add .xpt template [message #233305] Wed, 10 June 2009 14:37 Go to next message

Originally posted by: aurelien.pupier.esial.net

Hi,

I want to add some template to generate custom files.

I can modify existing, I mean : I modify an existing .xpt, so the
generated class is correctly modified

But when I create a new .xpt file in order to generate a class... it
seems that the .xpt is not used...

The new .xpt files are in the same folder of existing templates.

The most strange is that at the first "generate diagram code", there was
a trace in the log which indicates errors but now there is no more trace
in the log at the "generate diagram code" invocation.

Is there something to do to consider the new .xpt files?

Thanks for any help


One of my new .xpt file(PropertySourceExtended.xpt) :

«IMPORT "http://www.eclipse.org/gmf/2008/GenModel
«IMPORT "http://www.eclipse.org/emf/2002/Ecore

«DEFINE Class FOR gmfgen::GenCustomPropertyTab»
«EXPAND xpt::Common::copyright FOR sheet.editorGen-»
package «sheet.packageName»;

«EXPAND xpt::Common::generatedClassComment»
public class PropertySourceExtended extends
org.eclipse.emf.edit.ui.provider.PropertySource implements
org.eclipse.ui.views.properties.IPropertySource{
«EXPAND createPropertyDescriptorMethod»


}
«ENDDEFINE»

«DEFINE createPropertyDescriptorMethod FOR gmfgen::GenCustomPropertyTab-»
«EXPAND xpt::Common::generatedMemberComment»
protected IPropertyDescriptor
createPropertyDescriptor(org.eclipse.emf.edit.provider.IItem PropertyDescriptor
itemPropertyDescriptor) {
return new PropertyDescriptorExtended(object,
itemPropertyDescriptor);
}
«ENDDEFINE»

You can override/aspect exisitng GMF templates, but if you created a new
one you have to either call it from any other existing (customized) GMf templates
- to inject corresponding code into GMf-generated files or call separate
generate code process (e.g. using ANT task) executing this template.

OK, thanks.
So... some more question.
I think that I will call it from existing GMF templates... but need help
for that too

I looked there
http://www.openarchitectureware.org/pub/documentation/4.1/r2 0_xPandReference.pdf

and find that we can call an other definition in an other template file
if we specified the name of the template...
«EXPAND my::templates::TemplateFile::definitionName
FOR myModelElement»

So I try various things and I have some questions :
Where do I start the path? (my??)
What is the myModelElement? (gmfgen::GenCustomPropertyTab??)

info :
templates
-xpt
-propsheet
- existingTemplate.xpt where I put the EXPAND instruction [1]
- newTemplate.xpt with [2]


I thought it is something like that but it's seems not...

[1]
[...]
«EXPAND xpt::propsheet::newTemplate::Class
FOR gmfgen::GenCustomPropertyTab»
[...]

[2]
[...]
«DEFINE Class FOR gmfgen::GenCustomPropertyTab»
//what i want to generate
«ENDDEFINE»
[...]

Hello Aurelien,

> Where do I start the path? (my??)
In .gmfgen model there are two properties:
- GenEditorGenerator.Dynamic Templates (boolean)
- GenEditorGenerator.Template Directory (string) - see http://wiki.eclipse.org/GMF_GenModel_Hints#GenEditorGenerato r

So, you can:
- create new template in a file: /project1/customTemplates/folder1/TemplateFile.xpt
- set Template Directory to "/project1/customTemplates"
- use «EXPAND folder1::TemplateFile::definitionName FOR myModelElement» to
execute definition "definitionName" from this file.

