Hello,
I was wondering if it is not useful a command line interface to interact with piwigo. There are many jobs could be done using a command line, including cron interface for repetitive maintenance, manage passwords including lost admin, batch tool for time consuming jobs running in low priority process, and many ones one can include via plugins. If core implements a command line interface, all plugins may use it for any purpose.
This request is inspired on owncloud command line interface (https://doc.owncloud.org/server/7.0/adm … mmand.html).
