Swift Command Line Tool - Read multiple lines

Question

I know the readLine() method, but if copy paste a text with more than one lines, only the first line will be retrieved.

I would like to retrieve all the text that the user copy pastes.

Is it possible ?

Answer 1

You can call readLine() in a loop and exit the loop in a predefined way

var input: [String] = []

print("Enter text, finish by entering Q")
while let line = readLine(strippingNewline: true) {
    if line.lowercased() == "q" { break }
    input.append(line)
}

print(input)

Example

Enter text, finish by entering Q
a
b
c
q
["a", "b", "c"]
Program ended with exit code: 0
