Installation

Prerequisites

Ensure you have Rust installed. If not, install it using Rustup:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Usage

Pretty-print JSON

or from stdin:

cat file.json | jqr

Extract values using JSONPath

jqr file.json '$.user.name'

Example JSON:

Example output:

user:
  name: Alice
  age: 30

Convert YAML to JSON

jqr file.yaml --to-json

Example YAML:
