Presentation

I don’t really use tmux often, but I certainly do like a nice presentation and useful features, hence this configuration. This config file is inspired by gpakosz’s tmux configuration repo you can find here.

Windows and pane creation

Whether if a new window will retain the current path. Possible values are:

true
false (default)

tmux_conf_new_window_retain_current_path=true

Whether if a new pane should retain the current path. Possible values are:

true (default)
false

tmux_conf_new_window_retain_current_path=true

Whether or not tmux should attempt to reconnect to the current ssh session. This is still experimental. Possible values are:

true
false (default)

tmux_conf_new_pane_reconnect_ssh=true

Whether tmux should prompt for new session name when creating a new one. Possible values are:

true
false (default)

tmux_conf_new_session_prompt=false

Display

Whether to activate RGB 24-bit color support (only available in tmux >= 2.2). Possible values are:

true
false (default)

tmux_conf_theme_24b_colour=false

These variables are for chosing the window style. I use the default one.

  tmux_conf_theme_window_fg='default'
  tmux_conf_theme_window_bg='default'

Whether the focused pane should be highlighted (only available in tmux >= 2.1). Possible values are:

true
false (default)

  tmux_conf_theme_highlight_focused_pane=false

Set the terminal title. Built-in variables are:

#{circled_window_index}
#{circled_session_name}
#{hostname}
#{hostname_ssh}
#{username}
#{username_ssh}

  tmux_conf_theme_terminal_title='#h ❐ #S ● #I #W'

These variables set the left/right separators between sections. With the current values, you don’t need to install Powerline, but only fonts patched with Powerline symbols or the standalone PowerlineSymbols.otf font.

  tmux_conf_theme_left_separator_main='\uE0B0'
  tmux_conf_theme_left_separator_sub='\uE0B1'
  tmux_conf_theme_right_separator_main='\uE0B2'
  tmux_conf_theme_right_separator_sub='\uE0B3'

Colors and style

Colors displayed in tmux can be chosen thanks to the following variables. Any color should be formatted as a hexadecimal RGB value preceded by a pound sign # (e.g. #00afff for light blue) or default to let our terminal set it for us.

Choose the style of the pane borders. Possible values are:

thin (default)
fat

tmux_conf_theme_pane_border_style=thin

Declare what the colors of the focused pane should be. The first variable specifies the foreground color, the other the background color.

  tmux_conf_theme_focused_pane_fg='default'

Here you can set the colors of the pane borders.

  tmux_conf_theme_pane_border='#444444'
  tmux_conf_theme_pane_active_border='#00afff'

With these variables, you can set the colors for the pane indicators.

  tmux_conf_theme_pane_indicator='#00afff'
  tmux_conf_theme_pane_active_indicator='#00afff'

These variables set the colors and the style of the status line.

  tmux_conf_theme_message_fg='#000000'
  tmux_conf_theme_message_bg='#ffff00'
  tmux_conf_theme_message_attr='bold'

Same as above for the status line command style.

Clipboard

Whether if in copy mode, copying the selection also copies to the OS clipboard. Possible values are:

true

  tmux_conf_copy_to_os_clipboard=false

User customizations

Here we can override or undo some setting from settings from tmux. First, we can increase the history size.

  set -g history-limit 10000

We can also start with mouse mode enabled. But I don’t.

  #set -g mouse on

Whether or not Vi mode should be enabled. But really, we should rather export the VISUAL or EDITOR environment variables, see the tmux manual. Although I don’t, as said in my dotfish, I prefer to use Emacs.

  #set -g status-keys vi
  #set -g mode-keys vi

Replace C-b by C-a instead of using both prefixes. I personally prefer to just use C-b, hence why the lines are commented.

  # set -gu prefix2
  # unbind C-a
  # unbind C-b
  # set -g prefix C-a
  # bind C-a send-prefix

Move the status line to the top.

  #set -g status-position top
