feature request: improve treesitter node highlighting

[quangd42]

Did you check existing requests?

• I have searched the existing issues

Describe the feature

I'm using the provided snacks picker:

require('aerial').snacks_picker { layout = { preset = 'vscode', preview = 'main' } }

In the preview, the entire treesitter node is reverse highlighted like so

which can be pretty hard to read because the syntax highlighting is lost, and personally the white text on bright blue is pretty bright but that could just be my colorscheme.

I would propose one of the two options

• just highlighting the matched search term like snacks builtin treesitter picker Snacks.picker.treesitter(), which could be an easy fix

- or what Zed does, which could be considered better because the full node is still highlighted but the code is still easy to read

Provide background

As stated above.

What is the significance of this feature?

nice to have

Additional details

I'm not sure if I missed some obvious config, I tried searching through the readme. But even then I would propose to update the default. Thanks!!

I don't see any such highlighting when I use the snacks picker. Perhaps this is an option in snacks? Can you provide a repro config?

[quangd42]

Please find the repro config below. It's not too long so hopefully it's ok that I pasted it here.

-- Bootstrap lazy.nvim
local lazypath = vim.fn.stdpath 'data' .. '/lazy/lazy.nvim'
if not (vim.uv or vim.loop).fs_stat(lazypath) then
  local lazyrepo = 'https://github.com/folke/lazy.nvim.git'
  local out = vim.fn.system { 'git', 'clone', '--filter=blob:none', '--branch=stable', lazyrepo, lazypath }
  if vim.v.shell_error ~= 0 then
    vim.api.nvim_echo({
      { 'Failed to clone lazy.nvim:\n', 'ErrorMsg' },
      { out, 'WarningMsg' },
      { '\nPress any key to exit...' },
    }, true, {})
    vim.fn.getchar()
    os.exit(1)
  end
end
vim.opt.rtp:prepend(lazypath)


vim.cmd.colorscheme 'habamax' -- note colorscheme here


require('lazy').setup {
  spec = {
    -- plugin config here
    {
      'stevearc/aerial.nvim',
      opts = {},
      -- Optional dependencies
      dependencies = {
        'folke/snacks.nvim',
        'nvim-treesitter/nvim-treesitter',
        'nvim-tree/nvim-web-devicons',
      },
      keys = {
        {
          '<leader>ss',
          function()
            require('aerial').snacks_picker { layout = { preset = 'vscode', preview = 'main' } }
          end,
          mode = 'n',
          desc = 'Buffer Symbols (Treesitter)',
        },
      },
    },
  },

  install = { colorscheme = { 'habamax' } },
  checker = { enabled = true },
}

With this config the whole node is still highlighted like so.

Let me know if need more information!
