Git for beginners, how to install, use, trading robots


Git is a command-line utility for version control, that is, for keeping a history of changes that the user makes to project files. It is usually used to work on applications, but it can be used in other cases, for example, designers use Git to store different versions of drawings and layouts. Git allows you to rollback an application to an earlier version, compare and analyze changes.

Git for beginners: basic terms and concepts, introductory guide

Before you start working with Git, you need to understand what a repository, commit, and branch are.
A repository is a place where code or other data is stored, as well as a history of their changes. The Git program runs locally and all information is stored on your computer, but you can also use Internet services. The most popular of them is Github. There are two more well-known ones: Bitbucket and GitLab.
Git for beginners, how to install, use, trading robots
A commit is a snapshot of the state of a project at a specific point in time. It has a unique ID and comments.
A branch is a history of changes made to a project. It has its own name and consists of commits. A repository can have multiple branches that branch off or merge with other branches.

How Git Works

Let’s show visually how the Git storage system is arranged, using a simple drawing as an example.
Git for beginners, how to install, use, trading robotsHere the circles represent the commits, and the arrows show which one refers to which. Since everyone refers to the previous one, C3 is the newest, C2 is the older version, and so on, up to the very first one in this C0 branch. This is the master branch, commonly referred to as master. The rectangle labeled main* inside shows which commit you are currently working on. In the figure, you see a simple graph with one branch and four commits. Git is also able to work with complex graphs that include several branches that can merge into one.

Installing Git

Git is a console utility that can run on Windows, Mac OS, and Linux operating systems. We will tell you how to install it for each of them. To install under Windows OS, you need to download the application from the official website and install it.
Git for beginners, how to install, use, trading robotsIf you have Mac OS and installed the Homebrew package manager, type the command:
brew install git If Homebrew is not installed, then run:
git –version After that, in the window that appears, you will be prompted to install the Command Line Tools. Git will also be installed with this utility. For Linux Debian and other distributions based on this version, such as Ubuntu or Mint, the following command is required to install:
sudo apt install gitFor Linux CentOS, you need to enter:
sudo yum install git What is Git, installation and configuration – installation:

Presetting Git

After installing Git, you need to configure it so that each time you create a commit, the name of the author is indicated. To do this, run git and execute the command:
git config –global ”
Here, instead of “Author”, we set our name, for example, “Ivan_Petrov”. After that, you can set the email address with the following command:
git config –global “” In this case, instead of “” we indicate the real email address.

Creating Your First Git Repository

To create a repository, first go to the project folder. For example, on Windows this might be D:/GitProject. Enter the command:
d:\GitProject After that, create the repository:
git init After that, add all the files:
git add –all To add a specific file, enter:
git add filename Now you can create a commit:
git commit -m “comment” Some notes on creating a repository:

  1. A repository can have many files and subfolders (mostly just a regular folder).
  2. It’s best to have a separate repository for each project.
  3. Don’t create folders for a repository inside another repository (avoid matryoshka repositories!).
  4. Changes made to repository folders are “tracked” by Git, but these changes must be added to the repository in order to be tracked or recorded.
  5. You can control the elements that Git “watches”. It is best to ignore very large datasets or temporary files.

When to Commit

Commits in Git are recommended in the following cases:

  • new functionality added to the project;
  • all bugs fixed;
  • you are closing for today and want to save your changes.

Collaborate on Git projects

Let’s say you and your friends came up with a new project and decided to share responsibilities. One will be responsible for the functionality, the other for the design and design, the third for registration, authorization and security. In this case, you need to branch. As already mentioned, a branch is a set of commits going sequentially one after another. The master branch is called master. Other branches are for implementing new features or fixing bugs. Thus, in a separate branch, you can make any changes, and then merge them with the main one. Many experts do not advise creating commits in the main branch, but recommend creating a new one, making changes in it and then merging it into master. To start a new branch, you need to run the command:
git branch
bugFixThis can also be done with the following command:
git checkout –b

The second method differs from the first one in that in this case, after executing the command, you immediately get into the created branch.

