About
-----

Swagger.py is a Python library for using
`Swagger `__ defined API's.

Swagger itself is best described on the Swagger home page:

Swagger is a specification and complete framework implementation for
describing, producing, consuming, and visualizing RESTful web
services.

The `Swagger
specification `__ defines
how API's may be described using Swagger.

Swagger.py also supports a WebSocket extension, allowing a WebSocket to
be documented, and auto-generated WebSocket client code.

Usage
-----

Install the latest release from PyPI.

::

$ sudo pip install swaggerpy

Or install from source using the ``setup.py`` script.

::

$ sudo ./setup.py install

API
===

Swagger.py will dynamically build an object model from a Swagger-enabled
RESTful API.

Here is a simple example using the `Asterisk REST
Interface `__

.. code:: Python

#!/usr/bin/env python

import json

from swaggerpy.client import SwaggerClient
from swaggerpy.http_client import SynchronousHttpClient

http_client = SynchronousHttpClient()
http_client.set_basic_auth('localhost', 'hey', 'peekaboo')

ari = SwaggerClient(
"http://localhost:8088/ari/api-docs/resources.json",
http_client=http_client)

ws = ari.events.eventWebsocket(app='hello')

for msg_str in iter(lambda: ws.recv(), None):
msg_json = json.loads(msg_str)
if msg_json['type'] == 'StasisStart':
channelId = msg_json['channel']['id']
ari.channels.answer(channelId=channelId)
ari.channels.play(channelId=channelId,
media='sound:hello-world')
ari.channels.continueInDialplan(channelId=channelId)

swagger-codegen
===============

There are the beginnings of a Mustache-based code generator, but it's
not functional... yet.

.. Inspired by the original [swagger-codegen][] project, templates are
written using [Mustache][] templates ([Pystache][], specifically).
There are several important differences.

* The model that is fed into the mustache templates is almost
identical to Swagger's API resource listing and API declaration
model. The differences are listed [below](#model).
* The templates themselves are completely self contained, with the
logic to enrich the model being specified in `translate.py` in the
same directory as the `*.mustache` files.

Data model
==========

The data model presented by the ``swagger_model`` module is nearly
identical to the original Swagger API resource listing and API
declaration. This means that if you add extra custom metadata to your
docs (such as a ``_author`` or ``_copyright`` field), they will carry
forward into the object model. I recommend prefixing custom fields with
an underscore, to avoid collisions with future versions of Swagger.

There are a few meaningful differences.

- Resource listing
- The ``file`` and ``base_dir`` fields have been added, referencing the
original ``.json`` file.
- The objects in a ``resource_listing``'s ``api`` array contains a
field ``api_declaration``, which is the processed result from the
referenced API doc.
- API declaration
- A ``file`` field has been added, referencing the original ``.json``
file.

Development
-----------

The code is documented using `Sphinx `__, which
allows `IntelliJ IDEA `__
to do a better job at inferring types for autocompletion.

To keep things isolated, I also recommend installing (and using)
`virtualenv `__.

::

$ sudo pip install virtualenv
$ mkdir -p ~/virtualenv
$ virtualenv ~/virtualenv/swagger
$ . ~/virtualenv/swagger/bin/activate

`Setuptools `__ is used for
building. `Nose `__ is used
for unit testing, with the `coverage
`__ plugin installed to
generated code coverage reports. Pass ``--with-coverage`` to generate
the code coverage report. HTML versions of the reports are put in
``cover/index.html``.

::

$ ./setup.py develop # prep for development (install deps, launchers, etc.)
$ ./setup.py nosetests # run unit tests
$ ./setup.py bdist_egg # build distributable
