Darcs.Util.English

Description

This modules provides rudimentary natural language generation (NLG) utilities. That is, generating natural language from a machine representation. Initially, only English is supported at all. Representations are implemented for:

  • countable nouns (plurality); and * lists of clauses (foo, bar and/or baz).

Synopsis

Documentation

englishNum :: Countable n => Int -> n -> ShowS

 englishNum 0 (Noun "watch") "" == "watches"
 englishNum 1 (Noun "watch") "" == "watch"
 englishNum 2 (Noun "watch") "" == "watches"

class Countable a where

Things that have a plural and singular spelling

Methods

plural :: a -> ShowS

singular :: a -> ShowS

newtype Noun

This only distinguishes between nouns with a final -ch, and nouns which do not. More irregular nouns will just need to have their own type

 plural (Noun "batch") "" == "batches"
 plural (Noun "bat")   "" == "bats"
 plural (Noun "mouse") "" == "mouses" -- :-(
