Hi AK,
I came up with a solution. I wrote a function that takes a Vim command and: (1)
put the current position into the jump list; and (2) execute the command,
passing a count (if given) and its argument if it takes one:
function! MarkAndExecute(cmd, has_char_arg)
let c = (a:has_char_arg != 0) ? nr2char(getchar()) : ''
let n = (v:count != 0) ? v:count : ''
" Put the current position into the jump list
normal m'
" Execute the wrapped command
silent exec 'normal! '.n.a:cmd.c
endfunction
Then, I remap the usual character-wise commands (such as $, 0, w, gm, f, ;,
etc.) to appropriately call the above mentioned function. For instance:
nnoremap <silent> $ :<C-U>call MarkAndExecute("$", 0)<CR>
nnoremap <silent> w :<C-U>call MarkAndExecute("w", 0)<CR>
nnoremap <silent> f :<C-U>call MarkAndExecute("f", 1)<CR>
...
Thus, pressing CTRL-O after a jump on the line puts the cursor back to the
original position. It also works with aggregated commands, such as '3w', 'y$',
or even 'y2fc'. :)
Current issue: I couldn't figure out how to properly map commands/keys like
<Home> or g<End>. For example, I've tried to pass <Home> to MarkAndExecute as
"<Home>", '<Home>', '\<Home>', '<lt>Home>', and '\<lt>Home>' without success.
I will work to test/improve the current plugin and then publish it; I think it
can also be useful for somebody else. Last but not least, I'm new to Vim
scripting, so I really appreciate suggestions.
