Requirements
Raspell requires Aspell version 0.6 (www.aspell.net) and at least one Aspell dictionary.
Mac:
sudo port install aspell aspell-dict-en
Ubuntu:
sudo apt-get install aspell libaspell-dev aspell-en
Installation
sudo gem install raspell
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.
