}

🚀 Usage

Vim Script

colorscheme solarized-osaka

Lua

vim.cmd[[colorscheme solarized-osaka]]

⚙️ Configuration

❗️ Set the configuration BEFORE loading the color scheme with colorscheme solarized-osaka.

The theme offers four styles: storm, moon, night, and day.

The day style is used when { style = "day" } is passed to setup(options) or when vim.o.background = "light".

Solarized Osaka uses the default options, unless setup is explicitly called.

require("solarized-osaka").setup({
  -- your configuration comes here
  -- or leave it empty to use the default settings
  transparent = false, -- Enable this to disable setting the background color
  terminal_colors = true, -- Configure the colors used when opening a `:terminal` in [Neovim](https://github.com/neovim/neovim)
  styles = {
    -- Style to be applied to different syntax groups
    -- Value is any valid attr-list value for `:help nvim_set_hl`
    comments = { italic = true },
    keywords = { italic = true },
    functions = {},
    variables = {},
    -- Background styles. Can be "dark", "transparent" or "normal"
    sidebars = "dark", -- style for sidebars, see below
    floats = "dark", -- style for floating windows
  },
  sidebars = { "qf", "help" }, -- Set a darker background on sidebar-like windows. For example: `["qf", "vista_kind", "terminal", "packer"]`
  day_brightness = 0.3, -- Adjusts the brightness of the colors of the **Day** style. Number between 0 and 1, from dull to vibrant colors
  hide_inactive_statusline = false, -- Enabling this option, will hide inactive statuslines and replace them with a thin border instead. Should work with the standard **StatusLine** and **LuaLine**.
  dim_inactive = false, -- dims inactive windows
  lualine_bold = false, -- When `true`, section headers in the lualine theme will be bold

  --- You can override specific color groups to use other groups or a hex color
  --- function will be called with a ColorScheme table
  ---@param colors ColorScheme
  on_colors = function(colors) end,

  --- You can override specific highlights to use other groups or a hex color
  --- function will be called with a Highlights and ColorScheme table
  ---@param highlights Highlights
  ---@param colors ColorScheme
  on_highlights = function(highlights, colors) end,
})

🪓 Overriding Colors & Highlight Groups

How the highlight groups are calculated:

1. colors are determined based on your configuration, with the ability to override them using config.on_colors(colors).
2. These colors are utilized to generate the highlight groups.
3. config.on_highlights(highlights, colors) can be used to override highlight groups.

For default values of colors and highlights, please consult the colors.lua file.

Settings and color alteration demonstration

require("solarized-osaka").setup({
  -- disable italic for functions
  styles = {
    functions = {}
  },
  sidebars = { "qf", "vista_kind", "terminal", "packer" },
  -- Change the "hint" color to the "orange" color, and make the "error" color bright red
  on_colors = function(colors)
    colors.hint = colors.orange
    colors.error = "#ff0000"
  end
})

Borderless Telescope example

require("solarized-osaka").setup({
  on_highlights = function(hl, c)
    local prompt = "#2d3149"
    hl.TelescopeNormal = {
      bg = c.bg_dark,
      fg = c.fg_dark,
    }
    hl.TelescopeBorder = {
      bg = c.bg_dark,
      fg = c.bg_dark,
    }
    hl.TelescopePromptNormal = {
      bg = prompt,
    }
    hl.TelescopePromptBorder = {
      bg = prompt,
      fg = prompt,
    }
    hl.TelescopePromptTitle = {
      bg = prompt,
      fg = prompt,
    }
    hl.TelescopePreviewTitle = {
      bg = c.bg_dark,
      fg = c.bg_dark,
    }
    hl.TelescopeResultsTitle = {
      bg = c.bg_dark,
      fg = c.bg_dark,
    }
  end,
})

Fix undercurls in Tmux

To have undercurls show up and in color, add the following to your Tmux configuration file:

# Undercurl
set -g default-terminal "${TERM}"
set -as terminal-overrides ',*:Smulx=\E[4::%p1%dm'  # undercurl support
set -as terminal-overrides ',*:Setulc=\E[58::2::%p1%{65536}%/%d::%p1%{256}%/%{255}%&%d::%p1%{255}%&%d%;m'  # underscore colours - needs tmux-3.0
