ForUtils is a package of Fortran classes and convenience functions for Fortran 2003/2008 programs. The utilities comprise these areas:
- ArrayUtils - Find (minimal/maximal) index of an element in an array.
- FileUtils - Classes for handling file access, python-like loadtxt/savetxt functions
- IniObjects - Read/Write name=value configuration files with inheritance, array and default value support.
- MatrixUtils - Read/Write matrices and interface to some BLAS/LAPACK routines.
- MiscUtils - Utility functions for optional arguments.
- MpiUtils - Wrappers for MPI-routines to compile with(out) MPI library.
- ObjectLists - Lists of arbitrary objects including specializations for vectors.
- RandUtils - Some functions to generate random numbers.
- RangeUtils - Maintain sets of equally spaced intervals, e.g. for integration ranges.
- StringUtils - Utilities for strings, like concat of distinct types a.s.o.

Clone this git repository:
$ git clone https://github.com/cmbant/forutils
Compile:
$ make all
This generates the subdirectories Debug and Release and when an MPI library is available also DebugMPI and ReleaseMPI. Each directory contains a libforutils.a archive, which can be used directly for static linking on the compiler command line by giving the absolute filename:
forutils/<RTYPE>/libforutils.a
or by specifying it as a library:
-Lforutils/<RTYPE> -lforutils
Specify one of Debug, DebugMPI, Release, or ReleaseMPI for <RTYPE>. The Debug release types contain debug symbols and use no optimization, while the Release types use a reasonable level of optimization.
- Fortran 2008 compatible compiler - E.g., ifort 14+, gfortran 6 or higher.
- MPI library - Only when you want the MpiUtils fully functional. Without an MPI library MpiUtils compile, but the functions are merely no-ops and the makefile target DebugMPI and ReleaseMPI can not be built.
