Passing Arrays or Objects to Helpers

[doc987]

In addition to passing strings, numbers, and boolean values, could it be possible to pass arrays or objects to helpers? For example:

{{helper_function "abc" 10 ["a","b","c"] ["d","e","f"] {"a":1,"b":2,"c":3} true}}

The easiest way is to

• create a custom helper (e.g. arr) that returns an array from a dynamic lists of param (be sure to omit the last argument, because this is the options-object)
• Call this helper as in {{helper_function "abc" 10 (arr "a" "b" "c") ... }}`

I have created an example here: https://jsfiddle.net/9D88g/618/

Somewhat more typing than an array literal, but works okay. Any suggestions for an object literal?

@wycats wants a formal spec of the existing language before adding new language features (#1277). But currently, nobody is really working on one, so I don't see any progress on this in the near future.

Same concept as nknapp's answer for arrays but return the options.hash

I ended up going with a json-parse helper and doing {{helper_function (json-parse "[\"a\",\"b\",\"c\"]")}}. Worked well for me because I'm programmatically generating the templates.

You can use the toArray helper in wirechunk/handlebars-helpers if you don't want to write a helper function yourself but can install a library. 😃
