How to clear the line number in Vim when copying?

Question

I copy some code from one part of one file to another part in vim, I find that, there are line numbers in each line and the format is gone, how to set correct format as origin ?

like this:

            40         root /opt/release/current/public;  67             41         passenger_enabled on;  68              42  

Answer 1

If you have line numbers, I'm quite sure you are not using Vim's yank/put operations (these will never copy the linenumbers, foldcolumn, icons etc) because in terms of the edit buffer, they don't exist.

My guess is you are working in a terminal emulator and using the mouse to copy stuff to the clipboard, which possibly selects the 'extraneous' room of the screen (including virtual spaces at the end, line numbers, fold markers etc)

You might have luck setting

:se mouse+=a 

in order to get the behaviour of the mouse like you expect it. Otherwise, do the selection with V<movement>...y (y for yank, which corresponds to 'copy')

Then on the destination use p (put at cursor), or P (put before cursor)

Let me know if that helped or you need more info

Answer 2

In normal mode, type :se nonu

This is the easiest way to remove the line numbers and you will be able to copy the text without the line numbers.
