How to use the representative in old version (version <= 0.11) for ruamel.yaml
ruamel.yaml.RoundTripRepresenter.add_representer(type(None), represent)
Works great in package version.
0.14.X
How can I use the same functionality in the old version ( <= 0.11 ) of the ruamel.yaml package, or an alternative way to use it in the previous version of the package?
here is an example of my program
def represent(self, data): return self.represent_scalar(u'tag:yaml.org,2002:null', u'NULL') ruamel.yaml.RoundTripRepresenter.add_representer(type(None), represent) data = ruamel.yaml.round_trip_load(input.yaml) ruamel.yaml.round_trip_dump(data, output.yaml)
while working on code getting below error
ruamel.yaml.RoundTripRepresenter.add_representer(type(None), represent_none)\nAttributeError: 'module' object has no attribute 'RoundTripRepresenter'
source share
In older versions ruamel.yaml
RoundTripRepresenter
(defined in representer.py
) was not imported in main.py
and therefore not available through __init__.py
(which does
from ruamel.yaml.main import *
)
Therefore, you just need to import it from source:
from ruamel.yaml.representer import RoundTripRepresenter RoundTripRepresenter.add_representer(type(None), represent)
