parmed.utils.fortranformat.FortranRecordWriter module

class parmed.utils.fortranformat.FortranRecordWriter.FortranRecordWriter(format)

Bases: object

Generate a writer object for FORTRAN format strings

Typical use case …

>>> header_line = FortranRecordWriter('(A15, A15, A15)')
>>> header_line.write(['x', 'y', 'z'])
'              x              y              z'
>>> line = FortranRecordWriter('(3F15.3)')
>>> line.write([1.0, 0.0, 0.5])
'          1.000          0.000          0.500'
>>> line.write([1.1, 0.1, 0.6])
'          1.100          0.100          0.600'

Note: it is best to create a new object for each format, changing the format causes the parser to reevalute the format string which is costly in terms of performance
