Multi-line export formatting and adjustments

Development Export
1

I need help with the function exporting multi-line content (e.g. lyrics) to a text file. As a test content I used:

Vestibulum tincidunt varius tortor, laoreet elementum lorem iaculis eget.

Aenean eleifend tortor vitae dolor blandit laoreet.

Etiam vel pellentesque enim.

Aenean eleifend.

I tried $regexp(%lyrics%,'(.{1,55})(\s|$)','** $1 **\n')
But the output was:

**    Vestibulum tincidunt varius tortor, laoreet elementum    **
**    lorem iaculis eget.

Aenean eleifend tortor vitae    **
**    dolor blandit laoreet.

Etiam vel pellentesque enim.    **
**
Aenean eleifend.    **

It looks like a problem with handling empty lines.

have you tried ||\r\n')?

Apparently, the MP3tag regular expression engine does not support "do not return after match".
You would have to find something else.
