Strings

Strings in SamaLang are sequences of characters, identical to Lua strings.

Creating Strings

Strings are enclosed in double quotes:

ada sapa = "Halo, Dunia!"
ada kosong = ""

String Concatenation

Use .. to join strings:

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

tulis(gabung) -- Output: SamaLang

Mix strings with numbers using tostring():

ada umur = 20
ada pesan = "Umur saya " .. tostring(umur) .. " tahun"
tulis(pesan)

String Length

Use # to get the length:

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

Common String Functions

Function	Description	Example
string.len(s)	Get length	string.len("halo") → 4
string.upper(s)	Convert to uppercase	string.upper("halo") → "HALO"
string.lower(s)	Convert to lowercase	string.lower("HALO") → "halo"
string.sub(s, i, j)	Extract substring	string.sub("halo", 1, 2) → "ha"
string.find(s, pattern)	Find pattern	string.find("halo", "lo") → 3, 4
string.rep(s, n)	Repeat string	string.rep("ha", 3) → "hahaha"
string.reverse(s)	Reverse string	string.reverse("halo") → "olah"
string.format(fmt, ...)	Format string	string.format("Umur: %d", 20)
string.gsub(s, pat, rep)	Replace pattern	string.gsub("halo", "l", "r") → "haro"

ada nama = "samalang"

tulis(string.upper(nama)) -- Output: SAMALANG
tulis(string.sub(nama, 1, 4)) -- Output: sama
tulis(string.rep("ha", 3)) -- Output: hahaha

Escape Sequences

Sequence	Description
\n	Newline
\t	Tab
\\	Backslash
\"	Double quote

tulis("Baris pertama\nBaris kedua")

Multi-line Strings

Use double square brackets for multi-line strings:

ada puisi = [[
Budaya adalah akar
Bahasa adalah jiwa
Kode adalah masa depan
]]

tulis(puisi)

String Comparison

Strings are compared lexicographically (alphabetically):

lamen "abc" < "abd" tres
    tulis("abc lebih kecil") -- This runs
jure_mo

lamen "abc" == "abc" tres
    tulis("Sama!") -- This runs
jure_mo

Type Checking

ada s = "SamaLang"
tulis(type(s)) -- Output: string
tulis(type(42)) -- Output: number
