#Source Code Management with Git

[redactedconcepts]

Source code management

What is source code management?

It allows a developer to organize code iterations chronologically, and version it for an application. The most powerful features of source code management systems are in how they allow teams of very diverse sizes to work together on the same application simultaneously.

Some terms that are common to all of them:

A project will be called repository, it’s representing the index/the filesystem root of your project.

Developers might create branches of the codebase, that they will iterate on separately to other developers. For instance, a branch can be meant to be used for a given feature, or a given bug fix. One can create however many branches they need.

Once a branch is ready for it (it’s been tested, peer-reviewed, etc.), it can be merged back to the main branch. The main branch may be called differently: in Git it’s called master , in SVN it’s called trunk.

While coding on their branch, developers are meant to work in small, atomic iterations, called commits. All commits have a commit message describing in one sentence what’s in there.

All commits together are called the history , and it’s a big deal to write meaningful commits and commit messages in order to keep the project’s history clean at a glance, to understand what has been going on and who did what.

Some people might be modifying the same pieces on the codebase on different branches, and this could create conflicts when one merges those branches together. Some of those conflicts can obviously only be fixed by a human, and each system has a different way to manage merge conflicts.

Which systems exist?

I’ll put each specific wording between quotes. The same words may be used for differing notions across the various products.

SourceSafe was an early source code management system from Microsoft, which didn’t handle branches, merges, or conflicts. You could “check out” a file, which meant no one else was allowed to “check it out” and modify it at the same time. When you were done with it, you could “check in” the file, making it editable again to the others. Not very suitable for large teams that may work on the same file, and longer iterations in a given file. SourceSafe is discontinued today.

CVS was among the first open-source source code management systems in the industry, and used to be wildly popular, but is barely seen anymore. It didn’t handle branches, but two people could modify the same file at the same time. People would “update” their whole directory to get everybody else’s work before starting, and “commit” their code to the server when they’re done. When they would “commit” a file that had been “committed” by someone else since last time they “updated”, the system was not able to merge, so it would consider it a conflict every time, that you would have to manually fix (even if the changes were not on the same lines, for instance).

SVN was built upon CVS to handle branches, so a lot of terminology is the same. At some point, it was the most used system, and it is still seen in the industry, even though people are walking away from it. When you’d create a branch, it would actually copy-paste the whole codebase into another directory in the code repository; then, you’d try to merge, and it would massively compare each file one by one. Merging algorithms were smarter than the CVS ones, but you still had conflicts on most merges, even those that shouldn’t necessarily require a human. When you’d create a “tag” (which is a set version of your code, like “1.2.0”), then the whole codebase would simply be massively copy-pasted into another directory too, but without the intention to merge it back later.

Git doesn’t copy-paste the whole codebase when branching and tagging, but stores each commit as a code iteration, in an organized structure that resembles a tree. This allows it to have a much smarter merging algorithm, and it almost never bothers you with conflicts, except for those that really need a human decision. As a result, the cost of branching/merging is very low, and people typically branch/merge a lot, therefore one should never directly work on the “master” branch, if they’re not the only developer on the project. Also: unlike its predecessors, Git allows to work and commit without needing to talk with a server, which allows to work on planes, for instance; and it also can work as a decentralized (peer-to-peer) system, although it’s very rarely done that way.

Mercurial is very similar to Git in its concepts (although the syntax of its command-line tool is often different). It is more rarely seen in the industry than Git, but is still very relevant. It is the one used by Facebook, for instance, for its main application.

The lowdown on Git

A particularity about Git, is that it’s designed to be useable without a central repository (you can pull code from your friend’s computer, and push you work back there, for instance), but not many people use it that way. There is usually a central Git server that the whole team pushes code to and pulls code from; however, that explains why it is often referred as a “decentralized” system.

So that you can work without a server, the commit operation is local, no one other than your computer knows you committed something. You can make several commits however you want, but when you want the server to know about it, you must push them there. You want to be pulling from the repository often if other people may be working on the same branch as you, because each pull performs a merge operation between the code you didn’t have, and the code you recently committed locally. Therefore, in order to let you push , Git will sometimes demand that you pull first, so that the merge can be done on your computer, and you take care of potential conflicts.

Sometimes, you may have modified 3 files, but there are only two that you wish to include in the commit you’re about the make. Therefore, Git has a notion of “ index”, in which you add your modified files so that they’re included in the next commit you register.

How to configure the remote servers your local repository is talking to? They’re called remotes , and you can configure however many you need. The main one is typically named origin (that’s the name that is setup by default when you clone a project from a remote location in the first place). You can also configure however many branches you need, and name them as you please, and the default one is usually called master.

