc server

This is used by the "Convert to Word" print version option in IMathAS.

Note:

  • pandoc needs to be installed on the server. Ideally the most recent version. Check the code to update the path if needed.
  • the imgs subdirectory needs to be writable by the web server.
  • the ../datatmp/ directory needs to be writable by the web server.
  • you do not need uniconvertor. That was an experiment that didn't work.

livepoll server

This sets up a websocket server to enable the LivePoll feature in IMathAS.

  • Create a directory and copy into it index.js and package.json
  • Go into the directory and run npm install
  • Create a certs subdirectory

The code is set up to run on SSL, so you'll need to put your SSL keys in the directory indicated in the code. Also change the livepollpassword value.

To setup the SSL

  • Follow the instructions on the Certbot website on how to get a certificate. Note that this will require having a regular (Apache, etc) webserver running as well.
  • Copy livepoll.sh into /etc/letsencrypt/renewal-hooks/deploy/, and edit it so the livepoll_cert_root is the path to the certs directory you created earlier. Make sure to chmod a+x livepoll.sh.
  • You may have to manually copy and chmod the certificates into the directory the first time. The script above should handle updating it when the certs renew.

To keep the server running in the background, you'll need to set up some kind of autostart config.

  • Copy livepoll.service to /lib/systemd/system/, editing the ExecStart path as needed.
  • Start the server using sudo systemctl start livepoll

Once set up, put $CFG['GEN']['livepollserver'] = 'your.server.com' and $CFG['GEN']['livepollpassword'] = 'yourpassword' in your IMathAS config.php.

Note that the livepoll server runs on port 3000, so make sure your server is set to allow connections on port 3000.
