What is AsciiDoc?
AsciiDoc is a text document format used for writing structured documents like user documentation, books, articles, and web pages. It focuses on semantic markup, which means the syntax highlights the meaning and structure of content rather than its appearance. For example, text marked up as a chapter title is clearly differentiated from body text.
AsciiDoc files use a simple, easy-to-read syntax that is similar to Markdown in some ways. However, AsciiDoc provides more extensibility and capabilities out of the box. Key features include:
- Support for document structure like book parts, chapters, sections
- Ability to build modular and reusable content through includes and conditionals
- Powerful formatting capabilities like tables, lists, quotes, sidebars, images, etc.
- Multilingual and internationalization support
- Output to HTML, PDF, ePub, DocBook, man pages, and more
One major advantage of AsciiDoc over raw HTML or Markdown is its flexibility. The same AsciiDoc source can be used to produce HTML for online documentation as well as PDF or ePub for printable manuals. Its clean, semantic markup also makes AsciiDoc easier to write, edit, and translate over time compared to HTML.
Overall, AsciiDoc excels at technical documentation across platforms and outputs. Many open source software projects have adopted it for their documentation needs. The intuitive syntax, extensibility through JavaScript/Python, and powerful out-of-the-box capabilities make AsciiDoc a great choice for technical writing.
