min / max

Accept either multiple arguments or an array:

{{ min(10, 5, 20) }}       → 5
{{ max(10, 5, 20) }}       → 20
{{ min(prices) }}           → smallest in array
{{ max(prices) }}           → largest in array

random

Returns a random value. Without arguments, returns a random number. With an array, returns a random element:

{{ random() }}
{{ random(['red', 'green', 'blue']) }}

range

Generates a sequence of numbers:

{{ range(1, 5) }}           → [1, 2, 3, 4, 5]
{{ range(0, 100, 10) }}     → [0, 10, 20, ..., 100]

cycle

Cycles through an array based on an index — useful in loops for alternating values:

{{ cycle(['odd', 'even'], loop.index) }}
{{ cycle(['primary', 'secondary', 'accent'], loop.index) }}

date

Creates a timestamp value that can be formatted with the date filter:

{{ date()|date('Y-m-d') }}
{{ date('now')|date('F j, Y') }}

html_classes

Generates a space-separated class string. Strings are always included, objects include the key only when the value is truthy:

{{ html_classes('btn', {active: is_active, disabled: is_disabled}) }}

If is_active is true and is_disabled is false, the output is btn active.
