Help Wanted - Chambermaid

Hi folks,

I'm working on a lib called Chambermaid that creates snapshots of ruby
objects and stores them in a git repository.

The main objective of Chambermaid is not to mess with your classes or
objects. Instead Chambermaid should provide a simple but powerful API.

You work with browsers which will give you access to specific diaries
(repos) and diaries which will give you access to specific pages =20
(commits).
These pages contain snapshots of your ruby object.

Still neither documentation nor write support is available. I'm =20
currently
struggling on how to snapshot files.


So here is my question:
__Do you have an idea how I should treat files and other more complex =20=

types?__


P.S.: *Maybe at some point I can Chambermaid keep a diary on =20
herself... :D*

### ./example.rb
     require 'chambermaid'
     require 'person'

     PeopleBrowser =3D Chambermaid.browser Person # =3D> a Browser
     foo_master_page =3D PeopleBrowser[1].last_page # =3D> a Page
     person_foo =3D foo_master_page.target # =3D> a Person

     # method missing binds a Context to the method called returning =20
the value
     # returned by method
     person_foo.id =3D=3D foo_master_page.id


### ./person.rb:
     class Person
       attr_accessor :id, :firstname, :lastname, :email

       # tell Chambermaid where to find the repositories
       Chambermaid.keed_diary self,
           :in =3D> File.join(File.dirname(__FILE__), 'people'),
           :as =3D> :id
     end


### ./people/init.rb
     Chambermaid.ascribe Person do |has|
       # tell chambermaid where attributes should be read from and =20
write to

       # tell Chambermaid that the id is located in 'id.*' which reads
       # the value like:
       #
       # 1. a Context tries to find the correct filename =3D> id.int.1
       # 2. the filename is divided based on '.' =3D> id, int, '1'
       # 3. the last n-1 parts are filters that manipulate the value =20
=3D> int, '1'
       # 4. filters are applied in reverse order =3D> '1', int
       # 5. unrecognized filters, like '1', return itself as value =3D> =20=

'1'
       # 6. the int filter calls to_i on '1' =3D> 1
       # 7. the result is assigned to the attribute id
       has.attribute :id, 'int.%i', :id

       # tell Chambermaid the meta.yml file contains the =20
attributes :firstname and
       # :lastname where .map adds the yml filter chain if not defined.
       has.map :meta do |meta|
         meta.reads(:firstname) { |meta| meta['firstname'] }
         meta.reads(:lastname) { |meta| meta['lastname'] }
       end

       has.attribute :email, 'uri'

     end


### ./people/1/id.int.1
     1


### ./people/1/meta.yml
     ---
     firstname: Foo
     lastname: Bar
     ...


### ./people/1/email.uri
     mailto:[e-mail]
