Rx schema and validation system, with added error messages

Project description

pyrx with error messages
====

Python implementation of the [Rx schema and validation system](http://rx.codesimply.com/)

Fork of [pyrx](https://github.com/uniphil/pyrx) with added error messages. Most of the readme is also taken from there, just with updated usage instuctions.


Forked
------

Forked from the main [rx github repo](https://github.com/rjbs/rx) Nov 25 '13
because the python implementation deserves its own place and testing and stuff.

Requirements
------------

* No external dependencies
* Python2.7


Usage
-----

```python
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}).valid # returns True
schema.check({"a": "a string", "b": "another string"}).valid # returns False
schema.check({"a": "a string", "b": "another string"}).message # returns an error message
