Lexically sorted outline

[jade blade]

I'm trying to make an outline where the outline heading entries are sorted lexically instead of by their location. (Why? Because of an old joke book I'm rewriting in Typst).
I cannot for the life of me figure out how to modify the list of entries (or even how one would access it) used by the outline, I know how to target specific heading depths, or target specific kinds, but that is the extend of my knowledge.

My first idea was to query all level 1 headings (the ones I care about), sort them and then somehow used them in an outline function, but that fell in the wash.

Ideally a solution might space the entries above each new lexical symbol, buts that's second to it actually working

I think you might need to use a custom solution and not the outline function. The outline allows changing target but not the order

you may be finding the label view which sorts and groups labels in entire workspace.

Okay, I dropped the outline like bluess said, and formatted it muslef instead, which seems to work

context {
  let chapters = query(
    heading.where(
      level: 1,
      outlined: true,
    )
  ).sorted(key: ch => lower(ch.body.text))
  for chapter in chapters {
    let loc = chapter.location()
    let nr = counter(heading).at(loc).first()
    link(
      loc, 
      [ #chapter.body, #nr \ ],
    )
  }
}

Although, now I've run into a fun issue with the text-field of heading bodies not being accessible when headings have special math or other styled content in them. Which is fun, as the outline function seems to handle the cases.
I guess I have to manually provide keys in such cases, or customise (and figure the structures out) even more...

yeah that's another reason why outline doesn't sort I guess, it can't, the heading title is just content 🙂

You could create some sort of elaborate solution where you provide a sort key for every heading
