Continue in same line after heading

For some obscure styling reason, I want to start the text after a heading in the same line as the heading. The text should not count towards the heading in the outline for example.

#outline() // to see what is picked up as the heading

= This is my header

This text should start in the same line as the header but be formatted as normal text!

This is what I get actual image

and this is what I want to get

expected image

Solution

  • Headings are placed in a block by default, which prevents inlining. The easiest way to get your behavior is to wrap this block in a box

    #show heading: box

#set heading(numbering: "1.")
#outline()

= Hello, World
#lorem(100)

    enter image description here

    However, keep in mind boxes use rectangular boundaries, so headings that wrap across multiple lines won't continue the paragraph as you expect:

    #show heading: box

#set heading(numbering: "1.")
#outline()

*Beware long headings*

= #lorem(10)
Some following text

    enter image description here

    You can get around this with a more complex show rule, e.g. only showing the numbering + body, but this becomes more difficult to maintain the more heading features you want to support:

    #show heading: it => {
  // Check out all heading information by printing `it.fields`
  // it.fields()
  if it.numbering != none {
    context numbering(it.numbering, ..counter(heading).get())
  }
  h(0.25em)
  it.body
  h(0.25em)
}

#set heading(numbering: "1.")
#outline()

*Long headings are now supported*

= #lorem(10)
Some following text

    enter image description here

    The easiest recommendation is to just use a box and ensure your headings fit on one line (which is usually the case).
