AutoDocProcessor

AutoDocProcessor(md: Markdown, *, handlers: Handlers, autorefs: AutorefsPlugin)

Bases: BlockProcessor

Our "autodoc" Markdown block processor.

It has a test method that tells if a block matches a criterion, and a run method that processes it.

It also has utility methods allowing to get handlers and their configuration easily, useful when processing a matched block.

Parameters:

  • md

    (Markdown) –

    A markdown.Markdown instance.

  • handlers

    (Handlers) –

    The handlers container.

  • autorefs

    (AutorefsPlugin) –

    The autorefs plugin instance.

Methods:

  • run

    Run code on the matched blocks.

  • test

    Match our autodoc instructions.

Attributes:

  • md

    The Markdown instance.

  • regex

    The regular expression to match our autodoc instructions.

BaseHandler

BaseHandler(*args: Any, **kwargs: Any)

The base handler class.

Inherit from this class to implement a handler.

You will have to implement the collect and render methods. You can also implement the teardown method, and override the update_env method, to add more filters to the Jinja environment, making them available in your Jinja templates.

To define a fallback theme, add a fallback_theme class-variable. To add custom CSS, add an extra_css variable or create an 'style.css' file beside the templates.

If the given theme is not supported (it does not exist), it will look for a fallback_theme attribute in self to use as a fallback theme.

Other Parameters:

  • theme (str) –

    The theme to use.

  • custom_templates (str | None) –

    The path to custom templates.

  • mdx (list[str | Extension]) –

    A list of Markdown extensions to use.

  • mdx_config (Mapping[str, Mapping[str, Any]]) –

    Configuration for the Markdown extensions.

Methods:

  • collect

    Collect data given an identifier and user configuration.

  • do_convert_markdown

    Render Markdown text; for use inside templates.

  • do_heading

    Render an HTML heading and register it for the table of contents. For use inside templates.

  • get_aliases

    Return the possible aliases for a given identifier.

  • get_extended_templates_dirs

    Load template extensions for the given handler, return their templates directories.

  • get_headings

    Return and clear the headings gathered so far.

  • get_inventory_urls

    Return the URLs (and configuration options) of the inventory files to download.

  • get_options

    Get combined options.

  • get_templates_dir

    Return the path to the handler's templates directory.

  • load_inventory

    Yield items and their URLs from an inventory file streamed from in_file.

  • render

    Render a template using provided data and configuration options.

  • render_backlinks

    Render backlinks.

  • teardown

    Teardown the handler.

  • update_env

    Update the Jinja environment.

Attributes:

  • custom_templates

    The path to custom templates.

  • domain (str) –

    The handler's domain, used to register objects in the inventory, for example "py".

  • enable_inventory (bool) –

    Whether the inventory creation is enabled.

  • env

    The Jinja environment.

  • extra_css (str) –

    Extra CSS.

  • fallback_config (dict) –

    Fallback configuration when searching anchors for identifiers.

    Fallback theme to use when a template isn't found in the configured theme.

  • md (Markdown) –

    The Markdown instance.

  • mdx

    The Markdown extensions to use.

  • mdx_config

    The configuration for the Markdown extensions.

  • name (str) –

collect

Collect data given an identifier and user configuration.

In the implementation, you typically call a subprocess that returns JSON, and load that JSON again into a Python dictionary for example, though the implementation is completely free.

Parameters:

  • identifier

    (str) –

    An identifier for which to collect data. For example, in Python, it would be 'mkdocstrings.handlers' to collect documentation about the handlers module. It can be anything that you can feed to the tool of your choice.

  • options

    (HandlerOptions) –

    The final configuration options.

Returns:

  • CollectorItem

    Anything you want, as long as you can feed it to the handler's render method.

    The name of the handler. Really, it's the name of the Python module holding it.

  • handler_config

    (dict | None, default: None ) –

Highlighter

Highlighter(md: Markdown)

Bases: Highlight

Code highlighter that tries to match the Markdown configuration.

Picking up the global config and defaults works only if you use the codehilite or pymdownx.highlight (recommended) Markdown extension.

  • If you use pymdownx.highlight, highlighting settings are picked up from it, and the default CSS class is .highlight. This also means the default of guess_lang: false.

  • Otherwise, if you use the codehilite extension, settings are picked up from it, and the default CSS class is .codehilite. Also consider setting guess_lang: false.

  • If neither are added to markdown_extensions, highlighting is enabled anyway. This is for backwards compatibility. If you really want to disable highlighting even in mkdocstrings, add one of these extensions anyway and set use_pygments: false.

The underlying implementation is pymdownx.highlight regardless.

Parameters:

  • md

    (Markdown) –

    The Markdown instance to read configs from.

on_post_build

on_post_build(config: MkDocsConfig, **kwargs: Any) -> None

Teardown the handlers.

Hook for the on_post_build event. This hook is used to teardown all the handlers that were instantiated and cached during documentation buildup.

For example, a handler could open a subprocess in the background and keep it open to feed it "autodoc" instructions and get back JSON data. If so, it should then close the subprocess at some point: the proper place to do this is in the handler's teardown method, which is indirectly called by this hook.

Parameters:

  • config

    (MkDocsConfig) –

    The MkDocs config object.

  • **kwargs

    (Any, default: {} ) –

    Additional arguments passed by MkDocs.
