1.7.1

• Deprecate the Data.Text.Prettyprint.* modules
  • Users should migrate to the new Prettyprinter module hierarchy.
  • The old modules will be removed no sooner than September 2022.
• Make text an optional dependency:
  • When built with -f-text, any text-based APIs will operate on Strings instead.
• Documentation improvements:
  • #194
  • 1f0bffe

1.7.0

Breaking changes

• Fix layoutPretty and layoutSmart so they don't produce trailing whitespace as a result of indenting empty lines.
  • Users of removeTrailingWhitespace should check whether it is still needed.
• Use floor instead of round to compute ribbon width.
• Remove deprecated Data.Text.Prettyprint.Doc.Render.ShowS module.
• Add optimized implementation of stimes for Doc.
• Generalize the type of layoutCompact to clarify that it doesn't preserve annotations.
• Add strictness annotations in SimpleDocStream and PageWidth.

Non-breaking changes

• Add shallower Prettyprinter module hierarchy exposing the same API.
  • The current plan for the existing Data.Text.Prettyprint.Doc* modules is:
    • Start deprecation in early 2021.
    • Remove the modules after a deprecation period of at least one year.
• Fix build with GHC 7.4.
• Various documentation improvements.

1.6.2

• Speed up rendering to lazy and strict Text.
• Documentation improvements for group and flatAlt.
• Internal refactoring of the layoutWadlerLeijen-based layouters.

1.6.1

• Slightly reduce the scope of the fitting predicates for some edge cases.
• Use an export list in Data.Text.Prettyprint.Doc.Internal.
• Improve group for Union and FlatAlt.
• Speed up removeTrailingWhitespace.
• Improve generating spaces for indentation and spaces.
• Simplify some Doc constants by defining them as Doc literals.
• Enable -O2.
• Various documentation fixes and improvements.

1.6.0

Breaking changes

• Fix fuse's handling of annotated documents:
  • Don't remove annotations on empty documents.
  • Apply fusion within annotations.
• Fix layouting of hard linebreaks with Unbounded page widths.

Non-breaking changes

• Speed up group for documents containing linebreaks and previously grouped documents.
• Add debugging helpers in Data.Text.Prettyprint.Doc.Internal.Debug
• Documentation improvements and fixes

1.5.1

• Removing trailing whitespace sometimes restored necessary whitespace in the wrong spot

1.5

• Fix inconsistent formatting within align and wide sub-docs on narrow layouts

1.4

• Add fixity declaration to <+>, matching <>
• Fix removal of trailing whitespace

1.3.0.1

• Support Stack 2

1.3.0

• Add alignment to Pretty [a] instance
• Fix removal of blank lines in removeTrailingWhitespace
• Widened support for GHC versions 7.4–8.8

1.2.1.1

• Fix dependency of doctest suite

1.2.1

• Add function to trim trailing space in layouted SimpleDocStream, removeTrailingWhitespace
• Add Pretty instances for Identity and Const

1.2.0.1

• Fix alterAnnotationsS (and thus unAnnotateS), which removed pushing, but not popping, style frames. This led to them throwing errors in pretty much all use cases.

1.2

• encloseSep does no longer include an align wrapper; in other words,

  encloseSep_old … = align (encloseSep_new …)
  

• Change the default ribbon fraction to 1 (was 0.4)

• Expose viaShow and unsafeViaShow from the public module

• Fix layoutSmart behaving as if there was no space left for unbounded pages

1.1.1

• Add panicPeekedEmpty and panicPoppedEmpty to the panic module

1.1.0.1

• Rendering directly to a handle is now more efficient in the Text renderer, since no intermediate Text is generated anymore.
• Remove upper version bounds from .cabal files

1.1

• Allow alterAnnotations to convert one annotation to multiple ones, to support e.g. Keyword ---> Green+Bold
• Remove Pretty instance for Doc: the implicit un-annotation done by it did more harm than good.

1.0.1

• Add alterAnnotations, which allows changing or removing annotations. reAnnotate and unAnnotate are now special cases of this.
• Fix »group« potentially taking exponential time, by making the (internal) flatten function detect whether it is going to have any effect inside group.
• Add proper version bounds for all dependencies and backport them to version 1
• Haddock: example for Pretty Void

1

• Add Foldable/Traversable instances for SimpleDocTree, SimpleDocStream
• Add Functor instances for Doc, SimpleDocTree, SimpleDocStream
• Add the simplified renderers renderSimplyDecorated and renderSimplyDecoratedA to the tree and stack renderer modules
• Lots of typo fixes and doc tweaks
• Add a changelog :-)
