Cursor position outside buffer, in function 'nvim_win_set_cursor'

[mathjiajia]

I got the error msg as below when using a snippet with callbacks

   Error  20:36:58 msg_show.lua_error E5108: Error executing lua [string ":lua"]:1: Cursor position outside buffer
stack traceback:
	[C]: in function 'nvim_win_set_cursor'
	[string ":lua"]:1: in main chunk

By testing, it is caused by commit 0a4e55701720a111569cadc211b3642b96d7991d.

snippet is given as

s(
	{ trig = "cf" },
	fmta([[\cite[<>]{<>}<>]], { i(1), i(2), i(0) }),
	{
		callbacks = {
			[2] = {
				[events.enter] = function()
					require("telescope").extensions.bibtex.bibtex()
				end,
			},
		},
	}
),

Hi :)

I tried to reproduce this, but couldn't :/
Could you try reducing your setup until the error disappears? One probably source (given the commit) is the new config-option exit_roots, could you try toggling that (or setting that to false if you don't have it currently set)

type cf then <C-k> to expand, fill anything in the 1st insert node, <C-l> jump to the 2nd node, select one entry, then <C-l> to leave.

Here is a minimal config:

-- DO NOT change the paths and don't remove the colorscheme
local root = vim.fn.fnamemodify("./.repro", ":p")

-- set stdpaths to use .repro
for _, name in ipairs({ "config", "data", "state", "cache" }) do
	vim.env[("XDG_%s_HOME"):format(name:upper())] = root .. "/" .. name
end

-- bootstrap lazy
local lazypath = root .. "/plugins/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
	vim.fn.system({
		"git",
		"clone",
		"--filter=blob:none",
		"--single-branch",
		"https://github.com/folke/lazy.nvim.git",
		lazypath,
	})
end
vim.opt.runtimepath:prepend(lazypath)

-- install plugins
local plugins = {
	"folke/tokyonight.nvim",

	-- add any other plugins here
	{
		"nvim-telescope/telescope.nvim",
		dependencies = { "nvim-telescope/telescope-bibtex.nvim" },
		config = function()
			local telescope = require("telescope")
			telescope.setup({ extensions = { bibtex = { format = "plain", context = true } } })
			telescope.load_extension("bibtex")
		end,
	},

	{
		"L3MON4D3/LuaSnip",
		config = function()
			local ls = require("luasnip")

			ls.setup({
				exit_roots = false,
				update_events = "TextChanged,TextChangedI",
				delete_check_events = "TextChanged",
			})

			local s = ls.snippet
			local i = ls.insert_node
			local fmta = require("luasnip.extras.fmt").fmta
			local events = require("luasnip.util.events")

			ls.add_snippets("tex", {
				s({ trig = "cf" }, fmta([[\cite[<>]{<>}<>]], { i(1), i(2), i(0) }), {
					callbacks = {
						[2] = {
							[events.enter] = function()
								require("telescope").extensions.bibtex.bibtex()
							end,
						},
					},
				}),
			}, { key = "tex" })

			vim.keymap.set("i", "<C-k>", function()
				if ls.expandable() then
					ls.expand()
				end
			end, { desc = "LuaSnip Expand" })

			vim.keymap.set({ "i", "s" }, "<C-l>", function()
				if ls.locally_jumpable(1) then
					ls.jump(1)
				end
			end, { desc = "LuaSnip Forward Jump" })
		end,
	},

	{ "nvim-lua/plenary.nvim" },
}

require("lazy").setup(plugins, {
	root = root .. "/plugins",
})

vim.cmd.colorscheme("tokyonight")
-- add anything else here

And you may test with the following files, saving as minimal.tex and minimal.bib:

\documentclass{article}
\usepackage{biblatex}
\addbibresource{minimal.bib}

\begin{document}

\end{document}

@L3MON4D3 could you reproduce this error?

[L3MON4D3]

Hey, I couldn't look into this until now, sorry to keep you waiting.
I think the main issue is that we completely assume that the buffer/window does not change once a call (like jump) begins, and since telescope opens a new window+buffer, this does not hold.

I think we should fix this, and it would actually be desirable, since a fix to this would include some other things I've wanted to tackle for some time, but I don't think I'll have time to do it soon :(
(how: create table that contains parameters to some action (bufnr,winnr, no_move, dry_run) at action-toplevel, pass through to all called functions)

Until then, you can simply vim.schedule(require("telescope").extensions.bibtex.bibtex) to open telescope once luasnip is done with its stuff :)

PS: Thank you for the minimal config, that was a pleasure to work with :D

[mathjiajia]

thanks for the prompt response and the workaround.

[hiberabyss]

will occasionally get this error when used with nvim-cmp.
once error occured, nvim-cmp stop work.
