@eq: problem with value=false about dustjs-helpers HOT 2 CLOSED

Any helper parameter that is not surrounded by quotes will be considered a reference. Consider this example:

JSON:

{
  "false":"mypropertyWithNameFalse"
}

and template

{@eq key=false type="string" value="mypropertyWithNameFalse"}
same
{:else}
not same
{/eq}

Dust will grab value of false key from context and as a result will render same.

In order for your example to work you'll need to pass in false in as a string and use type="boolean" parameter on eq helper like so:

{@eq key=val value="false" type="boolean"}

In this case values of key and value parameters will be coerced to boolean type and you'll get the result you are looking for.

Alternatively you could do type="string" to convert and compare values as strings. But there seems to be an issue with coerce not coercing falsy values. I think that's a bug and it needs to be fixed.

Unrelated to the problem, but you can write this like:

{#.}
  {^val}
  FALSE
  {:else}
  TRUE
  {/val}
{/.}
