Changelog for typed-encoding

Anticipated future breaking changes

• Data.TypedEncoding.Internal.Class.IsStringR expected to be be changed / replaced
• (post 0.3) "enc-B64" will be moved to a different package (more distant goal)

0.3.0.1

• Documentation changes / corrections
• New doctest tests
• Haddock coverage and @since flags

0.3

• Breaking: Numerous changes on the implementation side, new version should be largely compatible on the call site except for small differences in constraints and order for type variables (if -XTypeApplications is used). See v3 migration guide.

  • EncodeFAll, DecodeFAll, RecreateFAll, EncodeF, DecodeF, RecreateF replaced with EncodeAll, DecodeAll, ValidateAll, Encode, Decode, Validate.
  • functions used to create encoding instances or encoding combinators (e.g. implEncodeP) are now more precisely typed
  • Displ String instance (used in examples, has been made consistent with Text and ByteString)
  • Modules under Data.TypedEncoding.Combinators merged into Data.TypedEncoding.Instances.
  • Modules under Data.TypedEncoding.Internal have been reorganized and moved outside of Internal. Various changes that make the library easier to navigate. for better navigation and discovery.
  • some previously exported combinators (e.g. implTranF) have moved to Data.TypedEncoding.Instances.Support.Unsafe
  • ToEncString, FromEncString have more type variables and function name but backward compatible functions have been provided.
  • Superset typeclass removed, replaced with IsSuperset type family.
  • Minor changes in forall variable order in combinators for "r-bool:" encodings.
  • Encoder type removed, replaced by Encodings.
  • checkWithValidationsEnc combinator renamed to check
  • (Considered private) MkCheckedEnc constructor became UnsafeMkCheckedEnc
  • (Considered private) MkEnc constructor became UnsafeMkEnc

• new functionality

  • new types and typeclasses are based on both encoding name and algorithm name allowing typeclass definitions for open encodings like "r-ban:" that can contain arbitrary symbol literals.
  • new set of combinators grouped into _ (compiler decided algorithm), ' (program specifies algorithm), and algorithm name ~ encoding name categories
  • above combinator subsumes partial encoding / decoding combinators
  • EncodingSuperset class added

0.2.2

• Next version (0.3) will have number of breaking changes, some rethinking and a lot of cleanup, this version preps for some of that (see section above)
• Fixes
  • Conversions type safety issues
  • new and corrected approach to conversions (all old conversion functions have been deprecated)
  • corrected documentation in Data.TypedEncoding.Combinators.Restriction.BoundedAlphaNums
• new functionality:
  • Enc versions for pack/ unpack for Text and ByteString.
  • Enc versions of decodeUtf8 / encodeUtf8
  • new and corrected approach to conversions (all old conversion functions have been deprecated)
  • IsSuperset type family with basic combinators deprecates Superset typeclass.
  • more modules exported from Data.TypedEncoding.Instances.Support for instance and combinator creation
  • more utility type families Data.TypedEncoding.Internal.Util.TypeLits
  • more utility combinators for creating encoding instances and combinators.
  • String instance added in number of places, including for "r-ASCII" encoding
  • few more support convenience functions.
• deprecation warnings (see above)

0.2.1.0

• new functionality:
  • bounded alpha-numeric restriction encodings (r-ban)
  • boolean algebra of encodings
• minor improvements
  • dropped IsString constraint from instances in Data.TypedEncoding.Instances.Restriction.Common
  • added forall annotation to encodeAll and decodeAll

0.2.0.0

• breaking:
  • Data.TypedEncoding.Instances modules reorganized
  • Data.TypedEncoding.Internal.Class modules reorganized
  • Data.TypedEncoding.Internal.Utils module renamed
  • Several TypeAnnotations friendly changes:
    • Removed polymorphic kinds in most places
    • Changed typeclass name from Subset to Superset
    • flipped type parameters on FlattenAs, HasA typeclass functions
    • Removed Proxy parameters from several methods (few methods have a '_' backward compatible version which still has them)
• new functionality:
  • ToEncString - class allowing to convert types to Enc encoded strings
  • FromEncString - class reverses ToEncString
  • CheckedEnc untyped version of Enc containing valid encoding
  • SomeEnc existentially quantified version of Enc
  • UncheckedEnc for working with not validated encoding
  • RecreateExUnkStep constructor added to RecreateEx
  • utility IsStringR - reverse to IsString class
  • utility SymbolList class
• docs:
  • ToEncString example

0.1.0.0

• initial release
