Create and manage tmux sessions easily.
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:
For me that produces "vim" If you want to change your default editor simply put a line in ~/.bashrc that changes it. Mine looks like this:
The recommended version of tmux to use is 1.8. Your mileage may vary for earlier versions. Refer to the FAQ for any odd behaviour.
If you use a
base-index other than the default, please be sure to also set the
set-window-option -g pane-base-index 1
Download the appropriate completion file from the repo and
source the file.
The following are example where the completion file has been downloaded into
Add the following to your
Add the following to your
tmuxinator.fish to your
cp ~/.bin/tmuxinator.fish ~/.config/fish/completions/
A working knowledge of tmux is assumed. You should understand what windows and panes are in tmux. If not please consult the man pages for tmux.
Create a project
Create or edit your projects with:
tmuxinator new [project]
For editing you can also use
tmuxinator open [project].
new is aliased to
n. Please note that dots can't be used in project
names as tmux uses them internally to delimit between windows and panes.
Your default editor (
$EDITOR) is used to open the file.
If this is a new project you will see this default config:
# ~/.tmuxinator/sample.yml name: sample root: ~/ # Optional. tmux socket # socket_name: foo # Runs before everything. Use it to start daemons etc. # pre: sudo /etc/rc.d/mysqld start # Runs in each window and pane before window/pane specific commands. Useful for setting up interpreter versions. # pre_window: rbenv shell 2.0.0-p247 # Pass command line options to tmux. Useful for specifying a different tmux.conf. # tmux_options: -f ~/.tmux.mac.conf # Change the command to call tmux. This can be used by derivatives/wrappers like byobu. # tmux_command: byobu # Specifies (by name or index) which window will be selected on project startup. If not set, the first window is used. # startup_window: logs windows: - editor: layout: main-vertical panes: - vim - guard - server: bundle exec rails s - logs: tail -f log/development.log
The windows option allows the specification of any number of tmux windows. Each window is denoted by a YAML array entry, followed by a name and command to be run.
windows: - editor: vim
Window specific root
An optional root option can be specified per window:
name: test root: ~/projects/company windows: - small_project: root: ~/projects/company/small_project panes: - start this - start that
This takes precedence over the main root option.
Note that if you wish to use panes, make sure that you do not have
. in your project name. tmux uses
. to delimit between window and pane indices,
and tmuxinator uses the project name in combination with these indices to target the correct pane or window.
Panes are optional and are children of window entries, but unlike windows, they do not need a name. In the following example, the
editor window has 2 panes, one running vim, the other guard.
windows: - editor: layout: main-vertical panes: - vim - guard
Interpreter Managers & Environment Variables
To use tmuxinator with rbenv, RVM, NVM etc, use the
pre_window: rbenv shell 2.0.0-p247
These command(s) will run before any subsequent commands in all panes and windows.
Custom attachment and post commands
You can set tmuxiniator to skip auto-attaching to the session by using the
You can also run arbitrary commands by using the
post option. This is useful if you want to attach to tmux in a non-standard way (e.g. for a program that makes use of tmux control mode like iTerm2).
post: tmux -CC attach
Passing directly to send-keys
tmuxinator passes commands directly to send keys. This differs from simply chaining commands together using
;, in that
tmux will directly send the commands to a shell as if you typed them in. This allows commands to be executed on a remote server over
SSH for example.
To support this both the window and pane options can take an array as an argument:
name: sample root: ~/ windows: - stats: - ssh email@example.com - tail -f /var/log/stats.log - logs: layout: main-vertical panes: - logs: - ssh firstname.lastname@example.org - cd /var/logs - tail -f development.log
Project files support ERB for reusability across environments. Eg:
root: <%= ENV["MY_CUSTOM_DIR"] %>
Starting a session
This will fire up tmux with all the tabs and panes you configured.
tmuxinator start [project] [alias]
If you use the optional
[alias] argument, it will start a new tmux session
with the custom alias name provided. This is to enable reuse of a project
without tmux session name collision.
A shorthand alias for tmuxinator can also be used.
