How to disable a built-in command in vim

问题:

In vim, when I hit :wq it is almost always an accident that occurred when attempting to input :w. I would like to disable :wq.

The closest I found is cmap, but it has some odd behavior. If I do something like

:cmap wq w

I can no longer even input :wq; it just remaps the keystroke sequence wq to w in command mode. Now I cannot, for example, input a search/replace command on a string containing wq.

I would just like to alias the exact command :wq to :w or a no-op. Is there a way to do this?

EDIT: clarified why :cmap is not an option for me

回答1:

A better solution can be:

:cabbrev wq w

But I'm not sure why cmap doesn't work as excepted. Actually I had mapped one my function keys to save files:

:map <F2> :w<CR>
:nmap <F2> <ESC>:w<CR>i

UPDATE: typo corrected in the first command.

UPDATE2: possible workaround:

:cabbrev wq<CR> w

HTH

It looks like the best option is to just get used to :cmap behavior. In the rare event I want to input the keyboard seqeunce wq I can just hit wq, wait a second, then hit q again. I did find this possible solution but it is too complex for my tastes.

I added a one-line patch and ran dpkg-rebuildpackage for renaming :wa to :wwa:

You will need to create this patch in debian/patches/ and add it to debian/patches/series.