> What is the myModelElement? (gmfgen::GenCustomPropertyTab??)
myModelElement is a name of variable or reference/attribute. It's type can
be gmfgen::GenCustomPropertyTab. Here is an example from GMF templates:

«DEFINE Class FOR gmfgen::GenCustomPropertyTab»
.............
public class «className» extends «EXPAND extendsList» «EXPAND implementsClause»{
.............
«ENDDEFINE»

«EXPAND extendsList» is a way to call another definition with name "extendsList"
(defined in this file). This call is equivalent to: «EXPAND extendsList FOR
self» where "self" is a contextual parameter name (instanceof gmfgen::GenCustomPropertyTab).
If you need to call a definition using any feature of contextual parameter
you can use constructions like:

«EXPAND myDefinition FOR self.className»

the the following definition will be called:
«DEFINE myDefinition FOR String»
.............
«ENDDEFINE»

where "String" is a type of gmfgen::GenCustomPropertyTab::className attribute
in the model. Instead of shortname of a definition located in same file you
can use full name like: myFolder::MyTemplate::myDefinition

> [1]
> [...]
> «EXPAND xpt::propsheet::newTemplate::Class
> FOR gmfgen::GenCustomPropertyTab»
It should be something like:
«EXPAND xpt::propsheet::newTemplate::Class FOR self.customPropertyTab»

Try «EXPAND xpt::propsheet::PropertySourceExtended::Class» instead

thanks a lot!!
Now the code is well-generated but... in the same file that it is
called. or I want to generate a new file

I tried to create a new file with :
«FILE 'templates/xpt/propsheet/PropertySourceExtended.java'»
«EXPAND xpt::propsheet::PropertySourceExtended::Class»
«ENDFILE»

//also tried with TO_SRC

But I catch this error while generating :

Hello Aurelien,

Rigth. FILE directive is not supported in GMF xpand.
This is why I said you in the very first letted that you probably have to
use ANT task for it.
Another option is to extend org.eclipse.gmf.codegen.util.Generator, create
custom popup menu action using this class for code generation, deploy everything
to currently running platform and use this action for diagram code generation.

Will it be supported with the new version of GMF which use QvTo?

if you have an example ant task to generate it...

Say me if I'm right.
I can generate all diagram code using an ant task? or is there
limitations? which?

calling a doGenerateJavaClass I suppose at first sight?

No, it's not supported now. You can generate diagram code using UI action
only and you can generate additional classes using modified UI action or
using ant file.

Right you can call doGenerateJavaClass() from GeNeratorExt class.

I tried this.

I created a custom popup menu which launch :
a CustomExecuteTemplatesAction extends ExecuteTemplatesAction, overriden
the createOperation Method by return CustomExecuteTemplatesOperation
CustomExecuteTemplatesOperation extends ExecuteTemplatesOperation,
overriden the createGenerator which return a CustomGenerator
CustomGenerator extends Generator, here I'm calling the dogenerateClass

I tried with argument :
doGenerateJavaClass(

myEmittersCustom.getPropertySourceEmitter()/*newXpandEmitter ( "xpt::propsheet::PropertySource::Class")*/,
"org.ow2.jasmine.design.model.jonas.diagram.sheet",
"PropertySourceExtended",
myDiagram);
}

This exception is thrown by Eclipse while generating :

It may be other thing to do but what? Do I declare the path to the

Hello Aurelien,

Looks like specified template was not found by code generation process.
You've used xpt::propsheet::PropertySource::Class template for GenDiagram
input.
This means there should be xpt/propsheet/PropertySource.xpt file with appropriate
definition in one of the template roots.
By default GMF generator load all the templates from GMF plugins (you probably
can not add your template there) + customized templates from the "template
directory" (specified by corresponding property of GenEditorGenerator) if
GenEditorGenerator.Dynamic template property was set to true.

So, can you please check that:
- GenEditorGenerator.template directory = "/<projectName>/<templateDirectoryName>"
- GenEditorGenerator.dynamic template = "true"
- xpt/propsheet/PropertySource.xpt is available in /<projectName>/<templateDirectoryName>
folder.
- there is corresponding definition inside this template file.

done for this 2 things (and i'm sure it works because an existing and
changed templates is used)

right too

> - there is corresponding definition inside this template file.

the definiton :
«DEFINE Class FOR gmfgen::GenCustomPropertyTab»
«EXPAND xpt::Common::copyright FOR sheet.editorGen-»
package «sheet.packageName»;

«EXPAND xpt::Common::generatedClassComment»
public class PropertySourceExtended extends
org.eclipse.emf.edit.ui.provider.PropertySource implements
org.eclipse.ui.views.properties.IPropertySource{
«EXPAND PropertySourceExtendedConstructor»
«EXPAND createPropertyDescriptorMethod»
}
«ENDDEFINE»

[...]


