Question

I want to write a code in DrRacket that accepts a multiple words from the command prompt and does converts them to a list of string. For eg. if I enter hello how do you do in the prompt, it should convert it into a list ‘(“hello” “how” “do” “you” “do”). Is it possible in DrRacket?

i tried this:
(define inp-lst (read))

On running this code, an input bar is shown in the command promt. but when i enter the above line, the value of inp-lst turns out to be just ‘hello. Can someone help?

Answer 1

As a first step, type your input between quotes, like this:

(define inp-lst (read))
"hello how do you do"

Now, you can create a list of strings doing this:

(regexp-split #px" " inp-lst)
> '("hello" "how" "do" "you" "do")

EDIT :

As has been pointed out in the comments, read-line might be a better alternative:

(define inp-lst (read-line))
(regexp-split #px" " inp-lst)
> '("hello" "how" "do" "you" "do")

Using read-line, you don’t need to surround the typed text with quotes.
