Define document with two of the same output formats

[MikeLydeamore]

Description

I am working on an extension to develop questions and solutions in a single output (https://github.com/MikeLydeamore/unilur). The idea is to produce to two HTML documents from the single QMD. These two formats share all of the same resources (the CSS and LUA filter), but I can't define two sets of HTML outputs in one extension.

I'd like to avoid having to duplicate the lua filter and have two extensions. Is there a way to share assets between extensions, or define multiple HTML output formats in a single extension?

You could try using a + variant to differentiate the two. For example:

format:
  html:
    theme: flatly
  html+sketch:
    theme: sketchy

Users of your extension should then be able to do something like:

quarto render index.qmd --to extensionname-html

or

quarto render index.qmd --to extensionname-html+sketchy

I think that should work...

Both formats would only be rendered if the user were to target them both, or use --to all or the like.

Great this works a treat. I've implemented here: MikeLydeamore/unilur@9d0ed24 https://github.com/MikeLydeamore/unilur/blob/main/_extensions/unilur/_extension.yml

Thanks for your help.

Nice! It actually reads pretty well to add +solution to the format too!
