Take a look at the string_pattern gem project: https://github.com/MarioRuiz/string_pattern

To install it: gem install string_pattern

This is an example of use:

require 'string_pattern'
# four characters. optional: capitals and numbers, required: lower
"4:XN/x/".gen    # aaaa, FF9b, j4em, asdf, ADFt
