core-foundation — package search across npm, PyPI, crates.io, RubyGems, Go, Maven & NuGet

AI4R is a lightweight, educational Ruby library featuring clean implementations of core machine learning and AI algorithms—such as decision trees, neural networks, k-means, genetic algorithms, and even a bit size Transformers architecture covering encoder, decoder, and seq2seq variations. Designed with simplicity and clarity in mind, this library is ideal for students, educators, and developers who want to understand these algorithms line by line. With no external dependencies, no GPU support, and no production overhead, AI4R serves as a practical and transparent way to explore the foundations of AI in Ruby. It is a long-maintained open-source effort to bring accessible, hands-on machine learning to the Ruby community.

forja-enginev0.0.1

RubyGems

This gem contains the core logic for Eiseron Forja, including the DSL parser, the plan/apply workflow, the dependency graph (DAG) builder, and the state management system. It provides the foundational API upon which the CLI and all providers are built.

pikuri-corev0.0.4

RubyGems

pikuri-core is the lean, audit-friendly foundation of the pikuri family: Pikuri::Agent (a thin wrapper around ruby_llm's chat loop) with its Configurator + Extension protocol, the strict Pikuri::Tool framework, a listener surface for rendering / budgets / sub-agents, and four bundled stateless tools (calculator, web search, web scrape, fetch). Extensions (skills, MCP, workspace, coding stack, named-agent personas) live in sibling gems so a privacy-conscious user can install just this core and audit a minimal dependency tree. For the convenience bundle that pulls in everything, see the +pikuri+ metagem.

not_pressed-corev0.1.0

RubyGems

not_pressed-core is the foundational engine behind NotPressed, a fully open-source, batteries-included CMS for Rails 8. It provides hierarchical pages, a block-based content editor, automatic navigation discovery from routes and view partials, a media library backed by Active Storage, a pluggable admin panel with configurable auth, and a content type registry — all built on Hotwire with zero external JS dependencies.
