Mau Reader: A Plugin for Pelican

Mau Reader is a Pelican plugin that converts the Mau format into HTML.

Requirements

This plugin requires:

• Python 3.6+
• Pelican 4.5+
• Mau 1.3+

Installation

This plugin can be installed via the following command, which will also automatically install Mau itself:

python -m pip install pelican-mau-reader

Usage

The plugin automatically manages all Pelican content files ending with the extension: .mau

Metadata shall be expressed as Mau variables under the pelican namespace. For example:

:pelican.title:Test Mau file with content
:pelican.date:2021-02-17 13:00:00
:pelican.modified:2021-02-17 14:00:00
:pelican.category:test
:pelican.tags:foo, bar, foobar
:pelican.summary:I have a lot to test

The value of a metadata field is a string, just as it is in the standard Markdown format. Please note that Mau variable values include all characters after the colon, spaces included.

All values in the config dictionary are available as variables, so you can specify global values that are valid for all documents.

Custom templates

You can override some or all Mau default HTML templates via the custom_templates configuration variable. For example, should you want to add a permanent link to all headers you can define:

MAU = {
    "custom_templates": {
        "header.html": (
            '<h{{ level }} id="{{ anchor }}">'
            "{{ value }}"
            '<a href="#{{ anchor }}" title="Permanent link">¶</a>'
            "</h{{ level }}>"
        )
    }
}

… and if you want to limit that to only headers of level 1 and 2 you can use:

MAU = {
    "custom_templates": {
        "header.html": (
            '<h{{ level }} id="{{ anchor }}">'
            "{{ value }}"
            '{% if level <= 2 %}<a href="#{{ anchor }}" title="Permanent link">¶</a>{% endif %}'
            "</h{{ level }}>"
        )
    }
}

Table of contents and footnotes

The TOC (Table of Contents) and footnotes are specific to each content file and can be inserted as usual with the Mau commands ::toc: and ::footnotes:.

Custom header anchors

Mau provides a simple function to compute IDs for headers, based on the content. The current function is:

def header_anchor(text, level):
    # Everything lowercase
    sanitised_text = text.lower()

    # Get only letters, numbers, dashes, and spaces
    sanitised_text = "".join(re.findall("[a-z0-9- ]+", sanitised_text))

    # Remove multiple spaces
    sanitised_text = "-".join(sanitised_text.split())

    return sanitised_text

This provides deterministic header IDs that should suit the majority of cases. Should you need something different, you can provide your own function specifying mau.header_anchor_function in the configuration:

MAU = {
    "mau.header_anchor_function": lambda text, level: "XYZ",
}

The example above returns the ID XYZ for all headers (not recommended as it is not unique). The arguments text and level are respectively the text of the header itself and an integer representing the level of depth (e.g., 1 for h1 headers, 2 for h2 headers, and so on).
