Changelog for polysemy
1.2.0.0 (TODO)
Breaking Changes
- All
lower-
interpreters have been deprecated, in favor of corresponding-Final
interpreters. runFixpoint
andrunFixpointM
have been deprecated in favor offixpointToFinal
.- The semantics for
runNonDet
when<|>
is used inside a higher-order action of another effect has been changed. - Type variables for certain internal functions and
failToEmbed
have been rearranged.
Other changes
- Added
Final
effect, an effect for embedding higher-order actions in the final monad of the effect stack. Any interpreter should use this instead of requiring to be provided an explicit lowering function to the final monad. - Added
Strategy
environment for use together withFinal
- Added
asyncToIOFinal
, a better alternative oflowerAsync
- Added
errorToIOFinal
, a better alternative oflowerError
- Added
fixpointToFinal

will now complain ifDataKinds
isn't enabled (thanks to @pepegar)

0.5.0.0 (2019-06-26)
Breaking Changes
- Removed the internal
Effect
machinery
New Effects and Interpretations
- New effect;
Async
, for describing asynchronous computations - New interpretation for
Resource
:runResourceBase
, which can lowerResource
effects without giving a lowering natural transformation - New interpretation for
Trace
:runTraceAsList
- New combinator:
withLowerToIO
, which is capable of transformingIO
-invariant functions as effects.
Other Changes
- Lots of hard work on the package and CI infrastructure to make it green on GHC 8.4.4 (thanks to @jkachmar)
- Changed the order of the types for
runMonadicInput
to be more helpful (thanks to @tempname11) - Improved the error machinery to be more selective about when it runs
