Newline markers in the regular expressions or how to match N repeated instances of lines matching the same regex?

[ErtHub]

Hello 🙂

Header comments in my project files always contain a few words of description of what the file is and what it does. Now, depending on whether it is a huge file or not, the description may be single- or multiline. I have tried to construct a config that would match my comment in both cases, so I came up with a regex containing a newline and a multiplier symbol, such as: .+(\n.+)*. Unfortunately, the header plugin does not match any comments if the regex contains \n.

How can I make the plugin match newlines or otherwise prepare a proper config for a case when the number of lines of description is not known beforehand?

Kind regards,
Hubert
