Upgraded to Rails 2.0.2, except that we maintain vendor/rails/actionpack/lib/action_controller/routing.rb from Rail 1.2.6 (at least for now), so that Routes don't change. We still get to enjoy Rails's many new features. Also fixed a bug in Chunk-handling: disable WikiWord processing in tags (for real this time).

module Hash #:nodoc:

# Allows for reverse merging where its the keys in the calling hash that wins over those in the <tt>other_hash</tt>.
|
|
# This is particularly useful for initializing an incoming option hash with default values:
|
|
#
|
|
# def setup(options = {})
|
|
# options.reverse_merge! :size => 25, :velocity => 10
|
|
# end
|
|
#
|
|
# The default :size and :velocity is only set if the +options+ passed in doesn't already have those keys set.
