xamplr

xamplr is a set of software tools that supports development of ruby applications.

Features:

- supports Domain Driven Design in Ruby
- persistence ignornace
- clusters, entities, 'regular' objects, and repositories (corresponding approximately to DDD's aggregates, entities, value objects, and repositories)
- different peristence techniques including filesystem (XML format) and Tokyo Cabinet
- transaction support
- querying 
- fast development, fast execution
- has been in use in commercial software since 2004, a Java version has been in use since 1998.

Anti-Features:

- absymal lack of documentation. If you are brave and willing to wade through (old) blog entries, you might try looking at:

Installation:

The stable release is hosted on rubyforge as a gem, so:

    [sudo] gem install xamplr

The most recent release is hosted on github, also as a gem, so:

    gem sources -a http://gems.github.com
    [sudo] gem install hutch-xamplr

The most recent code is in the repository, so clone the github project and either
use it directly (with a little fooling about with load paths), or build it as a gem
and install locally.

License:

For the moment it is AGPLv3 (see COPYING). An alternative license may be negotiated, contact me. In the near future this license will be relaxed.
