huang.zhiping fe4cdefd6f fix tox python3 overrides
We want to default to running all tox environments under python 3, so
set the basepython value in each environment.

We do not want to specify a minor version number, because we do not
want to have to update the file every time we upgrade python.

We do not want to set the override once in testenv, because that
breaks the more specific versions used in default environments like
py35 and py36.

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")
