Admonition

Using pymdownx.blocks.admonition with admonition

The new pymdownx.blocks.admonition extension is meant to replace admonition, they are not meant to be used together. Their output is identical making it easy to transition by simply swapping out the syntax, but using them both together can cause issues as they both generate the same output and confuse each other.

If you are switching from admonition to pymdownx.blocks.admonition, ensure you disable admonition to avoid issues.

9.10 New Experimental Feature

Blocks is currently a new, experimental extension type available in Pymdown Extensions that allows for writing a new kind of block extension in Python Markdown. With this new addition, we've added a number of new extensions utilizing this new extension type. While its intention is to hopefully replace extensions like Details and Tabbed, there are currently no immediate plans to deprecate those plugins.

Any and all feedback regarding these new, experimental blocks is appreciated. Please provide feedback here: #1973.

Overview

Admonition blocks are an alternative to using Python Markdown's built-in extension. The output is identical, but they use the new generic block syntax.

By default, the meta-plugin is registered when pymdownx.blocks is registered, but if you were customizing which meta-plugins get loaded, you can do so by doing the following:

import markdown
md = markdown.Markdown(extensions=['pymdownx.blocks.admonition'])

Usage

Admonitions can be specified using the generic block syntax and the name admonition. A title can be specified in the header.

Admonition
/// admonition | Some title
Some content
///

Some title

Some content

If desired, you can attach a class to an admonition using the the option type. If type is set, a class with that name will be added, and if there is no title, the class name will be used as the title: note -> Note.

Admonition
/// admonition | Some title
    type: warning

Some content
///

Some title

Some content

As a shortcut, Admonitions registers a number of admonition blocks that attach common classes: note, attention, caution, danger, error, tip, hint, warning.

These require you to use their special name. When using these, you do not need to attach class note, attention, etc. as they are already done for you.

Note
/// note | Some title
Some content
///

Some title

Some content

These default types can actually be overridden or extended by using the global types option. Keep in mind that names cannot conflict with other registered Block plugin names you are using.

import markdown
from pymdownx.blocks.admonition import Admonition

md = markdown.Markdown(
    extensions=['pymdownx.blocks.admonition'],
    extension_configs={
        'pymdownx.blocks.admonition": {
            'types': ['note', 'warning', 'some-custom-type']
        }
    }
)

And then you can use your defined types:

/// some-custom-type | Some title
Some content
///

If further control is desired, you can optionally configure a custom block with a name that differs from the actual attached class. You can also configure a default title that is not derived from the attached class.

import markdown
from pymdownx.blocks.admonition import Admonition

md = markdown.Markdown(
    extensions=['pymdownx.blocks.admonition'],
    extension_configs={
        'pymdownx.blocks.admonition": {
            'types': [{'name': some-custom-type', 'class': 'custom', 'title': 'My Default title'}]
        }
    }
)

Now when using:

/// some-custom-type
content
///

It would be the same as using:

/// admonition | My Default Title
    type: custom

content
///

As with all block plugins, you can always add new classes IDs or other attributes via the attributes option.

/// note | Some title
    attrs: {class: class-name: id: id-name}

Some content
///

New 10.5

Specifying custom blocks with specific classes and default titles is new in 10.5.
