段落首字母大写句子，如何改写成长尾？

本文共计320个文字，预计阅读时间需要2分钟。

使用Ruby语言，我想将每个句子的第一个字母大写，并在每个句子的结尾处删除任何空格。以下是一个简单的实现：

rubyinput=this is the First Sentence. this is the Second Sentence.output=input.split('.').map { |sentence| sentence.strip.capitalize }.join('. ')puts output

输出结果：This is the First Sentence. This is the Second Sentence.

使用 Ruby语言,我想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(/[a-z][^.?!]*/) { |match| match[0].upcase + match[1..-1].rstrip } # => "This is the First Sentence. This is the Second Sentence." Input.gsub(/([a-z])([^.?!]*)/) { $1.upcase + $2.rstrip } # Using capturing group # => "This is the First Sentence. This is the Second Sentence."

我认为句子以.,？,！结尾.

UPDATE

input = "TESTest me is agreat. testme 5 is awesome" input.gsub(/([a-z])((?:[^.?!]|\.(?=[a-z]))*)/i) { $1.upcase + $2.rstrip } # => "TESTest me is agreat. Testme 5 is awesome" input = "I'm headed to stackoverflow.com" input.gsub(/([a-z])((?:[^.?!]|\.(?=[a-z]))*)/i) { $1.upcase + $2.rstrip } # => "I'm headed to stackoverflow.com"
