Meta Bates

It is with a sad and heavy heart that this evening I announce that I will no longer be developing the Mack Framework. The project, started a year ago, and has been source of great pride, joy, and at times frustation. Of all the projects I have ever worked on, this one was definitely closest to my heart.

The decision to stop working on Mack was something I did not take lightly. If I had my druthers, and plenty of free time and a source of funding, I most certainly would continue on working on it. However, reality has a different way of plenty out.

When I first started developing Mack the company I was working for at the time was frustrated with the pains and shortcomings of Rails. It was the right platform for the company when we started, however, two years in a start up is a life time and the company took many twists and turns, that lead us to the path of seeking an alternative platform to Rails. At the time Merb was not a serious contender, and there was little else out there that was looking to satisfy the needs we had. Enter Mack. I spent nearly 10 months developing Mack for that company. We rolled out several Mack applications. It worked really well for what we wanted it to do.

Again, however, reality came into play. The company was forced to lay off nearly 50% of its staff, and I was one of them. I quickly took a position as the Director of Engineering for another startup in Boston. This shop, too, is a Rails shop. The difference between the two companies is that for the company I work for now Rails is the right solution. This means that I am spending my days working with Rails, and not developing Mack.

At night and on the weekends I like to spend time with my wife and my son. I play in a band, www.thebluewires.com, and I am working on a book for Addison-Wesley entitled, “Distributed Programming with Ruby”. I’m a busy man, and Mack is a big project. You can’t successfully write a web framework part time. Especially when that part time is really more like part-part time. You need to be able to put dedicated full time resources onto a project of that scale, and I just don’t have the time to do it.

Would I love to see the project continue? Certainly. If there is someone out there who wants to take it on, please let me know. I would love to see it grow. There is so much I wanted to do with it. So many great ideas.

Now, for the good news, I am planning to port a bunch of the Mack functionality over to the Rails 3 platform. The obvious one being the mack-distributed package which is a key differentiator between Mack and the other Ruby frameworks. Another package I think worthy of migration is mack-notifier, which provides, in my opinion, a really nice clean API for doing notifications, whether they be email, Jabber, SMS, etc… I also really like the mack-data_factory package. It provides an ORM agnostic way to do great data factories for testing. Finally there are some routing improvements that I think Rails could really benefit from, as well as a few other bits and bobs here and there.

I wish to thank everyone who has supported this project over the year. A few key people I think that deserve a special call out are: Darsono Sutedja (the second biggest contributed to Mack), Gerardo Pis-Lopez (the third biggest contributor), and Greg Arsenault (my previous boss who fought for me to develop Mack). If there was such a thing as the Mack Core Team, those guys would be it. I would also like to thank people like Peter Cooper, Gregg Pollack, Adam French, Dan Kubb, and everyone else who either opened a Lighthouse ticket, submitted a patch, wrote a blog entry about Mack, or who was just there for support and guidance over the past year.

I am going to keep www.mackframework.com around as a forum for my other projects, such as Cachetastic and Configatron, and the other projects I have brewing. Expect some cool new projects out of me in 2009, include some iPhone projects that I’m excited about undertaking. I will be releasing the last version of Mack by the end of the month. It will essentially be a few bug fixes, an upgrade of DataMapper, and Sass support.

To summarize, thank you everyone. I appreciate your support and I look forward to contributing to the community in new and exciting ways.

Thank you.

Hey there folks, sorry for the long wait for this release, but it’s here. It’s been a long November for yours truly. I’ve had to find a new job. I’ve had pneumonia. We, at least in America, have celebrated Thanksgiving. And, of course, who can forget RubyConf 2008?

So with that said, what’s in 0.8.2? Honestly, not a whole lot. There are a couple of bug fixes, a button_to_remote (think submit_to_remote in Rails) helper, and deferred routes. More on deferred routes in a moment, as it’s actually a pretty cool feature that only Mack and Merb share. And finally there is bundled gems.

Bundled Gems

What do I mean I say ‘bundled gems’? Well, because of the rather large number of gems that get installed with Mack, and because of some gem version dependency issues, Mack is now bundling it’s third party dependency gems inside itself. For example, mack-facets used to rely on the gems ‘facets’ and ‘english’. Those gems are now bundled inside the mack-facets gem and now longer need to be downloaded and installed by end users. This should make installing Mack super easy. It should also make dealing with having multiple versions of Mack installed on your system easier to deal with and maintain.

Deferred? Routes

So what are deferred routes? Ezra wrote a really great write up back in April. The idea is simple, with newer web servers such as Thin and Ebb, you can tell them to spawn a new thread to handle particular requests, such as long running processes like file uploads. This can really help speed things up as server can process regular requests using an event machine model, which is very fast, but can be really slow and block the server for longer processes. Now those processes can spawn into their own threads and not block the server.

In Mack 0.8.2 you can mark your routes with a deferred? => true option which will trigger this behavior. It’s much more advanced than the similar feature that can be found in Merb, which requires a separate configuration for your deferred actions, and the urls have to be ‘hard coded’. Mack let’s you use all the dynamic power of your routes, like you would want to. It’s just another option on the route itself. For a great tutorial on using deferred routes, check out the following page on www.mackery.com:

I know with each release I say how excited I am by this release, but that’s usually because with each release there’s some great new feature that makes me either proud to have developed it, or to proud to be associated with it. Mack 0.8.1 is definitely no exception.

