GOFMT is a code formatting tool that only organizes code formatting to ensure that everyone's code is formatted uniformly.

golint

The Golint tool is a code quality check that gives some best practice guidelines. Look at the following code:

After the Golint.

main.go:8:5: error var SomeError should have name of the form ErrFoo  main.go:8:5: exported var SomeError should have comment or be unexported  main.go:16:9: if block ends with a return statement, so drop this else and outdent its block  

First line: SomeError the format of the variable should be the beginning of err.

The second line: SomeError the uppercase start can be referenced outside the package, so you need to write a comment at the declaration. or change to lowercase, not to be quoted outside the package.

The third line: the IF condition has a return statement, so the else block is not required.

After the modification, the golint is executed again, and the error disappears.
