access array item by index

[gibatronic]

hi! is there a way to access an array item by its index position? this way it doesn't seems to work:

require 'mustache'

data = {
  collection: [{
    title: 'one'
  }, {
    title: 'two'
  }, {
    title: 'three'
  }]
}

template = '{{collection.0.title}}'

puts Mustache.render template, data

I expect one to be printed, but I only get an empty string.

Hello!
As far as I know that syntax is not valid per Mustache spec, so it is not implemented.

@locks It's not invalid, either.

This is more of an "implementations should do what makes sense in the host language" sort of call. In PHP and JavaScript, this…

$collection[0]['title']

is how you would access the title property of the first value in an array called $collection. This…

$collection[0]['title']

… is how you'd access the title property of the value at the '0' key of a hash called $collection.

So in both of those languages, it would be surprising if you couldn't access array elements by index.

So that template works in mustache.php?

[bobthecow]

Yep. And mustache.js

Hm. I'm not sure I like that, makes the behaviour variable from implementation to implementation.

[bobthecow]

I wouldn't recommend it, since accessing things by array index feels like it violates the spirit of mustache to me. But it's possible :)

hm... okay then! thanks guys! I'll parse it before hand and give everything ready to Mustache.
