This is my personal fork of the Ruby Red Project. github.com/jessesielaff/red

simple.rb:

require 'red_query'

Document.ready? do
  Document.query('#someDiv').html('hello ruby!!')
end

You need Red and red_query (github.com/julius/red_query) for this to work. Compile it with:

ruby -I$RED_DIR/lib/ $RED_DIR/bin/red -I$RED_QUERY_DIR/ -o simple.js simple

There are a lot of fixes to make more advanced Ruby code run. One Example is calling ‘super’ over more than two levels of inheritance. Many additions and changes are made to make Red fit better into real world scenarios

Here is an example for compilation

ruby -I$RED_DIR/lib/ $RED_DIR/bin/red -I../red_query/ -Ilib -I. -Iapp -o public/js/mycode.js red/mycode

This will compile the file “red/mycode.rb” and will write the output to “public/js/mycode.js” “require”-Statements in Red code will search in all directories marked by -I<dir> (after ../bin/red)

Its nice to reuse code in the frontend and in the backend. E.g.

class User
  def valid_email?(email)
    ...
  end
end

You can also save classes by mixing in some backend only code.

class User
  def valid_email?(email)
    ...
  end

  def login(email, password)
    top_secret_stuff(email)
    screwed_up_backend_code(email, password)
  end
end

You might not want to let Red reveal the login method to hackers. Lets invent some Syntax.

class User
  def valid_email?(email)
    ...
  end

server_side

  def login(email, password)
    top_secret_stuff(email)
    screwed_up_backend_code(email, password)
  end
end

The method login and everything after server_side will be ignored by my Red customization.

I excluded Redshift from my Red version. I believe Red should only have Compilation functionality and it should be open for any kind of Framework, which does DOM-Access etc. I personally started one based on jQuery: github.com/julius/red_query

You can learn more about the great original, gem installable Red on github.com/jessesielaff/red/wikis
