问题 There's a good example of sorting at the top level, but how would you recurse the sort at all levels? This seems to work: def sort_commentedmap(self, od): res = ruamel.yaml.comments.CommentedMap() for k in sorted(od): res[k] = od[k] if not isinstance(od[k], ruamel.yaml.comments.CommentedSeq): continue for idx, i in enumerate(od[k]): if isinstance(i, str): res[k][int(idx)] = i else: res[k][int(idx)] = self.sort_commentedmap(i) return res Does this look correct? 回答1: In YAML you can have

问题 I'm facing issue with the recursive sort solution proposed here I cannot sort YAML file with anchor and sub-elements. The .pop method call is throwing a KeyError exception. Ex: volvo: anchor_struct: &anchor_struct zzz: val: "bar" aaa: val: "foo" aaa: "Authorization" zzz: 341 anchr_val: &anchor_val famous_val lambo: <<: *anchor_struct mykey: myval: enabled: false anchor_struct: <<: *anchor_struct username: user anchor_val: *anchor_val zzz: zorglub www: web File "orderYaml.py", line 36, in

问题 I am dynamically adding elements in a list in a YAML file using Python and I would like to add a comment alongside each of the elements I am adding. The following are all desired formats: flow_style_example: - [a, b, c] # first list - [d, e] # second list block_style_example: - - a # first list side comment - b - c # second list top comment - - d - e list_of_elements_side_comment: - a # foo - b # bar list_of_elements_top_comment: # comment 1 - a # comment 2 - b For any of the above I have yet

问题 When I do: from ruamel import yaml seq = ["x", "y", "z", "Y", "true", True] print(yaml.dump(seq, version=(1,1))) it gives: %YAML 1.1 --- [x, y, z, Y, 'true', true] but I expected the y and Y to be quoted, because these get loaded back as booleans because this is YAML 1.1. Moreover this bug, indicates this problem is solved. Why is this bug marked as closed, when it still shows this error even on version ruamel.yaml>=0.15.93? 回答1: You are using the unsafe PyYAML compatibility function dump()

问题 I'm trying to use the ruamel.yaml library to process a Yaml document that contains duplicate keys. In this case the duplicate key happens to be a merge key <<: . This is the yaml file, dupe.yml : foo: &ref1 a: 1 bar: &ref2 b: 2 baz: <<: *ref1 <<: *ref2 c: 3 This is my script: import ruamel.yaml yml = ruamel.yaml.YAML() yml.allow_duplicate_keys = True doc = yml.load(open('dupe.yml')) assert doc['baz']['a'] == 1 assert doc['baz']['b'] == 2 assert doc['baz']['c'] == 3 When run, it raises this

问题 Assume I created a @dataclass class Foo , and added a __post_init__ to perform type checking and processing. When I attempt to yaml.load a !Foo object, __post_init__ is not called. from dataclasses import dataclass, fields from ruamel.yaml import yaml_object, YAML yaml = YAML() @yaml_object(yaml) @dataclass class Foo: foo: int bar: int def __post_init__(self): raise Exception for field in fields(self): value = getattr(self, field.name) typ = field.type if not isinstance(value, typ): raise

问题 With the help of yaml.indent(sequence=4, offset=2) the output is correct but there is extra space coming in each line and I know it is due to above indent function. Is there any way to remove the 2 extra spaces from each line(I don't wont to use strip()). Code: import sys import ruamel.yaml data = [{'item': 'Food_eat', 'Food': {'foodNo': 42536216,'type': 'fruit','moreInfo': ['organic']}}] yaml = ruamel.yaml.YAML() yaml.indent(sequence=4, offset=2) yaml.dump(data, sys.stdout) Output of above

问题 I'm creating yaml files from csv's that have a lot of unicode characters in them but I can't seem to get it to dump the unicode without it giving me a Decode Error. I'm using the ruamel.yaml library. UnicodeDecodeError: 'ascii' codec can't decode byte 0xc2 in position 11: ordinal not in range(128) I've tried parsing strings, unicode strings, encoding with "utf-8" nothing seems to work. I've seen a lot of examples that show adding a representer to solve the issue but they all seem to be using

问题 How to preserve indenting in key-value when dumping yaml ? I am using ruamel yaml Code: in_str='''Pets: Cat: Tom Mouse: Jerry Dog: Scooby ''' import ruamel.yaml, sys results = ruamel.yaml.load(in_str, ruamel.yaml.RoundTripLoader, preserve_quotes=True) results['Pets']['Bird']='Tweety' ruamel.yaml.dump(results, sys.stdout, ruamel.yaml.RoundTripDumper, default_flow_style=True,indent=2, block_seq_indent=2) Output : Pets: Cat: Tom Mouse: Jerry Dog: Scooby Bird: Tweety Expected Output: Pets: Cat:
