SingularizePluralize

A simple Pharo library for transforming singular nouns to their plural form and vice versa. The implementation is based on the inflection library in Python.

Installation

To install the packages of SingularizePluralize, go to the Playground (Ctrl+OW) in your Pharo image and execute the following Metacello script (select it and press Do-it button or Ctrl+D):

Metacello new
  baseline: 'SingularizePluralize';
  repository: 'github://pharo-contributions/SingularizePluralize/src';
  load.

How to use it?

The package simply extends class String with two messages: asSingular and asPlural. Here are some examples of converting singular nouns to their plural forms:

'banana' asPlural. "bananas"
'man' asPlural. "men"
'woman' asPlural. "women"
'matrix' asPlural. "matrices"
'child' asPlural. "children"
'knife' asPlural. "knives"
'thesis' asPlural. "theses"
'auditorium' asPlural. "auditoria"

Similarly, we can convert plural nouns to their singular forms:

'bananas' asSingular. "banana"
'men' asSingular. "man"
'women' asSingular. "woman"
'matrices' asSingular. "matrix"
'children' asSingular. "child"
'knives' asSingular. "knife"
'theses' asSingular. "thesis"
'auditoria' asSingular. "auditorium"

If you find a mistake

Natural languages including English are very complex and irregular. It is hard to capture all rules and exceptions of pluralization with one algorithm. If you try to convert a noun to its singular/plural form and encounter a mistake, please report it by creating an issue with the title Singular (Plural) of "X" should be "Y" not "Z". I will create a rule or add an exception to cover that case.
