Exc
===

You can use exc to create many multi-channel error/log/message handlers.

Currently 4 processors are available:


:console
(turn on by passing ':console => true')



:rails_log
(turn on by passing ':rails_log => true')



:global_flash
(turn on by passing 'global_flash => true')
Place following or similar code to application controller to use it

...
 after_filter :show_errors
 def show_errors
    flash[:warn] = Err.message if Err.errors?
  end
...



:custom_logger
Usage:
SR_LOGGER = Logger.new(File.join(RAILS_ROOT,'log','system.log'))
Log = ErrorMessageHandler.new( :custom_log => [SR_LOGGER])



Example (general usage)
===================================

>> AppError = ErrorMessageHandler.new(:console => true, :rails_log => true, :global_flash => true)
=> AppError

>> AppError.errors?
=> false

>> AppError.new('Normal error message...')
Normal error message...
=> #<AppError:0x6164f58>

>> AppError.new('Persistant error message...', :persistant => true)
Persistant error message...
=> #<AppError:0x616163c>

>> AppError.errors?
=> true

>> AppError.message
=> "<li>Normal error message...</li><li>Persistant error message...</li>"

>> AppError.message
=> "<li>Persistant error message...</li>"

>> AppError.new(Exception.new("New error from exception"))
New error from exception
=> #<AppError:0x615aa6c>

>> AppError.new(Exception.new("New persistant error from exception"), :persistant => true)
New persistant error from exception
=> #<AppError:0x6155b98>

>> AppError.errors?
=> true

>> AppError.errors
=> [#<struct Exc message="Persistant error message...", persistant=true, obj=nil>, #<struct Exc message="New error from exception", persistant=nil, obj=#<Exception: New error from exception>>, #<struct Exc message="New persistant error from exception", persistant=true, obj=#<Exception: New persistant error from exception>>]

>> AppError.message
=> "<li>Persistant error message...</li><li>New error from exception</li><li>New persistant error from exception</li>"

>> AppError.message
=> "<li>Persistant error message...</li><li>New persistant error from exception</li>"

>> AppError.purge_errors!
=> []

>> AppError.message
=> ""


Example (remote execution)
===================================

require 'activeresource'

class Exc  < ActiveResource::Base
    self.site = "http://localhost:3000"
end

Exc.create(:klass => "Log", :message => "nice!!!")
