running multiple commands in multiple terminal tabs

[William Hertling]

I'm trying to resurrect an old project, which is a cluster of ruby scripts and rails projects from about two years ago. The project is composed of 3 different rails servers, two different sets of resque workers, a redis database, and a couple of schedulers. In those dark ages, we had a ruby script that would use the rb-appscript gem to interface with Apple Terminal and run all of the dependencies in different terminal tabs.

As we try to bring this project back to life, the main that seems to have broken is in the way the ancient rb-appscript gem tries to interact with current OSX. rb-appscript hasn't been updated in years and years.

Is there any replacement for rb-appscript? Is there any better, newer way of doing this?

Hi William,

This sounds like it might be a nice use-case for Docker. Or if you want
something that can automatically manage tabs, maybe tmux? I have bash
functions like this for all my projects:

function foo-code {

env_name=code
long_name=foobarbaz
short_name=foo
tmux_session=${short_name}-${env_name}

if tmux list-sessions | grep ${tmux_session}; then
tmux attach-session -t ${tmux_session}

else
cd ~/src/${long_name}/site/app/models && \
tmux new-session -d -s ${tmux_session} && \
tmux rename-window -t ${tmux_session}:1 models

cd ~/src/${long_name}/site/app/controllers && \
tmux new-window -t ${tmux_session}:2 -n controllers

cd ~/src/${long_name}/site/app/views && \
tmux new-window -t ${tmux_session}:3 -n views

cd ~/src/${long_name}/site/app/assets/stylesheets && \
tmux new-window -t ${tmux_session}:4 -n css

cd ~/src/${long_name}/site/app/assets/javascripts && \
tmux new-window -t ${tmux_session}:5 -n js

tmux select-window -t ${tmux_session}:1 && \
tmux -2 attach-session -t ${tmux_session}
fi
}

In your case you can skip the cd'ing, and you can pass extra arguments
to those new-window commands to run shell commands in each one.

Foreman is a quick and easy way to run multiple ruby scripts/services simultaneously, though they'll all be in the same terminal session.

Along the lines of Paul's suggestion, I came across this this morning, which I haven't yet tried, but I'll be a very happy camper if it works well: https://github.com/tmux-plugins/tmux-resurrect

I use https://github.com/tony/tmuxp to open multiple panes with each executing a different script.

I really like https://github.com/tmuxinator/tmuxinator for my projects with a lot of service dependencies.

As Jason mentioned, I'd check out Foreman. It's quick and easy to setup.

One reason I opted for tmuxinator over Fireman is that (at least in the past) if you wanted to restart one service with Foreman you had to restart all of them. Maybe there's a way to do that now with more fidelity.

I don't see a way to restart one service with Foreman. Typically if I find that I need to continually restart a service in my development, I'll comment that service out of my Procfile and run that service in a separate terminal window where I can restart as needed while running the remaining with foreman. 

[William Hertling]

Thanks all the for the recommendations! I'm going to give tmuxinator a try.
