Calling IronRuby in F# on Mono

This is just a hobby, but wonderful. Mono 2.10 only can do it as out-of-the-box!

Mono 2.10 has three more languages out-of-the-box

In two days ago, Mono 2.10 had been released. The most notable change is "three more languages out-of-the-box". These are F#,:

IronPython,:

and IronRuby.:

IronRuby 1.1.2 is released

One week ago, IronRuby 1.1.2 has been released. This release fixes many bugs related with RubyGems... here is also about RubyGems!

IronRuby 1.1.1 is released

A few days ago, IronRuby 1.1.1 has been released. It is the first release compatible with Ruby 1.9.2. And now, non-English languages are recognized almost correctly.

IronRuby 1.1 is available, maybe.

IronRuby's latest version is 1.1 (stable version is still 1.0) . This version will be compatible with Ruby 1.9.2.

Really? Show the irb of Ruby 1.9.2.

Next, show the irb of IronRuby 1.1.

Oops, String#encoding is not ready.

re-check "begin-rescue-else-end" on your ruby environment

I found some bug report for JRuby in here (now fixed).

I copy and simplify this sample code like below:

def hoge
  puts 1
rescue Exception => e
  puts 2
  raise "shouldn't get here"
else
  puts 3
  raise "should raise out of the method"
end
begin
  puts RUBY_VERSION
  hoge
rescue => e
  puts e.message
end

Let's evaluate this on each ruby environment.

IronRuby 1.0 is FINALLY released!

A few days ago, IronRuby 1.0 has been released. I download and install IronRuby for .Net 2.0 because My windows environment does not have .NET 4.0.

And I run sample WinForms application from IronRuby console:

IronRuby 1.0.0.0 on .NET 2.0.50727.4927

>>> require 'System.Windows.Forms'
=> true
>>> include System::Windows::Forms
=> Object
>>> f = Form.new
=> System.Windows.Forms.Form, Text:
>>> f.text = 'Hello World'
=> "Hello World"
>>> Application.run(f)

Gestalt and Moonlight

I learned 'Gestalt' recently - that is browser-side Ruby/Python/XAML scripting (instead of ECMAScript) driven with jQuery and Silverlight. Is that the product only for Windows? No! Gestalt supports not only Silverlight but also Moonlight.

I try to run sample bundled with Gestalt onto the Firefox on the my openSUSE.

1. Install Firefox add-on of moonlight from here
2. Download the zip of Gestalt from here
3. Uncompress the zip of Gestalt
4. Open the XAML sample files Gestalt/samples/getting.started/03_xaml.html, Gestalt/samples/getting.started/04_animation.html and Gestalt/samples/getting.started/05_final.html

If Gestalt/samples/getting.started/03_xaml.html succeeded, Firefox renders like below:

But samples of Ruby or Python didn't work in intact. I guess it's suspicious that Moonlight on the openSUSE 11.1 is 1.0, not 2.0 even though Firefox add-on of moonlight is 2.0 beta.
