NAME

       erl_id_trans - An identity parse transform.

DESCRIPTION

       This  module  performs  an identity parse transformation of Erlang code. It is included as an example for
       users who wants to write their own parse transformers. If option {parse_transform,Module}  is  passed  to
       the  compiler,  a  user-written  function  parse_transform/2 is called by the compiler before the code is
       checked for errors.

EXPORTS

       parse_transform(Forms, Options) -> Forms

              Types:

                 Forms = [erl_parse:abstract_form() | erl_parse:form_info()]
                 Options = [compile:option()]

              Performs an identity transformation on Erlang forms, as an example.

PARSE TRANSFORMATIONS

       Parse transformations are used if a programmer wants to use Erlang syntax, but with different  semantics.
       The original Erlang code is then transformed into other Erlang code.

   Note:
       Programmers  are  strongly  advised  not  to  engage  in parse transformations. No support is offered for
       problems encountered.
