deordinalize
A small gem to 'deordinalize' strings into the integers they reference.
Installation:
gem install deordinalize and require it. String now has the deordinalize method.
Usage:
deordinalize, for the time being, only supports ordinals from 1 to 100.
We can deordinalize numeric ordinals:
'1st'.deordinalize # => 1
'11th'.deordinalize # => 11
'99th'.deordinalize # => 99
Or we can deordinalize more verbose ordinals:
'first'.deordinalize # => 1
'eleventh'.deordinalize # => 11
'ninety-ninth'.deordinalize # => 99
Add a bang to the method to get the zero-based index of your ordinal:
'first'.deordinalize! # => 0
'eleventh'.deordinalize! # => 10
'ninety-ninth'.deordinalize! # => 98
This is meant to be hella useful in cucumber steps, like:
When /^I click on the (.+) item in the list$/ do |ordinal|
page.find( :xpath, "//li[#{ordinal.deordinalize!}]" ).click
end
