math/spar 0.5.10_7 FreeBSD

Spar is a modular math parser that comes with a fully featured text frontend, something like an interactive calculator. It also provides a simple but complete API for C/C++ programmers. This API provide a complete interface to a top down parser that supports: variables, constants, functions, modules and a libc based math library. This math library overrides standard functions with a "custom" version (such as. deg, rad auto conversion, infinite symbol, function domain...).

Spar, can be easily extended with modules. A module is a "user" extensions, written in C/C++, to the basic features of the Simple Parser. Here you can find the module definition: is a C structure that contains only few data member: - module name - module version - module description - a pointer to the module main function

The modules are loaded at run-time by the module loader (that is a high level layer of the module manager): you can load your modules, simply, coping theirs paths into the .spar_modules (or any other file, with the -c option).
