# Ogham
 [](https://badge.fury.io/js/ogham) [](https://coveralls.io/github/evanshortiss/ogham?branch=master)
[](https://github.com/ellerbrock/typescript-badges/)
Converts a given input string to its Ogham equivalent. If you're interested in
learning more about Ogham check out these articles:
* [Ogham on Wikipedia](https://en.wikipedia.org/wiki/Ogham)
* [Ogham by Balldrich Ballbarian](http://www.housebarra.com/EP/ep02/05ogham.html)
As an example, the string `hello` will become `᚛ᚆᚓᚂᚂᚑ᚜` if converted to Ogham.
Typically Ogham is read from bottom to top so our hello example above would
normally be rotated 90 degrees counterclockwise.
The best results are obtained by passing words in their Irish Gaelic form since
the Irish alphabet is missing letters that occur in English and other alphabets.
For example the English word "key" contains the letters 'k' and 'y' which don't
appear in the Irish alphabet so no Ogham character exists for these; instead you
could pass the Irish word "eochair" or pass the `usePhonetics` option to replace
'k' with 'q' and 'y' with 'i'.
*Disclaimer: This module is still in development and results should be checked
against with an Ogham reference such as those on Wikipedia and other
websites*
## JavaScript Example
```js
const ogham = require('ogham')
console.log(ogham.convert('ireland'))
// prints "᚛ᚔᚏᚓᚂᚐᚅᚇ᚜"
```
## TypeScript/ES6 Example
```ts
import * as ogham from 'ogham'
console.log(ogham.convert('ireland'))
// prints "᚛ᚔᚏᚓᚂᚐᚅᚇ᚜"
```
## API
### convert(input: string, options: OghamOptions)
Converts the given input string to its ogham representation. Inputs must be A-Z
characters without accents, e.g pass `a` instead of `á`. Pssing the letters `j`,
`k`, `v`, `w`, `x`, and `y` will cause an error to be thrown unless the
`replaceMissingLetters` option is passed - this is because these letters aren't
present in the Irish alphabet.
Supported keys in the options Object are:
* `addBoundary: Boolean` - Determines if the begging `᚛` and ending `᚜`
characters should be added.
* `useForfeda: Boolean` - This enables use of the
[Forfeda](https://en.wikipedia.org/wiki/Forfeda) characters. For example,
instead of `ea` being printed as `ᚓᚐ` it will be printed as `ᚕ`.
* `usePhonetics` - This setting will replace the following letters with
phonetic equivalents since they don't occur in the Irish alphabet:
* J => G
* K => Q
* V => F
* W => UU
* X => Z
* Y => I
Below are some examples.
#### options.addBoundary
```js
const convertedText = ogham.convert('ireland', {
addBoundary: false
})
console.log(convertedText)
// prints "ᚔᚏᚓᚂᚐᚅᚇ" instead of the default "᚛ᚔᚏᚓᚂᚐᚅᚇ᚜"
```
#### options.usePhonetics
```js
console.log(
ogham.convert('keys', {
usePhonetics: true
})
)
// prints "᚛ᚊᚓᚔᚄ᚜" which is actually "qeis" since 'k' and 'y' need to be
// replaced with phonetically similar characters as they don't appear in the
// irish alphabet https://en.wikipedia.org/wiki/Irish_orthography#Alphabet
