# merl\_transform(3erl)

Parse transform for merl.

## NAME

merl\_transform - Parse transform for merl.

## DESCRIPTION

Parse transform for merl. Enables the use of automatic metavariables and using quasi-quotes in matches and case switches. Also optimizes calls to functions in *merl* by partially evaluating them, turning strings to templates, etc., at compile-time.

Using *-include\_lib("syntax\_tools/include/merl.hrl").* enables this transform, unless the macro *MERL\_NO\_TRANSFORM* is defined first.

## EXPORTS
