Function render_markdown 

pub fn render_markdown(ast: &Document, config: Config) -> String

Render a Markdown AST back to formatted Markdown text

This function takes a parsed Markdown document (AST) and renders it back to clean, well-formatted Markdown text. The output follows consistent formatting rules and can be customized via configuration options.

Arguments

• ast - The Markdown document AST to render
• config - Configuration options controlling the output format

Returns

A String containing the formatted Markdown text

Examples

Basic rendering:

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

let doc = Document {
    blocks: vec![
        Block::Paragraph(vec![
            Inline::Text("Hello ".to_string()),
            Inline::Strong(vec![Inline::Text("world".to_string())]),
        ]),
    ],
};

let config = Config::default();
let markdown = render_markdown(&doc, config);
assert!(markdown.contains("**world**"));

With custom width:

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

let doc = Document { blocks: vec![] };
let config = Config::default().with_width(60);
let markdown = render_markdown(&doc, config);

Round-trip Guarantee

For most valid Markdown documents, the following property holds:

parse(render(parse(input))) ≈ parse(input)

Where ≈ means semantically equivalent AST structures.
