How to Use MDEx: A Comprehensive Guide

Sep 27, 2023 | Programming

Welcome to the world of MDEx, an Elixir library that acts like a magician, transforming your Markdown into beautiful HTML with a flick of its virtual wand! In this article, we will break down how to utilize this powerful tool.

What is MDEx?

MDEx is a fast and extensible Markdown parser that complies with the CommonMark and GitHub Flavored Markdown specifications. It provides features such as Wiki Links, Discord Markdown tags, and even emoji support!

Installing MDEx

Getting started with MDEx is quite straightforward. Follow these simple steps:

  • Open your Elixir project.
  • Add MDEx to your list of dependencies in the `mix.exs` file:
  • def deps do
      [
        {:mdex, "~> 0.1"}
      ]
    end
  • Run the following command to fetch the dependency:
  • mix deps.get

Using MDEx

Once MDEx is installed, you can start converting Markdown to HTML easily. Here are some examples:

  • To convert a simple header:
  • MDEx.to_html!(# Hello)
  • To use emojis and other extensions:
  • MDEx.to_html!(# Hello :smile:, extension: [shortcodes: true])
  • Even import MDEx’s syntax with the sigil:
  • import MDEx.Sigil
    
    ~M# Hello from ~M sigil

Understanding the Code: An Analogy

Think of MDEx as a chef in the kitchen who prepares a sumptuous dish (HTML) from various ingredients (Markdown). The chef follows a recipe (the code) where:

  • The `to_html!` function serves as the cooking pot where ingredients are mixed to create a delicious final dish.
  • Each line of code corresponds to a step in the recipe, whether it’s chopping vegetables (parsing a header) or seasoning the meal (adding extensions).
  • The sigil is like a special spice that enhances the flavor, allowing you to create unique dishes with varied tastes.

Parsing and Formatting with MDEx

MDEx not only converts Markdown to HTML but also allows you to parse it into an AST (Abstract Syntax Tree). This feature enables you to inspect and manipulate the document structure. Here’s a quick look at how to parse and format:

document = MDEx.parse_document!(# Hello)
MDEx.to_html!(document)

Troubleshooting Common Issues

While MDEx is robust, you might encounter a few bumps along the road. Here are some troubleshooting tips:

  • If you receive a %MDEx.DecodeError, it often means there’s an issue with the input syntax. Double-check the structure of your Markdown.
  • For any confusing errors, refer to the full documentation available in the Hex Docs.
