==============================================
Sphinx directive for RESTful HTTP API examples
==============================================

sphinxcontrib-httpexample is a Sphinx domain extension for describing RESTful HTTP APIs in detail.
It enhances `sphinxcontrib-httpdomain`_ with a simple call example directive.
The directive provided by this extension generates RESTful HTTP API call examples for different HTTP clients from a single HTTP request example.

The audience for this extension are developers and technical writers documenting their RESTful HTTP APIs.
This extension was originally developed for documenting `plone.restapi`_.

.. _sphinxcontrib-httpdomain: https://sphinxcontrib-httpdomain.readthedocs.io/en/stable/index.html
.. _plone.restapi: https://6.docs.plone.org/plone.restapi/docs/source/index.html


Configuration
=============
The URL scheme, either ``http`` or ``https``, used in the generated examples can be configured with the ``httpexample_scheme`` configuration variable.
It defaults to ``http``.

..  code-block:: python

    # conf.py
    httpexample_scheme = "https"


Syntax
======
There are two syntaxes, one each for inline and external sources.

The following example is of inline sources.

..  code-block:: rst

    ..  http:example:: space separated list of tools
        A required inline source of a raw plain text HTTP request example.
        This is required.


        An optional inline source of a raw plain text HTTP response example.
        If present, it must be separated from the request by two blank lines.
        It must begin with either ``HTTP/VERSION_NUMBER`` or ``HTTP ``.

The following example is of external sources.

..  code-block:: rst

    ..  http:example:: space separated list of tools
        :request: ../relative/path/to/plaintext/request/file
        :response: ../relative/path/to/plaintext/response/file

To display the response outside of the tabbed interface, then don't include it in the ``http:example`` directive, but instead list it separately.

For inline sources, use ``code-block`` with the ``http-response`` lexer.

..  code-block:: rst

    ..  http:example:: space separated list of tools
        A required inline source of a raw plain text HTTP request example.
        This is required.

    ..  code-block:: http
        An optional inline source of a raw plain text HTTP response example.

For external sources, use ``literalinclude`` with either the ``http`` or ``http-response`` lexer.

..  code-block:: rst

    ..  http:example:: space separated list of tools
        :request: ../relative/path/to/plaintext/request/file

    ..  literalinclude:: ../relative/path/to/plaintext/response/file
        :language: http


Example
=======

..  code-block:: rst

    ..  http:example:: curl wget httpie requests plone-client

        POST /Plone/folder HTTP/1.1
        Host: localhost:8080
        Accept: application/json
        Content-Type: application/json
        Authorization: Basic YWRtaW46YWRtaW4=


        HTTP 200 OK
        Content-Type: application/json

        {
            "@type": "Document",
            "title": "My Document"
        }


Rendering
=========

..  http:example:: curl wget httpie requests plone-client

    POST /Plone/folder HTTP/1.1
    Host: localhost:8080
    Accept: application/json
    Content-Type: application/json
    Authorization: Basic YWRtaW46YWRtaW4=


    HTTP 200 OK
    Content-Type: application/json

    {
        "@type": "Document",
        "title": "My Document"
    }
