Git magic - commit amend

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.

WebRTC - What the heck?

Over the past few weeks, I happened to work on stuff that enabled me to understand what WebRTC is and how useful it is.  The full form? Web R eal- T ime C ommunication The history It's first release was by 2011. If you want to know more, well, please read the wikipedia . WebRTC  has been a boon to web developers who want to build streaming applications or video calling applications. As you move downward, you'll just may be understand how WebRTC works but nothing technicals.  The story Let's begin with a short story. Long long ago, so long ago, nobody knew how long ago, there lived two shop keeper farmers John & Finch. It was that old point in time when barter system was a thing and money wasn't invented.  These shopkeepers lived in different cities across a river and the cities were connected by a rock solid bridge. Like how the golden gate connects the San Francisco city and the Marin County. Finch is a very private person and takes hard time to trust people. John

TDD - How to go about it? - A quick start example

So, it's only recently I've been doing TDD. I have written unit tests before but those were all tests after writing the actual code. Confusing statement right? /**  * @disclaimer  * I'm just preaching what I practice and some parts of it could be wrong.  * Please feel free to leave comments if am wrong  * And I would be happy to stand corrected */ What is TDD? TDD, expanded as Test Driven Development could have this statement as one of the definitions. "TDD is nothing but the art of writing down the business use case one by one and write code based on it paralelly" It would feel like why do I need to write test for that? We could do the same with pen & paper and write codes. But then, you again circle back to write tests for the same. So why not do it this way?  Therefore, let's start with an example, Write a method that accepts two positive numbers as input and returns their sum Let's try and do a mock TDD for the above problem.  Case 1 - Function add

Git worktree - guide to flexible folder structure

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
