This directory contains an interoperability example for BYacc/J and JFlex | |
(a small calculator) | |
You need the parser generator byacc/j from | |
http://troi.lincom-asg.com/~rjamison/byacc/ | |
for this example to work (version byacc/j 1.1 has been tested). | |
Use the Makefile to generate the lexer and parser. | |
The example can then be started with | |
java Parser | |
files: | |
calc.flex | |
JFlex specification for the lexical part of the arithmetic expressions | |
calc.y | |
BYacc/J specification and main program for the calculator | |
