Letter Counter

Question

I want to count only letters in text, how should I exclude symbols like dots?
lcount - number of letters
text.each_char { |char| lcount += 1 if idontknowwhattodo}

Answer 1

If current char is equal to dot then continue else increment letter count

Answer 2

you can use regexp to strip all punctuation and special characters, leaving only alphanumeric characters and spaces, so that it's easy to count.
i give you an example.

class String
def to_alphanumeric
gsub(/[^\w\s]/, '')
end
end

count = test.to_alphanumeric.split(/ /).size

maybe you shoud test it first
