Let's explore how to set up Golang

Golang is a strongly typed programming language that originated from Google and exhibits excellent performance and scalability. Golang provides powerful syntax structures that make it widely used in various applications, web development, system management and other fields.

When developing with Golang, we need to set up its environment correctly. Let us discuss the setting method of Golang together.

1. Check operating system

Golang supports various operating systems, including Windows, macOS, Linux and FreeBSD. Before installing Golang, please double-check the version and architecture of your operating system. If you are using a Windows system, please check whether your system is a 64-bit version. If you're using Linux, check to see if your distribution supports glibc 2.12 or higher.

2. Download and install Golang

Before setting up Golang, we must first download and install it. You can download the Golang installation package from the Golang official website. The installation package includes Golang binary files and some other tools. It is recommended to download the latest version of Golang. The installation process is very simple, just run the installation package and follow the prompts.

3. Set environment variables

After installing Golang, we need to set the PATH environment variable to ensure that the system can find the Golang executable file. In Windows systems, we can find how to set environment variables: Right-click "Computer" -> "Properties" -> "Advanced System Settings" -> "Environment Variables". In the list of system variables, find PATH and click "Edit". Enter the Golang installation path in the text box, and use an English semicolon to separate it from other paths. For example:

C:\Go\bin

On Linux and macOS systems you need to edit your shell configuration file (e.g. ~/.bashrc or ~/.bash_profile) to set the PATH environment variable. Add the following line at the end of the file:

export PATH=$PATH:/usr/local/go/bin

This will tell the system to add Golang in the PATH variable installation path.

4. Verify installation

After completing the above steps, we can verify whether Golang is installed correctly. Open a terminal and enter the following command:

go version

If everything is fine, you should see output similar to the following:

go version go1.16.3 windows/amd64

This means you have successfully installed Golang and the system can now recognize it.

5. Editor settings

Golang is a very flexible language that supports various editors and IDEs. No matter which editor you choose, you can set up Golang in it.

In Visual Studio Code, we can use the Go plug-in to set up Golang. After installing the Go plugin, we can open the command palette in Visual Studio Code and enter the following command to set up Golang:

Go: Install/Update Tools

This will Opens a tool window where you can select all the tools you want to install, such as goimports, golint, gorename, etc. These tools can help you write Golang code faster and make your code more standardized.

In Sublime Text, we can use the GoSublime plug-in to set up Golang. After installing the plugin, you can open Sublime Text and press Ctrl Shift P, then enter the following command:

Preferences: GoSublime Settings User

This will open a JSON file, in this file you can set all options related to Golang.

6. Start using Golang

The setup of Golang is complete and now you can start using it to write code. Golang has a simple structure and is suitable for writing concurrent and distributed systems. It uses C's memory allocator and scheduler, allowing you greater control over your code.

Golang also provides very good documentation and examples, which can be used to learn and get more inspiration. You can visit http://golang.org/doc/ for more information. At the same time, you can also join the Golang community, ask questions and share your code.

The above are some tips and suggestions on how to set up Golang. Hope this article is helpful to you.
