CW

CW is a program for learning and practicing Morse Code (CW). It is written in the form of a DSL in the Ruby language.

CW can read books (and remember where you are), rss feeds (your daily quotation for instance), common phrases, QSO codes etc, in addition to generating random words, letters, and numbers that possibly match some required pattern (i.e. words_beginning_with 'v').

CW also allows for real-time progress marking by indicating correct and incorrect characters and words copied in real-time. A follow mode also exists which prints the output just after it has played it (for `in head' practice).

CW is thoroughly documented, and includes a hands-on tutorial.

Installation:

gem install cw
cw example.rb

Note:

• Requires Ruby 2+
• Tested on OS X, and Linux. A Vagrantfile is available in the root directory.
