Subject: [ANN] Nitro 0.7.0 + Og 0.7.0

Hello everyone,

a new version of Nitro was just released.

Homepage: http://www.navel.gr/nitro
Download: http://www.rubyforge.com/projects/nitro

A snapshot of the latest code. Many fixes and new features result
in a more mature product. Many thanks to the ruby hackers that sent
suggestions and patches used in this release!

Most notable additions:

* Improved win32 compatibility (Tiny example runs out of the box).
* Binary content example (Flash, needs ruby-ming installed to run).
* Totaly recoded prop_accessor mechanism, avoids polution of the Module
class.
* prop_accessors for Modules, allows synthesizing of managed objects
from Mixins.
* new automatically generated methods in Og.
* MockDatabase leverages the FlexMock object for easier unit testing.
* Integrated the cool Breakpointer library by Florian Gross.
* Markup mixin to automatically expand/compact generalized markup code.
* new_form wizard.
* Statically (compile time) included subscripts.
* Important bug fix in redirects.

and many many bugfixes! :)some words about Nitro:

Nitro is an efficient, yet simple engine for developing
professional Web Applications using the Ruby language.
Nitro aims to provide a robust infrastructure for scalable
web applications that can be distributed over a server cluster.
However, Nitro can also power simple web applications for
deployment on intranets or even personal computers.

Nitro integrates the Og (ObjectGraph) object-relational mapping
library. Og provides transparent serialization of object graphs to a
RDBMS backend. Unlike other similar libraries Og maps standard Ruby
objects to SQL tables and not vice versa. Og provides a meta language
to describe the relations between objects, a flexible and intuitive api
for querieng the database, raw access to the SQL language if needed
(for example to fine tune the automatically generated SQL tables, or
for custom queries), suports deserialization to Ruby objects or tuples,
automatically generates join tables for many_to_many relations
and provides a collection of usefull Mixins to synthesize common
Entities.

Og is a combination of the best features of Active Record and the
former O-R mapping library included in Nitro (NDB). Adapters for
PostgreSQL and MySQL are included.


Suggestions, ideas, bug reports are welcome!
have fun,
George Moschovitis
