Overriding Lualine Highlights

[iton0]

I want to override the Lualine A section to use the highlight fg and bg of Lualine C. Am I getting the highlight group correctly in the code below

  on_highlights = function(highlight_groups, palette)
        highlight_groups.lualine_a_normal =
          { bg = palette.bg1, fg = palette.grey1 }
  end,

Hi there! Lualine is a bit of an edge case in this regard since it doesn't use the standard highlights. It uses everforest.lua as its highlights. There isn't anything in the plugin currently to handle this. I think the best way is to override it in your lualine config:

local everforest = require("everforest")
local colours = require("everforest.colours")
local everforest_lualine = require("lualine.themes.everforest") -- This may clash?

-- Instead of `everforest.config`, you can add in your own config here by using
-- `everforest.setup({ show_eob = false)` before you generate the palette.
local palette = colours.generate_palette(everforest.config, vim.o.background)

everforest_lualine.normal.a = { bg = palette.bg1, fg = palette.grey1 }

local lualine = require("lualine")
lualine.setup({
  options = { theme = everforest_lualine }
})

This works beautifully. Thank you!
