Structs

Structs are user-defined data types with named fields.

Declaration

Declare a struct by naming it followed by field names in {}:

user {
  name
  age
  email
}

Or on one line:

user { name age email }

No types. dryLang is dynamically typed — fields accept any value.

Instantiation

Create an instance by providing the variable name, struct type, and field values:

user { name age email }

u user {
  name "Zaky"
  age 17
  email "zaky@example.com"
}

Accessing Fields

Use dot notation:

pt u.name     // Zaky
pt u.age      // 17
pt u.email    // zaky@example.com

Or bracket notation:

pt u["name"]    // Zaky

Modifying Fields

u.age = 18
u["email"] = "new@example.com"

Structs in Arrays

player { name score }

players [
  player { name "Zaky" score 100 },
  player { name "Andi" score 85 }
]

// Note: struct instances inside arrays work like maps
// Access via regular array indexing + dot notation:

.lp len(players) {
  pt players[i].name
.}

Under the Hood

Structs are internally represented as maps. A struct instance is a map with field names as keys. This means all map functions work on struct instances:

user { name age }
u user { name "Zaky" age 17 }

pt key(u)     // shows fields
pt len(u)     // 2 (plus __struct__ meta key)

Struct vs Map

Use structs when you want a named type with a fixed set of fields. Use maps when you need dynamic keys.
