IRPF90 is a Fortran90 preprocessor written in Python for programming using the Implicit Reference to Parameters (IRP) method. It simplifies the development of large fortran codes in the field of scientific high performance computing.
BlockIt provides a Python framework to scan and parse a program file into constituent nested blocks, however defined, forming a block tree of your code and can be used as a mechanism to "extend" in some sense, the underlying programminglanguage.
Pyfort is a tool for creating extensions to the Pythonlanguage with Fortran routines. It supports F77-interfaced routines now, with plans for supporting more of F90 later.
