Templates

A lot of the power from AutoAPI comes from templates. We are basically building a mapping from code to docs, and templates let you highly customise the display of said docs.

Structure

Every type of data structure has its own template. It uses the form language/type.rst to find the template to render. The full search path is:

language/type.rst

So for a .NET Class, this would resolve to:

dotnet/class.rst

We provide base/base.rst as an incredibly basic output of every object:

.. {language}:{type}:: {name}

Custom Filters, Tests, and Globals

The autoapi_prepare_jinja_env configuration option allows you to pass a callback that can edit the jinja2.Environment object before rendering begins. This callback, among other things, can be used to add custom filters, tests, and/or globals to the Jinja environment. For example:

def autoapi_prepare_jinja_env(jinja_env):
        jinja_env.filters["my_custom_filter"] = lambda value: value.upper()

Context

Every template is given a set context that can be accessed in the templates. This contains:

autoapi_options: The value of the autoapi_options configuration option.
include_summaries: The value of the autoapi_include_summaries configuration option.
obj: A Python object derived from PythonMapperBase.
sphinx_version: The contents of sphinx.version_info.

The object in obj has a number of standard attributes that you can reliably access per language.

Warning

These classes should not be constructed manually. They can be reliably accessed through templates only.

jinja_env – A template environment for rendering this object

Required attributes:

Variables:

Sluggified path for filenames

Slugs to a filename using the follow steps

Decode unicode to approximate ascii
Remove existing hyphens
Substitute hyphens for non-word characters
Break up the string as paths

property ref_directive

property ref_name

Return object name suitable for use in references

Escapes several known strings that cause problems, including the following reference syntax:

:dotnet:cls:`Foo.Bar<T>`

As the <T> notation is also special syntax in references, indicating the reference to Foo.Bar should be named T.

See: https://www.sphinx-doc.org/en/master/#role-cpp:any

property ref_short_name: Same as above, return the truncated name instead

property ref_type

resolve_spec_identifier(obj_name)

Find reference name based on spec identifier

Spec identifiers are used in parameter and return type definitions, but should be a user-friendly version instead. Use docfx references lookup mapping for resolution.

If the spec identifier reference has a spec.csharp key, this implies a compound reference that should be linked in a special way. Resolve to a nested reference, with the corrected nodes.

Note

This uses a special format that is interpreted by the domain for parameter type and return type fields.

Parameters:: obj_name – spec identifier to resolve to a correct reference
Returns:: resolved string with one or more references
Return type:: str

property short_name: Shorten name property

property source

property top_namespace

static transform_doc_comments(text)

Parse XML content for references and other syntax.

This avoids an LXML dependency, we only need to parse out a small subset of elements here. Iterate over string to reduce regex pattern complexity and make substitutions easier
