Expression to select all elements in a group

[james-bungard-bjss]

Hi, is there any way to use the !elements <expression> DSL construct to select all members of a group?

I tried element.parent==<group> and element.properties[group]==<group> but both of these result in a No elements found for expression error.

What are you trying to do?

Hi Simon, just trying to avoid repetition in the DSL. I have come across several scenarios where all the elements in a group share a common set of relationships, or I want to apply the same tag to all of them. A contrived example:

consumer = softwareSystem "Consumer"

externalDataProviders = group "External Data Providers" {
    providerA = softwareSystem "Provider A"
    providerB = softwareSystem "Provider B"
    providerC = softwareSystem "Provider C"
}

!elements element.group==externalDataProviders {
    tags "External" "DataProvider"
    -> consumer "Provides data for"
}

Right now I can add a tag manually to each element in the group and use !elements element.tag==... to do the rest, but it would be simpler to just filter by group if that were possible.

Thanks - that's been added; see #351 for details.
