RailsInstaller is Instant Rails Evolved

Posted on January 17, 2011 Written by 1 Comment

Today the great team led by Wayne Sequin (rvm fame) and Luis Lavena (RubyInstaller fame)  and initiated by Dr. Nic Williams of Engine Yard released RailsInstaller.

In the Box

RailsInstaller is really what Instant Rails brought to Windows developers wanting to write Ruby and Ruby on Rails code, but now evolved.  RailsInstaller takes Ruby and Rails to their current versions and add some other niceties to give the Windows developer the ability to create real Rails applications today.  Included is:

  • Ruby 1.8.7-p330
  • Rails 3.0.3
  • Git 1.7.3.1
  • Sqlite 3.7.3
  • DevKit

I would expect that we would see a Ruby 1.9.2 at some point but imagine there must be some technical hurdles to get beyond before it makes sense to release.

Installation

Installation is a breeze by just following the simple installation wizard all Windows users know all about.   A nice video has been created to show how to install and get started:

The video is very clear and the installation wizard really simple, just follow the directions and keep the defaults for the best experience.

RailsInstaller1

The installer explains clearly what is being installed in this particular version.

RailsInstaller2

The default is to add to the PATH statement.  I would recommend keeping this so your system knows where to find all the needed executables.

RailsInstallerMenu

You should notice a nice shortcut to a Ruby and Rails prompt all setup to use.

RailsInstallerPrompt

The Ruby version as well as the Git version are cleanly shown.  You are good to go.

I was lucky enough to have a prerelease build of the tool and even in a prerelease state, they guys did a great job.  It was easy to create Rails apps and have them running in no time.  Keep in mind that not all Ruby gems will yet be compatible with Windows.  If you encounter issues you are best advised to contact the person in charge of the gem project you are trying to install.

I encourage everyone to who is interested in Rails on Windows in a clean package to download the installer now and give it a go.

6 Great Ruby on Rails 3 Learning Resources

Posted on November 15, 2010 Written by 6 Comments

Ruby on Rails 3 was released just a short time ago and is a fairly big changed to previous versions of the Rails framework.   People are starting to put together some great content to help developers come up-to-speed on Rails 3.

I began looking around for some Rails 3 content for my own use, even though I use a variety of beta books for the purpose, I found these resources really useful.  This brought me to the realization some readers may find value.

1. Ruby on Rails Tutorial by Michael Hartl

railstutorial_logoThis is such a great resource; offering a range of content that includes a Ruby on Rails Tutorial book as well as a set of videos with material from the book.  The book is available to read on-line, purchase as a PDF or the dead tree version available from Addison-Wesley.

The videos are a real sweet spot in my opinion, with 15 hrs of video training for $85.  Try to get 2-days of training from anyone at that price.

Table of Contents

  • Rails installation (OS X/Linux) (13m)
  • Git .bashrc lines
  • Rails installation (Windows) (8m)
  • Lesson 1: From zero to deploy (46m)
  • Lesson 2: A demo app (1h11m)
  • OS X testing setup (8m)
  • Lesson 3: Mostly static pages (57m)
  • Lesson 4: Rails-flavored Ruby (1h45m)
  • Lesson 5: Filling in the layout (1h10m)
  • Lesson 6: Modeling and viewing users, part I (1h30m)
  • Lesson 7: Modeling and viewing users, part II (1h40m)
  • Lesson 8: Sign up (1h22m)
  • Lesson 9: Sign in, sign out (1h36m)
  • Lesson 10: Updating, showing, and deleting users (2h25m)
  • Lesson 11: User microposts (2h03m)
  • Lesson 12: Following users (2h19m)

I have gone through both the book, Rails 3 version, and the screencasts looking for nuggets of information I may not be aware of in Rails 3.  The screen casts are presented in a such a well-thought-out manner that makes them easy to follow and will not put you to sleep.

Michael covers a lot of great basic topics but also includes specific coverage of such things as setting up and using Devise for authentication.  He also covers Test-Driven Development (TDD) very well using RSpec.  There are a lot of how-to tips with TDD alone to save you hours.

2. PeepCode: Meet Rails 3 Part 01

meet-rails-3-iI always love the content put out by PeepCode and Geoffrey Grosenbach and his recent Meet Rails 3 Part 01 was no exception.

This screen cast covers the beginning aspects of getting into Rails development both on Mac and Windows.  I was pleasantly surprised to see my blog post Running Rails 3 on Windows was used as a reference for users to setup and use Rails 3 on Windows.

