1. Documentation                                      *zenbones-documentation*

A collection of Vim/Neovim colorschemes designed to highlight code using
contrasts and font variations.


REQUIREMENT                               *zenbones-documentation-requirement*

- Neovim v0.8.0 (use v2.0.0 for older versions) or Vim 8.1


USAGE                                           *zenbones-documentation-usage*

Just apply the colorscheme as usual:

>vim
    set termguicolors
    set background=light " or dark
    
    colorscheme zenbones
    
    " or any from the collection
    colorscheme zenwritten
    colorscheme neobones
    colorscheme vimbones
    colorscheme rosebones
    colorscheme forestbones
    colorscheme nordbones
    colorscheme tokyobones
    colorscheme seoulbones
    colorscheme duckbones
    colorscheme zenburned
    colorscheme kanagawabones
    colorscheme randombones
<


CONFIGURATION                           *zenbones-documentation-configuration*

Configuration is only available for Neovim. There are two ways to set
configuration. First:

>vim
    " vimscript
    let g:zenbones_solid_line_nr = v:true
    let g:zenbones_darken_comments = 45
<

>lua
    -- lua
    vim.g.zenbones_solid_line_nr = true
    vim.g.zenbones_darken_comments = 45
<

Second way is to set configuration is to assign a dictionary to the prefix:

>vim
    " vimscript
    let g:forestbones = #{ solid_line_nr: v:true, darken_comments: 45 }
<

>lua
    -- lua
    vim.g.forestbones = { solid_line_nr = true, darken_comments = 45 }
<

**Notes**: Flavors accept their own configuration by replacing the prefix with
the flavor name e.g. `g:rosebones_italic_comments`.

G:BONES_COMPAT

Set to `1` to enable compatibility mode for all colorschemes. Enabled in Vim.
To enable/disable compatibility mode for a specific theme, set the variable
`g:{theme}_compat` to `0` or `1`, e.g. `let g:zenbones_compat = 1`.


LIGHTLINE ~

>vim
    let g:lightline = #{ colorscheme: 'zenbones' } " or any other flavor
<


LUALINE ~

>lua
    require("lualine").setup {
        options = { theme = "zenbones" }, -- or any other flavor
    }
<


ADVANCED USAGE                         *zenbones-documentation-advanced-usage*

Zenbones is pretty extensible thanks to Lush. You can easily retrieve the
colors in lua:

>lua
    local theme = require "zenbones" -- or any other flavor
    local palette = require "zenbones.palette"
    
    print(theme.StatusLine.bg.hex)
    print(palette.dark.blossom.darken(20).hex)
<


EXTEND/OVERRIDE HIGHLIGHTS ~

Here’s an example of how to extend/override some highlights.

`lua/customize_zenbones.lua`:

>lua
    local lush = require "lush"
    local base = require "zenbones"
    
    -- Create some specs
    local specs = lush.parse(function()
        return {
            TabLine { base.TabLine, gui = "italic" }, -- setting gui to "italic"
        }
    end)
    -- Apply specs using lush tool-chain
    lush.apply(lush.compile(specs))
<

And then somewhere in your `init.vim`:

>vim
    autocmd ColorScheme zenbones lua require "customize_zenbones"
    colorscheme zenbones
<

See also Lush’s documentation
<https://github.com/rktjmp/lush.nvim#advanced-usage> for more options.


CREATE YOUR OWN COLORSCHEME ~

You can ultimately create your own colorscheme that is based on zenbones by
defining a palette and generating a specs. Best way to demonstrate this is
through an example. Let’s make a zenbones-flavored Gruvbox colorscheme called
`gruvbones`.

Let’s define our |colorscheme| in `colors/gruvbones.lua`. It contains the
following:

>lua
    local colors_name = "gruvbones"
    vim.g.colors_name = colors_name -- Required when defining a colorscheme
    
    local lush = require "lush"
    local hsluv = lush.hsluv -- Human-friendly hsl
    local util = require "zenbones.util"
    
    local bg = vim.o.background
    
    -- Define a palette. Use `palette_extend` to fill unspecified colors
    -- Based on https://github.com/gruvbox-community/gruvbox#palette
    local palette
    if bg == "light" then
        palette = util.palette_extend({
            bg = hsluv "#fbf1c7",
            fg = hsluv "#3c3836",
            rose = hsluv "#9d0006",
            leaf = hsluv "#79740e",
            wood = hsluv "#b57614",
            water = hsluv "#076678",
            blossom = hsluv "#8f3f71",
            sky = hsluv "#427b58",
        }, bg)
    else
        palette = util.palette_extend({
            bg = hsluv "#282828",
            fg = hsluv "#ebdbb2",
            rose = hsluv "#fb4934",
            leaf = hsluv "#b8bb26",
            wood = hsluv "#fabd2f",
            water = hsluv "#83a598",
            blossom = hsluv "#d3869b",
            sky = hsluv "#83c07c",
        }, bg)
    end
    
    -- Generate the lush specs using the generator util
    local generator = require "zenbones.specs"
    local base_specs = generator.generate(palette, bg, generator.get_global_config(colors_name, bg))
    
    -- Optionally extend specs using Lush
    local specs = lush.extends({ base_specs }).with(function()
        return {
            Statement { base_specs.Statement, fg = palette.rose },
            Special { fg = palette.water },
            Type { fg = palette.sky, gui = "italic" },
        }
    end)
    
    -- Pass the specs to lush to apply
    lush(specs)
    
    -- Optionally set term colors
    require("zenbones.term").apply_colors(palette)
<

And there you have it. Just call `colorscheme gruvbones` to use your new
colorscheme. It respects `&background` and other configurations too.
