Auto Glossary is an Obsidian plugin to generate a glossary or a MOC (or a combination of both) from a selected folder.
You can install this plugin directly within Obsidian or you can copy over main.js, styles.css, manifest.json to your vault VaultFolder/.obsidian/plugins/obsidian-auto-glossary/.
You can create the file you want by right-clicking on a folder in Obsidian.
I stopped working on this project. Feel free to contribute to the code of this plugin, since there are more features to be implemented (and it needs a nice refactoring too). You can also share feedback, issues, and ideas.
