Text::SpellChecker - OO interface for spell-checking a block of text

SYNOPSIS

            "$word : ",
            (join "\t", @{$checker->suggestions}),
            "\nChoose a new word : ";
        chomp (my $new_word = <STDIN>);
        $checker->replace(new_word => $new_word) if $new_word;
    }

DESCRIPTION

This module is a thin layer above either Text::Aspell or Text::Hunspell (preferring the latter if available), and allows one to spellcheck a body of text.

Whereas Text::(Hu|A)spell deals with words, Text::Spellchecker deals with blocks of text. For instance, we provide methods for iterating through the text, serializing the object (thus remembering where we left off), and highlighting the current misspelled word within the text.

METHODS

$checker = Text::SpellChecker->new(text => $text, from_frozen => $serialized_data, lang => $lang, options => $options)

Send either the text or a serialized object to the constructor. Optionally, the language of the text can also be passed. If no language is passed, $ENV{LANG} will be used, if it is set. If it is not set, the default language will be "en_US".

$options are checker-specific options (see below).

$checker = new_from_frozen($serialized_data)

This is provided separately, so that it may be overridden for alternative serialization techniques.

$str=$checker->serialize

Represent the object in its current state.

$checker->reset

Reset the checker to the beginning of the text, and clear the list of ignored words.

$word = $checker->next_word

Returns the next misspelled word.

$checker->current_word

Returns the most recently returned word.

$checker->replace(new_word => $word)

Replace the current word with $word.

$checker->ignore_all

Ignore all subsequent occurences of the current word.

$checker->replace_all(new_word => $new_word)

Replace all subsequent occurences of the current word with a new word.

$checker->suggestions

Returns a reference to a list of alternatives to the current word in a scalar context, or the list directly in a list context.

$checker->text

Returns the current text (with corrections that have been applied).

$checker->highlighted_text

Returns the text, but with the current word surrounded by $Text::SpellChecker::pre_hl_word and $Text::SpellChecker::post_hl_word.

$checker->set_options

Set checker-specific options. Currently only aspell supports setting options, e.g.

    $checker->set_options(aspell => { "extra-dicts" => "nl" } );
    

CONFIGURATION OPTIONS

$Text::SpellChecker::pre_hl_word

Set this to control the highlighting of a misspelled word.

$Text::SpellChecker::post_hl_word

Set this to control the highlighting of a misspelled word.

$Text::SpellCheckerDictionaryPath{Hunspell}

Set this to the hunspell dictionary path. By default /usr/share/hunspell.

This directory should have $lang.dic and $lang.aff files.
