Re: user actions

[Lionel Villard]

Here an example:

void UnaryExpr() #UnaryExpr(cond) :
{boolean cond=false;}
{
  (<Minus>
              {cond=true; jjtThis.processToken(token);}
             #Minus(true) | <Plus>
              {cond=true; jjtThis.processToken(token);}
             #Plus(true))* UnionExpr()
}

The "boolean cond=false" statement I know how to generate it by modifying
the action-exprProduction template.

But for the other ones (cond=true;), it's more complicated.

Lionel, can you give a concrete example of what you want to do?

There are ways to have a derived stylesheet to add actions.
