You probably should be using a database that supports `utf8mb4` though (and not this gem), like PostgreSQL or MySQL (5.5+). We built this gem because stock [Heroku](http://heroku.com) machines cannot compile the `mysql2` gem to use the `utf8mb4` encoding (because they ship with an old version of `libmysqlclient`).

---

## Deprecation notice

:warning: This repository is now deprecated since most MySQL and PostgreSQL
installations these days support storing _native_ emoji characters. The gem
will continue to work as expected but `v0.3` will be the last version.

## Installation

Add this line to your application's Gemfile:

```ruby
gem 'emojimmy'
```

### Usage

#### ActiveRecord

You have to edit your models to specify which fields will be storing emoji characters:

```ruby
# app/models/comment.rb
class Comment < ActiveRecord::Base
 stores_emoji_characters :body
end
```

Your model will now be able to store emoji characters in its `body` column.

```ruby
# Create a comment with an emoji
@comment = Comment.create(body: "Hello! 😁")

# Our comment has been saved in the database
@comment.persisted? # => true

# Magic! Our body contains the emoji!
@comment.body # => "Hello! 😁"

# The real magic… how emoji are actually stored
@comment.read_attribute(:body) # => "Hello! :grin:"
```

#### Custom

If you only want to use Emojimmy’s conversion methods, you can use two methods, `token_to_emoji` and `emoji_to_token`:

```ruby
Emojimmy.emoji_to_token("Hello! 😁")
# => "Hello! :grin:"

Emojimmy.token_to_emoji("Hello! :grin:")
# => "Hello! 😁"
```
