PyYAML dumper/loader using field descriptions in class comments

pyyaml-typed

Library providing dump and load functions for pyyaml supporting go-yaml-like description of yaml fields as class comments

Dataclasses and named tuples can be used without defining field names. Field in comment for them will override default class field name

Example:

from tyaml import dump

@dataclass
class Something:
    my_fld_1: int
    # or use `yaml:` comment to rename
    field2: str  # yaml: my_fld_2

output = dump([Something(1, "that's"), Something(2, "nice")])

will create yaml:

- my_fld_1: 1
  my_fld_2: "that's"
- my_fld_1: 2
  my_fld_2: "nice"

and in the opposite direction:

from typing import List

from tyaml import load

loaded = load(yml_str, List[Something])
loaded == [Something(1, "that's"), Something(2, "nice")]
