# GENERAL

# Use a larger window history, in lines.
set-option -g history-limit 10000

# Display messages for three seconds.
set-option -g display-time 3000


# TERMINAL

# Disable alternative screen feature. This way e.g. Vim's window content stays
# visible after quitting Vim. This is quite useful to copy data (needs tmux
# 1.5 to work (almost) completely).
set-window-option -g alternate-screen off

# Set title for outer terminal.
set-option -g set-titles on

# Don't rename windows to the currently running program, my zshrc does this
# for me (with some additional features).
set-window-option -g automatic-rename off


# STATUS LINE

# White text.
set-option -g status-fg white
# Bright blue background color (colour12).
set-option -g status-bg colour12

# Nothing left of window list.
set-option -g status-left ""
# Current load average and hostname on the right.
set-option -g status-right "#(uptime | sed 's/^.*load averages*: //; s/,//g') \
                            #H"

# Format for windows in the window list in the status line. #I window index,
# #W window number, #F window flags.
set-window-option -g window-status-format         "#I #W#F"
set-window-option -g window-status-current-format "#I #W#F"

# Update status line commands (#(..)) only every minute.
set-option -g status-interval 60


# BINDINGS

# Use Vi(m) key bindings.
set-option        -g status-keys vi
set-window-option -g mode-keys vi

# Use Ctrl-A as escape binding, like in GNU screen.
set-option -g prefix C-a
# Ctrl-A a sends Ctrl-A to the process, like in GNU screen.
bind-key a send-prefix
unbind-key C-b

# GNU screen like bindings (with C-x).
bind-key C-c new-window
bind-key C-a last-window
bind-key C-n next-window
bind-key C-p previous-window

# Arrow-key replacements for tmux's prompt.
bind-key -t vi-edit C-n history-down
bind-key -t vi-edit C-p history-up

# Display date/time, similar to GNU screen's ^a ^t. Tmux's default ^a t just
# displays the current time, but I often want to know the current date.
bind-key C-t display-message

# Run urlview on the current screen content. Very useful to follow links.
# Thanks to Arch wiki (https://wiki.archlinux.org/index.php/Tmux) for the
# basic idea.
