TODO

0.7.4 [2023.10.05]

  • Support building with scotty-0.20.

0.7.3

  • Allow building with GHC 9.0.

0.7.2

  • Render Unicode codepoints beyond 0xFFFF properly.

0.7.1

  • Remove the wiki-suite test suite from blank-canvas.cabal, as it was never intended to work as a traditional test suite. The functionality of wiki-suite has moved to a subdirectory of the upstream blank-canvas repository.

0.7

  • Strengthen the Monad constraint on readColourName to MonadFail.

0.6.3

  • Use base-compat-batteries.

0.6.2

Additions

  • Add Semigroup instance for Canvas

0.6.1

  • Fix building with aeson-1.2.2.0.

0.6

API changes

  • The (#) function had its type generalized from a -> (a -> Canvas b) -> Canvas b to a -> (a -> b) -> b. This allows it to be used with font length units.
  • Added more type synonyms (Interval, Degrees, Radians, etc.) to more clearly indicate what functions expect constrained values.
  • showbJS (formerly showJS) and jsStyle now return a text Builder instead of a String. This change was introduced as part of a larger blank-canvas refactoring to increase performance. See the Data.Text.Lazy.Builder module from the text package for more details on how to use Builders.

API additions

  • A new ADT for Fonts has been added in Graphics.Blank.Font that can be used in place of Text. For example, "30pt Calibri" is equivalent to (defFont "Calibri") { fontSize = 30 # pt }.
  • A generalized font function of type CanvasFont canvasFont => canvasFont -> Canvas () was added to Graphics.Blank.Font that can accept a Text or Font argument. The font function in Graphics.Blank remains of type Text -> Canvas ().
  • Added a cursor function to change the browser cursor. Also added the Graphics.Blank.Cursor module containing a generalized cursor function that uses a Cursor ADT instead of Text.
  • Added Bounded, Enum, Eq, Ix, Ord, and Show instances for more data types
  • Added support for more MIME types via the mime-types library

Additions

  • Allowed building with base-4.8.0.0

Other

  • Require scotty >= 0.10 and kansas-comet >= 0.4

0.5

API changes

  • Using Double rather than Float
  • Generalized saveRestore to be polymorphic

API additions

  • Added sync for forcing synchronization between the server and client
  • Added argument specific variants of drawImage and putImageData.
  • Added ADTs for RepeatDirection, Alignment, Baseline, LineEnds, Corner (previous used Text)
  • Use of the colour(sic) package (Text is still allowed)

Bug fixes:

  • Fixed unicode escapes in strings

Additions:

  • Allow Images to access client-side filesystem