PeepCode has been providing screencasts for a long time and is likely to the first to offer those covering Ruby on Rails.

3. Dive into Rails 3 Screencasts

Episode1The Dive into Rails 3 screencasts put out by Gregg Pollack were probably the first series focused on Rails 3 right around the time Rails 3 was released.

Gregg covers many of the hot topics emerging in Rails 3 today:

These are screencasts talk about what is new in Rails 3, so some knowledge of Rails 2.x would be helpful to get the most out of these.

4.  RailsCasts

railscasts_logoRyan Bates has been making the weekly release of a RailsCast what seems like forever now.  Currently there are 240 episodes up on the site, and by my precise calculations..that’s around 4 1/2 years of  great content.  Most episodes range between 10 and 15 minutes of focused content on a particular topic.

At last count Ryan had 25 screen casts covering different aspects of Rails 3 from the basics to new validations to implementing Devise.  These episodes are laser focused to they are best used with some prior knowledge first, possibly go through the Tekpub or RailsTutorial first.

5. TekPub Rails 3 Series

tekpub_logo_smThe Rails 3 series from TekPub currently has 6 episodes running 5+ hours.  The typical series from TekPub is one that starts off with a single episode with more added over a few weeks.

I have been a Tekpub subscriber since it first opened in October 2009 and love the format of their training.

This series is promoted as:

In this series Rob Conery shows you Rails 3 and the core concepts involved. The focus of this series is a bit more practical than theoretical – with the goal of showing you not only Rails, but many of the tools to help you get your site up and running quickly and effectively.

Rob has a been doing screencasts for a long time and has really honed his voice to be the soothing voice you hear on each episode.  Each episode is on a different topic and covers it very well in the 1 hour dedicated.  As I write this, Rob has 6 episodes:

  1. Why You Should Care About Rails 3
  2. Rack
  3. Controller Fundamentals
  4. Controller Deep Dive
  5. View Concepts
  6. Model Concepts

6. Rails 3 Upgrade Handbook

rails-3-upgrade-handbook-pdf

Long-time Ruby and Rails community member Jeremy McAnally has written up this great handbook on how to take your pre-Rails 3 application into the Rails 3 world.

So many projects exist out in the wild that his handbook is invaluable.

Unlike the other resources I have listed, this is not a screencast but is available as an ebook.   I felt is was just such a great resource for Rails 3 and it tied in so well with coming up-to-speed on Rails 3 and the likelihood you might be upgrading a Rails 2.x application to the latest.

The guide is a beauty, it really covers the pain points a developer will face when upgrading their application to Rails 3 and shows how to get around them.  He includes use of his gem to help with the process as well as checklists for deprecations and the upgrade process itself.

Moving your application to Rails 3?  You need this guide.

Running Rails 3 on Windows

Posted on September 1, 2010 Written by 35 Comments

Well, the long-awaited release of Ruby on Rails 3 is now out and all of the Mac and Linux junkies are busy gem-installing the latest version of the framework.  What about all the lonely Windows developers out there looking through their windows (pun intended) and wondering what it’s like on the other side of the fence?

Good news!  It is actually pretty easy to setup and run Rails 3 on your Windows system.  I mainly run on Macs these days but have a couple Windows systems still kicking around and thought I would give a go.  It is actually pretty straight-forward now and works really well.  Follow the steps:

Install Ruby

Rails 3 requires at least Ruby 1.8.7 and is happy using Ruby 1.9.2, I opted for the latest and greatest.

  1. Head over to RubyForge for the Ruby Installer by Luis Lavena.  Download 1.9.2-p0 for the latest.   A nice feature of this Ruby installer is the latest gem executable is built in, which is version 1.3.7 at the time of this writing and you won’t have to install it yourself.
  2. I installed in C:\Ruby192, which is the default, and added C:\Ruby192\bin to my path so Windows can find the Ruby executables.

Running the Ruby version command from a new command prompt:

ruby -v

ruby-version

If you get a file-not-found or some other undesirable result then the path setting isn’t likely correct or you may want to try closing the command prompt and opening a new one.

