Sex Machine
This gem uses the underlying data from the program "gender" by Jorg Michael (described here). Its use is pretty straightforward:
>> require 'sexmachine'
>> d = SexMachine::Detector.new
>> d.get_gender("Bob")
:male
>> d.get_gender("Sally")
:female
>> d.get_gender("Pauley") # should be androgynous
:andy
The result will be one of andy (androgynous), male, female, mostly_male, or mostly_female. Any unknown names are considered andies.
I18N is fully supported:
>> d.get_gender("?lfr?n")
:female
Additionally, you can give preference to specific countries:
>> d.get_gender("Jamie")
=> :female
>> d.get_gender("Jamie", :great_britain)
=> :mostly_male
If you have an alterative data file, you can pass that in as an optional filename argument to the Detector. Additionally, you can create a detector that is not case sensitive (default is to be case sensitive):
>> d = SexMachine::Detector.new(:case_sensitive => false)
>> d.get_gender "sally"
=> :female
>> d.get_gender "Sally"
=> :female
Try to avoid creating many Detectors, as each creation means reading in the data file.
