This repository is a monorepo for `driver.js`, a lightweight, zero-dependency JavaScript library for creating product tours, feature highlights, and contextual hints on web pages. The core library is in `packages/driver/` and exports two main factories: `driver()` for guided tours with an overlay cutout and popover, and `hints()` for persistent beacon-style hints. The architecture follows an instance-based pattern where each driver or hints instance owns its configuration, state, and event emitter, avoiding global state. Key modules include a pure-geometry positioning system (`position.ts`), an SVG overlay with animated stage transitions (`overlay.ts`, `stage.ts`), a popover renderer shared between tours and hints (`popover.ts`), and capture-phase click handling with `WeakMap`-based listeners (`click.ts`). The library has no runtime dependencies, comprehensive test coverage (vitest + jsdom), and supports keyboard navigation, animation, theming via CSS custom properties, and lifecycle hooks. The monorepo also includes two Astro-based applications: `apps/docs` (documentation site with live code samples) and `apps/playground` (interactive examples). The codebase demonstrates strong engineering practices with clean abstractions, instance isolation, and reusable primitives.
NUR (Nix User Repository) is a community package registry and distribution layer for Nix. In production it maintains a registry of several hundred user-contributed Nix repositories in repos.json, pins every entry to a specific revision in repos.json.lock, and exposes the aggregate as a Nix flake/overlay/package set. The Nix entry points (default.nix, flake.nix, lib/evalRepo.nix, lib/repoSource.nix) lazily translate locked registry entries into `nur.repos.<name>.<pkg>` attributes, including typed support for NixOS, Home Manager, Darwin, and flake-parts modules and overlays via flake-parts. The operational core is a small, typed Python CLI (`bin/nur` and `ci/nur/`) with subcommands for updating the lockfile, evaluating repos, formatting the manifest, generating a combined monorepo, and producing a search index. Updates run hourly via GitHub Actions: each repo is concurrently prefetched using either the Git smart HTTP protocol or GitHub/GitLab archive endpoints, evaluated in a sandboxed `nix-env` run to catch breakage, and then either locked to a new revision or pruned from the registry if deleted. A separate set of CI scripts publishes `nur-combined` and updates package search data. The architecture is cleanly split between Nix expression logic and Python automation, with careful handling of async concurrency, evaluation failures, and safety guards against accidental mass repository loss.
This repository contains documentation and hardware resources for the BIGTREETECH CB1 single-board computer. It does not include executable software but provides comprehensive setup instructions for two system images: a Klipper-based 3D printing firmware and a minimal Armbian Linux system. The documentation covers WiFi configuration, hardware overlays (e.g., WS2812 LED, TFT35 display, MCP2515 CAN bus), eMMC flashing procedures, and detailed GPIO pinout mappings. The repository serves as a reference guide for hardware configuration and system initialization rather than a deployable application.
