Key bindings to send lines of test code with tmux+vim?

问题

I am trying to create an ide-like setup with tmux + vim. I've seen a lot written about this on the internet, but I've been unable to figure out how to do one critical thing: execute test lines of code.

For example, you may create a tmux session with a vim pane for writing code and a python pane for executing tests, like so:

# Create a new Tmux session.
session="ide"
tmux start-server
tmux new-session -d -s $session -n ide

# Split the pane horizontally and launch vim.
tmux selectp -t 1
tmux splitw -v -p 50
tmux selectp -t 1
tmux send-keys "vim" C-m

# Enter insert mode and start coding...
tmux send-keys "i"
tmux send-keys "print('hello world')" C-m

# Select the second pane and launch python.
tmux selectp -t 2
tmux send-keys "python" C-m

# Attach to tmux session.
tmux attach -t ide

So, I am aware of how you might use tmux send-keys or tmux's command mode (<prefix> :) to send commands to another pane. However, I'd like to make a vim key binding that copies whatever line I'm on and sends this to the opposite pane in a couple of quick keystrokes.

If you have some magic sauce, I'd be grateful if you could share!

I think https://github.com/jpalardy/vim-slime is what you are be looking for.

Once installed and configured (tmux is not the default used, screen is), you can execute the text under the cursor with <C-c><C-c>.

The following worked for me:

Install Vim-slime. I'm using Vundle, so I added the following to my .vimrc:
Plugin 'jpalardy/vim-slime', and ran :PluginInstall in vim.
Configure slime for tmux by adding the following to your .vimrc:
let g:slime_target = "tmux"
Try sending a line with vim-slime with the default key-binding (C-c C-c). Vim-Slime should prompt you for Tmux's socket and target pane. I found Tmux's socket with:
echo $TMUX | cut -f1 -d','.
Alternatively, you can use :SlimeConfig.
Now it's working!