It is better to name the new branch with a concise, but at the same time sufficiently capacious and understandable name to prevent confusion in the project. When using your system, you can specify an identifier before the task name. Also, do not forget to leave your comment in each commit you create, which should indicate the essence of the changes. In order to move from one branch to another, you need to run the following command:
git checkout
_1 After finishing work, the changes made to the current branch must be merged into the master, masters. To do this, first checkout the master branch using the command:
git checkout master After that, update the local branch:
masterNow you can merge branches:
bugFix This command adds changes from the branch specified in the (bugFix) command to the branch you are on, in this case master. To view the current state of the branch, you need to enter the command:
git status In order for other users working on the project to see the changes made, you need to push them to the server. To do this, you must first go to the branch that you want to push to github. To enter master, run the command:
git checkout master After that, you can push it to the Github server:
git push origin masterIn order for another person to gain access to the project, you need a service for storing the code, for example, Github. If you have recently joined the project and you need to download it to yourself, run the command:
git clone…/….git

Here…/….git is the address of the repository. It can be obtained by opening the desired project and clicking on the green “Code” button.

Important advice!

It is recommended that you update masters on your local machine before creating a new branch. To do this, enter the desired branch and run the following command:
git pull origin master As a result, the actual changes will be downloaded from github. In the same way, you can update any branch. To update all existing branches, you can run the command:
git pull

A common problem when working with a Git project

When trying to automatically merge changes, it may happen that both branches have changes on the same line in this case when you run the command:
git merge master The following error appears:
CONFLICT (content): Merge conflict in
Automatic merge failed; fix conflicts and then commit the result. In this case, you need to resolve the conflict manually. To do this, open the file in which the error occurred, in our case it is, figure out what’s wrong and troubleshoot. After that, add the corrected file with the command:
git add
py And create a new commit:
git commit -m “Merged conflict”

GitKraken is another application designed to work with various version control systems using the GUI. To get started, you need to register on GitHub and install the GitKraken application. When you start the application, you need to enter your username and password from the GitHub service. In order not to enter a password every time, you need to set up an SSH key. If you don’t already have an SSH key generated, you can follow the GitHub guide on creating a new key. Once you have your SSH key, you can add it to your GitHub account. To do this, select “File” then “Preferences” from the main menu. Then select “Authentication” and provide the paths for your public and private keys. The first step in publishing any content to GitHub is to create a local repository to keep track of your work. This folder will contain all the files that you want to publish to GitHub. You must follow the instructions:

  1. To create a new repository in GitKraken, select “File” from the main menu, then “Init Repo”. There will be several options for different types of repositories, select “Local Only”.
  2. Then select the folder that will be your new repository. You can select an empty folder or a folder that already contains files; you won’t lose your changes.
  3. The next dialog box also contains settings for default templates and license files. Leave everything as it is.
  4. Click “Create Repository”.

You don’t need a Github account to use Git (or GitKraken) locally on your computer. However, if you plan to collaborate with other users or use files from multiple computers, you will need to use a host such as Github. To create a repository on GitHub, after clicking “Init Repo”, select the line “GitHub” and fill in the window that appears as follows:

  1. Account – The name of your GitHub account.
  2. Name – the name of the repository. Compose it from letters, numbers and underscores.
  3. Description – Description of what this repository will contain.
  4. Access – access to a remote location, whether it should be visible to everyone or remain open only to you and the people you add as collaborators
  5. Clone after init – leave this option checked, which will make the repository available to you on GitHub.
  6. Where to clone to – select a location on the computer where the newly created repository folder should be placed.
  7. Finally, click the “Create Repository and Clone” button .

Git for beginners, how to install, use, trading robotsAfter that, a new folder will appear in the upper left corner of the GitKraken interface, and we can see more information about it in the left column. When connecting GitHub to GitKraken, make sure that authorization is performed in either Chrome or Firefox, not Internet Explorer.