Install Ruby on Rails

This is a tough one:

gem install rails

UPDATE: A reader points out of issues with installing Rails as pointed out by a post on the Ruby Forum. The issue was solved by simply adding a –pre to the gem command to install Rails.

gem install rails --pre

Everything you need to run Rails 3 gets installed with the exception of the SQLite3 Ruby gem which Rails uses as the default database provider:

Rails3gems

gem install sqlite3-ruby

You should see a message similar to this:

sqlite3-ruby-gem

I use SQLite3 for most of my local development unless I need a database like MySQL or PostgreSQL.  Installing is trivial.

Installing SQLite3

If you look at the above message when installing the sqlite3-ruby you should notice the gem relies on the sqlite3.dll and it is recommended to use version 3.6.23.1, which you can download form here.  I grabbed 3.7.2 and it seems to work fine, your mileage may vary.  If you’re interested, get the latest from the SQLite3 downloads page.

Now with the sqlite3.dll in hand (unzipped from the download), copy to the bin directory of the above Ruby installation.  In my case that’s C:\Ruby192\bin, and that’s it.

Creating a Test Application

Now it’s time to test the new Ruby and Rails installation.  Pick a location to create the new application and run the new Rails command from a command prompt:

rails new testapp

This command creates a new directory called testapp and spits out a bunch of text along the way, looking something like this:

railsapp

Once done, change directory into the new testapp directory and run:

rake db:migrate

This will test your SQLite3 installation and create a new development database in the testapp\db directory called development.sqlite3.  If you get any errors it is likely the sqlite3.dll is not in your Ruby bin directory, check and come back.

Now from the testapp directory, fire up the Rails development server from a command prompt:

rails server

WebBrick fires up and looks like this:

rails_server

If there are errors reported than something has gone wrong.  If you see this screen, fire up your browser and browser to the address http://localhost:3000.  If all goes well, you will see this screen:

testapp_home

Click on the link below the title that reads “About your application’s environment”.  This gives a lot of detail about your Rails application configuration.

testapp_config

Congratulations!  You have the latest and greatest Ruby and Ruby on Rails running on the Windows platform.

Now go out and read Mike Hartl’s Ruby on Rails Tutorial for Rail 3 and create some applications.

RailsConf 2010

Posted on June 14, 2010 Written by 1 Comment

RailsConf 2010 was this past week in Baltimore, MD.  I decided to make the trip down from CT since it was only about 5 hours by train.  Many people have already covered the conference around the interwebs and I am not doing it here.

I had a great time, meeting many new friends and catching up with some old ones.  I arrived on Sunday evening and attended the Ignite RailsConf event.  This event had excellent content and was well attended with about 200 people coming out.

Monday came and we had a full schedule of 3-hour tutorial sessions.  These were good but the unfortunate thing about multi-track events is missing some sessions I would like to see.  It appears the keynotes were the only sessions being recorded, which is too bad.

Keynotes

The keynotes were really one of the highlights of the event for me.  I get the most out of these as they are typically by members of the software development community which are not necessarily Ruby or Rails related. The exception here was really Gary Vaynerchuck, which I missed because I was traveling home.  Thankfully, O’Reilly was recording these sessions and I can watch when I have the time.

Anyone who did not attend RailsConf should check out the recorded keynote sessions from DHH, Yehuda Katz, Derek Sivers, Robert Martin, Gary Vaynerchuck, Michael Feather, Neal Ford and Evan Phoenix.

Sessions

The sessions were overall pretty good and I enjoyed the ones I attended, but I wish I could see other sessions than just the ones I attended.  I think we should petition O’Reilly to record all talks.

Attending all these sessions during the week were really exhausting.  As I write this on Saturday I still feel tired and imagine I won’t feel rested for a few days.

Hallway Chatter and Meeting New Friends

I have come to learn that the real value of any conference is not the knowledge acquired while attending the sessions but the friends and acquaintances we see and the new relationships formed.

I met many people who I knew only from the online world, interacting on my blog or Twitter.  I was fun to see how the people looked different than their Twitter pictures, many look very different.

Finally

I did have a good time at RailsConf but it was exhausting.  As I write this today I am still really tired from the 5 days I was away.

I find it interesting how people take in a conference, how they spend their time.  As I attended talks I looked around the room to see a sea of Apple logos of the MacBooks in the audience.  I noticed people with their MacBooks spending the session writing code, surfing the web or using Twittering.  I repeatedly wondered why people make the effort to attend a session yet do something other than pay attention to the speaker.

I have been to both large and small conferences and especially after this RailsConf, I keep think that smaller single track conferences are the way to go if you want the chance to have a richer environment.  I missed several people I wanted to meet but never ran into them, which goes to show the size of the group.  Smaller conferences typically have 100-200 people and gives attendees a better chance of seeing everyone.

