As of Luggage 3.2.2 we've made it easier to query Luggage for its version number. There are two ways to get the version number: on the site status page, and via drush.
Version from status page
admin/reports/status and find the version in the list of status reports
Version from drush
Luggage also provides a drush command to check versions. This can be useful in scripts that help you manage multiple sites.
# drush @alias luggage-version LUGGAGE: 3.2.2 LUGGAGE_ISU: 3.6
If you want to single out just one product without the label with drush, you can pass the option
# drush @alias luggage-version --product=LUGGAGE 3.2.2
luggage-version can be shortened to
# drush @alias lv --product=LUGGAGE 3.2.2
Make a version for your fork
You can add a version to your fork of luggage. For example, we added a version to Luggage ISU. To add a version for your fork/product add a new PHP file to the root of the Drupal installation. Name it
<PRODUCT>_VERSION.php. So, for example, Luggage ISU has a file called
LUGGAGE_ISU_VERSION.php. The contents of the file should be as follows:
<?php $version = "1.2.3";
$version should be a string. Once you have this, you should see the your product version on the site status page and with drush.
