Package chasm: Information

Chasm is a tool to improve C++ and Fortran 90 interoperability.  Chasm
parses Fortran 90 source code and automatically generates C++ bridging
code that can be used in C++ programs to make calls to Fortran
routines.  It also automatically generates C structs that provide
a bridge to Fortran derived types.  Chasm supplies a C++ array
descriptor class which provides an interface between C and F90
arrays.  This allows arrays to be created in one language and then
passed to and used by the other language.

Chasm works by parsing C++ and Fortran source files and generating an
XML file.  The XML file describes C++ classes, Fortran modules,
user-defined types, functions, and function parameters.  XSLT
stylesheets are used to transform the XML file into bridging code
that is used to call C++ and Fortran routines.

Chasm (version 1.1.0 and later) contains the Fortran, array descriptor
library.  This is a low-level C library used to manipulate Fortran array
descriptors (dope vectors).  It is the only way one can pass F90
assumed-shape arrays and array sections between C and Fortran.  This
library is primarily aimed at interoperability tool developers, rather
than end users.
