Undefined function defparsec/1

[daviwesley]

I created a project using the mix new project and add the dependency in mix.exs, I found this example in documentation

defmodule MyParser do
  import NimbleParsec

  defparsec integer(min: 1) |> tag(:integer)
end
MyParser.integer("1234")

when I run this example from project directory using the iex -S mix I got this error message
** (CompileError) iex:12: undefined function defparsec/1

Elixir 1.9.1
NimbleParser 0.5.1

there's no defparsec/1 but there's defparsec/2,3; you need to give a name to your parsec:

defparsec :my_int, integer(min: 1) |> tag(:integer)

Oh, the documentation is wrong indeed in a couple places, I'll fix it up. Thanks for the report!
