Golang is a programming language that is different from other programming languages because it combines the characteristics of static and dynamic languages. It has a powerful type system and garbage collection, as well as many features that modern languages do not have. The emergence of Golang has driven the development and innovation of language programming languages to a certain extent, and has become one of the languages that developers are keen to learn and use. So how to activate it when developing with Golang? Below, let’s discuss it in detail.

Download the Golang installation package

First, you need to download the Golang installation package from the official website. During the download process, you need to select the installation package suitable for your operating system to download. Here we take the Windows operating system as an example. After the download is complete, you need to unzip the downloaded installation package to your computer.

Set environment variables

Next, you need to set environment variables in Windows. The function of environment variables is to allow the operating system to find the installation path of Golang anywhere, so that Golang can be used conveniently on the command line. The steps are as follows:

Open the "Control Panel" and enter the "System and Security" option;
Select "System";
In the menu on the left side of the page Select "Advanced System Settings" in the column;
Enter the "Advanced" tab and select "Add" in the "Environment Variables" option;
Add "GOROOT" and "GOPATH" variables, Among them, "GOROOT" is the installation path of Golang, and "GOPATH" is your working directory, that is, the place where you store your own code;
In "System Variables", find the "Path" variable and select "Edit" ";
Select "New" in the new window and add Golang's bin directory. The directory format is: "%GOROOT%\bin".

Verify whether the installation is successful

After the installation is completed, you can enter "go version" on the command line to check whether the installation is successful. If the version number is displayed, the installation is successful. As shown in the figure below:

Install Golang plug-in

In order to better write Golang code, we can install Golang plug-in to help us improve development efficiency and code quality. It is recommended to use VS Code as your editor. VS Code is a lightweight cross-platform editor with perfect debugging functions and a rich plug-in ecosystem.

In VS Code, you need to install the following plug-ins:

Go plug-in: Use the release version of the Golang plug-in for the best experience;
Go Outliner Plug-in: can realize code modularization and management, making your code more complete;
Go-doc plug-in: can view Golang documentation, providing fast search and documentation support.

The above plug-ins can be found, downloaded and installed in the plug-in market of VS Code.

Start working with Golang

After everything is ready, you can start working with Golang. Open your working directory (that is, the src directory under $GOPATH) in the editor and start writing code. You can use an integrated development environment (IDE) or text editor to write and run Golang code. Golang, like other modern languages, also has powerful debugging capabilities. You can use the debugger to view your code and the status of the program when it is running.

Summary

So, how to activate Golang? To activate Golang, you need to download the Golang installation package, set the environment variables, find the Golang installation path in the operating system, install the Golang plug-in in the editor, and then you can start working. Although Golang has a steep learning curve, it is an innovative programming language that is favored by developers for its powerful type system and garbage collection features. We believe that through hard study and practice, you can also become an efficient Golang programmer!
