If you are a developer or a team of developers, you would know how important it is to have a proper version control system in place. Git is one of the most widely used version control systems out there. But have you heard of "Gitlet"?
Gitlet is a version control system that is built on top of Git. It is a simplified version of Git, which means that it is easier to use, understand, and maintain. Gitlet was created by Stanford University student Calvin Zhang as part of his CS61B class project.
The main idea behind Gitlet was to build a version control system that is similar to Git, but with some added features and simplified code.

How Does Gitlet Work?

Gitlet works by creating a ".gitlet" directory in the root of your project directory. This directory contains all the necessary files that Gitlet uses to manage your project's version history. Whenever you make changes to your project files, Gitlet takes a snapshot of the current state of your project and stores it in the ".gitlet" directory. This snapshot is called a "commit".
Gitlet also has a "staging area", which is where you can add or remove files from the next commit. This allows you to only commit the changes that you want, instead of committing everything in the project directory.
Gitlet also has a feature called "branching", which allows you to work on multiple versions of your project simultaneously. This can be useful if you want to experiment with different features or ideas without affecting the main project.

Gitlet V/S Git

While Gitlet is built on top of Git, there are some key differences between the two version control systems. Here are a few of the main differences:

Gitlet Is Easier To Use

One of the main advantages of Gitlet is that it is easier to use than Git. Gitlet has a simpler command-line interface that is easier to understand and remember. This can be especially useful for developers who are new to version control systems and may be overwhelmed by Git's complex commands and options.

Gitlet Is Lightweight

Another advantage of Gitlet is that it is lightweight. Gitlet's code is much smaller than Git's codebase, which means that it is faster and easier to maintain. This can be especially useful for small projects or projects that don't require the full set of features that Git offers.

Gitlet Has A Simplified Codebase

Gitlet's codebase is also simpler than Git's codebase. This makes it easier to understand how Gitlet works and to modify its code if necessary. It also makes it easier to debug issues and fix bugs.

Git Has More Features

One of the main advantages of Git over Gitlet is that it has more features. Git has a wide range of commands and options that can be used to manage your project's version history. Git also has a large user community and a wealth of resources available online, which can be useful for developers who are looking for help or advice.

Getting Started With Gitlet

If you are interested in trying out Gitlet, you can download it from the official GitHub repository. Here's how you can get started with Gitlet:
  • Download the latest release of Gitlet from the official GitHub repository.
  • Extract the files to a directory of your choice.
  • Open a terminal or command prompt and navigate to the directory where you extracted .
  • Run the command java gitlet.Main init to initialize a new Gitlet repository in the current directory. This will create a new ".gitlet" directory in the current directory.
  • Add some files to your project directory and run the command java gitlet.Main add <filename> to add them to the staging area.
  • Once you have added all the files that you want to commit, run the command java gitlet.Main commit "<commit message>" to create a new commit.
  • You can use the command java gitlet.Main log to view the commit history of your project.
  • If you want to create a new branch, you can use the command java gitlet.Main branch <branch name>.
  • To switch to a different branch, you can use the command java gitlet.Main checkout <branch name>.
  • Finally, if you want to merge two branches, you can use the command java gitlet.Main merge <branch name>.

Unique Features Of Gitlet

While Gitlet is similar to Git in many ways, it also offers some unique features that set it apart. Here are a few of the main unique features of Gitlet:

Automatic Tracking Of File Renames

One of the main unique features of Gitlet is its automatic tracking of file renames. When you rename a file in your project directory, Git treats it as a new file and deletes the old file. This can be problematic if you want to track the history of the renamed file.
Gitlet, on the other hand, automatically detects file renames and tracks them as a rename operation. This means that you can see the history of the renamed file and its previous names.

Reset Command With Options

Gitlet's reset command offers some additional options that Git's reset command doesn't have. For example, you can use the -- hard option to reset your project directory to the state of a previous commit, discarding any changes that you have made since then.
You can also use the -- soft option to reset your project directory to the state of a previous commit, but keep the changes that you have made since then in the staging area. This can be useful if you want to re-commit the changes with a different commit message.

Debugging Commands

Gitlet also has some debugging commands that can be useful for diagnosing issues with your repository. For example, you can use the java gitlet.Main find <commit message> command to find the commit ID of a commit that has a specific commit message.
You can also use the java gitlet.Main status command to see the current state of your repository, including which files are staged for the next commit and which files have been modified since the last commit.

Viewing The Commit History In Gitlet

One of the most important features of any version control system is the ability to view the history of your project's changes. In Gitlet, you can view the commit history of your project using the java gitlet.Main log command.
When you run this command, Gitlet will display a list of all the commits that have been made to your project, starting with the most recent commit. Each commit will be displayed with its commit ID, the commit message, the date and time of the commit, and the author of the commit.
You can use this commit history to track the changes that have been made to your project over time and to see who made each change and when. You can also use the commit ID to check out a specific version of your project.
By default, the java gitlet.Main log command will display the commit history for the current branch. However, you can also view the commit history for a specific branch or for all branches using the --all option.

Switching Between Branches In Gitlet

One of the key features of any version control system is the ability to work on multiple versions of your project simultaneously. In Gitlet, you can do this using branches.
A branch is a separate version of your project that can be modified independently of the main project. Each branch has its own commit history and can be merged into the main project when ready.
To switch between branches in Gitlet, you can use the java gitlet.Main checkout <branch name> command. When you run this command, Gitlet will switch your project directory to the specified branch and update the files in your project directory to match the state of the branch.
It's important to note that any changes that you have made in your current branch that are not in the new branch will be discarded. If you want to keep these changes, you should commit them before switching branches.
You can also create a new branch in Gitlet using the java gitlet.Main branch <branch name> command. This will create a new branch at the current commit, allowing you to work on a new version of your project independently of the main project.
