Create and manage tmux sessions easily. Inspired by Jon Druse's (Screeninator) and Arthur Chiu's (Terminitor)




$ gem install tmuxinator

Editor and Shell

tmuxinator uses your shell's default editor for opening files. If you're not sure what that is type:

$ echo $EDITOR

For me that produces "mate -w" If you want to change your default editor simple put a line in ~/.bashrc that changes it. Mine looks like this:

export EDITOR='mate -w'

Environment Integration

Add this to your ~/.bashrc (or similar)

[[ -s $HOME/.tmuxinator/scripts/tmuxinator ]] && source $HOME/.tmuxinator/scripts/tmuxinator


Create a project

$ tmuxinator new project_name

Create or edit your projects with this command, for editing you can also use tmuxinator open project_name. new aliased to o,open and n. Your default editor ($EDITOR) is used to open the file. If this is a new project you will see this default config:

# ~/.tmuxinator/project_name.yml
# you can make as many tabs as you wish...

project_name: Tmuxinator
project_root: ~/code/rails_project
rvm: 1.9.2@rails_project
pre: sudo /etc/rc.d/mysqld start
  - editor:
      layout: main-vertical
        - vim
        - #empty, will just run plain bash
        - top
  - shell: git pull
  - database: rails db
  - server: rails s
  - logs: tail -f logs/development.log
  - console: rails c
  - capistrano:
  - server: ssh me@myhost

If a tab contains multiple commands, they will be 'joined' together with '&&'. If you want to have your own default config, place it into $HOME/.tmuxinator/default.yml

The pre command allows you to run anything before starting the tmux session. Could be handy to make sure you database daemons are running. Multiple commands can be specified, just like for tabs.

Panes Support

you can define your own panes inside a window likes this:

- window_with_panes
    layout: main-vertical
      - vim
      - #empty, will just run plain bash
      - top

Starting a project

$ start_[project_name]


You can also use this shorthand alias for tmuxinator

$ mux [command/project_name]

This will fire up tmux with all the tabs you configured.

Other Commands

$ tmuxinator copy existing_project new_project

Copy an existing project. aliased to c

$ tmuxinator list

List all the projects you have configured. aliased to l

$ tmuxinator delete project_name

Remove a project

$ tmuxinator implode

Remove all tmuxinator configs, aliases and scripts. aliased to i

$ tmuxinator doctor

Examines your environment and identifies problems with your configuration

$ tmuxinator version

$ tmuxinator help

shows tmuxinator's help. aliased to h

Contributing to tmuxinator

  • Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet
  • Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it
  • Fork the project
  • Start a feature/bugfix branch
  • Commit and push until you are happy with your contribution
  • Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
  • Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
