如何检测字符串中的笑词? [英] How can I detect laughing words in a string?

问题描述

我试图在字符串中检测诸如hahahaha"和lolololol"之类的笑词.

I'm trying to detect laughing words like "hahahaha" and "lolololol" in a string.

目前我正在使用以下正则表达式:

Currently I'm using the following regex:

^((.*?)|)(\b[ha]|\b[lo])(.*?)$

但是，这不符合我的目的.它有效，但它也匹配与笑声完全无关的词，例如kill"，因为它只查找包含字母 l、o、h、a 的任何词.

However, this doesn't work for my purposes. It works, but it also matches words totally unrelated to laughter, such as 'kill', because it simply looks for any word that contains the letters l, o, h, a.

如何检测字符串中的笑词(如hahaha"或lololol")?

推荐答案

试试这个模式:

\b(?:a*(?:ha)+h?|(?:l+o+)+l+)\b

或者更好，如果您的正则表达式支持原子组和所有格量词:

or better if your regex flavour support atomic groups and possessive quantifiers:

\b(?>a*+(?:ha)++h?|(?:l+o+)++l+)\b
