Subject: Erb location of exception in template

Hiya!

Does anyone know how I can find the location in an Erb template file
of a line that caused an exception?

The result of calling erb.result(binding) in build.rb looks like this:

./dgp_api.rb:199:in `type': ArgumentError (ArgumentError)
        from (erb):285:in `interpret'
        from (erb):285:in `each'
        from (erb):285:in `interpret'
        from build.rb:26:in `interpret'
        from build.rb:41


I want to know which template line caused the exception in dgp_api.rb.
If this can't be done with erb, can it be done with eruby or erubis?
