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.
