PYAXON

======

``pyaxon`` is an `MIT Licensed `_ python library

for `AXON `_. 

AXON is eXtended Object Notation. It's a simple text based format for interchanging

objects, documents and data.

It tries to combine the best of `JSON `_,

`XML `_ and `YAML `_.

Installation

------------

``pyaxon`` runs under Python 2.7, 3.3, 3.4 and 3.5

It can be installed via pip::

	pip install pyaxon

	

It can be installed from sources::

	python setup.py install

Quick start

-----------

First import `axon` module::

	>>> import axon

Load and dump lists, dicts, tuples::

	>>> from decimal import Decimal

	>>> from datetime import datetime, time, date

	>>> text = axon.dumps([['abc абв', 1, 3.14, True],

	[datetime.now(), Decimal('3.14')]])

	>>> print(text)

	["abc абв" 1 3.14 true]

	[^2015-05-12T13:08:37.078189 3.14D]

	

	>>> vals = [{'id':1, 'nickname':'nick', 'time':time(12, 31, 34), 'text':'hello!'},

	{'id':2, 'nickname':'mark', 'time':time(12, 32, 3), 'text':'hi!'}]

	>>> text = axon.dumps(vals)

	>>> print(text)

	{id:1 nickname:"nick" text:"hello!" time:^12:31:34}

	{id:2 nickname:"mark" text:"hi!" time:^12:32:03}	

	>>> text = axon.dumps(vals, pretty=1)

	>>> print(text)

	{ id: 1

	  nickname: "nick"

	  text: "hello!"

	  time: ^12:31:34}

	{ id: 2

	  nickname: "mark"

	  text: "hi!"

	  time: ^12:32:03}

	>>> vals == axon.loads(text)

	True

	  

	>>> vals = [[{'a':1, 'b':2, 'c':3}, {'a':[1,2,3], 'b':(1,2,3), 'c':{1,2,3}}]]

	>>> text = axon.dumps(vals)

	>>> print(text)

	[{a:1 b:2 c:3} {a:[1 2 3] b:(1 2 3) c:{1 2 3}}]

	>>> text = axon.dumps(vals, pretty=1)

	>>> print(text)

	[ { a: 1

	    b: 2

	    c: 3}

	  { a: [1 2 3]

	    b: (1 2 3)

	    c: {1 2 3}}]

	>>> vals == axon.loads(text)

	True

Dump, load objects in "safe" mode::

	

    >>> vals = axon.loads('person{name:"nick" age:32 email:"[email protected]"}')

    >>> print(type(vals[0]))

    

    >>> print(vals[0])

    node('person', {'email': '[email protected]', 'age': 32, 'name': 'nick'})

    >>> text = axon.dumps(vals)

    >>> print(text)

    person{age:32 email:"[email protected]" name:"nick"}

    >>> text = axon.dumps(vals, pretty=1)

    >>> print(text)

    person

      age: 32

      email: "[email protected]"

      name: "nick"

    >>> text = axon.dumps(vals, pretty=1, braces=1)

    >>> print(text)

    person {

      age: 32

      email: "[email protected]"

      name: "nick"}

Dump, load objects in unsafe mode::

	class Person:

	    def __init__(self, name, age, email):

	        self.name = name

	        self.age = age

	        self.email = email

        

	    def __str__(self):

	        return "Person(name=%r, age=%r, email=%r)" % (self.name, self.age, self.email)

	@axon.reduce(Person)

	def reduce_Person(p):

	    return axon.node('person', {'name':p.name, 'age':p.age, 'email': p.email})

	@axon.factory('person')

	def factory_Person(attrs, vals):

	    return Person(name=attrs['name'], age=attrs['age'], email=attrs['email'])

	

	>>> p = Person('nick', 32, '[email protected]')

	>>> text = axon.dumps([p])

	>>> print(text)

	person{age:32 email:"[email protected]" name:"nick"}

	>>> val = axon.loads(text, mode='strict')[0]

	>>> print(val)

	Person(name='nick', age=32, email='[email protected]')

	

Features

--------

1. Provide simple API for loading and dumping of objects in textual AXON format.

2. Provide safe loading and dumping by default.

3. Provide unsafe loading and dumping of objects on the base of registration of factory/reduce callables.

4. Provide a way for fully controlled by application/framework/library unsafe loading and dumping.

5. It's sufficiently fast so as to be useful.
