Hi,
I would like to be able to override the file location provided to the import
statement of my DSL. I need the ability to map the path to a different
physical one. Is there a straightforward way to achieve this?
For example, import "linux/server.vml", where the path needs to be
transformed to /{RepoDir}/vml/linux/server.vml.
Thanks
Derek

Hi Derek,
you may even try to simply override resolve() and
perform your transformation on the result of super.resolve().

Sebastian
