#Sinatra arg

This is a very simple helper for Sinatra allowing you to quickly and easily get each argument within the url path.

##Installation: Install the gem:

gem install sinatra-arg

Require sinatra-arg

require 'sinatra-arg'

Done!

##Usage Anywhere within your Sinatra application you can now call arg() to get the value of any argument. For example if you had the route /blog/2012/11/23/getting-started you could use arg(0) to return blog and arg(4) to return getting-started.

##example require 'sinatra' require 'sinatra-arg'

get '/hello/:name' do
  erb "Hello #{arg(1).capitalize}"
end

get '/goodbye/:name' do
  erb "Goodbye #{arg(1).capitalize}"
end

__END__

@@ layout
<html>
<head>
  <% if arg(0) == 'hello' %>
    <link href="/css/hello.css" rel="stylesheet">
  <% else %>
    <link href="/css/other.css" rel="stylesheet">
  <% end %>
</head>
<body><%= yield %></body>
</html>
