eval :: Expr -> IO (Maybe String) Source

Evaluate an Expr; this is where the magic happens! If successful, returns Just a String, which you can do what you like with.

mkCmd :: Expr -> (String, [String]) Source

mkGhcPkg :: [Pkg] -> [Char] Source

mkHs :: Expr -> String Source

trim :: String -> String Source

raw :: String -> Expr Source

A raw String of Haskell code, with no packages or modules. You can use OverloadedStrings to call this automatically.

($$) :: Expr -> Expr -> Expr Source

Apply the first Expr to the second, eg. `f $$ x` ==> `f x`

asString :: Show a => a -> Expr Source

Convert the argument to a String, then send to raw

qualified :: Mod -> String -> Expr Source

withMods :: [Mod] -> Expr -> Expr Source

withPkgs :: [Pkg] -> Expr -> Expr Source
