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}}



{{/repeat}}
`

Results in something like:

`html


Click me

`
