[EWL] Accessing model [message #639813]

Hi,

I want to refactor my model utilizing EWL but I'm a little stuck on how to delete model elements. In my ETL files I called deleteElement(obj) on my loaded model, but how can I do that with EWL?

I also realized that I cannot use imports in EWL files, however, this would be a great benefit because I could reuse some of my ETL operations!

The implicit name of the loaded model in EWL is "Model". As such, to
delete an element you can call Model.deleteElement(obj) as usual.

EWL supports importing EOL files - like all other Epsilon languages. If
you have your operations inside a .etl file I'd suggest putting them in
a .eol file and then importing it from both your .etl and .ewl file.
