What separates Raakt from other accessibility evaluation tools is that only Tests that are machine verifiable are included. Text processing with Ruby. On the same page as Perl or Python, Ruby has great capabilities to be a powerful text processing language.

This article briefly talks about the textual data processing abilities of Ruby and how you can use it to efficiently handle different formats of textual data, whether CSV data or XML data. Ruby strings Strings in Ruby are a powerful way to hold, compare, and manipulate textual data. In Ruby, String is a class that you can instantiate by invoking String::new or by just assigning a literal value. When you assign values to Strings, you can use a pair of single quotes (') to enclose the value, or a pair of double quotes ( "" ). Listing 1 is an example.

I’ve been reading a lot of Rakefiles lately, and it’s obvious that the folks writing them think of Rake as An Engine For Encapsulating Tasks.

That’s fine, but it’s only part of what Rake can do. I Do Declare Rake is all about resolving dependencies. It’s about being declarative, not imperative. Especially when dealing with files and directories, this can make a huge difference. Desc "Make sure your database.yml is in place"task :wheres_your_database_yml do unless File.exists? (This is from technicalpickles’ dude-wheres-your-database-yml, a nice little Rails plugin for automatically installing a database.yml file the first time a new contributor runs Rake.

I use RSpec in all my projects.

It’s really hard to overemphasize how helpful it is and how much easier becomes your life if you have good specs coverage. But its outstanding flexibility enables many ways to make your specs awful: horribly slow, over-bloated, even non-readable sometimes. I do not want to teach you BDD and RSpec here, but instead I will give you some ideas how to improve your specs quality and increase efficiency of your BDD workflow. 1. Use before :all block carefully Sometimes it looks like a good idea to create a test data in before :all block. Another option is to move your before :all blocks to before :each to make them rolled back automatically. 2. Ruby Application Archive. RIOT - testing ruby. Ruby at ThoughtWorks.

ThoughtWorks started using Ruby for production projects in 2006, from then till the end of 2008 we had done 41 ruby projects.

In preparation for a talk at QCon I surveyed these projects to examine what lessons we can draw from the experience. I describe our thoughts so far on common questions about Ruby's productivity, speed and maintainability. So far our conclusions are that Ruby is a viable platform that should be seriously considered for many forms of applications - in particular web applications using Ruby on Rails. I also go through some technical lessons, including some thoughts on testing with Active Record.

ThoughtWorks, my employer, is primarily a software delivery company. A few people, however, had started experimenting with LAMP scripting languages, in particular Ruby. During these three years we've learned a lot about Ruby in practice. I've divided the article into three parts. Rails Wiki => Rails Wiki. Sipper - Create any callflow.

Lucas Catón » [Tutorial] Traduzir rotas do Ruby on Rails com o plugin translate_routes.

Neste tutorial vou ensinar como traduzir rotas no Ruby on Rails, usando um plugin chamado translate_routes. No Rails, uma boa prática é usar o inglês para nomear controllers, models, views, layouts, helpers, etc. O problema é que às vezes não fica legal deixar as URLs em inglês, principalmente quando você vai desenvolver um site estático (um site institucional por exemplo), o seu cliente pode não gostar. É aí que entra o plugin “translate_routes”. Nós traduziremos somente as URLs públicas, porém todo código backend não será afetado. Ah! Atenção: os comandos de terminal que são usados neste tutorial foram feitos no Linux, embora pouca coisa mude no Mac ou no Windows. Então, mãos à obra: 1. 2. 3. 4.

O Guia (comovente) de Ruby do Why. Gedit com cara de TextMate. Atualizado em: 19/03/2010 Para desenvolver com Ruby on Rails em Linux uma boa alternativa para editores de texto é o Gedit com alguns plugins. Longe de ficar igual ao TextMate, mas digamos que assim dá um “gostinho a mais” para escrever alguns códigos, logicamente o intuito aqui não é mudar a “cara” do Gedit somente, mas sim utilizar algumas ferramentas para tornar mais ágil o desenvolvimento, como atalhos, auto-completar de textos, busca rápida de arquivos dentro do projeto, etc. Rails Envy.
