English natural language parser for numbers.
-
Parse ‘five’ to return 5
-
Parse ‘seven hundred and fifty two billion, four hundred and twenty million, sixty thousand and forty two’ to return 752,420,060,042
-
Parse ‘siebenundzwanzig’ to have it fail because it doesn’t recognise German.
Recognises numbers in the trillions.
The English language has explicit rules for expressing numbers. Numeruno attempts to recognise strings based on these rules.
Check out wiki.github.com/brentsnook/numerouno for details.
sudo gem install numerouno
Or grab the code from Github and build yourself:
git clone git://github.com/brentsnook/numerouno.git cd numerouno rake install_gem
Just require numerouno to add magical number parsing powers to your strings:
require 'numerouno' 'sixty five'.as_number => 65 '65'.as_number => 65 'two bit varmint'.sub_numbers => '2 bit varmint'
Or if you’re a sook who doesn’t like the idea of String being opened up:
require 'numerouno-parsing' Numerouno.parse 'sixty five' Numerouno.replace 'two bit varmint'
One serving suggestion is to use it to use it with your Cucumber steps.
meaning_steps.rb
require 'numerouno' When /the meaning of life is (.+)/ do |number| 42.should == number.as_number end
meaning_of_life.feature
Then the meaning of life is forty two
