Watir on WebDriver
Jari Bakken just released Watir on WebDriver.
On Windows, install it with
gem install watir-webdriver
and use it with
require "rubygems" # optional require "watir-webdriver" browser = Watir::Browser.new(:firefox)
Supported browsers are Internet Explorer (:ie, :internet_explorer), Firefox (:ff, :firefox), Chrome (:chrome) and RemoteWebDriver Server (:remote).
Update 1: as Steve suggested, I have tried it on RubyInstaller.
Install RubyInstaller, DevKit and all required gems and it just works!
gem install watir-webdriver gem install win32-process
Update 2: It works on Mac.
My Mac came with Ruby and RubyGems installed, so it was just:
sudo gem install watir-webdriver
Update 3: It works on Ubuntu Linux.
My Ubuntu did not have Ruby and RubyGems installed.
Install Ruby with:
sudo apt-get install ruby-full
You can install RubyGems with:
sudo apt-get install rubygems
but Jari said it would be better to install it from source. Downland the latest RubyGems tgz or zip file (rubygems-1.3.5.tgz and rubygems-1.3.5.zip at the moment), extract it, open Terminal in extracted folder and run:
sudo ruby setup.rb
Install watir-webdriver:
sudo gem1.8 install watir-webdriver
Update 4: watir-webdriver is no longer prerelase gem, so installation is simpler.
Ruby Mail and benchmark.rb on CRuby, JRuby, IronRuby and RubyInstaller
Update: Steve suggested I should try the script also with RubyInstaller, and I did it.
This blog post is update of my recent Ruby Mail on CRuby, JRuby and IronRuby post. Mikel and Jimmy have commented on the post saying I did a poor job, and I would agree. I decided to do a better job this time. Please let me know if measurements can be further improved.
So, I have an e-mail file called 1.eml:
Date: Thu, 24 Dec 2009 14:37:34 Central European Standard Time From: from@test.com To: to@test.com Message-ID: <4b336e9e762a0_a1014263a4689d3@2003-ie7.mail> Subject: This is a test email Mime-Version: 1.0 Content-Type: text/plain; charset="US-ASCII"; Content-Transfer-Encoding: 7bit Some text for mail body
The First Try
This is the test from the first post. (RubyInstaller was not included in the first post.) It is included here so all code and numbers are at the same page, I guess it is easier to compare that way. Read the file, display subject and total time elapsed (in seconds).
time = Time.now
require "rubygems"
require "mail"
mail = Mail.read("1.eml")
puts mail.subject.to_s
puts Time.now - time
Executed the script three times for each Ruby implementation. RubyInstaller the fastest, CRuby and JRuby were similar in speed, IronRuby was way slower.

Webalizer on Mac OS X
Yesterday I spend a few hours trying to install Webalizer on Mac OS X 10.6 (Show Leopard), with no luck. After some browsing, I found instructions how to migrate MacPorts, but I got stuck with Error: Checksum (md5) mismatch for jpegsrc.v7.tar.gz. Looks like it is fixed, and Webalizer installed with no problems today with just:
sudo port install webalizer
