The complete symbol approach was deemed to be the right approach for Dlang. Now, the user can return from yylex() an instance of YYParser.Symbol structure, which binds together the TokenKind, the semantic value and the location. Before, the last two were reported separately to the parser. Only the user API is changed, Bisons's internal structure is kept the same. * data/skeletons/d.m4 (struct YYParser.Symbol): New. * data/skeletons/lalr1.d: Change the return value. * doc/bison.texi: Document it. * examples/d/calc/calc.y, examples/d/simple/calc.y: Demonstrate it. * tests/calc.at, tests/scanner.at: Test it.
Examples in D
This directory contains examples of Bison grammar files in D.
You can run make to compile these examples. And make clean to tidy
afterwards.
d/simple.y
The usual calculator.
d/calc.y
A richer implementation of the calculator, with location tracking.
