Question

Is it possible to use :%s to find a match somewhere in a line, and then append it to the line?

With following as an example string, I expected something like :s/\(value\)/\$\1/ to append value to the end of the line, but it just adds $ before value inline

Demo string:

This value is too damn high!

Expected output:

This is too damn high!value

Actual output:

This $value is too damn high!

You could go fast & dirty:

:s,\(.*\)\(value\)\(.*\),\1\3\2,

But there are probably cleaner ways to do it.

For find & append (as stated in question):

:s,\(.*\(value\).*\),\1\2,
