Executes a block in the context of an object whose interface represents a DSL.
Example of using an Array as a DSL:
Docile.dsl_eval [] do push 1 push 2 pop push 3 end #=> [1, 3]
@param dsl [Object] an object whose methods represent a DSL @param args [Array] arguments to be passed to the block @param block [Proc] a block to execute in the DSL context @return [Object] the dsl object, after execution of the block
# File lib/docile.rb, line 21 def dsl_eval(dsl, *args, &block) block_context = eval("self", block.binding) proxy_context = FallbackContextProxy.new(dsl, block_context) begin block_context.instance_variables.each { |ivar| proxy_context.instance_variable_set(ivar, block_context.instance_variable_get(ivar)) } proxy_context.instance_exec(*args,&block) ensure block_context.instance_variables.each { |ivar| block_context.instance_variable_set(ivar, proxy_context.instance_variable_get(ivar)) } end dsl end
