I've got about four plug-ins that I hope to release in January. This
includes my reader for GPX files, the latest edition of the Super
Select Tool, and a couple of Layer Utilities plug-ins.
Some of these are simple plug-ins with a single Jar and no
dependencies. So you can just drop them into the /ext folder of
OpenJUMP. Other of my plug-ins, like the Super Select Tool and the GPX
Reader, depend on external libraries and have I18N and configuration
files. I had cooked up part of an installer for the Super Select Tool
when I got to thinking that it might be nice to have a tool that could
be used to install, uninstall, and update plug-ins for OJ. It wouldn't
have to be a part of OJ, it could even run as a separate executable.
I was thinking of this simple interface:
public interface PlugInHandler
{
public abstract void installPlugIn(File argOpenJumpFolder);
public abstract void uninstallPlugIn(boolean argRemoveSharedLibraries);
public abstract void updatePlugIn();
}
I was thinking of another interface that could be used by
PlugInHandler.installPlugIn method implementations to show a standard
GUI to the user during plug-in installation/update:
public class PlugInInstallerGuiProvider
{
public abstract JPanel getLicensePanel();
public abstract JPanel getInstallConfigurationPanel();
public abstract JPanel getAboutPanel();
}
I thought a library providing these interfaces and some default
implementations might help us standardize plug-in management and make
the process of installing and removing plug-ins a little easier on the
end user.
Do you guys have any comments on this?
