## Installation

```
gem install sinatra-subdomain
```

## Usage

```ruby
require "sinatra"
require "sinatra/subdomain"

# Specify which subdomain you want
subdomain :foo do
  get "/" do
    "render page for FOO"
  end
end

# If any subdomain is set
subdomain do
  get "/" do
    "render page for #{subdomain} subdomain"
  end
end
```

If you're not building a classic app, make sure to register Sinatra::Subdomain yourself:

```ruby
require "sinatra"
require "sinatra/subdomain"

# Specify which subdomain you want
class MyApp < Sinatra::Base
  register Sinatra::Subdomain

  subdomain :foo do
    get "/" do
      "render page for FOO"
    end
  end

  # If any subdomain is set
  subdomain do
    get "/" do
      "render page for #{subdomain} subdomain"
    end
  end
end
```

You can also pass an array or regular expressions to match subdomains:

```ruby
class MyApp < Sinatra::Base
  register Sinatra::Subdomain

  subdomain [:foo, :bar, :zaz] do
    get "/" do
      "render page for #{subdomain}"
    end
  end

  # Matches www, www1, www2, etc.
  subdomain /\Awww\d*\z/ do
    get "/" do
      "render page for #{subdomain} subdomain"
    end
  end
end
```

By default, sinatra-subdomain will consider 1 TLD as in <tt>example.com</tt>.
You can specify your TLD size for domains like <tt>example.com.br</tt> or <tt>example.co.uk</tt>.

```ruby
require "sinatra"
require "sinatra/subdomain"

set :tld_size, 2
```
