# Tmux Configurations

#------------------------------------------------------------------------------
# Configuration Notes
#------------------------------------------------------------------------------
#
# Tmux has shortened versions of some commands, the following are used:
# set  = set-option
# setw = set-window-option
# bind = bind-key
# run  = run-shell
#

set-environment -g TMUX_PLUGIN_MANAGER_PATH "$XDG_DATA_HOME/tmux/plugins"

#------------------------------------------------------------------------------
# Set helper script path
#------------------------------------------------------------------------------
#
# This is where custom helper scripts need to be located for tmux
# to utilize them.
#

script_path="$HOME/.config/tmux/scripts"

#------------------------------------------------------------------------------
# Open windows and panes in current directory
#------------------------------------------------------------------------------
#
# By default Tmux opens new windows and panes in the user home directory, I
# would prefer they open in the directory I am currently in since I am usually
# working on a project and just need a new terminal window.
#

bind c new-window -c "#{pane_current_path}"
bind '"' split-window -v -c "#{pane_current_path}"
bind % split-window -h -c "#{pane_current_path}"

#------------------------------------------------------------------------------
# Turn on mouse reporting for native scrolling
#------------------------------------------------------------------------------
#
# This allows tmux to scroll contents using the mouse scroll wheel.
#

set -g mouse on


#------------------------------------------------------------------------------
# Speed up refresh rate
#------------------------------------------------------------------------------
#
# Using Gitmux is nicer with a faster response time, this speeds up how
# quickly the Tmux status bar will refresh itself with new information.
#

set -g status-interval 1 

#------------------------------------------------------------------------------
# Set Tmux 256 Colors
#------------------------------------------------------------------------------
#
# More colors!
#

set -g  default-terminal 'tmux-256color'
set -as terminal-overrides ',xterm*:Tc:sitm=\E[3m'

#------------------------------------------------------------------------------
# Set Focus Events On
#------------------------------------------------------------------------------
#
# Neovim :checkhealth recommends setting focus-events to on. What does it do?
#

set -g focus-events on

#------------------------------------------------------------------------------
# Order sessions by name
#------------------------------------------------------------------------------
#
# <prefix>s provides a list of open sessions, I find it easier to scan them
# if they are ordered alphabetically ascending by name.
#

bind s choose-tree -ZsNO name

#------------------------------------------------------------------------------
# Message Style
#-----------------------------------------------------------------------------
#
# <prefix>:
#

set -g message-style 	              "bg=default, fg=#000000,bold"
set -g message-command-style        "bg=default, fg=#000000,bold"

#------------------------------------------------------------------------------
# Set indexes to 1 instead of 0
#------------------------------------------------------------------------------
#
# A lot of programming languages are zero indexed. But I'm not programming
# when using Tmux. I am using an interface. I want lists to start from 1,
# which coincidentally also matches the leftmost number key on my keyboard.
#
# Below, "panes" and "windows" are configured to start at 1.
# 
# It is unfortunately not possible to start the session list from 1 yet.
#

set  -g mode-style "bg=#3B82F6,fg=#FDFDFF"
set  -g renumber-windows on  
set  -g base-index 1         
setw -g pane-base-index 1    

#------------------------------------------------------------------------------
# Status Bar
#------------------------------------------------------------------------------
#
# I prefer the Tmux Status Bar at the top because it clashes with Neovim's
# Status Bar and Command Lines. I also prefer to think of Tmux's Status Bar
# as a macOS style "Menu Bar for the command line".
#

set -g status-position top

#------------------------------------------------------------------------------
# Status Bar Border
#------------------------------------------------------------------------------
#
# Move the status bar to the top and format it as an underline below the
# status bar. Set the pane borders to a color that blends with Neovim's
# Vertical and Horizontal Splits. 
#

setw -g pane-border-status top
setw -g pane-border-format '─'
set  -g pane-border-style 	        "bg=default, fg=#A3A6AE"
set  -g pane-active-border-style    "bg=default, fg=#A3A6AE"

#------------------------------------------------------------------------------
# Popup
#------------------------------------------------------------------------------
#
# Settings for the Tmux Popup function
#

set -g popup-border-lines "double"
set -g popup-border-style fg=black
bind-key p display-popup -T ' Shell ' -d "#{pane_current_path}"
