Latest Release

  • The latest pre-release is version 1.0.0-M5.
  • The latest stable release is version 0.19.5.

If you are starting a new project with Laika, it is recommended to use the latest 1.0 milestone. It is the final milestone and already very close to the first release candidate and will prevent the need for a future migration. 0.19 won't receive any further patches unless a severe issue surfaces.

The library is published to Maven Central for Scala 3, 2.13, 2.12 and supports cats-effect 3.x and Scala.js 1.13+.
The sbt plugin is published for sbt 1.x.

  • No External Tools

    Easy setup without any external tools or languages and only minimal library dependencies.

  • Flexible Runtime

    Laika can be used as an sbt plugin, as a Scala library for the JVM or in the browser via Scala.js.

  • Purely Functional

    Fully referentially transparent, no exceptions or runtime reflection and integration with cats-effect for polymorphic effect handling.

  • Rich Feature Set

    Markdown and reStructuredText as input, HTML, EPUB and PDF as output, integrated preview server and syntax highlighting, link validation, auto-generated navigation, versioned documentation, and much more.

  • Lightweight Theme

    The default Helium theme includes only a minimal amount of handcrafted CSS and JS, no Bootstrap, no frameworks.

  • Highly Extensible

    Process the document AST, adjust rendering for individual AST nodes or extend text markup languages with custom directives.
