Module printer 

Markdown pretty-printer for formatting AST back to Markdown.

Render AST to Markdown using render_markdown. Markdown pretty-printer for formatting AST back to Markdown

This module provides functionality to render a Markdown Abstract Syntax Tree (AST) back to formatted Markdown text. The printer supports configurable formatting options and produces clean, readable Markdown output.

Features

• Full AST support: All CommonMark + GFM elements are supported
• Configurable formatting: Control line width, indentation, and spacing
• Pretty-printing: Intelligent line wrapping and formatting
• Round-trip capability: Parse → Render → Parse produces equivalent AST
• GitHub extensions: Tables, task lists, alerts, footnotes, strikethrough

Basic Usage

use markdown_ppp::ast::*;
use markdown_ppp::printer::{render_markdown, config::Config};

let doc = Document {
    blocks: vec![
        Block::Heading(Heading {
            kind: HeadingKind::Atx(1),
            content: vec![Inline::Text("Hello World".to_string())],
        }),
        Block::Paragraph(vec![
            Inline::Text("This is ".to_string()),
            Inline::Strong(vec![Inline::Text("formatted".to_string())]),
            Inline::Text(" text.".to_string()),
        ]),
    ],
};

let config = Config::default();
let markdown = render_markdown(&doc, config);
println!("{}", markdown);

Configuration

Customize the output format using configuration:

use markdown_ppp::printer::{render_markdown, config::Config};
use markdown_ppp::ast::{Document, Block, Inline};

let config = Config::default().with_width(120);
let doc = Document { blocks: vec![Block::Paragraph(vec![Inline::Text("Hello".to_string())])] };
let markdown = render_markdown(&doc, config);
