CodeRay with Ruby On Rails 3

Code highlight in Ruby On Rails 3 Using CodeRay

First open your Gemfile and add

gem 'coderay'

and run bundle install

bundle install

Next you need to add a method any where you want best place would be ApplicationController

def coderay(text)
  text.gsub(/<code( lang="(.+?)")?>(.+?)<\/code>/m) do
     CodeRay.scan($3, $2).div(:css => :class)
  end
end

Suppose you have controller Post and it's action show
app/controllers/posts_controller.rb

def show
  @post = Post.find(params[:id])
  @post.body = coderay(@post.body)
end

now in view file change following
app/views/posts/show.html.erb

<%= @post.body %>

To

<%= sanitize @post.body %>

Now you need a stylesheet that define color scheme for your code

Ruby On Rails 3 on Fedora 14

Fedora 14(Laughlin) and Rails 3

This post will just let you install only on version of rails on your Fedora 14 that is rails 3 but first we will install rails 2.3.8 from fedora repository. Keep in mind you will able to run only one version of Rails with this method and if you want to run multiple version or installtion than you need to follow on of my old post in which i have used RVM for manging different version of Ruby and also Rails.
Installing and setting up Rails 3 on Fedora 13 (Ruby on Rails 3 RC)

First Installing Ruby 1.8.7 with Rails 2.3.8

[ismail@localhost ~]$ sudo yum install rubygem-rails ruby-devel mysql-devel-y

Now you have running version rails 2.3.8 without mysql database support for rails

Adding mysql rails and ruby support

[ismail@localhost ~]$ sudo yum install ruby-mysql -y

Note: Now you can stop following if you don't want to install rails 3 on fedora 14

upgrading to Rails 3

[ismail@localhost ~]$ sudo gem install rails

If all went cool than you have running version of rails 3 on fedora 14 now create an application and run bundle install to test your installation

[ismail@localhost ~]$ rails new my_app -d mysql
[ismail@localhost ~]$ cd my_app
[ismail@localhost ~]$ bundle install

Have fun with Rails 3 on Fedora 14

ruby 1.9.2 installation on fedora 13 ( also on fedora 14)

Waiting for ruby 1.9.2 or 1.9.1 for fedora?

Your wait have both ended and not. ended in sense now you can install latest release on fedora 13 or fedora 14 using RVM. but bad news is for ruby 1.9.x native install won't come early. Sooner we will have ruby1.8.7 but no chance for ruby 1.9.x so start using ruby1.9.x on rvm if you are curious to that actually really a cool application that can handle multiple ruby version at the same time. if you want to install ruby 1.9.x than you can follow by old post which is about installing ruby on rails 3 on fedora 13.

Ruby on Rails 3 have been released.

Yes Rails 3 have been released and it requires ruby version 1.8.7 or 1.9.2 actually 1.9.1 have number of bugs so rails community recommends you to use 1.9.2 so nor yet ubuntu have ruby 1.9.2 (the day i am posting this post till than ) so you can install using rvm and for installation of rails 3 on fedora you can follow my old post about installing ruby on rails 3 release candidate as rails is released so now you can you use the released version of rails 3. and my previous post will work fine for that. Well if you are running ruby 1.8.7 or above you can install rails 3 by just with single command

sudo gem install rails

Troubling install MySQL with rails 3?

sudo yum install mysql-devel

Use about command in fedora and than install using gem or through bundle install command in your rails project everything will work cool and that will actually install mysql2 driver
