Problem

I like to make distance actions using ex commands. It's pretty helpful to remove, copy or move a line or lines to the current position. However, whenever running, some ex command cursor jumps around, and that is so annoying. Every time, after running the ex command, I had to navigate back by pressing Ctrl+o.

Solution

I was looking for a solution on the Internet but didn't find something to solve my problem. So, I came up with the custom function.

function! ExCommandWithoutJump(command)
  try
    execute ":norm! ml"
    execute ":" . a:command
    execute ":norm! `l"
    execute ":delm l"
  catch /.*/
    " Suppress the following errors:
    "   - Line where was mark was removed
    "   - Wrong range entered - No need to echo the error,
    "     as there will be no effect
  endtry
endfunction

nnoremap <leader>ta :call ExCommandWithoutJump('')<Left><Left>

I mapped it to ta.

Testing

Here is the text we're going to operate on.

PHP
Groovy
TypeScript
Shell
PowerShell
Perl
Haskell
Visual Basic .NET
SQL
Delphi
MATLAB
Groovy
Lua
Rust
Ruby
C
Dart
DM
Bash
C#
JavaScript
Java

So if we go all the way down and press ta and then -16d line with Perl will be removed.

Now press gg to go up, ta and +17co.. This will copy and paste the line with Bash without jumping around.
