A boilerplate tmux shell script I use for including in my projects to aid development. This one isn't specific to any tech other than it uses guard. I might include others that are for node/ruby or even go as far as to specific frameworks express/sinatra/rails.

start_development

#!/bin/sh

BASE=`pwd`
PROJECT='xxxxx'

tmux start-server
 
# new-session creates first window named 'console'
tmux new-session -d -s $PROJECT -n console 
 
# split window 'h'orizontally (into two vertical panes)
tmux split-window -t $PROJECT:console -h
 
# select the left-most pane
tmux last-pane
 
# split this pane 'v'ertically (into two horizontal panes)
tmux split-window -t $PROJECT:console -v
 
# create a second window for 'logs'
tmux new-window -t $PROJECT:2 -n logs
 
# start a vim editor in the left-most vertical pane
tmux send-keys -t $PROJECT:console.2 "cd $BASE;" C-m
 
# widen the vim editor pane by 20 cells
tmux resize-pane -L -t $PROJECT:console.2 20
 
# run guard -c clears shell after each change
tmux send-keys -t $PROJECT:console.0 "cd $BASE; guard -c" C-m
 
# start rails server
tmux send-keys -t $PROJECT:console.1 "cd $BASE;" C-m
 
# start logging
tmux send-keys -t $PROJECT:logs "cd $BASE;" C-m
 
# select the vim pane in the rails window
tmux select-window -t $PROJECT:console
tmux select-pane -t $PROJECT:console.2

# new-session creates a third window named 'dev'
tmux new-window -t $PROJECT:3 -n dev 
tmux split-window -t $PROJECT:dev -h
tmux send-keys -t $PROJECT:dev.0 "cd $BASE; vim" C-m
tmux send-keys -t $PROJECT:dev.1 "cd $BASE; vim" C-m
 
# make the tmux session active
tmux attach-session -d -t $PROJECT
