Unable to open chat

[sho-87]

I keep running into errors when I try to open the chat window using any of the commands. for example: ChatGPT:

The other ones error in a similar fashion

(this is on windows 11, if relevant)

Did you know how to resolve that yet? 🤔

You're probably running into the problem that Windows does usually not have a HOME environment variable set. There are two pull requests that address this (and some other problems concerning invalid names of session files under Windows), see #45 and #51.

@pitkling when you say "Windows does not usually have a Home env var set" are you referring to Windows Subsystem for Linux or Windows specifically?

Specifically Windows (the OS). Standard Linux systems should have these variables set.

Is there a reason those two PRs weren't accepted yet? 🙏 they have been open for months and seem pretty simple

making this change to the read_config function worked for me

M.read_config = function()
  local home = os.getenv("HOME") or os.getenv("USERPROFILE")
  local filename = home .. "/.chatgpt-" .. M.type .. "-params.json"
  local file = io.open(filename, "rb")
  if not file then
    return nil
  end
  local jsonString = file:read("*a")
  file:close()

  return vim.json.decode(jsonString)
end
