I'm a writting an application that make use of 'expressions'
At the moment I can compute the expression. What I want to do is
extract the expression string.
This is so that the application I am writting, simple auto code
generator, can insert the expression string into the code and not the
evaluation of the expression (as it currently does).
I think I want to make use of embedded actions but I can find no
examples of this.
The expression rule I am using has been defined using recursion and
%left / %right / %noassoc directives.
This is NOT homework!
[There's really no easy automated way to do it. Have each token carry its
string representation along and glue the pieces together in each reduction.
Embedded rules wouldn't be useful here. -John]
