Doubt about EGL in ANT [message #524701]

Hi!

I get a doubt about egl ant. I did this:
File: launch.xml

<?xml version="1.0"?>
<project default="main">
	
	<target name="main">
			<epsilon.emf.register file="../metamodels/MM.ecore"/>
			<epsilon.loadModel name="test" type="EMF">
				<parameter name="modelFile" file="../models/test.model"/>
				<parameter name="metamodelUri" value="/metamodel/MM.ecore"/>
				<parameter name="isMetamodelFileBased" value="false"/> 
				<parameter name="readOnLoad" value="false"/>
				<parameter name="storeOnDisposal" value="false"/>
			</epsilon.loadModel>

		<epsilon.egl src="MM2txt.egl">
			<model ref="test"/>
		</epsilon.egl>
	</target>
	
</project>

And executes successfully but no generates the files. I get:
File: MM2txt.egl

[% -- Generate Entities
	TemplateFactory.setOutputRoot('out'); -- outputDir
	var template : Template;
	for(entity in DataModel.allInstances()){
			template := TemplateFactory.load('other.egl');
			template.populate('entity',entity);
			--template.process();
			template.generate(entity+'.txt');
		
	}
%]

File: other.egl

Hello World! File: [%=entity%]

Am i missing somethig?

Thanks.

Hi,

As readonload is set to false, the contents of your model file are not
read, and thus, DataModel.allInstances() returns an empty collection, so
the body of the for loop is never executed. To fix this please set the
value of readonload to true.

Cheers,
Dimitris

Hi again.
I get a problem with EGL.
When i call package.name.replace('.','_') it replace the whole string with the new character Confused

...
But if for instance i write package.name.replace('T','_') it works fine.

Dot character get to be treated different?

Hi,

The first argument of replace is a regular expression and in reg exps .
means any character. Please use \\. instead of .
