Add a 'getkey' helper

[villesiltala]

Add a core helper that prints out a value from an array or an object by the passed key. The syntax could be as follows:

{@getkey map=array/object key=key /}

If the key is no set, an empty string is printed.

Can you elaborate a bit what do you mean with this?

[villesiltala]

This enables you to dynamically get a value from an object.

Print out a string:

{my_string}

Print out a value from an object with the string as the key:

{@getkey map=my_object key=my_string /}

This is against Dust philosophy. We will not implement a dynamic key getter. If you need this kind of logic, there is something wrong with you and your model structure. ;)

Not implemented.
