如何告诉 vim 忽略命令类型错误并且不要进入插入模式

Question

I use vim with Youcompleteme .

I set some key maps in.vimrc, for example:

let mapleader=','
nmap <leader>imp :YcmCompleter GoToImplementation<CR>

My whole.vimrc is here , it's a bit of messy.

sometimes I mistype ",imp" to ",im", or other mistypes. And vim behaves strange. I uploaded an ascii recording here .

My question is how to tell vim to ignore commands if not matched against any key maps I set in.vimrc?

Answer 1

You can map any common undesired lead-ins to do nothing:

nnoremap ,imp :YcmCompleter GoToImplementation<CR>
nnoremap ,im <esc>

You can obviously not map any mistypo to be ignored. You would for instance still like imp to insert mp
