Compiler Construction Tools

1. On-line documentation is available for the following compiler tools:
   • Scanner generators for C/C++: Flex (in HTML), Flex (gzipped PostScript). Lex (PostScript)
   • Parser generators for C/C++: Bison (in HTML), Bison (gzipped PostScript), Yacc (gzipped PostScript)
2. Available scanner generators for Java:
   • JLex, a scanner generator for Java, very similar to Lex.
   • JFLex, flex for Java.
3. Available parser generators for Java:
   • CUP, a parser generator for Java, very similar to YACC.
   • BYACC/J, a different version of Berkeley YACC for Java. It is an extension of the standard YACC (a -j flag has been added to generate Java code).
4. Other compiler tools:
   • JavaCC, a parser generator for Java, including scanner generator and parser generator. Input specifications are different than those suitable for Lex/YACC. Also, unlike YACC, JavaCC generates a top-down parser.
   • ANTLR, a set of language translation tools (formerly PCCTS). Includes scanner/parser generators for C, C++, and Java.
