Go Learning Notes (1) – Ubuntu Go environment setup, VS Code Configuration of the Go development environment, VS Code remote development configuration

1. Installation instructions

Go 1.4 is required to install the Go 1.11 compiler directly in Ubuntu. So if in the use of apt – get the install installed go when refer to the following link: blog.csdn.net/y5492853/ar…

Overseas official website golang.org/dl/

Domestic official website golang.google.cn/dl/

2. Install Go 1.12

1. Downloading the Installation package

Wget HTTP: / / https://dl.google.com/go/go1.12.4.linux-amd64.tar.gzCopy the code

2. Decompress to the /usr/local directory

Sudo tar -c /usr/local-xzf go1.12.4.linux-amd64.tar.gzCopy the code

3. Modifying environment Variables

vi ~/.profile
Copy the code

Add after the file

Export GOROOT="/usr/local/go" // Go installation directory. That is, decompress the specified path export GOPATH=$HOME/gocode // Locally configured Go code directory export GOBIN=$GOPATH/bin // Directory for storing the compiled Go code executable file export PATH=$PATH:$GOPATH:$GOBIN:$GOROOT/bin // Add the Go installation directory to the operating system PATHCopy the code

4. Save and exit, and execute

source ~/.profile
Copy the code

5. Restart the system
6. Check whether the installation is successful

wohu@wohu:~$go Version go Version go1.12.4 Linux/AMD64Copy the code

3. The first Go program

Create a new text file, hello, with the suffix.go, and edit the following

package main    

import "fmt"

func main(a) {
    / * comment * /
   fmt.Println("Hello, World!")}Copy the code

Execute the above code output

$ go run hello.go 
Hello, World!
Copy the code

3.2 Go source code features

• The source program to.goFor the suffix
• The source program defaults toUTF-8 coding
• Identifiers are case sensitive
• The semicolon at the end of the statement can be omitted
• Functions tofuncAt the beginning of the function body{Must be at the end of the line where the function header resides
• stringLiteral usage""Double quotation marks;characterliteralruneuse' 'Enclosed in single quotes
• Call the method used in the package.Click on an accessor, just like Python
• mainThe package name of the function must bemain
• Strongly typed statically compiled languages
