TMUX FZF Session Switch

Video demo

QnA

Features:

1. Fuzzy search and switch sessions and windows.
2. Create new sessions.

What are the reasons not to use this plugin?

1. tmux-fzf have more black magic.
2. tmux-fzf have single shortcut for switch session and many function tmux-fzf had.

What are the reasons for using this plugin?

This plugin offers a single shortcut for switching between sessions, windows, and creating new sessions.

This creates a simple workflow: "I want to go to [session/window name], press the shortcut, type the name, and press enter. Done!"

Or:

"I want to go to [session/window name], press the shortcut, type the name. Uh oh, it doesn't exist. Okay, press enter to create a new session with that name."

Plan

Blazingly fast Tmux workflow, built muscle memory, better developer experience.

Not in plan

Having multiple features like tmux-fzf

Requirements

• Tmux >= 3.3a (for the pop-up menu feature)
• fzf

Getting Started

1. Install the Tmux Plugin Manager (TPM):

   Follow the instructions at https://github.com/tmux-plugins/tpm to install TPM.

2. Add the Plugin to Your Tmux Config:

   Add the following line to your ~/.tmux.conf file:

   set -g @plugin 'vndmp4/tmux-fzf-session-switch'
   

3. Install the Plugin:

   Use TPM to install the plugin. By default, you can press prefix + I (where prefix is your tmux prefix key, usually Ctrl + b, and I is Shift + i).

4. Open FZF for Session Switching:

   Press prefix + Ctrl + f to open FZF in a new tab. (For example, if your prefix is Ctrl + b, hold Ctrl, press b, then press f).

5. Creating New Sessions:

   If you type a session name that doesn't exist, you will be prompted to create it.

   • Handling Name Conflicts: If the name conflicts with an existing session, enclose it in double or single quotes (e.g., 'example').

Customize

🫰Thanks to @erikw and adia-dev

Search session only

set-option -g @fzf-goto-session-only 'true'

Key binding

set -g @fzf-goto-session 'key binding'

Eg. to override the default session switcher in tmux available at prefix + s:

set -g @fzf-goto-session 's'

Without prefix

set -g @fzf-goto-session-without-prefix 'true'

Window dimensions

set -g @fzf-goto-win-width WIDTH
set -g @fzf-goto-win-height HEIGHT

Eg.

set -g @fzf-goto-win-width 70
set -g @fzf-goto-win-height 20

Preview window on the side

Enable this option

set -g @fzf-goto-preview-enabled 'true'

Custom

set-g @fzf-goto-preview-width-preview WIDTH
set-g @fzf-goto-preview-height-preview HEIGH

Tips

Using in the Command Line

function tmux_session_switch() {
  session=$(tmux list-windows -a | fzf | sed 's/: .*//g')
  tmux switch-client -t "$session"
}

function tmux_kill_uname_session() {
  echo "kill all unname tmux session"
  cd /tmp/
  tmux ls | awk '{print $1}' | grep -o '[0-9]\+' >/tmp/killAllUnnameTmuxSessionOutput.sh
  sed -i 's/^/tmux kill-session -t /' killAllUnnameTmuxSessionOutput.sh
  chmod +x killAllUnnameTmuxSessionOutput.sh
  ./killAllUnnameTmuxSessionOutput.sh
  cd -
  tmux ls
}

Using this with the clear command is effective:

alias clear='tmux_kill_uname_session ; clear -x'
