Hi all ,

Is it possible install meaning to tab and enter? Let's say i push enter button and begin scoping of a component then i write that components property with tab(indent). When i push enter,scoping of that component should finish so may i use enter instead of curly brackets.i want write a grammar without curly brackets.

For Example:Defined A in the language, b is defined under the A (A'scoping is fineshed when B's scoping is stared)

Element A //started A's scoping
b //b is in the A's scoping
Element B //star B's scoping and A's scoping is finished
c

Best regards;

Hi,

if I understand your question correctly

Model: elements+=Element*;

Element: 'Element' name=ID
  children+=Child*
;

Child: name=ID;

should do what you are looking for in the easy case. Curly brackets are not necessary for "nesting", they only make it much easier in many cases.

If tabulators are significant in your language, it becomes a bit more complicated as white spaces is something Xtext does not care about by default. However, there are examples for languages where indentation plays a role (e.g. http://www.eclipse.org/forums/index.php/mv/msg/174823/556885/)
