Expose elementMatcher function as render() option #61

So that people can use any black magic they wish to bind templates.

Useful e.g. in projects where several people are working on the same HTML code.

Thanks for the feedback. I totally understand the need, based on the IRC discussion.

I think about the API over night, request for comments tomorrow and go for the implementation on Sunday.

Here's the API proposal.

I ended up proposing that the matcher can be given just for one call or for all the calls. The latter is probably the more common scenario.


# Match only by data-bind. Return true, if the element matches to the key.
matcher = (element, key) ->
  element.getAttribute('data-bind') == key

# Use the custom matcher only for this call
$('#template').render data, {}, matcher: matcher

# Use the custom matcher for all the calls in the future
Transparency.config.matcher = matcher

# Matches only by data-bind
$('#template').render data
