This tool is a command-line processor designed for querying, updating, and transforming structured data files. It functions as a versatile engine for manipulating YAML, JSON, TOML, and XML documents, allowing users to perform complex operations directly from the terminal. By utilizing a path-based expression language, it enables precise navigation and modification of data structures within configuration files and infrastructure-as-code workflows.
What distinguishes this tool is its ability to perform in-place document mutations while preserving original formatting, comments, and metadata. It employs a format-agnostic data model that normalizes diverse inputs, facilitating seamless cross-format conversion and interoperability. The engine supports declarative pipeline execution, allowing users to chain multiple operations through standard input and output streams for automated processing in CI/CD environments.
The tool provides a comprehensive suite of capabilities for data manipulation, including arithmetic and logical evaluations, collection sorting, and temporal arithmetic. It handles advanced tasks such as merging multiple files, splitting documents, and dynamically injecting environment variables or external command output into data fields. Users can also enforce security policies by restricting access to external files or system environment variables during execution.
The software is distributed as a standalone binary, supporting shell completion to assist with command-line productivity.
