jq is a compiled, dependency-light C command-line tool and embeddable libjq library for transforming JSON and text streams. In production it acts as a Unix pipeline filter: it reads JSON, raw text, or JSON text sequences from stdin/files, parses them, evaluates a user-supplied filter expression, and writes transformed output to stdout. The filter language is a functional DSL compiled to a custom bytecode via a Flex lexer (src/lexer.l), Bison grammar (src/parser.y), block-based compiler (src/compile.c), and stack VM (src/execute.c) with tail-call optimization. JSON values are represented by the refcounted jv API (src/jv.c, src/jv.h), with carefully maintained UTF-8 handling and exact decimal parsing.

This repository is a curated list (awesome list) of resources related to jq, a JSON processor. It is not an application or data research project; it is a documentation repository that aggregates links to jq implementations, tools, libraries, tutorials, and use cases. The content is entirely in the README.md file. There is no executable code, no data pipelines, and no software components to analyze. The list is well-organized and comprehensive, serving as a reference for the jq ecosystem.