Some UI tools for Git exist, but Git is able to do so many things, that they don’t represent the magnitude of cases for which you need Git. You really want to learn to use it with the command line. Here are some commands:

$ git clone url_of_your_remote_repository # Clone a repository from a remote repository $ git add file1 file2 # will add those two files to the index if they were modified $ git commit -m "Meaningful commit message" # will commit those two files (locally) $ git add . # will add all of the modified files to the index at once $ git commit -m "Other meaningful commit message" # will commit all of those files together $ git push origin master # send all commit to the remote server

Now, let’d do this again, but by on a branch:

$ git branch my_feature # Creating the branch $ git checkout my_feature # Changing the codebase so that we're on that branch now $ git checkout -b my_feature # This does the two previous operations in one ;) $ git add file1 file2 $ git commit -m "Meaningful commit message" # We didn't just commit this on the master branch like last time, but on the my_feature one $ git add . $ git commit -m "Other meaningful commit message" $ git push origin my_feature # Notice, we're not pushing master anymore, you just create a new remote branch

Next time you want to work on that branch, you should probably do this first:

$ git checkout my_feature # Just making sure you're currently on the right branch! $ git pull origin my_feature # Pulling what your coworkers have done so far.

And when you’re done with the whole feature and want to merge it to master:

$ git checkout master $ git merge my_feature

One other pretty neat thing: if you have a non-Git directory in your computer, and you want to turn it into a Git repository, it’s that easy:

$ git init # You're done! $ git remote add origin url_of_your_git_server # So that you can push your code somewhere.

When you’re in a Git repository, and want to know which files are modified but not in the index, and those that are modified and are in the index, you can run:

$ git status

Git provides many more abilities, such as rewriting pieces of the history of the project if you feel the commits were not meaningful enough, displaying the history in visually meaningful ways, …

For instance, you should run this right now, and see how a complex history can be viewed really nicely:

$ git clone [https://github.com/loverajoel/jstips.git](https://github.com/loverajoel/jstips.git) # You will need a GitHub account for this to work $ cd jstips # changing your directory into the one you just downloaded $ git log --graph --pretty=tformat:'%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%an %cr)%Creset' --abbrev-commit --date=relative

Cool, right?

What is the difference between Git and GitHub?

Git is everything we’ve covered so far: a source code management tool, that comes with a command-line tool for its users.

GitHub is one of many services that provide at the same time:

a Git repository server to push your code to

a web UI to that view your repositories, with their files and commits

a number of extra features (managing your team and accesses, …) Two GitHub features you have to get familiarized with are:

Forks : you can fork any repository on GitHub, and it will duplicate the repository’s codebase into repository that you own. For instance, if you fork twbs/bootstrap, and your GitHub username is “my_username”, then it will create the my_username/bootstrap repository, and it will remember where it was forked from. Usually, you aren’t allowed to push on other people’s repositories, so that will give you a repository that you can push to, since you own it.

Pull requests: once you’ve pushed your code to your repository (or sometimes to a branch of the main repository, if you’re allowed), then you can create a pull request towards the main repository’s master branch. Somebody in charge of the main repository will review your pull request (potentially asking you to change a couple of things), and merge it if it’s suitable to be in the main product.

GitHub has many competitors, two of the main ones being GitLab and BitBucket (which provide very similar services). We chose to make you use GitHub because that’s where most of the industry is (that way, you’ll be able to interact with them on their open-source projects), and it’s also where tech recruiters typically go check out to see what you’ve been up to.

Da New Boss!

Lord Inquisitor! It is with great regret that I inform you that the research group you sent to the planet 09-76C was attacked by xenos. Part of the group was captured by orks; may the God-Emperor have mercy on their souls. Fortunately, two weeks after they disappeared from the radars, we managed to intercept a fragment of the broadcast from the BONE implant of one of the captive ogryn bodyguards. We'll continue to try to determine the coordinates of the broadcast source. I have attached the translation of the broadcast to this message, in case you are interested in it. God-Emperor be with us.

[codingquill]

Welcome back, coding enthusiasts! Today we'll talk about Git & Github , the must-know duo for any modern developer. Whether you're just starting out or need a refresher, this guide will walk you through everything from setup to intermediate-level use. Let’s jump in!

What is Git?

Git is a version control system. It helps you as a developer:

Track changes in your codebase, so if anything breaks, you can go back to a previous version. (Trust me, this happens more often than you’d think!)

Collaborate with others : whether you're working on a team project or contributing to an open-source repo, Git helps manage multiple versions of a project.

