How to create a layout and run commands in at tmux launch? - tmux

Question

I am trying to write a script I can run/source so tmux set a specific layout and run commands. I have some results.
Here is what I've written so far:
selectp -t 1
splitw -v -p 15
splitw -h -p 50
selectp -t 1
send-keys 'cd ~/code/octoly' Enter
send-keys 'vim .' Enter
selectp -t 2
send-keys 'cd ~/code/octoly' Enter
send-keys 'drails c' Enter
new-window -d -n server -c ~/code/octoly
selectw -t 2
send-keys 'fd' Enter
splitw -h -p 50
send-keys 'cd ~/code/octoly' Enter
send-keys 'drails s' Enter
selectp -t 1
splitw -v -p 50
send-keys 'cd ~/code/octoly' Enter
send-keys 'be guard' Enter
What works more or less is the creation of the second window and the panes. Though the panes does not give me what I want. They are all created in the first window, none are created in the second.
Here is what I run to start tmux:
tmux new 'tmux move-window -t 99 \; source-file ~/.tmux/session_octoly'
Furthermore, where I'm really lost is that if I run each command by hand one by one, it gives me what I want.
What am I missing here?

First of all, you're using the -d flag in new-window that does not make the new window the current window:
If -d is given, the session does not make the new window the current window.
However I would probably spin up tmux in a different way, using tmux -f flag to use an ad-hoc config file that does what you want.
Please check the commands before running it in you're environment.
# File: ~/.tmux/octoly.conf
# Load default .tmux.conf
source-file ~/.tmux.conf
# setup octoly session
new-session -s octoly -n editor -d -c ~/code/octoly
send-keys 'vim .' Enter
split-window -v -p 15 -c ~/code/octoly
send-keys 'drails c' Enter
split-window -h -p 50 -c ~/code/octoly
# Select vim pane
select-pane -t 1
# create second window
new-window -n server -c ~/code/octoly
send-keys 'fd' Enter
split-window -h -p 50 -c ~/code/octoly
send-keys 'drails s' Enter
select-pane -t 1
split-window -v -p 50 -c ~/code/octoly
send-keys 'be guard' Enter
# Optional step, reselect window 1 (the one with vim)
select-window -t editor
Then you need to launch tmux using:
tmux -f ~/.tmux/octoly.conf attach
Another alternative would be to build a bash script sending the same commands.
Note: I've used the -c flag to specify the start directory instead of running every time a cd command. Given that every command is run in the same folder you can take them out in the split-window commands.
