YAQL: Yet Another Query Language

================================

YAQL (Yet Another Query Language) is an embeddable and extensible query

language, that allows performing complex queries against arbitrary objects. It

has a vast and comprehensive standard library of frequently used querying

functions and can be extend even further with user-specified functions. YAQL is

written in python and is distributed via PyPI.

Quickstart

----------

Install the latest version of yaql:

    pip install yaql>=1.0.0

Run yaql REPL:

    yaql

Load a json file:

    yaql> @load my_file.json

Check it loaded to current context, i.e. `$`:

    yaql> $

Run some queries:

    yaql> $.customers

    ...

    yaql> $.customers.orders

    ...

    yaql> $.customers.where($.age > 18)

    ...

    yaql> $.customers.groupBy($.sex)

    ...

    yaql> $.customers.where($.orders.len() >= 1 or name = "John")
