| This directory contains a scanner and parser for the Java programming language. |
| |
| You need the parser generator CUP v0.10j (or newer) for the parser to work. |
| Use the Makefile to generate the lexer and parser, or type: |
| |
| jflex unicode.flex |
| jflex java.flex |
| java java_cup.Main -interface < java12.cup |
| javac JavaParser.java TestLexer.java |
| |
| |
| The parser can be tested with: |
| java JavaParser <inputfiles> |
| |
| The scanner (without parser attached) can be test with: |
| java TestLexer <inputfiles> |
| |
| |
| files: |
| |
| unicode.flex |
| JFlex specification for the Unicode preprocessing phase |
| (see section 3.3 of the Java Language Specification). |
| Demonstrates how to implement a FilterReader with JFlex. |
| |
| java.flex |
| JFlex specification for the "real" Java 1.2 lexer. |
| |
| java12.cup |
| CUP specification for the Java 1.2 parser |

| (with small modifications to interface with the Lexer) |
| |
| JavaParser.java |
| a simple main class to run the parser (no other useful output though) |
| |
| TestLexer.java |
| a simple test driver for the scanner, produces debug output |
| |
| lexer-output.good |
| lexer output for input file TestLexer.java for testing |
