I have a text file where lines are trimmed by newline characters /n and paragraphs by double newlines /n/n

I want to strip out those single newlines and replace with simple spaces. But I do not want the double newlines affected.

I thought something like one of these would work:

(?!\n\n)\n

\n{1}

\n{1,1}

But no luck. Everything I try inevitably ends up affecting those double new lines too. How can I write a regex that effectively "ignores" the /n/n but captures the /n

CodePudding user response：

You can search using this regex:

(.)\n(?!\n)

And replace it with:

"\1 "

Hope this helps. Eager to see other regex answers too! Happy coding
