Git/Submodules

Notes

I use submodules to organize groups of related repositories and make checking out lots of repos a breeze.

Adding Submodules to Repository

Check out the repository that you want to put submodules into:

git clone https://charlesreid1.com:3000/rpi/pi-master.git
cd pi-master

Now add submodules:

git submodule add <git-repo-url>

Here's the script:

#!/bin/bash

git submodule add https://charlesreid1.com:3000/rpi/pi-opencv.git
git submodule add https://charlesreid1.com:3000/rpi/pi-startup-services.git
git submodule add https://charlesreid1.com:3000/rpi/pi-transmission.git
git submodule add https://charlesreid1.com:3000/rpi/pi-stunnel.git
git submodule add https://charlesreid1.com:3000/rpi/pi-setup.git
git submodule add https://charlesreid1.com:3000/rpi/pi-process-wifi-data.git
git submodule add https://charlesreid1.com:3000/rpi/pi-join-wifi.git
git submodule add https://charlesreid1.com:3000/rpi/pi-aircrack-batch.git

This will add a .gitmodules file automatically.

When you're done, make the commit:

git commit -am 'adding submodules'

Checking Out Repository with Submodules

Start by checking out the repository with the submodules:

git clone https://charlesreid1.com:3000/rpi/pi-master.git

Initialize the repository submodules:

git submodule init

or, do it all at once:

git clone --recurse-submodules https://charlesreid1.com:3000/rpi/pi-master.git

Fetching Changes to Submodules

To pull changes for each of the submodules, run

git submodule update --remote
