ajq

ajq is a stream processor developed and published by Ricardo Cabral, currently available at version 0.1.5, with two versions having been released to date. The software is positioned as a jq-like tool, meaning it belongs to the category of command-line stream processors and JSON data processing utilities, and it is designed to handle structured data streams in a manner familiar to users of the widely known jq tool. Its central purpose is to combine the deterministic execution model of ordinary jq with additional, explicitly defined capabilities for semantic matching and extraction. In practice, this means that standard jq operations behave in a predictable, deterministic fashion, while the software extends that baseline with dedicated operations that allow users to perform semantic matching against data and to extract information based on semantic criteria rather than purely structural or syntactic rules. This dual approach makes ajq relevant for use cases in which conventional JSON querying and transformation are not sufficient on their own, such as scenarios where data must be filtered, matched, or extracted according to meaning-oriented conditions while still preserving the reliability and reproducibility expected from deterministic stream processing. Typical use cases therefore include processing JSON or similarly structured streams in pipelines, performing extraction tasks that go beyond simple path-based selection, and integrating semantic operations into workflows that already rely on jq-style tooling. Because ajq keeps ordinary jq execution deterministic, existing habits and expectations from jq usage can carry over, while the added semantic operations are invoked explicitly, keeping the boundary between standard processing and semantic extension clear. As a published software package with version 0.1.5 as its most recent release across its two recorded versions, ajq represents an early-stage project in the stream processing and data extraction category, maintained by a single publisher and aimed at users who need both conventional jq behavior and semantically aware matching and extraction within a single tool.