I am looking forward to attending more computer science and engineering related conferences this year as well as some business-specific ones such as BizConf.  I think these are the types of conferences I will gain more value from, rather than simply Ruby-specific.  I hope to see you at a conference soon.

To Rails 3 or Not to Rails 3, That Is The Question

Posted on May 20, 2010 Written by 15 Comments

The release of the web framework, Ruby on Rails 3, may lead to some pretty interesting decisions for current Rails developers.

The description of Rails 3 from the Agile Web Development with Rails 4th Edition (beta) book from the Pragmatic Programmers web site sums it up pretty well:

Rails 3 is a major release—the changes aren’t just incremental, but structural. So we decided to follow suit. This book isn’t just a mild reworking of the previous edition to make it run with the new Rails. Instead, it’s a complete refactoring.

Rails 3 introduces many new things, many new conventions.  Version 3 looks more like a new framework, rather than just a version upgrade.  Previously, the amount of effort to move from one Rails version to another was pretty small and unit tests helped reveal problems.  We still rely on our unit tests for this purpose but the effort is not as small.

Rails 3 does offer many fantastic new features and the new architecture attempts to fix problems and areas where the current Rails framework falls short, but at what cost?   I have heard people say over and over, moving to Rails 3 is difficult.  Will this prevent migrating projects to Rails 3?

Jeremy McAnally has written a great ebook titled Rails 3 Upgrade Handbook where he outlines the tasks developers will face when moving existing Rails applications from version 3.   To quote Jeremy from the book about moving applications to Rails 3:

The new features, performance improvements, and API changes aren’t incredibly drastic, but they do present great opportunities (and challenges) to those looking to upgrade existing code to the newest version.

Jeremy also has a plugin that became an official Rails plugin that helps guide the developer through the upgrade process.

I know with certainty there are Rails developers concerned up moving existing code to a new Rails, new conventions.  One of Rails strengths are the convention it employs and as developers we learn the intricacies of our framework the hard way.  Rails 3 will require an education to learn the new conventions.

Could this be a point in time where faithful Rails developers move on to a different framework? I doubt devotees won’t, but maybe some.

Active Server Pages

Case in point, Microsoft Active Server Pages.

I have witnessed and been involved with this before when Microsoft created a web framework named Active Server Pages, referred to ASP.  After a much successful growth of ASP developers, Microsoft decided to create ASP.NET which is their current web framework based on webforms.

The problem was that even though the product names were very similar, the truth was they were drastically different.  Developers were faced with:

  • No upgrade path – code written with what we refer to today as “Classic ASP” could not moved to ASP.NET.  It required a complete rewrite since the programming model was different than ASP.
  • Big learning curve – Classic ASP uses a scripting language where there was a single page with logic in the page, ASP.NET moved to a page with a code-behind page in either C# or VB.NET.  The two are very different and someone versed in Classic ASP had to learn everything from the ground up

Developers were faced with making the jump to ASP.NET or deciding to move on to something else, leaving behind the gripes of Microsoft.  Some moved to PHP, as it resembled ASP more than ASP.NET.  Some moved to legacy ASP project to Rails, the views looked more like ASP than ASP.NET

Rails

Up until this point, Rails has been a pretty smooth transition from version to version, even when applications were running older versions of Rails such as 1.2.x and moving to 2.x was pretty straightforward.  I moved many Rails 1.2.6 applications to 2.x and faced little major issues, certainly not a rewrite.

This is not the case when moving to Rails 3, there is no smooth upgrade path and users will be forced to rewrite significant parts of their applications.

The architecture of Rails has changed in a big way, mostly by Yehuda Katz of Merb fame.  Rails 3 takes the good from Merb in many ways, as I would expect.  The view from 50,000’, Rails 3 does not closely resemble Rails 2.x as we know it today.

A Fork in the Road?

As was the case with Classic ASP, I think developers either bit the bullet and rewrote their applications with pain and learning, stayed put and are still there today or moved to a different web framework, maybe Rails, maybe PHP.

I think we are at this point with Ruby on Rails.  Developers are faced with the task of moving to Rails 3 and making that technical leap, not to a new programming language as with ASP.NET, but a new framework.   Rails 3 is different enough from any previous version that moving existing application will not be a rewrite but a change enough to be a considerable effort.  Rails developers are well versed in how the framework functions, Rails 3 is very different.

