Sinatra NAmed Paths (snap)

Enables named paths in Sinatra apps.

The SNAP extension is a solution for named paths in Sinatra. It also provides helper methods to build URLs and perform parameter substitution.

Install the gem:

sudo gem install sinatra-snap

Then require it in your application and use away!

require 'rubygems'
require 'sinatra'
require 'sinatra-snap'

paths :add => '/add/:addend/:augend',
      :sum => '/sum/:addend/:augend',

:subtract => ‘/subtract//’, :difference => %r{/difference/(\d+)/(\d+)}

get :add do
  redirect path_to(:sum).with(params[:addend], params[:augend])
end

get :sum do
  "#{params[:addend]} + #{params[:augend]} = #{params[:addend].to_i + params[:augend].to_i}"
end

get :subtract do
  redirect path_to(:difference).with(params[:splat][0], params[:splat][1])
end

get :difference do
  "#{params[:captures][0]} - #{params[:captures[1]]} = #{params[:captures][0]].to_i - params[:captures][1]].to_i}"
end
