clean remove object files and cached files
doc show documentation for package or symbol
env print Go environment information
fix update packages to use new APIs
fmt gofmt (reformat) package sources
generate generate Go files by processing source
get add dependencies to current module and install them
install compile and install packages and dependencies
list list packages or modules
mod module maintenance
work workspace maintenance
run compile and run Go program
test test packages
tool run specified go tool
version print Go version
vet report likely mistakes in packages
Use "go help <command>" for more information about a command.

Use "go help <topic>" for more information about that topic.
- 示例：查看go和c调用帮助信息
$ go help c
There are two different ways to call between Go and C/C++ code.
The first is the cgo tool, which is part of the Go distribution. For
information on how to use it see the cgo documentation (go doc cmd/cgo).
The second is the SWIG program, which is a general tool for
interfacing between languages. For information on SWIG see
http://swig.org/. When running go build, any file with a .swig
extension will be passed to SWIG. Any file with a .swigcxx extension
will be passed to SWIG with the -c++ option.
When either cgo or SWIG is used, go build will pass any .c, .m, .s, .S
or .sx files to the C compiler, and any .cc, .cpp, .cxx files to the C++
compiler. The CC or CXX environment variables may be set to determine
the C or C++ compiler, respectively, to use
2 go run¶
3 go build¶
https://blog.abnerzhao.com/posts/go-build/
- 功能：构建go代码，生成可执行文件
- 语法：go build [-o output] [build flags] [packages]
- -o output：指定生成的可执行文件名
- -a：强制重新构建。（默认在已经有生成的可执行文件后，源文件没有更新，就不会重新构建）
- -compiler name：指定go编译器，可选gc和gccgo，默认使用go自带的gc编译器，gccgo是GCC编译器
4 go clean¶
- 功能：清理编译的object文件
- 语法：
go clean [clean flags] [build flags] [packages]
5 go get¶
- 功能：下载指定的go module包
- 语法：
go get [-d] [-t] [-u] [build flags] [packages]go get example.com/pkg：下载或更新最新版go get example.com/pkg@v1.2.3：下载或更新到指定tag版go get golang.org/x/text@master：下载或更新master分支版go get example.com/mod@none：移除module，并下载依赖包

- 功能：编译并打包应用
7 go env¶
- 功能：查看环境变量
8 go mod¶
9 go doc¶
