Things i think need improvement

• Diagrams
• GHC error messages
• Haskell Cookbook
• Haskell explained to the busy
• Mac OS X

Chlor

• Haskell SVN
• C SVN

Todo

• data Shape = Circle | Ellipse | Path | Rectangle | RegularPolygon | Text
  • area :: Shape -> Area
    • returns the shape area, without stroke
  • path :: Shape -> Path

• class ObjectLike
  • area :: a -> Area
    • returns the boundig area, including stroke and effects
  • effects:: a -> [Effect]
  • fill:: a -> maybe paint
  • shapes :: a -> [Shape]
    • converts the Object to a list of Shape
  • stroke:: a -> Maybe Stroke

• Layout
  • size
    • adjustToArea :: Object -> Area -> Object
    • adjustToHeight :: Object -> Double -> Object
    • adjustToWidth :: Object -> Double -> Object
    • getArea :: Object -> Area
  • Instances
    • Column
    • Grid (cols, rows, margins)
    • Margin/Frame
      • content size (absolute, relative, remaining)
      • margin sizes (absolute, relative, remaining)
    • Row

• Export
  • Svg

• Vector
  • createVectors :: [Double] -> [Vector2d]

• AffineTransformation

• Shape
  • Sine
  • Spiral
  • Star
  • Pie Chart (only for displaying fractions)

• Path

Simplified Haskell homepage

A simplified Haskell frontpage

Why?

• to add a structure
• to reduce redundancy
• to make scanning easier:
  • why scanning
  • first two words
