Duel runs your benchmarks on two versions of your code side by side, the baseline (where your branch left main, say) and the candidate, and fails if the candidate is slower at any of them. Timings are judged by a distribution-free confidence interval for paired CPU-time ratios and confirmed in fresh processes, so it fails on real regressions, not noise.

Mirrors each folder of your NAS shares onto one of several independently mounted drives, tracks where everything lives in a SQLite manifest with a grace period before deletions, and writes an HTML status dashboard with SMART health.

Echoes is a pure-Ruby macOS terminal emulator with first-class integrations for rubish (in-process shell) and rvim (in-process vim editor) panes, plus a private OSC namespace for in-pane Ruby tools that want to drive UI features (gradient backgrounds, rectangular fills, proportional-font text) other terminals can't. Written in pure Ruby on top of AppKit via Fiddle.

ActiveRecord-like prístup k Edupage - školy, žiaci, rozvrhy, domáce úlohy a známky - vystavený zhodne cez Ruby API, CLI, REST API a MCP server. Iba na čítanie.

A llama.cpp plugin for elelem.

ErdMap visualizes key models and associations in Rails applications, helping you understand their architecture by starting with the most important models and allowing zoom-in exploration.

An unopinionated library for obtaining configuration, data, cache, & other directories. Etcetera supports the XDG base directory specification, Apple's Standard Directories, Windows' Known Folder Locations, and the Unix single-folder convention, and lets you choose which to follow.

fatty is a pure Ruby curses-backed terminal interaction library with editable single-line input, scrollable output, and programmable keybindings, inspired by modern shells like fish.

CLI Templating System and String Formatter

Generate SEPBLAC FTF valid files from a json

Get Google News headlines from Ruby or the command line.

Transport-independent controllers, routing, middleware, configuration and testing for Gritz.

Hank manages symlinks between source paths and flattened pathnames within a git repository, making it easier to manage configuration files and collaborate with AI tools.

Algebraic data types and Haskell pattern syntax for Ruby. Clauses are compiled once into a decision tree by a Rust extension (via Rutie) and checked for exhaustiveness and redundancy, so every logical path is accounted for before the first call.

Generate self-contained async and blocking Rust clients from saved HaveAPI descriptions.

Render Markdown and static SVG previews with the Zaniah renderer.

Booleans, numerics, exact decimals, UUIDs, and temporals cast from untrusted text by a native Rust core — every parse returns a verdict (the value, or a reason plus the offending span), never an exception for bad data. Two backends behind one surface, selected automatically and both shipped prebuilt: a Magnus extension where a precompiled platform gem matches, and stdlib Fiddle everywhere else. No runtime bridge, no dependencies beyond Fiddle.

CSV, TSV and any single-byte ASCII separator, and XLSX, ODS and Numbers workbooks, read by a native Rust core into typed column batches. The core owns no memory: this gem allocates the buffers once and the core fills them in one native call per batch. Every cell is a HyperCast verdict — the value, or a reason plus the offending span — and a file that is not rows of cells at all is an exception raised after the intact rows. Two backends behind one surface, selected automatically and both shipped prebuilt: a Magnus extension where a precompiled platform gem matches, and stdlib Fiddle everywhere else. No compile on install.

RFC 9562 UUID v4 (random), v5 (deterministic) and v7 (time-sortable) generation, with batch and raw-bytes forms and a version 8 SQL Server order for v7, from one native Rust core. Two backends behind one surface, selected automatically and both shipped prebuilt: a Magnus extension where a precompiled platform gem matches, and stdlib Fiddle everywhere else. No runtime bridge, no dependencies beyond Fiddle.
