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

The ammeter gem makes it easy to write specs for Rails generators. An existing user is rspec-rails, which uses ammeter to spec its own generators.

This package allows you to create an interactive Ruby session in your browser. Those sessions are launched automatically in case of an error and can also be launched manually in any page.

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.

Turbo aims to be as fast as single-page web application without having to write any JavaScript. Turbo accelerates links and form submissions without requiring server-side changes to the generated HTML. It allows carving up a page into independent frames, which can be lazy-loaded and operated as independent components. Finally, it helps making partial page updates using just HTML and a set of CRUD-like container tags. These three techniques reduce the amount of custom JavaScript that many web applications need to write by an order of magnitude. And for the few dynamic bits that are left, Stimulus can be used.

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.

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.

Bootsnap is a library that plugs into Ruby, with optional support for YAML, to optimize and cache expensive computations.

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

This gem provides Ruby and Ruby on Rails integration with Autoprefixer, which can parse CSS and add vendor prefixes to CSS rules using values from the Can I Use website.

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

This Ruby library integrates SassC-Ruby into Rails.

Spring is a Ruby on Rails application preloader. It speeds up development by keeping your application running in the background so the application does need to boot it every time you run a test, rake task or migration.

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.

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

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.

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).

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

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

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.

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.

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.

FreeRDP implements Microsoft's Remote Desktop Protocol. It consists of the xfreerdp client, libraries for client and server functionality, and Windows Portable Runtime (WinPR), a portable implementation of parts of the Windows API.

xorgxrdp is a collection of modules to be used with a pre-existing X.Org install to make the X server act like X11rdp. Unlike X11rdp, you don't have to recompile the whole X Window System. Instead, additional modules are installed to a location where the existing Xorg installation would pick them.
