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.
Direktiv is a workflow automation and serverless orchestration platform that enables users to define, execute, and manage workflows and services through a web UI or API. The system features a Go-based backend with React/TypeScript frontend, providing namespace-based multi-tenancy, event-driven triggers via CloudEvents and NATS, a plugin-extensible API gateway, and Kubernetes-native service deployment. Key capabilities include workflow execution (YAML/TypeScript), service management, secret/variable storage, file handling, Git-based namespace mirroring, and comprehensive monitoring with OpenTelemetry integration. The architecture follows a microservices-inspired monolith pattern with clear separation between API handling, data storage, execution engine, and gateway plugin systems.
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.
