The Haml team recently announced the release of Haml 1.7, which is an alternative markup system that you can use in Rails, instead of the default ERb-based markup. Version 1.7 is significantly faster than previous releases (and is almost as fast as Rails’ default system, now!). There are a few other new features, too: read all about it in the release notes. Great work!
ActiveReload has just released Warehouse, a simple subversion browser written using Rails. It sports a beautiful UI and can handle the mundane task of user and permission management for you. It’s also being distributed in a unique fashion for most Rails applications. Instead of being hosted, it is sold and downloaded to be installed on your own server.
If you’re interested, check us out at the Warehouse site.
Michel Barbosa has completed his bachelor thesis Delivery of the Key Adoption Factors and Key Characteristics of Companies Using Ruby on Rails. It presents research he has done and conclusions the why and who of switchers.
I’m happy to see that “Joy in Development” was a key adoption factor for 92% of the people interviewed.
Rails to Italy is gathering the Italian Rails community in Pisa from October 26th through 27th. They’re open for registration and are still looking for speakers. The price to participate is €89 for registrations done before August 1st.
Zilia Iskoujina is a PhD student from the UK who’s doing research on Knowledge management and innovation in virtual organisations. As part of that, a questionaire for people working in open source has been created. If you have 15 minutes, consider filling it out.
A million yen ($8,300) is the first price for a new application competition called Award on Rails that starts tomorrow. The competition is sponsored by DRECOM and will run from July 2nd until September 25th. While the show is based in Japan, they’ll be accepting entries from all over the world. Read all about the rules and the sponsors or sign up to participate. Good luck!
I am such a chicken. I very much wanted the next release of Capistrano to be the official “Capistrano 2.0” release. But as I watched the changelog grow, I started to get cold feet.
Thus, tonight I announce the fourth (and final, hopefully!) preview release of Capistrano 2.0. As before, you can grab it from the Rails beta gems server:
gem install -s http://gems.rubyonrails.com capistrano
(What is Capistrano, you ask? Allow me to direct your attention to http://www.capify.org…)
The following items are just some of the changes new in preview #4:
- The deploy:symlink task works correctly now when run by itself.
- Synchronously instantiate the gateway to prevent it being instantiated multiple times.
- Use “which” instead of "test -p to test whether a command exists on the path.
- The :hosts and :roles keys can now accept lambdas, to lazily select which hosts or roles a task uses.
- Versions of Net::SSH prior to 1.1.0 work with Capistrano again.
- Variable accesses are now thread safe.
- The deployment code is now locale-independent, so that the revision is parsed correctly even if your computer is using a non-English locale.
- You can now pass :on_error => :continue when defining a task, so that any connection or command errors that occur during the task’s execution will be ignored, allowing the task (and subsequent tasks) to continue.
You can see the entire list of changes in the CHANGELOG.
So, give it a go. Try it out. Post your feedback to the Capistrano mailing list. I’d love to release cap2 final next week!
P.S. If you are on a Windows machine, and you get Zlib errors trying to install the Capistrano gem, try this. Find the rubygems/package.rb file (wherever it happens to be in your Ruby installation), open it up, and find the zipped_stream method. Then, replace it, wholesale, with the following:
def zipped_stream(entry) entry.read(10) # skip the gzip header zis = Zlib::Inflate.new(-Zlib::MAX_WBITS) is = StringIO.new(zis.inflate(entry.read)) ensure zis.finish if zis end
That seems to do the trick for me; let me know if it doesn’t work for you.
The Berlin Ruby User Group is throwing a pre-RailsConf party under the banner of Bratwurst on Rails.
The Ruby User Group Berlin is one of the biggest in Germany and therefore we’re pleased to organize an event on the night before the RailsConf Europe. In the tradition of last year’s “Pizza on Rails” the event is called “Bratwurst On Rails.”
The event is an opportunity to socialize and meet the conference participants in a relaxed atmosphere, and to make your name or brand known amongst them. Tighten your knots with the community by becoming a sponsor.
The venue will be in the heart of Berlin, close to the conference venue. Entry will be free, as will the food. (If you’re interested in sponsoring, have a look at our sponsoring packages and feel free to contact the organisation board via firstname.lastname@example.org).
Alright, we’re nearing the finish line! Capistrano 2.0 Preview Release #3 is now available.
Capistrano is a utility for automating the execution of tasks on one or more remote machines. You can read all about it at www.capify.org.
To install Preview #3, you’ll need to grab it from the Rails beta gem server:
gem install -s http://gems.rubyonrails.org capistrano
Accompanying PR3 is a new page of documentation on the capify.org site: Capistrano Basics. This walks you through the major features of Capistrano, but does not touch on deployment. This makes it a great introduction for those wanting to use Capistrano in non-deployment scenarios.
Preview #3 includes the following changes and enchancements:
Feature: Mercurial and CVS are now supported out of the box. Just set your :scm variable to :mercurial or :cvs, like so:
set :scm, :mercurial # or set :scm, :cvs
Thanks to Tobias Luetke and Matthew Elder for the Mercurial module, and Brian Phillips for the CVS module.
Feature: There is now a :default_environment variable, which is a hash that can be used to set environment variables that should be present for all commands that are executed. For instance:
default_environment["PATH"] = "/bin:/usr/bin:/usr/local/bin:/home/jamis/bin"
Feature: All commands are now explicitly invoked via “sh”, which means that even if your default user shell is non-POSIX (e.g., tcsh, csh, etc.), you can use Capistrano just fine. Note that if you were using tcsh or csh syntax in your Capistrano scripts, you now need to set the :default_shell variable to use your (non-POSIX) shell of choice:
set :default_shell, "/usr/bin/tcsh"
Feature: You can declare empty roles, and Capistrano won’t complain. This is useful for predeclaring roles that need to exist (because task definitions depend on them), but which might not have any servers in them (depending on runtime conditions).
Feature: A username and port specified with the server definition (e.g., “email@example.com:1234”) now take precedence over the :username and :port settings in the ssh_options hash, rather than the other way around. This lets you set a general default via ssh_options, and override on a per-server basis in the server definitions themselves.
There are several other minor changes and fixes as well; you can read the CHANGELOG for all the gory details.
The hackfest is back! In sleek new form, the ’fest runs monthly, starting now.
Without further ado: it’s on. Two weeks to go. Sprint!
Thanks to Working With Rails for making this an integral part of their site; thanks to O’Reilly for signing on as the first sponsor (first prize is a free pass to RailsConf Europe); and thanks to you for contributing the patches and bugfixes that keep Rails at the top of its game.
