This tool adds zero-value return values to incomplete Go return
statements, to save you time when writing Go. It is inspired by
and based on goimports.

For example, the following incomplete return statement:

func F() (*MyType, int, error) { return errors.New("foo") }

is made complete by adding nil and 0 returns (the zero values for
*MyType and int):

func F() (*MyType, int, error) { return nil, 0, errors.New("foo") }

To install:

go get -u github.com/sqs/goreturns

To run:

goreturns file.go

To view a diff showing what it'd do on a sample file:

goreturns -d $GOPATH/github.com/sqs/goreturns/_sample/a.go

Editor integration: replace gofmt or goimports in your post-save hook
with goreturns. By default goreturns calls goimports on files before
performing its own processing.

It acts the same as gofmt (same flags, etc) but in addition to code
formatting, also fixes returns.
