ExTwitter

Twitter client library for elixir. It uses <a href="https://github.com/tim/erlang-oauth/" target="_blank">erlang-oauth</a> to call Twitter's REST API.

It only supports very limited set of functions yet. Refer to <a href="https://github.com/parroty/extwitter/blob/master/lib/extwitter.ex" target="_blank">lib/extwitter.ex</a> and <a href="https://github.com/parroty/extwitter/blob/master/test/extwitter_test.exs" target="_blank">test/extwitter_test.exs</a> for available functions and examples.

Usage

Use ExTwitter.configure to setup Twitter's OAuth authentication paramters. Refer to https://dev.twitter.com/docs for the detail.
Call functions in ExTwitter module (ex. ExTwitter.search("test")).
