Use includex to include anything from any file into your markdown documentation.

pip install mkdocs-macros mkdocs-macros-includex

includex can be configured as a pluglet for mkdocs-macros in the mkdocs.yml configuration file:

plugins:
  - search
  - macros:
      modules: ['includex']

Then you can use it to dynamically include file content in your documentation

### Versioning
The version number is defined in the `pyproject.toml` file:
{{ includex("pyproject.toml", start_match="[tool.hatch.version]", code=True, lines=2, caption=True) }}

which would be rendered as

The version number is defined in the pyproject.toml file:

[tool.hatch.version]
path = "includex.py"

tl;dr

• use snippets if you want to recursively include content
• use includex if you want to include content within macros
• use includex if you want to include sections without special markers

The main use case this solves over snippets is that it includes partial content (i.e. a section or block) from a file as-is (i.e. without the need for special markers).

Snippets partially supports this now since v9.6 added support to include sections by lines.¹ Further, v9.7 added to support to sections by name, given that they are marked as such using a special marker comment.²

What includex does additionally is to match the start and end of blocks and include them without the need for any markers or line numbers. While this makes the documentation more prone to break, e.g., when the line that is being matched is changed in a way that it no longer matches, it supports some additional use-cases and requires less custom syntax.

Snippets is implemented as a preprocessor, while includex is implemented as a mkdocs-macros pluglet. This means that snippets are evaluated earlier than includex and prohibits snippets to work with other macros, like this:

{% for file in get_files("docs/") %}
{{ includex(file) }}
{% endfor %}

However, sections included using includex are not evaluated themselves, so includex cannot be nested (yet). If you need nested includes, use snippets instead.
