This project maintains and develops a Fortran parser called fparser2 written purely in Python which supports Fortran 2003 and some Fortran 2008. A legacy parser fparser1 is also available but is not supported. The parsers were originally part of the f2py project by Pearu Peterson.
fparser accepts declarations with incompatible attributes e.g.:
INTEGER, PARAMETER, SAVE :: l1 = 1INTEGER, PARAMETER, INTENT(IN) :: l1 = 1INTEGER, PARAMETER, ALLOCATABLE :: l1 = 1INTEGER, INTENT(INOUT), SAVE :: l1INTEGER, INTENT(IN), INTENT(OUT) :: l1
But any of these are valid Fortran. PSyclone now has checks for these issues, but this could be reported earlier by fparser.
