A Lift instance can have any of its values turned into a Template
Haskell expression. This is needed when a value used within a Template
Haskell quotation is bound outside the Oxford brackets ([| ... |]) but not
at the top level. As an example:
add1 :: Int -> Q Exp add1 x = [| x + 1 |]
Template Haskell has no way of knowing what value x will take on at
splice-time, so it requires the type of x to be an instance of Lift.
A Lift instance must satisfy $(lift x) ≡ x for all x, where $(...)
is a Template Haskell splice.
Lift instances can be derived automatically by use of the -XDeriveLift
GHC language extension:
{-# LANGUAGE DeriveLift #-}
module Foo where
import Language.Haskell.TH.Syntax
data Bar a = Bar1 a (Bar a) | Bar2 String
deriving LiftMinimal complete definition
Nothing
Methods
Turn a value into a Template Haskell expression, suitable for use in a splice.
