Changes

1.7.1.1

  • Support ansi-wl-pprint-0.6.8

1.7.1

  • Support doctest-0.12

1.7

  • Make trifecta forward -Wcompatible: Adding Semigroup instances to correspond to every existing Monoid instance. This requires adding a Semigroup constraint to the Monoid instance for Parser to emulate the Semigroup-Monoid superclass relation that will be present in future versions of GHC. Adding a MonadFail instance for Parser
  • Revamp Setup.hs to use cabal-doctest. This makes it build with Cabal-2.0, and makes the doctests work with cabal new-build and sandboxes.

1.6.2.1

  • Add this changelog to the extra-souce-files in trifecta.cabal so that the changelog will appear on Hackage

1.6.2

  • Enable support for blaze-html-0.9 and blaze-markup-0.8

1.6.1

  • Remove redundant constraints from DeltaParsing's class methods. This is required for trifecta to build on GHC 8.0.2.

1.6

  • Version bumps to support GHC 8
  • Add line/col numbers to parse results by giving a list of all deltas when errors happen.

1.5.2

  • lens 4.13 support

  • Builds clean on GHC 7.10.

1.5.1.3

  • Support newer utf8-string versions and GHC 7.10

1.5.1.2

  • Work around lack of the old preEscapedString export in near-current blaze-markup.

1.5.1.1

  • Work around new exports in blaze.

1.5.1

  • Parsers 0.12.1 support. This removes many Show constraints introduced after 1.4

1.5

  • Properly PVP compliant point release for the parsers changes to properly handle notFollowedBy

1.4.3

  • Accidentally non-PVP compliant point release.

1.4.1

  • GHC 7.8.1 compatibility
