No way to assign labels to figures passed to "wrap-content" and "wrap-top-bottom"

[Eugene Belianski]

If what is passed to fixed parameter in wrap-content function is a figure, it becomes impossible to assign a label to it and reference it in the text. This is because currently Typst provides no way to add labels in code mode typst/typst#2317

One potential solution: add a label parameter to wrap-content function which would then add that label if what is passed to the fixed parameter is a figure (and, I suppose, top-label and bottom-label for wrap-top-bottom function, to be added to figures in top-fixed and bottom-fixed).

Non-working example:

#set text(
  font: "Noto Sans Limbu",
  size: 10pt
)
#set page(
  width: 4.25in,
  height: 5.5in,
  margin: (x: 1.1cm, y: 1.2cm),
)
#set par(
  leading: 0.42em, //space between lines
  justify: true,
)
#set heading(
  numbering: "1.1.", 
  supplement: [§]
)
#outline()

#import "@preview/wrap-it:0.1.0": wrap-content

= Introduction <intro>
Here's a working label/reference: @intro.
#figure(
  rect(fill: red, radius: 0.5em, width: 8em, height: 2em),
  caption: [A figure],
) <redrect>
Here's another working label/reference: @redrect

#let fig = figure(
  rect(fill: teal, radius: 0.5em, width: 8em, height: 6em),
  caption: [A figure],
)

#let body = [But it's impossible to reference the figure to the right. #lorem(80)]

#let wrapc(fig, body, align: right) = {
  let boxed = box(fig, inset: (bottom: 0.3em, top: 0.3em)) //box with inset to add some more space
  wrap-content(boxed, align: align)[#body]
}

#wrapc(fig, body, align: top + right) 

[Nathan Jessurun]

You can use square brackets ([]) to assign a label in this case:

#let fig = [
  #figure(
  rect(fill: teal, radius: 0.5em, width: 8em, height: 6em),
  caption: [A figure],
)<another-label>
]

#let body = [Here's a reference to the next one: @another-label. #lorem(80)]

Thanks a lot! I hadn't thought of that. Might be worthwhile to mention that trick in the readme or manual. :)

Yes, came to the issues for this exact reason! Thank you, ntjess!
