## Quickstart

First, add Tentacat to your `mix.exs` dependencies:

```elixir
def deps do
  [{:tentacat, "~> 1.0"}]
end
```

Ensure that `tentacat` is added as an application in your `mix.exs`:

_(note: this is only necessary for Elixir < 1.3)_

```elixir
def application do
  [applications: [:tentacat]]
end
```

Fetching dependencies and running on elixir console:

```console
mix deps.get
iex -S mix
```

You will something like this:

```elixir
Erlang/OTP 17 [erts-6.0] [source] [64-bit] [smp:4:4] [async-threads:10] [hipe] [kernel-poll:false]

Interactive Elixir (0.13.3) - press Ctrl+C to exit (type h() ENTER for help)
iex(1)>
```

Now you can run the examples!

## Examples

Every call to GitHub needs a client, but if you want to use unauthenticated requests we will provide an unauthenticated client for you. Keep in mind that GitHub has different [rate-limits](https://developer.github.com/v3/#rate-limiting) if you authenticate or not.

Getting info from a user using a client

```elixir
iex> client = Tentacat.Client.new
%Tentacat.Client{auth: nil, endpoint: "https://api.github.com/"}
iex> Tentacat.Users.find client, "edgurgel"

```

Getting info from a user without a defined client

```elixir
iex> {200, data, _response} = Tentacat.Users.find("edgurgel")

iex(8)> get_in(data, ["name"])
"Eduardo Gurgel"
```

Getting info from the authenticated user

* Using user and password:

```elixir
iex> client = Tentacat.Client.new(%{user: "user", password: "password"})
%Tentacat.Client{auth: %{user: "user", password: "password"}, endpoint: "https://api.github.com/"}
iex> Tentacat.Users.me(client)
```

* Using a personal access token [Github personal API token](https://github.com/blog/1509-personal-api-tokens)

```elixir
iex> client = Tentacat.Client.new(%{access_token: "928392873982932"})
%Tentacat.Client{auth: %{access_token: "928392873982932"}, endpoint: "https://api.github.com/"}
iex> Tentacat.Users.me(client)
```

Accessing another endpoint

```elixir
iex> client = Tentacat.Client.new(%{access_token: "928392873982932"}, "https://ghe.example.com/api/v3/")
%Tentacat.Client{auth: %{access_token: "928392873982932"}, endpoint: "https://ghe.example.com/api/v3/"}
iex> Tentacat.Users.me(client)
```

## Misc

Having that Github Reviews API is still in a pre-release state
you need to set an additional header in your config.

```elixir
config :tentacat, :extra_headers, [{"Accept", "application/vnd.github.black-cat-preview+json"}]
```

### Deserialization Options

You can pass deserialization options to the library used to decode JSON
using:

```elixir
# To have Atom keys
config :tentacat, :deserialization_options, [labels: :atoms]
```

See: https://github.com/talentdeficit/exjsx#decodejson-opts for available options.

## Contributing

Start by forking this repo

Then run this command to fetch dependencies and run tests:

```console
MIX_ENV=test mix do deps.get, test
```

If you are using Intellij and debugging the test suite - be sure to set 'INTELLIJ_ELIXIR_DEBUG_BLACKLIST=hackney' in the Elixir Mix Eunit configuration - if you fail to do so the mocked hackney module will be reloaded from disk and tests will behave abnormally.
