vim-monokai-basilisk

A monokai theme for Vim and Neovim, based on Monokai-phoenix.

Features

• Native Lua colorscheme for Neovim (0.9+) with VimScript fallback for Vim
• Treesitter highlight groups
• LSP semantic token highlights
• Diagnostics with undercurl support
• Language-specific highlights for Elixir, Markdown, and YAML
• Plugin integrations: telescope, nvim-cmp, gitsigns, indent-blankline, coc.nvim, render-markdown
• Configurable transparency, italic styles, and per-plugin toggles
• on_colors and on_highlights hooks for full customization

Requirements

• Neovim >= 0.9 (for Lua colorscheme support)
• termguicolors enabled (set automatically by the theme)
• Vim 8+ also supported via the legacy VimScript colorscheme

require("monokai-basilisk").setup({
  -- Enable transparent background
  transparent = false,

  -- Font style overrides
  styles = {
    comments = { italic = true },
    keywords = { italic = false },
    functions = { italic = false },
    strings = { italic = false },
  },

  -- Toggle plugin integrations (all enabled by default)
  plugins = {

    telescope = true,
    cmp = true,
    gitsigns = true,
    indent_blankline = true,
    render_markdown = true,
  },

  -- Override palette colors
  on_colors = function(colors)
    -- colors.green = { gui = "#A6E22E", cterm = 118 }
  end,

  -- Override highlight groups
  on_highlights = function(highlights, colors)
    -- highlights.Normal = { fg = colors.fg.gui, bg = "#1a1a1a" }
  end,
})

vim.cmd.colorscheme("monokai-basilisk")

Plugin Support

The theme includes highlight groups for:

• telescope.nvim
• nvim-cmp
• gitsigns.nvim
• indent-blankline.nvim
• coc.nvim
• render-markdown.nvim

Issues

• nvim-qt#145 does not apply terminal cursor color correctly. This is specific to this application and I can therefore not apply a fix directly. There is however a fix for it: hi TermCursor cterm=reverse gui=reverse should display the cursor correctly.
