Is there a built in method to group sorted citations together?

Instead of this:


I would prefer it to show as: 28-35.

There is no builtin mechanism, and I think one would need to use scheme to do it via \extern. I’ve tried briefly but didn’t got anything, I need to think a bit more about it.

This mechanism is integrated in mogan 1.2.0 version. If you are using beta version of mogan, enable cite-sort style package, then citations is sorted and merged. please give us your feedback.

Looks good, thanks!

But I’m wondering why you make it a package? This process is pretty simple and far from resource intensive, cause it only gets invoked when users update their buffer. It would be weird such a functionality isn’t by default enabled.

Because in digital document, there are hyperlinks on each citation numbers, which should not be collapsed into a range mark.