I use GMF SDK 2.1.3, not supported in this version?

Hello Aurelien,

> the definiton :
> «DEFINE Class FOR gmfgen::GenCustomPropertyTab»
This definition is not one you are calling (there should be «DEFINE Class
FOR gmfgen::GenDiagram» to satisfy used parameters).

You have to either create «DEFINE Class FOR gmfgen::GenDiagram» or call doGenerateJavaClass
for gmfgen::GenCustomPropertyTab (use different input object as a last parameter
in doGenerateJavaClass method call).

Instead of:
doGenerateJavaClass(myEmittersCustom.getPropertySourceEmitte r(), "org.ow2.jasmine.design.model.jonas.diagram.sheet",
"PropertySourceExtended", myDiagram);

You have to use:
doGenerateJavaClass(myEmittersCustom.getPropertySourceEmitte r(), "org.ow2.jasmine.design.model.jonas.diagram.sheet",
"PropertySourceExtended", selectCustomPropertyTabs(myDiagram.getEditorGen().getPropert ySheet().getTabs()));

I've tried to use a different input object :
«DEFINE Class FOR gmfgen::GenDiagram»
«EXPAND xpt::Common::copyright FOR sheet.editorGen-»
package «sheet.packageName»;

«EXPAND xpt::Common::generatedClassComment»
public class PropertySourceExtended extends
org.eclipse.emf.edit.ui.provider.PropertySource implements
org.eclipse.ui.views.properties.IPropertySource{
«EXPAND PropertySourceExtendedConstructor»
«EXPAND createPropertyDescriptorMethod»
}
«ENDDEFINE»


with error :

Exception (No Definition xpt::propsheet::PropertySource::Class for
GenDiagram could be found!) while generating code


or call

I also tried something like that :

private Object selectCustomPropertyTabs(EList<GenPropertyTab> tabs) {
for (GenPropertyTab tab :tabs) {
if(tab instanceof GenCustomPropertyTab) {
return tab;
}
}
return null;
}

with :

«DEFINE Class FOR gmfgen::GenCustomPropertyTab»
«EXPAND xpt::Common::copyright FOR sheet.editorGen-»
package «sheet.packageName»;

«EXPAND xpt::Common::generatedClassComment»
public class PropertySourceExtended extends
org.eclipse.emf.edit.ui.provider.PropertySource implements
org.eclipse.ui.views.properties.IPropertySource{
«EXPAND PropertySourceExtendedConstructor»
«EXPAND createPropertyDescriptorMethod»
}
«ENDDEFINE»


with error :
Exception (No Definition xpt::propsheet::PropertySource::Class for
GenCustomPropertyTab could be found!) while generating code

Hello Aurelien,

Do you have org.eclipse.gmf.codegen plugin (with gmfgen.ecore model inside)
in your workspace? If yes - try closing this plugin + restarting eclipse
+ executing generate code action again.

:-) Nice to see it's solved.
Few words about this problem - it's rather frequent with current state of
EMF meta-model handling. We are trying to load EMF meta-model (gmfgen.emf)
from the workspace-located file to get latest state from there and use it
in xpand, but sometimes same meta-model can be loaded from the platform and
used by EMF then you load model file (yourmodel.gmfgen) in this case same
meta-classes (gmfgen::Diagram) will be loaded twice and will not be properly
matched in an engine.

As I said, this is not so frequent problem and you usually suffer from it
then you are doing some “advanced” GMF development… So, for now the workaround
is to deploy meta-model to the platform, remove it from the workspace and
let it work as you did.
