Code Template - classTag with variable tag name does not work

[StefanBrandmeier]

Hello EA community,

I am trying to evaluate tagged values inside of the code generator of EA.
Using the tagged value substitution macro I try

$tagName = "test"
$tagValue = %classTag:"$tagName"%

Unfortunately the variable $tagName is not evaluated and the $tagValue stays empty.
If I replace the variable with a literal of the tag name then it works.

Is this a bug or a missing feature ?

Thanks for any help

Cheers
Stefan

You could call it a missing feature. The language only supports a string literal in that location, you're asking for a tag with the name "$tagName".

You can achieve the same effect with a call to an add-in: %EXEC_ADD_IN("MyAddIn","GetTag",classGUID,$tagName)%

Hi Eve and thanks for your quick reply !
I was not aware of this macro. I will have to look up how the create the "MyAddIn" ?
Any example you can point me to ?

Checking the documentation I don't see the possibility to code an add-in as a JScript in my script library.
Do I really have to create a DLL in a foreign IDE in order to get this "missing" feature ?

Thanks
Stefan

Yes, and add-in requires a COM compabitible dll.

I have published a tutorial on how to create add-ins and stuff on my website: https://bellekens.com/writing-ea-add-ins/

You can also create a model add-ins.

Hello Eve,

I did manage to find my way into the model add-ins and added some behaviour code, see below.
Can I just code this in JScript for example and use the Add-In with the macro you mentioned above ?

Thanks
Stefan

var elem as EA.Element;
var tag as EA.TaggedValue;
var tags as EA.Collection;
elem = Repository.GetElementByID(elementID)
tags = elem.TaggedValues;
tag = tags.GetByName(tagName);
return tag.Value;
