Scanf is the C-style of io-stream formatted reading.  
This version provides most features of standard scanf C function family.  
[Scanf.jl](https://github.com/KlausC/Scanf.jl)

example usage:

```julia
julia> using Scanf

julia> r, a, b, c, d = @scanf "42 -infABCDE hello" "%d%f%5c%s" 0 0f0 String ""
(4, 42, -Inf32, "ABCDE", "hello")

```

Discussions and improvement requests are welcome.

1. Documentation should copy relevant part of the C++ standard description?
2. argument specifications with `Ref` wrappers maybe not useful, remove?
