+# plugin.py -- helper for writing gimp plugins
+# Copyright (C) 1997, James Henstridge.
+#
+# This is a small wrapper that makes plugins look like an object class that
+# you can derive to create your plugin. With this wrapper, you are pretty
+# much responsible for doing everything (checking run_mode, gui, etc). If
+# you want to write a quick plugin, you probably want the gimpfu module.
+#
+# A plugin using this module would look something like this:
+#
+# import gimp, gimpplugin
+#
+# pdb = gimp.pdb
+#
+# class myplugin(gimpplugin.plugin):
+# def query(self):
+# gimp.install_procedure("plug_in_mine", ...)
+#
+# def plug_in_mine(self, par1, par2, par3,...):
+# do_something()
+#
+# if __name__ == '__main__':
+# myplugin().start()
+
+import gimp
+
+class plugin:
+ def start(self):
+ # only pass the init()/quit() member functions to gimp.main() if the
+ # plug-in overrides them, to avoid the default NOP versions from being
+ # called unnecessarily. in particular, this avoids plug-ins that don't
+ # implement init() from being registered as having an init function,
+ # causing them to be run at each startup.
+ def get_func(name):
+ if getattr(self.__class__, name) != getattr(plugin, name):
+ return getattr(self, name)
+ else:
+ return None
+
+ gimp.main(get_func("init"),
