NAME

Text::Mecabist - Text::MeCab companion for Acmeist

SYNOPSIS

use utf8;
use Text::Mecabist;

my $parser = Text::Mecabist->new();

print $parser->parse('庭に鶏', sub {
    my $node = shift;
    $node->text($node->reading .'!') if $node->readable;
});

# ニワ!ニ!ニワトリ!

DESCRIPTION

Text::Mecabist is a sub project from my Japanese transforming Acme toys.

Although it is overhead exists than using Text::MeCab directly, but helpful especially around to encode/decode with mecab encoding.

METHODS

Text::Mecabist->new()

my $parser = Text::Mecabist->new();

Craete parser object. Arguments can take are optional and same as Text::MeCab->new().

my $parser = Text::Mecabist->new({
    node_format => '%m,%H',
    unk_format  => '%m,%H',
    bos_format  => '%m,%H',
    eos_format  => '%m,%H',
    userdic     => 'user.dic',
});

Text::Mecabist->encoding()

print Text::Mecabist->encoding->name; # => "utf8" or something

This class method returns Encode::Encoding object.

$parser->parse($text [, $cb ])

Parses text by mecab, returns Text::Mecabist::Document object that contains HUGE list of Text::Mecabist::Node objects.

$parser encodes $text by mecab encoding automatically.

Optional $cb is called for all of those nodes.

$doc = $parser->parse('...', sub {
    my $node = shift; # => is a Text::Mecabist::Node
});

Text::Mecabist::Document

$doc->stringify()

Shortcut to $doc->join('text'). Document object is overloading as a string.

print $doc; # boon

$doc->nodes()

Accessor. Arrayref of Text::Mecabist::Node-s.

$doc->join($field)

$doc = $parser->parse('庭の鶏')
$text = $doc->join('reading'); # => "ニワノニワトリ"

Return combined text by specific field. Same as

my $res = "";
for my $node (@{ $doc->nodes }) {
    $res .= $node->$field;
}

Text::Mecabist::Node

from Text::MeCab::Node

$node->id;
$node->length;
$node->rlength;
$node->rcattr;
$node->lcattr;
$node->stat;
$node->isbest;
$node->alpha;
$node->beta;
$node->prob;
$node->wcost;
$node->cost;
$node->surface; # decoded
$node->feature; # decoded
$node->format;  # decoded

divided feature

$node->pos;  # 品詞
$node->pos1; # 品詞細分類1
$node->pos2; # 品詞細分類2
$node->pos3; # 品詞細分類3
$node->inflection_type; # 活用型
$node->inflection_form; # 活用形
$node->lemma;   # 原形
$node->reading; # 読み
$node->pronunciation; # 発音
$node->extra1;
$node->extra2;
$node->extra3;
$node->extra4;
$node->extra5;
$node->extra; # all of extra, with comma

traversal nodes

$node->has_next; # 1 or 0
$node->next; # next Text::MeCab::Node or undef
$node->has_prev; # 1 or 0
$node->prev; # prev Text::MeCab::Node or undef

helper

$node->readable; # 1 or 0
$node->is('名詞'); # 1 or 0
$node->text; # copy of $node->surface but RW.
$node->skip(0); # skip in join() if set 1
$node->last(0); # last in join() if set 1
