Panic on `:Oatmeal` -- `EOF while parsing a value at line 1 column 0`

[alexcardell]

Configuration:

require('oatmeal').setup({
  backend = "ollama",
  model = "codellama:latest"
})

Steps to reproduce:

:Oatmeal

Neovim Terminal output (with RUST_BACKTRACE=full):

oatmeal --editor neovim --backend ollama --model codel
lama:latest
Backtrace (most recent call first):
  File "<unknown>", line 0, in oatmeal::main::{{closure}}
  File "<unknown>", line 0, in tokio::runtime::park::CachedParkT
hread::block_on
  File "<unknown>", line 0, in oatmeal::main
  File "<unknown>", line 0, in std::sys_common::backtrace::__rus
t_begin_short_backtrace
  File "<unknown>", line 0, in std::rt::lang_start::{{closure}}
  File "<unknown>", line 0, in std::rt::lang_start_internal
  File "<unknown>", line 0, in _main

The application panicked (crashed).
  called `Result::unwrap()` on an `Err` value: EOF while parsing
 a value at line 1 column 0
in src/main.rs, line 46
thread: main

System: Darwin arm64 Using the standalone binary

oatmeal --backed ollama --model codellama:latest works perfectly fine

I've been digging through the code, but not a Rustacean. Themes loading uses BufReader which would throw this but I'm not setting any theme. Does serde throw this as well?

Thanks for the report! I've just pushed a new version of the CLI to provide clearer panic stack traces so this is easier to debug.

I did mange to repro though, and it's specifically something to do with calling in to Neovim. Could you help me out a do the following, please?

1. Provide the version of Neovim you're using.
2. Execute the following in a neovim terminal and provide me the result (double checking there's no sensitive data first): env | grep NVIM.

Thanks!

Cool project by the way!

Oh no! Oatmeal has failed with the following app version and err

My neovim install is through nix with home-manager, which sometimes does cause permission issues, I was thinking maybe the NVIM socket permissions?

@dustinblackman looks like it was a 0.9.1 neovim issue, noticed I was slightly behind and updated, now it's working fine

[codemeleon]

I tried different versions of neovim and getting following error

$ oatmeal --editor neovim --backend ollama --model codellama:latest
Oh no! Oatmeal has failed with the following app version and error.
Version: 0.2.4

Commit: VERGEN_IDEMPOTENT_OUTPUT
Error: No such file or directory (os error 2)

To report a bug, please rerun your command with the following to print stack traces: 

RUST_BACKTRACE=1 oatmeal --editor neovim --backend ollama --model codellama:latest

It runs fine without editor option.

[dustinblackman]

@codemeleon That one feels odd. Would you mind running the recommended backtrace command please? I'll take a look!

Ah you're not running within a neovim terminal, correct? I should add better error handling there.

[codemeleon]

At first, I tried inside neovim using given command :Oatmeal and got the errors I posted initially

[dustinblackman]

I’ve pushed a few patches since the last comments that I believe solve the issues here. I’ll close for now, and reopen if you’re still experiencing issues. Thanks all for reporting!

[codemeleon]

Apologies. The problem still persists.

[dustinblackman]

The latest version of oatmeal has logging to help debug. Could you run while setting environment variable RUST_LOG=oatmeal please? That should help find the issue :) You can find the log file by running 'oatmeal debug log-path'

The main repo also has docs to use debug builds to help drill down further. https://github.com/dustinblackman/oatmeal#report-an-issue

Note I've set the minimum version of Neovim to 0.9.2 since you've reported the issue. What version are you running?

I'm going to keep this issue closed. Please feel free to open a new one so we can start fresh!
