Nvim cannot change window to Tmux, output of :TmuxNavigatorProcessList is not as displayed

[ctagard]

Here is the output of :TmuxNavigatorProcessList:

Ss -zsh
S+ nvim

I am running on MacOS 13.5.2, Nvim v0.9.2, Tmux 3.3a. I checked that there were no conflicting keymaps, but when I change to my neovim window I cannot navigate to back to my terminal window.

Just confirming, can you share the output of :verbose nmap <C-j> in vim, and tmux list-keys | grep C-j in your terminal?

I have the same problem, I can't navigate from nvim (version NVIM v0.10.0-dev) to a tmux terminal.

verbose nmap <C-j>

tmux list-keys | grep C-j

from a Tmux terminal to nvim works appropriately.

In my case, I'm on Windows 11 + WSL

I am currently facing the same issue. Looks like an update broke it.
MacOS 13.4.1, NVIM v0.9.2, tmux 3.3a

n * j
Go to lower window
Last set from Lua

And

bind-key -T copy-mode-vi C-j select-pane -D
bind-key -T root C-j if-shell "ps-o state= -o comm=-t '#{pane_tty}' ... looks like the command from the install.

Seems related to this issue: LazyVim/LazyVim#1502

I've fixed it by setting up the following keymap in keymaps.lua:

local map = vim.keymap.set

-- vim-tmux-navigator
if os.getenv("TMUX") then
  map("n", "<C-h>", "<cmd>TmuxNavigateLeft<cr>")
  map("n", "<C-j>", "<cmd>TmuxNavigateDown<cr>")
  map("n", "<C-k>", "<cmd>TmuxNavigateUp<cr>")
  map("n", "<C-l>", "<cmd>TmuxNavigateRight<cr>")
end

You can also add event: "BufReadPre" to resolve the issue:

return {
  "christoomey/vim-tmux-navigator",
  event = "BufReadPre",
}

[ragnarok22]

event = "BufReadPre",

I recently migrated from Packer to Lazy and that trigger event fixed the problem for me. Thank you!

return {
  "christoomey/vim-tmux-navigator",
  event = "BufReadPre",
}

This solution only worked for me when opening up nvim first then selecting a file. Wouldn't work if opening a file with nvim directly. Adding the keymaps instead worked in both cases.

Sorry I'm a little new to all of this, where would I be adding this? I currently have a .config/nvim/lua/custom/plugins.lua that looks like this:

local plugins = {
  {
    "christoomey/vim-tmux-navigator",
    event = "BufReadPre",
    cmd = {
      "TmuxNavigateLeft",
      "TmuxNavigateDown",
      "TmuxNavigateUp",
      "TmuxNavigateRight",
      "TmuxNavigatePrevious",
    },
    keys = {
      { "<c-h>", "<cmd><C-U>TmuxNavigateLeft<cr>" },
      { "<c-j>", "<cmd><C-U>TmuxNavigateDown<cr>" },
      { "<c-k>", "<cmd><C-U>TmuxNavigateUp<cr>" },
      { "<c-l>", "<cmd><C-U>TmuxNavigateRight<cr>" },
      { "<c-\\>", "<cmd><C-U>TmuxNavigatePrevious<cr>" },
    },
  }
}

return plugins

And in my chadrc.lua I have M.plugins = "custom.lua" but this doesn't seem to fix my issue of not being able to navigate from Neovim to the tmux panel. Let me know what I'm doing wrong, thank you

[PierrickGT]

@jaikb in plugins.lua, you should have { "christoomey/vim-tmux-navigator", event = "BufReadPre" },

And the keys should be written in another file like keymaps.lua with this kind of config:

local map = vim.keymap.set

if os.getenv("TMUX") then
  map("n", "<C-h>", "<cmd>TmuxNavigateLeft<cr>")
  map("n", "<C-j>", "<cmd>TmuxNavigateDown<cr>")
  map("n", "<C-k>", "<cmd>TmuxNavigateUp<cr>")
  map("n", "<C-l>", "<cmd>TmuxNavigateRight<cr>")
end

  map("n", "<C-l>", "<cmd>TmuxNavigateRight<cr>")
end

Thank you for the response @PierrickGT. I went ahead and changed my line in my plugins.lua to just { "christoomey/vim-tmux-navigator", event = "BufReadPre" } and then made a new file called keymaps.lua with the code you provided. That didn't fix my issue though. Do I have to create a new mapping then pass that in my chadrc.lua for it to work? I tried something like that earlier too and that didn't seem to work either.

[avargas05]

@jaikb Here's what worked for me:

in ~/.config/nvim/lua/plugins/tmux.lua

return {
      "christoomey/vim-tmux-navigator",
}

Adding event = "BufReadPre" on my setup would break it again, so I keep it off.

in ~/.config/nvim/lua/config/keymaps.lua

-- Keymaps are automatically loaded on the VeryLazy event
-- Default keymaps that are always set: https://github.com/LazyVim/LazyVim/blob/main/lua/lazyvim/config/keymaps.lua
-- Add any additional keymaps here

local map = vim.keymap.set

-- vim-tmux-navigator
if os.getenv("TMUX") then
  map("n", "<C-h>", "<cmd>TmuxNavigateLeft<cr>")
  map("n", "<C-j>", "<cmd>TmuxNavigateDown<cr>")
  map("n", "<C-k>", "<cmd>TmuxNavigateUp<cr>")
  map("n", "<C-l>", "<cmd>TmuxNavigateRight<cr>")
end

return {}

If these lines aren't working for you then it's either because you have it in ~/.config/nvim/lua/custom rather than ~/.config/nvim/lua/plugins or ~/.config/nvim/lua/config. I'm not sure what you're trying to do with it in chadrc.lua but it shouldn't need it there in order to work.