In short, Git allows you to work smarter, not harder. Developers who aren't familiar with the basics of Git? Let’s just say they’re missing a key tool in their toolkit.

What is Github ?

GitHub is a web-based platform that uses Git for version control and collaboration. It provides an interface to manage your repositories, track bugs, request new features, and much more. Think of it as a place where your Git repositories live, and where real teamwork happens. You can collaborate, share your code, and contribute to other projects, all while keeping everything well-organized.

Git & Github : not the same thing !

Git is the tool you use to create repositories and manage code on your local machine while GitHub is the platform where you host those repositories and collaborate with others. You can also host Git repositories on other platforms like GitLab and BitBucket, but GitHub is the most popular.

Installing Git (Windows, Linux, and macOS Users)

You can go ahead and download Git for your platform from (git-scm.com)

Using Git

You can use Git either through the command line (Terminal) or through a GUI. However, as a developer, it’s highly recommended to learn the terminal approach. Why? Because it’s more efficient, and understanding the commands will give you a better grasp of how Git works under the hood.

GitWorkflow

Git operates in several key areas:

Working directory (on your local machine)

Staging area (where changes are prepared to be committed)

Local repository (stored in the hidden .git directory in your project)

Remote repository (the version of the project stored on GitHub or other hosting platforms)

Let’s look at the basic commands that move code between these areas:

git init: Initializes a Git repository in your project directory, creating the .git folder.

git add: Adds your files to the staging area, where they’re prepared for committing.

git commit: Commits your staged files to your local repository.

git log: Shows the history of commits.

git push: Pushes your changes to the remote repository (like GitHub).

git pull: Pulls changes from the remote repository into your working directory.

git clone: Clones a remote repository to your local machine, maintaining the connection to the remote repo.

Branching and merging

When working in a team, it’s important to never mess up the main branch (often called master or main). This is the core of your project, and it's essential to keep it stable.

To do this, we branch out for new features or bug fixes. This way, you can make changes without affecting the main project until you’re ready to merge. Only merge your work back into the main branch once you're confident that it’s ready to go.

Getting Started: From Installation to Intermediate

Now, let’s go step-by-step through the process of using Git and GitHub from installation to pushing your first project.

Configuring Git

After installing Git, you’ll need to tell Git your name and email. This helps Git keep track of who made each change. To do this, run:

Master vs. Main Branch

By default, Git used to name the default branch master, but GitHub switched it to main for inclusivity reasons. To avoid confusion, check your default branch:

Pushing Changes to GitHub

Let’s go through an example of pushing your changes to GitHub.

First, initialize Git in your project directory:

Then to get the ‘untracked files’ , the files that we haven’t added yet to our staging area , we run the command

Now that you’ve guessed it we’re gonna run the git add command , you can add your files individually by running git add name or all at once like I did here

And finally it's time to commit our file to the local repository

Now, create a new repository on GitHub (it’s easy , just follow these instructions along with me)

Assuming you already created your github account you’ll go to this link and change username by your actual username : https://github.com/username?tab=repositories , then follow these instructions :

You can add a name and choose wether you repo can be public or private for now and forget about everything else for now.

Once your repository created on github , you’ll get this :

As you might’ve noticed, we’ve already run all these commands , all what’s left for us to do is to push our files from our local repository to our remote repository , so let’s go ahead and do that

And just like this we have successfully pushed our files to the remote repository

Here, you can see the default branch main, the total number of branches, your latest commit message along with how long ago it was made, and the number of commits you've made on that branch.

Now what is a Readme file ?

A README file is a markdown file where you can add any relevant information about your code or the specific functionality in a particular branch—since each branch can have its own README.

It also serves as a guide for anyone who clones your repository, showing them exactly how to use it.

You can add a README from this button:

Or, you can create it using a command and push it manually:

But for the sake of demonstrating how to pull content from a remote repository, we’re going with the first option:

Once that’s done, it gets added to the repository just like any other file—with a commit message and timestamp.

However, the README file isn’t on my local machine yet, so I’ll run the git pull command:

Now everything is up to date. And this is just the tiniest example of how you can pull content from your remote repository.

What is .gitignore file ?

Sometimes, you don’t want to push everything to GitHub—especially sensitive files like environment variables or API keys. These shouldn’t be shared publicly. In fact, GitHub might even send you a warning email if you do:

To avoid this, you should create a .gitignore file, like this:

Any file listed in .gitignore will not be pushed to GitHub. So you’re all set!

Cloning

When you want to copy a GitHub repository to your local machine (aka "clone" it), you have two main options:

Clone using HTTPS: This is the most straightforward method. You just copy the HTTPS link from GitHub and run:

It's simple, doesn’t require extra setup, and works well for most users. But each time you push or pull, GitHub may ask for your username and password (or personal access token if you've enabled 2FA).

