Repository: afcondon/purescript-hylograph-selection

Core Expression DSL

Finally tagless encoding for attribute expressions. Enables multiple interpreters: Eval (D3), CodeGen, SVG, English, etc.

#NumExpr Source

class NumExpr :: (Type -> Type) -> Constraintclass NumExpr repr  where

Numeric expressions

Members

lit :: Number -> repr Number
add :: repr Number -> repr Number -> repr Number
sub :: repr Number -> repr Number -> repr Number
mul :: repr Number -> repr Number -> repr Number
div :: repr Number -> repr Number -> repr Number
negate :: repr Number -> repr Number

#StringExpr Source

class StringExpr :: (Type -> Type) -> Constraintclass StringExpr repr  where

String expressions

Members

str :: String -> repr String
concat :: repr String -> repr String -> repr String

#BoolExpr Source

class BoolExpr :: (Type -> Type) -> Constraintclass BoolExpr repr  where

Boolean expressions

Members

bool :: Boolean -> repr Boolean
and :: repr Boolean -> repr Boolean -> repr Boolean
or :: repr Boolean -> repr Boolean -> repr Boolean
not :: repr Boolean -> repr Boolean
ifThenElse :: forall a. repr Boolean -> repr a -> repr a -> repr a

#CompareExpr Source

class CompareExpr :: (Type -> Type) -> Constraintclass CompareExpr repr  where

Comparison expressions (produce Boolean from Numbers)

Members

lt :: repr Number -> repr Number -> repr Boolean
lte :: repr Number -> repr Number -> repr Boolean
gt :: repr Number -> repr Number -> repr Boolean
gte :: repr Number -> repr Number -> repr Boolean
eq :: repr Number -> repr Number -> repr Boolean

#StringCompareExpr Source

class StringCompareExpr :: (Type -> Type) -> Constraintclass StringCompareExpr repr  where

String comparison expressions Separate from CompareExpr to keep numeric and string comparisons distinct

Members

strEq :: repr String -> repr String -> repr Boolean
strNeq :: repr String -> repr String -> repr Boolean

#TrigExpr Source

class TrigExpr :: (Type -> Type) -> Constraintclass TrigExpr repr  where

Trigonometric expressions Essential for polar/radial visualizations (chord diagrams, radial trees, etc.)

Members

sin :: repr Number -> repr Number
cos :: repr Number -> repr Number
tan :: repr Number -> repr Number
asin :: repr Number -> repr Number
acos :: repr Number -> repr Number
atan :: repr Number -> repr Number
atan2 :: repr Number -> repr Number -> repr Number
pi :: repr Number
