YAML Encoding and Decoding

DotHRB provides functions for converting YAML data. Use these functions to seamlessly transform YAML strings into accessible hashes and vice versa.

Function	Signature	Description
yamldecode	yamldecode(yaml_string) -> hash	Converts a YAML-formatted string into an hash.
yamlencode	yamlencode(hash) -> yaml_string	Converts a programming hash into a compliant YAML string.

string_plain: This is a simple string.
string_quoted: "Quoted strings can use special characters like a colon: and preserve leading/trailing spaces. "
string_literal: |
  This is a literal block scalar.
  It preserves newlines and ignores trailing whitespace.

string_folded: >
  This is a folded block scalar.
  It converts newlines into spaces, making the text flow as a single line, but still wrapping neatly in the editor.
