Set rule for a document with part sections included in the heading’s level function hierarchy but the part of the label string corresponding to level: 1 (part) not shown for level > 1. In this case, I set the label "I" for parts:
// Create a chapter counter and initialize it to 1
#let chapter-count = state("chapter-count", 1)
#set heading(numbering: (..nums) => {
if nums.pos().len() == 1 {
// Level 1: Roman numerals for Parts
numbering("I", nums.pos().at(0))
} else if nums.pos().len() == 2 {
// Level 2: Use the chapter state counter and increment it
let current = chapter-count.get()
chapter-count.update(n => n + 1)
str(current)
} else {
// Level 3+: Use the chapter number followed by the position within that chapter
let chapter-num = chapter-count.get() - 1 // -1 because it's already incremented for the next chapter
let sub-nums = nums.pos().slice(2)
str(chapter-num) + "." + sub-nums.map(str).join(".")
}
})
= Part One
== Chapter One
=== Section
== Chapter Two
= Part Two
== Chapter Three
=== Section
=== Section
==== Subsection
==== Subsection
= Part Three
== Chaper Four
But your post doesn’t showcase anything. I also have a hard time understanding the first sentence. At least add a full example that people can compile and see how it looks. Better include the output yourself. Then I can see this as a Showcase post. Also, don’t forget to use an appropriate language identifier for code blocks.
Your last sentence makes your post look like it belongs to Questions category.
You can simplify this by using numbering, counter, and spread operator:
#set heading(numbering: (..nums) => {
let chapter-count = counter("chapter counter")
if nums.pos().len() == 1 {
// Level 1: Roman numerals for Parts.
numbering("I", ..nums)
} else if nums.pos().len() == 2 {
// Level 2: Use the chapter state counter and increment it.
chapter-count.step()
str(chapter-count.get().first() + 1)
// or
// context numbering("1", ..chapter-count.get())
} else {
// Level 3+: Use the chapter number followed by the position within that chapter.
numbering("1.1", ..chapter-count.get(), ..nums.pos().slice(2))
}
})

P.S. By “better include the output” I meant the screenshot of the relevant part of the document (like above). The PDF supposed to be uploaded in case a few shortcuts won’t cut it or a bug-related info is needed. Allow sharing PDF and ZIP files on the forum - #10 by laurmaedje
