NAME
Text::Aspell - Perl interface to the GNU Aspell library
SYNOPSIS
use Text::Aspell;
my $speller = Text::Aspell->new;
die unless $speller;
# Set some options
$speller->set_option('lang','en_US');
$speller->set_option('sug-mode','fast');
# check a word
print $speller->check( $word )
? "$word found\n"
: "$word not found!\n";
# lookup up words
my @suggestions = $speller->suggest( $misspelled );
# lookup config options
my $language = $speller->get_option('lang');
print $speller->errstr unless defined $language;
# fetch a config item that is a list
my @sgml_extensions = $speller->get_option_as_list('sgml-extension');
# fetch the configuration keys and their default settings
my $options = $speller->fetch_option_keys;
# or dump config settings to STDOUT
$speller->print_config || $speller->errstr;
# What dictionaries are installed as simple strings
my @dicts = $speller->list_dictionaries;
# or as an array of hashes
@dicts = $speller->dictionary_info;
print Data::Dumper::Dumper( \@dicts );
Here's an example how to create and use your own word list
Create a dictionary:
$ aspell --lang=en create master ./dictionary.local < space_separated_word_list
Then in your code:
use Text::Aspell;
my $speller = Text::Aspell->new;
die unless $speller;
$speller->set_option('master','./dictionary.local');
# check a word
print $speller->check( $word )
? "$word found\n"
: "$word not found!\n";
DESCRIPTION
This module provides a Perl interface to the GNU Aspell library. This module is to meet
the need of looking up many words, one at a time, in a single session, such as spell-
checking a document in memory.
The GNU C interface is described at:
http://aspell.net/man-html/Through-the-C-API.html#Through-the-C-API
It's worth looking over the way config and speller (manager) objects are created when
using the Aspell C API as some of that is hidden in the Text::Aspell module.
For example, with Text::Aspell you do not have to explicitly create a speller object. The
speller (manager) object is created automatically the first time you call suggest() or
check().
Note also that once the speller object is created some (all?) config options cannot be
changed. For example, setting configuration options such as "lang" are what determine
what dictionary Aspell will use. Once the speller object is created that dictionary will
be used. I.e. setting "lang" after the speller object is created will have no effect.
DEPENDENCIES
You MUST have installed GNU Aspell library version 0.50.1 or higher on your system before
installing this Text::Aspell Perl module. If installing Aspell using your operating
system's package management system, you may need to install the Aspell development package
(for example, on Debian libaspell-dev).
Aspell can source can be downloaded from:
http://aspell.net
There have been a number of bug reports because people failed to install aspell before
installing this module. This is an interface to the aspell library installed on your
system, not a replacement for aspell.
You must also have the English dictionary installed when running the module's test suite.
Also, please see the README and Changes files. README may have specific information about
your platform.
METHODS
The following methods are available:
$speller = Text::Aspell->new;
Creates a new speller object. New does not take any parameters (future version may
allow options set by passing in a hash reference of options and value pairs). Returns
"undef" if the object could not be created, which is unlikely.
Internally, new() creates an object to store Aspell structures (AspellConfig,
AspellSpeller, and a space for an error string and then calls new_aspell_config();
$speller->set_option($option_name, $value);
Sets the configuration option $option_name to the value of $value. Returns "undef" on
error, and the error message can be printed with $speller->errstr.
You should set configuration options before calling the $speller->create_speller
method. See the GNU Aspell documentation for the available configuration settings and
how (and when) they may be used.
$speller->remove_option($option_name);
Removes (sets to the default value) the configuration option specified by
$option_name. Returns "undef" on error, and the error message can be printed with
$speller->errstr. You may only set configuration options before calling the
$speller->create_speller method.
$string = $speller->get_option($option_name);
Returns the current setting for the given configuration option. The values are
strings. For configuration options that are lists used the "get_option_as_list()"
method.
Returns "undef" on error, and the error message can be printed with $speller->errstr.
Note that this may return different results depending on if it's called before or
after $speller->create_speller is called.
@list = $speller->get_option_as_list($option_name);
Returns an array of list items for the given option. Use this method to fetch
configuration values that are of type list.
