Demo Example

This example demonstrates the fundamental features of JSSON in a single, practical configuration file.

The JSSON

// User configuration
user {
name = João
age = 20
admin = true
roles = [ "admin", "editor" ]

config {
  theme = dark
  language = pt-BR
  notifications = true
}

preferences {
  fontSize = 14
  lineHeight = 1.5
  autoSave = true
}
}

The JSON Output

{
"user": {
  "name": "João",
  "age": 20,
  "admin": true,
  "roles": ["admin", "editor"],
  "config": {
    "theme": "dark",
    "language": "pt-BR",
    "notifications": true
  },
  "preferences": {
    "fontSize": 14,
    "lineHeight": 1.5,
    "autoSave": true
  }
}
}

What This Demonstrates

✅ Simple Assignments

name = João
age = 20

No quotes needed for simple values!

✅ Booleans

admin = true
notifications = true
autoSave = true

Native boolean support.

✅ Arrays

roles = [ "admin", "editor" ]

Mix quoted and unquoted values as needed.

✅ Nested Objects

user {
  config {
    theme = dark
  }
}

Clean, readable nesting without JSON ceremony.

✅ Comments

// User configuration

Document your configs!

✅ Mixed Data Types

fontSize = 14        // Number
lineHeight = 1.5     // Float
autoSave = true      // Boolean
theme = dark         // String

All JSON types supported.

Try It Yourself!

1. Save the JSSON code above to demo.jsson
2. Run: jsson -i demo.jsson -o demo.json
3. Open demo.json to see the result!

Variations to Try

Add More Nesting

user {
profile {
  personal {
    name = João
    age = 20
  }
  professional {
    title = "Developer"
    company = "Tech Corp"
  }
}
}

Add Arrays of Objects

user {
name = João
socialMedia = [
  { platform = twitter, handle = "@joao" },
  { platform = github, handle = "joaodev" }
]
}

Add More Arrays

user {
name = João
skills = [ JavaScript, Python, Go ]
hobbies = [ coding, reading, gaming ]
languages = [ Portuguese, English, Spanish ]
}
