Using pymdownx.blocks.details with pymdownx.details

The new pymdownx.blocks.details extension is meant to replace pymdownx.details, 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 pymdownx.details to pymdownx.blocks.details, ensure you disable pymdownx.details 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

Details blocks are an alternative to using pymdownx.details and, in fact, aim to potentially replace them in the future. The output is identical pymdownx.details, 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.details'])

Usage

Admonitions can be specified using the generic block syntax and the name details. A summary can be specified in the header. Additionally, you can apply a specific class like with admonitions if desired.

Details
/// details | Some summary
Some content
///
Some summary

Some content

Like with Admonitions, you can specify a special class to define the type via the type option. If type is set, a class with that name will be added, and if there is no summary, the type will be used as the summary: note -> Note.

Details
/// details | Some summary
    type: warning

Some content
///
Some summary

Some content

If you wish to specify a details as open (or not collapsed), simply use the option open.

Details Open
/// details | Some summary
    open: True

Some content
///
Some summary

Some content

Like admonitions, you can specify and register special shortcuts for certain details types, but unlike admonitions, details does not register any default types by default.

import markdown
from pymdownx.blocks.details import Details

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

And then you can use your defined types:

/// some-custom-type | Some summary
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.details import Details

md = markdown.Markdown(
    extensions=['pymdownx.blocks.details'],
    extension_configs={
        'pymdownx.blocks.details": {
            '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:

/// details | 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.

/// details | 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.
