How to change the highlight style using vim-illuminate?

Problem

vim-illuminate is a (Neo)Vim plugin for automatically highlighting other uses of the word under the cursor using either LSP, Tree-sitter, or regex matching.

However, I don’t like the default highlight style of the current version.

In this tutorial, I will guide you how to change it.

Solution

The minimal config should look like below:

require("illuminate").configure{}

-- change the highlight style
vim.api.nvim_set_hl(0, "IlluminatedWordText", { link = "Visual" })
vim.api.nvim_set_hl(0, "IlluminatedWordRead", { link = "Visual" })
vim.api.nvim_set_hl(0, "IlluminatedWordWrite", { link = "Visual" })

--- auto update the highlight style on colorscheme change
vim.api.nvim_create_autocmd({ "ColorScheme" }, {
  pattern = { "*" },
  callback = function(ev)
    vim.api.nvim_set_hl(0, "IlluminatedWordText", { link = "Visual" })
    vim.api.nvim_set_hl(0, "IlluminatedWordRead", { link = "Visual" })
    vim.api.nvim_set_hl(0, "IlluminatedWordWrite", { link = "Visual" })
  end
})
require("illuminate").configure{}

-- change the highlight style
vim.api.nvim_set_hl(0, "IlluminatedWordText", { link = "Visual" })
vim.api.nvim_set_hl(0, "IlluminatedWordRead", { link = "Visual" })
vim.api.nvim_set_hl(0, "IlluminatedWordWrite", { link = "Visual" })

--- auto update the highlight style on colorscheme change
vim.api.nvim_create_autocmd({ "ColorScheme" }, {
  pattern = { "*" },
  callback = function(ev)
    vim.api.nvim_set_hl(0, "IlluminatedWordText", { link = "Visual" })
    vim.api.nvim_set_hl(0, "IlluminatedWordRead", { link = "Visual" })
    vim.api.nvim_set_hl(0, "IlluminatedWordWrite", { link = "Visual" })
  end
})

You can customize the above snippet code to fit your need.

Hope this help!
