Welcome in many languages (in JSON format)

Today I wanted to implement a multi-language greeter for an application, and I ended up on http://www.omniglot.com/language/phrases/welcome.htm

I extracted all the welcomes from the page using jQuery, serialized them as JSON and processed them using Ruby:

welcomes = x.inject({}) {|h, (lang, val)| val.gsub!(/(.?)/, ''); vals = val.split(%r{\s+/\s+|\n}); vals.map! {|val| val.strip!; val.gsub!(/^\w+ -\s+|- \w+$|^lit.|>.+$/, ''); val.strip!; val}; vals.flatten!; vals.reject!(&:blank?);; h.update(lang => vals) }

Boolean/Mathematical Expressions Parser, built with the *excellent* Dhaka language
generation library, available on http://dhaka.rubyforge.org/.

Have a look at the extensive test suite for insights on how to use this software,
especially the protected methods in `test/boolean_expression_parser_test.rb`.

The software is licensed under the same terms as Ruby.

COPY FROM STDIN / LOAD DATA INFILE method for Rails PostgreSQL and MySQL Adapters.
The mysql adapter is completely untested. It is self-explanatory, isn't it? :)

A simple class decorator. Useful when implementing some sorts of the evil twin pattern.

It works by creating a blank class slate (with Class.new), removing on it EVERY
method, except `__id__`, `__send__` and `initialize`. It then defines the `class`
method to return the original class, and implements both an `initialize` and a
`method_missing`.

The `initialize` sends the `new` method to the original class, therefore creating
a new instance of the original class and saves it in the @_object instance variable.

# * find_by_XYZ     -> calls the `XYZ` method on the array items,
#                      returing the first one on which the method
#                      didn't return nil/false
# * find_all_by_XYZ -> calls the `XYZ` method on the array items,
#                      returing all the ones on whose the method
#                      didn't return nil/false
