Exception in yaml.dump() with Dumper and default_style=True, but not with CDumper

Description

Hello,

I meet a reproducible Exception when dumping a python dictionary with default_style=True. This occurs when Dumper=yaml.Dumper, but not with the CDumper.

My setup:

python-yaml, version: 3.09-5 python2.6.6, libyaml-0-2

A simple script to reproduce this exception:


#!/usr/bin/python

import yaml

str_in = """ test:

a: b

"""

d = yaml.load(str_in, Loader=yaml.Loader)

print yaml.dump(d, Dumper=yaml.CDumper) print yaml.dump(d, Dumper=yaml.CDumper, default_style=True) print yaml.dump(d, Dumper=yaml.Dumper) # This line causes an exception print yaml.dump(d, Dumper=yaml.Dumper, default_style=True)


The exception is as follows:

Traceback (most recent call last):

File "./yamlerr.py", line 15, in <module>

print yaml.dump(d, Dumper=yaml.Dumper, default_style=True)

File "/usr/lib/python2.6/dist-packages/yaml/init.py", line 175, in dump

TypeError?: 'in <string>' requires string as left operand, not bool


Thanks in advance for your feedback.

This scenario does not seem valid, as default_style requires to be string, not a boolean.

You might use default_flow_style rather than default_flow_style. However, the problem might be that the CDumper does not seem to honor that parameter.
