I have several projects in Eclipse. And I have a plugin that is activated/executed by popupmenu when you right click on any project.

And I need to hide/show some submenus in in the popupmenu depending on System property. I address it in plugin.xml as follows:

<objectContribution
           adaptable="true"
           id="com.qonline.qolclipse.contribution1"
           objectClass="org.eclipse.core.resources.IProject">
        <action
               class="com.qonline.eclipse.popup.actions.AddQOLNature"
              id="com.qonline.qolclipse.addqolnature"
              label="Add QOL nature"
              menubarPath="com.qonline.qolclipse.main/group1">
        </action>
    	
         <visibility>
           <systemProperty
                 name="qolclipse.connected"
                 value="true">
           </systemProperty>
        </visibility>
     
      </objectContribution>

. . . . ..
This works fine with single project. I am setting "qolclipse.connected" SystemProperty to true or false when I want to hide or show the action[see code above]. But when I have more than one projects it does not work, because all projects are checking the same <systemProperty> [see above code].

Because of this fact [ all projects are checking the same <systemProperty>], I want to use IProject.getName() in plugin.xml, so that for every project I can have specific Systemproperty with project's name.

I need something like this:

 <systemProperty
                 name="IProject.getName()"
                 value="true">
</systemProperty>

But I coud not find a way how to use the external variable [IProject.getName()] in plugin.xml. I noticed that we can use some contants from plugin.properties, BUT what about variables?

HOW CAN I USE VARIABLE EXPRESSIONS in plugin.xml or plugin.properties?

Could you please inform me if there are any other ways of hiding/showing the submenus. I need <visibility> not <enablement>?

Any guidelines, tips, links, advice.. are appreciated.

Thanks! Smile

Actually, you probably want to set a persistent project property using
the IResources/IProject API. Then use that, since it is per-project.
In objectContributions I believe there's a published filter, like
mentioned on org.eclipse.ui.IResourceActionFilter

If you use <enablement/>, then you will be using core expressions and
the selection will be a collection of IProjects. Then you use something
like:
<iterate ifEmpty="false">
<adapt type="org.eclipse.core.resources.IProject">
// here you can use property testers to test either
// the project persistent property or the project name
// see links in my sig for more information
</adapt>
</iterate>
