VIM , how to show the count of occurrence the current match pattern under cursor? -

how show count of occurrence current match pattern under cursor ? example:

aa bb aab   searching aa, cursor here, show 2.  aa bb 

and how insert number 2 after line . "aab" -> "aab 2"

here function , mapping job (add these lines end of .vimrc; needs @ least vim 7.4 , nocompatible set before it):

nnoremap  x  :call count( '<c-r>=expand( '<cword>' )<cr>' )<cr>  function! count( word )   redir => cnt     silent exe '%s/' . a:word . '//n'   redir end   silent exe 's/.*/& ' . matchstr( cnt, '\d\+' ) . '/' endfunction 

if pressing x on word (bordered withespace characters), count function add count of same words in file end of actual line.

to add ordinal number, change count nthcount in mapping , add these lines .vimrc:

function! nthcount( word )   redir => nth     silent exe '0,.s/' . a:word . '//n'   redir => cnt     silent exe '%s/' . a:word . '//n'   redir end   silent exe 's/.*/& ' . matchstr( nth, '\d\+' ) . '/'   echo a:word . ': ' . matchstr( nth, '\d\+' ) . '/' . matchstr( cnt, '\d\+' ) endfunction 

for example pressing on first bb:

aa bb 1 aab aa bb -- statusline -- bb: 1/2
