Git Submodules - Basic Explanation

Why submodules?

In Git you can add a submodule to a repository. This is basically a sub-repository embedded in your main repository. This can be very useful. A couple of usecases of submodules:

Separate big codebases into multiple repositories.

	#!/usr/bin/env python3
	# inspire by https://www.slsmk.com/getting-the-size-of-an-s3-bucket-using-boto3-for-aws/
	import boto3
	import datetime

	def main():
	# Get all regions
	ec2 = boto3.setup_default_session(region_name='us-east-1')
	ec2 = boto3.client('ec2')
	desc_regions = ec2.describe_regions()

	import boto3
	from datetime import date
	from datetime import datetime
	today = date.today()
	today = datetime.combine(today, datetime.min.time())

	client = boto3.client('s3')

	# Get all buckets
	response = client.list_buckets()

	// Javascript helper functions for parsing and displaying UUIDs in the MongoDB shell.
	// This is a temporary solution until SERVER-3153 is implemented.
	// To create BinData values corresponding to the various driver encodings use:
	// var s = "{00112233-4455-6677-8899-aabbccddeeff}";
	// var uuid = UUID(s); // new Standard encoding
	// var juuid = JUUID(s); // JavaLegacy encoding
	// var csuuid = CSUUID(s); // CSharpLegacy encoding
	// var pyuuid = PYUUID(s); // PythonLegacy encoding
	// To convert the various BinData values back to human readable UUIDs use:
	// uuid.toUUID() => 'UUID("00112233-4455-6677-8899-aabbccddeeff")'

	## I just ran into this after initializing a Visual Studio project _before_ adding a .gitignore file (like an idiot).
	## I felt real dumb commiting a bunch of files I didn't need to, so the commands below should do the trick. The first two commands
	## came from the second answer on this post: http://stackoverflow.com/questions/7527982/applying-gitignore-to-committed-files

	# See the unwanted files:
	git ls-files -ci --exclude-standard

	# Remove the unwanted files:
	git ls-files -ci --exclude-standard -z \| xargs -0 git rm --cached

	var express = require('express')

	var app = express()

	order by starttime desc;

	-- Gets all queries that have been aborted for a given date range
	select starttime, endtime, trim(querytxt) as query, aborted

	git branch -m old_branch new_branch # Rename branch locally
