Add 'sd' replace method

I guess you need to modify the following:

nvim-spectre/lua/spectre/config.lua

Lines 220 to 225 in 31f62d7

	if vim.loop.os_uname().sysname == 'Darwin' then
	config.replace_engine.sed.cmd = 'gsed'
	if vim.fn.executable('gsed') == 0 then
	print("You need to install gnu sed 'brew install gnu-sed'")
	end
	end

This will change the defaults. My PR is to add 'sd' support, not override the default. Additionally, your line is about changing the replace_engine of sed. The replace engine of sd is always sd, as its installed by the user which means it will always be the same no matter the uname.

To enable sd (in your personal lua config):

require("spectre").setup {
    default = {
        replace = {
            cmd = "sd"
        }
    }
}

Let me know if I misunderstood your comment and that indeed I should add/change anything.

No. Even if I set sd as default,
these piece of code still will run on macOS

nvim-spectre/lua/spectre/config.lua

Lines 220 to 225 in 31f62d7

	if vim.loop.os_uname().sysname == 'Darwin' then
	config.replace_engine.sed.cmd = 'gsed'
	if vim.fn.executable('gsed') == 0 then
	print("You need to install gnu sed 'brew install gnu-sed'")
	end
	end

In the case I removed gnu-sed, it will print that notification.

It should execute only in the case that user sets default replacement tool as sed.

Aha, I understand what you mean now.

However, this code would also run if one set the replace cmd to 'oxi', which is another alternative. I would report it as a bug and not that the current PR is missing.

Though, since I am already in the headspace, I can make another PR fixing the issue 👍.
