我的GO+语言初体验-Go+入门安装避坑手册

一、入门简介

英文介绍

• For engineering: working in the simplest language that can be mastered by children.
• For STEM education: studying an engineering language that can be used to work in the future.
• For data science: communicating with engineers in the same language.

重点翻译：

• 工程上用： 简单好用
• STEM教育：简单好用
• 科学数据：简单好用

二、官方文档

代码库： 

​​GitHub - goplus/gop: GoPlus - The Go+ language for engineering, STEM education, and data science​​

官方网站：

• ​​Go+ by Tutorials​​

中文社区：

GO+入门

三、安装步骤

1、下载源码：

 git clone https://github.com/goplus/gop.git

2、安装gop

 这就有点尴尬了

 是个啥

程序员的标准动作

摆个度

​​Go下载 - Go语言中文网 - Golang中文社区 (studygolang.com)​​

先去下载go

胜利就在眼前

 高兴太早

go: github.com/goplus/gox@v1.8.0: Get "https://proxy.golang.org/github.com/goplus/gox/@v/v1.8.0.mod": dial tcp 172.217.27.145:443: connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
go: github.com/goplus/gox@v1.8.0: Get "https://proxy.golang.org/github.com/goplus/gox/@v/v1.8.0.mod": dial tcp 172.217.27.145:443: connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

意思就是你下不了需要换一下

设置goproxy

PS D:\git\2021\goplus\gop>  $env:GO111MODULE = "on"
PS D:\git\2021\goplus\gop> $env:GOPROXY = "https://goproxy.cn"

安装gop

 D:\git\2021\goplus\gop>go run cmd/install.go --install --autoproxy
Installing Go+ tools...
go: downloading github.com/goplus/gox v1.8.0
go: downloading github.com/qiniu/x v1.11.5
go: downloading golang.org/x/mod v0.5.1
go: downloading golang.org/x/tools v0.1.7

go build: cannot write multiple packages to non-directory D:\git\2021\goplus\gop\bin

意思很明显了

那就new一个

 执行一下 ./all.bat

安装成功

Go+ tools installed successfully!
Next:
We just installed Go+ into the directory:  D:\git\2021\goplus\gop\bin

To setup a better Go+ development environment,
we recommend you add the above install directory into your PATH environment variable.

验证环境

按直觉都行不通 

查看gop的bin目录

PS D:\git\2021\goplus\gop\bin> .\gop.exe
Gop is a tool for managing Go+ source code.

Usage:

        gop  [arguments]

The commands are:

        run         Run a Go+ program
        go          Convert Go+ packages into Go packages
        fmt         Format Go+ packages
        mod         module maintenance
        install     Build Go+ files and install target to GOBIN
        build       Build Go+ files
        clean       Clean all Go+ auto generated files
        env         prints Go+ environment information.
        test        Test Go+ packages
        version     Version prints the build information for Gop executables

Use "gop help " for more information about a command.

验证成功

四、DEMO实战

官方例子

​​Go+ by Tutorials: Hello world (goplus.org)​​

​​The Go+ Playground (goplus.org)​​

1、允许结果

2、在demo创建helleword.go空白文件

3、写入代码

package main
 
 
import "fmt"
 
 
func main() {
    fmt.Println([]float64{1, 2, 3.4})
}

4、运行命令

 .\gop.exe run ..\demo\helloworld.go

使用感想

1、官网有必要说明一下与go的关系；一开始个人以为和go没什么太大关系，但是实际安装的时候是需要安装go才能安装go+，容易给使用者产生误导；源码中是有依赖的

2、go+有很多特性，如1）有理数：bigint、bigrat、bigfloat，2.地图文字；3. 切片字面量等，可以增加一些demo来引用这些特性，场景化的引导用户使用
