说明
jaq is a clone of the JSON processing tool jq, focused on correctness, speed, and simplicity. It is available as both a command-line program (a near drop-in replacement for jq) and as a Rust library. Beyond standard JSON, jaq supports YAML, CBOR, TOML, and XML formats. jaq aims to provide more correct and predictable behavior than jq in edge cases, while maintaining compatibility for common usage. Its core has been security-audited by Radically Open Security.
