This directory contains a script that can be used to automatically generate wrappers from C headers provided by the HSL libraries. This is done using Clang.jl. We also have a script to generate the skeleton of wrappers for Fortran functions and subroutines.

Either run julia wrapper.jl directly, or include it and call the main() function. Be sure to activate the project environment in this folder (julia --project), which will install Clang.jl and JuliaFormatter.jl. The main function supports the boolean keyword argument optimized to clear the generated wrappers. You can also call main(library) if you want to generate the wrapper for a specific HSL library. The possible values for library are:

• "all" (default);
• "libhsl";
• "hsl_ma48";
• "hsl_ma57";
• "hsl_ma77";
• "hsl_ma86";
• "hsl_ma87";
• "hsl_ma97";
• "hsl_mc64";
• "hsl_mc68";
• "hsl_mc69";
• "hsl_mc78";
• "hsl_mc79";
• "hsl_mi20";
• "hsl_mi28".

If a package doesn't have a C interface, we are still able to use it in Julia but we need to call the Fortran functions and subroutines. The wrappers for Fortran functions and subroutines can't be easily generated and are generally written by hand but the file analyzer.jl helps to partially generate the wrappers. analyzer.jl is only able to fully generate the wrappers of functions and subroutines written in FORTRAN 77. You just need to provide the path of the libHSL on your computer (libhsl variable) and call main(library). library can be any HSL package available in the libHSL folder.

If a new C interface is available, add an entry for it in the main function of wrapper.jl.
