hi everyone

I am trying to use xpand to generate a code from an xmi model conform to an metamodels ecore the name of my model is VHDL and the name of my metamodels MetaVHDL
I begin to use xpand but I can't configure the workflow to run the file, if someone explain me how to do, and for more details I can add more. thanks

Hi,

did you have a look at the sample created with the xpand wizard. it does basically exact that for another ecore.

Hi,

i do not really know how to help you. there are the docs with a tutorial, the wizard creates an example.

here is the workflow (Eclipse Xpand 1.0.x - in oAW 4.3.1 the classnames are a bit different)

<?xml version="1.0"?>
<workflow>
	<property name="model" value="my.generator.project/src/Model.xmi" />
	<property name="src-gen" value="src-gen" />
	
	<!-- set up EMF for standalone execution -->
	<bean class="org.eclipse.emf.mwe.utils.StandaloneSetup" >
		<platformUri value=".."/>
	</bean>
	
	<!-- instantiate metamodel -->
	<bean id="mm_emf" class="org.eclipse.xtend.typesystem.emf.EmfRegistryMetaModel"/>

	<!-- load model and store it in slot 'model' -->
	<component class="org.eclipse.emf.mwe.utils.Reader">
		<uri value="platform:/resource/${model}" />
		<modelSlot value="model" />
	</component>

	<!-- check model -->
	<component class="org.eclipse.xtend.check.CheckComponent">
		<metaModel idRef="mm_emf"/>
		<checkFile value="metamodel::Checks" />
		<emfAllChildrenSlot value="model" />
	</component>

	<!--  generate code -->
	<component class="org.eclipse.xpand2.Generator">
		<metaModel idRef="mm_emf"/>
		<expand
			value="template::Template::main FOR model" />
		<outlet path="${src-gen}" >
			<postprocessor class="org.eclipse.xpand2.output.JavaBeautifier" />
		</outlet>
	</component>
</workflow>

it should not be a problem to adapt this to other ecore based metamodels.
the workflow expects the metamodel to be already registered to the registry.
if this is not the case with your metamodel you can simply do this by changing to

	<bean class="org.eclipse.emf.mwe.utils.StandaloneSetup" >
		<platformUri value=".."/>
		<registerEcoreFile value="src/metamodel/metamodel.ecore" />
	</bean>

if you have any specific questions feel free to ask.

Regards,
Christian

Hi,

the reader loads the model in to a map (slot) under the key model
the generator does call with the template::Template::main FOR model" statement
the definition main in the file template/Template.xpt for the type of the model roots type e.g.

<<DEFINE main FOR ModelRootsType>>
<<ENDDEFINE>>

hi
I followed the template for the workflow configuration and I think I can load the model and meta model but I get an error at running, this is the message

10   INFO  WorkflowRunner     - running workflow: genmodels.oaw
10   INFO  WorkflowRunner     -

and my workflow

<workflow>
	<property name="plugin-src" value="src"/>

	<bean class="org.eclipse.mwe.emf.StandaloneSetup">
		<registerEcoreFile value="${plugin-src}/vhdl.ecore" />
	</bean>

		<metaModel id="mm"
			class="org.openarchitectureware.xsd.XSDMetaModel" />
	</component>
	<component class="org.openarchitectureware.xpand2.Generator">
		<metaModel idRef="mm" />
		<expand value="genmodels::Root FOR model" />
		<outlet path="src-gen" />
	</component>
</workflow>

and the xpandfile

«IMPORT vhdl»

«DEFINE Root FOR vhdl::Model»
«FILE "vhdl.txt"»
Name: «name»

«ENDFILE»
«ENDDEFINE»

if you can fixe this problem i will bé very nice
thanks you for everything

Hi,

i have no clue why you are using XMLReader which is for reading XSD Based XML files and not for ecore based xmis

what about simply using a workflow as i posted before?

<?xml version="1.0"?>
<workflow>
	<property name="model" value="my.generator.project/src/vhalams.xmi" />
	<property name="src-gen" value="src-gen" />
	
	<!-- set up EMF for standalone execution -->
	<bean class="org.eclipse.mwe.emf.StandaloneSetup" >
		<platformUri value=".."/>
		<registerEcoreFile value="src/metamodel/vhdl.ecore" />
	</bean>

	<!-- load model and store it in slot 'model' -->
	<component class="org.eclipse.mwe.emf.Reader">
		<uri value="platform:/resource/${model}" />
		<modelSlot value="model" />
	</component>

	<!--  generate code -->
	<component class="org.openarchitectureware.xpand2.Generator">
		<metaModel class="org.eclipse.m2t.type.emf.EmfRegistryMetaModel"/>
		<expand
			value="template::Template::main FOR model" />
		<outlet path="${src-gen}" >
			<postprocessor class="org.openarchitectureware.xpand2.output.JavaBeautifier" />
		</outlet>
	</component>
</workflow>

and then i have no idea how you git that xmi,
if i create one with ecore means it would look like

<?xml version="1.0" encoding="ASCII"?>
<Model xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="vhdl" xsi:schemaLocation="vhdl metamodel/vhdl.ecore" name="exemple">
  <entite name="cell">
    <archi name="cell">
      <function name="operation"/>
      <contraints name="x=x+1"/>
      <composants name="microActuator">
        <portInterne name="port1"/>
      </composants>
      <composants name="microSensor">
        <portInterne name="port2"/>
      </composants>
      <composants name="microController">
        <portInterne name="port3"/>
        <portInterne name="port3"/>
      </composants>
      <connector role="port1" port="port3"/>
      <connector role="port2" port="port4"/>
    </archi>
  </entite>
</Model>

Hi,

i tried to explain this problem to you before:

guess you have this template in a file src/bla/Blubb.xpt

«IMPORT vhdl»

«DEFINE Root FOR vhdl::Model»
«FILE "vhdl.txt"»
Name: «name»

«ENDFILE»
«ENDDEFINE»

then of course you have to call

<expand
			value="bla::Bliubb::Root FOR model" />

I thought a least the error message from the workflow runner should have given you that hint
