> Handlebars block helper for repeating whatever is inside the block _n_ times.
Please consider following this project's author, [Jon Schlinkert](https://github.com/jonschlinkert), and consider starring the project to show your :heart: and support.
## Install
Install with [npm](https://www.npmjs.com/):
```sh
$ npm install --save handlebars-helper-repeat
```
If you find a bug or have a feature request, [please create an issue](https://github.com/helpers/handlebars-helper-repeat/issues).
## Usage
```js
const repeat = require('handlebars-helper-repeat');
handlebars.registerHelper('repeat', repeat);
```
## Register with handlebars
```js
const handlebars = require('handlebars');
// 2. register the helper, name it whatever you want
handlebars.registerHelper('repeat', require('handlebars-helper-repeat'));
// 3. register some partials
handlebars.registerPartial('button', '{{text}}');
// 4. use in templates
const fn = handlebars.compile('{{#repeat 2}}{{> button }}{{/repeat}}');
console.log(fn({text: 'Click me!'}));
//=> 'Click me!Click me!'
```
## Usage Examples
**Private variables**
A few private variables are exposed to blocks:
* `count` the total number of blocks being generated
* `index` the index of the current block
* `start` the start number to use instead of zero. Basically `index + start`
Example:
```handlebars
{{#repeat count=2 start=17}}
{{> button }}{{@index}}
{{else}}
Nothing :(
{{/repeat}}
```
Results in something like:
```html
Click me!17
Click me!18
```
**Index**
Output the index of the current block:
```handlebars
{{#repeat 2}}
{{> button }}
{{/repeat}}
```
Results in something like:
```html
Click me
Click me
```
