Creates a Rack::Builder instance with all the middleware set up and an instance of this class as end point.
# File lib/sinatra/base.rb, line 1381 def build(builder, *args, &bk) setup_default_middleware builder setup_middleware builder builder.run new!(*args, &bk) builder end
# File lib/sinatra/base.rb, line 1388 def call(env) synchronize { prototype.call(env) } end
Like Kernel#caller but excluding certain magic entries and without line / method information; the resulting array contains filenames only.
# File lib/sinatra/base.rb, line 1495 def caller_files cleaned_caller(1).flatten end
Like ::caller_files, but containing Arrays rather than strings with the first element being the file, and the second being the line.
# File lib/sinatra/base.rb, line 1501 def caller_locations cleaned_caller 2 end
Set configuration options for Sinatra and/or the app. Allows scoping of settings for certain environments.
# File lib/sinatra/base.rb, line 1327 def configure(*envs, &block) yield self if envs.empty? || envs.include?(environment.to_sym) end
# File lib/sinatra/base.rb, line 1229 def delete(path, opts={}, &bk) route 'DELETE', path, opts, &bk end
# File lib/sinatra/base.rb, line 1321 def development?; environment == :development end
Defining a `GET` handler also automatically defines a `HEAD` handler.
# File lib/sinatra/base.rb, line 1219 def get(path, opts={}, &block) conditions = @conditions.dup route('GET', path, opts, &block) @conditions = conditions route('HEAD', path, opts, &block) end
# File lib/sinatra/base.rb, line 1230 def head(path, opts={}, &bk) route 'HEAD', path, opts, &bk end
Makes the methods defined in the block and in the Modules given in `extensions` available to the handlers and templates
# File lib/sinatra/base.rb, line 1305 def helpers(*extensions, &block) class_eval(&block) if block_given? include(*extensions) if extensions.any? end
# File lib/sinatra/base.rb, line 746 def initialize(app=nil) super() @app = app @template_cache = Tilt::Cache.new yield self if block_given? end
Create a new instance of the class fronted by its middleware pipeline. The object is guaranteed to respond to call but may not be an instance of the class new was called on.
# File lib/sinatra/base.rb, line 1375 def new(*args, &bk) build(Rack::Builder.new, *args, &bk).to_app end
Create a new instance without middleware in front of it.
# File lib/sinatra/base.rb, line 1231 def options(path, opts={}, &bk) route 'OPTIONS', path, opts, &bk end
# File lib/sinatra/base.rb, line 1232 def patch(path, opts={}, &bk) route 'PATCH', path, opts, &bk end
# File lib/sinatra/base.rb, line 1228 def post(path, opts={}, &bk) route 'POST', path, opts, &bk end
# File lib/sinatra/base.rb, line 1322 def production?; environment == :production end
The prototype instance used to process requests.
# File lib/sinatra/base.rb, line 1365 def prototype @prototype ||= new end
# File lib/sinatra/base.rb, line 1227 def put(path, opts={}, &bk) route 'PUT', path, opts, &bk end
# File lib/sinatra/base.rb, line 1337 def quit!(server, handler_name) # Use Thin's hard #stop! if available, otherwise just #stop. server.respond_to?(:stop!) ? server.stop! : server.stop $stderr.puts "\n== Sinatra has ended his set (crowd applauds)" unless handler_name =~%rcgi/ end
Register an extension. Alternatively take a block from which an extension will be created and registered on the fly.
# File lib/sinatra/base.rb, line 1312 def register(*extensions, &block) extensions << Module.new(&block) if block_given? @extensions += extensions extensions.each do |extension| extend extension extension.registered(self) if extension.respond_to?(:registered) end end
Run the Sinatra app as a self-hosted server using Thin, Mongrel or WEBrick (in that order). If given a block, will call with the constructed handler once we have taken the stage.
# File lib/sinatra/base.rb, line 1346 def run!(options={}) set options handler = detect_rack_handler handler_name = handler.name.gsub(%r.*::/, '') handler.run self, :Host => bind, :Port => port do |server| unless handler_name =~ %rcgi/ $stderr.puts "== Sinatra/#{Sinatra::VERSION} has taken the stage " + "on #{port} for #{environment} with backup from #{handler_name}" end [:INT, :TERM].each { |sig| trap(sig) { quit!(server, handler_name) } } server.threaded = settings.threaded if server.respond_to? :threaded= set :running, true yield server if block_given? end rescue Errno::EADDRINUSE $stderr.puts "== Someone is already performing on port #{port}!" end
Access settings defined with Base.set.
# File lib/sinatra/base.rb, line 784 def self.settings self end
# File lib/sinatra/base.rb, line 1323 def test?; environment == :test end
Use the specified Rack middleware
# File lib/sinatra/base.rb, line 1332 def use(middleware, *args, &block) @prototype = nil @middleware << [middleware, args, block] end
Rack call interface.
# File lib/sinatra/base.rb, line 754 def call(env) dup.call!(env) end
Forward the request to the downstream app – middleware only.
# File lib/sinatra/base.rb, line 814 def forward fail "downstream app not set" unless @app.respond_to? :call status, headers, body = @app.call env @response.status = status @response.body = body @response.headers.merge! headers nil end
Exit the current block, halts any further processing of the request, and returns the specified response.
# File lib/sinatra/base.rb, line 801 def halt(*response) response = response.first if response.length == 1 throw :halt, response end
# File lib/sinatra/base.rb, line 793 def options warn "Sinatra::Base#options is deprecated and will be removed, " "use #settings instead." settings end
Pass control to the next matching route. If there are no more matching routes, Sinatra will return a 404 response.
# File lib/sinatra/base.rb, line 809 def pass(&block) throw :pass, block end
Access settings defined with Base.set.
# File lib/sinatra/base.rb, line 789 def settings self.class.settings end
