A fast, minimal Scala 3 library for parsing CommonMark 0.31.2 Markdown.
Cross‑platform support: JVM, Scala.js, and Scala Native.

• Core CommonMark 0.31.2 compliance: ATX & Setext headings, lists, block quotes, fenced & indented code, HTML blocks, thematic breaks, reference definitions
• Inline parsing: emphasis, strong, code spans, inline & reference links/images, autolinks, raw HTML, entity references
• HTML entity decoding outside of code, with literal preservation inside code spans/blocks
• HTML rendering: safe escaping for <, >, &, and "; outputs standard tags (<p>, <h1–6>, <ul>, <ol>, <pre><code>, <blockquote>, <a>, <img>, etc.)
• Zero runtime dependencies and lightweight API

Try out the Markdown parser in your browser using the Dingus.

Add to your build.sbt:

libraryDependencies += "io.github.edadma" %% "markdown" % "0.0.21"

import io.github.edadma.markdown._

val md = """
# Hello, CommonMark!

This is **bold**, *italic*, and `code`.
"""

val html = renderToHTML(md)

println(html)

The core AST is defined by:

sealed trait Node
case class Document(children: List[Block]) extends Node
sealed trait Block extends Node
case class Paragraph(inlines: List[Inline]) extends Block
case class Heading(level: Int, inlines: List[Inline]) extends Block
case class Code(content: String, info: Option[String]) extends Block
case class BlockQuote(children: List[Block]) extends Block
case class ListBlock(data: ListData, items: List[ListItem]) extends Block
// … Inline types: Text, Emphasis, Strong, CodeSpan, Link, Image, AutoLink, RawHTML, etc.

• Multi-line link reference definitions (v0.0.2)
• Extensions: footnotes, tables, task lists
