String.Format

String.Format exposes simple helpers for String interpolation to help you avoid difficult-to-read concatenation. Both named and unnamed placeholders are supported.

import String.Format


-- Bad
hello : String -> String
hello name =
    "Hello, " ++ name ++ "!"


-- Readable
hello : String -> String
hello name =
    "Hello, {{ }}!"
        |> String.Format.value name


-- More readable
hello : String -> String
hello name =
    "Hello, {{ name }}!"
        |> String.Format.namedValue "name" name