Returns "undef" on error, and the error message can be printed with $speller->errstr.
Note that this may return different results depending on if it's called before or
after $speller->create_speller is called.
$options = $speller->fetch_option_keys;
Returns a hash of hashes. The keys are the possible configuration options and the
values is a hash with keys of:
desc : A short description of the option
default : The default value for this option
type : The data type of option (see aspell.h)
$speller->print_config;
Prints the current configuration to STDOUT. Useful for debugging. Note that this
will return different results depending on if it's called before or after
$speller->create_speller is called.
$speller->errstr;
Returns the error string from the last error. Check the previous call for an "undef"
return value before calling this method
$errnum = $speller->errnum;
Returns the error number from the last error. Some errors may only set the error
string ($speller->errstr) on errors, so it's best to check use the errstr method over
this method.
This method is deprecated.
$found = $speller->check($word);
Checks if a word is found in the dictionary. Returns true if the word is found in the
dictionary, false but defined if the word is not in the dictionary. Returns "undef"
on error, and the error message can be printed with $speller->errstr.
This calls $speller->create_speller if the speller has not been created by an explicit
call to $speller->create_speller.
@suggestions = $speller->suggest($word)
Returns an array of word suggestions for the specified word. The words are returned
with the best guesses at the start of the list.
$speller->create_speller;
This method is normally not called by your program. It is called automatically the
first time $speller->check() or $speller->suggest() is called to create a spelling
"speller".
You might want to call this when your program first starts up to make the first access
a bit faster, or if you need to read back configuration settings before looking up
words.
The creation of the speller builds a configuration profile in the speller structure.
Results from calling print_config() and get_option() will change after calling
create_speller(). In general, it's best to read config settings back after calling
create_speller() or after calling spell() or suggest(). Returns "undef" on error, and
the error message can be printed with $speller->errstr.
$speller->add_to_session($word)
$speller->add_to_personal($word)
Adds a word to the session or personal word lists. Words added will be offered as
suggestions.
$speller->store_replacement($word, $replacement);
This method can be used to instruct the speller which word you used as a replacement
for a misspelled word. This allows the speller to offer up the replacement next time
the word is misspelled. See section 6.3 of the GNU Aspell documentation for a better
description.
(July 2005 note: best to ignore any return value for now)
$speller->save_all_word_lists;
Writes any pending word lists to disk.
$speller->clear_session;
Clears the current session word list.
@dicts = $speller->list_dictionaries;
This returns an array of installed dictionary files. Each is a single string
formatted as:
[name]:[code]:[jargon]:[size]:[module]
Name and code will often be the same, but name is the complete name of the dictionary
which can be used to directly select a dictionary, and code is the language/region
code only.
$array_ref = $speller->$speller->dictionary_info;
Like the "list_dictionaries()" method, this method returns an array of hash
references. For example, an entry for a dictionary might have the following hash
reference:
{
'module' => 'default',
'code' => 'en_US',
'size' => 60,
'jargon' => 'w-accents',
'name' => 'en_US-w-accents'
},
Not all hash keys will be available for every dictionary (e.g. the dictionary may not
have a "jargon" key).
Upgrading from Text::Pspell
Text::Aspell works with GNU Aspell and is a replacement for the module Text::Pspell.
Text::Pspell is no longer supported.
Upgrading should be a simple process. Only one method name has changed: "create_manager"
is now called "create_speller". Code designed to use the old Text::Pspell module may not
even call the "create_manager" method so this may not be an issue.
The "language_tag" configuration setting is now called "lang".
Diffs for code that uses Text::Pspell might look like:
- use Text::Pspell;
+ use Text::Aspell;
- $speller = Text::Pspell->new;
+ $speller = Text::Aspell->new;
- $speller->create_manager || die "Failed to create speller: " . $speller->errstr;
+ $speller->create_speller || die "Failed to create speller: " . $speller->errstr;
If you used a custom dictionary installed in non-standard location and indexed the
dictionary with Aspell/Pspell .pwli files you will need to change how you access your
dictionary (e.g. by setting the "master" configuration setting with the path to the
dictionary). See the GNU Aspell documentation for details.
