AsciiDoc vs Asciidoctor
The Solr Ref Guide is written in AsciiDoc format. This format is generally considered an extension of Markdown, because it has support for tables of contents, better table support, and other features that make it more appropriate for writing technical documentation.
We are using a version of the AsciiDoc syntax along with tools from an open source project called Asciidoctor. This provides full support for the AsciiDoc syntax, but replaces the original Python processor with one written in Ruby. There is a Java implementation, known as AsciidoctorJ. Further extensions from the original AsciiDoc project include support for font-based icons and UI elements.
You can write AsciiDoc without any special tools. It’s simply text, with familiar syntax for bold (
*) and italics (
Having some tools in your editor is helpful, though.
This allows you to see your document in something close to what it might appear like when output to HTML.
