Rust debug message make nvim think something went wrong

[mraspaud]

I tried using a new build of himalaya with neovim and the rust log debug coming on stderr confuse neovim in that it believes something went wrong.

Eg when sending an email:

A solution is to make an intermediate shell script the quiets down debug messages:
himalaya_fix.sh

#!/bin/sh
RUST_LOG="warn" himalaya

and in nvim/init.lua:

	{
		"pimalaya/himalaya-vim",
		config = function()
			vim.g.himalaya_executable = "~/.local/bin/himalaya_fix.sh"
			vim.g.himalaya_folder_picker = "telescope"
		end,
	},

setting the environment variable inside the init.lua file did not work, neither did setting the variable at nvim call.

One idea coming to my mind is to use stdout for any user output (data and error), and stderr for logs. This way we can easily play with the exit code (which is actually discarded by the Vim plugin — everything captured on stderr is an error):

• If exit code 0, then stdout contains output
• If exit code not 0, then stdout contains an error
• Any data on stderr is a log, and can easily be put in a dedicated buffer.

I fixed the issue on master, so now it should work as expected. For the deeper refactor about stdout, stderr and exit code see pimalaya/himalaya#539.

I still have the same issue after updating to the latest master, eg:

Strange, because it does work for me with CLI on master (15a9a4a) and Vim plugin on master (bb8d0eb). When listing envelopes using the CLI I see warnings, and when listing envelopes via the Vim plugin I don't get any error. Here the Vim config used for testing:

I finally got time to get back to this. I updated himalaya to master, build it with cargo to enable the keyring feature I need, and made sure it’s the one picked by nvim.
Himalaya-vim was already updated to master, so nothing to do there. My config for the plugin in like this (it’s lua as I’m using neovim with the lazy package manager):

  {
    "pimalaya/himalaya-vim",
    config = function()
      vim.g.himalaya_executable = "~/.cargo/bin/himalaya"
      vim.g.himalaya_folder_picker = "telescope"
      vim.g.himalaya_folder_picker_telescope_preview = false
    end,
  },

Listing the envelopes works fine, but as soon as I perform an action, eg deleting an email, the debug comes through and nvim flags it as en error:

I still cannot reproduce. My intuition is that your Lua config bypasses the Vim's one. If you manually add RUST_LOG=off in front of your config, does it work?

vim.g.himalaya_executable = "RUST_LOG=off ~/.cargo/bin/himalaya"

Thanks a lot for your patience! I had tried this before without success, but I tried again right now, and it’s working great! sorry for the noise…
