Jex - JSON/YAML interactive explorer

Why?

• In a world that JSON/YAML config files take over the world and JQ is not your taste, use the language you already know to explore the data. Whether it is Python/Hylang or ES6 on your favorite web browser developer tool.

• Fighting the bad practice of using online JSON pretifier/formatter, which is prone to leak credentials contained in JSON/YAML (e.g K8S secret output).

Install

pip install jex

Features

• Supports input JSON/YAML.
• Support exploring via Web browser, python interpreter, hylang interpreter.

Usage

• Just pipe the jex after the command that outputs JSON/YAML.

$ curl -ssL https://api.github.com/users/hvnsweeting/repos | jex

It would open a new window for interactive exploring the data via name data in Python interactive interpreter: This pre-import pprint, all functions in itertools, functools, operator stdlib.
