Introduction To YAML

This article explains about YAML.

Purpose

YAML (YAML Ain't Markup Language) is a human-readable data serialization format often used for configuration files and data exchange. It organizes data in a structured, hierarchical manner using indentation, making it simple and easy to read.

Data Format

In YAML, the key-value pair is used to display the data. The key and the value are separated by the semicolon.

name: John
age: 30

Multiline

In YAML, you can write multiline text in two ways.

Literal Style (|)

literal_example: |  
    This is a multiline  
    string written in  
    YAML using the  
    literal style.

Folded Style (>)

folded_example: >  
    This is a multiline string  
    written in YAML using the  
    folded style. Blank lines  
    are preserved.

Arrays

In YAML, arrays are defined in 2 ways.

Using Dash Notation (Block Style)

products:  
      - Laptop  
      - Smartphone  
      - Tablet  
      - Monitor

Using Inline Notation (Flow Style)

products: [Laptop, Smartphone, Tablet, Monitor]

Comments

In YAML, comments are added using the # symbol.

name: John Doe  # This is the user's full name
age: 30         # Age in years
