Text.Reprinter.StringLike

Documentation

class (Monoid a, IsString a) => StringLike a where

Data types that can be used as a list-like structure of Chars.

Clumsy solution to allow parameterising over the input type (Text, ByteString, String), rather than converting to and from an internal concrete type. Only operations required by the reprinting algorithm are included. Where possible, operations are prefilled using presumed-existing instances (any [Char]-like should be a monoid and have a String -> a).

Class for string-like datastructures; used by the overloaded string extension (-XOverloadedStrings in GHC).
