A Gentle Introduction to Git Worktree

Git worktree has become a major part of how I use Git over the past year. Anytime I mention it somewhere however, I get reactions from people who have never heard about the feature. Others have heard about it, but don't know how exactly it works or why it's beneficial. That's why I decided to write a short tutorial/introduction on this awesome feature that is baked right into the very git you are already using. I hope this can help people discover worktrees and be a gentle introduction on how to get started using them.

What is Git worktree

Git worktree facilitates working with multiple branches. In a normal Git workflow, you can only ever have one branch checked out at a single time.

This is not working complete code.

This is strictly a v0.2, scrapy, proof of concept version of a personal AI Assistant working end to end in just ~726 LOC.

This is the second iteration showcasing the two-way prompt aka multi-step human in the loop. The initial, v0, assistant version is here.

It's only a frame of reference for you to consume the core ideas of how to build a POC of a personal AI Assistant.

	# Let's say you were stupid and used the postgres account for something you
	# shouldn't have, so you have a database owned by postgres, with all objects
	# inside owned by postgres. You regain sanity and want to transfer the
	# ownership to an account that isn't a database superuser.
	#
	# In most cases, reassigning ownership is as simple as using
	# REASSIGNED OWNED. However, that does not work if you are using the
	# postgres account, so you have to alter the ownership manually.
	#
	# First, make sure you connect to the database using the postgres account.

	var seconds = parseInt(seconds, 10)
	var hours = Math.floor(seconds / 3600)
	var minutes = Math.floor((seconds - (hours * 3600)) / 60)
	var seconds = seconds - (hours * 3600) - (minutes * 60)
	if ( !!hours ) {
	if ( !!minutes ) {
	return `${hours}h ${minutes}m ${seconds}s`
	} else {
	return `${hours}h ${seconds}s`
