下午好。我想在行首添加连字符（破折号），而行首没有连字符破折号。例如，我有以下文本：
I love books.
I want some money.
I need help.
- I want to ask you something.
- I want to love you.
I need hits.
- I get done with this.
输出应该是：
- I love books.
- I want some money.
- I need help.
- I want to ask you something.
- I want to love you.
- I need hits.
- I get done with this.
答案1
在行首没有连字符的地方添加连字符。
寻找：^(?!-)
替换为：-\x20
或者
寻找：^(?!-)(?:\r?|\r)
替换为：-\x20
如果您只想在空白行处添加连字符（破折号）：
寻找：^(?!-)\s*\r
替换为：-\x20
或者
寻找：^(?!-)(?!\w+)
替换为：-\x20
