以下命令基于go版本1.15.3进行测试

根本命令

go helpgo envgo version

穿插编译

# Windows下编译LinuxSET CGO_ENABLED=0SET GOARCH=amd64SET GOOS=linuxgo build xx.go

编译参数

go build

  • 当编译包时，会主动疏忽'_test.go'的测试文件。
# go build -o 指定编译输入的名称 # win下编译生成指定名称的可执行文件go build -o custom.exe send.go

gofmt 和 go fmt

go fmt 是 gofmt的繁难封装

go fmt 即 gofmt -l -w

传入文件的话，会格式化这个文件。传入目录的话，会格式化该目录下的所有.go文件

// 罕用go fmtgo fmt send.go
// gofmt 参数usage: gofmt [flags] [path ...]  -cpuprofile string        write cpu profile to this file  -d    display diffs instead of rewriting files  -e    report all errors (not just the first 10 on different lines)  -l    list files whose formatting differs from gofmt's  -r string        rewrite rule (e.g., 'a[b:len(a)] -> a[b:]')  -s    simplify code  -w    write result to (source) file instead of stdout
// go fmt 参数 usage: go fmt [-n] [-x] [packages]Fmt runs the command 'gofmt -l -w' on the packages namedby the import paths. It prints the names of the files that are modified.For more about gofmt, see 'go doc cmd/gofmt'.For more about specifying packages, see 'go help packages'.The -n flag prints commands that would be executed.The -x flag prints commands as they are executed.To run gofmt with specific options, run gofmt itself.See also: go fix, go vet.
