SLIRP is a C code generator, aimed at simplifying the process of creating modules for the S-Lang scripting language. Using it can dramatically reduce the time and effort required to make C, C++, and FORTRAN code callable directly from the S-Lang interpreter.
SLIRP can also generate Makefiles to automate the module build process, as well as pure C bindings for C++ code (cfront mode), or empty (stub) implementations for the interface(s) specified by its input. The code emitted in the latter two cases has no dependencies upon S-Lang whatsoever.
