Locale::Utils::Autotranslator - Base class to translate automaticly

VERSION

1.012

SYNOPSIS

Create your own translator

    package MyAutotranslator;

    use Moo;

    extends qw(
        Locale::Utils::Autotranslator
    );

    sub translate_text {
        my ( $self, $text ) = @_;

        my $translation = MyTranslatorApi
            ->new(
                from => $self->developer_language,
                to   => $self->language,
            )
            ->translate($text);

        return $translation;
    }

For interactive translation at the console, see also Locale::Utils::Autotranslator::Interactive.

Translate po files

    my $obj = MyAutotranslator->new(
        language                => 'de',
        # all following parameters are optional
        developer_language      => 'en', # en is the default
        before_translation_code => sub {
            my ( $self, $msgid ) = @_;
            ...
            return 1; # true: translate, false: skip translation
        },
        after_translation_code  => sub {
            my ( $self, $msgid, $msgstr ) = @_;
            ...
            return 1; # true: translate, false: skip translation
        },
        bytes_max               => 500,
    );
    $identical_obj = $obj->translate(
        'mydir/de.pot',
        'mydir/de.po',
    );
    # differs in case of bytes_max
    my $translation_count      = $obj->translation_count;
    my $item_translation_count = $obj->item_translation_count;

E.g. you have a limit of 100 free translations or 10000 words for 1 day you can skip further translations by return any false.

Use that before_... and after_... callbacks for debugging output.

Translate text directly

    my $obj = MyAutotranslator->new(
        ...
    );
    $msgstr = $obj->translate_any_msgid(
        'short text, long text with paragraphs or multiline text',
    );

DESCRIPTION

Base class to translate automaticly.

SUBROUTINES/METHODS

method new

see SYNOPSIS

method developer_language

Get back the language of all msgid's. The default is 'en';

method language

Get back the language you want to translate.

before_translation_code, after_translation_code, bytes_max

Get back the code references:

$code_ref = $obj->before_translation_code; $code_ref = $obj->after_translation_code;

Get back the bytes the translator API can handle:

$positive_int = $obj->bytes_max;

method translate

Translate po files.

    $obj->translate('dir/de.pot', 'dir/de.po');

That means: Read the de.pot file (also possible *.po). Translate the missing stuff. Write back to de.po file.

method translate_any_msgid

Translate in one or more steps. Count of steps depend on bytes_max.

    $msgstr = $obj->translate($msgid);

method with_paragraphs (normally not used directly)

Called if bytes_max < length of whole text.

Split text into paragraphslines, remove empty lines around. Translate line by paragraph. Add the empty lines and join the translated lines.

    $msgstr = $self->with_paragraths(
        $msgid,
        sub {
            return $self->translate_paragraph($_);
        },
    );

method with_lines (normally not used directly)

Called if bytes_max < length of a paragraph.

Split paragraph into lines, remove the whitespace noise around. Translate line by line. Add the whitespace noise and join the translated lines.

    $msgstr = $self->with_lines(
        $msgid,
        sub {
            return $self->translate_line($_);
        },
    );

method translate_text

In base class there is only a dummy method that returns q{}.

The subclass has to implement that method. Check the code of Locale::Utils::Autotranslator::ApiMymemoryTranslatedNet to see how to implement.

method comment

Set a typical comment to mark the translation as translated by ... in API class. Get back that comment.

E.g.

    $self->comment('translated by: api.mymemory.translated.net');

method translation_count

Get back the count of translations. This is not the count of translated messages. This is the count of successful translate_text calls if it would not be splitted into paragraphs and lines.

For plural forms we have to translate 1 to 6 times. That depends on language.

my $translation_count = $obj->translation_count;

method item_translation_count

Get back the count of splitted translations by paragraphs or lines. This is not the count of translated messages, this is the count of successful translate_text calls.

my $translation_count = $obj->translation_count;
