Let's start by discussing what we do after editing a file. How do we check what changes have been made?

Student 1
Student 1

Do we use the `git status` command?

Teacher
Teacher

Exactly! `git status` is a key command that shows which files have been modified. Can anyone tell me why checking the status is important?

Student 2
Student 2

It helps us see what changes are staged and what still needs to be added!

Teacher
Teacher

Correct! Remember, we can use `git status` to ensure we are aware of every change before we commit.

Now that we've checked our changes, what's the next step?

Student 3
Student 3

We need to add the changes, right?

Teacher
Teacher

Yes! We use `git add <file>` to stage our modifications. Why do we stage changes instead of committing all files immediately?

Student 4

It lets us choose which changes to include in our next commit.

Teacher

Exactly! Staging gives us control and helps us create clearer commit histories.

Moving on, once changes are staged, we commit them. What command do we use?

Student 1
Student 1

We use `git commit -m <message>`!

Teacher
Teacher

Right! Backing up your work with descriptive messages is crucial because they serve as logs for our project. Can anyone give me an example of a good commit message?

Student 2

Updating homepage with new header.

Teacher

Perfect! Always think of your commit messages as a journal entry, capturing the essence of what you changed.

Committing in Git can be thought of as taking a snapshot of your project. Why is this analogy useful?

Student 3
Student 3

It shows that we can revert back to this state any time!

Teacher
Teacher

Exactly! If something goes wrong later, we can always return to a previous snapshot. How often should we commit?

Student 4
Student 4

As often as needed, especially after making significant changes.

Teacher
Teacher

Absolutely! Frequent commits lead to a clearer project history and easier collaboration. Let's remember 'Commit Often, Commit Early!'

Introduction & Overview

Read a summary of the section's main ideas. Choose from Basic, Medium, or Detailed.

Quick Overview

This section covers how to make and save changes to files in a Git repository.

Standard

In this section, you'll learn how to edit files, check for changes, stage those changes, and commit them to save your work in Git, creating snapshots of your project throughout its development.

Detailed

In the 'Making and Saving More Changes' section, we explore how to edit files within a Git repository and track those changes effectively. The process involves checking the status of your files to see any modifications, staging the changes you want to include in your next commit, and then committing those changes with a descriptive message. Each commit acts as a snapshot of your project at that moment, making it easier to track progress and revert to previous versions if necessary. By following these steps, you ensure that your project history is clear and that collaborating with others becomes seamless, as everyone can see the evolution of the code. This section reinforces the workflow of making changes and documenting them correctly within Git, emphasizing regular commits as a best practice.

Editing the File

Edit index.html:

Welcome!

Detailed Explanation

In this step, you will update your HTML file called 'index.html'. The content inside the file will change to include a simple HTML structure with a welcome message in an 'h1' heading tag. This is a straightforward edit to make your webpage more inviting.

Examples & Analogies

Think of this like updating a greeting sign at the entrance of a shop. You are changing what visitors see when they first arrive, making it more appealing or informative.

Check What's Changed

Step 1: Check what's changed
git status

Detailed Explanation

After editing your file, you need to see what changes have been made compared to the last saved version. Running the command 'git status' will show you the current status of your repository and indicate which files are modified, staged, or untracked.

Examples & Analogies

Imagine you're inspecting your garden after returning from a vacation. You check what has grown or changed since you were last there. Similarly, 'git status' helps you see what has been altered in your project.

Staging the Changes

Step 2: Add changes
git add index.html

Detailed Explanation

The next step is to stage your changes. By using 'git add index.html', you mark the file 'index.html' to be included in the next commit. This is essentially telling Git, 'I’m ready to save this update.'

Examples & Analogies

This is like setting a task aside to complete later. You pull it out of your daily to-do list and put it in a separate folder labeled 'To Submit', indicating it’s ready for review.

Committing the Changes

Step 3: Commit again
git commit -m "Updated homepage with h1"

Detailed Explanation

After staging the changes, the final step is to commit them. By executing 'git commit -m "Updated homepage with h1"', you are saving the staged changes to the Git history with a descriptive message. This allows you and others to know what this particular change entails.

Examples & Analogies

Think of this as filing a report after completing a project. Your commit message acts like a headline that summarizes the important aspects of your work, making it easier for you to refer back to it in the future.

Understanding Commits as Snapshots

Unlock Audio Book

Each commit is a snapshot of your project.

Detailed Explanation

Every time you make a commit, it captures the entire state of your project at that moment, much like taking a photo. Each commit serves as a point in time that you can return to, allowing you to track your progress and revert to previous versions if necessary.

Examples & Analogies

Picture taking snapshots at a family event. Each photo preserves a unique moment in time that you can look back on. In the same way, each commit functions as a historical snapshot of your project's evolution.

Definitions & Key Concepts

Learn essential terms and foundational ideas that form the basis of the topic.

Key Concepts

  • Checking for Changes: Using git status to identify modified files.

  • Staging Changes: Using git add to prepare files for commit.

  • Committing Changes: Using git commit -m <message> to save snapshots of your project.

  • Snapshot Concept: Each commit acts as a snapshot of your project state.

Examples & Real-Life Applications

See how the concepts apply in real-world scenarios to understand their practical implications.

Examples

  • After editing 'index.html' to add a header, run git status to see that it’s modified.

  • Use git add index.html to stage the changed file before committing it.

Memory Aids

Use mnemonics, acronyms, or visual cues to help remember key information more easily.

🎵 Rhymes Time

  • If you’ve made a change, don't let it be lost, check the status, add, then commit, that’s the cost!

📖 Fascinating Stories

  • Imagine building a house: every time you complete a step, you take a photo (commit) and jot down what you did (commit message) to remember the process later.

🧠 Other Memory Gems

  • Remember 'SAC' for saving changes: S = Status, A = Add, C = Commit.

🎯 Super Acronyms

USE COMMIT

  • Use `git status`
  • Add changes
  • Commit with a message.
