Usage

Turn on/off preview popup (commands only defined in quickfix window):

:Quickpeek
:QuickpeekStop
:QuickpeekToggle

It's recommended to create a mapping for QuickpeekToggle, for instance, in ~/.vim/ftplugin/qf.vim, you can do this:

nnoremap <buffer> <c-p> :QuickpeekToggle<cr>

To turn preview popup on automatically, put this in your .vimrc:

let g:quickpeek_auto = v:true

Note that auto mode is currently experimental and results in some weird issues for me sometimes. If you end up with popups hanging around, you can close all of them with :call popup_close().

You can customize the popup that shows up using the g:quickpeek_popup_options variable. See the help docs for more details.

Requirements

The plugin needs Vim with popup window support (v8.1 with a large patch number), otherwise it'll silently do nothing. If you'd like to check if you have popups, try:

:echo exists('*popup_create')

If you get the value of "1", that means you have popup support.
