How to match a key in command line mode, but not in search mode

I want to display the key in VIM in command line mode, but not in search mode (with a leader /), as shown below:

  • Q map on q
  • Map W to w

Sometimes I entered the wrong command in VIM, for example, :Qand :W, and I want these incorrect commands to be correct.

If I can match Qwith Qand Wwith W, I can make the wrong commands correct.

I tried cmap Q qand cmap W w, but it will also affect the search mode, i.e. /Queryon /Query(in fact you cannot enter the top Q).

And I also tried cabbrev Q q, and this will also affect the search mode.

So, is there any other team that can meet my requirements?

Thank.

There are several ways to do this, and it is not so simple.

With commandyou need to take care of the attributes:

command! -nargs=* -complete=file -range=% -bang -bar W w
command! -bang -bar Q q

C cabbrevtraps are described in the wiki , so you need to do this as follows:

cnoreabbrev W <C-r>=(getcmdtype()==':' && getcmdpos()==1 ? 'w' : 'W')<CR>

I have a function for this purpose:

function! s:CAbbrev(from, to)
    execute 'cnoreabbrev ' . a:from . ' <C-r>=(getcmdtype()==#'':'' && getcmdpos()==1 ? ' . string(a:to) . ' : ' . string(a:from) . ')<CR>'
endfunction

cmapYou need a qualifier with you <expr>, and you need more or less the same precautions as for cabbrev:

cnoremap <nowait> <expr> W getcmdtype() ==# ':' && getcmdpos() == 1 ? 'w' : 'W'

The safest way is probably cabbrev.

In this case, you can define a user command because it starts in uppercase.

:command! Q q
:command! W w
