Scripting: `showybox`

[mild laurel]

Hello good people, I've got this showybox here (more can be found in template.typ and ommnibus.typ):

  border-color: white,
  title-color: black,
  body-color: black,
  footer-color: black,
  thickness: (left: 1pt),
  radius: 0pt
  ),
  body-style: (
  color: white
  ),
  footer-style: (
  color: white
  ),
  title-style: (
  color: white,
  weight: "bold",
  ),
  sep: (
  dash: "loosely-dashed"
  ),
    title: [Theorem 2.43 (Dimension of a sum).],
    
  )[If $V_1,V_2$ of a #sbs of a #findem #vsp, then $ dim (V_1 + V_2) = dim V_1 + dim V_2 - dim (V_1 sect V_2). $]```

I don't know how to script this box into one command that also conforms to the section number:

`#thm[#number (in this case 43)][#name (Dimension of a sum)][#content1][#content2]...[#contentn](#footer)`

Could someone help me?

#import "@preview/showybox:2.0.1": showybox
#set heading(numbering: "1.")

= First Section

#let thm(number: 0, name: [], ..contents) = showybox(

    border-color: white,
    title-color: black,
    body-color: black,
    footer-color: black,
    thickness: (left: 1pt),

  ),
  title: [Theorem #(context counter(heading).get().at(0)).#number (#name).], 
  ..contents
)


#thm(number: 43, name: [Dimensions of a sum])[

Thanks a lot for the help!

Since you're using ctheorems as well as showybox, you might be interested in combining them: https://github.com/sahasatvik/typst-theorems/issues/15

oh boy here I go wasting another 2 hours fumbling with ctheorems and showybox AGAIN after my template got BTFO

[mild laurel]

Alright folks, one more touch and we're done. Given this fn:

  frame: (
  border-color: silver,
  title-color: silver.lighten(80%),
  footer-color: silver.lighten(90%),
  thickness: (left: 1pt),
  radius: 0pt
  ),
  title-style: (
  color: silver.darken(50%),
  weight: "bold",
  ),
  sep: (
  dash: "loosely-dashed"
  ),
  title: [Exercise #(context counter(heading).get().at(0)).#number (#name).], 
  ..contents
)

Is there a way to make it referable using ref?

For the example above, when I give it the tag <exam1>, typing @exam1 should display Exercise 1.

Here's a solution using ctheorems: #bot-corner message

[mild laurel]

I modified your code, and here is the result:

  thmenv(
    head,
    base,
    base_level,
    (name, number, body, ..args) => {
      name =  if name != none {[(#name)]} else []
      showybox(
        title: [#head #(context counter(heading).get().at(0)).#number #name],
        frame: (
        border-color: blue,
        title-color: blue.lighten(80%),
        footer-color: blue.lighten(90%),
        thickness: (left: 1pt),
        radius: 0pt
        ),
        title-style: (
        color: blue.darken(50%),
        weight: "bold",
        ),
        sep: (
        dash: "loosely-dashed"
        ),
        ..args.named(),
        body
      )
  }).with(
    supplement: head
  )
}```

Problem is that the number doesn't show up:

#example([First], number: [1.1], footer: lorem(20))[
  #lorem(10)
] <first>

This is a reference to @first.```

[pliant moth]

Ah, this appears to be a bug (the reference doesn't work properly if you set the number manually)

On my list of fixes for v2.0.0

[mild laurel]

Great. I'll be using this for now, though.

[mild laurel]

@pliant moth One more thing:

Could you help me with adding breaks? Your code (which I modified) seems to break that function.

[pliant moth]

Oh I see, the thmenv only treats one (the last?) argument as the body ...

[mild laurel]

Right. But I'd like for the thmenv to take multiple arguments.

[pliant moth]

This is because the first argument is automatically treated as the name, and there is no real way for the format function to tell the difference ... you might actually be better off using your older solution especially since you're overriding the numbering anyways

Here's a hacky way around: #bot-corner message

[mild laurel]

I think I've found the final solution (wink wink), shown here: #bot-corner message
