Template language similar to examples

Hi,

I would like to process a text file which contains property-tokens which
are replaced appropiately by the template processing library.
Property-tokens can be single value, or can be collection of values.

The format I would like to use is something like this (the specific
characters used to signal might be different):

#!This is a comment
#DECLARE(%myProperty) #!Here I declare a property (variable) for
                        #!use within the template
#DECLARE(%myCollection),MULTI #!This would be an array collection
#SET(%mySymbol,1) #!assign a value of 1
#ADD(%myCollection,'A') #!add something to the collection
#ADD(%myCollection,'B') #!add something to the collection
#ADD(%myCollection,'C') #!add something to the collection

#!The code that goes below goes straight into the output,
#!except that it takes into account how the #IF is evaluated.
class myTestClass
def initialize
  #IF(%mySymbol = 1)
  @msg = 'Test1'
  #ELSE
  @msg = 'Test2'
  #ENDIF
    #INSERT(%myTemplateProcedure,%myCollection)
end
end

#GROUP(%myTemplateProcedure,%pCollection)
#!For this example, the code below generates:
#! @msgA = 'A'
#! @msgB = 'B'
#! @msgC = 'C'
#!Not very useful, but serves as an example of the things I'm looking
for.
   #FOR(%myCollection)
@msg%myCollection = '%myCollection'
   #ENDFOR

The output would be:

class myTestClass
def initialize
  @msg = 'Test1'
    @msgA = 'A'
    @msgB = 'B'
    @msgC = 'C'
end
end

Are any of you guys familiar with a library that will do something
similar to the above?

Thanks,
Edgard

Wow. Couldn't you just use ERB?

  require 'erb'

  my_symbol = 1
  my_collection = ['A', 'B', 'C']
  my_template_proc = lambda do |coll|
    coll.map { |a| "@msg#{a}" }.join(', ') + " = #{coll.inspect}"
  end

  e = ERB.new <<-EOF
    class MyTestClass
      def initialize
        <% if my_symbol %>
        @msg = 'Test1'
        <% else %>
        @msg = 'Test2'
        <% end %>
        <%= my_template_proc.call(my_collection) %>
      end
    end
  EOF

  puts e.result
