New in version 5.0.1.
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 plugin_unregister.
plugin_register has a parameter name. It is required parameter:
plugin_register name
Here is a sample that registers QueryExpanderTSV query expander that is included in ${PREFIX}/lib/groonga/plugins/query_expanders/tsv.so.
Execution example:
plugin_register query_expanders/tsv
# [[0, 1337566253.89858, 0.000355720520019531], true]
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.
plugin_register returns true as body on success such as:
[HEADER, true]
If plugin_register fails, error details are in HEADER.
See Output format for HEADER.
