Regex: how to match duplicate syllables?

Merry Christmas!

But work goes on :frowning:

Just trying a way to match duplicate syllables.

C = "bcdfghjklmnpqrstvwxyz"
V = "aeiou"

aString =~ /[#{C}][#{V}][#{C}][#{V}]/

should match if the first CV matches the next CV. Hence, "waikiki"
should match on "kiki". And "dodo", "paparazzi" should match too.

Thanks!

Hope this helps:

>> V = "aeiou".freeze
=> "aeiou"
>> C = ("a".."z").to_a.join.gsub(/[#{V}]/, "").freeze
=> "bcdfghjklmnpqrstvwxyz"
>> DBL_SYL = /([#{C}][#{V}])\1/.freeze
=> /([bcdfghjklmnpqrstvwxyz][aeiou])\1/
>> %w{waikiki dodo paparazzi}.each do |test|
?> puts "#{test} => #{$&}" if test =~ DBL_SYL
>> end
waikiki => kiki
dodo => dodo
paparazzi => papa
=> ["waikiki", "dodo", "paparazzi"]

What about using \1 e.g.

C = "bcdfghjklmnpqrstvwxyz"
V = "aeiou"

%w{ kiki dodo paparazzi abacab }.each do |word|
聽聽聽puts "#{word} matched" if word =~ /([#{C}][#{V}])\1/
end

Hope this helps,

Mike
