Building and Packaging Extensions

Sinatra extensions should be built as separate libraries and packaged as gems or as single files that can be included within an application’ s lib directory. The ideal process for using an extensions is installing a gem and requiring a single file.

The following is an example file layout for a typical extension packaged as a gem:

|-- .gitignore
|-- sinatra-fu.gemspec
|-- Rakefile
|-- README.markdown
|-- TODO
|-- lib
|   `-- sinatra
|       `-- fu.rb
|-- test
|   `-- spec_sinatra_fu.rb
`-- examples
    |-- app.rb
    |-- config.ru
    `-- app-base.rb

Plik sinatra-fu.gemspec:

require 'rake'

Gem::Specification.new do |s|
  s.name = "sinatra-fu"
  s.version = '0.0.1'
  s.date = '2009-03-31'

  s.summary = "Sinatra-Fu yields fu method for escaping html"
  s.email = "matwb@univ.gda.pl"
  s.homepage = "http://github.com/wbzyl/sinatra-fu"
  s.description = "Sinatra-Fu yields missing h method for escaping html"
  s.authors = ["Włodek Bzyl"]
  s.files = FileList[".gitignore", "[A-Z]*", "{lib,test,examples}/**/*"]

  s.add_dependency 'sinatra', '>=0.9.1'
  s.add_dependency 'rack', '>=0.9.1'

  s.rubygems_version = '1.3.1'

Plik fu.rb:

require 'sinatra/base'

module Sinatra
  module HTMLFuHelper
    def fu(text)

  helpers HTMLFuHelper

Plik app.rb:

require 'rubygems'
require 'sinatra'
require 'sinatra/fu'

get "/" do
  fu "1 < 2"     # => "1 &lt; 2"

Aplikację uruchamiamy tak:

ruby app.rb -p 4567

Plik app-base.rb:

require 'rubygems'
require 'sinatra/base'
require 'sinatra/fu'

class HelloApp < Sinatra::Base
  helpers Sinatra::HTMLFuHelper

  get "/" do
    fu "1 < 2"

Plik config.ru:

#\ -p 4000 -s thin
require 'app-base'
run FuApp.new

A tę aplikację uruchamiamy tak:

rackup config.ru -p 4000

albo tak:

thin --rackup config.ru start -p 4000
