Gitlet

Written in Java

A version-control system that mimics some of the basic features of the popular system Git. This project was created for UC Berkeley’s CS 61B: Data Structures in Spring 2020.

Source code for this project can be provided upon request.

Features

Some functionality of Gitlet include:

  • Save contents of files in commits
  • Restore a version of one or more files or entire commits
  • View history of backups
  • Maintain related sequences of commits in branches
  • Merge changes made in one branch into another
  • Simplified implementation of Git’s remote features
  • Wrote unit tests and integration tests to ensure quality of the application

Preview

Note that all of the commands are prefaced with java gitlet.Main.

  • Initialize a Gitlet repository using the init command. This will create a .gitlet folder, which contains files such as serialized commits and objects.
  • Check the status of files and branches in your repository using the status command.
  • Create a new branch with a specified name using branch [branch name].

Init, Status, Branch

  • Stage files for addition using add [file name].
  • Create a new commit of files so that they can be restored at a later time using commit [message].
  • View a log of the commit history in the current branch using log.

Add, Commit, Log

  • Remove a file from the commit using rm [file name].
  • Checkout a different branch using checkout [branch name] to make [branch name] the active branch.
  • Merge two branches using merge [branch name].

Remove, Checkout, Merge

  • Reset to a different commit using reset [commit id]
  • Remove branch with a given name using rm-branch [branch name]
