# Inky

[![Gem Version](https://badge.fury.io/rb/inky-rb.svg)](https://badge.fury.io/rb/inky-rb)

Inky is an HTML-based templating language that converts simple HTML into complex, responsive email-ready HTML. Designed for [Foundation for Emails](http://foundation.zurb.com/emails), a responsive email framework from [ZURB](http://zurb.com).

To include only the Foundation for Emails styles in your Asset Pipeline, without Inky, use the [**foundation_emails**](https://github.com/zurb/foundation-emails/#using-the-ruby-gem) gem.

Give Inky simple HTML like this:

```html
<row>
  <columns large="6"></columns>
  <columns large="6"></columns>
</row>
```

And get complicated, but battle-tested, email-ready HTML like this:

```html
<table class="row">
  <tbody>
    <tr>
      <th class="small-12 large-6 columns first">
        <table>
          <tr>
            <th class="expander"></th>
          </tr>
        </table>
      </th>
      <th class="small-12 large-6 columns first">
        <table>
          <tr>
            <th class="expander"></th>
          </tr>
        </table>
      </th>
    </tr>
  </tbody>
</table>
```

## Getting Started

Add the following gems to your Gemfile:

```ruby
gem 'inky-rb', require: 'inky'
# Stylesheet inlining for email **
gem 'premailer-rails'
```

Then execute:

```bash
bundle install
```

Run the following command to set up the required styles and mailer layout:

```bash
rails g inky:install
```

(You can specify the generated mailer layout filename like so: `rails g inky:install some_name`)

Rename your email templates to use the `.inky` file extension. Note that you'll still be able to use ERB within the `.inky` templates:

```
welcome.html      => welcome.html.inky
pw_reset.html.erb => pw_reset.html.inky
```

You're all set!

** The majority of email clients ignore linked stylesheets. By using a CSS inliner like `premailer-rails` or `roadie`, you're able to leave your stylesheets in a separate file, keeping your markup lean.

## Custom Elements

Inky simplifies the process of creating HTML emails by expanding out simple tags like `<row>` and `<column>` into full table syntax. The names of the tags can be changed with the `components` setting.

Here are the names of the defaults:

```ruby
{
  button: 'button',
  row: 'row',
  columns: 'columns',
  container: 'container',
  inky: 'inky',
  block_grid: 'block-grid',
  menu: 'menu',
  center: 'center',
  callout: 'callout',
  spacer: 'spacer',
  wrapper: 'wrapper',
  menu_item: 'item'
}
```
