Lua pack()

The pack() function takes multiple argument values, then returns a new table.

Syntax

table.pack(value1, value2, ..., valuen)

• value1, value2, ..., valuen: Each argument value will become an element in the new table.

Note: The n field is added when passing arguments to the pack() function where n is the number of elements in the table. This field can called using the dot notation syntax. For example, cars.n will return the number of elements in the cars table. Remember that Lua table elements will begin with index 1, not 0.

Example

The following example uses the pack() function to take multiple argument values like Watermelon, Bananas, Apple, and Oranges to create the table fruit.

fruit = table.pack('Watermelon','Bananas','Apple','Oranges')
print("Table: ",fruit)
print("Fruit number 2:",fruit[2])
print("Total number of fruit: ",fruit.n)
