Broken when using Lua5.1

[mirachan010]

Description

Can't move in aarch64(RaspberryPi4-8GB) neovim from apt.
This neovim is use Lua5.1 not LuaJIT.

Expected Behavior

in use :Telescope give some completion.

Actual Behavior

echo some error

:Telescope ...

1. nvim -nu test.vim
2. :Telescope <Tab> OR :Telescope oldfiles

We still have some jit stuff in plenary.path. I will remove them as soon as possible and make sure Lua 5.1 works.
But it will not work as good as the jit version. We need it for some ffi stuff. E.g. we no longer can shorten the path without jit:

telescope.nvim/lua/telescope/path.lua

Lines 23 to 45 in 993e383

	path.shorten = (function()
	if jit then
	local ffi = require('ffi')
	ffi.cdef [[
	typedef unsigned char char_u;
	char_u *shorten_dir(char_u *str);
	]]
	return function(filepath)
	if not filepath then
	return filepath
	end
	local c_str = ffi.new("char[?]", #filepath + 1)
	ffi.copy(c_str, filepath)
	return ffi.string(ffi.C.shorten_dir(c_str))
	end
	else
	return function(filepath)
	return filepath
	end
	end
	end)()

So i highly suggest you build Neovim with luajit.

I will edit the title. Its not really broken for this platform, it works on my raspberry pi 4.

Does this still happen? I have removed the jit part in plenary.path :) I haven't build neovim with lua5.1 yet

It has other error.

I can't install and build lua jit version

After switching to vim-plug from bundle this error stopped popping up. Per the information on this issue this is what fixed it for me

brew install luajit
brew reinstall neovim

@Conni2461 Is this still a thing you are working on? There some architectures out there that doesn't support LuaJIT and therefore use Lua 5.1. Mainly because the LuaJIT maintainer blocks PR's. The neovim team sadly doesn't want to replace luajit with luajit2 upstream.
