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.
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.
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.
Dia2Postgres is a Perl script that can be used to convert Dia diagrams into PostgreSQL scripts or PHP mirror classes which can add, update, and modify table entries automatically. It has support for inheritance, simple references (limited to a single field), and a fake enum type which creates a table.
Doublecpp is a preprocessor for C++ that handles a new linguistic construct for defining branches of a multi-method. The "right" branch of such a method will be selected dynamically at run-time according to the actual type of the object on which the method is invoked, and to the actual type of the first argument: double dispatch. This basically implements dynamic overloading in C++.
WriteTarget is a universal text generator based on Bash text substitution. It can be used to generate text in any programming or markup language. The generator does not define its own language; it rather defines several functions, making it possible to use Bash for creating simple or sophisticated templates.
h2incn tries to directly convert C/C++ headers to Nasm-style include files, and can be used in a makefile. It is useful if you want to use the same structures or external variable declarations in C and assembler code, and you don't want to use two separate files and update both each time you change something. It is written in a mix of C and C++ code. It currently works for simple files.
