Swift Markdown

Swift Markdown is a Swift package for parsing, building, editing, and analyzing Markdown documents.

The parser is powered by GitHub-flavored Markdown's cmark-gfm implementation, so it follows the spec closely. As the needs of the community change, the effective dialect implemented by this library may change.

The markup tree provided by this package is comprised of immutable/persistent, thread-safe, copy-on-write value types that only copy substructure that has changed. Other examples of the main strategy behind this library can be seen in SwiftSyntax.

Getting Started Using Markup

In your Package.swift Swift Package Manager manifest, add the following dependency to your dependencies argument:

.package(url: "https://github.com/swiftlang/swift-markdown.git", branch: "main"),

Add the dependency to any targets you've declared in your manifest:

.target(
name: "MyTarget",
dependencies: [
.product(name: "Markdown", package: "swift-markdown"),
]
),

To parse a document, use Document(parsing:), supplying a String or URL:

import Markdown

let source = "This is a markup *document*."
let document = Document(parsing: source)
print(document.debugDescription())
// Document
// └─ Paragraph
// ├─ Text "This is a markup "
// ├─ Emphasis
// │ └─ Text "document"
// └─ Text "."

Please see Swift Markdown's documentation site for more detailed information about the library.
