Golang的开发团队制定了统一的官方代码风格,并且推出了gofmt工具(gofmt或go fmt)来帮助开发者格式化他们的代码到统一的风格。gofmt是一个cli程序,会优先读取标准输入,如果传入了文件路径的话,会格式化这个文件,如果传入一个目录,会格式化目录中所有.go文件,如果不传参数,会格式化当前目录下的所有.go文件。
gofmt默认不对代码进行简化,使用-s参数可以开启简化代码功能,具体来说会进行如下的转换:
2.使用
(base) $ go help fmt
usage: go fmt [-n] [-x] [packages]
Fmt runs the command 'gofmt -l -w' on the packages named
by 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.
