When is a plugin Editable? [message #47101]

I am using the PDE API, and want to add Extensions to a plugin, but all my
plugins return false to isEditable().

The basic code I am using is:

IPluginModelBase[] allModels = PluginRegistry.getActiveModels();

allContributers = Arrays.asList(allModels);
writeableContributers = new ArrayList<IPluginModelBase>();
for (IPluginModelBase model : getAllContributers()){
if (model.isEditable()){
writeableContributers.add(model);
}
}

In this case my "writeable" collection is always empty.

I have the source of (some of) the plugins in my workspace, and I can edit
them using the PDE itself, so I'm a bit unlcear as to what I need to do to
make them editable.

Thanks in advance,

Richard

It's currently not possible, read the Javadoc of IPluginModelBase.

There's plenty of bugs open around this API issue:

190324: [API] Open API for programmatically adding extensions
https://bugs.eclipse.org/bugs/show_bug.cgi?id=190324
216037: [API] Way to modify MANIFEST files
https://bugs.eclipse.org/bugs/show_bug.cgi?id=216037
190324: [API] Open API for programmatically adding extensions
https://bugs.eclipse.org/bugs/show_bug.cgi?id=190324

There are ways to do this using not API, but before I say anything, what
are you trying to do :)?

Hi Chris,

So the context is:

What we have at the moment are a number of different Extension Points that
often impact on each other. Also our users have built a hierarchy of
contributions to these extension points, so we are writing a little "SDK"
to present them in a way that makes sense to users of the tool.

In this specific example (I'm starting simple), users can add menu/toolbar
actions to do slightly different things to the built in tools. When they
do this, they will probably want to disable the builtins (or even
contributions that some one else made further down their plugin hierarchy).

The way to disable is through a different extension point.

So... the "SDK" shows the all things they have contributed from any of
their plugin along side the built-ins, and I want to be able to
right-click and create a "disable" contribution based on the selection in
that table.

The intent is NOT that the contribution is made immediately to the current
workspace, I just want to add it to a plugin that is being "edited"
locally for subsequent deployment.

Hope that makes sense.

Richard

PS I don't think the JavaDoc I read really suggests this is not possible..
