Changelog

The library uses semantic versions to identify stable releases.

Release 4.6.x

Features

  • #68: Implements generic representations
  • Support product lenses for records (lens:p/1).

Release 4.5.x

Features

  • #54: Implements pattern matching within do-notation
  • Add typecast utility for scalar types.
  • Support MFA generator for streams
  • implements lens isomorphism (lens:iso/2, lens:iso/4) and product lens (lens:p/1).

Improvements

  • Support lists comprehension at do-notation

Release 4.4.0

Features

  • Implements basic lenses: identity (lens:id/0), constant (lens:const/1)
  • Implements binary lenses: head of binary (lens:hbits/1), tail of binary (lens:tbits/), bit focus (lens:bits/2)

Release 4.3.2

Features

  • #30 Define a conditional fail (require) that conditionally lifts a value either to object or error of category
  • #29 Support category transformers as part of nested expressions
  • Define a generic operators to modify monad context or execute side-effect

Improvements

  • Fix various of compilation errors of function compositions
  • Improve test coverage of parse transforms
  • Support list comprehensions and list operators as part of function composition
  • Export datum:lens() data type

Release 4.3.0

Features

  • #20 New category undefined
  • #25 Product lens combinator lens:p(...) to spawn multiple fields into abstract view
  • #19 Macros to pattern match empty data structures (see datum.hrl)
  • #22 Define new lens lens:require/1, lens:defined/0 to support development of unit testing (validate nested structures using lenses)

Improvements

  • Improve interface semantic, introduce lens:map/3 function instead of lens:apply/3
  • Re-implement lens isomorphism feature using product lens
  • Update documentations and add examples about lenses
  • Use option data type to warp lens output
