Derive Template Haskell's @Lift@ class for datatypes using @TemplateHaskell@. The functionality in this package has largely been subsumed by the @DeriveLift@ language extension, which is available in GHC 8.0 and later versions. As such, this package is only useful as a way to backport bugfixes to @DeriveLift@ in later GHC versions back to older GHCs. . The following libraries are related: . * The <https://hackage.haskell.org/package/th-orphans th-orphans> package provides instances for @template-haskell@ syntax types. . * The <http://hackage.haskell.org/package/th-lift-instances th-lift-instances> package provides @Lift@ instances for types in @base@, @text@, @bytestring@, @vector@, etc. Some of these instances are only provided for old versions of their respective libraries, as the same @Lift@ instances are also present upstream on newer versions.
This is a Haskell library to derive Template Haskell's Lift class for datatypes.
