This library integrates the SASS stylesheet language into Ruby on Rails.

The With advisory lock gem adds advisory locking to ActiveRecord for PostgreSQL and MySQL. SQLite is also supported, but this uses the file system for locks.

This package provides a modest JavaScript framework for the HTML you already have.

Provides Sprockets implementation for the Rails Asset Pipeline.

GlobalID provides a way to generate URIs from a model in Ruby that uniquely identify it.

This gem is used to handle HTML sanitization in Rails applications. If you need similar functionality in non Rails apps consider using Loofah directly.

ActiveSupport is a toolkit of support libraries and Ruby core extensions extracted from the Rails framework. It includes support for multibyte strings, internationalization, time zones, and testing.

This package provides a Ruby wrapper for the MRI 2.0 debug_inspector API.

railties provides the core Rails internals including handling application bootup, plugins, generators, and Rake tasks.

Import maps can import JavaScript modules using logical names that map to versioned/digested files -- directly from the browser. It makes it possible to build modern JavaScript applications using JavaScript libraries made for ES modules (ESM) without the need for transpiling or bundling, which removes the need for Webpack, Yarn, npm, or any other part of the JavaScript toolchain. All that is needed is the asset pipeline that is already included in Rails.

Ruby on Rails is a full-stack web framework optimized for programmer happiness and sustainable productivity. It encourages beautiful code by favoring convention over configuration.

Compose, deliver, receive, and test emails using the controller/view pattern. Including support for multipart email and attachments.

ActionPack provides conventions for building and testing MVC web applications. These work with any Rack-compatible server.

Active Record connects classes to relational database table to establish an almost zero-configuration persistence layer for applications.

This package provides a bootloader for the ARM part of a Raspberry Pi. Note: It does not work on Raspberry Pi 1.

This package provides a C library for Broadcom BCM 2835 as used in the Raspberry Pi

This package provides a bootloader for the ARM part of a Raspberry Pi. Note: It does not work on Raspberry Pi 1.

This package package contains libraries to interface to EGL, mmal, GLESv2, vcos, openmaxil, vchiq_arm, bcm_host, VFC and OpenVG. It also provides the dtmerge, dtoverlay, dtparam, raspivid and tvservice commands, among others.

This package contains device tree overlay binaries to support the WaveShare SpotPear TFT LCDs on the Raspberry Pi.

The fbcp command provided by this package can be used to copy the primary frame buffer to the secondary frame buffer of a Raspberry Pi. It can for example mirror the primary HDMI output to a secondary LCD display connected to the Raspberry Pi board.

rpi-imager is graphical utility to easily provision and flash a memory card with an operating system image suitable for the Raspberry Pi single board computer.

Tool to help debug / hack at the BCM283x GPIO. You can dump the state of a GPIO (or all GPIOs). You can change a GPIO mode and pulls (and level, if set as an output). Beware that this tool writes directly to the BCM283x GPIO registers, ignoring anything else that may be using them (like Linux drivers).

Ratpoison is a simple window manager with no fat library dependencies, no fancy graphics, no window decorations, and no rodent dependence. It is largely modelled after GNU Screen which has done wonders in the virtual terminal market.

The screen can be split into non-overlapping frames. All windows are kept maximized inside their frames to take full advantage of your precious screen real estate.

All interaction with the window manager is done through keystrokes. Ratpoison has a prefix map to minimize the key clobbering that cripples Emacs and other quality pieces of software.

The rcm suite of tools is for managing dotfiles directories. This is a directory containing all the .*rc files in your home directory (.zshrc, .vimrc, and so on). These files have gone by many names in history, such as “rc files” because they typically end in rc or “dotfiles” because they begin with a period. This suite is useful for committing your rc files to a central repository to share, but it also scales to a more complex situation such as multiple source directories shared between computers with some host-specific or task-specific files.
