Built-in Helpers

Builtin helpers are helpers that come as part of the Squirrelly library. They can always be overwritten if desired, but they provide simple, no-setup logic within templates.

if/else

{{@if(it.somevalue === 1)}}

Display this

{{#else}}

Display this

{{/if}}

This is a native helper

each

{{@each(it.somearray) => val, index}}

Display this

The current array element is {{val}}

The current index is {{index}}

{{/each}}

Helper References:

• val: the current array element
• index: the index of the array element

Note that val, index are both optional and can be renamed. Ex. => item or => item, number

foreach

{{@foreach(it.someobject) => key, val}}

This loops over each of an objects keys and values.

The value of the current child is {{val}}

The current key is {{key}}

{{/foreach}}

Helper References:

• key: the key of the current object child
• val: the value of the current child

Note that val, index are both optional and can be renamed. Ex. => item or => item, number

try-catch

{{@try}}

This won't work: {{ *it.hi | validate}}

{{#catch => err}}

Uh-oh, error! Message was '{{err.message}}'

{{/try}}

Helper References:

• err: the error
