transformers-compat: A small compatibility shim exposing the new types from transformers 0.3 and 0.4 to older Haskell platforms.

[ 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.

Enabled
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, but keeps the package Haskell 98.

Enabled

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

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.
