Read and Write Config on Windows OS

[RichestHumanAlive]

Hey! Awesome plugin there!

I got this error running ChatGPT command on Windows after configuring ChatGPT.nvim according to the README.md :

Error executing Lua callback: ...\pack\packer\start\ChatGPT.nvim/lua/chatgpt/settings.lua:45: attempt to concatenate a nil value
stack traceback:
        ...\pack\packer\start\ChatGPT.nvim/lua/chatgpt/settings.lua:45: in function 'read_config'

The error occurs precisely on this line :

local file = io.open(os.getenv("HOME") .. "/" .. ".chatgpt-" .. M.type .. "-params.json", "rb")

I did some researches and according to StackOverflow HOME is for Linux and on Windows this env variable has different name: USERPROFILE

You can just update the code with this snippet (or optimized version) to fix that issue for Windows users :

local function get_os_name()
  local os = vim.loop.os_uname()
  local os_name = os.sysname
  return os_name
end

local function get_user_profile_key()
  local os_name = get_os_name()

  local user_profile_key = nil
  if os_name == "Windows_NT" or os_name == "Windows" then
    user_profile_key = "USERPROFILE"
  elseif os_name == "Darwin" then
    user_profile_key = "HOME"
  else
    user_profile_key = "HOME"
  end
  return user_profile_key
end

M.read_config = function()
  local file = io.open(os.getenv(get_user_profile_key()) .. "/" .. ".chatgpt-" .. M.type .. "-params.json", "rb")
 -- ... 
end

M.write_config = function(config)
  local file, err = io.open(os.getenv(get_user_profile_key()) .. "/" .. ".chatgpt-" .. M.type .. "-params.json", "w")
-- ...
end

This is what I did and everything works fine now!

Awesome plugin 💯 once again

Thanks for the workaround! For a quickfix I added:

$Env:HOME = $Env:USERPROFILE

to my PowerShell profile.

Neovim has vim.env.HOME, which (as far as I know) returns the HOME folder path independently of the OS you're using.

@jackMort Do you think this can be a PR?
