* Presentation
  :PROPERTIES:
  :CUSTOM_ID: Presentation-0b37c6c0
  :END:
  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 [[https://github.com/gpakosz/.tmux][here]].

* Windows and pane creation
  :PROPERTIES:
  :CUSTOM_ID: Windows_and_pane_creation-66275518
  :END:
  Whether if a new *window* will retain the current path. Possible values are:
  - true
  - false (default)
  #+BEGIN_SRC conf-unix
  tmux_conf_new_window_retain_current_path=true
  #+END_SRC

  Whether if a new *pane* should retain the current path. Possible values are:
  - true (default)
  - false
  #+BEGIN_SRC conf-unix
  tmux_conf_new_window_retain_current_path=true
  #+END_SRC

  Whether or  not tmux should attempt  to reconnect to the  current ssh session.
  This is still experimental. Possible values are:
  - true
  - false (default)
  #+BEGIN_SRC conf-unix
  tmux_conf_new_pane_reconnect_ssh=true
  #+END_SRC

  Whether  tmux should  prompt for  new session  name when  creating a  new one.
  Possible values are:
  - true
  - false (default)
  #+BEGIN_SRC conf-unix
  tmux_conf_new_session_prompt=false
  #+END_SRC

* Display
  :PROPERTIES:
  :CUSTOM_ID: Display-d5ae1908
  :END:
  Whether to activate RGB 24-bit color  support (only available in tmux >= 2.2).
  Possible values are:
  - true
  - false (default)
  #+BEGIN_SRC conf-unix
  tmux_conf_theme_24b_colour=false
  #+END_SRC

  These variables are for chosing the window style. I use the default one.
  #+BEGIN_SRC conf-unix
    tmux_conf_theme_window_fg='default'
    tmux_conf_theme_window_bg='default'
  #+END_SRC

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

  - false (default)
  #+BEGIN_SRC conf-unix
    tmux_conf_theme_highlight_focused_pane=false
  #+END_SRC

  Set the terminal title. Built-in variables are:
  - =#{circled_window_index}=

  - =#{username}=
  - =#{username_ssh}=
  #+BEGIN_SRC conf-unix
    tmux_conf_theme_terminal_title='#h ❐ #S ● #I #W'
  #+END_SRC

  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.
  #+BEGIN_SRC conf-unix
    tmux_conf_theme_left_separator_main='\uE0B0'
    tmux_conf_theme_left_separator_sub='\uE0B1'
    tmux_conf_theme_right_separator_main='\uE0B2'

  #+END_SRC

** Colors and style
   :PROPERTIES:
   :CUSTOM_ID: Display-Colors_and_style-0994a014
   :END:
   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
   #+BEGIN_SRC conf-unix
   tmux_conf_theme_pane_border_style=thin
   #+END_SRC

   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_pane_border='#444444'
     tmux_conf_theme_pane_active_border='#00afff'
   #+END_SRC

   With these variables, you can set the colors for the pane indicators.
   #+BEGIN_SRC conf-unix
     tmux_conf_theme_pane_indicator='#00afff'
     tmux_conf_theme_pane_active_indicator='#00afff'
   #+END_SRC

   These variables set the colors and the style of the status line.
   #+BEGIN_SRC conf-unix
     tmux_conf_theme_message_fg='#000000'
     tmux_conf_theme_message_bg='#ffff00'
     tmux_conf_theme_message_attr='bold'
   #+END_SRC

   Same as above for the status line command style.
   #+BEGIN_SRC conf-unix
     tmux_conf_theme_message_command_fg='#ffff00'
     tmux_conf_theme_message_command_bg='#000000'
     tmux_conf_theme_message_command_attr='bold'

* User customizations
  :PROPERTIES:
  :CUSTOM_ID: User_customizations-c913b5d7
  :END:
  Here we can override  or undo some setting from settings  from tmux. First, we
  can increase the history size.
  #+BEGIN_SRC conf-unix
    set -g history-limit 10000
  #+END_SRC

  We can also start with mouse mode enabled. But I don’t.
  #+BEGIN_SRC conf-unix
    #set -g mouse on
  #+END_SRC

  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.
  #+BEGIN_SRC conf-unix
    #set -g status-keys vi
    #set -g mode-keys vi
  #+END_SRC

  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.
  #+BEGIN_SRC conf-unix
    # set -gu prefix2
    # unbind C-a
    # unbind C-b
    # set -g prefix C-a
    # bind C-a send-prefix
  #+END_SRC

  Move the status line to the top.
  #+BEGIN_SRC conf-unix
    #set -g status-position top
  #+END_SRC
