get-pass🔗ℹ

This package was inspired by Python’s getpass module.

procedure (get-pass [prompt #:in in #:out out]) → string?

prompt : string? = "password: "

in : input-port? = (current-input-port)

out : output-port? = (current-output-port)

Displays prompt on out. Accepts input on in without echoing input.

Using the below code in get-a-password.rkt

#lang racket

(require get-pass)

(define pass (get-pass "What's your password? "))

(newline)

(displayln (string-append "Your password is " pass))

will result in the following at the terminal if 1234 is entered at the prompt.

$ racket get-a-password.rkt

What's your password?              # "1234" is entered at the prompt, but it is not displayed!

Your password is 1234
