4. Configuration 💎

All settings are:

-- Default options:
require("neofusion").setup({
  terminal_colors = true, -- add neovim terminal colors
  undercurl = true,
  underline = true,
  bold = true,
  italic = {
    strings = true,
    emphasis = true,
    comments = true,
    operators = false,
    folds = true,
  },
  strikethrough = true,
  invert_selection = false,
  invert_signs = false,
  invert_tabline = false,
  invert_intend_guides = false,
  inverse = true, -- invert background for search, diffs, statuslines and errors
  palette_overrides = {},
  overrides = {},
  dim_inactive = false,
  transparent_mode = false,
})

vim.cmd([[ colorscheme neofusion ]])

Important

Make sure to call setup() before the colorscheme command

Lualine

You can apply the built-in lualine theme like so:

require("lualine").setup({
  options = {
    theme = require("neofusion.lualine"),
    -- rest,
  }
})

5. Overriding 👾

a. Palette

You can customize the palette colors like:

require("neofusion").setup({
  palette_overrides = {
    bright_green = "#ec30ac",
    -- rest,
  }
})

vim.cmd([[ colorscheme neofusion ]])

b. Highlight groups

For more flexibility, you can override a specific highlight group:

require("neofusion").setup({
  overrides = {
    SignColumn = { bg = "#ec30ac" },
    -- rest,
  }
})

vim.cmd([[ colorscheme neofusion ]])

It also works with treesitter groups and lsp semantic highlight tokens:

require("neofusion").setup({
  overrides = {
    ["@lsp.type.method"] = { bg = "#ec30ac" },
    ["@comment.lua"] = { bg = "#000000" },
    -- rest,
  }
})

vim.cmd([[ colorscheme neofusion ]])
