pyrx

Python implementation of the Rx schema and validation system

Forked

Forked from the main rx github repo Nov 25 '13 because the python implementation deserves its own place and testing and stuff.

The copyright line of the license for the rx repository reads:

The contents of the Rx repository are copyright (C) 2008, Ricardo SIGNES.

The license itself is GPL2: https://github.com/rjbs/rx/blob/master/LICENSE

Requirements

• No external dependencies
• Python2.7 (python3 support coming soon)

Installation

$ pip install pyrx

Usage

import pyrx

rx = pyrx.Factory({"register_core_types": True})

schema_src = {
  "type": "//rec",
  "required": {
    "a": "//str",
    "b": "//int",
  },
  "optional": {
    "c": "//bool",
  },
}

schema = rx.make_schema(schema_src)

schema.check({"a": "a string", "b": 2})  # returns True
schema.check({"a": "a string", "b": "another string"})  # returns False

Testing

I didn't bring the tests over from the rx repo. They used TAP or something I'm not familiar with. The tests included here just run through a couple trivial cases to make sure it doesn't straight-up crash.

Road Map

• Porting tests from the original RX repo (but using unittest)
• Port to python3
• Improve error messages on invalid schema tests
• Improve documentation
