The consequences of redefining elementary functions and list of figures generation

This post is a development of the post Incorrect hanging indentation - #6 by aarnent

If you uncomment the line target: figure.where(kind: image), from the code below, you will get the error message where() can only be called on element functions. As a consequence, I cannot display the list of figures. ChatGPT told me that this was a consequence of redefining #figure, an element function.

#set figure.caption(position: top, separator: [ — ])

#let ORIfigure = figure
#let figure(..args, caption: "", source: none, body) = ORIfigure( 
    ..args, 
    caption: caption, 
    body + context block( 
    width: measure(body).width, 
  )[ 
    #set list(marker: "Source:") 
    #show list.item: set align(left) 
    #show list.item: set par(justify: true) 
    #set par(leading: 10pt * 1.15) 
    #set text(size: 10pt) 
    #if source != none { 
      v(-3pt) 
      list.item(source) 
    } 
  ]
)

#outline( 
  title: [List of figures],
  target: figure.where(kind: image),
)

#figure( 
  rect( 
    width: 5cm,
    height: 3cm,
  ),
  caption: [A test figure],
  source: lorem(15)
) <label>

Read @label.

My question is whether it’s possible to use the usual syntax #figure(body,caption,source) <label> and, at the same time, be able to generate a list of figures. Thanks in advance.

Well, this doesn’t answer your question, but you can always use std.figure.where(…). See Using “shadowed” definitions - Typst Documentation.
