Tmux
====

Defines [tmux][1] aliases and provides for auto launching it at start-up.

Settings
--------

### Auto-Start

Starts a tmux session automatically when Zsh is launched.

To enable this feature when launching Zsh in a local terminal, add the
following line to *zpreztorc*:

```sh
zstyle ':prezto:module:tmux:auto-start' local 'yes'
```

To enable this feature when launching Zsh in a SSH connection, add the
following line to *zpreztorc*:

```sh
zstyle ':prezto:module:tmux:auto-start' remote 'yes'
```

In both cases, it will create a background session named _prezto_ if the tmux
server is not started.

You can change the default session name with:

```sh
zstyle ':prezto:module:tmux:session' name '<YOUR DEFAULT SESSION NAME>'
```

With `auto-start` enabled, you may want to control how multiple sessions are
managed. The `destroy-unattached` option of tmux controls if the unattached
sessions must be kept alive, making sessions available for later use, configured
in *tmux.conf*:

```conf
set-option -g destroy-unattached [on | off]
```

#### iTerm2 Integration

[iTerm2][6] offers significant integration with tmux. This can be enabled by
adding the following line to *zpreztorc*:

```sh
zstyle ':prezto:module:tmux:iterm' integrate 'yes'
```

Read [iTerm2 and tmux Integration][7] for more information.

Aliases
-------

  - `tmuxa` attaches or switches to a tmux session.
  - `tmuxl` lists sessions managed by the tmux server.

Caveats
-------

On macOS, launching tmux can cause the error **launch_msg(...): Socket is not
connected** to be displayed, which can be fixed by installing
[reattach-to-user-namespace][3], available in [Homebrew][4], and adding the
following to *tmux.conf*:

```conf
set-option -g default-command "reattach-to-user-namespace -l $SHELL -l"
```

Furthermore, tmux is known to cause **kernel panics** on macOS. A discussion
about this and Prezto has already been [opened][2].
