Remove lightline support poll

[ellisonleao]

Following airline removal that happened some time ago, i am also considering removing lightline support as well, focusing this plugin to just support lua based plugins. I am starting a poll to see what you guys think about it. Please vote until the end of September 2023

Seems like a good place to mention crystalline just recently got Lua config support:
https://github.com/rbong/vim-crystalline/blob/master/examples/neovim_lua_examples.md

It includes its own gruvbox light/dark themes.

hm... I was actually still using lightline with gruvbox.nvim, and this broke my config 😅

Is there a way to migrate the lightline themes? I tried to place them in ~/.local/share/nvim/autoload/lightline/colorscheme/gruvbox.nvim, but haven't had success thus far

let s:theme = v:lua.require("gruvbox.groups").setup()

let s:bg0 = s:theme.GruvboxBg0.fg
let s:bg1 = s:theme.GruvboxBg1.fg
let s:bg2 = s:theme.GruvboxBg2.fg
let s:bg4 = s:theme.GruvboxBg4.fg
let s:fg1 = s:theme.GruvboxFg1.fg
let s:fg4 = s:theme.GruvboxFg4.fg

let s:yellow = s:theme.GruvboxYellow.fg
let s:blue = s:theme.GruvboxBlue.fg
let s:aqua = s:theme.GruvboxAqua.fg
let s:orange = s:theme.GruvboxOrange.fg
let s:red = s:theme.GruvboxRed.fg
let s:green = s:theme.GruvboxGreen.fg

let s:palette = {
    \ 'normal': {
    \   'left': [[s:bg0, s:fg4, 'bold'], [s:fg4, s:bg2]],
    \   'middle': [[s:fg4, s:bg1]],
    \   'right': [[s:bg0, s:fg4], [s:fg4, s:bg2]],
    \   'error': [[s:bg0, s:red]],
    \   'warning': [[s:bg0, s:yellow]]
    \ },
    \ 'insert': {
    \   'left': [[s:bg0, s:blue, 'bold'], [s:fg1, s:bg2]],
    \   'middle': [[s:fg4, s:bg1]],
    \   'right': [[s:bg0, s:blue], [s:fg1, s:bg2]]
    \ },
    \ 'inactive': {
    \   'left': [[s:bg4, s:bg1]],
    \   'middle': [[s:bg4, s:bg1]],
    \   'right': [[s:bg4, s:bg1], [s:bg4, s:bg1]]
    \ },
    \ 'terminal': {
    \   'left': [[s:bg0, s:green, 'bold'], [s:fg1, s:bg2]],
    \   'middle': [[s:fg4, s:bg1]],
    \   'right': [[s:bg0, s:green], [s:fg1, s:bg2]]
    \ },
    \ 'replace': {
    \   'left': [[s:bg0, s:aqua, 'bold'], [s:fg1, s:bg2]],
    \   'middle': [[s:fg4, s:bg1]],
    \   'right': [[s:bg0, s:aqua], [s:fg1, s:bg2]]
    \ },
    \ 'visual': {
    \   'left': [[s:bg0, s:orange, 'bold'], [s:bg0, s:bg4]],
    \   'middle': [[s:fg4, s:bg1]],

    \ },
    \ 'tabline': {

    \   'tabsel': [[s:bg0, s:fg4]]
    \ }
  \ }

@perrin4869 any chance you could also move to another statusline plugin, using lua? it's way more reliable IMHO

[perrin4869]

Hm... Don't plan to migrate soon honestly, it works just fine I think...
What kind of problems did you have with it?

[ellisonleao]

@perrin4869 basically the vimscript support which honestly it's already a no-go for me in the neovim ecosystem

[perrin4869]

I see, personally I'm totally fine moving the lightline integration into my repo, no need for gruvbox.nvim to maintain it

I did briefly check lualine and crystalline, but I didn't find that they would improve my setup, so opted to pass on them for now. They aren't much more performant than lightline according to their benchmarks. However, lightline does seem to be somewhat unmaintained so I might migrate in the future

[perrin4869]

In case anyone is interested in the integration to work on the latest HEAD release, you can replace with:

function! ReturnHighlightTerm(group, term)
   " Store output of group to variable
   let output = execute('hi ' . a:group)

   " Find the term we're looking for
   return matchstr(output, a:term.'=\zs\S*')
endfunction

let s:bg0 = ReturnHighlightTerm('GruvboxBg0', 'guifg')
let s:bg1 = ReturnHighlightTerm('GruvboxBg1', 'guifg')
let s:bg2 = ReturnHighlightTerm('GruvboxBg2', 'guifg')
let s:bg4 = ReturnHighlightTerm('GruvboxBg4', 'guifg')
let s:fg1 = ReturnHighlightTerm('GruvboxFg1', 'guifg')
let s:fg4 = ReturnHighlightTerm('GruvboxFg4', 'guifg')

let s:yellow = ReturnHighlightTerm('GruvboxYellow', 'guifg')
let s:blue = ReturnHighlightTerm('GruvboxBlue', 'guifg')
let s:aqua = ReturnHighlightTerm('GruvboxAqua', 'guifg')
let s:orange = ReturnHighlightTerm('GruvboxOrange', 'guifg')
let s:red = ReturnHighlightTerm('GruvboxRed', 'guifg')
let s:green = ReturnHighlightTerm('GruvboxGreen', 'guifg')
