how to specify to use a name between single quotes in xtext [message #1049434]

I am working on specifying a DSL using XTEXT.

Part of the syntax is that a number of names are between single quotes or double quotes.

Until now I am unsuccessful in achieving this.

What will be the rule in XTEXT for : Process 'my process'

and

"This is my definition" =

What I have tried for the single quote example is:

 Process:
    'Process' '\'' name=ID '\'' ;

but this will give the following error when I compile the .mwe2 file and run as Eclipseapplication: mismatched input ''hello'' expecting '''

Please point me to the right direction to solve this. It must be something trivial, but I cannot seem to solve this...

Hi,

your rule collides with the string rule so you may have to override the string rule not to use single quotes.
btw why dont you simply use name=STRING instead?

OK, thanks for the quick reply.

I am learning XTEXT , so the syntax and constructs and grammar are not yet clear to me. Need to dig into it.

Pointers to information are welcome
