goimports

Updates Go import lines, adding missing ones and removing unreferenced ones. More information: https://godoc.org/golang.org/x/tools/cmd/goimports.

• Display the completed import source file:

goimports path/to/file.go

• Write the result back to the source file instead of stdout:

goimports -w path/to/file.go

• Display diffs and write the result back to the source file:

goimports -w -d path/to/file.go

• Set the import prefix string after 3rd-party packages (comma-separated list):

goimports -local path/to/package1,path/to/package2,... path/to/file.go
