# $Id$ PortSystem 1.0 name libmatheval version 1.1.8 categories math devel platforms darwin license GPL-3 maintainers mww description in-memory tree representations of mathematical functions long_description GNU libmatheval is comprised of several procedures \ that make it possible to create in-memory tree \ representations of mathematical functions over single \ or multiple variables and later use them to evaluate \ function for specified variable values, to create a \ corresponding tree for function derivatives over a \ specified variable, or to print a textual \ representation of the in-memory tree to a specified \ string. The library supports arbitrary variable names \ in expressions, decimal constants, basic unary and \ binary operators, and elementary mathematical functions. homepage http://www.gnu.org/software/libmatheval/ master_sites gnu checksums md5 02da702f933a9d6554e27d1b33a89b60 \ rmd160 f8b1212984f5b4e50aea0573b0ff9eeaa7537054 \ sha256 a124f14ce125aa76c8f82b806b6097dcc8d59342f0978a02be88491b6dde2320 patchfiles patch-config.h.in.diff depends_build port:guile configure.args --infodir=${prefix}/share/info configure.env-append GUILE=${prefix}/bin/guile GUILE_CONFIG=${prefix}/bin/guile-config GUILE_TOOLS=${prefix}/bin/guile-tools test.run yes test.target check
