A Morse encoder implemented with good OOP design (imho).

The program encodes a file or a string content in a Morse format.

Encoding

Assuming that Morse code mapping for the following chars:

• "A" => ".-"
• "B" => "-..."
• "1" => ".----"
• "2" => "..---"
• "3" => "..---"

To encode the string "Ab 123", we get the following result:

encoder = Morse::Encoder.new
encoder.encode_text("Ab 123") # => ".-|-.../.----|..---|..---"

From this example, we can note 3 rules used by the encoder:

• The encoder is case insensitive.
• Each encoded character is separated by a |.
• Each encoded word is separated by a /.

Currently, the default Morse code mapping is used: definitions.yml. In order to use a different set of mappings, you can provide them to the Encoder constructor.

my_mappings = { 'A' => '.', 'B' => '..', 'C' => '...'}

encoder = Morse::Encoder.new(my_mappings)
encoder.encode_text("abc") # => ".|..|..."

When encoding a text with line-breaks, they will be kept intact. Ex:

encoder.encode_text("Ab\n123")
# => Results in
# .-|-...
# .----|..---|..---

It's possible to encode a file's content too. For this case you need to pass the file path and you will get back the encoded File object.

encoder.encode_file(filepath) # => encoded `File` object.

Obfuscated Encoding

The encoder has a built-in obfuscated mode. It basically obfuscates the resultant Morse code based on a set of rules. Check DefinitionsObfuscated doc for more info on the rules. Example:

encoder = Morse::EncoderObfuscated.new
encoder.encode_text("ab 123") # => "1A|A3/1D|2C|3B"
encoder.encode_file(filepath) # => encoded `File` object

Commands

It's possible to use the program through a set of command lines. Run rake -T to see the available commands and how to use them.

Testing