An Opportunity?

This may be an opportunity for other frameworks to gain some traction.  New developers considering Ruby on Rails 3 have a bigger challenge with the framework, it is not exactly the framework DHH developed only a few years ago.

Other frameworks worth considering:

  • ASP.NET MVC – from Microsoft, allows developers to use C# and VB.NET to create scalable web applications pretty easily.  It also has good community support.
  • Django – a Python-based web framework which has many great features and productivity points.  Django has been around for a few years now and gaining a good amount of traction.
  • Sinatra – a Ruby-based framework with a simple, yet powerful implementation.

I could be wrong here but I think the advantage Rails had with an easy-to-learn framework, great productivity and easy upgrades will be a bit strained in Rails 3.

This will surely be a great opportunity for developers well-versed in Rails 3 to start or expand consulting career helping companies with existing Rails code bases upgrading to Rails 3.  I think these folks will be in high demand.

Conclusion

So what will happen?  I don’t know. Rails is a great framework but converting a large code base is going to be a challenge and Rails 3 is the future, not the 2.3.x code base.

I know I have asked more questions than I have answered.  I hope the powers that be in the Rails leadership understand the concern.

UPDATE: As comments have pointed out, if this sounds Rails-negative, it is not meant to be.  I see this a call for people with knowledge of Rails 3, bits of experience with upgrading projects of any size to share the knowledge.  Blog about what you did, even the most mundane details and share what you know so jump ship DOES NOT happen.

Acts As Conference 2009 Dates and Venue Announced

Posted on October 28, 2008 Written by

aac_badge_xl

The second annual Acts As Conference 2009, a regional Ruby conference, dates and venue has been announced.  The event will take place February 6 & 7, 2009 in Orlando Florida at the Ramada Orlando Celebration Resort & Convention Center, located near all things Disney.  One of the best parts about the event is the cost…only $125.

The venue is different than last year and has the capacity for 175 attendees.  The line-up of talks will include lightening talks as well as more talks than last year.  Robert Dempsey, event organizer, says a call to for papers is coming soon, so get your talk ready.

Keep up with what is going on with this conference on their mailing list.   You can also help spread the word by putting a badge on your web site like the one at the top of this post.

I attended the last acts_as_conference, had a great time and met many people.  I intend on heading down this year as well to enjoy some more mingling and the warm Florida weather after enduring winter here in New England.

Ruby on Rails 2.1 Released at RailsConf

Posted on June 1, 2008 Written by

I was supposed to be at RailsConf this year covering the event for InfoQ, but I am not there.  Sometimes higher priorities overtake the things we would like to do and well, I am home. rails

One of the announcements I thought might be coming at the event was the release of Ruby on Rails 2.1 and sure enough, it was released.   The details are covered on the Riding Rails blog:

Rails 2.1 is now available for general consumption with all the features and fixes we’ve been putting in over the last six months since 2.0. This has been a huge effort by a very wide range of contributors helping to make it happen.

Over the past six months, we’ve had 1,400 contributors creating patches and vetting them. This has resulted in 1,600+ patches. A truly staggering number. And lots of that has made it into this release.

New features
The new major features are:

Thanks to Ryan Daigle for the feature introductions and Ryan Bates for the Railscasts. It makes writing the release notes so much easier :) .

As always, you can install with:

gem install rails

…or you can use the Git tag for 2.1.0.

None of these features actually stand out as the killer feature for this release but is instead a bunch of steady, solid improvements.   Installing the update went without a hitch and my applications on my development system all ran without issue.

Notice the Railscast that accompanies the bulleted points above, they make a nice touch.

Ruby on Rails and the VM of Your Choice

Posted on May 22, 2008 Written by

I think just about everyone in the software development community at least knows what Ruby on Rails is, so I won’t do into it here.   There is some real exciting things going on in the Ruby community and in particular, Ruby on Rails running on more than one implementation of Ruby.  rails

Rails has been running on the original Ruby, Matz’s Ruby Interpreter for a long time now and it runs pretty well.  Recently, other organizations have created new Ruby implementations to compete with the original.

JRuby

JRuby is the first of the new Ruby implementations to successfully get Rails running successfully.   JRuby was an independent open-source project bought by Sun MicroSystems, leveraging the JRuby team and Sun’s knowledge of Java.  JRuby is an implementation of Ruby running on Sun’s Java JVM.

