Fommons (Fortran Commons) is a collection of common low level components to support XFunit, FTL and Frypto.

Fommons encompasses the following Fortran modules:

• m_object: base building object providing low-level services to derived classes (hash, equality).
• m_string: dynamci character string, compatible with the Fortarn character type.
• m_file_handler: integrated management of file handling (open, close, access, read/write, ...).
• m_iso8601_date, m_iso8601_time, m_iso8601_datetime: management of date/time according to the ISO8601 convention.
• m_msg, m_messages: error handling
• m_path: Management of path (file and directory) strings.
• m_util_convert: Basic conversion amond different intrinsic data types.
• m_xml, m_xml_attribute,m_xml_encoder,m_xml_writer, m_xml_writer_settings: support for the generation of XML documents

Like the other libraries in the collection, XFunit depends on Fommons. At the same time, Fommons depens on XFunit for its unit testing. The aparent circular dependency is not such taking into account.

• The Fommons library can be build indenpendently of any other library.
• The XFunit library depends on on Fommons, but only in the library, not on the unit tests.
• The Fommons unit tests are build from the Fommons unit test sources and the XFunit and Fommons libraries.
• The Xfunit unit tests are build from the XFunit unit test sources and the XFunit and Fommons libraries.

In both Windows and Linux deploy the Fommons and XFunit from the same root directory

• Windows: Projects/Fommons and Projects/XFunit. The .sln files are prepared for this configuration.
• Linux: Projects/fommons and Projects/xfunit. The gmake files are prepared for this configuration (mind the lowercase for the library folder names).

Fommons has been tested with Intel Fortran 19 (or higher) and gfortran 9.4 (or higher).

The tests provided along with the Fommons librariy are written using XFunit.

Fommons is provided with a Visual Studio 2019 configured solution that allows building and testing the entire suite. The solution provides a C# project that integrates the unit test in Fortran with the unit test detection feature of Visual Studio. This allows the execution of all unit tests from the Test Explorer menu.

Create the environment variable XFUNIT_ROOT_DIR=$(ProjectDir).. for each unit testing project to store the test output (.jxml file) in the utest directory. This configuration depends on the windows user in file unit_m_xfunit_<functionname>.vfproj.<windows user>.user

Fommons is provided with gmake makefiles to build and test the entire suite. To build the Fommons library and use modules files execute the following command in the src directory

gmake libs

To build the Fommons library, use modules files and unit tests execute the following command in the src directory

gmake all

To execute the unit tests execute the following command in the src or utest directory

gmake units

The default compiler is gfortran but can be overridden from the command line to use Intel Fortran

gmake F90COMP=ifort

The ifort or gfortran commands must be in the execution path. Alternatively, the makefile can be edited to provide the full path to the compiler. Compiler options are automatically selected for the active compiler; only Debug configuration is provided in the make files.

This readme page is the main user documentation. In addition, documentation generated with FORD and Doxygen can be found in the documentation directory
