transformers-compat: A small compatibility shim for the transformers library

[ bsd3, compatibility, library ] [ Propose Tags ]

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.

Flags

Manual Flags

NameDescriptionDefault
two

Use transformers 0.2. This will be selected by cabal picking the appropriate version.

Disabled
three

Use transformers 0.3. This will be selected by cabal picking the appropriate version.

Disabled
four

Use transformers 0.4. This will be selected by cabal picking the appropriate version.

Enabled
five

Use transformers 0.5 up until (but not including) 0.5.3. This will be selected by cabal picking the appropriate version.

Disabled
mtl
  • f-mtl Disables support for mtl for transformers 0.2 and 0.3. That is an unsupported configuration, and results in missing instances for ExceptT.

Enabled
generic-deriving
  • f-generic-deriving prevents generic-deriving from being built as a dependency. This disables certain aspects of generics for older versions of GHC. In particular, Generic(1) instances will not be backported prior to GHC 7.2, and generic operations over unlifted types will not be backported prior to GHC 8.0. This is an unsupported configuration.

Enabled

Use -f <flag> to enable a flag, or -f -<flag> to disable that flag. More info

transformers-compat

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.
