This extension adds bootstrap alerts support to Python-Markdown.

Install locally using poetry

Usage

There are two different ways to use the extensions. Either, by using its identifier mdx_alerts:

>>> import markdown
>>> md = markdown.Markdown(extensions=["mdx_alerts"])

... or by supplying an instance of AlertExtension:

>>> import markdown
>>> from mdx_alerts import AlertExtension
>>> md = markdown.Markdown(extensions=[AlertExtension()])

Markdown pattern and customization

The pattern starts with two colons follows by the alert level, e.g. info. Everything after the newline character is counted towards the alert message/body until on an empty line the two colons appear again.

:: info
This is the body.

Even multi-line is possible.
::

The above snippet results in:

<div class="alert alert-info" role="alert">
    <h4 class="alert-heading"><strong>Info</strong></h4>
    <p>This is the body.</p>
    <p>Even multi-line is possible.</p>
</div>

Additionally, you can overwrite the default heading by supplying an alternative via the heading= attribute after the alert level:

:: info heading="Alternative Heading"
This is the body.
::

... which results in:

<div class="alert alert-info" role="alert">
    <h4 class="alert-heading"><strong>Alternative Heading</strong></h4>
    <p>This is the body.</p>
</div>
