Build Status

A bare-bones proof of concept implementation of a typesafe printf-like interface where the format string is provided as a type-level string.

This library uses the 0.12 version of the compiler.

Example

format (SProxy :: SProxy "Hi %s! Your favourite number is %d") "Bill" 16

produces the string

"Hi Bill! Your favourite number is 16"

A function of the "right type" is generated from the format string, so that

:t format (SProxy :: SProxy "Hi %s! Your favourite number is %d")

gives

String -> Int -> String

TODO

Currently only "%d" and "%s" are supported, without any other fancy formatting.
