Unable to use the diff view

[shandilya1998]

Hey! Great plugin you have implemented. I am trying to setup the plugin for use with neovim inside a docker container. I am using neovim version 0.11.0. I am able to use gemini, however, when gemini suggests changes, the diff view opens up within the same terminal as that of the gemini chat and not as a new tab as can be seen in the demo video added in repository. The following images describe the scenario that I am observing:
This image shows the first window that I get when gemini suggests code changes. I am explicitly asked if I want to accept changes or not or how I want to view the changes. This behaviour was not there in the demonstration video. Now when I select modify with an external editor option, I get this window . Here the diff view is opened in the same terminal where gemini is running. Can you help me debug this issue?

[gutsavgupta]

Hi, sorry for responding late, saw it just now,
can you check if gemini session is connected? you do /ide status in the gemini cli (

)

[shandilya1998]

The following is the output

[gutsavgupta]

I see, can you describe how are you opening gemini inside nvim session?
Ideally you should use the plugin command to do so, checkout the documentation on opening a gemini session from nvim session itself

Cmd: :GeminiSwitchToCli

[shandilya1998]

I am using the following configuration file. I use the <leader>-g-g keybinding to open nvim

-- lua/plugins/gemini.lua
return {
	{
		"gutsavgupta/nvim-gemini-companion",
		dependencies = {
			"nvim-lua/plenary.nvim",
			"ibhagwan/fzf-lua", -- Required for the custom UI select integration
		},
		event = "VeryLazy",
		config = function()
			local gemini = require("gemini")

			-- 1. Enable Fzf Support
			-- Override vim.ui.select to use fzf-lua for a better selection experience
			vim.ui.select = function(items, opts, onChoice)
				require('fzf-lua').fzf_exec(items, {
					prompt = opts.prompt or 'Select from items',
					actions = {
						['default'] = function(selected) onChoice(selected[1]) end,
					},
					winopts = { height = math.min(0.2 + #items * 0.05, 0.6) },
				})
			end

			-- 2. Setup Gemini
			gemini.setup({
				-- We only specify "gemini" as qwen is not installed in the Dockerfile
				cmds = { "gemini" }, 
				win = {
					preset = "floating", -- Default style: floating, right-fixed, left-fixed, bottom-fixed
					width = 0.8,
					height = 0.8,
				},
				-- Optional: Customize terminal mapping if needed
				on_buf = function(buf)
					-- Example: Add buffer-specific keys here if necessary
				end,
			})
		end,

		-- 3. Easy to Remember Keybindings (Prefix: <leader>g)
		keys = {
			-- Core Interface
			{ "<leader>gg", "<cmd>GeminiToggle<cr>", desc = "Gemini: Toggle Sidebar" },
			{ "<leader>gc", "<cmd>GeminiSwitchToCli<cr>", desc = "Gemini: Switch/Spawn Agent" },
			{ "<leader>gy", "<cmd>GeminiSwitchSidebarStyle<cr>", desc = "Gemini: Switch Sidebar Style" },

			-- Visual Selection Interaction
			{ 
				"<leader>gs", 
				function() 
					vim.cmd('normal! gv')
					vim.cmd("'<,'>GeminiSend")
				end, 
				mode = { 'x' }, 
				desc = 'Gemini: Send Selection to AI' 
			},

			-- Diagnostics & Debugging
			{ "<leader>gd", "<cmd>GeminiSendLineDiagnostic<cr>", desc = "Gemini: Explain Line Diagnostic" },
			{ "<leader>gD", "<cmd>GeminiSendFileDiagnostic<cr>", desc = "Gemini: Explain File Diagnostics" },

			-- Diff Management (Standard vim diff commands work, but these are explicit)
			{ "<leader>ga", "<cmd>GeminiAccept<cr>", desc = "Gemini: Accept Changes" },
			{ "<leader>gr", "<cmd>GeminiReject<cr>", desc = "Gemini: Reject Changes" },
		},
	}
}

Thus, I am using the command :GeminiToggle to start the cli.

[gutsavgupta]

I see, thanks for that info, I tested your config locally and it seems to be working fine for me,
we need to debug what's going wrong in your case, can you do the following?

1. start nvim like this NGC_LOG_LEVEL=debug nvim
2. check the output for :checkhealth gemini command? it should output something like this (share your output too)

open the gemini cli within nvim and share the :messages command output here. if the output is too large to copy, you can generally find the log file $HOME/.local/state/nvim/nvim-gemini-companion.log , share the file in that case

This following is the output of the checkhealt command:

I wonder if some of my other nvim configuration may be effecting this. However, I removed all other plugin files and checked and I still got the same behaviour. I have setup gemini-cli within a docker image and am using nvim within a container. I am not sure if that could be the problem here.

[gutsavgupta]

Right, at the moment running gemini and nvim on different containers won’t work. I would advise to run both of them on same host or same container

I am running them inside the same container only. Let me share the Dockerfile:

I have setup my nvim and gemini in the same container. I need to work on multiple devices and setting up each is a hassle so I have setup this docker image which i now use as my IDE.

[gutsavgupta]

That’s unusual — I’d have expected it to work. Here’s what happens behind the scenes:

• The Neovim Gemini plugin starts an MCP server and listens on a port (in your case, 42497).
  • You can confirm this anytime with the :checkhealth command.
• When triggered, the plugin spawns a Gemini CLI session with a few key environment variables:

GEMINI_CLI_IDE_SERVER_PORT=42497
GEMINI_CLI_IDE_WORKSPACE_PATH=/ws
TERM_PROGRAM=vscode

• If you open a terminal inside Neovim and run:

TERM_PROGRAM=vscode GEMINI_CLI_IDE_WORKSPACE_PATH=/ws GEMINI_CLI_IDE_SERVER_PORT=<port> gemini

it should connect with server
From your logs, though, Gemini CLI didn’t even try to connect — which is odd. This usually happens when one of the critical environment variables (server port or workspace path) isn’t being set or passed correctly. I would suggest running NGC_LOG_LEVEL=debug nvim and opening gemini along with --debug` flag to further see what's happening

[shandilya1998]

Does gemini have to be configured to provide or give json output to work with the plugin?

[shandilya1998]

Can you actually share the configuration of your gemini setup? maybe that could help. I will check other things too and share in this thread. Can you open this issue in the meanwhile? If some bugs comes out of this I can patch it up.

As you mentioned I tried running a new gemini instance from a terminal in nvim with the commands and you shared and I still got the same behaviour.
