• IC-705

• IC-905

• IC-7300

• IC-7610

• IC-7850

• IC-7851

• IC-9700

convert-samples is a command-line program to convert samples received from software defined radios from one format to another.

Supported formats:

• s8: signed 8 bit integer

• u8: unsigned 8 bit integer

• s16: signed 16 bit integer

• u16: unsigned 16 bit integer

• s32: signed 32 bit integer

• u32: unsigned 32 bit integer

• f32: 32 bit float

• cs8: complex made of signed 8 bit integers

• cu8: complex made of unsigned 8 bit integers

• cs16: complex made of signed 16 bit integers

• cu16: complex made of unsigned 16 bit integers

• cs32: complex made of signed 32 bit integers

• cu32: complex made of unsigned 32 bit integers

• cf32: complex made of 32 bit floats

Flrig is a transceiver control program for amateur radio use. It provides computer aided control of various radios using a serial or USB connection.

This program is a software-defined receiver which is able to process (that is, to perform detection, synchronization, demodulation and decoding of the navigation message, computation of observables and, finally, computation of position fixes) the signals of the BeiDou, Galileo, GLONASS and GPS Global Navigation Satellite System.

Ragel compiles executable finite state machines from regular languages. Ragel targets C, C++, Obj-C, C#, D, Java, Go and Ruby. Ragel state machines can not only recognize byte sequences as regular expression machines do, but can also execute code at arbitrary points in the recognition of a regular language. Code embedding is done using inline operators that do not disrupt the regular language syntax.

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.

This package provides support for using RSpec to test Ruby on Rails applications, in pace of the default Minitest testing library.

marcel provides MIME type detection using magic numbers, filenames, and extensions

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

ActiveStorage integrates file storage services with Rails applications, allowing files to be attached to ActiveRecord models.

ActionView provides conventions and helpers for building web pages in Ruby.

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.

This Ruby library integrates SassC-Ruby into Rails.

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

ActiveJob allows declaring job classes in a common way across Rails applications.

Propshaft is an asset pipeline library for Rails. It's built for an era where bundling assets to save on HTTP connections is no longer urgent, where JavaScript and CSS are either compiled by dedicated Node.js bundlers or served directly to the browsers, and where increases in bandwidth have made the need for minification less pressing. These factors allow for a dramatically simpler and faster asset pipeline compared to previous options, like Sprockets.

Action Cable integrates WebSockets with Rails applications. Through WebSockets it allows for real-time features in web applications.

ActionMailbox receives and processes incoming emails in Rails applications.

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.

ActionText edits and displays rich text in Rails applications.

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

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

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.
