# ~/.tmux.conf
# Note: Keybindings in here with "C-" such as "C-q" indicate that you should
# press "Control" along with the second character (that is Ctrl-q in the
# example)

# Tmux will let you multiplex your terminal - multiple windows and panes in
# a single SSH session.  It will also persist when your network connection
# to a PCDS host goes down.
#
# To start tmux:
#   $ tmux
# To reattach to an existing session:
#   $ tmux attach
# Multiple sessions are possible.
#   -> To list running sessions while in tmux, type C-q s
#   -> Start a new session with just "tmux"

# To interact with tmux, use C-q
set -g prefix C-q

# Split windows vertically with C-q v (or C-q c-v)
bind v split-window -h
bind C-v split-window -h
# Split windows horizontally with C-q b (or C-q c-b)
bind b split-window -v
bind C-b split-window -v
# Go between windows with C-q n (next) or C-q p (previous)
bind p previous-window
bind n next-window

# Vim-like pane switching.
# Pane above: C-q k
bind -r k select-pane -U
bind -r C-k select-pane -U
# Pane below: C-q j
bind -r j select-pane -D
bind -r C-j select-pane -D
# Pane left: C-q h
bind -r h select-pane -L
bind -r C-h select-pane -L
# Pane right: C-q l
bind -r l select-pane -R
bind -r C-l select-pane -R

# For better interaction with vim inside of panes, consider using something
# like the following:
# This is based on vim-tmux-navigator, and you may need a vim plugin for it
# to work fully.
#
#   is_vim='echo "#{pane_current_command}" | grep -iqE "(^|\/)g?(view|n?vim?)(diff)?$"'
#   #   C-h - select the pane left
#   bind -n C-h if-shell "$is_vim" "send-keys C-h" "select-pane -L"
#   #   C-j - select the pane down
#   bind -n C-j if-shell "$is_vim" "send-keys C-j" "select-pane -D"
#   #   C-k - select the pane up
#   bind -n C-k if-shell "$is_vim" "send-keys C-k" "select-pane -U"
#   #   C-l - select the pane right
#   bind -n C-l if-shell "$is_vim" "send-keys C-l" "select-pane -R"
#   bind -n C-\ if-shell "$is_vim" "send-keys C-\\" "select-pane -l"

# Remap arrow keys (normally pane switch) to be resize,
# which will now be double-mapped with ctrl+arrow
bind -r Up resize-pane -U
bind -r Down resize-pane -D
bind -r Left resize-pane -L
bind -r Right resize-pane -R


# Enable mouse control (tmux > 1.8 will need some changes here)
set-option -g mode-mouse on
set-option -g mouse-resize-pane on
set-option -g mouse-select-pane on
set-option -g mouse-select-window on

# Later tmux versions: set -g mouse on