  • A 1.8.6 compatible Ruby interpreter written in 100% pure Java
  • Most builtin Ruby classes provided
  • Support for interacting with and defining java classes from within ruby
  • Bean Scripting Framework (BSF) support
  • Distributed under a tri-license (CPL/GPL/LGPL)

The importance of having a language such as Ruby running with Rails on top of the JVM is really important for the getting Ruby adoption in those organizations heavily invested in Java.  The JRuby team has set a precedent for others to follow, which they have or are close.

Rubinius

Rubinius is a Ruby Virtual Machine written from the ground up from the folks at Engine Yard.  Evan Phoenix is the lead developer for Rubinius.

The Rubinus site details what Rubinius means to developers:

The Rubinius virtual machine is loosely based on the Smalltalk-80 architecture. The small virtual machine is presently implemented in C.

The Ruby core libraries are written in Ruby with some functionality provided by primitives written in C. There is also a foreign function interface (FFI) that enables describing and directly calling functions in system libraries. There is no need to use compiled bindings.

Rubinius has multiple concurrency primitives such as Channels, Actors, Tasks, and Threads. Rubinius is developed in the TDD/BDD style and we are concurrently writing a set of RSpec compatible specs for the Ruby core libraries. Rubinius is also an ideal platform to experiment with various cutting-edge technology like software transactional memory (STM).

The real news about Rubinius is not they are another Ruby interpreter but they recently announced the ability of running Ruby on Rails on Rubinius.  Evan gave the news on his blog:

We hit a major milestone tonight. As most people know, we’ve been working to run Rails on Rubinius by RailsConf to have something to show off, even if it’s pretty slow.

Well, I’m super proud to say that tonight, rails served up both static and dynamic pages under Rubinius. Previous to tonight, we’d been blocked just trying to get Rails to even load. I decided to just try loading it up and bang on it enough to get it up and going.

In a scary way, it didn’t take very much code. Which meant we were very close already.

It’s pretty late, so I’m going to keep this short. Big thanks to everyone who’s contributed to Rubinius and had faith in us. Enormous thanks to Engine Yard, without whom I don’t know if we’d been able to reach this amazing height.

More updates to come…

This is really great news for the Ruby developers, showing there are and will be more options to where and when you can run your Ruby applications.

IronRuby

The last of the Ruby implementations comes from Microsoft with IronRuby.  These project has been in development for quite some time now and takes the folks that made up the RubyCLR project and Ruby.NET projects.  John Lam joined Microsoft as a Project Manager coming with his RubyCLR and Wayne Kelly from the Ruby.NET project is helping the team out.  The team is small within Microsoft but makes up a good number of open source folks who help with the implementation.

Microsoft describes IronRuby as:

IronRuby is a .NET implementation of the Ruby programming language. We are building a high-quality implementation of Ruby, with excellent performance and seamless integration with .NET libraries and infrastructure. We are targeting compatibility with the 1.8.x branch of Ruby modulo continuations.

IronRuby heavily leverages Microsoft’s Dynamic Language Runtime, and both are released with full source code under the Microsoft Permissive License. The IronRuby source code is hosted on Rubyforge, which is a home for open source Ruby projects. We’re looking for contributions to the IronRuby libraries; our goal is to achieve parity with the Ruby standard libraries. If you love .NET and Ruby, then we need your help!

The key part of IronRuby, it runs on the .NET CLR and can take advantage of those large number of existing class libraries and the security of the .NET framework.  This will allow developers to mix their C# and VB.NET code with Ruby take advantage of Ruby’s dynamic features.  Today most Windows servers and desktops have the .NET framework installed, making it an easy to run your Ruby applications.

We undoubtedly can expect great things here with respect to integration to the Dynamic Language Runtime (DLR) and Silverlight, MVC Framework and who knows what else, I don’t think the story here is complete.

As of today the IronRuby team is close to having Ruby on Rails running on the CLR.  I am part of the IronRuby developer list and if I had to guess, I would say by RailsConf 2008 you will see an announcement of Rails running on IronRuby.

Finally

These three alternative implementation of Ruby are really important to the Ruby community.  Each has it strengths and give developers both choice and leverage when trying to move a great dynamic language like Ruby into an organization which may already have a deep investment in Microsoft with .NET or in Sun with Java.  These implementations certainly lower the barrier to entry.

