Hi Roger,
There's currently no support for this. But, how about creating an empty
production where the name of the production encodes the version:
...
Productions
program = version ...;
version = v10;
v10 = ;
Of course, you would need to devise an encoding that conforms to
SableCC's identifier syntax.
Have fun!

I need to be able to track the revision number of my syntax, so that a
user can know what version they are using.
I would like be able to somehow define a string that would
automatically be inserted in the AST of my tree and be able to return
that string. (Basically, I want a node that returns a token to always
appear in the tree, regardless of whether that token *actually* occurs
in the input file that I am parsing)
Is there a good way to do this? I can generate the node in the AST
without any problem, but feeding it the desired string is what I dont
see how to do....
