Go is an open source programming language with features such as efficiency, simplicity, and security. It is currently widely used in the Internet field. The naming rules of the Go language are very confusing, especially for beginners, it may be difficult to modify the name in Go. So, how should we quickly change the name? This article will introduce it to you in detail.

Go language has become the new favorite of programmers with its simple and efficient development style. The naming rules in GO are relatively unique compared to other languages, so it may be more troublesome when refactoring or modifying the code.
To modify the name in Golang, we need to follow the following steps:
Step 1: Install the editor
Before modifying the code, we need to first install it on the computer Install a Go editor on your computer. Commonly used editors include: Sublime Text, GoLand, Visual Studio Code, and VS Code is recommended. After installing VS Code, we need to install the Go language plug-in to better write Golang code.
Step 2: Create a project
Before making code modifications, we need to create a new project in the project directory. Use the following command:
mkdir projectName
The above command will create a folder named projectName
in the corresponding directory as the new project directory.
Step 3: Modify the code
1. Modify the variable name
In the Go language, we can modify the variable name through simple variable assignment. For example, if we want to change the variable name from a
to b
, we can do it as follows:
a := "old" b := a //将a 赋值为 b fmt.Println(b) //输出结果 old
In the above code, we change the variable a
is assigned to variable b
, thus modifying the variable name.
2. Modify the function name
If we want to modify the name of the function, we need to first find the location of the function. After modifying the function name, we need to modify all the function calling locations.
For example, we originally had a function A
, and now we want to modify it to B
. Then we need to change all places where the A function is called to B in the code. Otherwise, the program will compile with errors.
3. Modify the structure name
The structure is an important data type in Golang, so you need to pay special attention when modifying the structure name. If we want to modify a structure name, such as changing the name from A
to B
, we need to perform the following steps:
Search for the structure name through the editor, Replace all structure names with B
. It should be noted that if the structure is used by other code, the part of the code that calls the structure needs to be modified to a new name before performing this step, otherwise the program will compile and error.
Step 4: Test the modified code
The modification of the code must eventually be tested to ensure that there are no errors in the function of the program. In Golang, we can use the testing tool go test
to test the modified code. The testing tool will automatically run the test cases in the package to ensure that the modified program can run properly.
Execute the following command:
go test ./...
This command will run all test scripts found in the current directory and subdirectories, and output the results generated during the running process to the terminal.
Through testing with testing tools, we can check whether there are unknown errors in the program so that we can fix them in time.
Summary
Modifying the name in Golang requires following certain steps. Although the process may be cumbersome, after modification, the code can be made clearer, easier to read, and easier to maintain. Therefore, during the development process, we should promptly modify the variable names, function names, structure names, etc. in the code to ensure the development of high-quality programs.
