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.
CLIP is a Clipper/XBase compatible compiler with initial support other xBase dialects. It features support for international languages and character sets. It also features OOP, a multiplatform GUI based on GTK/GTKextra, all SIX/Comix features (including hypertext indexing), SQL and ODBC drivers, a C-API for third-party developers, a few wrappers for popular libraries (such as BZIP, GZIP, GD, Crypto, and Fcgi), a multitasking client and application server based on TCP/IP sockets, object data base utilities, and a functions library.
newfile generates "starting-out" files using a full featured template preprocessor. It can also generate trees of files, for example, a FreeBSD port or a project using automake and autoconf. A user can add their own template files and directories to those supplied with the package. It includes templates for making "empty" files for Ruby, make, shell, C, C++, C & C++ headers, and more.
Java+ is a Java preprocessor that adds its features to any Java compiler. It has long, multi-line strings with executable inclusions like Perl or Ruby, optionally segregates Java+ strings into ResourceBundle files, eliminates the need for JSP or ASP and their implied need for Java compilers on deployment servers (a security concern), and adds absolutely no overhead in either space or time. There are graphical and command line interfaces, and a simple, general, and recursive string syntax.
Stunnix Perl-Obfus is a unique solution for protecting your valuable intellectual property from possible Perl source code piracy/studying/rework. It's an advanced and extremely reliable obfuscator for the Perl source code. It converts the Perl source files (.pl and .pm) into highly mangled and obfuscated forms, making them extremely difficult to study, analyse, reuse, or re-work for competitors or customers, while fully retaining functionality of the original source code. It's not a compiler to machine code, and the obfuscated form will still be the usual Perl source code, and so will work on all platforms the original source worked on.
prtpacker (Portable Resource Tree Packer, pronounced PIRT-Packer) is a tool for creating C or C++ source code from external program resources such as images, text, or data. These resources can be arranged in a tree structure much like a typical file system. After compiling and linking the resulting source code you can access the resource tree from within your software through a simple API. Be aware that all resources stay in memory and cannot be easily deallocated.
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.
rfc2mib is a short Tcl script which may be used to extract MIB (Management Information Base), PIB (Policy Information Base), and ASN.1 modules from an RFC document. Unlike most extractors, this script is smart enough to recognize ASN.1-style comments prior to or within the module header. It also recognizes the use of the "TagDefaults" part of the module header (not used by MIB modules), module headers that are broken across multiple lines, and macro definitions.
