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.

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 gem can compare HTML and assert certain elements exists. This is useful when writing tests.

Sprockets is a Rack-based asset packaging system that concatenates and serves JavaScript, CoffeeScript, CSS, LESS, Sass, and SCSS.

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

This Ruby library integrates SassC-Ruby into Rails.

This package provides a toolkit for building modeling frameworks like Active Record. ActiveSupport handles attributes, callbacks, validations, serialization, internationalization, and testing.

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.

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.

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.

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

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.

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

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

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

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.

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.

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.

rdesktop is a client for Microsoft's Windows Remote Desktop Services, capable of natively speaking Remote Desktop Protocol (RDP). It allows users to remotely control a user's Windows desktop.

Xrdp provides a graphical login to remote machines using Microsoft Remote Desktop Protocol (RDP). Xrdp accepts connections from a variety of RDP clients:

• FreeRDP

• rdesktop

• KRDC

• NeutrinoRDP

• Windows MSTSC (Microsoft Terminal Services Client, aka mstsc.exe)

• Microsoft Remote Desktop (found on Microsoft Store, which is distinct from MSTSC).

CLucene is a high-performance, scalable, cross platform, full-featured indexing and searching API. It is a port of the very popular Java Lucene text search engine API to C++.
