Capture outer scope variable in config function

[Tastyep]

Hello,

I'm trying to capture a variable into a lambda function, but the variable is always nil.
Am I forced to use a global variable to achieve that, or is there another solution ? Thanks in advance.

Minimal example:

local my_var = 1

use({
"some-plugin",
config = function()
  print("VAR: ", my_var) -- <-- prints nil
end
})

Unfortunately, this is a well-known limitation of string.dump in Lua, which cannot capture closure variables. If you need this kind of capture, you can use a global, or you can pass a string instead of a function to the config key (e.g. [[require(config.some-plugin)]], where ~/.config/nvim/lua/config/some-plugin.lua is a file that does whatever setup you want. Forthcoming changes in #402 will remove this limitation, as we will no longer need to use string.dump.

Alright, thank you for the details 👍
