## Rails meta tags helpers

Seo and future-proof meta-tags for Rails, with good customizable defaults that also provide support for open-graph and csrf: all your meta tags in a single call.

### Install

``` rb
gem 'meta-tags-helpers'
```

### Examples

``` erb
<%= meta_tags(
    :title => "MyBlog - This is a Blog",
    :description => "The blog of mine & a reserved character",
    :og => {:type => "website"}
    :ns => {
      :my_custom_meta => "a value"
    }
    ) 
%>
```

or using defaults with setters (see below) just:

``` erb
<%= meta_tags %>
```

### What it generates? 

The first example above will produce the following html:

``` html
<meta name="charset" content="utf-8" />
<meta name="X-UA-Compatible" content="IE=edge,chrome=1" />
<meta name="viewport" content="width=device-width" />
<title>MyBlog - This is a Blog</title>
<meta property="description" content="The blog of mine &amp; a reserved character" />
<meta property="og:url" content="(THE CURRENT REQUESTED URL)" />
<meta property="og:type" content="website" />
<meta property="og:title" content="MyBlog - This is a Blog" />
<meta property="og:description" content="The blog of mine &amp; a reserved character" />
<meta property="ns:my_custom_meta" content="a value" />
<meta name="csrf-param" content="..." />
<meta name="csrf-token" content="..." />

```

**NOTE:** namespaced meta (eg. `og:title`) are supposed to be RDF properties and so they are marked using a `property` attribute.

### Setting meta tags from controller/partials/other views

You can customize some of defautls (see below) through handy helpers within controllers or views:

``` rb
meta_title(value = nil)
meta_description(value = nil)
meta_image(value = nil)
meta_type(value = nil)

```

### Defaults

This is the default options hash:

``` rb
default = {
  :charset => "utf-8", 
  :"X-UA-Compatible" => "IE=edge,chrome=1", 
  :viewport => "width=device-width",
  :title => meta_title,
  :description => meta_description,
  :og => { 
    :url => "#{request.url}", 
    :type => meta_type || "article",
    :title => opts[:title] || meta_title,
    :description => opts[:description] || meta_description,
    :image => (opts[:og] && opts[:og][:image]) || meta_image
  },
  :"csrf-param" => request_forgery_protection_token,
  :"csrf-token" => form_authenticity_token
}
```
