Question

I know my title is not that descriptive/clear so let me explain.

Yesterday I can across Vimgrep and copen so I added the below line in .vimrc

nnoremap <silent> ,/ :execute 'vimgrep /'.@/.'/g %'<CR>:copen<CR>

What it does is open a quickfix list for the searched(highlighted) word in vim.

Now when you press Enter<CR> in quickfix list it takes you to a corresponding line in the main Vim Window.

Now, the problem I am facing is I have mapped my <CR like map <CR> o<Esc> which creates a new line just below the current line.

So, as you can see there is a conflict b/w the two. So, what I am trying is to come up with a vim function like

Pseudo Code

function IfNotInsideQuickFix()
    if buffer != QuickFix
        then map <CR> o<Esc>
    elif buffer == QuickFix
         Normal behaviour

Call function

Here is the output of :buffers

:buffers
  1 #a   "test.cs"                      line 0
  2 %a-  "[Quickfix List]"              line 1
Press ENTER or type command to continue

I have no experience in writing vim functions. So, can someone please guide me to it.

PS: I know that I can change my Vim mapping to create a new line but I want to learn how to do it via Vim function

Answer 1

You can keep your global <CR> mapping as-is, but locally in quickfix windows restore the original behavior. This is done via an :autocmd (triggered when the quickfix window opens) that maps (without remapping) <CR> (locally via <buffer>) onto itself.

:autocmd BufReadPost quickfix nnoremap <buffer> <CR> <CR>