But if you wanna clone using ssh , you’ll need to know a bit more about ssh keys , so let’s talk about that.

Clone using SSH (Secure Shell): This method uses SSH keys for authentication. Once set up, it’s more secure and doesn't prompt you for credentials every time. Here's how it works:

So what is an SSH key, actually?

Think of SSH keys as a digital handshake between your computer and GitHub.

Your computer generates a key pair:

A private key (stored safely on your machine)

A public key (shared with GitHub)

When you try to access GitHub via SSH, GitHub checks if the public key you've registered matches the private key on your machine.

If they match, you're in — no password prompts needed.

Steps to set up SSH with GitHub:

Generate your SSH key:

2. Start the SSH agent and add your key:

3. Copy your public key:

Then copy the output to your clipboard.

Add it to your GitHub account:

Go to GitHub → Settings → SSH and GPG keys

Click New SSH key

Paste your public key and save.

5. Now you'll be able to clone using SSH like this:

From now on, any interaction with GitHub over SSH will just work — no password typing, just smooth encrypted magic.

And there you have it ! Until next time — happy coding, and may your merges always be conflict-free! ✨👩‍💻👨‍💻

Mini React.js Tips #2 | Resources ✨

Continuing the #mini react tips series, it's time to understand what is going on with the folders and files in the default React project - they can be a bit confusing as to what folder/file does what~!

What you'll need:

know how to create a React project >> click

already taken a look around the files and folders themselves

What does the file structure look like?

✤ node_modules folder: contains all the dependencies and packages (tools, resources, code, or software libraries created by others) needed for your project to run properly! These dependencies are usually managed by a package manager, such as npm (Node Package Manager)!

✤ public folder: Holds static assets (files that don't change dynamically and remain fixed) that don't require any special processing before using them! These assets are things like images, icons, or files that can be used directly without going through any additional steps.

✤ src folder: This is where your main source code resides. 'src' is short for source.

✤ assets folder: This folder stores static assets such as images, logos, and similar files. This folder is handy for organizing and accessing these non-changing elements in your project.

✤ App.css: This file contains styles specific to the App component (we will learn what 'components' are in React in the next tips post~!).

✤ App.jsx: This is the main component of your React application. It's where you define the structure and behavior of your app. The .jsx extension means the file uses a mixture of both HTML and JavaScript - open the file and see for yourself~!

✤ index.css: This file contains global styles that apply to the entire project. Any styles defined in this file will be applied universally across different parts of your project, providing a consistent look and feel.

✤ main.jsx: This is the entry point of your application! In this file, the React app is rendered, meaning it's the starting point where the React components are translated into the actual HTML elements displayed in the browser. Would recommend not to delete as a beginner!!

✤ .eslintrc.cjs: This file is the ESLint configuration. ESLint (one of the dependencies installed) is a tool that helps maintain coding standards and identifies common errors in your code. This configuration file contains rules and settings that define how ESLint should analyze and check your code.

✤ .gitignore: This file specifies which files and folders should be ignored by Git when version-controlling your project. It helps to avoid committing unnecessary files. The node_modules folder is typically ignored.

✤ index.html: This is the main HTML file that serves as the entry point for your React application. It includes the necessary scripts and links to load your app.

✤ package.json: A metadata file for your project. It includes essential information about the project, such as its name, version, description, and configuration details. Also, it holds a list of dependencies needed for the project to run - when someone else has the project on their local machine and wants to set it up, they can use the information in the file to install all the listed dependencies via npm install.

✤ package-lock.json: This file's purpose is to lock down and record the exact versions of each installed dependency/package in your project. This ensures consistency across different environments when other developers or systems install the dependencies.

✤ README.md: This file typically contains information about your project, including how to set it up, use it, and any other relevant details.

✤ vite.config.js: This file contains the configuration settings for Vite, the build tool used for this React project. It may include options for development and production builds, plugins, and other build-related configurations.

Congratulations! You know what the default folders and files do! Have a play around and familiarise yourself with them~!

The Quiz App: Final.

Hello everyone, If you follow me or happen to have seen the post I made on the 21st of August (this post precisely) I casually made a request because I was tired of coding alone(still am 😆) and people showed interest starting with @xiacodes. Immediately- We talked about what we wanted to do causally and it ended up being "The Quiz App", We had a few calls on the Codeblr Discord to decide what we wanted to do and where we would stop, with @lazar-codes joining us later on to contribute. We digressed a bit and talked about other things lol but you get it.

