将Ctrl-c重新映射到Ctrl-q在输入模式下不起作用

Question

When I try to call ReplaceIt(), I can type ctrl-c to quit input.

function! ReplaceIt()
    call inputsave()
    let replacement = input('Enter replacement:')
    call inputrestore()
    execute '%s//'.replacement.'/g'
endfunction

But I have already map Ctrl-c to <Esc><Esc>, I need to remap other key to Ctrl-c before that.

I try to set map <Cq> <Cc> . This seting is no use while typing.

Is there any better way to remap key or to quit input?

Answer 1

The mode while in input() is command-line mode (ie :cmap ). Even an unmapped <CC> will cause input() to return the empty string, so you should probably check for that ( if empty(replacement) ) and abort your function.

However, I would solve this without explicit input() (which is not efficient and has problems when recalled in a macro):

:nnoremap <Leader>r :%s///g<Left><Left>
