Getting Started

Suggestions

Dependencies

This plugin works with any Neovim theme. The following examples use:

• GruvBox
• Dark Flat

Ensure these plugins are installed for the configurations to work as intended. You can install them using your favorite plugin manager, such as lazy.nvim:

-- Install GruvBox
{
    'morhetz/gruvbox',
    lazy = false
}

-- Install Dark Flat
{
    "sekke276/dark_flat.nvim",
    lazy = false
},

• Having a centralized location for themes - For Example:

-- File: lua/my-themes.lua
local M = {}

-- Example Themes

M.load_gruvbox = function()
   -- Set GruvBox-specific configurations
       vim.opt.termguicolors = true
   vim.g.gruvbox_contrast_light = 'hard'
   vim.cmd([[colorscheme gruvbox]])
   vim.cmd([[
       highlight Normal guibg=NONE ctermbg=NONE
   ]])
end

M.load_dark_flat = function()
   -- Set dark_flat-specific configurations
   vim.cmd.colorscheme "dark_flat"
end

return M

Using The Plugin

    {
        'AryanRogye/theme-picker.nvim',
        config = function()
--          This is where you load in your themes
--          In the suggestions above it shows how to set something similar
--          There is also an example if you decided not to setup a lua file to load themes
            local theme = require("my-themes")
            require("theme-loader").setup({
--              if this is not set no default theme will need keys or command
                default = 1,    -- default index if no keys set
                themes = {
--                  Load Theme in format name = "" func = func <- Make sure no ()
                    { name = "GruvBox", func = theme.load_gruvbox },
                    { name = "Dark Flat", func = theme.load_dark_flat },
--                  This is if You Directly Want To Load Theme Through Here
--                  { name = "GruvBox", func = function()
--                             Set GruvBox-specific configurations
--                             vim.opt.termguicolors = true
--                             vim.g.gruvbox_contrast_light = 'hard'
--                             vim.cmd([[colorscheme gruvbox]])
--                             vim.cmd([[

                },
                -- Default Values Can Change

                    selection = "X"
                    -- Preview on j and k
                    preview = true,
                }
            })
