Operators

SamaLang supports all Lua operators. Since the transpiler only replaces keywords, operators work exactly as they do in Lua.

Arithmetic Operators

Operator	Description	Example
+	Addition	3 + 2 → 5
-	Subtraction	10 - 4 → 6
*	Multiplication	5 * 3 → 15
/	Division	10 / 3 → 3.333...
%	Modulo	10 % 3 → 1
^	Exponent	2 ^ 3 → 8

ada hasil = (10 + 5) * 2
tulis(hasil) -- Output: 30

ada sisa = 17 % 5
tulis(sisa) -- Output: 2

Comparison Operators

Operator	Description
==	Equal to
~=	Not equal to
>	Greater than
<	Less than
>=	Greater than or equal
<=	Less than or equal

ada umur = 20

lamen umur >= 18 tres
    tulis("Dewasa")
jure_mo

Note

SamaLang uses ~= for “not equal” (same as Lua). This differs from many other languages that use !=.

Logical Operators

Operator	Description	Lua Equivalent
no	Logical NOT	not
dan	Logical AND	and
atau	Logical OR	or

ada x = tutu
ada y = siong

-- no (NOT)
lamen no y tres
    tulis("y adalah siong") -- This runs
jure_mo

-- dan (AND)
lamen x dan y tres
    tulis("Keduanya benar") -- This does NOT run
jure_mo

-- atau (OR)
lamen x atau y tres
    tulis("Salah satu benar") -- This runs
jure_mo

String Concatenation

Use .. to join strings together:

ada nama = "Sama"
ada versi = "Lang"
ada gabung = nama .. versi
tulis(gabung) -- Output: SamaLang

Length Operator

Use # to get the length of a string or table:

ada teks = "SamaLang"
tulis(#teks) -- Output: 8

ada buah = {"apel", "mangga", "jeruk"}
tulis(#buah) -- Output: 3

Caution

The # operator is also used as the comment marker in SamaLang. When used before a value, it acts as the length operator. When used at the start of a line (or after whitespace), it starts a comment.

Operator Precedence

From highest to lowest precedence:

1. ^ (exponent)
2. #, unary -, no (NOT)
3. *, /, %
4. +, -
5. .. (concatenation)
6. <, >, <=, >=, ~=, ==
7. dan
8. atau
