Welcome to our beginner-friendly guide on using the Commonmark-Java library! This powerful Java library simplifies the process of parsing and rendering Markdown text according to the CommonMark specification along with various extensions. Whether you want to convert Markdown into HTML or implement unique features such as strikethrough and tables, you’ve come to the right place!

Getting Started

Before diving into the code, make sure you have the Commonmark-Java library included in your Maven project. To do this, add the following dependencies to your pom.xml file:

<dependency>
    <groupId>org.commonmark</groupId>
    <artifactId>commonmark</artifactId>
    <version>0.23.0</version>
</dependency>

Parsing and Rendering Markdown to HTML

To parse and render Markdown to HTML, follow these straightforward steps:

1. Import the required classes:

import org.commonmark.node.*;
import org.commonmark.parser.Parser;
import org.commonmark.renderer.html.HtmlRenderer;

2. Build the parser and renderer:

Parser parser = Parser.builder().build();
HtmlRenderer renderer = HtmlRenderer.builder().build();

3. Parse your Markdown string:

Node document = parser.parse("This is *Markdown*");

4. Render it to HTML:

String html = renderer.render(document);

And voilà, you’ve just converted Markdown to HTML! It’s as simple as making a sandwich!

Using a Visitor for Processing Nodes

Just like how a gardener inspects and nurtures each plant, you can customize what happens to each node in your Markdown by using a visitor. Here’s how:

class WordCountVisitor extends AbstractVisitor {
    int wordCount = 0; 
    @Override 
    public void visit(Text text) { 
        wordCount += text.getLiteral().split("\\s+").length; 
        visitChildren(text);
    }
}

You just have to create a custom visitor class that extends AbstractVisitor! In this analogy, each word is a flower, and your visitor counts how many flowers bloom in your garden (text).

Customizing HTML Rendering

Sometimes it’s necessary to customize how HTML is rendered. You can achieve this using an AttributeProvider for specific elements:

HtmlRenderer renderer = HtmlRenderer.builder()
        .attributeProviderFactory(new AttributeProviderFactory() {
            public AttributeProvider create(AttributeProviderContext context) {
                return new MyAttributeProvider();
            }
        })
        .build();

In this case, you are giving some plants (HTML elements) a special fertilizer (custom attributes) to help them thrive!

Troubleshooting Common Issues

If you encounter any issues while using Commonmark-Java, consider the following troubleshooting tips:

• Ensure you have the correct version of Java (11 and above).
• Double-check the configuration of your pom.xml file for missing dependencies.
• Look out for syntax errors in your Markdown content which could throw off parsing.
