Hackage Hackage Dependencies Haskell Programming Language Build Status

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 th-orphans package provides instances for template-haskell syntax types.

  • The 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.
