``yajl-py`` is a Pure Python wrapper (implemented using

ctypes) to the excellent Yajl (Yet Another JSON Library) C

library.

``yajl`` and ``yajl-py``, allow for fast stream parsing of JSON

files, which enables the parsing of large files, that would

not fit in memory.

Dependencies

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

    - python 2.7+, python 3.3+

    - `yajl `_

To run the tests you also require:

    - make (to run ``make test``)

    - nose (debian package == ``python-nose``)

    - mock (``pip install mock``)

Install

-------

From within the current directory run::

    pip install .

To install from pypi::

    pip install yajl-py

Usage

-----

The examples directory contains full featured JSON Parsers built using

``yajl`` and ``yajl-py``. See `examples/README.rst `_ for more info.

Notes around strings, python 3, and yajl-py

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

TLDR; if using python3, yajl-py expects bytes and not strings

Python 3 fixed a whole string of issues with strings. Due to these fixes

somethings taken for granted in python 2 are now explicit in python 3. The

major change that affects yajl-py is related to a decision made within ctypes.

Strings going and coming from the ctypes interface to c-code are now bytes.

Although we can make an explicit decision to decode and encode strings

transparently to latin-1 or utf-8, this is an arbitrary choice. Even

though it can be coded in such a way to make the encoding configurable, the

decision has been made to keep with the decision made by ctypes and hence put

the onus on the developer to decode/encode the input/output as necessary.
