#rubinius

RubySpec 프로젝트가 MRI 진영의 참여 저조로 끝나면서 많은 구현체들이 참조할 수 있는 테스트 프레임워크가 사라진 셈이었는데, Ruby 진영에서 논의 끝에 RubySpec을 부활시키기로 결정. 포크 저장소인 ruby/rubyspec이 생겼다.

Yesterday, I was reading my timeline on twitter when I saw a tweet - precisely, this one - which made me curious about it.

So, I went to Rubinius page and download the package for Mac OSX (yep, I'm using OSX, but you can use it on Linux too... unless you're using Windows. In this case, I highly recommend to you: use a Linux distro.

Well, installed the .pkg (package format for OSX) and tested it on terminal:

rbx -v

Will print something like:

rubinius 1.2.4 (1.8.7 release 2011-07-05 JI) [x86_64-apple-darwin10.7.4]

Notes:

It's easy and recommend install rubinius through RVM. Seriously. Of course, If you pretend to use different ruby versions on your computer.

To install through rvm you have to - of course - install RVM (installation guide here) first and then run the following in your terminal:

rvm install rbx-master

And to use it (if you aren't familiar with the RVM premise, go google about it):

rvm use rbx

Which will output something like this

Using /Users/{your_user_name}/.rvm/gems/rbx-master

Notes:

Rubinius uses the 1.8.7 dev version of Ruby

Some Rails versions won't work with him.

Rubinius plus Rails

Ok, let's take an test case for rubinius (just compile a .rb file doesn't show his potential):

Rails app: I'm working in an app for a customer right here in Brazil. Here is the gemfile configuration:

It's Rails 3.0.9

As in Development mode, I'm using SQLite3

Uses HAML and SASS for templating

Other ~gems~ like Devise, Simple_form, Bourbon, and many others.

To use Rubinius in this app, I had to do the following:

rvm use rbx bundle install

(P.S.: bundle install to install the gems under Rubinius gemset)

And then, run the app, normally:

rails s

Oh-oh problems

If you see an error when starting the rails server command, check if you're using a .rvmrc in the app root folder. Switch the ruby's version to 1.8.7 (rmv use system) if necessary.

Oh-oh problems2

When I switched to browser (accessing http://host:port), an error occured:

TemplateError: Cannot modify SafeBuffer in place

Perhaps an error in HAML version? In earlier versions (<~ 3.1.2), HAML was using gsub! instead of gsub and that was the main cause which throws this kind of error. But no, isn't HAML. Update to Rails 3.1 and your problem is solved.

Notes:

WOW. My application now is running pretty fast, almost "instantly" to load all the pages

Rubinius compiles bytecode to machine code. You'll see some *.rbc files in your project tree. They are the compiled files.

GemAWeek Episode 8 - Rubinius Day

This week's episode is a little different. In celebration of Rubinius Day, I wanted to show how easy it is to create a gem and used Rubinius to do so. This is based on Steve Klabnik's presentation called Teachmehowtomakearubygem.
