A very tiny, dependency-free Morse code encoder and decoder. Currently supports the ITU standard.
npm install morse-node
var morse = require('morse-node').create("ITU");
- All alphanumeric characters are accepted, available symbols includes everything inside the brackets [ . , ? ' ! / ( ) & : ; = + - _ " $ @ ].
var msg = morse.encode('The quick brown fox jumped over the lazy dog.');
- Letters are seperated by a single space.
- Words are seperated by a forward slash " / ".
var msg = morse.decode("- .... ./--.- ..- .. -.-. -.-/-... .-. --- .-- -./..-. --- -..-/.--- ..- -- .--. . -../--- ...- . .-./- .... ./.-.. .- --.. -.--/-.. --- --. .-.-.-");
- Check validity of a string by using the isValid function.
- Encoding and decoding functions do not make this check and will attempt to translate your string regardless of undefined characters.
var morse = require('morse-node').create();
var encoded = morse.encode('Pack my box with five dozen liquor jugs!');
console.log(encoded);
var decoded = morse.decode(encoded);
console.log(decoded);
console.log(morse.isValid(encoded, "morse"));
console.log(morse.isValid(encoded += "asdf", "morse"));
console.log(morse.isValid(decoded, "chars"));
console.log(morse.isValid(decoded += "~", "chars"));
