Racket (formerly PLT Scheme) is a programming language suitable for implementation tasks ranging from scripting to application development, including GUIs, Web services, etc. It includes the DrRacket programming environment, a virtual machine with a just-in-time compiler, tools for creating stand-alone executables, the Racket Web server, extensive libraries, documentation for both beginners and experts, and more. It supports the creation of new programming languages through a rich, expressive syntax system. Example languages include Typed Racket, ACL2, FrTime, and Lazy Racket.
Unifdef is useful for removing #ifdef'ed lines from a file while otherwise leaving the file alone. You specify which symbols are defined or undefined with -D and -U flags, and unifdef removes the corresponding ifdefs, and the enclosed code if appropriate. It's especially useful for removing those "#ifdef BROKEN" and "#ifdef PRIVATE" clauses from code before you release it. Unifdef acts on #if, #ifdef, #ifndef, #elif, #else, and #endif lines, and it knows only enough about C and C++ to know when one of these is inactive because it is inside a comment or a single or double quote.
Stunnix CXX-Obfus is a code obfuscator for C and C++ source code. It converts source code into highly a mangled form, making it extremely difficult for competitors or customers to study, analyze, reuse, and re-work, while fully retaining functionality of the original code. It has many options to control all aspects of code hiding, and has full support for all syntax constructs. It is designed for multi-file projects with mixed C and C++ source and arbitrary heavy use of the C preprocessor. It includes advanced tools to exclude API symbols from mangling.
Stunnix VBS-Obfus protects your VBScript code from potential analysis, study, or reworking by unwanted parties. It's both an obfuscator and encoder for the VBScript code. It converts the VBScript in raw .vbs files, or in ASP or HTML pages into a highly obfuscated form, making it extremely difficult to study, analyse, or reuse, while fully retaining functionality of the original source code. It optionally adds expiration and hostname checking. It has a lot of options to control all aspects of code hiding, and has full support for all syntax constructs. It is designed to be multi-module aware.
JCPP is a complete, compliant, standalone, pure Java implementation of the C preprocessor. It is intended to be of use to people writing C-style compilers in Java using tools like sablecc, antlr, JLex, CUP, and so forth. It has been used to successfully preprocess much of the source code of the GNU C library.
distcc is a parallel build system that distributes compilation of C/C++/ObjC code across machines on a network. It can be set up in just a few minutes and makes builds up to ten times faster. It does not require machines to share a filesystem or have the same libraries or header files, and installation does not need superuser privileges.
