EDGE

• Samuel Williams (www.oriontransfer.co.nz/):

        Thanks to Tekin for his patches.
        Updated migrations system to tie in more closely with the current rails mechanism.
        Rake task for updating database schema info
                rake db:migrate:upgrade_plugin_migrations
        Please see http://engines.lighthouseapp.com/projects/10178-engines-plugin/tickets/17 for more information.
  

• Refactored the view loading to work with changes in Edge Rails
• Fixed integration of plugin migrations with the new, default timestamped migrations in Edge Rails
• Refactored tests into the plugin itself - the plugin can now generate its own test_app harness and run tests within it.

2.0.0 - (ANOTHER) MASSIVE INTERNAL REFACTORING

• Engines now conforms to the new plugin loading mechanism, delegating plugin load order and lots of other things to Rails itself.

1.2.2

• Added the ability to code mix different types of files, cleaning up the existing code-mixing implementation slightly (Ticket 271)

1.2.1

• Added documentation to clarify some of the issues with Rails unloading classes that aren‘t required using "require_dependency" (Ticket 266)
• Fixed a bug where test_help was being loaded when it wasn‘t needed, and was actually causing problems (Ticket 265)

1.2.0 - MASSIVE INTERNAL REFACTORING

• !!!Support for Rails < 1.2 has been dropped!!!; if you are using Rails =< 1.1.6, please use Engines 1.1.6, available from svn.rails-engines.org/engines/tags/rel_1.1.6
• Engines are dead! Long live plugins! There is now no meaningful notion of an engine - all plugins can take advantage of the more powerful features that the engines plugin provides by including app directories, etc.
• Init_engine.rb is no longer used; please use the plugin-standard init.rb instead.
• Engines.start is no longer required; please use the config.plugins array provided by Rails instead
• To get the most benefit from Engines, set config.plugins to ["engines", "*"] to load the engines plugin first, and then all other plugins in their normal order after.
• Access all loaded plugins via the new Rails.plugins array, and by name using Rails.plugins[:plugin_name].
• Access plugin metadata loaded automatically from about.yml: Rails.plugins[:name].about. Plugin#version is provided directly, for easy access.
• Module.config is has been removed - use mattr_accessor instead, and initialize your default values via the init.rb mechanism.
• Public asset helpers have been rewritten; instead of engine_stylesheet, now use stylesheet_link_tag :name, :plugin => "plugin_name"
• Plugin migrations have been reworked to integrate into the main migration stream. Please run script/generate plugin_migration to create plugin migrations in your main application.
• The fixture method for loading fixtures against any class has been removed; instead, engines will now provide a mechanism for loading fixtures from all plugins, by mirroring fixtures into a common location.
• All references to engines have been removed; For example, any rake tasks which applied to engines now apply to all plugins. The default Rails rake tasks for plugins are overridden where necessary.
• Layouts can now be shared via plugins - inspiration gratefully taken from PluginAWeek‘s plugin_routing :)
• Actual routing from plugins is now possible, by including routes.rb in your plugin directory and using the from_plugin method in config/routes.rb (Ticket 182)
• Controllers are no longer loaded twice if they‘re not present in the normal app/ directory (Ticket 177)
• The preferred location for javascripts/stylesheets/etc is now ‘assets’ rather than ‘public‘
• Ensure that plugins started before routing have their controllers appropriately added to config.controller_paths (Ticket 258)
• Removed Engines.version - it‘s not longer relevant, now we‘re loading version information from about.yml files.
• Added a huge amount of documentation to all new modules.
• Added new warning message if installation of engines 1.2.x is attempted in a Rails 1.1.x application
• Added details of the removal of the config method to UPGRADING
• Removed the plugins:info rake task in favour of adding information to script/about via the Rails::Info module (Ticket 261)
• Improved handling of testing and documentation tasks for plugins

1.1.4

• Fixed creation of multipart emails (Ticket 190)
• Added a temporary fix to the code-mixing issue. In your engine‘s test/test_helper.rb, please add the following lines:

   # Ensure that the code mixing and view loading from the application is disabled
   Engines.disable_app_views_loading = true
   Engines.disable_app_code_mixing = true
  

  which will prevent code mixing for controllers and helpers, and loading views from the application. One thing to remember is to load any controllers/helpers using ‘require_or_load’ in your tests, to ensure that the engine behaviour is respected (Ticket 135)

• Added tasks to easily test engines individually (Ticket 120)
• Fixture extensions will now fail with an exception if the corresponding class cannot be loaded (Ticket 138)
• Patch for new routing/controller loading in Rails 1.1.6. The routing code is now replaced with the contents of config.controller_paths, along with controller paths from any started engines (Ticket 196)
• Rails’ Configuration instance is now stored, and available from all engines and plugins.

