Glossary to D8

Drupal 8 port on glossify module is started: https://www.drupal.org/project/glossify. might suit your needs.

Back in August, I was tasked with creating a D8 version of this module for a client. Now that I have permission to contribute it, I see that the work on Glossify has surpassed it. So it's a bit redundant at this point but I was encouraged to share it, anyway. It's a very simple port and doesn't have all the features of the original, just what was needed to meet the client's needs. But it's a start if someone wants it. I'm going to upload it as both a patch against the 7.x branch and also a tar file for people who just want to grab the module without trying to patch the D7 branch.

Hmm, I pulled the current 7.x-1.x version and it has a number of problems. Did you fix issues along the way?

It's been awhile since I worked on it but I think I just made a new module loosely based on the old one. So it's basically a D8 module that does some of what the D7 version did rather than a port. I don't know if it has any value to the community now that Glossify work has taken off but it's suiting the needs of the client and there if anyone wants it.
