How to learn open source projects + social on Git Hub

background

As a professional open source website, Git Hub implements various functions based on the version control software Git. It is a paradise for programmers to exchange experience and learn open source projects.

However, due to the large differences in learning methods and programming thinking at home and abroad, many people in the country are still puzzled by the use of Git Hub. Most people still don't understand how to find open source projects that meet their needs from Git Hub and read and learn, how to contribute to other people's projects, and how to communicate with other programmers.

The author has also experienced a long period of confusion, and now I dare to write some personal experiences to help everyone avoid detours.

Precondition

• Know basic Git commands, make commands
• Linux/Unix system is installed, Mac should also work
• Will use basic bash commands
• Have your own Git Hub account

@The above is just a suggestion, I can't imitate it! ^_

   cd cppworkshop/
   make distclean
   make debug=1
   

7. execute project;

   ./bin/memerr
   

8. In-depth study of the project, such as reading the source code, modifying the source code, etc.

Fork other people's projects and apply for Pull Request

Sometimes, we not only want to view other people's projects, but also want to join the project development, but due to the lack of relevant permissions, we can only Fork the project as an outsider, modify it locally, submit it to the personal warehouse, and then apply to the original author for Pull Request.

step

1. Search for projects you are interested in on Git Hub;

2. Click the Forkbutton in the upper right corner of the project to add the project to the personal warehouse;
   

3. On the local computer, use the operations mentioned above to pull the project from the Fork from the personal warehouse (note! It is your own Git Hub URL, not the original author's project URL, the name is different);

   git clone https://github.com/gkzscs/cppworkshop.git
   

4. Make project modifications locally;

5. Use the Git command to submit the modification to your Git Hub warehouse, and add a comment on the modification content;

   git add <files>
   git commit
   git push
   

6. On the Git Hub webpage, enter the project directory from your Fork and create a Pull Request (more cumbersome);
   

7. Waiting for the original author's confirmation (can meet but not ask).
