using a regex. What regex to use? How to put all this rows together?

Answer 1

You may use a regex like

^(?:---+Rs*)*(w.*)R---+R(?:h*R)*(w.*)R---+$

And replace with $1:$2.

The ^ matches the line start, (?:---+Rs*)* matches optional delimiter lines before the first non-empty line, (w.*) is Group 1 capturing a word char followed with 0+ chars other than a newline, R---+R matches a line break followed with 3+ hyphens and a linebreak, (?:h*R)* matches n number of blank lines, (w.*) (see above) and R---+$ matches a linebreak and 3+ hyphens at the end of the line.
