Module Summary

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

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.
