Tmux current pane hostname/user

Tmux plugin that enables displaying hostname and user of the current pane in your status bar.

Important

Replaces the #H default format variable

Usage

Basics

• #H (#{hostname}) will be the hostname of your current path
• #{hostname_short} will be the short hostname of your current path (up to the first dot)
• #U (#{username}) will be current user name

Remote connection info

Plugin can detect pane has remote shell connection in several states:

• ssh session inside pane
• running docker (or podman) container

In both cases, #{hostname} and #{username} with show their values relatively to that state.

Besides #{hostname} and #{username} there are more usefull format variables:

• #{pane_ssh_port} will show the connection port, otherwise it will be empty.
• #{pane_ssh_connected} will be set to 1 if the currently selected pane has an active connection. (Useful for #{?#{pane_ssh_connected},ssh,no-ssh} which will evaluate to ssh if there is an active remote session in the currently selected pane and no-ssh otherwise.)
• #{pane_ssh_connect} if an open remote session exists will show the connection info in "username@hostname:port" format, otherwise it will be empty.

Example

set -g status-left " #[bg=blue]#U#[bg=red]@#H#{?#{pane_ssh_port},:#{pane_ssh_port},}#[default] "

Installation with Tmux Plugin Manager (recommended)

Add plugin to the list of TPM plugins in .tmux.conf:

set -g @plugin "soyuka/tmux-current-pane-hostname"

Hit prefix + I to fetch the plugin and source it.

#U@#H interpolation should now take the current pane ssh status into consideration.

Manual Installation

Clone the repo:

$ git clone https://github.com/soyuka/tmux-current-pane-hostname ~/clone/path

Add this line to the bottom of .tmux.conf:

run-shell ~/clone/path/current_pane_hostname.tmux

Reload TMUX environment:

# type this in terminal
$ tmux source-file ~/.tmux.conf

#U@#H interpolation should now work.

Todo

• implement templating for #{pane_ssh_connect}

Limitations

• only named running container may be defined, otherwise it would be ignored
