I tried The Camping Short, Short Example for the ruby camping framework.

#!ruby
 #!/usr/local/bin/ruby -rubygems
 require 'camping'

 Camping.goes :HomePage

 module HomePage::Controllers

   # The root slash shows the `index' view.
   class Index < R '/'
     def get
       render :index
     end
   end

   # Any other page name gets sent to the view
   # of the same name.
   #
   #   /index -> Views#index
   #   /sample -> Views#sample
   #
   class Page < R '/(\w+)'
     def get(page_name)
       render page_name
     end
   end

 end

 module HomePage::Views

   # If you have a `layout' method like this, it
   # will wrap the HTML in the other methods.  The
   # `self << yield' is where the HTML is inserted.
   def layout
     html do
       title { 'My HomePage' }
       body { self << yield }
     end
   end

   # The `index' view.  Inside your views, you express
   # the HTML in Ruby.  See http://code.whytheluckystiff.net/markaby/.
   def index
     p 'Hi my name is Charles.'
     p 'Here are some links:'
     ul do
      li { a 'Google', :href => 'http://google.com' }
      li { a 'A sample page', :href => '/sample' }
     end
   end

   # The `sample' view.
   def sample
     p 'A sample page'
   end
 end

It seems to be very easy to create the separat pages.

The example above generates one entry page. (the index method in Views) and one additional page (sample method).
As far as i should know it from rails, it uses the same MVC pattern and theres is a similar syntax. Just the Views are in native ruby without mixing up with html.
But maybe that will appear later on.
The next step is to see howto connect ruby with some inner sys-functions of nexenta ^^.

Just a short one:

Just easy as this:

  root@sunny:~# gem install camping –source http://code.whytheluckystiff.net
    …
    Installing ri documentation for markaby-0.5…
    Installing ri documentation for camping-1.5.180…
    Installing RDoc documentation for activesupport-1.4.2…
    Installing RDoc documentation for builder-2.1.1…
    Installing RDoc documentation for markaby-0.5…
    Installing RDoc documentation for camping-1.5.180…

Smooth and easy. Ready to rumble ;-).

Next in the row is the installation of the ruby gems package.
So it should be easy… just following the instructions.
So…..

root@sunny:~# wget http://rubyforge.org/frs/download.php/38647/rubygems-1.2.0.zip
root@sunny:~# unzip rubygems-1.2.0.zip
root@sunny:~# cd rubygems-1.2.0
root@sunny:~# ruby setup.rb config
./lib/rubygems/spec_fetcher.rb:1:in `require’: no such file to load — zlib (LoadError)
from ./lib/rubygems/spec_fetcher.rb:1
from ./lib/rubygems/source_index.rb:10:in `require’
from ./lib/rubygems/source_index.rb:10
from ./lib/rubygems.rb:767:in `require’
from ./lib/rubygems.rb:767
from setup.rb:22:in `require’
from setup.rb:22

Welcom to error world ;-).
Okay…. should be easy to solve:

root@sunny:~# apt-get install libzlib-ruby zlib1g-dev

or for 64bit Plattforms:

root@sunny:~# apt-get install libzlib-ruby lib64z1-dev

But still the same Error!
Finally i found something in the Weblog of Lucas Chan.
Hm its about readhat/centos…. okay why not.
Just go to the ruby sources:

root@sunny:~# cd /usr/local/src/ruby-1.8.6-p110/
root@sunny:~# cd ext/zlib
root@sunny:~# ruby ruby extconf.rb –with-zlib-include=/usr/include –with-zlib-lib=/usr/lib
checking for deflateReset() in -lz… yes
checking for zlib.h… yes
checking for kind of operating system… Unix
creating Makefile

root@sunny:~# make
root@sunny:~# make install

and finally:

root@sunny:~# cd /usr/local/src/rubygems-1.2.0/
root@sunny:~# ruby setup.rb config
….
== Thanks

Keep those gems coming!

Again: something learned!

If you want to build your own small ruby script for administrating you Nexenta-Box, you normally just have to do a:

root@sunny:~# apt-get install ruby

Unfortunetally this Package seems to be broken:

root@sunny:~# ruby -v
ld.so.1: ruby1.8: fatal: libruby1.8.so.1: open failed: No such file or directory

The needed lib libruby1.8.so.1 is not on its desired place.
So you need to compile yourself a version of ruby:

root@sunny:~# apt-get remove ruby
root@sunny:~# apt-get autoremove
root@sunny:~# apt-get install build-essential

root@sunny:~# cd /tmp
root@sunny:~# wget ftp://ftp.ruby-lang.org/pub/ruby/1.8/ruby-1.8.6-p110.tar.gz

root@sunny:~# tar xvfz ruby-1.8.6-p110.tar.gz
root@sunny:~# cd ruby-1.8.6-p110

root@sunny:~# ./configure
root@sunny:~# make
root@sunny:~# make test-all
root@sunny:~# make install
root@sunny:~# make install-doc

/usr/local/bin should be in your path!

root@sunny:~# echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/bin/X11

root@sunny:~# make install-doc

root@sunny:~# which ruby
/usr/local/bin/ruby
root@sunny:~# ruby -v
ruby 1.8.6 (2007-09-23 patchlevel 110) [i386-solaris2.11]

DONE!
