Hi,
Today I deployed for the first time my application.
It is far from complete, even though is not exactly trivial.
The size of the resulting directory (*excluding* the repository subdir) is well above 27MB.
It seems a bit steep for an application with one Perspective, two EditParts and one handful of ViewParts.
Am I linking in the whole universe or these numbers are normal?
How can I reduce (if possible at all) the size of this beast?
The heavyweights are, as expected, in the plugins subdir:
$ ls -lS
total 27521

...
My application is "it.condarelli.rcp.yw".
I tried searching, but I didn't find anything relevant.
OTOH several applications advertised as based on eclipse RCP have a much smaller footprint, so I suspect I'm doing something not quite right.
In particular the topmost item suggests I might be pulling in even Klingon and Sindarin codepages.
Thanks in Advance

I have an EMF model. Does it count as Resource?
I do *not* have a workspace, just I just open a model file in the filesystem.
I tried getting rid of help, but I got the error:
Cannot complete the install because one or more required items could not be found.
Software being installed: Writer Application 1.0.0 (it.condarelli.writer 1.0.0)
Missing requirement: Workbench 3.5.2.M20100113-0800 (org.eclipse.ui.workbench 3.5.2.M20100113-0800) requires 'bundle org.eclipse.help [3.2.0,4.0.0)' but it could not be found
Cannot satisfy dependency:
From: Writer Application 1.0.0 (it.condarelli.writer 1.0.0)
To: org.eclipse.ui.workbench [3.5.2.M20100113-0800]
Is there an "approved Way" to find out what can be deleted from dependencies?
The automated Writer.product->Dependencies->Add Required Plug-ins pulls in a lot of things obviously not needed.
Is there something better available?
TiA

The culprit was usage of FileStoreEditorInput which is in
org.eclipse.ui.ide. (why????)
I wrote my own LocalEditorInput/LocalEditorInputFactory and I managed to
get rid of ide (almost).

My current dependencies for my plugin is:
it.condarelli.writer.model,
org.eclipse.core.runtime,
org.eclipse.ui,
org.eclipse.jface.databinding,
org.eclipse.emf.databinding,
org.eclipse.ui.forms,
org.eclipse.core.filesystem,
org.eclipse.core.databinding.property,
org.eclipse.jface.text,
org.eclipse.ui.editors,
org.eclipse.nebula.widgets.ganttchart
Unfortunately the dependencies for the whole product (trimmed down by
hand, the automated dependency generator produces a *much* larger set) is:
<plugin id="com.ibm.icu"/>
<plugin id="it.condarelli.writer.model"/>
<plugin id="org.eclipse.compare"/>
<plugin id="org.eclipse.compare.core"/>
<plugin id="org.eclipse.core.commands"/>

<plugin id="org.eclipse.ui.win32" fragment="true"/>
<plugin id="org.eclipse.ui.workbench"/>
<plugin id="org.eclipse.ui.workbench.texteditor"/>
<plugin id="Writer"/>
where org.eclipse.ui.ide is back with some strange friends
(org.eclipse.ecf.*).
Two questions:
Is there any way to trim down this beast? It seems to me a refactoring
of some classes (e.g.: FileStoreEditorInput) would be beneficial for all
of us wanting to use RCP "just" as an Application Framework.
You said I should "replace com.ibm.icu with com.ibm.icu.base", but I
didn't find a way to do that. Can You tell me how to achieve that?
Many Thanks.
