NAME

6       erl_id_trans - An identity parse transform.
7

DESCRIPTION

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

EXPORTS

16       parse_transform(Forms, Options) -> Forms
17
18              Types:
19
20                 Forms = [erl_parse:abstract_form() | erl_parse:form_info()]
21                 Options = [compile:option()]
22
23              Performs an identity transformation on Erlang forms, as an exam‐
24              ple.

PARSE TRANSFORMATIONS

27       Parse transformations are used if a programmer wants to use Erlang syn‐
28       tax,  but  with  different  semantics. The original Erlang code is then
29       transformed into other Erlang code.
30
31   Note:
32       Programmers are strongly advised not to  engage  in  parse  transforma‐
33       tions. No support is offered for problems encountered.
