Strings now repeat according to length

[JulianBirch]

Imagine you're working on

(render "{{#x}}0{{/x}}" { :x "hello" })

This prints "XXXXX". I'm inclined to think that it should print "X", and I imagine the equivalent code does in ruby (don't have it to hand). I'll send through a pull if we agree it's a bug.

I'm not so sure, to me this looks like you want it to loop over the string hello. But both the Ruby and JS implementations print it just once, so I don't mind doing it the same way.

I also stumbled upon this. Since the mustache manual says about sections that "When the value is non-false but not a list, it will be used as the context for a single rendering of the block", I would expect to have the string printed only once.

I actually use {{#x}}{{.}}{{/x}} with { :x "some string" } quite often to check whether a key exists and if so, print it (and do something else if it doesn't). The only alternative I can think of is to extend the context with something like { :has-x true } for every relevant key :x, but this seems quite tedious...

Think ultimately the problem is that ruby doesn't expose string as a sequence, and Clojure does.

A small workaround for now, wrap your Strings in an Object:

(defn- string-object
  "Wraps a String in an Object that returns the given String when
  .toString is called. Wrapping a String like this prevents clostache
  seeing a String as a collection."
  [s]
  (when s
    (reify Object
      (toString [this] s))))

This turns the String into expected behaviour, just like Ruby, JavaScript and Java.
