FZF integration

[nshern]

Thank you for this project.

Have you considered if it possible to get more utility out of FZF to enable these commands without installing a plugin?

I've searched a lot to find native alternative to fzf. But couldn't find any solution. Neovim don't have builtin fuzzy-find ui. There are some fuzzy find functions (e.g. :h matchfuzzy(),) but both Vim & Neovim don't have builtin fuzzy-find UI. That's why I end up including fzf plugin in this project (it is disabled by default though.)

here's my attempt at adding live_grep functionality like:

local M = {}

M.setup = function()
	vim.opt.runtimepath:append("/opt/homebrew/opt/fzf")
	vim.keymap.set("n", "<leader>fp", "<cmd>FZF<cr>", { noremap = true, silent = true })
	vim.keymap.set('n', '<leader>ff', function() M.live_grep() end,
		{ noremap = true, silent = true })
end

function M.live_grep()
	local command = "rg --column --line-number --no-heading --color=always --smart-case "
	local reload_command = command .. "{q}"

	local preview_command = [[
        if \[ -n {2} \]; then
            bat --style=numbers --color=always --highlight-line {2} {1}
        else
            echo "Start typing to search"
        fi
    ]]

	local opts = {
		options = {
			"--ansi",
			"--prompt", "Rg> ",
			"--delimiter", ":",
			"--preview", preview_command,
			"--bind", "change:reload:" .. reload_command,
			"--preview-window", "+{2}-/2",
			"--phony",
			"--query", ""
		}
	}

	opts["sink*"] = function(lines)
		local parts = vim.split(lines, ":")
		local file = parts[1]
		local line = parts[2]
		local col = parts[3]

		vim.cmd("e " .. vim.fn.fnameescape(file))
		vim.api.nvim_win_set_cursor(0, { tonumber(line), tonumber(col) - 1 })
		vim.cmd('normal! zz')
		return M.handler(lines)
	end

	return vim.fn['fzf#run'](vim.fn['fzf#wrap']({
		options = opts.options,
		sink = opts["sink*"]
	}))
end

return M

this is a mix of me looking at fzf.vim code and asking sonnet for advice, so there might be some issues or better way to do it, but for now it seems ok

I’ll close this issue as NativeVim won’t have that much of custom code.
Reimplementing plugins is not a purpose of this project.
But the code snippet @bpingris commented above is really helpful, so I’ll pin this issue instead.
