[erlang-questions] pushing a dict in the constant pool

[Björn-Egil Dahlberg]

Hi,

Generate a module on the fly, compile and load it.

Something like,

new(Module, Terms) ->
   Forms = [{attribute,1,module,Module},
          {attribute,2,export,[{data,0}]},
          {function,3,data,0,[{clause,4,[],[], 	
	[erl_parse:abstract(Terms)]}]}],

     {ok, Module, Code} = compile:forms(Forms, []),
     {module,Module} = code:load_binary(Module, Module, Code),
     Module.

Use,

new(my_module, SomeDict).

my_module:data() -> SomeDict.
