Tmux Suspend

Plugin that lets you suspend local tmux session, so that you can work with nested remote tmux session painlessly.

Demo:

Usage

With the default keybinding,

Press F12 to suspend your local tmux session. In suspeded state, you can only interact with the currently active pane (which will be running the remote tmux session).

Press F12 again in suspended state to resume local tmux session.

Note: If you have tmux-mode-indicator plugin installed, it'll automatically show indicator for the suspended state.

Installation

Installation with Tmux Plugin Manager

Add this repository as a TPM plugin in your .tmux.conf file:

set -g @plugin 'MunifTanjim/tmux-suspend'

Press prefix + I in Tmux environment to install it.

Manual Installation

Clone this repository:

git clone https://github.com/MunifTanjim/tmux-suspend.git ~/.tmux/plugins/tmux-suspend

Add this line in your .tmux.conf file:

run-shell ~/.tmux/plugins/tmux-suspend/suspend.tmux

Reload Tmux configuration file with:

tmux source-file ~/.tmux.conf

Configuration Options

The following configuration options are available:

@suspend_key

Key used to suspend/resume local tmux session. This is not binded to any Prefix.

set -g @suspend_key 'F12'

@suspend_suspended_options

Comma-seperated list of items denoting options to set for suspended state. These options will be automatically reverted when session is resumed.

set -g @suspend_suspended_options " \
  @mode_indicator_custom_prompt:: ---- , \
  @mode_indicator_custom_mode_style::bg=brightblack\\,fg=black, \
"

The syntax of each item is #{option_name}:#{option_flags}:#{option_value}.

Item Segment	Description
#{option_name}	name of the option.
#{option_flags}	flags accepted by set-option, can be left empty.
#{option_value}	value of the option, commas (,) inside value need to be escaped as \\,

For example:

# remove colors from status line for suspended state
set -g @suspend_suspended_options " \
  status-left-style::bg=brightblack\\,fg=black bold dim, \
  window-status-current-style:gw:bg=brightblack\\,fg=black, \
  window-status-last-style:gw:fg=brightblack, \
  window-status-style:gw:bg=black\\,fg=brightblack, \
  @mode_indicator_custom_prompt:: ---- , \
  @mode_indicator_custom_mode_style::bg=brightblack\\,fg=black, \
"

@suspend_on_suspend_command and @suspend_on_resume_command

These options can be set to arbritary commands to run when session is suspended (@suspend_on_suspend_command) or resumed (@suspend_on_resume_command).

set -g @suspend_on_resume_command ""
set -g @suspend_on_suspend_command ""

For example, you can do the same thing that the default value of @suspend_suspended_options does using these options instead:

set -g @suspend_suspended_options ""

set -g @suspend_on_resume_command "tmux \
  set-option -uq '@mode_indicator_custom_prompt' \\; \
  set-option -uq '@mode_indicator_custom_mode_style'"

set -g @suspend_on_suspend_command "tmux \
  set-option -q '@mode_indicator_custom_prompt' ' ---- ' \\; \
  set-option -q '@mode_indicator_custom_mode_style' 'bg=brightblack,fg=black'"

As you can see, it's more convenient to use @suspend_suspended_options for setting and reverting options.
