| [Xtext] implement toString() with the ParseTreeConstructor [message #659244] |

Hi,
I'm wondering if there is a way ((static) utility method or something
like this) for creating a String from a model object according to the
grammar. That is, I want to print out my model elements according to the
grammer, mainly for debugging purposes. In some cases, I do not have an
Xtext text file but only the model elements.
I figure it should be possible to use the generated parse tree
constructor to achieve that, isn't it? (I do not need the formatter).
Before I start digging into the constructor, I was wondering if some
kind of utility class doing exactly this already exists?
Actually, what I want to do is to replace the generated toString()
methods in my model implementation with this grammar like output. Maybe
there is a hidden switch to even enable that? Or do I have to do this
myself, e.g. by implementing a post processor transformation adding the
toString body to the model elements?
Cheers,
Jens

Did you look at Serialization? - it produces text/string from the model.
