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") ... yaql> let(min_orders => $.min_orders) ... -> $.customers.where($.orders.len() >= $min_orders)
