alphatechnolog/spectrum.nvim

Simple and lightweight VERY WIP theme manager for neovim plugin.

Spectrum.nvim

Spectrum.nvim aims to be a lightweight theme manager for nvim which at this moment is pretty much WIP

Included themes atm

• rustic decay (a new rustic version im working for the decay theme)

Usage

Install fist with lazy.nvim or another package manager of your preference

{
    'AlphaTechnolog/spectrum.nvim',
    lazy = false,
    priority = 100,
    config = function ()
        require("spectrum").setup({
            theme = "decay", -- theme name
            variant = "rustic" -- don't pass if you want the "default" variant
        })
    end
}

Lualine integration

At this moment this plugin has a little lualine integration which can be invoked after calling the setup function.

{
    'nvim-lualine/lualine.nvim',
    config = function ()
        require("lualine").setup({
            options = {
                theme = require("spectrum").get_lualine_theme()
            }
        })
    end
}

Adding more themes

At this moment the only way of adding more themes is by adding a pr in this repo following the next instructions:

1. Create a new folder at lua/spectrum/themes/ with the name of the theme, example is, tokyonight, so the folder is lua/spectrum/themes/tokyonight

2. Create the variants of the theme itself, the default one should be called default.lua, example for tokyonight:

   • lua/spectrum/themes/tokyonight/default.lua
   • lua/spectrum/themes/tokyonight/day.lua
   • lua/spectrum/themes/tokyonight/storm.lua
   • lua/spectrum/themes/tokyonight/moon.lua

3. Take a look at this and fill the colors in the files:

return {
  background = '#110f0f',
  dark_background = '#100e0e',
  light_background = '#1d1a1a',
  lighter_background = '#2a2525',
  black = '#373030',
  light_black = '#413939',
  lighter_black = '#746666',

  red = '#f04a73',
  green = '#87dc76',
  yellow = '#fad874',
  blue = '#7dace9',
  magenta = '#847de9',
  cyan = '#7dd3e9',
  white = '#b5b5cd',

  light_red = '#f26588',
  light_green = '#8ddd7c',
  light_yellow = '#fad97a',
  light_blue = '#83b0ea',
  light_magenta = '#8a83ea',
  light_cyan = '#83d5ea',
  light_white = '#a9a9c5',
}

Those are the rustic decay colors

4. Test your theme!

local lualine = require("lualine")
local spectrum = require("spectrum")

spectrum.setup {
    theme = 'tokyonight',
    variant = 'moon'
}

lualine.setup {
    options = {
        theme = spectrum.get_lualine_theme()
    }
}

5. Submit a PR! :D (leave at least one screenshot for each variant please)

Incoming features

There are some nice features i wanna implement over the time for this plugin.

• Palettes support
• Theming system
• Basic highlighting
• Lualine integration
• Theme switching (functions for next theme and prev themes)
• Better looking themes
• Palettes should also be to change highlights if needed to match original themes

Enjoy
