README
ExPrintf 
A printf / sprintf library for Elixir. It works as a wrapper for :io.format.
When learning Elixir / Erlang, remembering :io.format style is a little tough. This one can be used as syntax sugar, or an util to convert printf format to Elixir (Erlang) one.
Examples
Basic Usage
defmodule Sample do
import ExPrintf
def test do
printf("number = %d\n", [10])
# -> number = 10
IO.puts sprintf("string = %s", ["abc"])
# -> string = abc
format = parse_printf("format = %d %.2f\n")
IO.inspect format
# -> "format = ~w ~.2f\n"
:io.format(format, [10, 10.153])
# -> format = 10 10.15
IO.puts :io_lib.format(format, [10, 10.153])
# -> format = 10 10.15
end
end
Sample.test
Sample Execution
$ mix run sample.ex
number = 10
string = abc
"format = ~w ~.2f\n"
format = 10 10.15
iex
$ git clone [email protected]:parroty/exprintf.git
$ cd exprintf
$ ./run_iex.sh
$ iex(1) -> parse_printf("%d")

Dynamo
The following hosts a sample dynamo application for the printf format conversion.

TODO
- Improve error checking
- Improve format support coverage
- sprintf("%05d", [-10]) results in "00-10", instead of "-00010".
