The transformers-compat package

[Tags:bsd3, library]

This package includes backported versions of types that were added to transformers in transformers 0.3, 0.4, and 0.5 for users who need strict transformers 0.2 or 0.3 compatibility to run on old versions of the platform, but also need those types.

Those users should be able to just depend on transformers >= 0.2 and transformers-compat >= 0.3.

Note: missing methods are not supplied, but this at least permits the types to be used.

Hackage Build Status

This provides a thin compatibility shim on top of transformers-0.2 to add the types that were added in transformers-0.3.

This enables users to maintain haskell-platform compatibility, while still gaining access ot the new functionality.
