A colorscheme for Neovim 0.7+ reimplemented in lua from ayu-vim.

To apply the colorscheme, you can call require('ayu').colorscheme() from lua or use :colorscheme ayu command. By default it respects your 'background' (see :h background) setting to choose between dark and light variants. But you can use the :colorscheme ayu-dark, :colorscheme ayu-light, or :colorscheme ayu-mirage commands to apply a variant directly.

To configure the plugin, you can call require('ayu').setup(values), where values is a dictionary with the parameters you want to override. Here are the defaults:

require('ayu').setup({
    mirage = false, -- Set to `true` to use `mirage` variant instead of `dark` for dark background.
    overrides = {}, -- A dictionary of group names, each associated with a dictionary of parameters (`bg`, `fg`, `sp` and `style`) and colors in hex.
})

Alternatively, overrides can be a function that returns a dictionary of the same format. You can use the function to override based on a dynamic condition, such as the value of 'background'.

Colorscheme also provides a theme for lualine.nvim. You can set in setup lualine:

require('lualine').setup({
  options = {
    theme = 'ayu',
  },
})

1. Replace IncSearch group with foreground set to #FFFFFF:

require('ayu').setup({
  overrides = {
    IncSearch = { fg = '#FFFFFF' }
  }
})

2. Change the background color of non-active windows to make the active one more obvious, specifying overrides for both light and dark backgrounds:

require 'ayu'.setup({
  overrides = function()
    if vim.o.background == 'dark' then
      return { NormalNC = {bg = '#0f151e', fg = '#808080'} }
    else
      return { NormalNC = {bg = '#f0f0f0', fg = '#808080'} }
    end
  end
})

Tip: You can use :source $VIMRUNTIME/syntax/hitest.vim to see all highlighting groups.

3. To get the colors from the colorscheme you can use ayu.colors:

local colors = require('ayu.colors')
colors.generate() -- Pass `true` to enable mirage

require('ayu').setup({
  overrides = {
    IncSearch = { fg = colors.fg }
  }
})

Tip: You can use :lua print(vim.inspect(require('ayu.colors'))) command to check all available colors.
