delphin.mrs.prolog

Serialization functions for the Prolog format.

Example

>>> from delphin.interfaces import rest
>>> from delphin.mrs import prolog
>>> response = rest.parse('The dog sleeps soundly.', params={'mrs':'json'})
>>> print(prolog.dumps([response.result(0).mrs()], pretty_print=True))

delphin.mrs.prolog.dump(destination, ms, single=False, pretty_print=False, **kwargs)

Serialize Xmrs objects to the Prolog representation and write to a file.

Parameters:

• destination – filename or file object where data will be written
• ms – an iterator of Xmrs objects to serialize (unless the single option is True)
• single – if True, treat ms as a single Xmrs object instead of as an iterator
• pretty_print – if True, add newlines and indentation

delphin.mrs.prolog.dumps(ms, single=False, pretty_print=False, **kwargs)

Serialize an Xmrs object to the Prolog representation

Parameters:

• ms – an iterator of Xmrs objects to serialize (unless the single option is True)
• single – if True, treat ms as a single Xmrs object instead of as an iterator
• pretty_print – if True, add newlines and indentation

Returns:

the Prolog string representation of a corpus of Xmrs
