Documentation

type TransformM = StateT TransformState (WriterT (DList Text) (Either Error)) Source #

The monad stack used during transformation:

StateT TransformState to keep track of whether to render the next line tag, the module's name etc.
WriterT (DList Text) to collect the output lines. Instead of haskell's built-in list type we use DList because of it's O(1) append operation.
Either Error to return errors.
