args :: Args Source #

Default arguments to Speculate

constant :: Typeable a => String -> a -> Expr Source #

showConstant :: (Typeable a, Show a) => a -> Expr Source #

foreground :: Expr Source #

A special Expr value. When provided on the constants list, makes all the following constants foreground constants.

background :: Expr Source #

A special Expr value. When provided on the constants list, makes all the following constants background constants. Background constants can appear in laws about other constants, but not by themselves.

getArgs :: Args -> IO Args Source #

computeMaxSemiSize :: Args -> Int Source #

computeMaxCondSize :: Args -> Int Source #

computeInstances :: Args -> Instances Source #

types :: Args -> [TypeRep] Source #

atoms :: Args -> [[Expr]] Source #

keepExpr :: Args -> Expr -> Bool Source #

timeout :: Args -> Bool -> Bool Source #

shouldShowEquation :: Args -> (Expr, Expr) -> Bool Source #

shouldShowConditionalEquation :: Args -> (Expr, Expr, Expr) -> Bool Source #

reallyShowConditions :: Args -> Bool Source #

foregroundConstants :: Args -> [Expr] Source #

backgroundConstants :: Args -> [Expr] Source #

about :: Expr -> [Expr] -> Bool Source #

allAbout :: Expr -> [Expr] -> Bool Source #

Are all constants in an expression about a list of constants? Examples in pseudo-Haskell:

x + y `allAbout` [(+)] == True
x + y == z `allAbout` [(+)] == False
x + y == z `allAbout` [(+),(==)] == True
