Common Lisp Package: CL-INFLECTOR-TEST



A common lisp library to easily pluralize and singularize English words.

This is a port of the ruby ActiveSupport Inflector module

Installation Hopefully eventually: > (ql:quickload 'cl-inflector)

Usage Example Usage:

> (use-package :cl-inflector) > (let ((dollars 1.7)  
        (users 34)  
        (purchases 1))  
       (format nil "The site has ~D ~A, with a total of ~D ~A and $~D ~A"   
               users (pluralize users "user")  
               purchases (pluralize purchases "purchase")  
               dollars (pluralize dollars "dollar")))  
"The site has 34 users, with a total of 1 purchase and $1.7 dollars" 

Basic Usage, plural-of and singular-of:

> (plural-of "octopus")  
"octopi" > (plural-of "datum")  
"data" > (singular-of "children")  
"child" > (singular-of "cats")  
"cat" > (singular-of "data")  

Basic Usage, pluralize:

> (pluralize 2 "octopus")  
"octopi" > (pluralize 1 "octopus")  

You can pass in the default plural to be used. If not, the inflector is used to determine the plural.

> (pluralize 2 "tooth" "teeth")  
"teeth" > (pluralize 2 "tooth")  

Use irregular to add an irregular:

> (singular-of "feet")  
"feet" > (irregular "foot" "feet") > (singular-of "feet")  
"foot" > (plural-of "foot")  

Use uncountable to add an uncountable:

> (plural-of "advice")  
"advices" > (singular-of "advice")  
"advice" > (singular-of "advices")  
"advice" > (uncountable "advice") > (plural-of "advice")
