Requirements

• Aspell version 0.6 (www.aspell.net)

Basic usage

Aspell lets you check words and suggest corrections. For example:

require 'rubygems'
require 'raspell'

speller = Aspell.new("en_US")
speller.suggestion_mode = Aspell::NORMAL

string = "my haert wil go on"

string.gsub(/[\w\']+/) do |word| 
  if !speller.check(word) 
    # word is wrong
    puts "Possible correction for #{word}:"
    puts speller.suggest(word).first
  end
end

This outputs:

Possible correction for haert:
heart
Possible correction for wil:
Will

Note that suggest returns an array of suggestions even for words that are correctly spelled.

Options

The most useful options are suggestion_mode, and the passthrough option ignore_case. Passthrough options have to be set as so:

speller.set_option("ignore-case", "true")

See aspell.net/man-html/The-Options.html for a list of the passthrough options.
