.. groonga-command
.. database: commands_plugin_register
``plugin_register``
===================
.. versionadded:: 5.0.1
Summary
-------
``plugin_register`` command registers a plugin. You need to register a plugin
before you use a plugin.
You need just one ``plugin_register`` command for a plugin in the same
database because registered plugin information is written into the
database. When you restart your ``groonga`` process, ``groonga``
process loads all registered plugins without ``plugin_register`` command.
You can unregister a registered plugin by :doc:`plugin_unregister`.
Syntax
------
This command takes only one required parameter::
plugin_register name
Usage
-----
Here is a sample that registers ``QueryExpanderTSV`` query expander
that is included in
``${PREFIX}/lib/groonga/plugins/query_expanders/tsv.so``.
.. groonga-command
.. include:: ../../example/reference/commands/plugin_register/query_expanders_tsv.log
.. plugin_register query_expanders/tsv
You can omit ``${PREFIX}/lib/groonga/plugins/`` and suffix (``.so``).
They are completed automatically.
You can specify absolute path such as ``plugin_register
/usr/lib/groonga/plugins/query_expanders/tsv.so``.
Return value
------------
``plugin_register`` returns ``true`` as body on success such as::
[HEADER, true]
If ``plugin_register`` fails, error details are in ``HEADER``.
See :doc:`/reference/command/output_format` for ``HEADER``.
