Git magic - commit amend

Published on

Like I said already about hard reset, it's a nasty way to alter a commit. Then what is the better way? 

That's exactly what I have written in this post about how we could use amend and what does it do.

/**

What is amend in git commit?

In git commit, when you add the attribute --amend like git commit --amend, it lets you edit the most recent commit. 

git commit --amend

So, when you give this command, it opens VIM editor with your latest commit message. Here you can edit your commit message and update it & push.

Is that all?

The answer is no. If you have changes in any of the files and you want to add them to your most recent commit, you can stage those files to commit. Then when you execute the above command, the most recent commit message is shown in the VIM editor or whatever default editor you have along with the newly staged files.

Therefore when you save the commit message from VIM editor, it updates the file changes as well to your most recent commit.

Therefore to sum up, with git commit --amend you can,
  • Update the latest commit message
  • Add / Remove / Modify files from / to the latest commit
I guess that tip helps whenever you have a case where the most recent commit needs to be updated.

Git worktree - guide to flexible folder structure

Published on
As always, let's start with a story why I have written this one down. I have been using git for almost 5 years now and in one of my work places I had to work on the same project but different features in parallel.  Switching between branches back and forth was a costly operation given that I didn't discover commit amend until recently. Even though I'd have discovered commit amend, I'd still have did this. Still did what? I can sense that question deep from your throats. So, whenever I am in a situation to work on multiple features or a feature and a bug fix, I'd have two clones of my repo each with different branches, Whenever a feature is merged or the fixes are merged, I'll delete the clone in my machine and branch in my origin (Gitlab / Github etc.,) Recently when I started writing these git articles, my manager suggested me to learn about Git Worktree and it'll be useful. And when I got free and good understanding of git commit, rebase and stuff, I decid...

npm-link | What NPM won't tell you!

Hello readers. So back with another easy yet unexplored feature of npm/yarn packages. We as frontend developers / SDK developers, have to deal with more than one repositories where we actually code contribute. Most SDK developers would know this already or they use the not-so-well documented 'npm link' command . /**  *  @disclaimer  * Please read this post fully before executing any command.

Building AI Apps - The basics you need to know

Published on
So you want to build an AI assistant? Maybe for customer support, maybe to search through documents, or maybe just to automate some boring stuff at work. You keep hearing words like "prompting", "RAG", "fine-tuning" thrown around in meetings. But what do they actually mean and which one do you need? Let me walk you through building a customer support AI assistant and show you how each of these concepts fits in. /**  * @disclaimer  * This is an educational post based on my learnings.  * I'll share actual experiments in future posts.  * Your use case might be different, so take what applies to you. */ What even is an LLM? Before we jump into the techniques, let's start with the basics. What is an LLM? Think of a Large Language Model (LLM) as someone who has read most of the internet but has zero memory of your conversation once it ends. Models like GPT-4, Claude, or Llama have been trained on massive amounts of text data. They know a lot...
