Nested lists seems to be "dumped" incorrectly

Reported by: maksims.juvcenko@… Owned by: xi
Priority: high Component: pyyaml
Severity: major Keywords: List; dump


Problem occurs, when nested list is dumped.

>>> s = {"a": ['aaa','bbb','ccc']}
>>> print yaml.dump(s, default_flow_style=False)
- aaa
- bbb
- ccc

According to specification of YAML 1.1 nested sequence items must have entry token equal to " -" (two spaces and minus symbol), but in reality it lacks entry spaces. This issue creates limitations, when YAML documents are passed between PyYAML and JYaml interpreters.


  • PyYAML version: PyYAML 3.08
  • Python version: 2.5.2

PyYAML output is correct, see, for instance, Examples 10.3 and 10.4 in the specification:  http://yaml.org/spec/1.1/#id931893.
