Example
Demonstrates a common use for string.lower - case-insensitive user input.
-- All keys in this table must be lowercase:
local products = {}
products.apple = "Buy an apple!"
products.banana = "Buy a bunch of bananas!"
products.tomato = "There's also tomatoes."
-- This function is case-insensitive, meaning "APPLE", "apple", and "APPle" are all the same.
function GetProduct( userinput )
return userinput, products[ string.lower( userinput ) ]
end
-- Demonstration:
print( GetProduct( "apple" ) )
print( GetProduct( "Apple" ) )
print( GetProduct( "APPLE" ) )
print()
print( GetProduct( "banana" ) )
print( GetProduct( "BaNaNa" ) )
Output:
apple Buy an apple!
Apple Buy an apple!
APPLE Buy an apple!
