CIME.namelist.get_fortran_variable_indices

CIME.namelist.get_fortran_variable_indices(varname, varlen=1, allow_any_len=False)

get indices from a fortran namelist variable as a triplet of minindex, maxindex and step

>>> get_fortran_variable_indices('foo(3)')
(3, 3, 1)
>>> get_fortran_variable_indices('foo(1:2:3)')
(1, 2, 3)
>>> get_fortran_variable_indices('foo(::)', varlen=4)
(1, 4, 1)
>>> get_fortran_variable_indices('foo(::2)', varlen=4)
(1, 4, 2)
>>> get_fortran_variable_indices('foo(::)', allow_any_len=True)
(1, -1, 1)
