[![Build Status](https://travis-ci.org/sferik/twitter-crystal.svg?branch=master)][travis]

[travis]: https://travis-ci.org/sferik/twitter-crystal

## Installation

Add this to your application's `shard.yml`:

```yaml
dependencies:
  twitter-crystal:
    github: sferik/twitter-crystal
    version: ~> 0.2.1
```

In your terminal run:

```bash
$ crystal deps
```

This will get the latest code from this github repository and copy it to a `lib` directory. All that's left is to require it:

```crystal
require "twitter-crystal"
```

## Usage

After the installation, you can use twitter-crystal by creating a client object:

```crystal
require "twitter-crystal"

consumer_key        = "your consumer key"
consumer_secret     = "your consumer secret"
access_token        = "your access token"
access_token_secret = "your access token secret "

client = Twitter::REST::Client.new(consumer_key, consumer_secret, access_token, access_token_secret)
```

All the necessary keys can be generated by [creating a Twitter application](https://dev.twitter.com/oauth/overview/application-owner-access-tokens).

**Post/Delete a tweet**
```crystal
# post a tweet
client.update("Good morning")

# delete a tweet
client.destroy_status(897099923128172545)
```

**Follow a user(by screen name or user_id)**
```crystal
client.follow("kenta_s_dev")
client.follow(776284343173906432)
```

**Unfollow a user(by screen name or user_id)**
```crystal
client.unfollow("kenta_s_dev")
client.unfollow(776284343173906432)
```

**Search users**
```crystal
client.user_search("Crystal lang") # returns maximum of 20 users
```

**Fetch users by user_id/screen_name**
```crystal
client.users("kenta_s_dev")

# fetch multiple users(maximum is 100)
client.users("sferik", "yukihiro_matz", "dhh")
```

**Fetch followers' IDs**
```crystal
client.follower_ids
```

**Fetch followees' IDs**
```crystal
# In Twitter API documents, followees are called 'friends'.
client.friend_ids
```

**You can also call Twitter's API directly using the `get` or `post` method**
```crystal
client.get("/1.1/users/show.json", { "screen_name" => "sferik" })
client.post("/1.1/statuses/update.json", { "status" => "The world is your oyster." })
```

If you want to call the API directly, refer to the [API reference](https://dev.twitter.com/rest/reference).
