I’ve just written a tutorial on writing plugins that use the Engines  
1.2 plugin. The latest release of Engines changes quite a few things,  
and while they’re all documented in the rdoc, I’ve pulled them  
together into a more easily-digestible format for beginners.

It’s at [http://gwyn.dezyne.net/page/writing\_a\_plugin\_with\_engines\_](http://gwyn.dezyne.net/page/writing_a_plugin_with_engines_) .

I’ve also released a plugin called Macaque, which is a brutally simple  
wiki. It’s at [http://gwyn.dezyne.net/page/macaque](http://gwyn.dezyne.net/page/macaque) .

I’d be interested in feedback on either or both.

Cheers,

Gwyn.

Looks nice Gwyn,

One suggestion though. I’d go for

module Macaque  
mattr\_accessor :option  
self.option = "something’  
end

rather than

@@option = “something”

since it’s better to work with the interface that mattr\_accessor  
guarantees, rather than relying on how it’s implemented 🙂

Hey Gwyn,

It’s useful to have all this information in one place. Thanks!
