[news.eclipse.modeling.tmf] Re: [XText] serialize parsed tree to String

[Michael Burkhardt <mib@xxxxxxxxxx>]

Hi Sebastian,


ok, I've got it running, but not in a way I want.

Parsing and serialization are divided into two classes in my implementation. 
Thats the reason why XtextResourceSet.getResource() reports: "resource was not 
registered".


If I merge the methods, I got a different serialization as I hoped for.
I put into the parser a line like this:

 $varname = 5;

after parsing and serializing I got something like that:
======
scripts[0] = Assign {
 variable = 
Variable(name='de.btopia.ghandara.charme.impl.VariableNameImpl@55eb1db2 (name: 
$result)') {
  69: "] = $current ; $message = "square root found" ; } }...":
   -> Variable_IndexAssignment_1_1: Variable.index is not set.
  68: "= $current ; $message = "square root found" ; } } }...":
   -> Variable_PropertyAssignment_2_1: Variable.property is not set.
  }
  value = Expression {
  headTerm = IntegerConst(...
====
OK, I found no easy-to-read code snipplet. Sorry. I can give you much more 
complex examples.

But first, the Injector needs an inject with the registered resources. The use 
cases (parse and serialize) can be made independent from each other. The parsed 
model has all information about the original DSL code. There is no need to store 
resource URIs _OR_ the authority for registration resources is unique in the 
whole system.

But in my case:
How can I reach my simple DSL code line "$varname = 5;" from serialization?


Ciao, Micha
