Actions are 'programmed' admin tasks which can be performed by selected regular users from the Task Center. An action could be creation of backend users, fixed SQL SELECT queries, listing of records, direct edit access to selected records etc.
This TYPO3 allows to run some TYPO3 Backend admin tasks like creation of new Backend users as a non-admin user if properly set up. It hooks into extension "taskcenter" for the GUI part.
The functionality was part of the TYPO3 Core until TYPO3 v10.0, and moved into its own extension, receiving its own public repository.
The latest version can be installed via TER (http://typo3.org) or via composer by adding ''composer require friendsoftypo3/sys-action'' in a TYPO3 v10.0+ installation.
The extension has been part of TYPO3 Core for a very long time but never received much love. It may become more healthy if maintained as third party extension and has been extracted for this reason.
Feel free to submit any pull request, or add documentation, tests, as you please. We will publish a new version every once in a while, depending on the amount of changes and pull requests submitted.
The extension is published under GPL v2+, all included third-party libraries are published under their respective licenses.
Many contributors have been working on this area while this functionality was part of the TYPO3 Core. This package is now maintained by a loose group of TYPO3 enthusiasts inside the TYPO3 Community.
