JQL

A JSON Query Language CLI tool

Installation 🚀

sh cargo install jql

Usage 🐨

If you find some of the following examples confusing, please have a look at The JavaScript Object Notation (JSON) Data Interchange Format.

Accessing the root

json "This is a valid JSON text with one value"

sh jql example.json ''

json "This is a valid JSON text with one value"

Please note that the following is also valid:

sh jql example.json '.'

json "This is a valid JSON text with one value"

Accessing a children

json { "some": { "property": "yay!" } }

sh jql example.json '"some"."property"'

json "yay!"

Please note that the following is also valid:

sh jql example.json 'some.property'

json "yay!"

Accessing an index

json { "primes": [7, 11, 13] }

sh jql example.json 'primes.0'

json 7

Please note that the following is also valid:

sh jql example.json 'primes."0"'

json 7

Accessing a range

json { "cats": [{ "first": "Pixie" }, { "second": "Kitkat" }, { "third": "Misty" }] }

sh jql example.json 'cats.1:2'

json [ { "second": "Kitkat" }, { "third": "Misty" } ]

Please note that you can reverse it:

sh jql example.json 'cats.2:1'

json [ { "third": "Misty" }, { "second": "Kitkat" } ]

Bonus, you can do it again to get it back:

sh jql example.json 'cats.2:1.1:0'

json [ { "second": "Kitkat" }, { "third": "Misty" } ]

Please note that you can still access the children:

sh jql example.json 'cats.2:1.0.third'

json "Misty"

Multi-selection

json { "one": [1, 2, 3], "two": 2, "three": 3 }

sh jql example.json 'one.2:0,two,three'

json [ [ 3, 2, 1 ], 2, 3 ]

Special characters

json { ".valid": 1337 }

sh jql example.json '".valid"'

json 1337
