th-to-exp: Provides a way to persist data from compile-time to runtime.
This package provides a way to persist data from compile-time to runtime by
producing Template Haskell expressions that evaluate to particular values. For
example, if you have a value Just 1
, then toExp (Just 1)
will produce the
expression [e| Just 1 |]
, which can be used in a splice. For a more direct
example, here’s what that looks like without the quasiquote notation:
>>>
toExp (Just 1)
AppE (ConE GHC.Base.Just) (LitE (IntegerL 1))
This is done by using a typeclass, ToExp
, that can be automatically derived
for types that have a Generic
instance.
