tree-diff

Diffing of (expression) trees.

Examples

As a bonus, multiline Strings and Text are diffed linewise:

Changes

0.1

  • Support GHC-7.4 … 8.8 (use allow-newer for GHC-8.8-alpha).
  • Use raw GHC.Generics (drop generics-sop dependency)
  • Use own memoising (Vector lookup, drop MemoTrie dependency)
  • Singleton data-types (both data and newtypes) are printed in App form (i.e. no-record).
  • Change license to GPL-2.0-or-later

0.0.2.1

  • Support semigroups-0.19, hashable-1.3 and generics-sop-0.5

0.0.2

  • Print compact diffs
  • Add ToExpr instance for ShortByteString

0.0.1

  • Use BS.readFile and BS.writeFile in ediffGolden. This makes files read and written in UTF8 independently of locale. Fixes builds on appveyor.

0.0.0.1

  • Move to build-type: Simple

0

  • First version. Released on an unsuspecting world.
