YAML metadata extension for Python-Markdown

This extension adds YAML meta data handling to markdown with all YAML features.

As in the original, metadata is parsed but not used in processing.

Metadata parsed as is by PyYaml and without additional transformations, so this plugin is not compatible with original Meta-Data extension.

Basic Usage

import markdown


text = """---
title: What is Lorem Ipsum?
categories:
  - Lorem Ipsum
  - Stupid content
...

Lorem Ipsum is simply dummy text.
"""

md = markdown.Markdown(extensions=['full_yaml_metadata']})
md.convert(text) == '<p>Lorem Ipsum is simply dummy text.</p>'
md.Meta == {'title': 'What is Lorem Ipsum?', 'categories': ['Lorem Ipsum', 'Stupid content']}

Specify a custom YAML loader

By default the full YAML loader is used for parsing, which is insecure when used with untrusted user data. In such cases, you may want to specify a different loader such as yaml.SafeLoader using the extension_configs keyword argument:

import markdown
import yaml

md = markdown.Markdown(extensions=['full_yaml_metadata']}, extension_configs={
        "full_yaml_metadata": {
            "yaml_loader": yaml.SafeLoader,
        },
    },
)
