Helpers to convert common types into a String
.
fromBool : Basics.Bool -> String
Convert a Bool to a String matching its constructor.
fromWeekday : Time.Weekday -> String
Convert a Time.Weekday to a String matching its constructor.
fromDict : (comparable -> String) -> (v -> String) -> Dict comparable v -> String
Convert a Dict to a String using nested conversions.
import Dict
fromDict String.fromInt String.fromFloat (Dict.fromList [(1, 1.5)])
--> "Dict.fromList [(1,1.5)]"
fromHttpError : Http.Error -> String
Convert an Http.Error to a String.
fromHttpResponse : Http.Response String -> String
Convert an Http.Response String to a String.
fromList : (a -> String) -> List a -> String
Convert a List to a string using a nested conversion.
fromList String.fromInt [1, 2, 3]
--> "[1,2,3]"
fromMaybe : (a -> String) -> Maybe a -> String
Convert a Maybe to a String using a nested conversion.
fromMaybe String.fromInt (Just 1)
--> "Just 1"
fromMonth : Time.Month -> String
Convert a Time.Month to a String matching its constructor.
fromRecord : List ( String, a -> String ) -> a -> String
Build a record string for debugging and logging with pairs of keys and string conversion functions, meant to be paired with accessors
fromRecord [ ("hello", .hello >> String.fromInt ) ] { hello = 1 }
--> "{ hello = 1 }"
fromSet : (comparable -> String) -> Set comparable -> String
Convert a Set to a string using a nested conversion.
import Set
fromSet String.fromInt (Set.fromList [1, 2])
--> "Set.fromList [1,2]"
fromString : String -> String
Convert a String to a debugging version of that String.
fromString "hello \"world\""
--> "\"hello \\\"world\\\"\""
fromTuple2 : (a -> String) -> (b -> String) -> ( a, b ) -> String
Convert a 2-tuple to a string using nested conversions.
fromTuple2 String.fromInt String.fromFloat ( 1, 1.5 )
--> "(1,1.5)"
fromTuple3 : (a -> String) -> (b -> String) -> (c -> String) -> ( a, b, c ) -> String
Convert a 3-tuple to a string using nested conversions.
fromTuple3 String.fromInt String.fromFloat String.fromInt ( 1, 1.5, 2 )
--> "(1,1.5,2)"
fromValue : Json.Encode.Value -> String
Convert a Json.Decode.Value to a JSON String.
withUnionConstructor : String -> List String -> String
Nest some arguments under a tag, including parentheses when needed. Helpful for printing union type values.
withUnionConstructor "Ok" [ String.fromInt 1 ]
--> "Ok 1"
