Framer

A few helper classes to resize iodata streams and iolists.

If you do not want to add another dependency, feel free to steal any of the functions. They aren't long.

The two main functions are:

• resize_stream/2 for resizing elements of an iodata stream
• resize/2 for resizing elements of an iodata list

Examples

Resizing a iodata stream:

  iex> stream = ["The brown", " fox", ["that ", "jumped"], " up."]
  iex> Framer.resize_stream(stream, 5) |> Enum.to_list()
  [["The b"], ["rown", " "], ["fox", "th"], ["at ", "ju"], ["mped", " "], ["up."]]

Resizing an iolist:

  iex> enum = ["Hello ", "World"]
  iex> Framer.resize(enum, 4)
  [["Hell"], ["o ", "Wo"], ["rld"]]

Installation

If available in Hex, the package can be installed by adding framer to your list of dependencies in mix.exs:

def deps do
  [
    {:framer, "~> 0.1.0"}
  ]
end

Caution

I have not benchmarked any of those functions, nor tested heavily in a production environment. Please proceed with caution.
