如何实现Vim命令：退出后在新tmux会话打开当前文件

Hey there! Let's tackle this problem step by step. You want a custom Vim command that quits Vim, then automatically launches a new tmux session, switches to Vim's original working directory, and opens the current file in a fresh Vim instance. Here are two solid approaches tailored to your needs:

Method 1: Direct Vimrc Command (No Shell Config Changes) #

This approach creates a self-contained Vim command that sets up the tmux session in the background before quitting Vim.

Add this line to your ~/.vimrc:

command! TmuxOpen execute "silent !tmux new-session -d -s vim_session 'cd " . shellescape(getcwd()) . " && vim " . shellescape(expand('%:p')) . "'" | quit

Let's break down what each part does:

• command! TmuxOpen: Creates a custom command named TmuxOpen (the ! overwrites any existing command with the same name).
• shellescape(getcwd()): Safely escapes your current working directory—critical for handling spaces or special characters in paths.
• shellescape(expand('%:p')): Grabs the absolute path of your open file and escapes it to avoid shell errors.
• tmux new-session -d -s vim_session: Spins up a detached tmux session named vim_session (the -d flag keeps it running in the background so Vim doesn't hang).
• silent !: Runs the shell command quietly, skipping the annoying "Press ENTER to continue" prompt.
• | quit: Exits Vim immediately after triggering the tmux session.

How to use it: #

1. Open test.c in Vim
2. Run :TmuxOpen
3. Vim will quit—then just run this command to jump into your new tmux session:

   tmux attach -t vim_session
   

Method 2: Vim + Shell Function (Auto-Attach After Quitting) #

If you want a completely seamless experience (no extra tmux attach command), this method uses environment variables and a shell function to auto-launch the tmux session right after Vim exits.

Step 1: Add to your ~/.vimrc #

command! TmuxOpen let $TMUX_TARGET_FILE = expand('%:p') | let $TMUX_TARGET_CWD = getcwd() | quit

This stores your file path and working directory in temporary environment variables, then quits Vim.

Step 2: Add a shell function to ~/.bashrc (or ~/.zshrc for Zsh) #

vim() {
  # Run the regular Vim command
  command vim "$@"
  
  # Check if Vim set our target variables before exiting
  if [[ -n "$TMUX_TARGET_FILE" && -n "$TMUX_TARGET_CWD" ]]; then
    # Create a new tmux session, switch to the saved directory, and open the file
    tmux new-session -c "$TMUX_TARGET_CWD" -s vim_session "vim $TMUX_TARGET_FILE"
    # Clear the variables so they don't trigger accidentally later
    unset TMUX_TARGET_FILE TMUX_TARGET_CWD
  fi
}

How to use it: #

1. Restart your shell (or run source ~/.bashrc) to load the function
2. Open test.c with vim test.c
3. Run :TmuxOpen inside Vim
4. Vim will quit, and a new tmux session will automatically open with test.c loaded in Vim!

Quick Notes: #

• If you already have a tmux session named vim_session, the command will fail. To fix this, use a unique session name (e.g., vim_session_$(date +%s) for a timestamped name).
• Always use shellescape for paths—it prevents crashes from spaces, parentheses, or special characters in file/directory names.
