Manual page breaks

Primary LanguageLuaMIT LicenseMIT

pagebreak

This filter converts paragraps containing only the LaTeX \newpage or \pagebreak command into appropriate pagebreak markup for other formats. The command must be the only contents of a raw TeX block in order to be recognized. I.e., for Markdown the following is sufficient:

Paragraph before page break

\newpage

Paragraph after page break

Fully supported output formats are:

  • AsciiDoc / Asciidoctor,
  • ConTeXt,
  • Docx,
  • EPUB,
  • groff ms,
  • HTML, and
  • LaTeX.

ODT is supported, but requires additional settings in the reference document (see below).

In all other formats, the page break is represented using the form feed character.

Usage

The filter modifies the internal document representation; it can be used with many publishing systems that are based on pandoc.

Plain pandoc

Pass the filter to pandoc via the --lua-filter (or -L) command line option.

pandoc --lua-filter abstract-section.lua ...

Quarto / R Markdown

The use of this filter with either Quarto or R Markdown is discouraged, as both systems ship with their own fork of this extension. Use those instead.

Note also that Quarto allows to use the {{ pagebreak }} short-code to insert page breaks.

Configuration

The filter can be configured through the pagebreak metadata field.

Example config in YAML frontmatter:

---
pagebreak:
  break-on:
    # Treat paragraphs that contain just a form feed
    # character as pagebreak markers.
    form-feed: true

  # Use a div with this class instead of hard-coded CSS
  html-class: 'page-break'

  # ODT style used for pagebreak paragraphs
  odt-style: 'Pagebreak'
---

Currently supported options:

  • break-on.form-feed: boolean value indicating whether the filter should replace paragraphs that contains nothing but form feed characters with page breaks. Enabling option can have a significant performance impact for large documents and is therefore disabled by default.

  • html-class: If you want to use an HTML class rather than an inline style set the value of the metadata key html-class or the environment variable PANDOC_PAGEBREAK_HTML_CLASS (the metadata 'wins' if both are defined) to the name of the class and use CSS like this:

    @media all {
      .page-break	{ display: none; }
    }
    @media print {
      .page-break	{ display: block; page-break-after: always; }
    }

    Note that this will also be used for EPUB output.

  • odt-style: To use with ODT you must create a reference ODT with a named paragraph style called Pagebreak (or whatever you set the metadata field odt-style or the environment variable PANDOC_PAGEBREAK_ODT_STYLE to) and define it as having no extra space before or after but set it to have a pagebreak after it https://help.libreoffice.org/Writer/Text_Flow.

    (There will be an empty placeholder paragraph, which means some extra vertical space, and you probably want that space to go at the bottom of the page before the break rather than at the top of the page after the break!)

Alternative syntax

The form feed character as the only element in a paragraph is supported as an alternative to the LaTeX syntax described above. See Configuration for info on how to enable this feature.
