Sharing params

[mmcc]

We have quite a few query parameters that are shared across many routes, so it makes a lot of sense for us to share as much as we can there. I've tried a few different routes, but my metaprogramming-fu does not seem to be up to the challenge. Is this possible or am I just doing it wrong?

Here's what I've attempted so far:

# Shared parameters
def shared_list_params do
  quote do
    parameter :timeframe, :array, [description: "Timeframe array or duration string.", example: "24:hours"]
    parameter :page, :number, [optional: true, default: 1, example: 1]
    parameter :order_by, :string, [description: "Value to order the results by", default: "negative_impact"]
    parameter :order_direction, :string, [members: ["asc", "desc"]]
    parameter :limit, :number, [default: 100]
  end
end

api :GET, "/v1/something" do
  title "List somethings"
  description "Returns a whole lot of something"

  # Attempt 1
  unquote(shared_list_params())

  # Attempt 2
  Code.eval_quoted(shared_list_params())
end

Neither of these blew up, but they didn't work, either. Any ideas on how to achieve something like this while using the api macro?

I did some experimenting and found a way to do it, but not without changing the original api/2 macro. Please have a look at PR #24 and let me know what you think.
