Multi-app functionality is now officially supported in Merb using Slices.
Multi-app functionality is now officially supported in Merb using merb-slices – from the README:
Merb-slices
Merb-Slices is a Merb plugin which forms the basis for using and creating application ‘slices’ which help you modularize your application. Usually these are reuseable extractions from your main app. In effect, a Slice is just like a regular Merb MVC application, both in functionality as well as in structure.
When you generate a Slice stub structure, a module is setup to serve as a namespace for your controller, models, helpers etc. This ensures maximum encapsulation. You could say a Slice is a mixture between a Merb plugin (a Gem) and a Merb application, reaping the benefits of both.
A host application can ‘mount’ a Slice inside the router, which means you have full over control how it integrates. By default a Slice’s routes are prefixed by its name (a router :namespace), but you can easily provide your own prefix or leave it out, mounting it at the root of your url-schema. You can even mount a Slice multiple times and give extra parameters to customize an instance’s behaviour.
A Slice’s Application controller inherits from Merb::Slices::Controller, which in turn inherits from Merb::Controller. This isn’t strictly necessary to work, but it gives you specific view-handling functionality.
There are many ways which let you customize a Slice’s functionality and appearance without ever touching the Gem-level code itself. It’s not only easy to add template/layout overrides, you can also add/modify controllers, models and other runtime code from within the host application.
To create your own Slice run this (somewhere outside of your merb app):
$ merb-gen slice your-lowercase-slice-name

Multi-app functionality is not (yet?) officially supported in Merb. However, there is definitely interest in exploring possibilities to facilitate the feature.

It follows the concepts discussed in the post below quite closely.

Expect to find more info here as we uncover Merb’s multi-app capacity.
