Converts STEM blocks and inline macros to SVG images using MathJax-node for AsciiDoctor PDF.

An Asciidoctor extension that renders protection-relay time-current grading studies written in the tc-curves language (.ptc source) — the @openpowershift/time-current-grading-language npm package — into SVG or PNG at conversion time. SVG output is vector and embeds cleanly in asciidoctor-pdf; PNG rasterisation ships with the tc-curves package itself, so no extra native dependency is needed. Format, scale, theme, the sheet to draw and error handling are controlled with AsciiDoc attributes.

Ruby gem that randomly generates cat and human ASCII drawings

Zero-dependency terminal recording and playback for Windows. Records sessions with accurate timing, exports to asciicast v2 (compatible with asciinema.org). v0.2.0: Export to GIF/MP4/WebM video (FFmpeg), pure Ruby PPM renderer with embedded VGA font, 9 terminal themes, Rich-Ruby integration, full ANSI color support (16/256/TrueColor).

AsciiPngfy is a Ruby Gem that enables you to render ASCII text into a PNG image up to a resolution of 3840(width) by 2160(height) using a 5x9 monospaced font. Configurable settings that influence the result are font-color, background-color, font-height, horizontal-spacing, vertical-spacing, and text. The result includes the PNG containing the intended image with all the settings applied, a snapshot of the settings used, and render dimensions that define the size the generated png should be rendered at to reflect the font-height settings. The generated png is always the lowest possible resolution. Each monospaced character takes up a 5(width) by 9(height) space to take advantage of scaled rendering and avoid unnecessarily large images. For the best visual results, the resulting png should be rendered in the original dimensions or the render dimensions along with a NEAREST filter.

Learn Enough Ruby palindrome detector

Ruby implementation of the Agent Client Protocol (ACP) — a JSON-RPC standard for agent-editor communication. Includes client (connect to ACP agents), server (host Ruby agents via ACP), and transport layer.

Agent loop, session management, tool execution, context compaction, hooks, and extensions.

The AG-UI (Agent-User Interaction) protocol server for the ask-rb ecosystem — SSE event streaming and the runtime surface that assistant-ui and CopilotKit frontends expect.

Creates and manages the agents an Anychat workspace owns. Anychat gives a business an agent of its own — a page customers can visit, a chat they can talk to, and the words it answers with. This is the client layer only: the tool framing that exposes it to an agent (MCP servers, native Ask::Tools) is provided by the consumers.

A minimal MCP (Model Context Protocol) server that exposes the agents an Anychat workspace owns as callable tools over stdio — list them, read one, bring a new one into being, change one, or retire one. Designed for clients that speak MCP (ZCode, Claude Code, and the like). The tool shell (name, schema, call) lives here, wrapping ask-anychat; the API client itself is that gem's.

Exposes Ask::Agent::Session behind the standard app-server JSON-RPC/stdio protocol. Drop-in compatible with clients that speak the ZCode/Codex app-server protocol — Telegram bots, AI SDK providers, IDE extensions, and headless automation.

Env, file, Rails credentials, database, and OAuth providers. Zero external dependencies.