Before I get into what has to be my favorite feature since the distributed features of 0.7.0, and quite possibly my favorite feature in Mack today, let’s talk about a few of the other features in this release.

More Routing Enhancements

There are a few great new features in the routing system in this release. The first off is a real crowd favorite, Nested Resources. Just like Rails you can now nest resources in Mack.

http://www.mackery.com/routing/nested_resources

In Mack 0.8.0 we introduced the ability to put host information in the routes file. This would be used to match the host when matching a route as well as building the url for that route when using the url helpers. This made dealing with subdomains very easier. Well, to really give everyone that subdomain fu everybody loves, we’ve added the ability to put embedded parameters in the host parameter in routes. It’s pretty dang cool, let me tell you. Checkout these examples:

http://www.mackery.com/routing/misc

Pagination API

There is now a pagination API that’s part of the mack-orm API. The first implementation of this in the mack-data_mapper package. At its heart it’s extremely easily to implement for new ORMs, one method, and using it is just as easy. There will be a write up on using the API in the forth coming days.

Jabber Support

The mack-notifier package can now send notifications using the Jabber protocol.

!!Portlets!!

Portlets are what components in Rails should’ve been and they’re what slices in Merb should be. Portlets are a way off packaging a full Mack application into a Ruby Gem so they can easily be shared and used in other Mack applications. As you’re about to see, this simple page is all the information you need to know about developing, testing, packaging, and using Portlets.

Portlets encapsulate a whole Mack application, from controllers to views to models to configuration settings to your images, stylesheets and javascripts. This makes it possible to develop extremely rich applications and share them with other Mack applications.

Mack 0.6.1.1 features 38 completed tickets and a whole host of really great features and improvements. Here’s a quick overview of a few of the big features in Mack 0.6.1.1.

Page Caching

There is now a mack-caching gem which gives you easy to use page caching when you require it. To use page caching first you need to add it to your gems.rb file like such:

gem.add "mack-caching", :libs => "mack-caching"

That will require the gem and give your app access to the page caching libraries. Next you to turn on page caching in your application. In the appropriate config/*.yml file add the following:

use_page_caching: true

Now, you just need to tell your controllers which actions they should cache:

class FooController
  include Mack::Controller
  cache_pages  nly => [:index, :show]
end

If you give the cache_pages no optional parameters then it will cache all the actions for that controller. Alternatively, you could give it an :except parameter to list the actions you don’t want cached. 

Notifiers (aka Mailers)

Mack now has a mack-notifier gem that will be the repository for all ‘notification’ systems, the first of which is email. The Mack::Notifier API is simple and easy to use and will allow developers to plugin in different notification systems under the cover without having to change their application code. 

A notifier can look as simple as:

class WelcomeEmail
  include Mack::Notifier
end

With that you can then write the following bit of code:

we = WelcomeEmail.new
we.to = "foo@example.com"
we.from = "bar@example.com"
we.subject = "Hello World"
we.body(:text) = "My plain text body"
we.body(:html) = "My html body"
we.attach(Mack::Notifier::Attachment.new("/path/to/my/file")) 
we.deliver

Obviously there’s a lot more to the API, including a validations module, but that’s a subject for another post. 

JavaScript (aka RJS)

The mack-javascript gem now gives you Rails-like RJS support for Mack. The default library to use with mack-javascript is jQuery, but there is prototype support available as well. 

Data Factory

Creating faux data for testing can be a real nightmare. Fixtures can be difficult to maintain and trying to create your own faux data can be a chore. That’s where the mack-data_factory gem comes in.

For each model that you want to produce, you will need to define a factory class.  

Let’s say that I have 2 models: Item and User, and Item belongs to user.  So the factories will look like the following:

class ItemFactory
  include Mack::Data::Factory
  field :title, "MyItem"
  field  wner_id, {:user => 'id'}
end

class UserFactory
  include Mack::Data::Factory
  field :username, "planters", :length => 25, :content => :alpha
  field :password, "roastedPeanuts", :immutable => true
end

So, the 2 classes above defined the factory for item and user.  As you can see, each factory will need to explicitly list all the fields that it will populate, and for each field, you can define rules on how the content is generated.

Supported content types: 

• :alpha –> alphabets.  rules: [:length, :min_length, :max_length]
• :alphanumeric –> alphabets and number.  rules: same as :alpha
• :numeric –> numbers [optional, because if the field's default value is number, its content type will automatically set to numeric)
• :email --> generate random email address
• :username --> generate random username
• :domain --> generate random domain name
• :firstname --> generate first name
• :lastname --> generate last name
• :name --> generate full name
• :city --> generate city name
• :streetname --> generate street name
• :state --> generate state.  rules: [:country --> :us or :uk, :abbr --> true if you want a abbreviated state name (us only)]
• :zipcode –> generate zipcode. rules: [:country --> :us or :uk]
• :phone –> generate phone number
• :company –> generate company name.  rules: [:include_bs --> include sales tag line]
  example:  field, “”, :content => :company, :include_bs => true could generate something like:
