Reap

Reap is a simple Elixir library for working with the refheap API. It uses the excellent hackney HTTP client and JSEX JSON encoder/decoder.

Usage

Reap only has one function you should care about: request/2, request/3. Here's some examples:

iex(1)> Reap.start
:ok
iex(2)> Reap.request(:post, "/paste", [contents: "foo"])
{:ok,
 [{"lines", 1}, {"date", "2013-08-01T04:42:44.155Z"}, {"paste-id", "17091"},
  {"fork", nil}, {"random-id", "6249eaf9c9c8186230243bb46"},
  {"language", "Plain Text"}, {"private", false}, {"views", 0},
  {"url", "https://www.refheap.com/17091"}, {"user", nil}, {"contents", "foo"}]}
iex(3)> Reap.request(:get, "/paste/17091")
{:ok,
 [{"lines", 1}, {"date", "2013-08-01T04:42:44.155Z"}, {"paste-id", "17091"},
  {"fork", nil}, {"random-id", "6249eaf9c9c8186230243bb46"},
  {"language", "Plain Text"}, {"private", false}, {"views", 0},
  {"url", "https://www.refheap.com/17091"}, {"user", nil}, {"contents", "foo"}]}

As you can see, if the request and json decode is successful we get back {:ok, body}. Let's see what happens if things go wrong:

iex(11)> Reap.request(:post, "/paste")
{:error, :refheap, [{"error", "Your paste cannot be empty."}]}

In this case, something went wrong on refheap and it gave us back an error. The second element of the tuple is the type of the error, and it can be :refheap if something bad happens on refheap, :json if JSON parsing of the body fails for some reason, or :http if we fail to make an http request at all. In the latter two cases, the entire hackney response gets returned as the third element of the tuple.
