Parse names with capital letters

[brey]

I am trying to parse a namelist that includes names with capital letters. E.g.

&config_nml
   input = 'wind.nc' ! wind data
   STEPS = 864
   layout = 8, 16
   visc_NL = 1.0e-4
   use_biharmonic = .false.
/

would return

Namelist([('config_nml',
           Namelist([('input', 'wind.nc'),
                     ('steps', 864),
                     ('layout', [8, 16]),
                     ('visc_nl', 0.0001),
                     ('use_biharmonic', False)]))])

Is there anyway to maintain the capitalization?

The closest to what you are asking for is the f90nml.patch() function, which can modify a namelist in-place. But there are some severe limitations, which comprise about half of the outstanding issues. The original case of the variable also isn't preserved in Python.

The scanner has recently been updated to preserve case as well as whitespace, which is an important step towards what you need, but the grammar would also have to be updated to work with the new tokens. I don't know when that would happen.
