Introduction to code management tools
Simply put, a source code management tool is a tool that allows multiple programmers to collaborate on development at the same time, to manage code and record the history of code editing.
Why use a code management tool?
Imagine if we wanted to restore a code file to its pre-modified state, what would we do?
The easiest way is to back up the source files before editing the code. When backing up, in order to better distinguish files, we usually put the backup file name or directory name on the
Add some identifiers to distinguish versions, such as time or author information. As shown below:
But the above method has the following problems:
- The operation is tedious and error-prone : Before each edit, you need to back up the document in advance, which is troublesome and easy to miss
- Definition of naming rules : If the naming rules of backup files are not defined well, the files will be cluttered and it will be difficult to distinguish the latest documents
- Multiple people cannot collaborate at the same time : if two people edit the same code file at the same time, the content modified by the latter person will overwrite the content modified by the former person
At this time, we can use code management tools to solve these problems.
The role of code management tools
Use code management tools to achieve:
- Version management of code, record modification history, and restore to any previous version at any time
- It can automatically merge and resolve conflicts on the code submitted by multiple people, and finally realize the simultaneous development of multiple people.
Introduction to common code tools
Common code management tools are generally divided into two categories:
- One is a centralized code management tool such as SVN
- One is a distributed code management tool such as Git
Introduction to GitLab
GitLab, an open-source application developed with Ruby on Rails, implements a self-hosted Git project repository, allowing users to access public via a web interface
Open or private projects.
