Tmux Start Session Maximized With Three Panes

So I got tired of starting up a dedicated tmux session to manage all the work related to my writing sessions. Over the past few months, I’ve boiled it down to three.
And it still irks me that I have to …

Launch Terminal
Launch Tmux
Split it into three windows err … panes.
Go to the top left pane and launch Hugo server
Switch to the right pane and then launch Emacs with whatever new post I want to write today.

So of course, a Rube Goldberg-esque, tiny bash-pipey monster took form. It now resides, chained to an alias, hssx¹ in my .bash_aliases file

1

alias hssx='cd /path/to/my/hugo/folder && \
xdotool windowsize $(xdotool getactivewindow) 100% 100% && \
tmux new-session \; split-window -h \; select-pane -l \; split-window -v \; select-pane -U \; send-keys "hugo serve" C-m \; select-pane -R'

The first line switches to my hugo folder
The second calls xdotool and maximises the terminal window
And the last line is a series of instructions to the tmux command. I’ve split it below for readability.

tmux new-session \; #Tmux start a new session
split-window -h \; # Split the window into two vertical panes
select-pane -l \; # Switch to the left pane
split-window -v \; # Split that into two horizontal panes
select-pane -U \; # Select the upper pane
send-keys "hugo serve" C-m \; # Type in `hugo serve` followed by Enter
select-pane -R # Select the right pane

And boom!
