grep exact word

[Martinits]

Is it possible to grep the exact word under cursor? Or does the current "grep_string" picker support it already?

Do you mean something like this?

local function get_visual_selection()
  vim.cmd('normal! "vy') -- Yank selection into the unnamed register
  return vim.fn.getreg("v")
end

keys = {
  {
    "<leader>fw",
    function()
      require("telescope.builtin").live_grep({
        default_text = vim.fn.expand("<cword>"),
        initial_mode = "normal",
      })
    end,
    desc = "Live Grep current word",
    mode = "n",
  },
  {
    "<leader>fw",
    function()
      require("telescope.builtin").live_grep({
        default_text = get_visual_selection(),
        initial_mode = "normal",
      })
    end,
    desc = "Live Grep selected text",
    mode = "x",
  },
}

Yes, it does already. You can set up a shortcut like this:

vim.keymap.set('n', '<leader>sw', function()
    require('telescope.builtin').grep_string()
end, { desc = '[S]earch current [W]ord' })
-- Or in lazy
{
    'nvim-telescope/telescope.nvim',
    -- ... other settings
    config = function()
        local builtin = require 'telescope.builtin'
        vim.keymap.set('n', '<leader>sw', builtin.grep_string, { desc = '[S]earch current [W]ord' })
    end,
},

I mean to grep the exact word under cursor, like the regex "\bsomeword\b".
I work out with this:

vim.keymap.set('n', '<LEADER>fw',
    function() require('telescope.builtin').grep_string { word_match = '-w' } end,
    { desc = 'telescope: search cursor string' }
)

But it's better to leave the search string on the input box of live_grep so I can modify it. When press the keymap (like fw), the behavior is just like open the live_grep window and type "\bsomeword\b". Does live_grep support any option like this?

Did you try my suggestion up above?
If you prefer you can remove the option initial_mode = "normal" to keep the default insert_mode behavior.

@thi-marques Thanks but your config cannot grep the exact word? Or should I add a pair of \b(I dont know what it should be in vim) around <cword>?
