public class PluginJAR
Loads and unloads plugins.
actions.xml
defining plugin actions.
Only one such file per plugin is allowed. See ActionSet
for
syntax.browser.actions.xml
defining file system
browser actions.
Only one such file per plugin is allowed. See ActionSet
for
syntax.dockables.xml
defining dockable windows.
Only one such file per plugin is allowed. See DockableWindowManager
for
syntax.services.xml
defining additional services
offered by the plugin, such as virtual file systems.
Only one such file per plugin is allowed. See ServiceManager
for
syntax..props
containing name/value pairs
separated by an equals sign.
A plugin can supply any number of property files. Property files are used
to define plugin men items, plugin option panes, as well as arbitriary
settings and strings used by the plugin. See EditPlugin
for
information about properties used by jEdit. See
java.util.Properties
for property file syntax.Plugin
.
This class, known as the plugin core class must extend
EditPlugin
and define a few required properties, otherwise it is
ignored.
jEdit.addPluginJAR(String)
and
jEdit.removePluginJAR(PluginJAR,boolean)
methods. Furthermore, the
plugin core class might not be loaded until the plugin is first used. See
EditPlugin.start()
for a full description.
