Revision history for dep-t

0.6.4

• Added AccumConstructor, a generalization of Constructor that threads a monoidal summary along with the environment record.

• Now Dep.Env.Phased.traverseH and related functions provide a 'Typeable' constraint on the polymorphic field variable in the function argument.

  This should be backwards compatible because, with the 'Typeable' constraint, the HOF is providing more info to the caller of 'traverseH' to work with.

  However it does cause a little breakage, because now you can't use FunctorT, TraversableT and ApplicativeT from the "barbies" library to implement Phased. But most of the time you would use Phased's own generic deriving anyway.

0.6.3

• Now the Bare typeclass doesn't recurse inside Identity or Const.

  Strictly speaking, this is a breaking change, but the cases in which it breaks are very unlikely in practice: when using Identity or Const in the middle of a sequence of phases. Typically, these two applicatives will be used as the colophon of the sequence of phases.

  The motivation for the change is that letting Bare "peek" inside Identity and Const made it difficult to write fromBare-using functions polymorphic on the returned component. Bare got stuck on the component type variable and the functions did not compile. This led to unnecessary code duplication. Stopping at Identity means Bare never touches the type variable and doesn't get stuck.

0.6.2

• Moved fromBare and toBare from dep-t-dynamic.

• Doc fix by @eyeinsky (PR #20)

0.6.1.0

• Re-export Data.Functor.Constant from Control.Monad.Dep. https://github.com/danidiaz/dep-t/issues/18

0.6.0.0

• Added module Dep.Tagged.

• Changed the Constructor type synonym.

  Now it takes a fully constructed environment type.

  This is a backwards-incompatible change. Type signatures might need to be modified, not so much term level code.

  https://github.com/danidiaz/dep-t/issues/17

• Removed deprecated modules.

0.5.1.0

• Control.Monad.Dep.Has and Control.Monad.Dep.Env renamed as Dep.Has and Dep.Env.

  The old modules still remain, but deprecated.

0.5.0.0

• Phased now has Typeable constraints. Should be a mostly backwards compatible change, as Typeable instances are automagically generated for most types.

  Motivated by https://github.com/danidiaz/dep-t-dynamic/issues/1

0.4.6.0

• added new module Control.Monad.Dep.Env with helpers for defining environments of records.

0.4.5.0

• added "asCall" to Control.Monad.Dep.Has

0.4.4.0

• added Control.Monad.Dep.Has, a generic "Has" typeclass which favors a style in which the components come wrapped in records or newtypes.

• added "useEnv" to Control.Monad.Dep.Class.

0.4.0.0

Actually no breaking changes here, but a change in the recommended structure of the HasX helper classes, and in how to write general code against those typeclasses.

• added Control.Monad.Dep.Class

0.1.3.0

• re-exported Control.Monad.Trans

0.1.2.0

• re-exported Control.Monad.Reader.Class

0.1.1.0

• Added NilEnv.

0.1.0.2

• Minor documentation changes.

0.1.0.1

• Minor documentation changes.

0.1.0.0 -- YYYY-mm-dd

• First version. Released on an unsuspecting world.
