I am trying to randomize the echo character in the Highline gem's ask method, but could not get it to work. Did I not do this right?
srand
ask("password: ") { |q| q.echo = ('a'.ord+rand(26)).chr }
The character is randomized for each ask() call, but not each character. The first run will echo the same character, i.e. 'cccc'. The next run will echo 'mmmm', etc.
echo is a variable value used to determine whether to echo output. From the highline source:
# [echo] Can be set to +true+ or +false+ to control whether or not input will
# be echoed back to the user. A setting of +true+ will cause echo to
# match input, but any other true value will be treated as a String to
# echo for each character typed.
Your code (('a'.ord+rand(26)).chr) is being evaluated once per ask, stored in the echo variable within highline, and then printed out for each character entered.
You can't get it to print a different random character per input character without modifying highline.
