SYNOPSIS
go fmt [-n] [-x] [packages]
gofmt [flags] [path ...]
DESCRIPTION
go fmt formats Go source code according to standard Go style conventions. It is an alias for gofmt -l -w on the packages named by the import paths. The gofmt tool can also simplify code with -s and apply rewrite rules with -r for refactoring.
PARAMETERS
-n
Print commands that would be executed.-x
Print commands as they are executed.-l
List files whose formatting differs (gofmt).-w
Write result to source file (gofmt).-d
Display diffs instead of rewriting (gofmt).-s
