m2h is a simple command-line tool that converts Markdown to HTML with syntax highlighting for code blocks. It allows you to customize the styling by applying different themes at render time.

cargo install m2h --locked

By default, m2h reads Markdown from standard input and outputs HTML.

$ echo "# Hello, world!" | m2h

<h1>Hello, world!</h1>

Code blocks in the Markdown input are annotated with CSS classes rather than inline styles. This allows themes to be applied dynamically at render time.

$ echo $'```rust
fn main() {
    println!("Hello, world!");
}```' | m2h

<pre><code class="language-rust"><span class="source rust"><span class="meta
function rust"><span class="meta function rust"><span class="storage type
function rust">fn ...

You can then apply a theme by supplying CSS that styles these class names.

To list all available themes, run:

m2h theme

To retrieve the CSS for a specific theme, run:

m2h theme <THEME_NAME>

For example:

m2h theme Monokai

This will output the corresponding CSS, which you can include in your HTML.

1. Convert Markdown to HTML:

   cat example.md | m2h > output.html

2. Retrieve the CSS for a theme:

   m2h theme Solarized-Dark > theme.css

3. Include theme.css in your webpage to style the syntax highlighting dynamically.
