How to trim down application size? [message #504052]

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:

...

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
Mauro

Are you using org.eclipse.ui.ide? If not, get rid of it (it contains
mostly code to work with core.resources, which you haven't included).
Are you using org.eclipse.help? And org.eclipse.text, that's the text
editor support.

As for com.ibm.icu, if you don't need the i18n support you can replace
it with com.ibm.icu.base (a plugin listed on the
http://download.eclipse.org/eclipse/downloads/drops/R-3.5.1- 200909170800/index.php
page, for example).

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?

No, I'm just curious why you have org.eclipse.ui.ide in there. Remove
it if you can, it's for providing workbench services that deal with
IResources (the org.eclipse.core.resources plugin). That's for
workspaces, which you don't have.

A quick glance through the original list and it looks like the only
other thing you can do is to replace com.ibm.icu with com.ibm.icu.base
(so it is significantly smaller).

You might be right, as long as you use org.eclipse.ui.workbench you
can't get rid of help.

Later,
PW

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.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.

The com.ibm.icu replacement, com.ibm.icu.base, is on the Eclipse SDK
download pages, like
http://download.eclipse.org/eclipse/downloads/drops/R-3.5.2- 201002111343/

As long as you depend on org.eclipse.ui.ide, you will get all of
core.resources, p2, and p2 pulls in ecf.

Get rid of org.eclipse.ui.ide dependencies. That's the only way. If
you've copied out the LocalEditorInput/LocalEditorInputFactory code,
what else do you depend on?
