== Version 0.12.0 was released on 07/03/2005. A careful blend of new features and subtle improvements to the existing infrastructure. Some important bugs where fixed aswell. Most notable additions: * Nitro allows the definition of metadata for each action. Routing (rewrite) rules, parameter constrains, hierarchy information and custom data can easily be attached to actions: def view @entry = Article[@oid] end action :view, :route => /view\/(.*)/, 'oid' => 1 just browse view/1 and @oid is automatically initialized with request['oid'] Browse the source to see how to add additional constrains, more is comming in the next version. This feature replaces the non portable ParseTree implementation. The scaffolder is updated to generate routings for nice urls. * Og automatically generates finders for all properties, for even easier (and portable) querying: class Article property :title, :body, String property :hits, Fixnum property :create_time, Time end you get the finders: Article.find_by_title Article.find_by_body Article.find_by_hits Article.find_by_create_time The finders take into account the unique constrain, to return an array or just an object as needed. * Og introduces lifecycle observers to avoid 'poluting' the model objects with excess functionality. You can use every object as observer (duck typing) or extend from an AR style Observer class. The observer callbacks are precompiled in the lifecycle methods only if defined, so the perfomance is not affected in the general case. * Factored out templating engine, can now be used in stand-alone mode. Usefull for example to render email templates etc: template = %q{ Hello #{user} dont forget the following facts:
  • #{item}
    • } user = 'gmosx' items = %w{ nitro is really great } out = '' # the rendered template comes here. Template.process(template, :out, binding) * New options in the default runner: --render crawls a web application and renders all pages as static html files. Allows you to leverage Nitro's advanced templating features to generate static sites. --crawl spiders the application, useful for testing. * Better error page, with more information (see blog example). * Fixed Og bug: multiple many_to_many relations with the same target class. * further code cleanup, improved examples and more. == Version 0.11.0 was released on 28/02/2005. The platform continues to evolve and now supports the Apache web server and the Oracle database out of the box. This version features improved documentation, important bug fixes and many subtle improvements to make programming even more enjoyable. Many thanks to Matt Bowen for his help with this release. Most notable additions: * Configuration files for Apache/FastCGI. * Og documentation (doc/og_tutorial.txt, doc/og_config.txt) * Actions with parameters: def list(username, oid) ... end http://www.mysite.com/list?username=tml;oid=2 calls list() with the correct parameters, no need to use request['oid'], just use oid. def list(username, oid) puts oid # oid == request['oid'] end WARNING: this feature requires the ParseTree library which is not compatible with Windows. For the moment, this feature is dissabled by default. To enable this feature, set Nitro.resolve_action_arguments = true. * New session store system, DRb sessions (stored in an independent DRb server) are reimplemented. Session.store_type = :drb * TableBuilder helps in creating html tables. * Integrated builders with the programmatic render. For example:
    #{o.build_table(:id => 'my_tab', :headers => headers, :values => values)
    or

    Object Form #{o.build_form(obj)}

    * Og Oracle adapter. * Og provides advanced metadata for the managed objects class Article property :title, String property :body, String has_many :comments, Comment end par = Article.properties_and_relations => [Property(:title), Property(:body), Og::HasMany(:comments)] par[2].klass => Comment par[2].meta[:linkback] => :article_oid * Og Typemacros, here is an example: def VarChar(size) return String, :sql => "NOT NULL VARCHAR(#{size})" end property :title, VarChar(30) * Option for faster startup, skip schema check. * Many small Og improvements and fixes. * FastCGI adapter bug fixes. * New example, why's wiki, from a cool post at http://redhanded.hobix.com * IMPORTANT security fixes. == Version 0.10.0 was released on 15/02/2005. Another strong release featuring a completely recoded Og implementation and redesigned Og adapter (formely backend) system. An SQLite3 adapter is also provided. Moreover the Nitro installation process is improved, and many small changes make the framework more elegant and easier to use: the updated examples reflect this! Most notable additions: * Improved Og implementation (cleaner code) and new Og adapter subsystem. * New SQLite3 Og adapter, improvements in MySQL and PostgreSQL adapters (WARNING: needs version 1.1.0 of Sqlite3-Ruby). * Added install.rb for easier installation of the tar.gz distribution. * Better GemSpec for easier installation by RubyGems. * Action/template/xsl auto-reloading system in debug mode, new implementation, works again. * New Nitro configuration system, with rational default parameters. * --console option attaches an irb session to a running instace of an application (works again). * Og supports optional typechecking by using property metadata. * request alias for context to be compatible with older versions of nitro and Webrick/jsp and other frameworks. * Improved the examples, cleaner code, work from any directory. * Removed more obsolete code and improved