YAML

WorkInProgress

YAML (YAML Ain’t Markup Language) is a data interchange format, with syntax based on Python’s 🗒️ indentation style. Instead of using {curly braces} (like JSON 🗒️), or HTML-like <tags> (like XML), YAML uses whitespace characters like indentation to indicate nesting.

YAML is often used in configuration files, internet messaging, object persistence, and data auditing/visualization.

Syntax

• YAML files use the file extensions .yml or .yaml
• Items are made up of Key Value Pairs, separated with a :colon, and a space
• Values can be integers, strings, arrays/lists, or objects/dictionaries
• JSON-style [brackets] and {curly braces} can be used, but are not necessary
• List members begin with a -hyphen, with 1 list item per line
• Comments are supported, and made with a #hash symbol
• "quotes" around most strings are not necessary
• For full list of advanced features, see the latest Spec Document 🌐 from yaml.org
