Hi,
How can I obtain a list of all natures registered with the platform? (i.e.
all hooks to the org.eclipse.core.resources.natures extension point). I
need a list of all of them regardless of whether they are in use by a
project or not...
Thanks!

You can use the Plug-in registry APIs to find plug-ins which contribute
to a certain extension point.
// ID for the extension point of interest
String theExtensionPoint = "org.eclipse.core.resources.natures";
// get access to plug-in registry
IPluginRegistry pluginRegistry = Platform.getPluginRegistry();
// get the extension-point that we're interested in
// so we can find the extensions to it
IExtensionPoint point =
pluginRegistry.getExtensionPoint(theExtensionPoint);
// find all extensions to the extension-point
IExtension[] extensions = point.getExtensions();
// loop through the extensions
for (int i = 0; i < extensions.length; i++)
{
IExtension currentExtension = extensions[i];
// output each extension
System.out.println(currentExtension.getUniqueIdentifier());
}

Indeed. I had managed to dig it up in the API and have actually created my
first plugin (ooh, the pride of it! :-)) which provides a view with the
following:
- It is a view which shows a tree of all open projects.
- Each project has a list of nature ids registered with it as children.
- You may remove natures from a project using an action in the view.
- You may add a nature to a project by selecting from a list of natures.
Of course, selecting natures which are incompatible will fail, etc.
Is this a really bad idea? I was surprised there wasn't such a thing already
in Eclipse (or is there? argh!). I wrote it because I am writing my own
nature which adds my own builder that processes some files written in a
custom language. It's a convenient way to enable / disable the builder. If
someone finds it useful, I can send you my totally inappropriate newbie
code... :-P
