groovydsl - Groovy DSL with IDE support for completion -

i in need of dsl has known structure , lot of only known @ runtime structure.

for eg:

test "name goes here"{   description : """ description """   create user {     id : 1     fn : """ x """     ln : """ y """   }   assert user.name == "x"   delete user {      id = 1   }   user1 = user (1)   assert user1 == null } 

in above snippet, keywords test, create, get, delete etc known during development of dsl/tooling. but, when user invokes content assist after create. want download schema files (rather, have downloaded schema first step of processing , cache schema) , offer entities, of user 1 of entities. , when user invokes content assist properties, again entity definition , offer fn, ln etc possible entries there.

is doable groovy , gdsl? thank you
