After neovim 4.0 and vim 8.1, both of them have an amazing feature: popup window.
That's take a look how it makes fzf better.
This is how fzf looks in terminal buffer.
This is how fzf looks in popup window.
There are two reason why I prefer popup window.
- The position of cursor doesn't move.
- Looks more like a "menu".
Configure fzf to use popup window
Thanks to the author of fzf, fzf has supported the popup window.
let g:fzf_layout = { 'window': { 'width': 0.8, 'height': 0.5, 'highlight': 'Comment' } }
When the window entry is a dictionary, fzf will treat the value as the attribute of popup window. Here are some attributes you can set
Required
- width: float range [0 ~ 1]
- height: float range [0 ~ 1]
Optional
- yoffset: float default 0.5 range [0 ~ 1]
- xoffset: float default 0.5 range [0 ~ 1]
- highlight: [string]: Highlight group for border
- border: [string default rounded]: Border style
Avaliable Border Style: rounded: / sharp / horizontal / vertical / top / bottom / left / right
Customize the colors
If you have set colors in FZF_DEFAULT_OPTS, then you don't have to worry this. If not, you can set in shell or neovim.
You can find those elements which can be customized here: https://github.com/junegunn/fzf/blob/a9fba1c8496f7352de55b9fe5f36f23872e5a364/README-VIM.md#L140
shell
export FZF_DEFAULT_OPTS='
--color fg:14,fg+:3,hl:5,hl+:5,bg:-1,bg+:-1
--color info:6,prompt:6,spinner:1,pointer:3
'
Well, yes, pass two '--color' to fzf is legal.
neovim
It's a little harder than in shell. You need to set g:fzf_colors
let g:fzf_colors =
\ { 'fg+': ['fg', 'CursorLine', 'CursorColumn', 'Normal'],
\ 'bg+': ['bg', 'CursorLine', 'CursorColumn'] }
Uh...what are them ?
For example
'bg+': ['bg', 'CursorLine', 'CursorColumn']
The logic is
- FZF will color 'bg+' with the 'bg' of highlight group 'CursorLine'.
- If 'CursorLine' doesn't have 'bg', then find in 'CursorColumn' and so on.
- If none of them have 'bg', use default value.
If you don't like to use an unrelated highlight group like me, you can create new ones for fzf.
hi! fzf_fg ctermfg=14
hi! fzf_fgp ctermfg=3
hi! fzf_hl ctermfg=5
hi! fzf_hlp ctermfg=5
hi! fzf_info ctermfg=6
hi! fzf_prompt ctermfg=6
hi! fzf_spinner ctermfg=6
hi! fzf_pointer ctermfg=3
let g:fzf_colors = {
\ 'fg': ['fg', 'fzf_fg'],
\ 'hl': ['fg', 'fzf_hl'],
\ 'fg+': ['fg', 'fzf_fgp'],
\ 'hl+': ['fg', 'fzf_hlp'],
\ 'info': ['fg', 'fzf_info'],
\ 'prompt': ['fg', 'fzf_prompt'],
\ 'pointer': ['fg', 'fzf_pointer'],
\ 'spinner': ['fg', 'fzf_spinner'] }
By the way, you can also do this to the highlight attribute of g:fzf_layout.
FZF will generate the color setting from g:fzf_colors. To check the generated result, use this vim command
:echo fzf#wrap()
If enerything is good, fzf will trans g:fzf_colors to the format of FZF_DEFAULT_OPTS
{'options': '''--color=info:6,spinner:6,hl:5,fg:14,fg+:3,pointer:3,prompt:6,hl+:5'' --expect=ctrl-v,ctrl-x,ctrl-t', 'sink*': func
tion('283'), 'window': {'highlight': 'fzf_popup', 'width': 0.8, 'height': 0.5}, '_action': {'ctrl-v': 'vsplit', 'ctrl-x': 'split',
'ctrl-t': 'tab split'}}

Well, how do I know the color number ?
If you use 256 color, you can reference this cheat sheet: https://jonasjacek.github.io/colors/
Or this tiny script
for i in {0..255}; do
printf "\x1b[38;5;${i}m%-9s\x1b[0m" "colour${i}"
if (( $i % 5 == 0 )); then
printf "\n"
else
printf " "
fi
done

While setting up yet another MacBook Pro, I saw this floating window and I thought it was something wrong with my config files, wanted to go back to the terminal buffer mode. When I finally found this post, I agreed that it's cooler to have popup windows since the cursor doesn't move.. So I'll use it.
Thanks for keeping people up-to-date and not afraid of new things!
