Swagger/OpenAPI 2.0 Parser

Prance

Swagger/OpenAPI 2.0 Parser for Python

Prances provices parsers for Swagger/OpenAPI 2.0 API specifications in Python. It uses swagger_spec_validator to validate specifications, but additionally resolves JSON references in accordance with the Swagger spec.

Mostly the latter involves handling non-URI references; Swagger is fine with providing relative file paths, whereas JSON references require URIs at this point in time.

Usage

Code

Most likely you have spec file and want to parse it:

from prance import ResolvingParser
parser = ResolvingParser('path/to/my/swagger.yaml')
parser.specification  # contains fully resolved specs as a dict

Prance also includes a non-resolving parser that does not follow JSON references, in case you prefer that.

from prance import BaseParser
parser = BaseParser('path/to/my/swagger.yaml')
parser.specification  # contains specs as a dict still containing JSON references

Largely, that’s it. There is a whole slew of utility code that you may or may not find useful, too. Look at the full documentation for details.

Setup

Use virtualenv to create a virtual environment and change to it or not, as you see fit.

Then install the requirements:

$ pip install -r requirements.txt

Development

Test Execution

Run the whole test suite:

$ python setup.py test

Run a single test scenario:

$ pytest tests/test_resolving_parser.py::test_basics

Run tests on multiple Python versions:

$ tox

Run tests on Python 2.7:

$ tox -e py27

A simple test coverage report is automatically generated.
