New extension for listings of cross-references

[tobydriscoll]

Description

In a book with lots of examples, definitions, etc. scattered across many chapters, it can be handy for the reader to have a single list or table of all such items. I've written an extension to help automate this process.

It's pretty clunky. I'm new to Lua and Pandoc coding, and Pandoc isn't natively set up to work across multiple files. Someone who really knows Quatro could have done it faster and better, I'm sure. But it works, and I know students really appreciated a one-stop summary of examples this past semester.

To get started, use quarto add tobydriscoll/crossref-listings in your project directory. The extension directory has an explanation that is also a demo.

You might want to add your extension to Quarto website, see https://quarto.org/docs/extensions/.

This looks good, thanks for sharing! We have ticket #2138 for precisely this issue in quarto, it's great to see that it's doable as an extension.
