# morsify | ||
|
||
[![npm-version]][npm] [![travis-ci]][travis] [![coveralls-status]][coveralls] | ||
|
||
Morse code encoder and decoder with no dependencies supports Latin, Cyrilic, Greek, Hebrew, | ||
Arabic, Persian, Japanese, and Korean characters with audio generation functionality. | ||
|
||
```js | ||
var morsify = require('morsify'); | ||
|
||
morsify.encode('SOS'); // .../---/... | ||
morsify.decode('.../---/...'); // S O S | ||
morsify.audio('SOS') // will return base64 encoded audio/wav data | ||
``` | ||
|
||
You can customize the dash, dot or space characters and specify the alphabet with the priority option for | ||
an accurate encoding and decoding. | ||
|
||
What priority option does is, gives direction to the plugin to start to searching for the given character set first. | ||
|
||
Set the priority option according to the list below. | ||
|
||
- 1 => ASCII (Default) | ||
- 2 => Numbers | ||
- 3 => Punctuation | ||
- 4 => Latin Extended (Turkish, Polski etc.) | ||
- 5 => Cyrilic | ||
- 6 => Greek | ||
- 7 => Hebrew | ||
- 8 => Arabic | ||
- 9 => Persian | ||
- 10 => Japanese | ||
- 11 => Korean | ||
|
||
```js | ||
morsify.encode('Ленинград', { priority: 5 }) // .-.././-./../-./--./.-./.-/-.. | ||
morsify.decode('.../.-/--./.-/.--./.--', { priority: 6 }) // Σ Α Γ Α Π Ω | ||
morsify.decode('––– –... ––– –. ––. .. .–.. –––', { dash: '–', dot: '.', space: ' ', priority: 7 }) // ה ב ה נ ג י ל ה | ||
morsify.audio('البُراق', { // generates the morse .-/.-../-.../.-./.-/--.- then generates the audio from it | ||
