Get first item of query

[lettuceDestroyer]

I'm trying to set up a template which requires me to make a page break before the first heading.

What I was hoping to achieve was something like this:

  let headings = context query(heading.where(level: 1))
  show headings.at(0): it => pagebreak(weak: true) + it

but I always get this error message expected string, found integer

You're getting the error because the output of the context block is opaque content and not the array. The array is only available within the context block.

But even if you put the whole show rule into the context, it's simply not possible currently to write a show rule based on a query result like this. You'd get an error like "this selector cannot be used with show".

Maybe you can write the template in a simpler way and just include a pagebreak somewhere at a known position?

Here's an alternative solution I just thought of:

#show heading: it => {
  if query(heading).first().location() == it.location() {
    pagebreak()
  }
  it
}

= Introduction
= World

That works, thank you 😸
