pyyaml: dumping without tags

Question

I have

>>> import yaml
>>> yaml.dump(u\'abc\')
\"!!python/unicode \'abc\'\\n\"

But I want

>>> import         


        

Answer 1

How about this:

def unicode_representer(dumper, uni):
    node = yaml.ScalarNode(tag=u'tag:yaml.org,2002:str', value=uni)
    return node

yaml.add_representer(unicode, unicode_representer)

This seems to make dumping unicode objects work the same as dumping str objects for me (Python 2.6).

In [72]: yaml.dump(u'abc')
Out[72]: 'abc\n...\n'

In [73]: yaml.dump('abc')
Out[73]: 'abc\n...\n'

In [75]: yaml.dump(['abc'])
Out[75]: '[abc]\n'

In [76]: yaml.dump([u'abc'])
Out[76]: '[abc]\n'
