Gruvbox Material Scheme

[!NOTE] This is a continuation of the original work from WittyJudge: https://github.com/WIttyJudge/gruvbox-material.nvim

A port of gruvbox-material colorscheme for Neovim written in Lua. It does not aim to be 100% compatible with the mentioned repository, but rather focuses on keeping the existing scheme stable and to support popular plugins. This colorscheme supports both dark and light themes, based on configured background, and harder or softer contrasts.

Dark theme:

Light theme:

Installation

[!NOTE] This plugin requires Neovim >= 0.5.0

Install via your favourite package manager:

vim-plug

Plug 'f4z3r/gruvbox-material.nvim'

packer

use 'f4z3r/gruvbox-material.nvim'

lazy

{
  'f4z3r/gruvbox-material.nvim',
  name = 'gruvbox-material',
  lazy = false,
  priority = 1000,
  opts = {},
},

Usage and Configuration

Load the color scheme and define the desired options:

-- values shown are defaults and will be used if not provided
require('gruvbox-material').setup({
  italics = true,             -- enable italics in general
  contrast = "medium",        -- set contrast, can be any of "hard", "medium", "soft"
  comments = {
    italics = true,           -- enable italic comments
  },
  background = {
    transparent = false,      -- set the background to transparent
  },
  float = {
    force_background = false, -- force background on floats even when background.transparent is set
    background_color = nil,   -- set color for float backgrounds. If nil, uses the default color set
                              -- by the color scheme
  },
  signs = {
    highlight = true,         -- whether to highlight signs
  },
  customize = nil,            -- customize the theme in any way you desire, see below what this
                              -- configuration accepts
})

Customization

In the configuration, you can set customize to a function to modify the theme on the fly. This value accepts a function that takes a highlight group name and some options, and returns some options.

The function signature is:

fun(group: string, options: table): table

Where both the options table and the return table are options as described in the [nvim_set_hl](https://neovim.io/doc/user/api.html#nvim_set_hl()) val parameter.

For instance, in order to disable bold usage on the entire color scheme, you can use

require('gruvbox-material').setup({
  customize = function(_, o)
    o.bold = false
    return o
  end,
})

Or if you want to change the coloring from a specific highlight group, in this case set the current line number to a bold orange instead of the default grey:

-- get colors from the colorscheme for current background and "medium" contrast
local colors = require("gruvbox-material.colors").get(vim.o.background, "medium")

require('gruvbox-material').setup({
  customize = function(g, o)
    if g == "CursorLineNr" then
      o.link = nil            -- wipe a potential link, which would take precedence over other
                              -- attributes
      o.fg = colors.orange    -- or use any color in "#rrggbb" hex format
      o.bold = true
    end
    return o
  end,
})
