ExPrintf Build Status

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

  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 git@github.com:parroty/exprintf.git

$ cd exprintf

$ ./run_iex.sh

$ iex(1) -> parse_printf("%d")

"~w"
