We found some old Handlebars templates which are working fine, but include some odd usage of Handlebars.

The two strange ones are

{{^is_question}}{{/is_question}}

and

{{& answer}}

Neither of those are listed in the Handlerbars docs and there are no helpers defined.

Anyone know what they do?

The ^is_question appears to be used interchangeably with {{#if is_question}}. Maybe it is some deprecated shorthand notation?

The template is piled the same way we pile other templates:

template = Handlebarspile(ItemTemplate)

Our handlebars version is:

Handlebars.VERSION = "1.0.0-rc.3";

• I don't recognize this either. Is it possible someone had a custom task to translate this notation into true handlebars? – runspired Commented Nov 19, 2014 at 20:56
• use of ^ seems to be taken from Mustache templating – jagershark Commented Mar 11, 2016 at 15:15

I've used ^ relatively recently, but I had to look up &:

{{^ question}} X {{/question}} => inverse selection, i.e. if (! question ) X;
{{& answer}} => unescaped, typically: {{{answer}}}
