Strings

Strings are an important part of programming and are used in many high-level programming languages. A string is a combination of alphabetical letters, numbers, and other symbols.

Declaring String

Strings can be declared in numerous ways however the most commonly used are by using double quotes(") and single quotes(').

local str = "EdenRose"
local user = 'EdenRose#1968'

Multi-line String

A Multi-line string can be declared by using double brackets ([[)

local str = [[Helpers of Rodevs are very skilled.
They help a lot in development channels.]]

local str2 = [[Helpers are the pride of Rodevs.
They spend their free time helping out others. :) ]]

Concatenation

Concatenation is as method by using which we can combine two strings, for doing so we use ".." between both the strings.

local str1 = "I am "
local str2 = "EdenRose"
print(str1..str2)

I am EdenRose

String Escaping

In a string declared with (") or ('), You can produce almost any character using (\). It can be used in many ways such as having quotes inside a string without disturbing it, printing in a new line, etc.

print("Greetings \"Rodevs\"")
print("First line \nSecond line)

Greetings "Rodevs"
First line
Second line

Arithmetic With Strings

When using arithmetic operators between strings, Lua tends to convert the string into a number.

print("7" + "22")
print("17" - 4)

29
13

Conversion

A string can be converted into a number by simply using tonumber(), a global function of Lua.

print(tonumber("78")) 
print(tonumber("hola"))

78
nil

Similarly, a number can also be converted into a string by the function tostring()

print(tostring(78))

78
