one file extension, multiple sub-grammars [message #1355860]

A question somewhat similar to stackoverflow.com/questions/16831139/xtext-multiple-files-language

The problem is that DSL sub-dialect is specified using folder/file name, there is no root element, i.e:

recipes/recipe1.txt
borsch = {
some stuff
ingredients = { apple }
}

fruits/fruit1.txt
apple = {
color = { green yellow red }
}

There is no root element to use --> folder/file name is the root element

Is there any way to somehow make xtext pass folder or file name to grammar? So I could write something like:

Model: [if parent_folder="recipes"] Recipe | [if parent_folder="fruits"] Fruit;
Recipe: ...;
Fruit: ...;

Thanks
