This should be a very simple thing - I'm attempting to have my grammar hide

I am writing a grammar for a fairly complex expression language, and in
particular I need to support string concatenation which is performed simply
by separating string literals with a space; and which automatically converts
other expressions to a string if needed to concatenate:
a b - ab

ahhh... just updated my grammar to output templates...
you're right, once you explained it I knew what to look for in other
examples I had worked through.
Now when I'm calling toString on the template that was returned I'm
getting everything that I accumulated while walking my AST.
Now currently
Hi Bart -
Yes, it's a \n, and I thought I told the grammar to set '\n' to a hidden
channel. So, why is it not hidden?

Assuming you mean a new line char, then it _is_ being sent to the HIDDEN
channel as Norman already
Hi Jim,
I think bug is here ... Just only have found this place during debug,

Think in C, where a newline character is represented in code as '\n'.
There are two physical characters between the quotes, but
Hi Bart, thanks very for the quick reply.
I should have made it clear that concatenating is only legal if at least one of
the operands is a string literal - that is where I am having an issue. In other
terms the input
3 3EOF
should cause a syntax error, while
3 3EOF
should not (and evaluates
Don't make the parser trap that error as a syntax error. It is a semantic
error and so you should parser any operand type, then reject the incorrect
types with code.

I have add call reset() for now in the method of generated parser.
