parse and stringify for handling YAML encoded data.

Ported from js-yaml v3.13.1.

Use parseAll for parsing multiple documents in a single YAML string.

This package generally supports YAML 1.2.x (latest) and some YAML 1.1 features that are commonly used in the wild.

Supported YAML 1.1 features include:

• Merge type (<< symbol)

Unsupported YAML 1.1 features include:

• Yes, No, On, Off literals for bool type
• Sexagesimal numbers (e.g. 3:25:45)

import { parse, stringify } from "@std/yaml";
import { assertEquals } from "@std/assert";

const data = parse(`
foo: bar
baz:
  - qux
  - quux
`);
assertEquals(data, { foo: "bar", baz: [ "qux", "quux" ] });

const yaml = stringify({ foo: "bar", baz: ["qux", "quux"] });
assertEquals(yaml, `foo: bar
baz:
  - qux
  - quux
`);

Limitations

• binary type is currently not stable.
