Ruby – 将段落中每个句子的首字母大写
使用Ruby语言，我希望将每个句子的第一个字母大写，并在每个句子结尾处的句号之前删除任何空格。 别的什么都不应该改变。
Input = "this is the First Sentence . this is the Second Sentence ." Output = "This is the First Sentence. This is the Second Sentence." 谢谢大家。
使用正则表达式（ String#gsub ）：
Input = "this is the First Sentence . this is the Second Sentence ." Input.gsub(/[az][^.?!]*/) { |match| match[0].upcase + match[1..-1].rstrip } # => "This is the First Sentence. This is the Second Sentence." Input.gsub(/([az])([^.?!]*)/) { $1.upcase + $2.rstrip } # Using capturing group # => "This is the First Sentence. This is the Second Sentence."
我假设结束了. ， ? ， ! 。
UPDATE
input = "TESTest me is agreat. testme 5 is awesome" input.gsub(/([az])((?:[^.?!]|\.(?=[az]))*)/i) { $1.upcase + $2.rstrip } # => "TESTest me is agreat. Testme 5 is awesome" input = "I'm headed to stackoverflow.com" input.gsub(/([az])((?:[^.?!]|\.(?=[az]))*)/i) { $1.upcase + $2.rstrip } # => "I'm headed to stackoverflow.com"
Input.split('.').map(&:strip).map { |s| s[0].upcase + s[1..-1] + '.' }.join(' ') => "This is the First Sentence. This is the Second Sentence."
我的第二种方法是更清洁但产生略有不同的输出：
Input.split('.').map(&:strip).map(&:capitalize).join('. ') + '.' => "This is the first sentence. This is the second sentence."
我不确定你是不是很好。