directory structure. * and many more smaller fixes. WARNING: If you used an earlier version of Og you may need to drop your database and let Og recreated it automatically. == Version 0.9.5 was released on 04/02/2005. A bug fix release. * Fixed nasty Windows deadlock bug. * Experimental Wee-style example (will be updated in the next version). * Changed default port to 8069 (8080 was to common). * Small fixes and improvements. == Version 0.9.3 was released on 01/02/2005. A *very* important release. A new abstract rendering pipeline is introduced. This pipeline allows for multiple adaptors (WEBrick, fastcgi are included). Many classes have be rewritten using *clean* code, and the directory structure has improved again. All unused and obsolete files have been removed. A new version of the Blog example was included. This version does not use XSLT and runs on Windows. If you havent seen Nitro or you had problems with an earlier version, this is the time to revisit this project! Most notable additions: * Drastically improved source code readability. * New abstract rendering pipeline. Benefits: * multiple adaptors. * better unit tests. * optimized memory allocation. * more modular desing. * FastCGI support (tested with Lighttpd). * no_xsl_blog example. This new example is easier to setup, even on Windows. This also demonstrates that Nitro does NOT force the use of XSLT. * No global variables used for nitro configuration. * Updated the docs to better reflect the rappidly evolving codebase. * Og metalanguage relations insert metadata into the target class, useful for advanced scaffolders. * Og refer_to meta-language command. * Many bug fixes and small optimizations. The next version will stabilize the Nitro api. == Version 0.8 was released on 12/01/2005. A snapshot of the latest code. Cool new features, many fixes and improvements in older features. Many thanks to Michael Neumann for giving intelligent suggestions and finding small bugs. Most notable additions: * New automatic validation system: class User prop_accessor :name, :password, String validate_confirmation :password validate_length :name, :range => 2..12 end u = User.new(...) unless u.valid? p u.errors.on(:name) p u.errors[:password] end * Programmatic xhtml rendering. This is an alternative method of rendering that is usefull in building components and helpers. This is a preview implementation. options = ['Male', 'Female'] o.select(:name => 'sex') { o.options(options, selected = 1) } options = { 'Male' => 'm', 'Female' => 'f' } o.select(:name => 'sex') { o.options(options, selected = 1) } o.html { o.p(:class => 'header') { o.b('Hello') } } * No global variables in Og. * Recoded Og to allow for future support of multiple databases (even on different RDBMS systems) on a single application. * Improved Blog example demonstrates latest advancements. (You have to drop the database of earlier versions!) * More unit tests. * Supports Ruby 1.8.2 * Integrated extensions/dev-utils by Gavin Sinclair. * Integrated blankslate by Jim Weirich. * And many IMPORTANT bug fixes. == Version 0.7 was released on 27/12/2004. 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! :) == Version 0.6 was released on 13/12/2004. This is a preview release, the api for the new features is not finalized. This early release gives other developers to offer suggestions on the final form of those features. Most notable additions: * Og many_to_many relations with auto generation of the join table. * Og has_one relation. * PHP-style nested output buffering. * Rails-style Filters. * autoreload services. * complile time evaluation of ruby code in templates. * improved pager ui. * initial version of FormBuilder. * initial version of new_app wizard. * Improved Blog example. and... the nitro logo :) == Version 0.5 was released on 23/11/2004. Many new features: * Stand-alone Og distribution. * Scaffolding. * Og RDBMS index support (works again). * improved render/dispatcher. * REST/XML dspatcher. * RssBuilder. * Improved BLOG example. * Many fixes. == Version 0.4.1 was released on 15/11/2004. A MAJOR revision! The rendering engine was recoded from scratch and now features Rails-style actions. Some older features are not yet converted to the new engine though. Other new stuff includes a fully working / cool looking Blog example, a programmable shader pipeline, automatic object manager in Og, improved directory structure, bug fixes, many changes to make it easier to switch from Rails, and many many more cool improvements for you to find out in the detailed ChangeLog. == Version 0.3.0 was released on 01/11/2004. An important revision! Nitro now includes the first version of a brand new ObjectRelational mapping library called Og (ObjectGraph) that combines the best features of Active Record and NDB. A fully working MySQL adapter is also provided. Moreover the code base is further cleaned up. Small improvements to the application configuration system. == Version 0.2.0 was released on 25/10/2004. Greatly improved RDoc documentation. Cleaned up many source files, and improved the directory structure to be more compatible with other Ruby projects. Introduced a test suite. Important bug fixes in NDB. Tiny example no longer requires apache so should run out of the box. == Version 0.1.2 was released on 21/10/2004. The first public version. Features 2 examples and limited documentation. The aim of this release is to make the project known to the Ruby Community. We hope that the Ruby hackers will respond with valueable suggestions and ideas.
