#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>
