## NAME

md2man-html - convert md2man(5) flavored [Markdown] text into HTML

## SYNOPSIS

`md2man-html` [*OPTION*]... [*FILE*]

## DESCRIPTION

This program converts the md2man(5) flavored [Markdown] text from the given
*FILE* into HTML and then prints the result to the standard output stream.
If *FILE* is not given, then the standard input stream is read in its place.

### Top-level headings

Each component of the `.TH` directive in roff(7), described under "Top-level
headings" in md2man(5), is wrapped in stylable `<span>` elements as follows:

```html
<span class="md2man-title">...</span>
<span class="md2man-section">...</span>
<span class="md2man-date">...</span>
<span class="md2man-source">...</span>
<span class="md2man-manual">...</span>
```

### Heading permalinks

Self-referencing hyperlinks (for permanent linking) are added to headings by
converting their labels into URI fragments that are unique (using a counter),
lowercase, and squeezed and stripped of HTML tags and non-word characters.

For example, a heading labeled `Ver<s>iON 3(2</s>!4)))` would be emitted as:

```html
<h2 id="ver-ion-3-2-4">Ver<s>iON 3(2</s>!4)))<a name="ver-ion-3-2-4"
href="#ver-ion-3-2-4" class="md2man-permalink" title="permalink"></a></h2>
```

For example, multiple headings labeled `Hello, world!` would be emitted as:

```html
<h2 id="hello-world">Hello, world!<a name="hello-world"
href="#hello-world" class="md2man-permalink" title="permalink"></a></h2>

<h2 id="hello-world-1">Hello, world!<a name="hello-world-1"
href="#hello-world-1" class="md2man-permalink" title="permalink"></a></h2>

<h2 id="hello-world-2">Hello, world!<a name="hello-world-2"
href="#hello-world-2" class="md2man-permalink" title="permalink"></a></h2>
```

### Cross references

Cross references to manual pages are emitted as HTML hyperlinks that have
`class="md2man-reference"` and `href="../man$SECTION/$PAGE.$SECTION.html"`
attributes.

For example, the `printf(3)` cross reference would be emitted as this HTML:

```html
<a class="md2man-reference" href="../man3/printf.3.html">printf(3)</a>
```
