How to add content to a TemplateFragment via Open API?
I am able to create and add a TemplateDeclaration to the generators. I also figured to place my actual content in the context of a TemplateFragment . Basically I tried to reproduce the following outcome (see image "desired outcome").
My question is: What is the right approach to reproduce the result shown in the following image?
(Image: desired outcome)
My code so far creates another outcome (see image at the bottom):
(Image: actual outcome)
Thanks in advance!
Cheers,

My code so far creates another outcome (see image at the bottom):
⋮ // create template declaration node<TemplateDeclaration> jaTemplate = new node<TemplateDeclaration>(); jaTemplate.name = "reduce_JointAngles"; jaTemplate.applicableConcept.set(stub); // create the template fragment TF node<TemplateFragment> tf = new node<TemplateFragment>(); // create inner element node<XmlElement> element = new node<XmlElement>(); element.tagName = "data"; // add element to TF tf.contextNodeQuery.set(element); ⋮

TemplateFragment is a node attribute (annotation) and so is added though the .@ syntax to decorate other nodes. Generator macros are also macros and you will need to handle them in a similar way.
You can read more on handling attributes at https://confluence.jetbrains.com/display/MPSD32/Commenting+out and https://confluence.jetbrains.com/display/MPSD32/Documentation+comments
So in addition to that I would like to create a $LOOP$ macro. I get stuck while creating the mapped nodes part (as seen in the following image):
Now my problem is to create the DotExpression . How do I access the node parameter and angles variable, which is a child of the associated Concept :
My code so far:
// create the source node query node<SourceSubstituteMacro_SourceNodesQuery> loopQuery = new node<SourceSubstituteMacro_SourceNodesQuery>(); ⋮ // create statements and stuff ⋮ // create the DotExpression node<DotExpression> dotExp = new node<DotExpression>(); // trying to access the node operand and operation??? dotExp.operand.set(loopQuery.getParameters() .findFirst({~it => it.name.equalsIgnoreCase("TemplateFunctionParameter_sourceNode"); })); ??? dotExp.operation ???What do I have to do, in order to make it work, and what would be the right way to do it properly?

You can find out the actual concept by looking at the "node.angles" expression in your first screen-shot and observe the concept in the Inspector window or highlight the line and opening it in Node Explorer (Alt + F12).
Also, you may use quotations to build parts of AST in a more convenient way.

But I'm still not quite sure how to create the operation and operand for this specific DotExpression ...
// this is the angles field of the concept that needs to be referenced as operation... node<LinkDeclaration> link1 = new node<LinkDeclaration>(); link1.role.set("angles"); link1.metaClass.set(enum member value/LinkMetaclass : aggregation/); link1.target.set(concept/FloatingPointConstant/); link1.sourceCardinality.set(enum member value/Cardinality : 0..n/); ⋮ // query node<SourceSubstituteMacro_SourceNodesQuery> loopQuery = new node<SourceSubstituteMacro_SourceNodesQuery>(); // body node<StatementList> loopBodyStatementList = new node<StatementList>(); // statement node<ExpressionStatement> expStatement = new node<ExpressionStatement>(); // expression node<DotExpression> dotExp = new node<DotExpression>(); // (node.angles) operation (would be angles); set the link from above ??? node<SLinkListAccess> lla = new node<SLinkListAccess>(); lla.link.set(link1); ??? dotExp.operation.set(lla); // (node.angles) operand (would be node)??? dotExp.operand.set(loopQuery.getParameters() .findFirst({~it => it.name.equalsIgnoreCase("TemplateFunctionParameter_sourceNode"); })); ???This is not really working, because the DotExpression is not being shown in the inspector after executing this code. So there seems to be something wrong, but I can't figure what? And how to do it right...
I would like to access the the node parameter from the (genContext, node, operationContext)->sequence<node<>> function.
As you can see in the image below, the operation works properly (see the .angles; on the top right). Only the operand is actually referring to the concept of TemplateFunctionParameter_sourceNode itself.
So my approach seems to be wrong for the operand :
dotExp.operand.set(loopQuery.getParameters() .findFirst({~it => it.name.equalsIgnoreCase("TemplateFunctionParameter_sourceNode"); }));How can I reference the node parameter of the SourceSubstituteMacro_SourceNodesQuery -context as operand ?
