Question

I’m currently studying regex (using ruby) and I would like to find the first occurrence of a non-digit character inside a word and make it capitalized.

I’ve been trying with:

word.gsub!(/\D{0,1}/) do |w|
    w.capitalize
end

hoping it would just catch the first occurrence of a non-digit, but instead it returns all of the letters capitalized.
What’s the correct way to do this?

Many thanks!!!

The g in gsub! stands for “global,” meaning “every occurrence in the string.” You want regular sub! instead. That’ll just find the first. Cheers!
