Special type of string replacement

Ruby
1

Hi,

I want to insert the “​” character in between each character of
a string contained in @user.email. So if the string output were
“[email protected]”, the result would be
“m​e​@​m​i​n​e​.​c​o​m”.

Thanks for the info, - Dave

Something like this will do:
email = “[email protected]”
email[0…-1].gsub(/./){|c| c+“​”}+email[-1…-1]

p “astring”.split("").join(“​”)

I guess you want that to be email[0…-2] not email[0…-1] (otherwise
you’ll
have the last character twice). Anyway, here’s my gsub solution:
email.gsub(/(.)(?=.)/, ‘\1​’)
