Overview

Custom Transformer

Allows for implementation of the transform to happen in-line through a block passed to the initializer.

Example:

# This contrived example reverses all string literals
RubyTransform::Transformers::Custom.new do |expression|
  if sexp?(expression) && expression.kind == :str
    s(:str, expression.body[0].reverse)
  else
    super
  end
end
