Data Types

SamaLang inherits all data types from Lua. Since SamaLang transpiles directly to Lua, every Lua data type is available.

Numbers

SamaLang uses floating-point numbers (double precision) for all numeric values.

ada umur = 25
ada tinggi = 170.5
ada negatif = -10

tulis(umur)
tulis(tinggi)

Strings

Strings are sequences of characters enclosed in double quotes.

ada nama = "SamaLang"
ada sapa = "Halo, Dunia!"

tulis(nama)
tulis(sapa)

String concatenation uses the .. operator:

ada nama = "Sama"
ada bahasa = "Lang"
ada gabung = nama .. bahasa

tulis(gabung) -- Output: SamaLang

Booleans

SamaLang has two boolean values: tutu (true) and siong (false).

ada aktif = tutu
ada kosong = siong

lamen aktif tres
    tulis("Aktif!")
jure_mo

Nil

The nda_isi keyword represents the absence of a value (equivalent to Lua’s nil).

ada data = nda_isi

lamen data == nda_isi tres
    tulis("Tidak ada data")
jure_mo

Tables

Tables are SamaLang’s primary data structure. They can be used as arrays, dictionaries, or objects.

-- Array
ada buah = {"apel", "mangga", "jeruk"}
tulis(buah[1]) -- Output: apel

-- Dictionary
ada mahasiswa = {
    nama = "Ahmad",
    umur = 20,
    jurusan = "Teknik"
}

tulis(mahasiswa.nama)

See Tables for more details.

Type Checking

Use the type() function to check a value’s type:

ada x = 42
tulis(type(x)) -- Output: number

ada s = "hello"
tulis(type(s)) -- Output: string

Summary

Type	Example	Lua Equivalent
Number	42, 3.14	number
String	"text"	string
Boolean	tutu, siong	boolean
Nil	nda_isi	nil
Table	{1, 2, 3}	table
Function	fungsi ... jure_mo	function
