About:
Halibut is a lightweight, plaintext document preparation system designed for producing documentation in multiple output formats, primarily HTML and PostScript. It serves as a simpler alternative to complex systems like LaTeX or DocBook, focusing on ease of use for software documentation. Its main value proposition is providing high-quality formatted output from minimal, readable source files without a steep learning curve.
Key Features:
  • Single-pass compiler for fast processing
  • Supports multiple output formats (HTML, PostScript, PDF, plain text)
  • Simple, readable markup syntax
  • Built-in support for cross-references and indexes
  • Minimal dependencies
Use Cases:
  • Writing software manual pages and technical documentation
  • Generating project websites from a single source
  • Creating printable PDF guides and reference documents
Alternatives:
  • Pandoc – More versatile with wider format support, but heavier dependency
  • Sphinx – More feature-rich for Python projects, but Python-based and complex
  • LaTeX – More powerful for complex typesetting, but significantly steeper learning curve
