Usage

• Section defined by "##/###/####..." header (h2/h3/h4...)
• "#" header (h1) will be removed from source content so you can use use your own header
• "##/###/####..." header (h2/h3/h4...) will be removed from source section content so you can use use your own header
• Supports multiple sections from any source

external_markdown requires 2 parameters: url and section name.

{{ external_markdown('url', '## section name') }}

Full Markdown Content

Embed full markdown content from a given url, you can use the following example:

{{ external_markdown('https://raw.githubusercontent.com/fire1ce/DDNS-Cloudflare-Bash/main/README.md', '') }}

Specific Section

Embed markdown section from a given url, you can use the following example:

{{ external_markdown('https://raw.githubusercontent.com/fire1ce/DDNS-Cloudflare-Bash/main/README.md', '## Installation') }}

MkDocs Example

The following example shows how to use the plugin in mkdocs project:

# Example Page

This is an example page.

## Embedding Multiple Markdown Sections From Different URLs

### First Embedded Section

```markdown
{{ external_markdown('https://raw.githubusercontent.com/mkdocs/mkdocs/master/README.md', '## Features') }}
```

### Second Embedded Section

```markdown
{{ external_markdown('https://raw.githubusercontent.com/squidfunk/mkdocs-material/master/README.md', '## Quick start') }}
```

Will produce the following page:

How To Prevent Accidental Interpretation Of Jinja-like Statements

The most frequent issue when adding the MkDocs Embed External Markdown Plugin to an existing mkdocs project, is that some markdown pages may not be rendered correctly, or cause a syntax error, or some other error.

The reason is that if Jinja2 template engine in the MkDocs Embed External Markdown Plugin meets any text that has the standard markers (typically starting with {%} or {{) this will cause a conflict: it will try to interpret that text as a macro and fail to behave properly.

The most likely places where this can occur are the following:

Location in Markdown file (Block or Inline)	Description
Code	Documented Jinja2 statements (or similar syntax), LaTeX
Maths	LaTeX statements
Elsewhere	Some pre-existing templating or macro language, typically with some constructs starting with {# or {{.

Code Blocks Containing Similar Languages

With MkDocs, this situation typically occurs when the website is documenting an application that relies on a djangolike/jinjalike language like:

• Django Template Language
• Jinja2 (Python)
• Nunjucks (Javascript)
• Twig (PHP)
• ...

This may also happen for pages that documents Ansible directives, which often contain variables expressed in a Jinja2 syntax.

Changelog

Version 3.xx

Version 3.0.1 (2023-06-21)

Fixed:

• Crash caused by conflict with Jinja2 render engine expects config parameter from other 3rd party plugins.

Version 3.0.0 (2023-06-20)

Added

• Modularized the code into separate methods for improved readability and maintainability.
• Added type hints for better code understanding and possible performance improvements.
• Included regex pre-compilation for performance enhancement.
• Enhanced URL validation to check for the structure of a URL rather than just the presence of .md.
• Improved error logging through the use of logger.warning instead of print statements, which integrates with MkDocs' logging system.
• Added handling for relative links in the markdown, making them absolute based on the base URL.
• Introduced better error handling for Connection Errors and Status Codes through optional return types.

Removed:

• Removed the use of sys.exit(1) on error, allowing the MkDocs build process to continue even if the plugin encounters an issue.
• Removed the strict requirement for a section level at the beginning of a section name.

Changed

• Switched from using re.compile for one-time regex patterns to using re.match or re.search.
• Extracted the GitHub token once at the beginning of the request method instead of multiple times.
• Replaced the check for .md at the end of the URL with a more comprehensive regular expression to validate the URL's structure.

Fixed:

• Handling of section extraction is now more robust and less prone to errors.

Please note that this is a major version update and may contain breaking changes. Carefully read the updated documentation and test the plugin thoroughly before upgrading in a production environment.
