+title: "My nvim/tmux workflow"
+date: 2024-03-04T21:44:00-05:00
+topics: [software development, neovim, tmux]
+---
+
+At my previous employment I was forced to use a windows system. 
+Although not ideal, I was able to continue using my Linux terminal workflows by heavily utilizing Windows Subsystem for Linux.
+As part of this I had to get comfortable with integrating tmux into my workflow as I didn't care to learn the Windows Terminal options for terminal multiplexing.
+I don't need tmux quite as much anymore since my current employer allows me run Linux on my development machine, but I still use it when remoting into my work desktop via ssh.
+Hopefully this can be of use in improving the efficiency of others that depend on terminal based workflows.
+
+## tmux setup 
+
+As a note, all of the below settings should be added to your `~/.tmux.conf` if you are interested in using them.
+### Some nice settings
+
+I wanted to start out with some nice settings for tmux that I generally like.
+First and foremost I remap the `send-prefix` key.
+
+```tmux
+unbind C-b
+set -g prefix C-p
+bind C-p send-prefix
+```
+
+I also rebind the pane splitting commands:
+
+```tmux
+bind | split-window -h -c "#{pane_current_path}"
+bind - split-window -v -c "#{pane_current_path}"
+unbind '"'
+unbind %
+```
+
+And finally, I enable vim key binds in scrolling mode
+
+```tmux
+set-window-option -g mode-keys vi
+bind-key -T copy-mode-vi v send -X begin-selection
+bind-key -T copy-mode-vi V send -X select-line
+bind-key -T copy-mode-vi y send -X copy-pipe-and-cancel 'xclip -in -selection clipboard'
+```
+### Integration with neovim
+
+Here by integration, I mean seamlessly transitioning between tmux and neovim splits.
+To do this we want tmux to figure out if the current tmux split contains a vim process (and potential vim splits).
+We then can then bind the same motion keys in tmux and nvim so that we can seamlessly move from a tmux split into a vim split and back all using the same keys!
+We can do this with the following code snippet in our `~/.tmux.conf`.
+
+```tmux
+is_vim="ps -o state= -o comm= -t '#{pane_tty}' \
+    | grep -iqE '^[^TXZ ]+ +(\\S+\\/)?g?(view|n?vim?x?)(diff)?$'"
+
+bind-key -n C-h  if-shell  "$is_vim"  "send-keys C-h"  "select-pane -L"
+bind-key -n C-j   if-shell  "$is_vim"  "send-keys C-j"   "select-pane -D"
+bind-key -n C-k  if-shell  "$is_vim"  "send-keys C-k"  "select-pane -U"
+bind-key -n C-l   if-shell  "$is_vim"  "send-keys C-l"   "select-pane -R"
+bind-key -n C-\   if-shell  "$is_vim"  "send-keys C-\\"  "select-pane -l"
+```
+
+`is_vim` defines a command to determine whether the current pane is running vim. 
+If so, we send the key codes directly to vim, otherwise process the key binding with tmux.
+For this case we utilize `<C-{vim_keys}>` for motion to make things easy.
+
+## Neovim setup
+
+Now we need to make sure we can go from a neovim split smoothly to a tmux split.
+To do this we utilize the [christoomey/vim-tmux-navigator](https://github.com/christoomey/vim-tmux-navigator) plugin.
+First add it to your plugin manager,
+
+**Lazy.nvim:**
+```
+require("lazy").setup({
+    "christoomey/vim-tmux-navigator"
+})
+```
+
+or **Vim-plug:**
+
+```
+call plug#begin('~/.vim/plugged')
+    Plug 'christoomey/vim-tmux-navigator'
+call plug#end()
+```
+
+and that's it! 
+It should automatically add the `<C-{vim_keys}>` for motion and handle moving out of vim splits to tmux panes.
+Hopefully this is useful to someone else!
+
+## Bonus
+
+Gruvbox is everywhere even [tmux gets a nice theme](https://github.com/egel/tmux-gruvbox).