Active Contributors

@xiacodes did 99% of the styling (she really loves styling) and it turned it great.

@lazar-codes suggested Trello(a task-management system) which we use to organize tasks and check progress.

I did the documentation, helped with the quiz-app logic, and theme mode and I was generally just all over the place offering help here and there, also being a sponge absorbing all the new pieces of information. 🤩🤩 Today, I merged the testing branch with the master branch, bringing an end to an experience that I want to cherish forever.

(I clearly suck at Geography lol) ⚠⚠⚠ I also want to take this opportunity to encourage Web Developers + programmers to contribute to open-source projects: It's one of the best ways to learn from other people, share ideas and put your Git knowledge into practice. Check out The Quiz App here The Quiz App (mmnldm.github.io) Special Shout-Out to @a-fox-studies Your presence is always appreciated!

[iglunix-official]

I’m officially connected to the Iglunix project. If you need some help with installing it, have this guide:

0. Boot an iso that isn’t @voidlinux and install xbps-static. This is important because Iglunix doesn’t currently have an iso.

1. Make two partitions on an empty drive. If using (G)Parted/KDE Partition Manager, using they should be a fat32 partition named IGLU_BOOT and an ext4 partition named IGLU_ROOT, if not, use fdisk to create the two partitions and mkfs to format them.

2. Make directory as root:

3: Mount IGLU_ROOT to /mnt/new-root

4: make a boot directory: /mnt/new-root/boot

5: mount IGLU_BOOT to /mnt/new-root/boot

6: xbps-install -r/path/to/mountpoint -SyfRhttps://mirror.iglunix.org/ (all .xbps files listed in the repo)

7: download this script and run it as root: https://raw.githubusercontent.com/anoraktrend/Iglu-install/main/postinstall

8: reboot, removing the iso. when dhcpcd is done running, hit enter and edit /etc/inittab to make it more secure: replace the ask firsts with respawn and change /bin/sh to /bin/sgetty 0 tty(match the tty at the beginning of the stanza) and add at least two more lines like tty1 with numbers

9: reboot one more time, and login as root. Congrats you have working Iglunix install, git clone https://github.com/iglunix/iglunix to wherever you want to keep your source code directories and optionally clone https://github.com/anoraktrend/frankensrc. Build packages with iglupkg, install using iglu add out/*.xbps.

If you want to contribute to this project, try making pull requests to Frankensrc first (I am more likely to make merges than Ella is, just based on freetime) and Iglunix second, (all Frankensrc build.shs are dual licensed as Berkeley Artistic and bsd0 to be upsourced to Iglunix).

Here be dragons: The Iglunix project does not officially support installing Iglunix at the moment. It’s not complete and many parts of it are not currently working. I can help you if you have issues installing the system if you need it, send an ask if you have trouble! My recommendation is to use a Chimera Linux iso for step zero. (You will need to run doas apk add chimera-repo-contrib chimera-repo-user to be able to install gparted).

Quote of the Week

Panstromek: I remember reading somewhere (probably here) that borrow checking has O(n^3) asymptotic complexity, relative to the size of the function.

Nadrieril: Compared to match exhaustiveness which is NP-hard and trait solving which is undecidable, a polynomial complexity feels refreshingly sane.

– Panstromek and Nadrieril on zulip

Thanks to Kevin Reid for the suggestion!

A beginners guide to GIT: Part 3 - How to learn GIT after (or instead of ) this guide

Table of content: Part 1: What is GIT? Why should I care?

Part 2: Definitions of terms and concepts

Part 3: How to learn GIT after (or instead of ) this guide.

Part 4: How to use GIT as 1 person

Part 5: How to use GIT as a group.

First of all, GIT have a website:

And besides downloading GIT if you do not already have it, it has THE GIT book. It is honestly very good and contains quite a few translations

Second, GIT is one of the old pieces of tech. This means that it is open source, free, and that it contains its own documentation and guides.

If you are ever stuck, or confused about something in GIT, you can use the help command.

Simply writing

git help

Shows you the porcelain commands, and tells you that adding the option -a like so:

git help -a

gives you ALL commands

and the option -g gives you all the guides the manual have, like so

git help -g

If you give help another command,, it will bring you to the manual page for that command

for example, someone on the internet told you to write 

git help reset --hard

and you want to know what that means before running it? Write

git help reset

And you will be shown the manual page for “reset”. Including what --hard does. (To understand the manual, you need to understand the concepts and terms from part 2.)

If you want more visual explanations, Atlassian's guides are public and also quite good  (But , remember. Atlassian uses Bitbucket. Bitbucket is 99% GIT, but can still have tiny differences)
