Question

Lets say I have the code:

str = "foobar"
print "Enter in the letters you would like to match: "
match = gets
# Pseudocode:
str =~ /[match]/

I don’t want to match the whole string: match, I just want to match each of the letters, like:

str =~ /[aeiou]/

would yield the vowels.
How do I make it so I can match the letters the user inputs?

Answer 1

Try this:

match = gets.chomp # cut off that trailing \n
str =~ /[#{match}]/
