    Ember Truth Helpers Build Status

    HTMLBars template helpers for additional truth logic in if and unless statements.

    Installation

    ember install ember-truth-helpers
    

    Usage

    Helper JavaScript HTMLBars Variable argument count allowed
    eq if (a === b) {{if (eq a b)}} No
    not-eq if (a !== b) {{if (not-eq a b)}} No
    not if (!a) {{if (not a)}} Yes
    and if (a && b)* {{if (and a b)}} Yes
    or if (a || b) * {{if (or a b)}} Yes
    xor if (a && !b || !a && b)* {{if (xor a b)}} No
    gt if (a > b) {{if (gt a b)}} No
    gte if (a >= b) {{if (gte a b)}} No
    lt if (a < b) {{if (lt a b)}} No
    lte if (a <= b) {{if (lte a b)}} No
    is-array if (Ember.isArray(a)) {{if (is-array a)}} Yes
    is-empty if (Ember.isEmpty(a)) {{if (is-empty a)}} No
    is-equal if (Ember.isEqual(a, b)) {{if (is-equal a b)}} No
    * Unlike their JavaScript counterparts, these expressions do not short circuit. For example, with (or a b), even if a is truthy, b will still be evaluated. See this explanation.

    API

    is-equal

    is-equal uses Ember.isEqual helper to evaluate equality of two values. eq should be sufficient for most applications. is-equal is necessary when trying to compare a complex object to a primitive value.
