创建一个 titleize 方法，排除“小词". [英] Create a titleize method, that excludes "little words".

问题描述

我正在制作一种方法来将我的输入大写，除了 a、an 和...等任何单词.

I'm making a method to capitalize my input, except any words such as a, an, and...etc.

def titleize(string_to_titleize)
    string_to_titleize.split(' ').map { |words| words.capitalize }.join(' ')
end

我知道有一些宝石可以做到这一点.我无法掌握如何手动完成.我假设创建一个不大写的单词列表.然后，将他们排除在某人之外.

I understand there are gems to do this. I can't grasp how to do it manually. I assume to create a list of words not to be capitalized. Then, exlude them someone.

推荐答案

arr = ['a', 'an', 'the']
str ="This is a salil gaikwad working as an engineer"
str.gsub(/\w+/) {|match| arr.include?(match) ? match : match.capitalize} 
#Gives o/p :- This Is a Salil Gaikwad Working As an Engineer