Rubinius comes at Ruby from a different angle creating a Ruby VM written in Ruby.  Why is this important you ask?  It’s important because it opens up the Ruby language to open source developers who may not be skilled in writing C (which is what Matz’s Ruby is written in) but are skilled in Ruby and can help advance the language.  I think most developers miss this point, maybe it is subtle, maybe not, but this is a critical point.

IronRuby has the benefit of being written in C# and developers can help shape that implementation with the abundance of C# developers.

My Interview with Huw Collingbourne up on InfoQ

Posted on April 23, 2008 Written by

I have been a happy Ruby in Steel user for quite a while now and have built a bit of a rapport with Huw Collingbourne, co-founder of SapphireSteel Software, the developers of Ruby in Steel.huw1

On Monday, SapphireSteel Software released a new version of Ruby in Steel, version 1.2.  This version includes a new Visual Rails Workbench that allows developers to create Ruby on Rails applications visually as Visual Studio developers have come to expect.

From the Ruby in Steel web site:

The principal features of the Visual Rails Workbench are:

- Full page editing of complete web pages (composites of Rails layouts/views/partials)
- Drag and Drop design – add controls from a toolbox
- Set properties using the Property panel
- Resize and move controls using mouse or keyboard
- Split view code/form editing
- Toggle ERb/RHTML editing between HTML editor and Rails (Ruby-aware) editor
- Round-tripping between ‘web format’ HTML and ‘Rails format’ ERb/RHTML
- Edit code as ERb/RHTML or as HTML
- Document Navigator navigates document structure (HTML)/or methods (ERB/Ruby)
- Quick navigation between controller and view
- Import/Export to other web page design tools such as Dreamweaver
- Save/restore named ‘versions’ of page designs to/from an archive of work in progress
- Auto-backup of changes to templates
- Support for Rails 1 and Rails 2

The Visual Rails Workbench is one of several significant new additions to Ruby In Steel 1.2.

Other notable features include:

- JRuby Support Users may run and debug Sun’s Java-based JRuby right inside the Ruby In Steel environment.
- IronRuby Support Ruby In Steel is the only IDE to offer integrated form design for Microsoft’s IronRuby (currently ‘alpha’).
- Enhanced Debugging Ruby In Steel has the fastest debugger for standard Ruby. In addition to all its existing capabilities (such as breakpoints, watch variables, call stack navigation, step into/out/over, locals, autos, drill-down debugging and debugging into ERb/RHTML templates)

Ruby In Steel 1.2 adds the following debugging features:

  • Tracepoints
  • Conditional breakpoints

Ruby on Rails and IIS7 Playing Nicely Together

Posted on April 4, 2008 Written by

Ruby on Rails has been around for a few years now and has become a hugely popular web development framework, but not on Windows and Internet Information Server (IIS).  Rails has run on Linux and Max OSX almost exclusively, until recently. 

The Ruby on Rails Wiki has a very good article on setting up Ruby on Rails using IIS7.

Enter FastCGI

FastCGI is the key to getting Rails running in IIS.  The FastCGI web site describes FastCGI as:

FastCGI  is a language independent, scalable, open extension to CGI that provides high performance without the limitations of server specific APIs. See the docs for more details.

Dave Scruggs has a nice short tutorial about his experience getting Rails running on Windows Visata SP1 and IIS 7 with FastCGI.  One of the really nice features of Vista SP1 is that it includes FastCGI built-in. 

In the event you are running IIS7 without FastCGI built in, Dave points out a good tutorial from Carlos Caneja called Install FAST CGI on IIS7.

FastCGI is used to serve applications on IIS7 for languages such as:

  • Ruby
  • Python
  • PHP
  • and others….

What about IIS6?

Most of the recent resources on the web I have seen show FastCGI applications running on IIS7, mainly because it is built-into Vista SP1 and that avoids some configuration difficulties but IIS6 does has FastCGI support for it.  I have not personally attempted it but I may in the future.   The IIS.NET site has some information about using FastCGI on IIS6.

It seems the primary support for FastCGI from Microsoft is on IIS7 but not everyone may be at the point where their web servers are running IIS7 just yet. 

Personal Setup

The tutorials given here are very good and work really well with Vista.  I have a VMWare VM setup on my MacBook Pro running Vista SP1, the setup was flawless.  I have an advantage of many years of IIS experience with a couple years of Ruby on Rails experience, which I think does help.

I would like to see some performance numbers of running Rails or any FastCGI hosted application under IIS.  I am not aware of any but would like to hear back from someone putting IIS and FastCGI through it paces.
