erl_id_trans
MODULE
MODULE SUMMARY
DESCRIPTION
This module performs an identity parse transformation of Erlang code. It is included as an example for users who may wish to write their own parse transformers. If the 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
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.
Programmers are strongly advised not to engage in parse transformations and no support is offered for problems encountered.
