bug: highlighting does not work correctly

[hnbnh]

Describe the bug

The letter u is highlighted incorrectly

Expected behavior

The letter u in July should be highlighted instead of young

Neovim version

v0.8.2

Configuration (with lazy.nvim)

  {
    "jinh0/eyeliner.nvim",
    event = "VeryLazy",
    config = function()
      require("eyeliner").setup({
        highlight_on_key = true, -- show highlights only after keypress
        dim = true, -- dim all other characters if set to true (recommended!)
      })
    end,
  },

Huh, that's weird, I just tried your configuration and it gave me the correct highlighting.

I'd guess it's one of two things:

• Have you tried setting a specific commit? Maybe the latest one?

  {
  'jinh0/eyeliner.nvim',
  commit = "02f59335bbab955de33f93d2e8c53417a06cfc2f",
  -- the rest of your config
  }

• Maybe it's a matter of the highlight groups? What's your output for the commands :hi EyelinerPrimary and :hi EyelinerSecondary? If they're the same, that might be why they look the same.

You was right, the highlighted colors was the same

EyelinerPrimary xxx cterm= gui= guifg=#ffa066
EyelinerSecondary xxx cterm= gui= guifg=#ffa066

Unfortunately I still have incorrect colors after updating the highlight groups

Here is a minimal init.lua:

local lazypath = vim.fn.stdpath("data") .. "/lazy/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
    vim.fn.system({ "git", "clone", "--filter=blob:none", "https://github.com/folke/lazy.nvim.git", lazypath })
    vim.fn.system({ "git", "-C", lazypath, "checkout", "tags/stable" }) -- last stable release
end
vim.opt.rtp:prepend(lazypath)

local plugins = {
    {
        "rebelot/kanagawa.nvim",
        lazy = false,
        config = function()
            require("kanagawa").setup()
            vim.cmd.colorscheme("kanagawa")
        end,
    },
    {
        "jinh0/eyeliner.nvim",
        event = "VeryLazy",
        commit = "02f59335bbab955de33f93d2e8c53417a06cfc2f",
        config = function()
            vim.api.nvim_set_hl(0, "EyelinerPrimary", { fg = "red", bold = true, underline = true })
            vim.api.nvim_set_hl(0, "EyelinerSecondary", { fg = "orange", underline = true })
            require("eyeliner").setup({
                highlight_on_key = true, -- show highlights only after keypress
                dim = true, -- dim all other characters if set to true (recommended!)
            })
        end,
    },
}

require("lazy").setup(plugins, {
    defaults = { lazy = true, version = nil },
    checker = { enabled = false },
})

That seems to be the right highlighting to me: the u and c are yellow since there's already a u and c in the sentence before it.

Could you explain what is incorrect?

[hnbnh]

I thought it would behave the same as the demo:

Maybe the algorithm has been updated or something?

[jinh0]

Yeah, I updated the algorithm. Technically the demo on the README has a bug since the "n" in "On" shouldn't be highlighted (you're already on the word). The highlight groups are correct in your screenshot.

Thanks for letting me know that the README video is outdated, I'll update it soon!
