Documentation

data SExpr Source

Constructors SAtom Atom SList [SExpr] Instances Eq SExpr Show SExpr Pretty SExpr Repr SExpr

data Atom Source

Constructors SFloat Double SInt Integer SSymbol String SString String SChar Char SBool Bool SFunction Function Instances Eq Atom Show Atom

type Indent = Int Source

type Exporter = Functions -> FilePath -> IO () Source

The type of a function to export (user) functions to a file.

data SchemeOptions Source

Constructors SchemeOptions defineWithLambda :: Bool use explicit lambda in function definitions, (define f (lambda (a b) ...) Instances Eq SchemeOptions Show SchemeOptions

defaultSchemeOptions :: SchemeOptions Source

exprToSExpr :: Expr -> SExpr Source

functionNameToSchemeName :: String -> String Source

valueToSExpr :: Value -> SExpr Source

exprToSchemeRepr :: Expr -> String Source

exprToSchemePretty :: Expr -> String Source

exprToScheme :: Expr -> String Source

inl :: Int -> String Source

Newline and indent

sepLines2 :: [String] -> String Source

sepLines2 is like sepLines, but adds an extra n between each pair of lines so they are double spaced.

functionsToSExprs :: SchemeOptions -> Functions -> [SExpr] Source

Convert Sifflet Functions to Scheme SExprs

functionsToPrettyScheme :: SchemeOptions -> Functions -> String Source

Convert Sifflet Functions to pretty Scheme

defToSExpr :: SchemeOptions -> FunctionDefTuple -> SExpr Source

Convert a FunctionDefTuple to a Scheme SExpr. Use the form (define (name . args) body) except when there are zero arguments, which becomes a Scheme constant rather than a function, use (define name expr).

exportScheme :: SchemeOptions -> Exporter Source

Export functions to a Scheme file.
