Introduction to Git

I believe everyone has used SVN, but SVN will be limited by the network. When I joined a company before, there were many things on SVN that needed check out, which were extremely affected by the network and sometimes interrupted, and the efficiency was very low. While Git has the advantages of SVN, it can solve this problem perfectly. This is also the difference between centralized and distributed version control systems
CVS and SVN are both centralized version control systems, while Git is a distributed version control system.

Scene

Now a little size of the company are using GitFlow mode for branch management, although plug-ins bring us great convenience, but switch branch, find branch, branch is still so troublesome

Demand

In the primary and secondary countries of society, every working people living at the bottom, they work silently, all kinds of 996, multi-thread work

Every code farmer colleagues are carrying out a lot of needs, in order to make our work more efficient! We also give ourselves a few needs!

Set up quickly hotfix/feature Branching Quickly switch to specified working branches among numerous local branches Clearly describe the task description corresponding to each branch

.......

For this reason, the idea of enhancing the native git has long appeared, but one has not written ~, so I will use Python to upgrade today!

Under development

Establish a warehouse Realize viewing all branches Create a branch, Fast branch switching help information

When creating a branch, prompt for task name, description, etc. When viewing all branches, mark the corresponding index number on the branches, switch the specified index number to switch branches, and display the branch description when colleagues display 


Savey:baking-apiserver:% g -b                                                                                                                  <test>

Compatible with native git Use 


Savey:baking-apiserver:% g version                                                                                                 
git version 2.24.3 (Apple Git-128)

Adds a description for the current branch

Well, I forgot to write the description when I first set up the branch, so I will quickly write the description to the branch again without typing it git config branch.<branchName>.description It's over

Just like this now 


Savey:baking-apiserver:% g --desc test Branching                                                                                                      
✅Success!!

Because there will be more and more instructions, before in cmdDict.py It is not appropriate to configure the specified command directly. Today, it was changed to the following writing. Use the features of the generator to improve the little performance, because before that, my old family php Also support main.py0 . So today the index to modify it! By the way cmdDIct.py Change one's name Config.py Isn't it better?
Take the previous instructions to the specific class to implement. 


def keyCommand():
		yield printCurrentBrStrategy.PrintBr()
		yield gtaskHelp.GtaskHelper()
		yield createTaskStrategy.CreateTask()
		yield switchBranch.SwitchBranch()
		yield editBrDesc.EditBrDesc()

In abstract classes AbstractCommandStrategy.py Adding method 


    """
     Implementation method of stored instruction 
    """
    @abstractmethod
    def command(self):
        pass

Configure the corresponding subclass by specific subclasses command Orders. For example 


from . import commandStrategy

class PrintBr(commandStrategy.AbstractCommandStrategy):

    """  
       Configured here   Specified instruction  
    """
    def command(self):
        return "-b"
    def cmd(self, args):
        super().printAllBr(args)


    def useage(self):
        print(self.command() + "\t Print out all current branches, list index numbers and descriptions ")
        pass

Try to take a small step on the first day
