Setup

Turn on mouse

set -g mouse on

Start windows and panes at 1, not 0

set -g base-index 1
setw -g pane-base-index 1

Set up proper colors, using either screen or tmux-256-color depending on the terminal

## set the default TERM
set -g default-terminal screen
## update the TERM variable of terminal emulator when creating a new session or attaching a existing session
set -g update-environment 'DISPLAY SSH_ASKPASS SSH_AGENT_PID SSH_CONNECTION WINDOWID XAUTHORITY TERM'
## determine if we should enable 256-colour support
if "[[ ${TERM} =~ 256color ]]" 'set -g default-terminal screen-256color'

Keys

Set the prefix key to be C-a instead of the default, C-b

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

Split windows using o and u

# More friendly split pane
bind-key o split-window -h
bind-key u split-window -v

bind-key j select-pane -D
bind-key k select-pane -U
bind-key l select-pane -R

Status Bar

modified from https://github.com/sei40kr/tmux-airline-dracula/blob/master/airline-dracula.tmux

get colours using:

for i in {0..255}; do printf "\x1b[38;5;${i}mcolour%-5i\x1b[0m" $i ; if ! (( ($i + 1 ) % 8 )); then echo ; fi ; done

Set up the colors

black='colour0'
white='colour255'
gray='colour7'
dark_gray='colour8'
yellow='colour215'
light_purple='colour141'
dark_purple='colour61'
# black='colour233'
# white='colour255'
# gray='colour246'
# dark_gray='colour234'
# cyan='colour159'
# light_blue='colour75'
# dark_blue='colour31'
blue=color4

Example of powerline separators (not using these at the moment)

left_sep=''
right_sep=''
right_alt_sep=''
