handlebars-repeat

This crate provides a [handlebars] helper function which repeats a block a given number of times (the count). For example:

notrust {{#repeat 3}} hi {{/repeat}}

Produces:

notrust hi hi hi

Local Variables

Within the repeated block, there are three local variables in addition to the standard context:

1. @index is an integer indicating the index of the current repetition.
2. @first is a boolean indicating whether this is the first repetation.
3. @last is a boolean indicating whether this is the last repetation.

For example:

notrust {{#repeat 3}} Index: {{@index}} (first: {{@first}}; last: {{@last}}) {{/repeat}}

Produces:

notrust Index: 0 (first: true; last: false) Index: 1 (first: false; last: false) Index: 2 (first: false; last: true)

Inverse Block

Like the standard each helper function, repeat can specify an inverse block which will be rendered when count == 0. For example:

notrust {{#repeat 0}} foo {{else}} bar {{/repeat}}

Produces:

notrust bar