1.1.3

• Fixed README to show ‘models’ rather than ‘model’ class (Ticket 167)
• Fixed dependency loading to work with Rails 1.1.4 (Ticket 180)

1.1.2

• Added better fix to version checking (Ticket 130, jdell@gbdev.com).
• Fixed generated init_engine.rb so that VERSION module doesn‘t cause probems (Ticket 131, japgolly@gmail.com)
• Fixed error with Rails 1.0 when trying to ignore the engine_schema_info table (Ticket 132, snowblink@gmail.com)
• Re-added old style rake tasks (Ticket 133)
• No longer adding all subdirectories of <engine>/app or <engine>/lib, as this can cause issues when files are grouped in modules (Ticket 149, kasatani@gmail.com)
• Fixed engine precidence ordering for Rails 1.1 (Ticket 146)
• Added new Engines.each method to assist in processing the engines in the desired order (Ticket 146)
• Fixed annoying error message at appears when starting the console in development mode (Ticket 134)
• Engines is now super-careful about loading the correct version of Rails from vendor (Ticket 154)

1.1.1

• Fixed migration rake task failing when given a specific version (Ticket 115)
• Added new rake task "test:engines" which will test engines (and other plugins) but ensure that the test database is cloned from development beforehand (Ticket 125)
• Fixed issue where ‘engine_schema_info’ table was included in schema dumps (Ticket 87)
• Fixed multi-part emails (Ticket 121)
• Added an ‘install.rb’ file to new engines created by the bundled generator, which installs the engines plugin automatically if it doesn‘t already exist (Ticket 122)
• Added a default VERSION module to generated engines (Ticket 123)
• Refactored copying of engine‘s public files to a method of an Engine instance. You can now call Engines.get(:engine_name).copy_public_files (Ticket 108)
• Changed engine generator templates from .rb files to .erb files (Ticket 106)
• Fixed the test_helper.erb file to use the correct testing extensions and not load any schema - the schema will be cloned automatically via rake test:engines
• Fixed problem when running with Rails 1.1.1 where version wasn‘t determined correctly (Ticket 129)
• Fixed bug preventing engines from loading when both Rails 1.1.0 and 1.1.1 gems are installed and in use.
• Updated version (d‘oh!)

1.1.0

• Improved regexp matching for Rails 1.0 engines with peculiar paths
• Engine instance objects can be accessed via Engines[:name], an alias for Engines.get(:name) (Ticket 99)
• init_engine.rb is now processed as the final step in the Engine.start process, so it can access files within the lib directory, which is now in the $LOAD_PATH at that point. (Ticket 99)
• Clarified MIT license (Ticket 98)
• Updated Rake tasks to integrate smoothly with Rails 1.1 namespaces
• Changed the version to "1.1.0 (svn)"
• Added more information about using the plugin with Edge Rails to the README
• moved extensions into lib/engines/ directory to enable use of Engines module in extension code.
• Added conditional require_or_load method which attempts to detect the current Rails version. To use the Edge Rails version of the loading mechanism, add the line:
• Engines.config :edge, true
• to your environment.rb file.
• Merged changes from /branches/edge and /branches/rb_1.0 into /trunk
• engine_schema_info now respects the prefix/suffixes set for ActiveRecord::Base (Ticket 67)
• added ActiveRecord::Base.wrapped_table_name(name) method to assist in determining the correct table name

1.0.6

• Added ability to determine version information for engines: rake engine_info
• Added a custom logger for the Engines module, to stop pollution of the Rails logs.
• Added some more tests (in particular, see rails_engines/applications/engines_test).
• Another attempt at solving Ticket 53 - controllers and helpers should now be loadable from modules, and if a full path (including RAILS_ROOT/ENGINES_ROOT) is given, it should be safely stripped from the require filename such that corresponding files can be located in any active engines. In other words, controller/helper overloading should now completely work, even if the controllers/helpers are in modules.
• Added (finally) patch from Ticket 22 - ActionMailer helpers should now load
• Removed support for Engines.start :engine, :engine_name => ‘whatever’. It was pointless.
• Fixed engine name referencing; engine_stylesheet/engine_javascript can now happily use shorthand engine names (i.e. :test == :test_engine) (Ticket 45)
• Fixed minor documentation error (‘Engine.start’ ==> ‘Engines.start’) (Ticket 57)
• Fixed double inclusion of RAILS_ROOT in engine_migrate rake task (Ticket 61)
• Added ability to force config values even if given as a hash (Ticket 62)

1.0.5

• Fixed bug stopping fixtures from loading with PostgreSQL

1.0.4

• Another attempt at loading controllers within modules (Ticket 56)

1.0.3

• Fixed serious dependency bug stopping controllers being loaded (Ticket 56)

1.0.2

• Fixed bug with overloading controllers in modules from /app directory
• Fixed exception thrown when public files couldn‘t be created; exception is now logged (Ticket 52)
• Fixed problem with generated test_helper.rb file via File.expand_path (Ticket 50)

1.0.1

• Added engine generator for creation of new engines
• Fixed ‘Engine’ typo in README
• Fixed bug in fixtures extensions
• Fixed /lib path management bug
• Added method to determine public directory location from Engine object
• Fixed bug in the error message in get_engine_dir()
• Added proper component loading
• Added preliminary tests for the config() methods module

pre-v170

• Fixed copyright notices to point to DHH, rather than me.
• Moved extension require statements into lib/engines.rb, so the will be loaded if another module/file calls require ‘engines
• Added a CHANGELOG file (this file)
