How to Use xm – The Extensible HTML Compiler

Dec 12, 2023 | Programming

In the rapidly evolving world of web development, tools that simplify and enhance the HTML coding experience are invaluable. One such tool is xm, a tiny compiler that brings extensibility to the realm of HTML with a sprinkle of Markdown magic. In this blog post, we’ll walk you through how to install, utilize, and troubleshoot xm for your projects.

What is xm?

xm is a compiler designed for HTML that allows you to import inline HTML files, use slots and fill tags for dynamic content placement, and even incorporate Markdown files seamlessly. Think of it as a magical toolbox that enhances your HTML capabilities!

Installing xm

To get started with xm, you need to install it globally using npm. Here’s how you can do that:

npm i -g xm

Understanding xm’s Usage

Once you have xm installed, you can use it to compile and serve your HTML files easily. Here are the command options available:

  • dev: Compiles HTML files on change and serves the root folder.
  • build: Compiles the HTML files once, creating a build version.
  • help: Displays help for XM commands.

Common options include:

  • –root: Specifies the folder to compile (default is the current directory).
  • –output: Sets the output destination folder, used only with the build command.
  • –htmlOnly: Compile and copy only the built HTML files.

Using the Import Element

The import element allows you to include external HTML files right into your current document. Here’s how to do it:

<html>
    <import src="file.html">
</html>

You can also leverage absolute paths by prefixing with the `–root` value. This helps in organizing your files efficiently.

Importing Markdown Files

xm doesn’t stop at HTML. It has the ability to import Markdown files! This allows for easy formatting of information and can be especially useful for documentation sites. Here’s a quick example:

<import src="README.md">

When importing Markdown files, the front matter is converted into fill elements, enhancing your document’s structure and clarity.

Using Slot and Fill Elements

The slot and fill system allows your HTML files to define “slots” which can later be filled with specific content. Imagine your HTML as a pizza, where each topping (or content) fills its designated slot:

  • The slot is like an empty pizza crust, waiting to be topped.
  • The fill is the flavor that goes into the pizza, giving it life and character.

Here’s how to create a simple structure:

<!-- base.html -->
<html>
    <title><slot name="title"></slot></title>
    <body>
        <slot name="main"></slot>
    </body>
</html>

Troubleshooting

If you encounter issues while using xm, consider these troubleshooting tips:

  • Ensure all your file paths are correct. Double-check the structure of your directories.
  • Make sure you’re running the latest version of xm. You can update it via npm.
  • If an import fails, verify the code within your Markdown or HTML files for syntax errors.
