YAML Cheatsheet

Overview

• YAML (YAML Ain’t Markup Language) is a human-readable data serialization format.
• It is often used for configuration files, data exchange between languages, and storing data in a structured format.
• YAML files use a .yaml or .yml file extension.

Basic Syntax

• YAML files use indentation to indicate structure.
• Data is represented as key-value pairs, where the key and value are separated by a colon.
• Lists are represented using a hyphen followed by a space.

Example

# Example YAML file

age: 30
address:
  street: 123 Main St
  city: Anytown
  state: CA
  zip: 12345
skills:
  - Ruby
  - Python
  - JavaScript

Data Types

• Scalars: strings, numbers, booleans, null
• Lists: ordered collections of data
• Maps: unordered collections of key-value pairs

Advanced Syntax

• Comments start with a hash (#) and continue to the end of the line.
• Multiline strings can be represented using the pipe (|) character.
• Anchors (&) and aliases (*) can be used to reference the same data in multiple places.
