[tim-hilde]

Make sure you have done the following

• I have updated to the latest version of the plugin.
• I have read the README.

Bug Description

New lines (\n), carriage returns (\r) or * are not recognized. Possibly more

Relevant Screenshot

To Reproduce

Search for/replace with \n, \r or *

Sample Text

this is a test with carraige return and
new lines

neovim version

NVIM v0.10.2

ripgrep version

Minimal reproducible config

local spec = {
	{
		"chrisgrieser/nvim-rip-substitute",
		opts = {}, -- insert config here
		keys = {
      { "gs", function() require("rip-substitute").sub() end, mode = { "n", "x" } },
		},
	},
}
--------------------------------------------------------------------------------
vim.env.LAZY_STDPATH = "./nvim-repro"
load(vim.fn.system("curl -s https://raw.githubusercontent.com/folke/lazy.nvim/main/bootstrap.lua"))()
require("lazy.minit").repro { spec = spec }

Ah, that's technically not a bug, but simply a feature not supported yet.

Search/replace for line breaks entails quite the need for quite a bit of extra logic (file-format specific line breaks, nvim's editor model working with an array of lines, accounting for match at the border of line ranges, etc.)

Also, the incremental preview of replacements affecting \n require the ability to hide complete lines in the buffer, something to my knowledge neovim core does not support yet. Thus, such a feature cannot even be implemented at the moment.

(Btw, search/replace for * should be supported, if you escape it via \*. )
