How to get the raw expand snippet text?

[xzbdmw]

Say I choose local in nvim cmp, after expansion, it will insert

local function()

end

how do I get the raw text so that I can make ghost text display function() instead of function$1($2), I want to change their implementation to expand early

I manually concat static_text in

LuaSnip/lua/luasnip/nodes/node.lua

Line 65 in a7a4b46

function Node:put_initial(pos)

using this function

local function put(lines, text, pos)
	local lineIndex = pos[1]
	local colIndex = pos[2] + 1
	for i, txt in ipairs(text) do
		if lines[lineIndex] then
			lines[lineIndex] = lines[lineIndex] .. txt
		else
			lines[lineIndex] = txt
		end

		if i < #text then
			lineIndex = lineIndex + 1
			colIndex = 1
		else
			colIndex = colIndex + #txt
		end
	end
end

can achieve hrsh7th/nvim-cmp#1862 (comment)
It there any similar api I can use or can you add something similar to api?

Hey, you can try snip:get_static_text(), that should work if you call it on a snippet obtained from ls.get_snippets

Very cool idea btw 👍

Hi, get_static_text don't have indentation information about current cursor position,

get_ghost_text text: { "r index, value in ipairs(t) do", "\t", "end" }
get_ghost_text res: {
  [451] = "r index, value in ipairs(t) do",
  [452] = "\t\t",
  [453] = "\tend"
}

When I type for after a tab, text is get_static_text's return value and res the return value of put function I comment above which manually concat spaces.

Ahhh, right.. I think you might be able to fix this by calling get_static_text on snip:copy():indent("<indentation at cursor>") instead of snip (copy so the indentation does not end up in the stored snippet)

Thanks, that work nice!
