Text manipulation

• The Jack parser generator from SunTest labs is a powerful LL(k) parser generator similar to PCCTS. It includes a unicode scanner generator. Available free of charge, but without source code.
• JavaCUP, an LALR parser generator for Java. It is not a yacc rewrite, but is quite robust (into its fifth release on May 22, 1996) and a good bet if you are looking for an LALR Java parser generator.
• jb is a set of programs to massage flex and bison output to Java.
• JavaLex, a lex style lexical compiler for Java. JavaLex is essentially lex rewritten in Java, and produces 7 or 8 bit ascii scanners which run quite fast.
• Pat package is a package to do runtime pattern matching. Provides perl style patterns with backtracking and matching. Ideal for matching runtime patterns in strings, but not fast. It is for non-commercial use only.

Grammars for Java

Caveat emptor! Some of these grammars are fairly old and do not reflect the current language specification. The language specification itself (compressed postscript) comes with a grammar definition.

• SunTest's Jack parser generator contains a Jack specification to parse Java.
• Guavac is a java compiler in C which uses bison/flex to parse code.
• Dmitri Bronnikov's lex/yacc specifications is capable of accepting the JDK 1.0 demos atleast.
• Scott Hudson's yacc/lex specification written around August 1995(?)
• Terence Parr's ANTLR specification written around May 1995(?)
• The Database Research Group at the University of Geneva has a hyperlinked BNF specification of the language grammar, including pretty syntax diagrams.

Bytecode manipulation

• The Sumatra project at the University of Arizona contains a system to translate bytecode to C, uses and implements its own runtime (subset of the 1.02 API at this point.)
• j2c: A bytecode to C translator. It includes its own runtime, and works independent of the sun Java VM.
• Jonathan Meyer's Jasmin assembler uses a nice assembler-like language, and is distributed under the GNU General Public License.
• Javaa, bytecode assembler with an interface similar to javap output. Check the licensing agreement, it seems to restrict use and modification for "research or educational" purposes only.
• Jobe, a java obfuscator is freely available as shareware, but without source code. A license is required for commercial use. Registered users get access to the source code.
• Hanpeter van Vliet's Mocha decompiler generates very readable java source code from bytecode. Mocha is available free of charge, but without source code. Hanpeter also offers Crema, an obfuscator. The "light version" which obfuscates only applications is available free of charge. Hanpeter has passed away.

Language to Java

• Per Bothner's Kawa scheme compiler compiles a large subset of R4RS scheme to java bytecode.
• Chris Laffra's c2j, a C++ to Java translator written in C++. ...translates roughly about 85-95 percent of our code... says the author.
