Getting information from a user in Lua

How can I get user input in Lua (e.g. scanfin C)?
For example, a program asks the user for its name, then it writes down its name, then the program displays its name.

Use io.read () Beware that the function can be configured with various parameters. Here are some examples.

 s = io.read("*n") -- read a number
 s = io.read("*l") -- read a line (default when no parameter is given)
 s = io.read("*a") -- read the complete stdin
 s = io.read(7) -- read 7 characters from stdin
 x,y = io.read(7,12) -- read 7 and 12 characters from stdin and assign them to x and y
 a,b = io.read("*n","*n") -- read two numbers and assign them to a and b

The simplest input can be obtained with io.read(). This will read one line from standard input (usually a keyboard, but can be redirected, for example, from a file).

You can use it as follows:

io.write('Hello, what is your name? ')
local name = io.read()
io.write('Nice to meet you, ', name, '!\n')

io.read() io.input():read(), io.write() io.output():write(). API read() .

, io.write() , , print().
