Access array value by index in template

[ogdenwebb]

Some implementations(at least js) of Mustache allow to access array value by index, like that.

{{ animals.1 }}

Is there a way to achieve it with moustachu.nim? If no, would you add this?

Hi there @ogdenwebb! So javascript can get away with this because:

var a = [1,2,3];
a[0] // 1
a["0"] // 1 

i.e. an array is just an object (sort of ;) ).

This is not the case in Nim:

var a = @[0,1,2]
a["0"] # breaks
a[0]

In any case, since the official spec doesn't support it, it is not something moustachu will support. Typically, you would store the array element you want to access individually in a separate key. Then you would call it via its key, like any other element.

Thanks for the answer.

My JSON file has enough array data, which I would have access, so that isn't best solution for me in this case.

Well, close then.
