The package allows automatically extracting translation IDs from PHP source files and writing them to one of the translator message sources.

Requirements

  • PHP 8.0 or higher.

Installation

The package could be installed with Composer:

composer require yiisoft/translator-extractor

Configuration

You need configure MessageReader and MessageWriter in config file of the package, config/console/translator-extractor.php:

For example, when using PHP MessageSource the config will be the following using relative path:

use \Yiisoft\Translator\Message\Php\MessageSource;

return [
    Extractor::class => [
        '__construct()' => [
            [
                DynamicReference::to([
                    'class' => ExtractorCategorySource::class,
                    '__construct()' => [
                        'app',
                        'messageReader' => DynamicReference::to(static fn () => new MessageSource($params['yiisoft/translator-extractor']['messagePath'])),
                        'messageWriter' => DynamicReference::to(static fn () => new MessageSource($params['yiisoft/translator-extractor']['messagePath'])),
                    ],
                ]),
            ],
        ],
        '->translate' // optional, default value for Translation call to look for.
    ],
];

And in params.php file you can configure parameters of a message source:

return [
    'yiisoft/yii-console' => [
        'commands' => [
            'translator/extract' => ExtractCommand::class,
        ],
    ],
    'yiisoft/translator-extractor' => [
        // Using relative path:
        'messagePath' => dirname(__DIR__, 5) . '/messages',
    ],
];

Or if with using PHP MessageSource the config will be the following using Aliases:

use \Yiisoft\Translator\Message\Php\MessageSource;

return [
    Extractor::class => [
        '__construct()' => [
            [
                DynamicReference::to([
                    'class' => ExtractorCategorySource::class,
                    '__construct()' => [
                        'app',
                        'messageReader' => DynamicReference::to(static fn (Aliases $aliases) => new MessageSource($aliases->get('@message'))),
                        'messageWriter' => DynamicReference::to(static fn (Aliases $aliases) => new MessageSource($aliases->get('@message'))),
                    ],
                ]),
            ],
        ],
    ],
];

Attention: Both MessageReader and MessageWriter should be configured for using the same MessageSource. The extractor needs it to work with existing messages.

General usage

./yii translator/extract

This command will recursively find all messages in the code starting with the current directory and will save it into a message source for default language en. You can specify the path explicitly:

./yii translator/extract /path/to/your/project

Notice: By default extractor has vendor directory in the application directory excluded. To include it you can specify empty value for except:

./yii translator/extract /path/to/your/project --except=''

Full list of options:

Usage:
  translator/extract [options] [--] [<path>]

Arguments:
  path                       Path for extracting message IDs.

Options:
  -L, --languages=LANGUAGES  Comma separated list of languages to write message sources for. By default it is `en`. [default: "en"]
  -C, --category=CATEGORY    Default message category to use when category is not set. [default: "app"]
  -E, --except[=EXCEPT]      Exclude path from extracting. (multiple values allowed)
  -O, --only[=ONLY]          Use the only specified path for extracting. (multiple values allowed)

Specify languages

You can specify multiple languages to write IDs into:

./yii translator/extract --languages=en,ru

Or in short format:

./yii translator/extract -Lru

Specify default category

Also, you can specify default message category to use when category is not set.

./yii translator/extract --category=your_category_name

Using except option

To exclude all directories named dir1 use --except:

./yii translator/extract --except=**/dir1/**

To exclude both vendor and tests directories the following options could be used:

./yii translator/extract --except=./vendor/** --except=./tests/**

Using only option

To parse only test.php files in any directory use --only option:

./yii translator/extract --only=**/test.php

To parse only /var/www/html/test.php file use:

./yii translator/extract --only=/var/www/html/test.php

For more info about except and only parameters check documentation of yiisoft/files package.

Working with gettext

The package currently does not support extracting messages into gettext format. To extract messages for gettext, you may use the following shell script (in Linux-based OS):

find src/ -name *.php | xargs xgettext --from-code=utf-8 --language=PHP --no-location --omit-header --sort-output --keyword=translate --output="locales/category.pot"

for d in locales/*/ ; do
    for i in locales/*.pot; do
        if [ ! -f "$d$(basename "$i" .pot).po" ]; then
            touch "$d$(basename "$i" .pot).po"
        fi

        msgmerge --update --silent --backup=off "$d$(basename "$i" .pot).po" $i
    done
done
