outliner

outliner

Outliner produces an outline of an HTML document in markdown format, suitable for use as a table of contents.

Installation

If you have Go installed on your system, run:

$ go install -v git.sr.ht/\~javiljoen/outliner@latest

Usage

Run the outliner command, passing in the HTML document via stdin. The repo contains an example document named test.html.

$ outliner < test.html
1. [Section A](#a)
    1. [Section A.1](#a1)
        1. [Section A.1.i](#a1i)
        2. [Section A.1.ii](#a1ii)
    2. [Section A.3](#a2)
2. [Section B](#b)

The input HTML is expected to have the following structure:

• Each section and subsection below the main container element (i.e. after the title, preamble, etc.) is encapsulated in a <section> element.
• Each section/subsection has a section heading within an <h2>, <h3>, or <h4> element, as a direct child of the <section> element. (Sections below the level of subsubsection are not included in the outline.)
• The id attribute must be set on the <section> element (not the heading element). This will serve as the link target in the generated outline.

Note: If the HTML is generated by Pandoc, the expected structure can be obtained by using the --section-divs flag.

$ pandoc --section-divs README.md | outliner
