A pywal based Lush Theme for Neovim.

===

Introduction

This is my first cut at a Lush based theme that utilizes the pywal mechanism for creating a palette based on a background. It builds a lua Table from the ~/.cache/wal/colors and then uses the awesome Lush based primitives to modify the colours dynamically.

Warning

This is also my first lua based anything, your mileage may vary!

Install

VimPlug Plug 'Deep-Six/pywal-lush',{'branch': 'main'}

Configuration

The termguicolors option must be set for this colorscheme.

" set the lightline theme.
let g:lightline = {
    \ 'colorscheme': 'pywal_lush'
    \ }

" set the colorscheme
colorscheme pywal_lush

or in lua:

vim.g.lightline = { colorscheme = "pywal_lush" }

vim.cmd.colorscheme("pywal_lush")

Advanced

Currently, you may use lush to modify the colorscheme directly if you wish. The colors are offered by the theme, so you can also use them directly:

-- you could save this snippet as a `colors.lua` and require() it, or simply
-- include it in an existing file.

local lush = require("lush")
local colors = require("lush_theme.colors")
local theme = require("lush_theme.pywal")

-- lush allows you to modify a theme built using lush before it gets applied.
-- `injected_functions` / `local sym` are only for modifying tree-sitter highlights;
-- feel free to remove them if you're not changing any of those.
local spec = lush.extends({ theme }).with(function (injected_functions)
  local sym = injected_functions.sym

  return {
    -- override the fg for the MatchParen highlight group using a hard-coded value.
    MatchParen { fg = "white" },

    -- modify NormalFloat's bg, by using the theme's NormalFloat original bg color.
    NormalFloat { bg = theme.NormalFloat.bg.darken(80) },

    -- use Comment colors, but don't italicize them (the default).
    Comment { gui = "NONE" },

    -- use theme.Comment.fg for a string, but adjusted (absolute, not relative) lighter.
    String { fg = theme.Comment.fg.abs_lighten(20) },

    -- use pywal-generated colors directly, but darkened/lightened as you wish.
    Search { bg = colors.color8.darken(70), fg = colors.color1.lighten(90) },

    -- change a tree-sitter highlight:
    sym"@string.documentation" { fg = theme.Comment.fg.lighten(20) },
  }
end)

lush(spec)

Todo

Support lualine as well as lightline.
